Capping structure above open section of existing tunnel and construction method
The invention discloses a capping structure above an open section of an existing tunnel and a construction method. The capping structure is arranged above the open section of the existing tunnel and comprises side walls arranged on the ground on the two sides of the open section of the existing tunnel and concrete laminated slab beam structures arranged at the upper ends of the side walls on the two sides to bear the upper load of the structure; the concrete composite slab beam structure comprises a plurality of precast beams and concrete cast-in-place slabs laid on the precast beams; the outer sides of the side walls on the two sides and the upper faces of the concrete cast-in-place slabs are filled with needed terrains through filling materials; and during construction, a frame structureformed by simply supporting the precast beams and the side walls is firstly used, then the concrete cast-in-place slabs are poured on the precast beam, finally, the filling material is filled. According to the capping structure, under the condition that traffic in the open section is not affected, the space of the land parcel on the upper portion of the open section can be fully utilized to enable the land parcel to exert larger value, and traveling of surrounding residents is facilitated.
本发明公开了既有隧道敞开段上方加盖结构及施工方法，设置于既有隧道敞开段上方，包括设置于既有隧道敞开段两侧地面的侧墙，以及设置于两侧侧墙上端承担结构上部荷载的混凝土叠合板梁结构；混凝土叠合板梁结构包括若干预制梁，以及铺设于若干预制梁上面的混凝土现浇板；两侧侧墙的外侧，以及混凝土现浇板上面通过填筑材料填充所需要的地形。施工时，先用预制梁与侧墙简支形成的框架结构；然后在预制梁上浇筑混凝土现浇板；最后填充填筑材料。本发明在不影响敞开段内部的交通情况下，能够充分利用敞开段上部地块空间使地块发挥出更大的价值，方便周边居民的出行。
