Supporting device suitable for side wall of foundation layer and construction method

Abstract

The invention discloses a supporting device suitable for the side wall of a foundation layer and a construction method. The supporting device comprises vertical column piles embedded under a foundation pit; the tops of the vertical column piles are fixedly connected with vertical columns; a plurality of supporting device bodies are mounted on the vertical columns in the vertical direction; each supporting device body comprises two trays mounted on the adjacent vertical columns; a motor is fixed to every two trays; each motor drives a driving gear to rotate; each driving gear is engaged with two parallelly-arranged supporting arms; each driving gear drives the two corresponding supporting arms to move relatively when rotating; and spherical hinge structures are arranged at the tail ends ofevery two supporting arms so as to adapt to the inclined and uneven side wall of the foundation pit.

Description

technical field [0001] The invention relates to the related technical field of foundation pit support, in particular to a support device and a construction method suitable for the side wall of a base. Background technique [0002] With the development of our country's social economy and the progress of science and technology, the population density of cities is gradually increasing. As urban population density continues to increase, taller and larger buildings rise. In order to meet the needs of engineering, many scholars at home and abroad have explored the construction methods of foundation pit engineering in the process of building construction. [0003] The construction and support of foundation pit engineering are the key links to ensure the safety and stability of buildings. Temporary support, reinforcement, protection and groundwater control measures are commonly used in internal support foundation pits. The side walls of the foundation pit are reinforced to protect...

AI Technical Summary

Problems solved by technology

[0004] However, the current internal support structure has obvious weaknesses in the construction of the foundation pit. The internal support structure is often used as a temporary support structure for the foundation pit to be poured with reinforced concrete. And consume a lot of manpower and material resources;

[0005] After the foundation pit foundation is completed, the internal support made of reinforced concrete structure needs to be removed during the earthwork backfilling process. Due to the high strength of the internal support structure, it needs to be demolished forcibly, which makes the internal support structure unable to be recycled.

[0006] At present, the construction process of the internal support structure applied to deep foundation pits has a low degree of mechanization, improper environmental protection measures, and cannot adapt to fast-paced and high-quality engineering construction
