[0001] This utility model relates to the field of foundation pit support, and in particular to a connected reinforced foundation pit support structure. Background Technology

[0002] Foundation pit support is a set of measures to support, reinforce, and protect the sidewalls and surrounding environment of a foundation pit in order to ensure the safety of underground structure construction and the surrounding environment. It ensures the stability of the foundation pit, prevents the collapse of the soil on the sidewalls, ensures that the foundation pit can maintain a stable geometric shape during the excavation process and the service life, and provides a safe working space for underground structure construction.

[0003] Currently, foundation pit support typically employs concrete-filled pile support and shotcrete mesh support. However, concrete-filled pile support is relatively cumbersome, while shotcrete mesh support has poor stability and cannot achieve the effect of temporary, rapid, and safe support. It also lacks flexibility when supporting small-area foundation pits. Therefore, we propose a connected reinforced foundation pit support structure to solve the above problems.

A support seat is fixedly connected to the upper surface of the two support plates. Two protective plates are provided on the outside of the support seat. Two positioning grooves are formed on the upper surface of the support seat. Positioning blocks are fixedly connected to the front of each of the two protective plates. Threaded grooves are formed on the front of each of the two positioning blocks. Two threaded holes are formed on the front of the support seat. A fixing screw is threaded to the inner wall of one of the threaded holes. The outer surface of the fixing screw is threaded to the inner wall of the threaded groove. Two reinforcing plates are fixedly connected to the upper surface of the supporting base plate. The back sides of the two reinforcing plates are in contact with the front sides of the two protective plates, respectively. Connecting plates are fixedly connected to the left and right sides of the support seat.

[0007] In a further embodiment, the front ends of the two positioning blocks extend into the interior of the two positioning grooves, and the outer surfaces of the two positioning blocks contact the inner walls of the two positioning grooves.

[0011] In a further embodiment, a plurality of fixing rods are provided below the supporting base plate, and the top end of each fixing rod is fixedly connected to the bottom surface of the supporting base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model, through the support base plate with two support plates and support seats, and the cooperation of positioning blocks and positioning grooves, enables a firm connection between the support seats and the support plates. At the same time, the setting of the support seats will make the connection between adjacent support plates more secure, enhancing the stability of the support plates when supporting the inner wall of the foundation pit.
