Abstract

The invention discloses an assembling type recyclable deep foundation pit support system and a construction technology thereof. The support system comprises one type selected from an assembling frame,a plurality of wood planks, a plurality of base plates, a plurality of anchor heads, a plurality of anchor rods and a plurality of anchor cables, wherein the assembling frame is composed of a plurality of standard frame units, a plurality of side frame units and a plurality of angle frame units; and the anchor rods or the anchor cables fix the standard frame units, the side frame units and the angle frame units on the side walls of a foundation pit through anchor rod connecting holes or anchor cable connecting holes in the base plates and the anchor heads on the outer sides of the base plates. The invention further provides the construction technology. The support system assemblies and combines profile steel and the wood planks to realize the purpose of the deep foundation pit soil body support; the assembling process is environmental-friendly, free of pollution, convenient and fast and shortens the project time limit; the assembling components are simple and cheap, and the material can be recycled, so that the construction cost is effectively reduced, environmental protection is facilitated, and the problem that the material of the existing deep foundation pit support system cannot be recycled is solved.

Description

technical field [0001] The invention relates to a foundation pit support system, in particular to an assembled recyclable deep foundation pit support system, and also relates to a construction process of the assembled recyclable deep foundation pit support system. Background technique [0002] With the rapid development of social economy, buildings are built higher and higher, and the corresponding foundation pits are getting deeper and deeper. At this time, foundation pit support is inevitable. Traditional foundation pit support forms include soil nails, pile anchors, double-row piles, and ground-connected walls. construction site. 2. After the concrete or mortar is sprayed and poured, maintenance is required, which virtually increases the construction period. 3. As a temporary project, the foundation pit project uses a permanent support method, resulting in a great waste of materials. [0003] The inventor retrieved the following relevant patent documents: CN104532856A ...
