Problems solved by technology

In two-way extrusion, as the angle increases, the upper and lower arms of the soil near the pile are separated from the soil, and the effect of squeezing the soil is relatively poor
[0013] Therefore, the degree of extrusion of the soil by the current extrusion and expansion equipment is not ideal, which affects the bearing capacity of the load-bearing disc piles, and easily causes the soil to collapse and produce sediment

Abstract

The invention relates extruding-expanding device and method for a pile foundation. The device comprises a supporting device and an extruding-expanding arm connected with the supporting device, wherein the extruding-expanding arm comprises a telescopic expanding arm. The extruding-expanding device and method for the pile foundation overcome the defects of a single-cylinder one-way extruding-expanding device and a double-cylinder two-way extruding-expanding device and prevent the soil mass from falling in an arm with a box-shaped section; the telescopic extruding-expanding arm always contacts the soil mass, and the soil mass is fully compacted; the horizontally-projected area of an extruded disk cavity is larger; and the bearing capacity of an extruding-expanding pile is larger.

Description

technical field [0001] The invention relates to an extrusion device and an extrusion method for pile foundations, in particular to a hydraulic telescopic extrusion device and method. Background technique [0002] At present, in the construction of foundation engineering, piles with load-bearing plates and load-bearing forks are usually formed by extrusion equipment; composition. Its machine head is composed of hydraulic cylinder device, extrusion arm, pressure sensor and so on. The extruding arm is composed of an upper extruding arm and a lower extruding arm. The upper extruded expansion arm and the lower extruded expanded arm are generally rigid components, which are non-stretchable structures. One of the single-cylinder one-way extrusion and expansion equipment, see figure 1 , the upper arm AB, and the lower arm BC, A\B\C motion trajectory is as follows: [0003] Point A, x=0, y=↓; [0004] Point B, x=←, y=↓; [0005] Point C, x=0, y=0; [0006] As shown in the acc...
