Construction method for underground comprehensive pipe gallery passing through river channel under bridge
The invention discloses a construction method of an underground comprehensive pipe gallery penetrating through a river channel under a bridge, and particularly relates to the technical field of pipe gallery construction, the specific construction method comprises the following steps: S1, preparation before construction; s2, an outer protective fence is installed; s3, pipe gallery construction; s4, earth excavation and soft foundation treatment; s5, supporting facility arrangement; s6, pipeline installation; s7, pipeline connection; s8, pipeline testing; s9, foundation pit backfilling is conducted, specifically, after pipeline installation and testing are completed, backfilling is conducted, and the ground is restored; and S10, quality inspection. The design has the advantages that space is saved, construction efficiency is improved, the environment is protected, pipeline durability is improved, and maintenance and management are convenient, the effects of reducing noise and reducing flying dust in a construction area can be achieved, the safety and stability of the foundation at the bottom of the pipe gallery are improved, scouring to the side wall of the cofferdam caused by fast water flow can be effectively resisted, and the service life of the cofferdam is prolonged. The stability of the cofferdam is improved, and the construction safety and the construction reliability are improved.
本发明公开了一种桥下下穿河道地下综合管廊施工方法，具体涉及管廊施工技术领域，具体施工方法步骤如下：S1、施工前准备；S2、安装外防护围挡；S3、管廊施工；S4、土方开挖和软基处理；S5、支撑设施设置；S6、管道安装；S7、管道连接；S8、管道测试；S9、基坑回填：在管道安装和测试完成后，进行回填，恢复地面；S10、质量检查。本发明设计具有节省空间、提高施工效率、保护环境、提高管线耐久性、便于维护和管理的优点，并能够起到对施工区域降低噪音和减少扬尘的效果，管廊底部基础的安全性和稳定性提高，且可以有效抵御水流较快对围堰侧壁造成的冲刷，提升围堰的稳固性，提高施工的安全性和施工可靠性。
