Problems solved by technology

In addition, the traditional pile foundation composite foundation reinforcement technology only exerts the role of the pile foundation itself, and does little to improve the soil between the piles, and the soil between the piles will also affect the quality of foundation reinforcement

Embodiment Construction

[0010] Such as figure 1 , 2 As shown in 3 and 3, a new construction method of pile-solid-solid-dispersed-material-pile composite foundation with interaction between pile and soil, its construction steps:

[0011] (1) Hole forming. The hole forming process of the grouted pile is basically the same as that of the general bored pile. Generally, a drilling rig is used to form a hole, and the natural pulping wall is used. When the hole wall is not easy to maintain, the artificial pulping wall is used. In engineering applications, bentonite and alkali are used to artificially make slurry to protect the wall, and the specific gravity of the slurry is controlled within a certain range.

[0012] (2) Throw stones to wash the holes. After the drilling is completed, wash the holes twice. The first hole washing is carried out after the drilling is completed and before the aggregate is put in. The second hole washing is carried out during the process of putting in the aggregate, that ...

Abstract

The present invention discloses a new pile-soil interacting slurry fixing dispersed material pile composite foundation construction method. The present invention forms a pile hole from drill getting into foundation to the designed depth. Around the pile hole it adopts slurry to breast wall. Lay slurry fixing pipe in the pile hole, and put aggregate into the pile hole. Infuse serum into the pile hole from grouting pump through slurry fixing. When the serum and aggregate solidify into pile and inleak into the soil body around the pile. Spread underlay layer on top of the pile to form composite foundation. The present invention solves the disadvantages of present technology comprising flexible and rigidit pile composite foundation method, or the pile body intensity is low, or the cost is high. In the present invention, the serum solidifies into pile together with aggregate the pile hole, inleaks into the soil body, and extends to the three parts (the pile body, the serum infiltrating reinforcing body and the natural soil body) of the slurry grouting pile composite foundation, to achieve the composite effect of improving the foundation carrying capability and reducing the settlement. Besides it can protect environment, decrease building costs and break through the ground space limit.

Description

technical field [0001] The invention relates to a construction method of a composite foundation, in particular to a construction method of a novel pile-solid material pile composite foundation in which piles and soil interact. Background technique [0002] Before the present invention, in the engineering constructions such as road, bridge, composite foundation construction method is a kind of method commonly used to deal with soft ground at present, comprises flexible pile composite foundation method (such as crushed stone pile, lime-soil pile and cement mixing pile etc.) And rigid pile composite foundation method (such as CFG pile, PHC pile and PCC pile, etc.). Crushed stone piles are granular piles with low pile body strength, but relatively low cost. CFG piles and PHC piles are rigid piles with high strength and good reinforcement effect, but the cost is high. In actual engineering construction, as a composite foundation technology, pile types with medium bond strength ...
