Concrete prefabricated pipe piles that only bear the pull-out effect

Abstract

The invention belongs to the field of construction engineering, and in particular relates to a concrete prefabricated pipe pile which only bears the anti-pulling effect. Concrete prefabricated tubular piles that only withstand uplift, including: concrete prefabricated pile body, detachable hollow guide rod, metal pile tip, concrete prefabricated pile body with pile top and pile bottom, concrete prefabricated pile body driven into the foundation soil; concrete The cavity of the prefabricated pile body is provided with a detachable hollow guide rod, the bottom end of the detachable hollow guide rod is provided with a pile tip connecting thread, and the top end of the metal pile tip is provided with a guide rod connecting thread, and the detachable hollow guide rod is connected with the metal pile tip thread. connect. The invention has the following beneficial effects: as for the metal pile tip, as for the concrete prefabricated pipe pile tip, the pile tip can penetrate the hard soil layer more easily, improve the pile driving efficiency, and reduce the disturbance to the surrounding soil body; Recycling and reuse can form a cavity between the pile tip and the foundation soil to save materials. The size of the metal pile tip can be customized and used in a wide range.

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
