The bottoms of the two side protective frames are respectively welded to the tops of the bottom protective frame on both sides. The side protective frames are vertically arranged, and the side protective frames and the bottom protective frame are connected together in a U-shape. The bottom protective frame is placed on the opening of the diaphragm wall trench, and the grid mesh is connected to the side protective frames.
[0007] Preferably, both the bottom protective frame and the side protective frame are constructed by welding multiple square tubes, and the multiple square tubes are spaced apart.
[0008] Preferably, the length of the bottom protective frame is greater than the width of the diaphragm wall groove opening.
[0009] Preferably, the size of the grating mesh is matched with the size of the side guard frame.
[0010] Preferably, the side protective frame is connected with a grid mesh by welding or binding.
[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0012] This utility model discloses a protective device for the opening of a diaphragm wall construction trench. The main material is a square tube, and the side protective frame is welded or tied with a grid mesh. This device has the advantages of small space occupation, safe walking for personnel, and high strength. The device adopts welding connection, which has the functions of simple processing, low cost, convenient operation and relocation, and convenient construction operation. This device greatly improves safety and work efficiency and saves costs. Attached Figure Description

[0018] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0019] like Figure 1-3 As shown, a protective device for the opening of a diaphragm wall construction trench includes a bottom protective frame 1, two side protective frames 2, and a grid mesh 3. The bottoms of the two side protective frames 2 are respectively welded to the top sides of the bottom protective frame 1. The side protective frames 2 are vertically arranged, and the side protective frames 2 and the bottom protective frame 1 are connected together in a U-shape. The bottom protective frame 1 is placed on the opening of the diaphragm wall trench, and the grid mesh 3 is connected to the side protective frames 2.
[0020] Specifically, the bottom of the bottom protective frame 1 is attached to the wall of the diaphragm wall section, allowing personnel to walk on the bottom protective frame 1, while the side protective frame 2 serves to protect personnel safety.
[0021] Both the bottom protective frame 1 and the side protective frame 2 are constructed by welding multiple square tubes, and the multiple square tubes are spaced apart.
[0022] Specifically, the multiple square tubes on the bottom protective frame 1 are spaced close together, with a spacing of 0-5cm, to prevent personnel from falling. The square tubes are of high strength, enhancing the overall structural connection strength and thus better protecting personnel safety. This device has the advantages of safe walking and high strength.
[0023] like Figure 2 As shown, the length of the bottom protective frame 1 is greater than the width of the diaphragm wall groove opening, so that the bottom protective frame 1 can be placed on the diaphragm wall groove opening.
[0024] The size of the grid mesh 3 is matched with the size of the side guard frame 2.
[0025] The side protective frame 2 is connected to a grid mesh panel by welding or binding. The grid mesh panel 3 serves to further protect personnel safety.
[0026] The usage process of this utility model is as follows:
[0027] Based on the dimensions of the diaphragm wall trench opening, the dimensions of the bottom protective frame 1 and the side protective frame 2 are designed, and the bottom protective frame 1 and the side protective frame 2 are welded together in a U-shape. Finally, the bottom of the bottom protective frame 1 of this device is placed on the diaphragm wall trench opening, and personnel can walk on the bottom protective frame. This device improves the safety protection of personnel. This device is easy to move and can be reused.
