Description

Lifting equipment for foundation pit construction and use method Technical Field The application relates to the technical field of foundation pit construction, in particular to foundation pit construction lifting equipment and a use method thereof. Background In deep foundation pit engineering construction, the Z-shaped safety ladder cage has become a preferred scheme of a vertical transportation channel by virtue of the excellent safety performance and moderate gradient design. However, the installation and disassembly operations of the traditional Z-shaped ladder cages still mainly depend on large hoisting equipment configured on the pit roof. In the traditional installation process, the automobile crane needs to be stopped at the edge of the foundation pit, and the standard section of the ladder jack in the basket is lifted to a designated position in the foundation pit through a lifting hook and a steel wire rope system. Then, the operator needs to manually guide and position on the aerial working platform, and fix the new standard section with the installed part by adopting a bolt or a bolt connection mode. The process has extremely strong dependence on large equipment, and requires constructors to perform high-altitude assembly operation in the foundation pit. The main technical bottlenecks are manifested in the following aspects: 1. the space limitation conflicts with equipment, namely, in a foundation pit construction site with limited working face, large hoisting equipment often faces the problems of difficult approach, limited station, inconvenient deployment and the like. Meanwhile, the ladder cage installation operation occupies the resources of core vertical transportation equipment such as a tower crane, and other construction procedures are forced to be interrupted, so that the overall construction progress is seriously affected. 2. The potential safety hazard in the installation process is prominent, the standard knot in the suspension state is easy to swing greatly, and the risk of collision with the foundation pit supporting structure or the installed ladder cage exists. The operators lack a stable operation platform during high-altitude operation, and are faced with double safety threats of high-altitude falling and object striking during assembly and connection operation. 3. The installation accuracy and the efficiency are low, the positioning adjustment is carried out by completely relying on the manual experience and the cooperative coordination of a signal worker and an operator, the installation accuracy is difficult to ensure, the time and the labor are wasted in the alignment process, and the installation period is obviously prolonged. 4. The problem of foundation pit side slope additional load is that when large hoisting equipment works in a pit edge area, the requirement on the bearing capacity of the foundation is high, and engineering risks such as ground subsidence or side slope stability reduction can be possibly induced.
