The invention relates to auxiliary devices used in the construction of supporting structures of bank protection, built in trenches under the protection of a thixotropic solution.

The purpose of the invention is to increase the reliability of operation by protecting the trench from collapsing. ;

FIG. Figure 1 shows the fence of a trench to be excavated under the protection of a trench to accommodate a supporting structure, vertical section figure 2 is the same, top view; on fig.Z - section aa on fig.15 on figure 4 - trench fencing, axonometrics.

The fence of the trench, protected by mortar, to accommodate the supporting structure, includes fixed side 2 and edge 3 shields located along the edges of trench 1. Fixed end shields 3 are made in the form of vertical knobs 4 connected to each other. The fence is provided with containers 5 placed on the surface of the trachea and communicated using channels 6 with fixed face shields 3. The total volume of containers 5 is appointed not less than the volume of the earth-moving body.

In addition, the fence of trench 1 is equipped with retractable face 7 and side 8 shields installed with the possibility of vertical movement. The lateral end shields 7 have a vertical perforation 9 located opposite the gaps between the vertical rods 4 fixed end shields 3. The bottom 10 of the channels 6 is inclined towards the fixed end shields Z I fixed shields 2

equipped with guiding devices - MI 11, installed with the possibility of interaction with the sliding side shields 8. In addition, the end sliding boards 7 can be equipped with stops 12, installed with the ability to interact with the earth-moving body 13.

The fence of the trench excavated under the protection of the mortar to accommodate I of the supporting structure functions I as follows.

Before starting the digging trench 1 on the surface of the soil set

5 fencing, consisting of fixed side 2 and end 3 shields. The latter are made in the form of vertical stitches 4, which are interlocked, connected to each other. At the same time, containers 5, channels 6 connecting tanks 5 with fixed face shields 3 (and the bottom 10 of the channels 6 are inclined towards the face shields 3), and retractable butts 5 and side 8 shields, are installed at the same time. a vertical perforation 9 located opposite the gaps between the vertical rods 4 of the fixed face shields 3,

0 On fixed side panels 2, guide devices 11 for retractable panels 8 are fastened.

In addition, on the outboard end shields 7, if necessary, stops 12, Tanks 5 are filled with thixotropic solution 14, and then proceed to digging trench 1.

When excavating a trash of a 1 portion of soil with a 13 digixotropic solution of earth moving body 14, which fills containers 5, through channel 6 through the gaps between the vertical rods I

n 4, forming a fixed end pshty 3, and vertical perforation 9 vivizhnyh end shields 7 pere-. It penetrates into the cavity formed during excavation. Thereafter, the vacant containers 5 are refilled with a ticotropic solution H, the sliding shields 7 and 8 are buried in the ground (for example, by acting on the stops 12 by the earth moving body 13) and proceed to the excavation of the trench 1 of the next portion of soil.

After excavating each portion of soil in containers 5, replenish the supply of thixotropic solution 14, and the sliding shields 7 and 8 protect the walls of trench I in its upper part from collapse due to fluctuations in the level of thixotropic solution 14 when removing the earth moving organ 13 .

Claims (2)

1. Fencing of trenches digged under the protection of the solution to accommodate the supporting structure, including fixed lateral and end shields located along the edges of the trench combined into a duct, the dimensions of which Fig five ten 15 20 25 installed in the size of the earth moving excavator, characterized in that, in order to increase reliability by protecting the trench walls from collapsing, it is equipped with containers placed on the trench surface, communicated with channels with face shields, and retractable face and side shields, mounted inside the box with the possibility of vertical movement, while the fixed end shields are implemented in the form of vertical rods connected in between, connected end shields s have a vertical perforation located opposite the gaps between the vertical rods of the fixed face shields, and the bottom of the channels has an inclination towards the latter, and the fixed shields are provided with guides for mounting the shields 2. The fence according to claim 1, characterized in that the sliding shields are provided with stops installed with the possibility of interaction with the earth-moving body. P  ./ - (.
