[0002] In foundation pit support, pile rows are a commonly used form of support. Their function is to form an overall support structure by arranging reinforced concrete piles to prevent soil collapse and ensure the stability of the foundation pit.

[0003] It is usually composed of supporting piles, supports (or soil anchors) and anti-seepage curtains. The traditional foundation pit pile support device needs to fix the anti-seepage curtain and supporting piles on the inner wall of the foundation pit, and squeeze and fix the supporting piles through support columns.

The vertical slide 2 is lifted and slidably installed on the plurality of support steel plates 1. When two adjacent support steel plates 1 are clamped with each other, they are just opposite to the slots opened on one side of the lifting slide 2. An extrusion seat 23 is telescopically and slidably installed in the vertical slide 2. An extrusion block 24 that is in contact with the anti-seepage curtain 4 is installed on one side of the extrusion seat 23. The pushed extrusion block 24 can penetrate the vertical slide 2. The plurality of docking components include a plurality of first sliders 25 slidably installed in the vertical slide 2. The plurality of first sliders 25 are elastically installed in There is an extrusion column 28 that interferes with the extrusion seat 23, and a threaded cylinder 29 is installed on the side of the first slider 25 away from the corresponding vertical slider 2. The first slider 25 is connected to the inner cavity of the corresponding threaded cylinder 29, and under the premise that the spring 27 is not squeezed and interfered, one end of the extrusion column 28 is located in the threaded cylinder 29, and the threaded shaft 33 threadedly installed in the threaded cylinder 29 will squeeze and interfere with the extrusion column 28. Several support components 3 include a shaft cylinder 31 and a shaft rod 32 that are threadedly installed in the corresponding threaded cylinder 29 and slidably plugged into each other. An arc block 35 that is squeezed and interfered with the outer rod wall of the shaft rod 32 is telescopically and slidably installed in the inner cylinder cavity of the shaft cylinder 31. The shaft rod 32 is limited and fixed by the arc block 35, so that the shaft cylinder 31 and the shaft rod 32 are limited and fixed.

[0026] Example 2

[0027] Reference Figure 1-4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: a first clamping strip 11 and a second clamping strip 12 are respectively installed on both sides of a plurality of supporting steel plates 1, and a plurality of supporting steel plates 1 are mutually clamped by the first clamping strip 11 and the second clamping strip 12. Figure 2It can be known that strip holes are provided on both sides of the first clamping strip 11, and a strip groove is provided on one side of the second clamping strip 12. When the first clamping strip 11 is clamped with the second clamping strip 12, the strip hole and the strip groove coincide with each other, and the extrusion block 24 is lifted and slidably installed in the strip hole, and is squeezed and abutted in the strip groove to realize the extrusion and fixation of several supporting steel plates 1. The vertical slide seat 2 is provided with a first slide groove 21 on the side away from the corresponding supporting steel plate 1, and the upper groove top and lower groove bottom of several first slide grooves 21 are provided with second slide grooves 22. The first sliders 25 are all slidably installed in the corresponding first slide grooves 21, and the top and bottom ends of the first slider 25 are respectively installed with second sliders 26 slidably installed in the corresponding second slide grooves 22, to ensure that the first slider 25 is always limitedly slidably installed in the first slide groove 21, and several first sliders A spring 27 is provided in each of the first and second sliders 25. One end of the spring 27 is fixedly installed in the first slider 25. An extrusion column 28 is fixedly installed on the other end of the spring 27. The end of the extrusion column 28 away from the extrusion seat 23 is arranged in the inner cylinder cavity of the threaded cylinder 29. The ends away from the shaft cylinder 31 and the shaft rod 32 are both provided with a threaded shaft 33 threadedly installed in the corresponding threaded cylinder 29 and in conflict with the corresponding extrusion column 28. A threaded seat 34 is installed on the outer cylinder wall of the shaft cylinder 31. The arc block 35 is telescopically and slidably installed in the threaded seat 34. The side of the threaded seat 34 away from the shaft cylinder 31 is threadedly installed with a screw 36 rotatably installed with the arc block 35. The screw 36 is rotated to push the arc block 35 to telescopically and slide on the inner cylinder wall of the shaft cylinder 31, thereby squeezing and contacting the outer rod wall of the shaft rod 32, thereby realizing the limited fixation of the shaft cylinder 31 and the shaft rod 32.

[0028] The remaining structures are the same as those of Example 1.

[0029] First, two adjacent support steel plates 1 are clamped together by the first clamping strip 11 and the second clamping strip 12 to form a support wall, and the anti-seepage curtain 4 is placed between the support steel plates 1 and the inner wall of the foundation pit, and the vertical slide 2 is clamped into one side of the support steel plates 1;

[0030] Secondly, the threaded shaft 33 at the ends of the mutually plugged shaft barrel 31 and the shaft rod 32 are threadedly installed in the threaded barrel 29 on one side of the corresponding vertical slide 2. Since the threaded barrel 29 is connected to the inner cavity of the corresponding first slider 25, the threaded shaft 33 threadedly installed in the threaded barrel 29 will squeeze and contact the corresponding squeezing column 28 and compress the corresponding spring 27. The squeezing column 28 that is squeezed and contacted will push the squeezing seat 23 in the corresponding vertical slide 2, so that the two squeezing blocks 24 penetrate the vertical slide 2 and are clamped into the bite of the corresponding first clamping strip 11 and the second clamping strip 12.

[0031] Finally, according to the actual construction environment, the height of the vertical slide 2 is raised and lowered to adjust the vertical installation position of the shaft cylinder 31 and the shaft rod 32, and then the corresponding first slider 25 is slid horizontally to adjust the horizontal installation position of the shaft cylinder 31 and the shaft rod 32. Finally, the screw 36 is rotated to push the arc block 35 to squeeze and contact the corresponding shaft rod 32, so that the shaft cylinder 31 and the shaft rod 32 that are inserted into each other are limited and fixed, thereby realizing the extrusion and fixation of the vertical slides 2 at both ends and several supporting steel plates 1.
