Embodiment Construction

[0035] A small foundation pit channel steel support frame support construction method, the steps include:

[0036] The person in charge of the on-site technology studies the construction drawings, prepares a special construction plan according to the soil conditions on the site, the number and size of the foundation pit, arranges the construction sequence reasonably, increases the reasonable turnover times of the support frame, reduces the investment, and reduces the project cost. Cost, while ensuring the speed of foundation pit construction, speed up the construction period.

[0037] 1. Determine the materials used. According to the size and depth of the foundation pit design, calculate the lateral pressure and water pressure of the foundation pit soil, and then determine the material and size requirements for the channel steel support frame.

[0038] 2. Processing and manufacturing materials: According to the calculated requirements of the materials used, the channel steel, ...

Abstract

The invention belongs to the technical field of building construction, and particularly relates to a construction method for supports of a box iron supporting rack of a small foundation pit. Supporting of the small foundation pit can be implemented. The construction method for the supports of the box iron supporting rack of the small foundation pit comprises the following steps of machining the box iron supporting rack of the foundation pit in advance according to the size of the foundation pit; timely hoisting the supporting rack into the foundation pit after the foundation pit is excavated; hoisting the rack out of the foundation pit by using a crane after foundation construction is finished; performing construction of a next foundation; and detaching and recycling box iron and steel plates after overall construction is finished. The construction method for the supports of the box iron supporting rack of the small foundation pit has the advantages of convenience in construction, easiness in machining and manufacturing and high recyclability. Engineering construction cost can be saved effectively, and construction progress is accelerated. The construction method for the supports of the box iron supporting rack of the small foundation pit is environment-friendly and has wide application prospects and wide application markets.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a support construction method for a channel steel support frame body of a small foundation pit. Background technique [0002] In building construction, there are large-scale and small-scale foundation constructions. Some small independent foundations generally have an area of ​​less than 50 square meters. In order to ensure the smooth progress of precipitation and construction, it is often necessary to carry out large-scale excavation first, and carry out precipitation and support in the surrounding area. Not only the construction period cannot be guaranteed, but also the cost of excavation and backfilling is increased, which makes the project cost and The construction period is affected, and the traditional concrete support pile is adopted, which has a long construction period and high cost. At present, when constructing independent foundation pits wit...
