Hydraulic vertical insertion machine and method for connecting foundation pile and steel pipe column

Abstract

The invention relates to a hydraulic vertical insertion machine. The hydraulic vertical insertion machine comprises a seat body and a first hydraulic vertical insertion device arranged on the seat body, and is characterized in that the seat body is provided with a platform on which a second hydraulic vertical insertion device is arranged; the first hydraulic vertical insertion device and the second hydraulic vertical insertion device are sequentially arranged along the axial direction of the seat body; the first hydraulic vertical insertion device is arranged below the second hydraulic vertical insertion device; and the first hydraulic vertical insertion device and the second hydraulic vertical insertion device can independently or synchronously rotate 360 degrees to regulate the verticality of a steel pipe column. The hydraulic vertical insertion machine can effectively control the up-floating of the steel pipe column and ensure the vertical precision of inserting the steel pipe column. Compared with the conventional reversed construction method, the invention has the advantages of short construction period, saved energy resources and saved cost investment. The invention discloses the hydraulic vertical insertion machine and a method for connecting a foundation pile and a steel pipe column.

Description

technical field [0001] The invention relates to a hydraulic vertical insertion machine, and also relates to a method for connecting foundation piles and steel pipe columns using the hydraulic vertical insertion machine. Background technique [0002] The connection procedures between the pile foundation and the superstructure column (that is, the steel pipe column) in the prior art are relatively complicated, and the vertical accuracy of the insertion of the steel column is not high. [0003] Such as the patent No. 02136208.4 announced by the National Patent Office, the specific construction process is: 1. The production of the hoisting base: in order to bear the weight of the steel member of the column, a reinforced concrete base is made around the pile position; 2. The completion of the steel column member Manufacture and transport to the construction site, butt the full length of the steel column to be installed, and set the electric level probe on the top of the pile; 3. ...

AI Technical Summary

Problems solved by technology

The controllability of the above-mentioned patents is poor. If the first attempt is unsuccessful, the setting time for the second insertion of concrete is not allowed. In addition, after the steel column is sealed, the buoyancy is very large, and it is difficult to insert only by its own weight. The positioning is cumbersome and it is difficult to ensure the construction quality.

In addition, the steel casing must be lowered to the bottom, so the safety of workers cannot be guaranteed when they go down the well. Repeated pouring of concrete wastes material energy, and the construction period is as long as 10 to 20 days.
