Definitions

  • the invention relates to a drainage channel for surface drainage with a channel body with at least one opening provided on its top, two side walls and a substantially closed bottom.
  • Such drainage channels are well known and are widely used. In practice, however, it has been found that a not inconsiderable danger is that the side walls break. This was caused in particular by increased lateral loads, but also by inadequate care during installation, in particular shaking the pavement or rolling the asphalt, or also by pressure due to expansion of the material in the adjacent traffic area. By breaking the side walls, the drainage channel is generally damaged so that an expensive replacement is required. A repair on site is usually not possible and otherwise too expensive.
  • a drainage channel of the type mentioned at least one substantially closed stiffening element is provided between the opening and the bottom, which is connected to the two side walls essentially in one piece.
  • the stiffening element is used for the horizontal stiffening and support of the side walls in order to be able to absorb the side forces acting on the drainage channel.
  • the stiffening element forming the stiffening intermediate structure and provided according to the invention is preferably arranged directly under the opening or the bearing surface for the cover grating of the channel body, so that the stiffening and supporting function acts as close as possible to the point of application of the side forces and the leverage produced by the side forces is therefore low.
  • the drainage channel can be installed much more easily.
  • a significant reduction in installation costs can thus be achieved with the aid of the invention.
  • Another advantage of the invention is that the side walls no longer need to be made particularly stable, which was the case in the prior art in order to increase the resistance to the side forces.
  • the stiffening element according to the invention is essentially integrally connected to the two side walls of the channel body, the stiffening element can be produced together with the rest of the channel body in a common single operation and arranged at the desired location between the opening and the floor, so that a separate one Manufacturing step for the stiffening element is omitted, which has a favorable effect on the production costs.
  • the one-piece connection of the stiffening element with the two side walls has structural advantages in terms of statics and stability.
  • support frames for conventional drainage channels which are placed as a separate component on the top of the channel body and can also have a stiffening effect in the horizontal direction transverse to the channel line; however, these support frames (especially when the road surface was subsequently increased) were used to increase the drainage channel. In the event that an increase in the channel surface is not desired or is even impossible, bracing using the known support frame is not possible.
  • the known support frames are also a hindrance when cleaning the drainage channel, since the removal of deposits accumulated on the bottom of the channel body is hindered by the transverse webs from which the known support frames are formed.
  • the stiffening element is expediently formed from the same material as the rest of the channel body, which further simplifies production and thus the associated costs. Additives can be used to adapt the material to requirements, particularly with regard to tightness and corrosion resistance.
  • the stiffening element is essentially closed and at least one liquid drainage means is provided for draining liquid that has entered through the opening from the stiffening element onto the floor.
  • This forms a plane that absorbs the liquid entering through the opening of the channel body, in particular the surface water, over the entire length.
  • the liquid absorbed in this way is discharged from the plane of the stiffening element in the direction of the floor by the liquid drainage means likewise provided according to the invention.
  • the substantially closed stiffening element forms a first hydraulic level within the channel body, in which the liquid entering through the opening is collected before it is discharged downwards by the liquid drainage means into the second hydraulic level, which is formed by the bottom of the channel body.
  • a large part of the dirt carried by the liquid is deposited on the first hydraulic level formed by the stiffening element and can thus be easily removed, since the first hydraulic level formed by the stiffening element is arranged closer to the opening or cover grate and thus much more accessible is.
  • a drainage channel in which a pipe is connected to the channel body, the end connected to a drain is lower than the bottom of the channel body and the cross section of the pipe is dimensioned with regard to the flow parameters of the drainage channel is that at least at the maximum drainage capacity of the channel run in the pipeline pressure pipe drainage conditions; however, this pipeline is an additional component that has to be installed below the bottom of the channel body, which complicates and increases the cost of installing the drainage channel, and no measures for horizontal stiffening are provided for this known drainage channel.
  • the discharge means expediently consists of at least one drainage opening formed in the stiffening element.
  • the top of the stiffening element should have a slope to the drainage means.
  • the upper side of the stiffening element should have a concave cross section, which is advantageous with regard to the static function, the absorption and collection of liquid and dirt and the discharge of the liquid to the discharge means.
  • the cavity formed between the stiffening element and the floor has an essentially round cross section, which is used to collect and transport the amounts of liquid discharged from the stiffening element through the discharge means in the longitudinal direction of the drainage channel.
  • the cavity usually opens into an inlet box or a drain pipe.
  • the cross section of the cavity is circular.
  • a tube extending in the longitudinal direction of the channel, which delimits the cavity, is preferably introduced in the channel body.
  • the use of such a tube is particularly advantageous when the channel body is produced by casting, since in such a case the tube can be used as a 'lost' shape.
  • each channel element has connecting means for essentially sealingly connecting the cavity formed between the stiffening element and the floor to that of the each has the next channel element.
  • the connecting means have a projecting from one end of the channel element, a hollow connector that communicates with the cavity and with its open free end simply in the opening of the cavity on the other end of the the next channel element is insertable.
  • first tube end of the tube protruding from one end face of the channel element and one that is essentially flush with the other end face the second end of the tube form the connecting means, the first tube end of the one channel element being insertable into the second tube end of the next channel element.
  • the cross section of the first tube end should be the same as that of the rest of the tube, while the second tube end is widened in such a way that the first tube end of one channel element lies with its outer surface on the inner surface of the second tube end of the next channel element.
  • the tube for forming the cavity should consist, for example, of plastic, since this is an easy-to-process, inexpensive and corrosion-resistant material;
  • the corrosion resistance can be matched to the conditions by using suitable plastics.
  • precious metal would also be conceivable, for example.
  • the channel body 4 is open at its top 8 over its entire length, so that a corresponding opening 10 is formed for the entry of water.
  • the channel body 4 has two spaced side walls 12, 13 and a closed bottom 14.
  • a substantially closed crosspiece 16 is arranged between the opening 10 and the bottom 14 and is firmly connected to the two side walls 12, 13.
  • this crossbar 16 is integrally connected to the two side walls 12, 13 so that the crossbar 16 is also part of the channel body 4 and is thus made of the same material, preferably concrete, as the rest of the channel body 4, the material being added can be adapted to the requirements, for example with regard to tightness and corrosion resistance.
  • the crossbar 16 forms a stiffening intermediate structure between the side walls 12, 13 for absorbing side forces acting essentially horizontally on the channel body 4.
  • the crossbar 16 forming the stiffening intermediate construction should be arranged as close as possible below the opening 10 or the cover grating 6, so that the stiffening function acts as close as possible to the point of application of the side forces, as a result of which the resulting leverage can be kept low.
  • the upper side 17 of the transverse web 16 facing the opening 10 of the channel body 4 or the cover grating 6 lying thereon is concavely shaped in cross section, as can be seen in FIGS. 1b and 1c.
  • a drainage opening 18 is formed in the crosspiece 16, which separates the space between the opening 10 and the upper side 17 of the crosspiece 16 with one between the crosspiece 16 and the bottom 14 formed cavity 20 connects.
  • the crosspiece 16 or its top 17 are formed such that the top 17 of the crosspiece 16 has a slope on both sides of the drainage opening 18 in the longitudinal direction of the channel element 2.
  • the drainage opening 18 preferably has a circular cross section.
  • the bottom 14 of the channel body 4 should be arranged such that a slope is also formed there, but only in one direction, for example to the left according to FIG. 1 a, in order to lead the water collected there out of the channel element 2.
  • the cavity 20 between the cross piece 16 and the bottom 14 of the channel body 4 is circular in cross section.
  • a tube 22 is inserted in the channel body 4, which extends in the longitudinal direction of the channel element 2 and delimits the cavity 20.
  • the use of such a tube 22 is particularly advantageous if the channel body 4 is made of cast material such as concrete by means of molding; in such a case, the tube 22 can namely be introduced into the mold for casting the channel body 4 as a so-called “lost mold” for forming the cavity 20.
  • the tube 22 is preferably made of plastic and in particular can also consist of different plastics.
  • the tube 22 protrudes a little from one end face 2a (left according to FIG. 1a) of the channel element 2, this tube end 22a having the same diameter as the rest of the tube 20.
  • the other (according to FIG. 1a right) end 22b of the tube 22 is flush with the other end face 2b of the channel element 2 and its diameter is widened to accommodate a sealant, not shown, in the manner of a sleeve, so that one tube end 22a of one Channel element can be plugged into the other tube end 22b of an adjoining channel element and its outer surface lies against the inner surface of the other tube end 22b of the next channel element.
  • sealing elements such as O-rings can also be used.
  • a joint 24 extending laterally to the longitudinal extent of the gutter body 4 for subsequent sealing is formed on the upper side 17 of the transverse web in order to create a liquid-tight connection with the upper side of the transverse web of a next gutter element adjoining at the end.
  • the individual channel elements are connected in series on the end face, as shown in FIG. 2.
  • gutter elements are connected at the rear, which differ in their dimensions from one another in such a way that the distance between the top 8 and the bottom 14 over the longitudinal extent of the entire gutter strand in the flow direction continuously enlarged. Since both the space formed between the top 8 and the crosspiece 16 and the cavity 20 each remain constant in height, the thickness of the crosspiece 16 consequently increases from channel element to channel element (from right to left according to FIG. 2).
  • FIG. 3 shows the same longitudinal sectional view of a channel element as FIG. 1a.
  • FIG. 4 shows the same longitudinal sectional view as FIG. 2.
  • each channel channel element 2 or 2 ' Since with each individual channel element 2 or 2 'the upper side 17 of the cross bar 16 has a slope on both sides of the drainage opening 18, this flows through in each channel channel element 2 or 2' when the channel channel is assembled (see FIGS. 2 and 4) the cover grate 6 and the opening 10 on the top 8 of the channel body 4 water that has entered along the top 17 of the crosspiece 16 to the drainage opening 18, where it is then drained off to the bottom 14.
  • the water then mixes with the water that comes from the upstream channel elements and then flows through the downstream channel elements, where it is with the there, water derived from the respective drainage openings is mixed until the water collected in this way then emerges at the downstream end (according to FIGS. 2 and 4) of the channel strand and is otherwise discharged.
