Construction method and structure for open cut underground pipe gallery inverted siphon undercrossing river
The invention discloses a construction method and structure for an open-cut underground pipe gallery to pass through a river in an inverted siphon mode, relates to the technical field of comprehensive pipe galleries, and solves the problems of structural leakage and structural floating of a pipe gallery structure in the prior art, and the specific scheme is as follows: the construction method for the open-cut underground pipe gallery to pass through the river in the inverted siphon mode comprises the following steps: excavating a standard section foundation pit; paving a waterproof coiled material on a base, and backfilling a foundation pit after the main body structure is constructed; river guide and modification are conducted on the inverted siphon section, concrete cast-in-place piles are constructed after guide and modification, then excavation of a foundation pit of the inverted siphon section and arrangement of concrete inner supports are conducted at the same time, waterproof coiled materials are laid after an anti-seepage plate is arranged on a base, a main body structure is constructed, a layer of waterproof coiled materials is laid on the outer side of the main body structure, a clay anti-seepage layer is backfilled firstly, and then a mixed gravel transition layer is backfilled; and a waterproof system of the impervious plate, the outer waterproof roll and the thick clay layer is formed, then foundation pit backfilling is conducted, and foundation pit cast-in-situ bored piles and concrete inner supports are used as ballasting plates.
本发明公开了一种明挖地下管廊倒虹吸下穿河流的施工方法及结构，涉及综合管廊技术领域，解决了现有技术中管廊结构存在结构渗漏和结构上浮的问题，具体方案如下：一种明挖地下管廊倒虹吸下穿河流的施工方法，标准段基坑开挖，基底铺设防水卷材，主体结构施工后进行基坑回填；倒虹吸段进行河流导改，导改后再施工混凝土灌注桩，之后倒虹吸段基坑开挖与布置混凝土内支撑同时进行，基底设置抗渗板后铺设防水卷材，再施工主体结构，主体结构外侧铺设一层防水卷材并先回填黏土防渗层后回填集配碎石过渡层，形成抗渗板+外防水卷材+厚黏土层的防水体系，之后进行基坑回填，利用基坑钻孔灌注桩及混凝土内支撑施作压重板。
