Concrete prefabricated pipe pile only bearing anti-drawing effect

Abstract

The invention belongs to the field of constructional engineering, and particularly relates to a concrete prefabricated pipe pile only bearing an anti-drawing effect. The concrete prefabricated pipe pile only bearing the anti-drawing effect comprises a concrete prefabricated pile body, a detachable hollow guide rod and a metal pile tip. The concrete prefabricated pile body is provided with a pile top and a pile bottom. The concrete prefabricated pile body is driven into foundation soil. The detachable hollow guide rod is arranged in a cavity of the concrete prefabricated pile body, a pile tip connecting thread is arranged at the bottom end of the detachable hollow guide rod, a guide rod connecting thread is arranged at the top end of the metal pile tip, and the detachable hollow guide rod is in threaded connection with the metal pile tip. The concrete prefabricated pipe pile has the following beneficial effects that the metal pile tip is arranged on a pile tip of the concrete prefabricated pipe pile, pile sinking pierces into soil mass to more easily penetrate through a hard soil layer, the efficiency of pile sinking is improved, and disturbance for the surrounding soil mass is reduced; and the pile tip can be recycled, a cavity can be formed between the pile tip and the foundation soil, the purpose of saving materials is achieved, the size of the metal pile tip can be customized, and the use range is wide.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a concrete prefabricated pipe pile which only bears the uplift resistance. Background technique [0002] With the development of social economy, people's requirements for residential buildings are getting higher and higher. At present, basements have become a common configuration of residential buildings. For villa projects with a low number of storeys, the pressure on the base is not large, and it can be transferred to the foundation through the form of natural foundation. The scheme cannot meet the requirements of use, and it is necessary to use pile foundation instead. In the design of conventional pile foundations, both pressure bearing and anti-floating are satisfied by the pile foundation. In the pressure-bearing design, the upper load is concentrated on the pile foundation, and the upper load carried by the single pile is relatively large. In order to ...

Problems solved by technology

[0003] For such projects that mainly bear pressure and have anti-floating conditions, it is feasible to use conventional pile foundation design, but the economy is not good

However, only using natural foundation, although it can meet the conditions of pressure bearing, and the economy is better, but it is helpless for the conditions of anti-floating
