Abstract

The invention discloses a foundation pit support structure with tunnels on side walls of foundation pits. The structure comprises a base plate; a first support plate is hinged to one side of the upperend of the base plate; fixed blocks are fixed on one sides of the first support plate and the base plate; second limiting grooves are formed in one sides of the two fixed blocks; first limiting blocks are inserted in the second limiting grooves; first support blocks are fixed on one sides of the two first limiting blocks; one sides of the two first support blocks are rotationally connected with two second support rods; two second support rods on the same side form one set; and the opposite ends of the two second support rods in the same set are rotationally connected with second support blocks. The structure is suitable for temporary supporting of foundation pits with various angles, is stable and short in construction period, cannot damage the side walls of the foundation pits with the tunnels, stably supports the side walls, can be recycled by multiple times to reduce the construction cost and to save construction materials, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of foundation pit support, in particular to a foundation pit support structure with tunnels on the side walls of the foundation pit. Background technique [0002] 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 are adopted for the side wall of the foundation pit and the surrounding environment. It is suitable for the location where the surrounding field is open and there are no important buildings around At present, the common support structures for foundation pit construction include: row-pile support structures with bored piles or reinforced concrete slabs as the main body, underground diaphragm walls, cement-soil walls, deep-mixed cement-soil enclosure walls, high-pressure rotary grouting Pile, SMW construction method, etc. [0003] The patent of CN1081665...
