High verticality holding pressure static pile driver

Abstract

A high verticality hugging type static pressure pile driver relates to the technical field of pile foundation construction and solves the technical problem of improving the verticality of pile formation. The static pile driver includes a road base, a pile machine base, an upper support clamp frame, and an orifice casing; the road base is equipped with left and right centering adjustment seats, and the left and right centering adjustment seats are equipped with front and rear centering adjustment seats. The base of the pile driver is installed on the front and rear centering adjustment seat through the leveling oil cylinder, and the vertical guide column is fixed on the base of the pile driver; the guide column is equipped with a pressure column clamp frame that can slide up and down, and the upper support clamp frame is fixed on the top of the guide column , the orifice casing is installed at the orifice of the pile hole, and its body is inserted into the pile hole. There are multiple lower supports in the orifice casing; two-point support is realized through the upper support clamp frame and the lower support, and the The column clamp frame applies static pressure to the pile. The static pressure pile driver provided by the invention has high alignment accuracy and good alignment efficiency.

Description

technical field [0001] The invention relates to pile foundation construction technology, in particular to the technology of a high verticality holding pressure type static pressure pile machine. Background technique [0002] Static pressure pile construction uses a tight cylinder to hold the pile tightly. The self-weight of the machine and the counterweight on the fuselage are transmitted to the pile body through the top pressure cylinder. After concentrated force, the pile is pressed into the formation mark. high school. The accuracy of the pile position and the verticality control of the pile are the key to the quality of the pile driving. The stakes are generally adjusted after being pressed in 30-50cm. However, the general holding pressure pile driver adopts one or two pile holding points at the same time. When the pile column is longer, the pile verticality of existing pile pressing equipment is relatively poor, usually only about 1 / 200. At the same time, the existi...

AI Technical Summary

Problems solved by technology

However, the general holding pressure pile driver adopts one or two pile holding points at the same time. When the pile column is longer, the pile verticality of the existing pile pressing equipment is poor, usually only about 1 / 200

At the same time, the existing static pressure pile machine adopts pipe walking or walking alignment when aligning the pile position, the equipment is huge, and the alignment accuracy is poor, and the alignment efficiency is also low
