Enclosure river excavation construction method capable of reducing influence of bridge
The invention relates to the technical field of riverway excavation engineering, discloses an enclosure riverway excavation construction method capable of reducing the influence of a bridge, and solves the technical problem of how to reduce the influence on the safety of an original bridge pile foundation during riverway excavation in the prior art. Judging that the steel structure has micro corrosion; s2, enclosure construction distribution, wherein an early-stage construction team is responsible for river enclosure, enclosure shielding and on-site temporary facilities; s3, a river channel is excavated; s4, stress detection; a stress value in a soil body area is detected before excavation, a stress value in the soil body area is detected after excavation, the stress value in the soil body area is detected, the stress value in the soil body area is divided by the stress value in the former, a proportion value is calculated and compared with a set safety threshold value, and if the value is lower than an installation threshold value, a backfilling mode needs to be adopted to guarantee certain stress requirements; and S5, carrying out overall project quality acceptance. According to the technical scheme, the invention provides the excavation construction method for the enclosure river channel capable of reducing the influence of the bridge.
本发明涉及河道开挖工程技术领域，其公开了一种降低桥梁影响的围护河道开挖施工方法，解决了现有技术中的如何在开挖河道时降低对原桥梁桩基的安全性影响的技术问题，包括以下步骤：S1：地下水腐蚀性评价，判断对于对钢结构具微腐蚀性；S2：围护施工分配，前期施工队负责河道围护、围蔽和现场临时设施；S3：河道开挖；S4：应力检测；在开挖前检测土体区域内的应力数值，在开挖后检测土体区域内的应力数值，将后者除以前者，计算占比数值，并于设定的安全阈值相比，如果低于安装阈值，则应采用回填方式保障一定的应力需要；S5：整体工程质量验收。根据以上技术方案，本发明提供一种降低桥梁影响的围护河道开挖施工方法。
