A Safety-Based Adjustment Method for the Hanging Angle of Up and Down Stairs in Deep Foundation Pit

Abstract

The present invention relates to a safety-based method for adjusting the suspension angle of up and down stairs in a deep foundation pit, comprising: a processing module acquires a stress-strain signal monitored by a monitoring module installed in the suspension part and generates a stress equivalent, and when the stress equivalent exceeds a certain In the case of stress, the processing module can generate an execution signal and transmit the execution signal to the adjustment module, and based on the execution action generated by the adjustment module according to the execution signal, the mechanical construction module can adjust the movement of going up and down the stairs. The height adjusts the suspension angle formed by the suspension part and the up and down stairs, so that the up and down stairs can be safely installed in the inner space of the deep foundation pit when the stress equivalent exceeds the allowable stress . The up and down stairs are made into a stretchable structure. Based on the stress monitoring of the suspension part, when the stress reaches the allowable stress, the suspension angle can be adjusted to reduce the stress value of the suspension part to ensure construction safety.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and relates to a safety-based method for adjusting the hanging angle of stairs going up and down deep foundation pits. Background technique [0002] With the continuous advancement of green construction, safe and civilized construction, the implementation of the national development strategy on strengthening energy conservation and emission reduction, and the construction of a resource-saving and environment-friendly society, green and environmentally friendly construction of construction projects is gradually being promoted. A foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane size. Building foundation pit refers to the space below the ground excavated for the construction of building (including structure) foundation and basement. The foundation pit is a temporary project, and its function is to provid...

AI Technical Summary

Problems solved by technology

It mainly has the following defects: the disassembly process is cumbersome, labor-intensive and time-consuming; there is no safety protection device; the reuse rate is low, material waste, etc.

[0014] Through the investigation of the existing technology, it is found that the stairs used as the upper and lower deep foundation pits are installed layer by layer according to the depth of the deep foundation pit and cannot be retracted, so there are at least the following deficiencies: the depth of the deep foundation pit construction is constantly changing , when the depth of the deep foundation pit cannot meet the requirements of installing one of the up and down stairs, it needs to be compensated by the external horseway
