[0023] Based on the above technical features, the embodiment of the present invention sets a pre-positioning component 3. When it comes to underground continuous wall grooves with different widths, the pre-positioning component 3 can ensure that the two support plates 1 adjust their placement spacing according to the width of their underground continuous wall grooves. The two first movable plates 31 are slidably set in the first movable channel one by one to achieve the distance adjustment between the first movable plate 31 and the bottom support plate, so that the first movable plate 31 is always connected to the support plate 1 to achieve the pre-positioning of the cross plate 2, so as to ensure the stability of the effect when the top support component 4 is operated laterally. Through the setting of the top support component 4, The top support assembly 4 includes a fixed plate 42, a screw rod 43 and two symmetrically arranged second movable plates 41. The two second movable plates 41 are slidably arranged in the second movable channel in a one-to-one manner. By rotating the screw rod 43 between the cross plate 2 and the fixed plate 42, the end of the push rod connected to the second movable plate 41 is driven to gradually approach or move away from the screw rod 43. The movement of the push rod drives the two second movable plates 41 to approach or move away from each other in the second movable channel, so that the two second movable plates 41 can respectively abut against the support plate 1, so that the two support plates 1 are tightly pressed against the corresponding underground continuous wall groove wall.

[0024] As some embodiments of the present invention, Figure 1 to Figure 2 As shown, each first movable channel includes two spaced-apart grooves, which are respectively arranged at the upper and lower ends of the horizontal plate 2, and the vertical section of the first movable plate 31 is in the shape of an I. The horizontal plate 2 also includes two symmetrically arranged first connecting plates 21, which are arranged at the top of the horizontal plate 2 to fix the first movable plate 31, and the top of each first connecting plate 21 is interspersed with a fastener 211, and the top of each first movable plate 31 is provided with a plurality of threaded holes that match the fastener 211, and the plurality of threaded holes are arranged equidistantly. The first movable channels are respectively arranged at the upper and lower ends of the horizontal plate 2, which means that there are first movable channels at the top and bottom of the horizontal plate 2 for the first movable plate 31 to slide in the channel, and at the same time, the vertical section of each first movable plate 31 is in the shape of an I. This shape design provides good strength and stability for the first movable plate 31, and also helps to reduce the use of materials. At the same time, the first connecting plate 21, the fastener 211 and the threaded hole are arranged. The main function of the first connecting plate 21 is to fix the first movable plate 31. The fastener 211 passes through the top of the first connecting plate 21 and cooperates with the threaded hole on the first movable plate 31 to fix the first movable plate 31. The multiple threaded holes are arranged equidistantly at the top of the first movable plate 31, which helps to ensure that the first movable plate 31 is evenly and firmly fixed, and at the same time enables the first movable plate 31 to be fixed in time after the distance is adjusted.

[0025] As some embodiments of the present invention, Figure 1 to Figure 2As shown, each support plate 1 includes a positioning block 11, which is arranged at the top of the support plate 1 for fixing the first movable plate 31. A sleeve groove 311 is arranged at one end of the first movable plate 31 close to the support plate 1, and the sleeve groove 311 is movably sleeved on the positioning block 11. The positioning block 11 limits the displacement of the first movable plate 31 in the first movable channel through the sleeve groove 311. Through the arrangement of the positioning block 11, a stable and accurate position is provided for the connection between the first movable plate 31 and the support plate 1, so that the first movable plate 31 can be firmly installed on the support plate 1. Among them, the length of the positioning block 11 is equal to the length of the sleeve groove 311, and the width of the sleeve groove 311 is larger than the width of the pre-positioning block 11. This is to reserve space for the positioning block 11 to move when the two support heads 411 are pressed against the support plate 1, further ensuring the stable connection between the first movable plate 31 and the support plate 1.

The top end of the screw rod 43 passes through the horizontal plate 2 and is connected to the hand wheel 47. The hand wheel 47 drives the screw rod 43 to rotate, thereby driving the second movable plate 41 to move in the second movable channel. By rotating the hand wheel 47, the screw rod 43 can be driven to rotate, thereby driving the second movable plate 41 to move in the second movable channel, so that the user can complete the adjustment of the second movable plate 41 by rotating the hand wheel 47, so as to ensure that the supporting head 411 on the second movable plate 41 always provides a stable abutting force for the supporting plate 1.

[0030] As some embodiments of the present invention, Figure 3 As shown, there are multiple anti-collapse units 100, and the multiple anti-collapse units 100 are arranged at intervals along the length direction of the wall 200.
