Shanghai strong foundation occluding pile technology

The construction technology of cement soil-concrete interlocking pile in Shanghai strong foundation adopts separated cement soil-cement mixing pile to form a row of equally spaced cement soil-cement piles at a time. The original soil-cement mixing pile machine is used to cut part of the cement soil-cement mixing pile between two cement soil-cement mixing piles to form a hole.

Requirements for monitoring deformation of composite support of Shanghai strong section steel

Shanghai STRONG foundation STEEL composite support technology has the advantages of short construction period, low cost, large space and so on. It adopts prestressed fish belly beam structure, also called prestressed fish belly foundation pit steel support. At the same time, the construction quality is strictly controlled, the construction process is standardized, safety and quality first, and the deformation of foundation pit support is strictly monitored. The following is the deformation monitoring of a project:

Section steel combination support - Shanghai strong fish belly beam high strength bolt use precautions

Section steel combination support adopts high strength bolt link. In the construction process, there are the following precautions: 1. High strength bolt can not be used as a temporary bolt for installation. This is easy to cause the hole is not straight, or forced on the hole, so that the connecting plate fits, the screw thread damage of the bolt, the torque coefficient changes, the bolt shaft force is uneven, or the connecting plate produces internal stress.

New technology of foundation pit engineering, effectively shorten 1/4 construction period

This project is a large furniture store invested and built by IKEA in Hefei, Anhui Province, which is a key project of the local province and city in 2020. The project is located at the intersection of Mengcheng North Road and Linquan Road, Luyang District, Hefei City. The surrounding environment is complex, with the subway station of Line 5 in the east, the subway station of Line 3 in the south, and the residential community and municipal pipeline culverts in the west. The proposed building has 4 floors above ground and 1~2 floors underground. The foundation pit depth is 7.2~15.2m and the area is about 19,000 square meters. The original foundation pit supporting scheme is: cast-in-place pile + high pressure rotary jet grouting pile water stop + composite steel support.

Commonly used deep foundation pit supporting 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.
