Embodiment Construction

[0031] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] In this embodiment, the construction method of the underground pipe gallery in Wuzhong City is taken as an example for illustration.

[0033] G

[0034] There are three underground pipe galleries in the eastern part of Wuzhong City that need to cross the Qingshui River. The Qingshui River is 15m wide and 1.5-2.5m deep in the dry season, and 25m wide and 4.5m deep in the flood season and spring irrigation season. The section of the pipe gallery crossing the river plan and section see pictures respectively figure 2 and image 3 .

[0035] Construction Design and Construction Technology

[0036] In order to ensure the safety of the bridge crossing the river section and the normal flow of the river in the future, after communicating with the design, the section 1 of the pipe gallery crossing the river is moved 15m northward, and sinks ...

Abstract

The invention provides a construction method for an underground pipe gallery crossing a river, comprising the following steps: setting out the line to determine the position of the excavation line of the pipe gallery crossing the river section; excavating and connecting the upstream and downstream of the excavation line of the pipe gallery crossing the river section at a safe distance The diversion open channel; the first cofferdam and the second cofferdam that can intercept the water flow are respectively set on both sides of the excavation line of the pipe gallery crossing the river; after the area between the first cofferdam and the second cofferdam is dewatered Excavate from one end of the excavation line of the pipe gallery crossing the river section, excavate to the designed depth, set the first foundation pit support on the side wall of the foundation pit, continue excavating to the final depth required by the pipe gallery crossing the river section, and Set the second foundation pit support on the side wall of the foundation pit below the first foundation pit support; construct the pipe gallery crossing the river section in the normal order, and carry out waterproof treatment on the section of the pipe gallery crossing the river after construction; backfill the foundation pit After the completion, the river will be changed back to the old course, and the construction of the pipe gallery will continue. The invention has the advantages of simple process, excavable technical method, guaranteed safety, low cost and reasonable economy.

Description

technical field [0001] The invention relates to the technical field of municipal construction, and more specifically, relates to a construction method for an underground pipe gallery crossing a river. Background technique [0002] The urban underground comprehensive pipeline gallery is a construction project that has gradually emerged in recent years by learning from foreign advanced urban underground pipeline management experience. Through the construction of underground comprehensive pipe gallery, all directly buried water (water supply, reclaimed water, sewage), electricity (electricity, telecommunications), heating (heating), gas, etc. are all introduced into the pipe gallery, and monitoring and other facilities are added to the pipe gallery. Ensure convenient maintenance in the later period. Newly added pipelines, there are many water systems in the city for landscape or for urban water supply, flood drainage, irrigation, and even many cities live by water and build by...
