Description

Technical Field

[0001] The present application relates to the technical field of construction foundation pit protection devices, and in particular to a construction earth excavation foundation pit protection device. Background Art

[0002] The foundation pit is a soil pit excavated at the foundation design position according to the base elevation and foundation plane dimensions. When the construction depth of the foundation pit reaches 2m, it poses a danger to operations at the pit edge. According to the regulations on high-altitude operations and edge operations, edge protection facilities should be set up and protective railings need to be set up around the foundation pit.

[0006] A protective device for foundation pit excavation during construction includes two vertical columns and a protective plate. Two circular rings are fixedly installed on the outside of the vertical columns. Several limiting columns are fixedly installed in a circular shape on the upper ends of the circular rings. Two connecting blocks are fixedly installed on both sides of the protective plate. A sleeve is fixedly installed on one end of the connecting block, and the sleeve is engaged with one of the limiting columns for limiting.

[0007] Preferably, two reinforcement frame plates are fixedly installed at the rear end of the protective plate, a resistance plate is fixedly installed near the middle position inside the reinforcement frame plate, and a rotating column is movably installed near the bottom end inside the reinforcement frame plate, and a movable plate is fixedly installed outside the rotating column.

[0008] Preferably, a fixed plate is fixedly mounted on one side of the movable plate, and two bolts are threaded through one side of the fixed plate.

[0009] Preferably, the lower portion of the abutment plate abuts against the inclined plate, and a threaded hole is provided at one end of the inclined plate.

[0010] Preferably, one side of the inclined plate is fitted with the fixed plate, and the bolts are threadedly connected to the threaded holes.

[0011] Preferably, a disc is fixedly mounted on the lower end of the vertical column, and conical fixing members are fixedly mounted on the lower ends of the disc and the protective plate.

[0012] In summary, the present application has the following beneficial technical effects: by providing a circular ring, the sleeves on both sides of the protective plate are inserted from above the appropriate limiting posts, so that the protective plate and the two vertical posts are limited, and multiple limiting posts are provided on the circular ring, which facilitates the insertion of the sleeves from multiple angles. This design method can provide integrated protection for foundation pits at different angles or corners of foundation pits, thereby improving the quality of protection, and the installation of the protective plate is relatively convenient, and only the spacing between the two vertical posts needs to be controlled;

[0013] After installing the protective plate, refer to Figure 3 The movable plate is set up so that it contacts the ground to support the protective plate, and the reinforced frame plate also increases the strength of the protective plate and the strength of the protection.
