Description

Technical Field

[0002] Deep foundation pit support refers to the measures of support, reinforcement and protection for 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. The wall formed by spraying concrete on the side facade of the pit wall between two adjacent reinforced concrete supporting piles of the deep foundation pit support structure is called pile protection. The existing technologies for pile protection are: first hang steel mesh externally and then spray concrete. When the soil between the supporting piles in the deep foundation pit support structure is in a moist state, that is, the soil between two adjacent supporting piles below the groundwater level and affected by groundwater, the pile protection formed by spraying concrete freezes and thaws in the winter season, and the cycle shows large-scale stratification, agglomeration, shedding and hollowing. The pile protection formed by spraying concrete suffers devastating damage, and the pile protection at this time does not play the role of pile protection.

[0003] However, in the existing deep foundation pit supporting structure, the hanging plates are inconvenient to disassemble and install during connection, which causes certain difficulties for construction workers. In addition, the connecting device of the hanging plates in the existing deep foundation pit supporting structure is not equipped with a good thermal insulation device when connecting the hanging plates, which reduces the service life of the hanging plates to a certain extent. In addition, the connecting device of the hanging plates in the existing deep foundation pit supporting structure is not stable enough after connection, which affects the use of the deep foundation pit supporting structure.
