Construction method for reinforcing desilting retaining wall of urban landscape riverway
The invention discloses a construction method for reinforcing a desilting retaining wall of an urban landscape riverway. The construction method comprises the following steps that before a river bottom is excavated, firstly a temporary support is arranged on a wall body, a soil body at the toe of the retaining wall is excavated in sections, a concrete continuous wall is poured, transverse U-shaped concrete support beams are arranged in the riverway at intervals, and the riverway is excavated downwards after 80% of the design strength is reached; and then the retaining wall foundation is subjected to grouting reinforcement, and finally the upper temporary support is dismantled. The construction method is feasible in technology, easy and convenient to construct, economical, reasonable and suitable for reinforcing the retaining wall of the urban riverway with the narrow space in the water conservancy project, the problems that the riverway flow capacity is insufficient and retaining walls on the two banks need to be reserved are effectively solved, the riverway can be excavated and deepened, the flood discharge capacity of the riverway is improved, the current retaining wall can be reserved, and buildings on the two banks are not affected.
本发明公开了一种城市景观河道清淤挡土墙加固施工方法，对河底进行开挖前，首先在墙体上设置临时支撑，分段开挖挡墙墙趾处土体，浇筑混凝土连续墙，在河道内间隔设置横向U型混凝土支撑梁，并达到设计强度的80％后再下挖河道。然后对挡土墙地基进行注浆加固，最后拆除上部临时支撑。本方法技术可行、施工简便、经济合理，适用于水利工程中空间狭窄的城市河道挡墙加固，有效地解决了河道过流能力不足、两岸挡土墙需要保留的难题，既能对河道开挖加深，提高河道行洪能力，又能保留现状挡墙，且不影响两岸建筑物。
