[0002] A diaphragm wall is a foundation project that uses a grooving machine on the ground to excavate a long and narrow deep groove along the peripheral axis of a deep excavation project under the condition of slurry support. After cleaning the groove, a steel reinforcement cage is hoisted into the groove, and then underwater concrete is poured by the conduit method to form a unit groove section. By proceeding in this way section by section, a continuous reinforced concrete wall is built underground as a water cut-off, anti-seepage, load-bearing, and water-blocking structure. During the construction process of the underground wall, it is often necessary to set up a retaining device around the excavated deep groove to prevent personnel from accidentally stepping into the deep groove.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] The present utility model provides a construction retaining structure for diaphragm walls as shown in Figures 1 to 4 which includes a support bottom plate 1. A support block 11 is fixedly connected to the side of the support bottom plate 1. A plug rod 12 is fixedly connected to the lower end of the support block 11. Two groups of support structures 2 are fixedly connected to the upper side of the support bottom plate 1. The support structure 2 includes a first fixing rod 21, a positioning groove 22, a second fixing rod 23, and a third fixing rod 24. The positioning groove 22 is opened inside the first fixing rod 21. The second fixing rod 23 is slidably connected to the positioning groove 22. The third fixing rod 24 is fixedly connected to the upper end of the second fixing rod 23. A threaded hole 25 is opened at a position near the upper end of the side wall of the first fixing rod 21. A support screw rod 26 is threadedly connected inside the threaded hole 25.

[0031] Among them, during the use process, the two groups of second fixing rods 23 are pulled out upwards, and then the support structure 2 is unfolded to adjust the height of the support structure 2. Then, the support screw rod 26 is screwed clockwise into the threaded hole 25 to support the lower end of the second fixing rod 23. Then, according to the different positions of the protection, the number of support structures 2 is adjusted, and the plug rod 12 is inserted into the soil to fix the support structure 2. The support structures 2 are distributed more densely at the positions where they are easily impacted, and the support structures 2 are distributed farther apart at the edge positions.

[0032] Refer to Figure 1 and Figure 5 , a protection structure is connected between the two groups of support structures 2. The protection structure includes a first metal rod 3, a second metal rod 33, and a clamping block 35. Connecting blocks 27 are fixedly connected to the sides of the first fixing rod 21 and the third fixing rod 24. A connecting groove 28 is opened on the surface of the connecting block 27. The clamping block 35 is stuck inside the connecting groove 28. A first threaded groove 31 is opened at the right end of the first metal rod 3. A first threaded rod 32 is fixedly connected to the left end of the first metal rod 3. Second threaded rods 34 are fixedly connected to both the left and right ends of the second metal rod 33. The second threaded rod 34 at the left end of the second metal rod 33 is threadedly connected to the first threaded groove 31. A second threaded groove 36 is opened on the side of the clamping block 35. The first threaded rod 32 and the second threaded rod 34 at the right end of the second metal rod 33 are both threadedly connected to the second threaded groove 36.

[0033] Specifically, after fixing the support structure 2, the protection structure is fixed between the left and right groups of support structures 2. When the distance between the support structures 2 is relatively long, the second threaded rod 34 at the left end of the second metal rod 33 is threadedly connected to the first thread groove 31, thereby connecting and fixing the second metal rod 33 and the first metal rod 3. Then, both the first threaded rod 32 at the left end and the second threaded rod 34 at the right end are threadedly connected to the clamping block 35. Then, the clamping block 35 is clamped inside the connection groove 28 to fix the protection structure. When the distance between the support structures 2 is relatively close, the second threaded rods 34 at both ends of the second metal rod 33 are directly threadedly connected to the clamping block 35, and then the clamping block 35 is clamped inside the connection groove 28 to fix the protection structure.

[0034] Working principle of the present utility model: In order to improve the support strength of the enclosure structure, the support structure 2 and the metal pipe are used in cooperation to maintain the deep groove, improve the anti-collision strength of the enclosure structure. At the same time, the metal pipe can be freely adjusted according to the distance between the support structures 2, improving the convenience of installation, and achieving the improvement of the support strength while facilitating the disassembly, assembly and carrying of the enclosure structure.
