Steel pipe pile foundation and construction method thereof

Abstract

The invention provides a steel pipe pile foundation. The steel pipe pile foundation comprises an upper section pile and a lower section pile which are arranged in a butt joint mode; a lining ring is arranged at the joint of the upper section pile and the lower section pile, the lining ring is placed on the inner wall of the lower section pile, and the outer wall of the lining ring abuts against the inner wall of the upper section pile and the inner wall of the lower section pile at the same time; the lining ring is composed of a left half ring and a right half ring which are connected, and an embedded connecting piece is arranged between the left half ring and the right half ring; and lifting rings are arranged at the top of the upper section pile and the top of the lower section pile. Compared with the prior art, in the construction process of a steel pipe pile, water is not needed, so that resources are saved; grouting is not needed in the construction process, so that the influence on the surrounding environment is small; and meanwhile, concrete does not need to be poured in the construction process, the pile forming quality of the concrete does not need to be considered, so that resources are saved, the detection of the formed pile in the later period is reduced, and the construction of the steel pipe pile is facilitated.

Description

Technical field[0001]The invention belongs to the field of pile foundation, in particular, a steel pipe pile foundation and a construction method thereof.Background technique[0002]The pile foundation is a deep basis composition consisting of pile and connecting piles or a single pile foundation connected to the pile foundation. If the pile body is buried in the soil, the bottom surface of the socket is in contact with the soil, For low jacket pile foundation; if the upper portion of the pile is exposed, the bottom is above the ground, referred to as a high bearing pile foundation.[0003]Pile foundation construction technology, there is a wide range of application value in the field of bridge construction and construction, but the traditional borehole incubating pile quality control is difficult, and it is easy to collapse during drilling, and it is difficult to ensure the quality of pile after pouring concrete. . At the same time, the waste mortar produced by the construction has a c...

AI Technical Summary

Problems solved by technology

[0003] Pile foundation construction technology has wide application value in the field of bridge construction and construction research, but the quality control of traditional bored piles is difficult, and it is easy to collapse and shrink the hole during drilling, and it is difficult to ensure the quality of piles after pouring concrete

At the same time, the waste mud produced by the construction has a certain degree of impact on the surrounding environment

[0004] The existing bored piles have the following disadvantages: first, a large amount of mud waste will be generated during the construction process, which is difficult to handle and has very high environmental protection requirements; second, the hole wall is prone to collapse and soil creep during drilling Problems such as collapse and inclination of the borehole; third, the pile body is prone to concrete inclusions, or short piles and broken piles
