H-shaped roadbed structure and construction method thereof
The invention provides an H-shaped roadbed structure and a construction method thereof.The H-shaped roadbed structure comprises anchoring piles, longitudinal beams, cross beams, bearing plates and breast boards, the multiple anchoring piles are arranged on the two sides of a roadbed, the anchoring piles on the two sides of the roadbed are symmetrically arranged, and the adjacent anchoring piles in the line direction are connected through the longitudinal beams; anchoring piles symmetrically arranged in the cross section direction of the roadbed are connected through cross beams, a bearing plate is arranged between every two adjacent cross beams in the line direction, the bearing plates are provided with drainage slopes from the center of the roadbed to the outside, and medium-coarse sand sandwiched composite geomembranes are laid on the drainage slopes. And soil retaining plates are arranged between the pile tops of every two adjacent anchoring piles and the longitudinal beams and behind the ear walls of the anchoring piles in the line direction. The cross beam serves as a supporting structure of the bearing plate and forms an integral structure with the anchoring piles on the two sides, soil pressure borne by the anchoring piles on the two sides becomes a pair of acting force and counter-acting force through the cross beam, unfavorable external loads are converted into favorable external loads, displacement of anchoring points is effectively restrained, the structure is more reasonable, the safety risk is low, and the manufacturing cost is low.
本发明提供一种H型路基结构及其施工方法，H型路基结构包括锚固桩、纵梁、横梁、承载板和挡土板，在路基的两侧设有若干根锚固桩，路基两侧的锚固桩对称设置，沿线路方向相邻锚固桩通过纵梁相连，沿路基横断面方向对称设置的锚固桩通过横梁相连，沿线路方向每相邻两道横梁之间设有承载板，承载板设置由路基中心向外的排水坡，其上铺设中粗砂夹复合土工膜，沿线路方向每相邻两根锚固桩在桩顶至纵梁之间、锚固桩耳墙背后设置挡土板。横梁不仅作为承载板的支撑结构，同时与两侧锚固桩形成整体结构，利用横梁使两侧锚固桩所受土压力成为一对作用力与反作用力，将不利外荷转换有有利外荷，有效约束锚固点位移，结构更为合理，安全风险低，造价经济。
