A deep pit support mechanism

Abstract

The invention discloses a deep pit support mechanism and relates to the technical field of deep pit support. The invention includes a support column, a telescopic mechanism and a power mechanism. There are several installation holes at one end of the support column, and a limit portion is correspondingly provided on the outside of each installation hole, and a pinch plate is installed in rotation in the limit portion; the telescopic mechanism includes a push rod, a push rod The main body of the worm is a worm, one end of the worm is provided with a guide block, the other end of the worm is provided with a connecting block, the guide block is provided with a guide hole, and the guide hole is sleeved on the worm fixed by the other guide block; the connection block is matched and installed on the installation In the hole; the power mechanism includes a housing, a motor and a turbine. The output shaft of the motor fixed on the housing goes deep into the cavity of the housing, and a turbine is installed; the two worms pass through the through holes provided on the housing, and are connected to the turbine. engage. The present invention constitutes the earth pit support mechanism through the supporting column, telescopic mechanism and power mechanism, and has simple structure, convenient installation, convenient disassembly and convenient multiple use.

Description

technical field [0001] The invention belongs to the technical field of deep pit support, in particular to a deep earth pit support mechanism. Background technique [0002] At present, with the development of building construction in the direction of fast pace and high complexity, in the construction of foundation pits, pit-in-pit and group-pit construction widely appear. However, due to the generally tight construction period, it is obvious that the current construction period cannot meet the needs of the current construction period according to the usual construction process. [0003] Underground space is used more and more for construction, and foundation pits are getting deeper and deeper. For the needs of building functions, there are many deep pits in large foundation pits. In the design of the early enclosure, it is generally designed according to the elevation of the previous building and Construction, in the later stage of civil structure construction, the phenomeno...

However, due to the generally tight construction period, it is obviously impossible to meet the needs of the current construction period according to the usual construction process of first deep and then shallow

[0003] Underground space is used more and more for construction, and foundation pits are getting deeper and deeper. For the needs of building functions, there are many deep pits in large foundation pits. In the design of the early enclosure, it is generally designed according to the elevation of the previous building and Construction, in the later stage of civil structure construction, the phenomenon of building function adjustment often occurs, the depth of the original deep pit may not meet its requirements, and the depth of the deep pit is deepened, resulting in the excavation of the original deep pit enclosure certain risks in the process
