[0002] During construction, it is often necessary to dig deeper foundation pits in the rock and soil layer to build the foundation of the building. These deep rock and soil foundation pits need to be fixed and supported by support structures to prevent the deep rock and soil foundation pits from collapsing and deforming. Chinese patent application number: CN202220279248.6 is a rock and soil deep foundation pit support reinforcement structure that prevents deformation. By setting a fixing component, when using the fixing component to support the support plate, the support frame can be rotated to adjust to a suitable angle, and then the drive ring is rotated to allow the drive ring to thread on the threaded rod to drive the fixing rod to slide in the support frame. The triangular shape on one side of the fixing rod makes it easier to insert the fixing rod into the ground for fixed support, which is very convenient. In the above-mentioned device, the fixing rod is inserted into the ground to support and fix the baffle. The fixing rod is easily tilted due to the pressure of the soil, which causes the baffle to tilt, affecting the support effect of the foundation pit. Utility Model Content
