Description
Technical field
The present invention relates to the pile foundation of building structure or the removing of foundation pile, especially relate to the sawed-off method and the device thereof of foundation pile.
Background technology
Foundation pile is the basis of building, and building is high more usually, and its foundation pile is dark more.Along with the development of society, traffic is more and more flourishing, and subway is all being built in many cities as the instrument of Modern Traffic.Yet, in the building course of subway, need to remove many buildings, remove in the process of building, just comprise the dismounting of its foundation pile.
Foundation pile has two kinds, and 1) the steel concrete foundation pile; 2) steel pipe pile.In the prior art, the pile foundation method for dismounting has three kinds: 1) driving, and promptly use jump bit to impact broken stub, grab out the broken residual body of useless stake with grab bucket then; 2) pulling out method adopts the large-tonnage crane gear directly to extract pile body; 3) off-centre twists off method.Noise was bigger when the shortcoming that driving exists was to construct, and can't guarantee the degree that the pile foundation body is broken, was applicable to and buried more shallow pile foundation, and for the pile foundation that all-metal constitutes, punch method is also inapplicable.The problem of dial-out method is crane gear is required height, and required expense is big, has the big problem of noise equally, and dark stub is inapplicable for burying.It is brute force to be carried out in the stake of giving up step by step twist off that off-centre twists off method, up to certain degree of depth.For burying very dark useless stake, it is huge thoroughly to remove cost.In the engineering practice, often need remove the above stub of certain depth, the requirement of iron formation gets final product contentedly.
Summary of the invention
