Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] refer to figure 1 , shows a schematic structural view of the elevation positioning device for hydraulically inserting steel pipe columns according to the present invention. The elevation positioning device and positioning operation method for hydraulically inserting a steel pipe column of the present invention replace the manual operation of surveyors in the prior art by using a laser sweeper, compared with the existing manual alignment of the positioning points on the steel pipe column through a level instrument, it has the advantages of precision High performance, simple and convenient operation. In addition, the level and the tower ruler are used to determine the positioning height of the elevation, and the target positioning height of the steel pipe is converted and marked on the tower ruler through the level gauge, and the position...

Abstract

The invention relates to an elevation positioning device of a hydraulic inserted steel pipe column and a positioning operation method. The positioning device is arranged on one side of the steel pipe column, and comprises a level gauge, a sliding staff and a laser swinger, wherein the level gauge is arranged on the ground; the erection elevation of the level gauge is larger than target positioning elevation of a positioning point of the steel pipe column; the sliding staff is erected on the ground and is used for calculating corresponding positioning reading of the target positioning elevation on the sliding staff according to the erection elevation of the level gauge, a reading scale of the erection elevation on the sliding staff, and the target positioning elevation; the laser swinger is arranged on the ground, comprises a laser emission port and is used for emitting laser beams and irradiating the laser beams to the steel pipe column after the laser beams are coincided with the positioning reading on the sliding staff. The elevation positioning device of the hydraulic inserted steel pipe column has the characteristics of simple principle, high elevation control precision and the like, and is convenient to implement.

Description

technical field [0001] The invention relates to the field of building surveying, in particular to an elevation positioning device and a positioning operation method for hydraulically inserting a steel pipe column. Background technique [0002] With the development of rail transit, more and more deep foundation pit projects have attracted people's attention. In large-scale deep foundation pit structure engineering, the connection between steel pipe column and underground pile foundation is often used as the vertical support of underground structure. In recent years, the technology of mechanical hydraulic insertion of steel pipe columns has gradually replaced the manual positioning and installation method, and has become a common technology for the installation of large steel pipe columns. [0003] The method of hydraulically inserting the steel pipe column is mainly to precisely position the steel pipe column through the control of verticality, center position and elevation....
