[0002] Deep foundation pit support refers to the measures of support, reinforcement and protection of the side walls of deep foundation pits and the surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit. In the support of deep foundation pits, trenches are usually opened on the edges of the side walls around the bottom of the deep foundation pit, and the baffles supporting the side walls of the foundation pit are inserted into the trenches, leaving a certain gap between the baffles and the side walls of the foundation pit, and then the baffles are supported in the deep foundation pit by inclined support rods. After the baffles are fixed, concrete is poured between the baffles and the side walls of the deep foundation pit to form a stable support body, so as to achieve the effect of supporting the side walls of the deep foundation pit.
