Hanging type construction staircase of deep foundation pit and construction method thereof

Abstract

The invention provides a hanging type construction staircase of a deep foundation pit and a construction method thereof. The hanging type construction staircase is located between two reinforced concrete horizontal supports and comprises a first step section, a second step section and a third step section, wherein the first step section, the second step section and the third step section are connected in a head-to-tail mode to be a Z-shaped structure. According to the hanging type construction staircase of the deep foundation pit, the reinforced concrete horizontal supports in the deep foundation pit engineering are utilized, the staircase is suspended on the supports, the mounting environment of the construction staircase can be greatly expanded, and the use performance is improved; and in addition, the staircase can be lengthened or removed by sections according to the engineering progress, the shortcoming that the site change is large during construction of the deep foundation pit is overcome, and good adaptability is achieved.

Description

technical field [0001] The invention belongs to the field of building engineering construction, and relates to a construction staircase, in particular to a suspended construction staircase for a deep foundation pit and a construction method thereof. Background technique [0002] In modern construction projects, underground structures can be used as functional areas such as parking, equipment, civil air defense, and transportation. With the large-scale development of underground structures, a large number of deep foundation pit projects continue to appear. The construction of deep foundation pit engineering is gradually realized with the excavation of earthwork layer by layer. During the construction period, personnel and materials need to enter the ground layer by layer. [0003] Due to the great variability of the deep foundation pit construction site and the top-down construction, the use of factory-produced shaped stairs is limited. The up and down of personnel generall...

AI Technical Summary

Problems solved by technology

The up and down of personnel generally adopts simple stairs, which are connected by steel pipes of on-site scaffolding. This kind of stairs has a simple structure, but the comfort and safety are relatively poor.

Moreover, construction stairs are generally arranged around the foundation pit, and deep foundation pits are generally excavated in the center area first, and the installation of stairs is seriously lagging behind.
