River cofferdam construction method in bridge construction
The invention relates to the technical field of supervision, and discloses a river cofferdam construction method in bridge construction, which comprises the following steps: taking two groups of underground water samples, evaluating the corrosivity of underground water to a concrete structure, considering an environment type II and a strong permeable layer A, and judging that the underground water has weak corrosivity to the concrete structure and has micro corrosivity to steel bars in a reinforced concrete structure; analyzing soluble salt in soil by adopting two groups of soil samples, evaluating the corrosivity of the soil to a concrete structure according to an environment type II and a strong permeable layer A, judging that the soil has micro-corrosivity to the concrete structure, has micro-corrosivity to steel bars in a reinforced concrete structure and has micro-corrosivity to the steel structure, filling the soil into an artificial fill stratum, carrying out river earthwork backfilling, and after backfilling is completed, judging that the soil has micro-corrosivity to the concrete structure, the reinforcing steel bars in the reinforced concrete structure and has micro-corrosivity to the steel structure. And carrying out foundation reinforcement on the groove wall part of the ground wall. According to the river cofferdam construction method in bridge construction, the water quality can be detected before construction, the corrosion performance of the water quality to reinforced concrete is judged, the corrosion performance is detected before construction, and the quality and safety of a project are guaranteed.
本发明涉及监理技术领域，且公开了一种桥梁施工中河道围堰施工方法，采取2组地下水水样，评价地下水对混凝土结构的腐蚀性按Ⅱ环境类型和强透水层A考虑，判断地下水对砼结构具弱腐蚀性，对钢筋混凝土结构中的钢筋具微腐蚀性；采取2组土样进行土中易溶盐分析，评价土对混凝土结构的腐蚀性按Ⅱ环境类型和强透水层A考虑，判断土对砼结构具微腐蚀性，对钢筋混凝土结构中的钢筋具微腐蚀性，对钢结构具微腐蚀性，填入人工填土层，进行河道土方回填工，回填完成后，对地墙槽壁部位进行地基加固。该桥梁施工中河道围堰施工方法，在施工前能对水质进行检测，判断水质对钢筋混凝土的腐蚀性能，在施工前对这进行检测，保证工程的质量和安全。
