RCP reinforced composite foundation treatment technology

RCP strong pile is a combination of sand and stone pile, cement and soil rotary shotcrete mixing pile and rigid pile (precast concrete pile, cast-in-place pile and steel pile) bearing and construction technology advantages, according to the soil conditions, soft foundation treatment requirements, adopt a variety of combination methods By optimizing the pile diameter, pile length, ash content, aggregate grading and other parameters, it can give full play to the friction resistance and end resistance of the soil around the pile and match the strength of the pile material to produce a high enough single pile bearing capacity, and can significantly improve the strength of soil between piles.

Steps for stability assurance of steel support in foundation pit support

The foundation pit excavation should strictly abide by the principle of "layered excavation". The steel support of foundation pit should be set up in close coordination with the earth excavation, and the central excavation method should be adopted to excavate the earth near the steel support in order to prevent mechanical collision and support. The earthwork near the slope protection pile shall be excavated with manual assistance of small machines and tools. Mechanical excavation of collision steel support and bored cast-in-place piles shall be strictly prohibited. After the earthwork is excavated to the designed elevation, steel support shall be erected in time and prestressed shall be applied to reduce the exposure time without support.

Precautions for high strength bolt connection of steel support in foundation pit support

High strength bolts should not be used as temporary bolts for installation of steel bracing in foundation pit. 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. The friction surface should not be treated carelessly or the high-strength bolts should be installed without treatment. In this way, there will be a sandwich between the friction surface and the friction surface will not be properly protected.

Supply and acceptance inspection of steel support members for foundation pit support

The hoisting of steel supporting components for foundation pit supporting is carried out according to the pre-made installation flow sequence. The numbered components transported to the designated location on the site shall enter the site at least one day in advance to meet the requirements of the hoisting schedule. The entering components shall be reasonably distributed according to the design scheme and the hoisting area.

Construction process of large diameter rotary jet grouting pile

Large diameter rotary jet piles are constructed by drilling a guide hole with a 150 mm diameter drill bit with a jet monitor that turns on a high pressure jet when the designed toe level is reached. The spray treatment is initiated by breaking up the soil particles using high-pressure grouting, which is then sprayed and mixed for stirring under the rotation and upward motion of the nozzle.

Construction principle of large diameter rotary jet grouting pile

The construction of large diameter rotary jet grouting pile is proposed to adopt double pipe jet grouting, which is composed of air and slurry in the grouting process. The enveloped air is used to enhance the progressive cavity widening in the soil, allowing the jet to penetrate further, forming a larger diameter than the single-tube system. In addition, it blows out the cutting mud to prevent the drilling annulus from plugging and thus preventing the ground uplift.
