Description

The utility model relates to hydraulic engineering, namely to hydraulic structures intended to strengthen the banks, dams, channels and surfaces of other objects. In particular, the device can be used in the construction of underwater crossings of pipelines, to protect the supports of bridges, crests of dams and dams from erosion during water overflow, during the construction of canals, ditches and drains. Also, the device can be used to protect ground coatings, for example in road construction.

In the field of hydraulic engineering, various designs of flexible concrete mats (GBM) are known that are used to protect a variety of objects from the effects of water flow. GBMs containing concrete blocks found interconnected in order and in rows with a gap with a monolithic rope found the greatest distribution. Concrete blocks are bilateral truncated pyramids, interconnected along the plane of a common larger base into a single monolithic concrete block.

A number of forces act on the GBM. If, under the influence of the river flow, the horizontal drag force will exceed the total frictional force and the passive resistance force of the soil, then the concrete block will detach from the bottom of the watercourse, twisting and drift of the GBM canvas in the water stream. This phenomenon must be avoided both in the construction and operational periods.

From the description of the utility model according to the patent of the Russian Federation No. 106629 (IPC Е02В 3/12, 07/20/2011), GBM is known that contains concrete blocks interconnected in order and in rows with a gap of a monolithic rope. In a known technical solution, concrete blocks are made with brittle edging that overlaps the gaps between adjacent GBM blocks, which provides a high degree of surface protection. After placing a known GBM on a protected surface, under the influence of external factors, concrete blocks can shift relative to each other, resulting in unnecessary destruction of brittle edging, the gap between adjacent concrete blocks will increase, and therefore the risk of soil washing out from under GBM will increase, the surface protection efficiency will decrease .

The objective of this utility model is to increase the protective properties of GBM.

The technical result provided by the utility model consists in eliminating arbitrary displacements of concrete blocks relative to each other after placing the GBM on the protected surface, while maintaining the simplicity of the construction work technology. The exclusion of arbitrary displacements of concrete blocks of GBM relative to each other prevents the displacement of GBM and an increase in the gap between its concrete blocks, which leads to an increase in the protective properties of GBM.

The technical result is achieved due to the fact that the GBM, containing concrete blocks, interconnected in order and in rows with a gap of a monolithic rope, also contains at least two metal elements partially monolithic in concrete blocks. In this case, partially monolithic metal elements are configured to create a welded joint with an additional common rigid metal element to fix their relative position. Moreover, monolithic metal elements are connected to concrete blocks so that they can withstand at least twice the weight of the concrete block.

In the particular case of performing the GBM, a partially monolithic metal element is made in the form of a plate or corner or channel or rod or bracket.

In another particular case, a partially monolithic metal element has a thickness of from 1.5 mm to 5 mm and a length and / or width of at least 10 mm in its non-monolithic part.

In another particular case, a partially monolithic metal element protrudes above the block surface by no more than 35 mm or is located flush with the block surface or recessed into it.

Also, the technical result is achieved due to the fact that the GBM, containing concrete blocks interconnected in order and in rows with a gap with a monopolized rope, also contains at least two metal plates partially monolithic in adjacent concrete blocks. Moreover, the plates have a thickness of 1.5 mm to 5 mm, the length and width of the non-core part is not less than 10 mm, and the relative position of the concrete blocks is fixed by means of at least one rigid metal element welded to the monofilled plates.

In the particular case of this embodiment, the GBM rigid metal element is a straight or curved rod or plate.

The utility model is illustrated by the following graphic materials.

Figure 1 shows a fragment of the edge of the GBM, a view from below, front and top.

Figure 2 presents a concrete block in section with a monolithic corner.

Figure 3 shows a concrete block in section with monolithic channel.

Figure 4 shows a concrete block with monolithic rod.

Figure 5 presents a concrete block with monolithic bracket.

The utility model is as follows.

In the first embodiment, the GBM contains concrete blocks 1, interconnected in order and in rows with a gap of a monolithic rope 2. The adjacent concrete blocks 1 are partially monolithic metal elements 3. These metal elements 3 are made so that an additional general hard can be welded to them metal element 4. The welded joint 5 provides a fixation of the relative position of the metal elements 3, and consequently of the concrete blocks 1, provided the stiffness of the metal element 4, reliable connection the relationship of metal elements 3 with concrete blocks 1 and sufficient strength of the welded joint 5. Moreover, concrete blocks 1 do not have to be located close to each other, with a sufficient length and rigidity of the metal element 4.

The connection of metal elements 3 with concrete blocks 1 can be considered quite reliable if the monolithic metal elements 3 are connected to concrete blocks 1 so that they can withstand at least twice the weight of concrete block 1. This eliminates the possibility of tearing metal element 3 out of concrete block 1 under the action of the dead weight of concrete blocks 1.

To create the necessary strength of the welded joint 5, a partially monolithic metal element must have a thickness of 1.5 mm to 5 mm and a length and / or width of at least 10 mm in its non-monolithic part.

For partial fixation of the GBM bend, at least two blocks of 1 GBM must be rigidly connected. The more concrete blocks are fixed, the stronger the protective properties of the GBM will be enhanced, due to the fact that it becomes practically impossible to displace the GBM in relation to the protected surface and increase the open space between the GBM blocks.

Due to the fact that the elements 3 are metal and monolithic in concrete blocks 1 only partially, they can be quickly and rigidly connected to each other through an additional common rigid metal element 4 using conventional welding, which eliminates the significant complexity of the installation technology of construction work.

GBM with concrete blocks 1 of the desired shape are manufactured using a forming tool in the form of a base and a cover, in which the connecting rope 2 is laid and fixed. Then the tool is filled with liquid concrete mixture. During manufacture of the GBM, a metal element 3 or a greater number thereof is monolithic in the selected concrete block 1, depending on the specific conditions.

The utility model can be implemented with various options for the execution of metal elements 3.

The metal element 3 is made in the form of a plate of square or rectangular shape (Fig. 1), corner 6 (Fig. 2), U-shaped channel 7 (Fig. 3), rod 8 (Fig. 4), staples 9 (Fig. .5) or another suitable form.

For better adhesion to concrete, it is desirable to leave the lower part of the plate uneven, and to perform the rod or bracket with bends in the lower part.

The choice of these forms of metal elements 3 is due to the fact that the elements of all of the above forms can be both reliably monolithic in concrete blocks 1 and have a free surface of their non-polished part, sufficient to make a reliable welded joint 5.

It is more convenient to the vertical shelf of the corner 6 or channel 7 than to the horizontally located plate to weld at an angle a rigid metal element 4, which is difficult to bend in case of its large thickness. The shape of the metal elements 3 in the form of a bracket 9 allows you to create a very strong connection, since the rigid metal element 4 can be pre-passed under the bracket 9, which will take up the main effort to tear the rigid metal element 4, and only then fix it by welding. Rod 8 can be bent to the desired side if necessary.

If a metal element 3, for example, a corner 6 or a rod 8, protrudes above the surface of the block 1 by no more than 35 mm, then its height is sufficient to create a reliable welded joint 5 without excessive consumption of metal.

After completion of welding work, it is advisable to cut off the excess protruding part of the plate, corner, channel or rod, otherwise floating objects will cling to the GBM. Cutting off the protruding parts of the metal element 3 is not required if it is located flush with the surface of the block 1 or recessed into it.

GBM is preferred, in which the concrete blocks 1 are interconnected in order and in rows with a gap of a monolithic rope 2, and metal plates 3 are partially monolithic in adjacent concrete blocks 1. Moreover, the plates have a thickness of 1.5 mm to 5 mm, length and the width of its non-monolithic part is not less than 10 mm, and the relative position of the concrete blocks is fixed by means of at least one rigid metal element 4 welded to the monolithic plates 3.

The plate 3 of the indicated size is firmly held in the concrete block 1 and at the same time is well suited for welding the end of the rigid metal element 4 to it, having a sufficient surface area to create a durable welded joint 5.

The rigid metal element 4 is preferably a straight or curved rod or a thick plate.

The performance of the GBM according to any of its options does not limit its flexibility during transportation, as well as laying on a protected surface, and allows, after laying, when the GBM has taken its working position, repeating the shape of the protected surface, to fix the relative position of concrete blocks, their mutual bending, to exclude arbitrary displacements of concrete blocks relative to each other. In addition, in the case of monolithic metal elements in the corner concrete blocks of GBM, these metal elements can be used to bond two or more GBM to each other.
