Tunnel deep foundation pit unblocking temporary steel bridge structure and construction method
The invention relates to a tunnel deep foundation pit unblocking temporary steel bridge structure and a construction method, and the tunnel deep foundation pit unblocking temporary steel bridge structure comprises tunnel bottom plate structure piles which are vertically arranged in a tunnel foundation pit and are distributed below a temporary steel bridge in a matrix shape; the connecting beams are connected with the upper ends of the tunnel bottom plate structure piles in the transverse rows; the supporting beams are connected with the upper ends of the tunnel bottom plate structure piles on the two sides and the middle of the longitudinal row and the foundation pit supporting piles; the steel beams are arranged on the connecting beams and the supporting beams; the bridge deck is arranged on the steel beams; a plurality of bridge deck slabs are spliced to form the bridge deck of the temporary steel bridge; the retaining wall is made of reinforced concrete, arranged on the supporting beam, located on the outer side of the bridge deck slab and abutted against the side edge of the bridge deck slab. The situation that the site of the tunnel foundation pit and the road intersection is small can be effectively met, lateral movement of the bridge deck slab is prevented by arranging the retaining wall, cost can be reduced, the construction procedure can be simplified, and favorable conditions are created for smooth tunnel construction.
本发明涉及一种隧道深基坑保通钢便桥结构及施工方法，包括，隧道底板结构桩，竖向设于隧道基坑内，矩阵状分布于钢便桥的下方；连系梁，与各横排的所述隧道底板结构桩的上端相连；支撑梁，与纵排两侧和中间的所述隧道底板结构桩的上端及基坑支护桩相连；钢梁，为多根，设置于所述连系梁和支撑梁上；桥面板，设置于所述钢梁上；该桥面板为多块，拼接构成所述钢便桥的桥面；挡墙，由钢筋混凝土制成，设置于支撑梁上，位于所述桥面板的外侧，并抵靠在所述桥面板的侧边。本发明可以有效满足隧道基坑与道路交叉口场地较小的情况，并通过设置挡墙，防止桥面板的侧移，还可降低成本，简化施工程序，为隧道施工的顺利进行创造有利条件。
