Vertical prestressed steel pipe pile structure and construction method thereof
The invention provides a vertical prestressed steel pipe pile structure and a construction method thereof.The vertical prestressed steel pipe pile structure comprises a steel pipe arranged on a steel pipe pile, and the lower end of the steel pipe is of an embedded structure and used for increasing the lateral friction resistance of the steel pipe pile; the embedded structure further comprises an expanding weighing body arranged on the vertical pre-stressed anchor rod in a penetrating mode, and the expanding weighing body exerts lateral extrusion force to embed the embedded structure into the soil body. The steel pipe piles are combined with the prestress vertical prestress anchor rods, the steel pipe piles bear shear force, grouting is conducted through expansion bodies on the lower portions of the steel pipe piles, the anchoring force of the anchor cables is increased, and therefore the anti-pulling and anti-sliding capacity of pile bodies is improved, the method is an effective treatment method for micro-miniature engineering projects in recent years, construction machinery is small, the occupied area is small, and construction cost is low. And the construction cost can be greatly saved.
本发明提供了一种竖向预应力钢管桩结构及其施工方法，包括设置于钢管桩上的钢管，所述钢管下端设置为嵌入式结构，用于增加钢管桩的侧向摩阻力；还包括贯穿设置于竖向预应力锚杆上的扩称体，所述扩称体施加侧向挤压力将嵌入式结构嵌入土体内；采用钢管桩结合预应力竖向预应力锚杆，既钢管桩承受剪切力，也通过钢管桩下部扩大体注浆，增加锚索锚固力，从而提高桩身得抗拔、抗滑能力，是近年来在微小型工程项目的有效处理方法，并且施工机械小，占地范围小，从工程造价上也能得到很大的节约。
