Automatic positioning equipment for underground cover and cut engineering pipe column lower end

Abstract

The invention relates to an automatic positioning device for the lower end of a steel pipe column in underground building and digging construction. The automatic positioning device is formed by the assembly welding of formed steel, forms a crossed conicity and mainly comprises conical guide plates and a positioning four-bladed vane. The four conical guide plates are uniformly distributed on the positioning four-bladed vane around the circumference in 90 degrees, and vertically and fixedly connected with the positioning four-bladed vane. The center of the positioning four-bladed vane is provided with a center point hole, the circumambience of the positioning four-bladed vane is provided with an elevation hole, a positioning bolt hole, a horizontal positioning nut and a foreseen hole for a foundation plate, wherein the conical guide plates realize the delivering function for the steel pipe column, control the verticality of the steel pipe column, and limit the horizontal displacement of the steel pipe column, and the positioning four-bladed vane supports the steel pipe column and controls the horizontal position and the height mark of the steel pipe column. The invention has the advantages that after being arranged on a pile foundation work, the automatic positioning device can realize the functions of delivery, limitation and accurate positioning for the steel pipe column by the construction features, thereby the steel pipe column can be simply, rapidly and accurately installed.

Description

technical field [0001] The invention relates to the installation of steel pipe columns in underground excavation projects, in particular to the positioning and installation of steel pipe columns after pile foundation construction is completed, in particular to an automatic positioning device for the lower end of steel pipe columns. As an auxiliary means for the installation of steel pipe columns, it is suitable for the positioning construction of steel pipe column installation in underground excavation projects, and makes the installation of steel pipe columns simple, fast and accurate.

Problems solved by technology

[0002] At present, the urban space is crowded, and the construction of underground engineering is restricted by the surrounding traffic environment and other factors. After the pile foundation construction is completed, the installation of the steel pipe column becomes an important link. How to accurately connect the steel pipe column to the pile foundation and ensure the verticality of its installation is the focus and difficulty of its construction. The installation of auxiliary means makes the process complicated, takes a long time, and the installation accuracy cannot be guaranteed
