A safety-based height adjustment method for going up and down stairs in deep foundation pits

Abstract

The invention relates to a safety-based method for adjusting the height of the stairs in deep foundation pits. For the adjustment interval of the height of the up and down stairs, when the first comparison result exceeds the threshold of the height difference, the processing module generates a safety interval of the suspension angle based on the adjustment interval of the required height of the up and down stairs. When the extreme value of the suspension angle can meet the When the range of the safety interval is within the range, the processing module can generate an execution signal and transmit the execution signal to the adjustment module, and the adjustment module generates an execution action based on the execution signal to act on the mechanical construction module, so that the mechanical construction module adjusts the height of the stairs to the required height. Adjustment interval for stair height to create a second height. During the expansion and contraction process of going up and down the stairs, the suspension angle in the adjustment process is judged, so that the expansion and contraction process will not lead to failure of the suspension part.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and relates to a safety-based height adjustment method for going up and down stairs in a deep foundation pit. 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 provide a space...

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.

At present, the stairs 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 at least there are the following deficiencies: the construction depth of the deep foundation pit is constantly changing, when the depth of the deep foundation pit cannot meet When one of the stairs is installed, it needs to be compensated by the external horse track
