Problems solved by technology

At the same time, the construction equipment is special equipment, and the construction team is small, etc.
Pipe pile composite foundation is widely used in industrial and civil construction foundations. Pipe pile composite foundation has the advantages of easy guarantee of pile quality, large construction depth, strong anti-extrusion ability of pile body, and fast construction speed; The pile bearing capacity is small, the replacement rate of the composite foundation is small, the pile-soil coordination and deformation ability is poor, and the cost per unit area is high, etc.

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings, but it does not constitute any limitation to the present invention.

[0020] Such as figure 1 As shown, the method for reinforcing soft ground with large-diameter thin-walled pipe pile composite foundation of the present invention, its technological process is: large-diameter thin-walled pipe pile prefabrication → pipe pile construction → cushion layer is set, and now each process is described as follows:

[0021] Prefabrication of large-diameter thin-walled pipe piles: First, large-diameter thin-walled pipe piles are prefabricated in the factory. Compared with ordinary pipe piles, this kind of large-diameter thin-walled pipe piles has the characteristics of lower concrete strength, smaller wall thickness / diameter, and less reinforcement; The diameter of the pipe pile is usually 600-1000mm, and the wall thickness is 50-100mm.

[0022] Pipe pile construction: use constru...

Abstract

The method includes following steps: (1) prefabricating big and thin wall pipe piles; (2) according to designed reinforcing requirement, punching or pressing the said prefabricated pipe piles into base of foundation in soft clay by using construction machinery; (3) setting mattress layer on top of pipe piles to assort with distortion and stress of pile ground. Advantages are convenient construction, low cost, fast, adjusting distortion of pile ground so as to ensure piling quality and suit reinforcing base of foundation in soft clay.

Description

technical field [0001] The invention relates to a soft foundation reinforcement technology, in particular to a method for reinforcing a soft foundation with a large-diameter thin-wall pipe pile composite foundation. Background technique [0002] At present, barrel pile foundation, pipe pile composite foundation, concrete composite foundation and so on are widely used in highway soft clay foundation treatment. The barrel pile foundation has the advantages of large pile diameter, double-sided friction, large replacement rate, and low cost per unit area. However, because the barrel pile adopts the construction technology of immersed tube pouring concrete, the construction depth is limited by the construction machinery, and the concrete needs to be maintained. , The construction speed is slow, the construction period is long, the concrete strength of the pile body is low, the quality of the concrete is difficult to guarantee, the anti-extrusion ability of the pile body is weak, ...
