Occlusal pile technology is also a kind of deep foundation pit supporting technology. In this technology, the cast-in-place pile and the mixing pile are occlusioned. Firstly, a cage type double-layer agitator is used to construct solidified soil piles, and then the undisturbed soil taking and press-pouring concrete pile machine is used to cut adjacent solidified soil piles into holes, and the press-pouring concrete is inserted into the steel cage, which has the dual role of water stop and soil retaining. The technology has the advantages of fast construction speed, low cost and little impact on the surrounding environment.
1Steel sheet pile support technology
Steel sheet piles are synthesized using chains with seals or other flat steel sheets. Since many steel sheet piles are connected to each other to form pile walls, this type of steel sheet wall provides protection and is most frequently used in daily lifeYType,XThe type andSType. The operation process of steel sheet pile support technology will be relatively simple, a relatively wide range of applications, but there are also some disadvantages, because the strength of the steel plate itself is limited, can not pile up too much heavy objects around the steel plate, if too much will lead to steel plate collapse deformation, construction must first consider the influence of the surrounding environment and geographical factors.
2, pile row retaining technology
On the basis of deep foundation pit, one of the commonly used construction techniques is pile row supporting technology, which mainly uses retaining pile and impermeable curtain. In order to improve the effect of soil maintenance, workers generally use reinforced concrete cast-in-place piles. During the design, it is necessary to ensure the scientific position in order to set up a perfect support structure. The technology is relatively simple in construction, no noise, little impact on the surrounding environment, strong toughness. Therefore, it is widely used in deep foundation pit supporting technology.
3, deep mixing pile support technology
This technology mainly uses cement and lime as raw material construction, using mechanical mixing soil and raw material, using special technology to strengthen the loose soil, the formation of cement soil pile, used as foundation pit enclosure. Deep mixing pile technology uses the pile's own gravity to play the role of enclosure, usually combined with anchor rod or internal support used, the technology is low price, simple construction steps, strong applicability.
4And occluding pile technology
Occlusal pile technology is also a kind of deep foundation pit supporting technology. In this technology, the cast-in-place pile and the mixing pile are occlusioned. Firstly, a cage type double-layer agitator is used to construct solidified soil piles, and then the undisturbed soil taking and press-pouring concrete pile machine is used to cut adjacent solidified soil piles into holes, and the press-pouring concrete is inserted into the steel cage, which has the dual role of water stop and soil retaining. The technology has the advantages of fast construction speed, low cost and little impact on the surrounding environment.
