Hydraulic insert machine and connecting method of foundation pile and steel tube by employing hydraulic insert machine

Abstract

The invention relates to a hydraulic inserting machine and the connecting method of a foundation pile and a steel pipe based on the hydraulic inserting machine which is composed of a base body, a frame body, a telescopic dynamic rod, a hydraulic positioner, a hydraulic coupler, a movable coupler, a vertical adjustment and calibration device and a vertical collimator. The hydraulic inserting machine has high vertical accuracy on the steel pipe insertion and controls the accuracy ranging from 1 / 500 to 1 / 1000L; compared with the general top-down construction, the construction period is reduced by 60%-70%; the energy is saved by 40%; the cost investment is saved by 20%-30%; the connecting method of the foundation and the steel pipe has high vertical accuracy on the steel pipe insertion and controls the accuracy ranging from 1 / 500 to 1 / 1000L; the hydraulic inserting machine has the advantages of rapidness, accuracy, convenience, saving cost and energy, safety and environmental protection.

Description

technical field [0001] The invention relates to a hydraulic insertion machine, and also relates to a method for connecting foundation piles and steel pipes using the hydraulic insertion machine. Background technique [0002] The connection procedures between the pile foundation and the superstructure column (that is, the steel pipe) in the prior art are relatively complicated, and the vertical accuracy of the steel column insertion 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. For the construction of the bored pile,...

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.
