Prefabricated mushroom-shaped pile cap for pile-supported reinforced embankment
The invention discloses a prefabricated mushroom-shaped pile cap for a pile-supported reinforced embankment. The prefabricated mushroom-shaped pile cap is characterized in that a prefabricated pile cap comprises a base platform, wherein the upper surface of the base platform protrudes upwards to form a cambered surface, and the cambered surface uniformly and excessively extends to the edge of theupper surface of the base platform from the top of the upper surface of the base platform; a reserved pile hole is formed in the lower surface of the base platform, and the top end of a rigid pile isembedded into the reserved pile hole to be detachably connected with the prefabricated pile cap; and the upper surface of the base platform is tightly attached to a geotechnical reinforcing rib. The pile cap structure can form an arc-shaped structure at the top end of the rigid pile of the pile-supported reinforced embankment, promotes the deformation of the geotechnical reinforcing rib, can promote the exertion of the soil arching effect and the reinforcement effect, and can prevent the geotechnical reinforcement from being damaged at the edge of the pile cap due to overlarge local strain.
本发明是一种桩承式加筋路堤的装配式蘑菇状桩帽，预制桩帽包括基台，所述的基台的上表面向上突起形成弧面，所述的弧面由基台上表面的顶部均匀过度延伸至基台上表面的边缘；所述的基台的下表面设置有预留桩孔，刚性桩的顶端嵌入预留桩孔内与预制桩帽可拆卸连接；所述的基台的上表面与土工加筋紧密贴合。该种桩帽结构能够在桩承式加筋路堤的刚性桩顶端形成弧形结构，促使土工加筋形变，能够促进土拱效应和加筋效应发挥，并可避免土工加筋在桩帽边缘因局部应变过大而破坏。
