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

Embodiment 1

[0062] This embodiment provides a safety-based method for adjusting the hanging angle of stairs going up and down deep foundation pits. In the case of no conflict or contradiction, the whole and / or part of the content of the preferred implementations of other embodiments may serve as supplements to this embodiment.

[0063] The method includes:

[0064] S1: The processing module 5 acquires the stress and strain signals monitored by the monitoring module 9 installed in the suspension part 4 and generates stress equivalents. In the event that the stress equivalent exceeds the allowable stress, the processing module 5 can generate an execution signal and transmit the execution signal to the regulation module 7 .

[0065] S2: An execution action based on the signal generation performed by the adjustment module 7 . The mechanical construction module 8 adjusts the suspension angle θ formed by the hanging part 4 and the up and down stairs by adjusting the height of the up and down ...

Abstract

The invention relates to a safety-based method for adjusting the hanging angle of an upper stair and a lower stair of a deep foundation pit. The safety-based method for adjusting the hanging angle ofthe upper stair and the lower stair of the deep foundation pit comprises the following steps that a processing module acquires stress and strain signals monitored in a monitoring module arranged at ahanging part and generates stress equivalent; and under the condition that the stress equivalent exceeds allowable stress, the processing module can generate an execution signal and transmit the execution signal to an adjusting module; an execution action is generated based on the execution signal of the adjusting module, a mechanical structure module adjusts the hanging angle formed by the hanging part and the upper stair and the lower stair by adjusting the height of the upper stair and the lower stair, so that the upper stair and the lower stair are safely installed in the inner space of the deep foundation pit under the condition that the stress equivalent exceeds the allowable stress. The upper stair and the lower stair are manufactured into a telescopic structure, based on the stressmonitoring of the hanging part, when the stress reaches the allowable stress, the hanging angle can be adjusted to reduce a stress value of the hanging part to ensure the 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...
