Problems solved by technology

[0002] At present, the construction of pile foundations with diameters above medium in my country has been developed into holes formed by rotary drilling rigs, and the work efficiency has been greatly improved. However, there is no major improvement in China for small and medium-diameter piles. Traditional submersible drilling rigs are relatively fast in forming holes, but their adaptability to strata is limited. There is also the problem of the catheter perfusion process

Abstract

The invention discloses a method for cast-in-place pile bar inserting after concrete pressure irrigation of a long auger drilling hole. The method includes the following steps that (1) a long spiral drilling machine drills a hole until the designed depth is obtained; (2) pressure irrigation of concrete into the hole with a certain pressure is carried out by using a high-pressure concrete pump through a drill stem center channel while a long spiral drill is lifted, and concrete irrigation is carried out until the set elevation is obtained; and (3) in virtue of the dead load of steel cage and / orspecial vibration equipment, a steel cage is inserted into the concrete to reach the designed elevation to form a reinforced concrete cast-in-place pile. The method has the beneficial effects that the quality of a pile body is easy to ensure, the concrete compactness is good, strength is high, soil is in close contact with a surrounding soil body, and the friction force of the pile body is increased; and the pile tip has no virtual soil, pile breaking, diameter reducing, hole collapse and other common quality problems are prevented.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a method for pouring cast-in-place piles with long auger holes for pressing and pouring concrete Background technique [0002] At present, the construction of pile foundations with diameters above medium in my country has been developed into holes formed by rotary drilling rigs, and the work efficiency has been greatly improved. However, there is no major improvement in China for small and medium-diameter piles. Traditional submersible drilling rigs are relatively fast in forming holes, but their adaptability to strata is limited. There is also the problem of the catheter perfusion process. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for the construction of small and medium-sized pile foundations, which solves the two major technical problems of pressure grouting and bar insertion during co...
