Description

Technical Field

[0001] This invention relates to the field of substation civil construction technology, and in particular to a foundation pit support device for substation civil construction. Background Technology

[0002] In substation construction, the structure of deep foundation pit support is quite diverse. Deep foundation pit support refers to the measures taken to support, reinforce and protect the sidewalls and surrounding environment of deep foundation pits in order to ensure the safety of underground structure construction and the surrounding environment.

[0003] In the construction of substation civil engineering foundation pits, the inner wall of the pit bears the main pressure due to the 90-degree angle between the inner wall and the bottom wall. Furthermore, we know that the pressure on the pit sidewall varies under different geological and environmental conditions. Therefore, ensuring the stability of the foundation pit support is crucial, especially when the support devices are arranged in a straight line. Since the width of the entire support device is much greater than its length, multiple support modules installed in a straight line are prone to uneven stress distribution. This can lead to horizontal displacement of the support modules during the support process. The baffles of adjacent support modules may be squeezed due to displacement, potentially causing one baffle to be squeezed out, resulting in collapse and affecting the substation construction schedule. Therefore, considering the importance of the stability of the straight distribution of the baffles in maintaining the stability of the support device, we propose a foundation pit support device for substation civil engineering construction, realizing a stable substation foundation pit support device with a positioning structure. Summary of the Invention

[0004] The purpose of this invention is to provide a foundation pit support device for substation civil construction, realizing a stable substation foundation pit support device with a positioning structure.

[0013] Preferably, the inclined end surface of the reinforcing plate is provided with a guide strip, the cross section of the guide strip is in the shape of an isosceles trapezoid structure, and the V-shaped tip of the baffle strip coincides with the short side horizontal part of the guide strip.

[0014] Preferably, the bottom end of the reinforcing plate is connected with a conical seat, and the bottom end horizontal surface of the conical seat is located below the bottom end horizontal surface of the baffle plate.
