Urban channel dike retaining wall structure and construction method
The invention discloses an urban channel embankment retaining wall structure and a construction method. The retaining wall structure comprises an embankment, a water retaining system and a drainage system. The dike comprises a gravity type retaining wall and a concrete bottom plate, the gravity type retaining wall is of a right trapezoid section, the upstream side is vertical, the top of the concrete bottom plate is a horizontal plane and bears the gravity type retaining wall, the upstream side is thickened, and the dike is arranged on the two sides of the channel; the water retaining system comprises at least two groups of breast boards which can be moved into or out of the channel to connect and disconnect water flow, and an enclosure space formed by the two groups of breast boards and the dike is used as a construction area; the drainage system comprises a drainage main pipe and a drainage branch pipe, the drainage main pipe is arranged along the backwater side slope toe of the gravity type retaining wall in a full-length mode and located at the top of the concrete bottom plate, and the drainage branch pipe is located at the top of the concrete bottom plate and communicated with the channel at one end and connected into the drainage main pipe at the other end. The front portion of each drainage branch pipe is provided with a gate groove and a gate capable of sliding up and down along the gate groove, the drainage system is opened and closed by opening and closing the gates, and the drainage branch pipes are arranged on the outer sides of the at least two breast boards to serve as water inlet ends and water outlet ends respectively. The fabricated water retaining system and the pre-embedded drainage system are adopted, and rapid assembly and construction can be achieved; through gate lifting and placing, breast board assembling and drainage of the drainage main pipe/branch pipe, construction flow guiding of the dredging and overhauling channel section can be achieved, and operation is efficient; the problems that an existing urban channel embankment retaining wall structure is single in function, channel section desilting, overhauling and flow guiding are difficult, and cost is high are effectively solved.
本发明公开了一种城市渠道堤防挡墙结构及施工方法，挡墙结构包括堤防、挡水系统和排水系统；堤防包括重力式挡墙和混凝土底板，堤防包括重力式挡墙和混凝土底板，重力式挡墙为直角梯形断面，迎水侧垂直，混凝土底板顶部为水平面，承载重力式挡墙，迎水侧加厚，堤防设在渠道两侧；挡水系统包括至少两组的可移入或移出渠道以通断水流的栏板，两组栏板与堤防构成的围挡空间作为施工区域；排水系统包括排水干管和排水支管，排水干管沿着重力式挡墙的背水侧坡脚通长布置，位于混凝土底板顶部，排水支管位于混凝土底板顶部，一端与渠道连通，另一端接入排水干管，排水支管的前部均设置门槽和能够沿着门槽上下滑动的闸门，通过启闭闸门使排水系统启闭，至少两组的栏板外侧均设置排水支管分别作为进水端和出水端。本发明采用装配式挡水系统与预埋排水系统，可快速组装和施工；通过闸门提放、栏板装配与排水干管/支管引流，即可实现清淤检修渠段的施工导流，运行高效；有效解决现有城市渠道堤防挡墙结构功能单一，渠段清淤检修导流困难且成本高的难题。
