Problems solved by technology
[0004] The purpose of the present invention is to provide a deep foundation pit support system and its construction method, which aims to solve the problem in the prior art that reinforcement can only be carried out when the excavation reaches a space where the support plate can be installed. It takes a lot of time from excavation to the completion of slope support. During this process, the slope of the foundation pit is easy to collapse due to lack of support, resulting in technical problems of safety accidents

The invention discloses a deep foundation pit support system and a construction method thereof. By setting out the position of the foundation pit and the positions of the first support ring and the second support ring in advance, the excavation process is carried out while the The first support ring and the first anchor are anchored into the side wall of the foundation pit, and the second support ring and the second anchor are anchored into the side wall of the foundation pit, only the vertical The slide rail exposes the surface of the side wall of the foundation pit, and the support plate is installed through the locking slide block and the bottom clamp, and the support plate always follows the excavation depth during the excavation process. Move to the bottom of the foundation pit, and continuously add the support plate during the moving process, so that the support plate can support the side wall of the foundation pit during the excavation process, avoiding the During the excavation process, the foundation pit began to collapse without enough time to install support, thus avoiding the occurrence of complete accidents during the excavation of deep foundation pits.
Description
technical field [0001] The invention relates to the field of foundation pit support, in particular to a deep foundation pit support system and a construction method thereof. Background technique [0002] At present, the foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit. The support, reinforcement and protection measures adopted for the side wall of the foundation pit and the surrounding environment are used to protect the construction of the underground main structure and the surrounding environment of the foundation pit. Safety, temporary support, reinforcement, protection and groundwater control measures for foundation pits. [0003] The foundation pit support needs to be reinforced while excavating the foundation pit, so that the foundation pit support must be carried out immediately after the foundation pit is excavated for a certain distance. However, in the process of deep foun...
