Construction method of six - axis mixing pile for Shanghai strong foundation

Six-axis mixing pile is a new type of soil-cement pile developed in Shanghai strong foundation. It inherits the principle of biaxial mixing pile and the advantages of less displacement soil, small water-cement ratio and low cost. It overcomes the defects of biaxial and three-axis mixing pile, such as low efficiency, low automation degree of pile foundation, high labor intensity of workers and poor mechanical safety performance. Construction method:

Preparation work before construction of six-axis mixing pile for Shanghai strong foundation

Six axial mixing pile is a strong foundation in the existing Shanghai uniaxial and biaxial, three-axis mixing pile on the basis of the development of a new type of cement-soil pile, inherited the principles of the biaxial mixing pile and displacement of soil, water cement ratio is small, low cost, less advantages, overcomes the biaxial and triaxial mixing pile work efficiency is low, the low degree of automation, the labor intensity of workers, poor mechanical safety defects.

Shanghai strong foundation pit steel support technology

Compared with the traditional concrete inner bracing and steel bracing, the steel bracing of Shanghai STRONG foundation pit greatly improves the overall steel degree and stability of the supporting system. Combined with the remote real-time monitoring system, the foundation pit displacement can be effectively and precisely controlled, and the deformation of the foundation pit can be greatly reduced. The following is the construction process scheme of steel support for foundation pit of a project:

Construction technology of pressure grouting pile

Shanghai has a strong foundation undisturbed soil pressure pouring concrete pile technology, pressure filling pile technology has the following advantages: (1) the good quality of pile concrete from the tool center to the hole medium pressure, less material is close-grained, broken pile and necking phenomenon, the soil around the pile hole by compaction, not easy to happen the surface uplift, slumping hole and reducing adverse phenomenon, overall, good pore forming quality.

Installation and emplacement of pile machine before the construction of press-poured pile

Before the construction of pressurized poured pile, the situation of pile foundation operation area should be determined to ensure the stable construction of pressurized poured pile. The following contents are the installation preparations of pile machine before the construction of pressurized poured pile in Shanghai strong foundation: (1) The foundation of the operation area should be treated before the pile machine is in place. The bearing capacity of the treated foundation is required to reach 160KN/m2. If not, the subgrade box should be used for reinforcement to ensure that the foundation does not suffer from uneven settlement.

Construction technology of pressure grouting pile

1. Strong adaptability: The pile type is suitable for clay soil, silt soil, filled soil and other soil types, and can be used for pile formation under complex geological conditions such as reduced diameter soft soil, flowing sand layer, sand pebble layer and groundwater. 2, pile quality is good: due to the concrete from the center of the drill pipe into the hole, the concrete has the characteristics of dense, constant pile, no shrinkage neck, and can penetrate, compaction pile hole around the soil.
