Definitions

  • the present invention concerns a method and device for putting a drain pipe almost horizontally in the ground, whereby a plough is moved through the ground so as to form a ditch, and whereby the drain pipe is put in the ditch and draining material is pressed in the ditch while this ditch is being formed by the plough.
  • Horizontal drain pipes are used in large pipeline works, whereby the pipeline is put 5 to 6 m deep, in order to lower the groundwater level.
  • Such horizontal drain pipes are also used for soil consolidation.
  • chain ditch diggers are often used which dig a ditch of about 30 cm wide, in which the drain pipe is placed. Immediately thereafter, the ditch is filled with sand.
  • the sand in the ditch absorbs large amounts of water from the environment.
  • the drain pipe cannot be placed at a large depth, in particular not deeper than 8 m, for example 18 to 20 m deep.
  • Compressed air or water under pressure are supplied to a closed funnel with powdered material such as sand, which funnel is connected to a ring-shaped chamber surrounding the drain pipe at the bottom of the ditch and provided with a number of mouth pieces directed towards the back via a flexible pipe.
  • powdered material such as sand
  • this casing has a very limited height which is about equal to the width of the ditch which is significantly wider than the drain pipe, so that it is relatively difficult to draw the plough, which has for a result that no deep ditches can be formed.
  • this method cannot be used for ditches of very large depths, for example of 8 m or more.
  • the present invention aims a method for putting a drain pipe almost horizontally in the ground which excludes the above-mentioned and other disadvantages and which makes it possible to provide a drain pipe almost horizontally at a large depth in a simple and fast manner and nevertheless obtain a good drainage.
  • the formed ditch can be quite narrow and nevertheless be filled with sand or other drainage material.
  • the formed screen of sand or other drainage material serves to supply water to the drain pipe and to thus obtain the above-mentioned good drainage.
  • the drainage material can be pressed in the ditch both mechanically by means of a push mechanism and pneumatically or hydraulically by means of fluid under pressure, whereby drainage material is supplied under hydraulic or pneumatic pressure in the ditch at different heights.
  • fluid under pressure is squirted in front of the plough in order to loosen the soil in front of the plough and to reduce the forces on the plough.
  • the present invention also concerns a device which is suitable for applying the above-mentioned method.
  • the present invention concerns a device for putting a drain pipe horizontally in the ground, which device contains a plough, means to move this plough in the ground, means to provide the drain pipe in the ditch formed by the plough and means to provide drainage material under pressure above the drain pipe in the ditch formed by the plough, whereby the latter means contain means to provide the drainage material under pressure over a height which is significantly larger than the width of the ditch.
  • the latter means include a push mechanism which may contain a push element and means to move this push element back and forth.
  • the above-mentioned means contain pipes for the drainage material reaching up to different levels, means to supply drainage material to these pipes and means to pneumatically or hydraulically exert pressure on the drainage material in these pipes.
  • each pipe Under the lower end of each pipe can be provided one or several deflectors directed slantingly backwards.
  • the plough On its front side, the plough may contain a high-pressure pipeline directed from top to bottom which is provided with nozzles directed to the front, and means to supply fluid under pressure to these nozzles.
  • the device represented in figures 1 to 4 contains a caterpillar tractor 1 upon which a reel 2 is provided on one end upon which the drain pipe 3 is wound.
  • a plough 4 is provided on the tractor 1 which consists of a vertical pipe 5 upon which two parallel walls 6 are fixed on the back side and upon which a high-pressure pipeline 7 provided with nozzles 8 is connected by two sidepieces 9 on the front side.
  • this plough 4 is only slightly larger than the diameter of the drain pipe 3, namely only a few centimetres.
  • the depth of the plough 4 is significantly larger and amounts to a few metres, even more than 8 m, and it is for example 18 to 20 m.
  • This plough 4 can be moved up and down in a guide 10 fixed on the above-mentioned back end of the tractor 1.
  • Said plough 4 is strutted on top by means of a prop 11 which is fixed to the top end of the plough 4 on the one hand and to the front side of the tractor 1 on the other hand.
  • the bottom side of the plough 4 can be connected to the front side of the tractor 1 or to a second tractor by means of a cable 12.
  • the top end of the pipe 5 is situated at the height of the shaft of the reel 2.
  • the part of the drain pipe 3 which is wound off the reel 2 extends through this pipe 5 and then backward, under the end of this pipe 5 and between the walls 6 over the bottom of the ditch 13 formed by the plough 4.
  • this drain pipe 3 is fixed to the bottom end of an additional vertical pipe 14 which sticks in the ground where the ditch 13 begins.
  • the high-pressure pipeline 7 is a pipe with a smaller diameter than the pipe 5 which goes somewhat deeper than this pipe 5.
  • the top end of this high-pressure pipeline 7 is connected to a high-pressure hose 15 which is connected to a high-pressure pump 16.
  • the device contains means 17 to provide sand under pressure in the ditch 13.
  • These means 17 contain a funnel 18 on the one hand provided on the back side of the tractor 1, behind the plough 4 and which opens with its lower end in the space between the two walls 6, and a push mechanism 19 on the other hand to mechanically push the freshly supplied sand backward.
  • the latter push mechanism 19 consists of a push element 20 which is provided such that it can be moved between the walls 6 and means to move this push element 20 back and forth in relation to the plough 4.
  • These means consist of a support 21 placed against the pipe 5 and preferably fixed to it, for example by means of welding, arms 22 which are hinge-mounted to the support 21 and which are hinge-mounted to the push element 20, and a push cylinder 23 to rotate the arms 22.
  • the push cylinder 23 Since, when the arms 22 are rotated, the push element 20 also moves in the vertical direction, the push cylinder 23 will be provided between the top side of the pipe 5 and the top end of the push element 20. Naturally, the push cylinder 23 is connected to an oil source under pressure via a control mechanism.
  • an end of the drain pipe 3 is provided through the pipe 5 and fixed to the lower end of the additional pipe 14.
  • a manner which is always applicable consists in putting a rectangular box profile 24 in the ground in which the additional pipe 14 and the plough 4 fit and of which the front side 24A can be removed, as is represented in figures 3 and 4.
  • This box profile is hereby preferably filled with water.
  • this box profile 24 When this box profile 24 is provided at a sufficiently large depth, the front side 24A is pulled out of the ground, and the pipe 14 and the plough 4 are lowered in it.
  • the plough 4 is moved forward through the soil by the tractor 1, but also due to the movement of the push element 20 which lunges out on the ground or on the already provided sand during its backward movement. In weak ground, the back-and-forth movement of the push element 20 alone may be sufficient to move the plough 4 forward.
  • this forward movement is made significantly easier by squirting fluid under pressure through the nozzles 8.
  • a fluid can be used water or air or a mixture thereof. This squirting can be carried out intermittently.
  • the pipe 14 remains in place, i.e. where the ditch 13 begins.
  • sand is pressed in the ditch 13 so that a water guiding screen, namely a sand screen, is formed above the drain pipe 3 which, as the plough 4 moves forward, is wound off the reel 2 and always ends up with a longer part on the bottom of the ditch 13, preferably at a small distance from the ground surface.
  • the ditch 13 can be further filled with soil, preferably soil which is not permeable to air, in particular clay or bentonite.
  • a pump 26 can be provided at the bottom in this pipe 14 with a pressure pipe 27 extending through the pipe 14 to the top of the ground surface.
  • the arms 22 can be replaced by pressure cylinders or even the entire system consisting of the push element 20, support 21 and arms 22 can be replaced by inflatable bellows and means to blow up these bellows and make them deflate again.
  • the embodiment of the device represented in figure 5 differs from the above-described device in that the means 17 to provide sand under pressure in the formed ditch 13 do not contain a push mechanism 19, but pneumatic means.
  • each of these sand pipes 28 are fixed one or several deflectors 29 directed slantingly to the bottom and to the back into which said sand pipes 28 open.
  • the deflectors 29 thus extend between the walls 6 up to almost the back end of these walls 6.
  • a horizontal partition 30 Between the bottom edge of a deflector 29 and the accompanying sand pipe 29 is provided a horizontal partition 30.
  • the compressed air line 33 is connected to an air receiver which is not represented in figure 5, whereas the screw pump 32 is connected to a funnel 34 erected on top of a moveable storage tank 35 mounted on caterpillars.
  • the above-described device and method are particularly suitable for the vacuum consolidation of soil, which is known as such.
  • an air-tight layer 36 of for example one metre thick must be provided above the sand screen in the ditch 13, and the top ends of the pipe 14 and of the drain pipe 3 must be sealed by means of seals 37 and 38 as represented in figure 6.
  • the pressure pipe 27 is connected to the bottom side of a vacuum tank 39 in which is created an underpressure by a vacuum pump 40 erected on top.
  • a suction pipe 41 connected to the top side of the vacuum tank 39 opens in the additional pipe 14 on the one hand and in the end of the drain pipe 3 protruding above the ground on the other hand.
  • a water pump 42 with a non-return valve onto which a delivery hose 43 is connected In the bottom of the vacuum tank 39 is erected a water pump 42 with a non-return valve onto which a delivery hose 43 is connected.
  • the medium in particular water which is collected in the drain pipe 3, is pumped through the pump 26 to the vacuum tank 39, whereby the vacuum helps to collect this medium in the vacuum tank 39.
  • the water level in the ditch 13 is kept low, for example at a depth of 15 m.
