Lift-off pile foundation structure for soft soil foundation

Abstract

The invention discloses a lift-off pile foundation structure for a soft soil foundation, and belongs to the technical field of pile foundations. The lift-off pile foundation structure comprises a shell, wherein a reinforcing mechanism is arranged in the shell; and the outer side of the shell is provided with an outer cover ion a sleeved mode, the upper surface of the outer cover is fixedly connected with a positioning mechanism, and the positioning mechanism is detachably connected to the outer side of the shell. According to the lift-off pile foundation structure for the soft soil foundation,by arranging the reinforcing mechanism, when a supporting column is hammered, the supporting column moves downwards and drives a triangular block to move downwards, at the moment, the triangular block extrudes a sliding block, the sliding block is extruded to drive one ends of first inserting rods to move, the first inserting rods move in first sliding sleeves, at the moment, the first insertingrods can be inserted into soil, meanwhile, when a hemisphere block at the upper portion moves downwards, two hemisphere blocks get close to each other, at the moment, the hemisphere blocks can extrudesteel balls, the steel balls can move after being extruded, at the moment, the steel balls can drive second inserting rods to move, and meanwhile, the plurality of second inserting rods can be inserted into the soil, so that the shell is reinforced, and then a pile foundation is stabler during fixing.

Description

technical field [0001] The invention belongs to the technical field of pile foundations, in particular to a lift-off type pile foundation structure for soft ground. Background technique [0002] A deep foundation consisting of a pile and a pile cap connected to the top of the pile (referred to as a cap) or a single pile foundation connected by a column and a pile foundation, referred to as a pile foundation. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Construction pile foundations are usually low cap pile foundations. Pile foundations are widely used in high-rise buildings. [0003] There are some deficiencies in the existing pile foundation structure function. If it is used in the case of soft soil foundation, its fixing effect...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the existing deficiencies in the existing pile foundation structure function, if it is used in the case of soft soil foundation, its own fixing effect is relatively poor, and the pile foundation is prone to inclination or deviation. At this time, it is easy to affect the construction project, and the cushioning and lifting effect of the existing lift-off pile foundation is poor. When encountering strong vibration, the bottom is easily affected by the vibration. Unable to buffer the external pressure, the pile foundation is easily damaged and affects the construction, and the proposed pile foundation structure based on lift-off type for soft soil foundation
