Method for constructing steel pipe upright pile through semi-reversed-construction method

Abstract

The invention discloses a method for constructing a steel pipe upright pile through a semi-reversed-construction method. The method includes the following steps of firstly, locating the pile position; secondly, embedding a long pile casing; thirdly, drilling the upright pile; fourthly, placing an adjusting frame; fifthly, placing a reinforcement cage; sixthly, splicing an upright pile steel pipe with a tool pipe; seventhly, placing the upright pile steel pipe and the tool pipe; eighthly, finely adjusting the upright pile steel pipe and the tool pipe; ninthly, placing a concrete pouring and tamping frame; tenthly, pouring concrete into the upright pile; and eleventhly, pulling out the tool pipe. According to the method, the independently-studied-and-created hoisting tool pipe and the whole vertical detection device are utilized, so that construction quality, the construction schedule and construction safety are guaranteed, construction cost is reduced greatly, and the method has a great significance in development of semi-reversed method construction.

Description

technical field [0001] The invention relates to a construction method of a steel pipe column pile by a semi-reverse method, and belongs to the technical field of building construction. Background technique [0002] With the rapid development of domestic urbanization, the space between buildings in the urban core area is getting smaller and smaller, the construction site is narrow, and the buildings and surrounding environment are also very sensitive to settlement deformation. At this time, a "reverse method" construction New technologies are gradually being used and matured. In the "upside-down method" construction, the upper horizontal support load structure is transmitted, and the vertical support structure of a support column and a single support pile at the bottom is usually adopted, referred to as "one column and one pile". The conventional method of constructing steel pipe column piles (that is, one column and one pile) is to use a pile inserting machine. This machine...

AI Technical Summary

Problems solved by technology

The conventional method of constructing steel pipe column piles (that is, one column and one pile) is to use a pile inserting machine. This machine is expensive, and the number of domestic machines is limited, which cannot meet large-scale mass production; and this machine requires a large pile diameter and a pile top elevation of Ground, long construction period, etc.
