Construction method for constructing gateway in limited space of underneath pass bridge
The invention provides a construction method for constructing a gateway in a limited space of an underpass bridge. The construction method comprises the following steps: S1, setting a proper construction position; s2, marking a routing path, a construction starting point and a construction ending point of the gateway; s3, construction of a first cast-in-place pile is conducted; s4, the first cast-in-place piles on the two sides are connected and fixed through a positioning frame; s5, the first digging pits and the second digging pits are dug, and meanwhile the second digging pits are formed in the two sides of the direction of the gateway; s6, construction of a third digging pit is conducted at the same time, and the first digging pit, the second digging pit and the third digging pit are arranged in a stepped mode; s7, excavation is continued; s8, circulating the steps S3-S6 until a second foundation pit body is formed; s9, construction of a third cast-in-place pile is completed; s10, forming a first communicating foundation pit; s11, the steps S3-S10 are repeated until the second communication foundation pit and the continuous row cast-in-place piles are completed; and S12, formwork erecting, pouring and filling are conducted, and a design target pit is formed. Construction is efficient, the overall construction efficiency can be greatly improved, and operation safety is guaranteed.
本发明提供一种下穿桥梁的有限空间内施工闸道的施工方法，包括以下步骤：S1、设置合适的施工位置；S2、标记出闸道的走线路径、施工起点和终点；S3、进行第一灌注桩的施工；S4、两侧的第一灌注桩通过定位架连接固定；S5、开挖第一开挖坑和第二开挖坑，同时在沿闸道的走向两侧设置第二开挖坑；S6、同时进行第三开挖坑的施工，第一开挖坑、第二开挖坑和第三开挖坑成阶梯设置；S7、继续开挖；S8、循环S3~S6，直至形成第二基坑体；S9、完成第三灌注桩的施工；S10、形成第一连通基坑；S11、重复S3~S10，直至完成第二连通基坑和连排灌注桩；S12、立模浇筑填充，形成设计目标坑。本发明施工高效，能大幅度提高整体的施工效率，保证作业安全。
