Continuous-flow excavation construction method for riverway in limited area
The invention provides a continuous-flow excavation construction method for a riverway in a limited area. The method includes the steps that S1, a drainage ditch is excavated in the riverway along the river direction, so that upstream river water in the riverway can flow along the drainage ditch; S2, earth excavation is conducted on the portions, on the two sides of the drainage ditch, in the riverway, and retaining soil is reserved on the two side edges of the drainage ditch; and S3, after riverway parts on the two sides of the drainage groove are excavated, the river water on the upstream of the upper end of the drainage ditch is cut off, and earth excavation is conducted on the drainage ditch. The continuous-flow excavation construction method for the riverway in the limited area has the beneficial effects that the drainage ditch is formed in the riverway for drainage, so that the problem that a site is limited due to the fact that diversion trenches are formed outside the riverway is solved, and construction is not limited by surrounding environment any more; earth excavation construction is conducted on the two sides of the drainage ditch while the drainage ditch drains the water, so that the riverway excavation efficiency is improved, and the construction period is shortened; and in addition, the drainage ditch is arranged in a segmented mode for earth excavation, and the method is suitable for earth excavation of rivers with long length and large riverway depth.
本发明提供一种受限区河道不断流开挖施工方法，包括以下步骤：S1：在河道内部沿着河流方向开挖排水沟槽，使河道内的上游河水沿着所述排水沟槽流动；S2：在所述排水沟槽两侧的河道内分别进行土方开挖，并在所述排水沟槽的两侧边保留挡土；S3：待所述排水沟槽两侧的河道部分开挖完成，截断所述排水沟槽上端上游的河水，对所述排水沟槽进行土方开挖。本发明的有益效果：通过在河道内设置排水沟槽排水，解决在河道外设置导流槽受限场地的问题，施工不再受周边环境限制；排水沟槽排水的同时在排水沟槽两侧进行土方开挖施工，提高河道开挖效率，节约工期；另外分段设置排水沟槽、进行土方开挖，适用于长度长、河道深度大的河流进行土方开挖。
