Excavation construction method for river-following deep groove close to existing structure
The invention discloses a construction method for excavating a riverside deep groove close to an existing structure, and aims to solve the problems that when the riverside deep groove close to the existing structure is excavated, earthwork at the bottom of a building loses lateral supporting force and cannot bear the pressure of an upper building, so that the building is likely to topple or crack and the like. According to the method, the earth is excavated in a layered mode, the round steel, the formwork and the early-strength impervious concrete are used for retaining earth, the earth collapse at the bottom of the structure is safely and effectively avoided by controlling the layered excavation depth and the arrangement direction and distance of the steel enclosing purlins, the steel plate supports and the like, the cost is reduced, and the safety and quality in the construction period are guaranteed.
本发明公开了一种临近既有构筑物的沿河深沟槽开挖施工方法，本发明旨在解决临近既有构筑物的沿河深沟槽开挖时，建筑物底部的土方失去侧向支撑力，无法承受上部建筑物的压力可能导致建筑物倾倒或开裂等问题。本发明采用分层开挖土方，并用圆钢、模板、早强抗渗混凝土挡土的方式，通过控制分层开挖的深度、钢围檩和钢板支撑等布置的方位和距离，安全有效避免了构筑物底部的土方塌方，降低了成本，保证了施工期间的安全与质量。
