High-embankment rapid closure construction method for disaster relief and emergency rescue in flood season
The invention discloses a high-embankment rapid closure construction method for disaster relief and emergency rescue in a flood season, and belongs to the technical field of water conservancy projects. Comprising the following steps that S1, the spur dike is temporarily hit on the upstream; s2, the embankment is advanced from the two sides in advance; s3, high-strength throwing and filling are conducted on the two sides of the closure gap; s4, building stones in a triangular area at the front end of the embankment are used for rapid closing And S5, the embankment is filled to the designed elevation. According to the method, the temporary water stopping and flow dividing spur dike is additionally arranged on the upstream of the river, the water level of a main riverbed at the position is raised, the flow dividing flow is increased, the closure flow is reduced, and the difficulty of large flow, high flow speed and rapid closure in the flood season is reduced; under the condition that no diversion measure is taken in a low-lying place, the high embankment is used for intercepting and raising the riverbed water level, so that water flow is switched to flow through the area according to a preset path, rapid diversion in the flood season is achieved, and conditions are created for rescue and recovery of the water damage area.
本发明公开了一种用于汛期救灾抢险的高戗堤快速截流施工方法，属于水利工程技术领域；包括以下步骤：S1、上游临时雍水丁坝；S2、戗堤自两侧预先推进；S3、龙口两侧进行高强度抛填；S4、利用戗堤前端三角区石料快速合拢；S5、戗堤填筑至设计高程。本发明，在河流上游增加临时雍水分流丁坝，抬高此处主河床水位、增大了分流流量、减少了合拢流量，降低汛期大流量、高流速、快速合拢的难度；在低洼处无导流措施的情况下，利用高戗堤截流，抬高河床水位、使水流按照预定路径切换流经区域，实现汛期快速导流、为水毁区域抢险恢复创造条件。
