Composite piles and retaining wall formed by cementing solidified soil group piles and precast piles
The invention discloses composite piles and a retaining wall formed by cementing solidified soil group piles and precast piles. Each solidified soil group pile is formed by arranging a plurality of solidified soil pile bodies in a lap joint mode. The number of the solidified soil pile bodies arranged in the direction where the horizontal stress of a pile foundation is large is greater than the number of the solidified soil pile bodies in other directions. Each solidified soil pile body is a mixing pile or a jet grouting pile. The unconfined compressive strength of solidified soil is greater than 0.5 MPa. Each precast pile is a prestressed reinforced concrete pile or a steel pipe concrete pile; and the precast piles are inserted before the initial setting of the solidified soil pile bodies, and the precast piles and the solidified soil pile bodies are cemented together after the hardening of the solidified soil. The composite piles formed by cementing the solidified soil group piles and the precast piles have high horizontal bearing capacity, and the control capacity of the retaining wall on horizontal deformation is improved. The composite piles and the retaining wall formed by the cementing solidified soil group piles and the precast piles has green, environment-friendly, safe and reliable social benefits, meanwhile, the manufacturing cost can be reduced, the construction period can be shortened, and the economic value is high.
本发明公开了由固化土群桩与预制桩胶结的复合桩和挡土墙，其中的固化土群桩是由多根固化土桩体相互搭接排列而成；沿桩基水平受力大的方向上排列的固化土桩体数量多于其它方向上的；固化土桩体是搅拌桩或旋喷桩；固化土的无侧限抗压强度大于0.5MPa；预制桩是预应力钢筋混凝土桩或钢管混凝土桩；预制桩在固化土桩体初凝前插入，固化土硬化后二者胶结在一起。由固化土群桩与预制桩胶结的复合桩将具有较高的水平承载力，其挡土墙对水平变形的控制能力达到提高。该专利具有绿色、环保和安全可靠的社会效益，同时能降低造价和缩短工期，具有较大的经济价值。
