Ecological transformation construction method for river bottom of black and odorous water riverway
The invention provides an ecological transformation construction method for the river bottom of a black and odorous water riverway. The ecological transformation construction method comprises the steps that waste water flowing into the riverway is cut off; ecological transformation is carried out on the riverway; after backfill construction on the outer sides of barricades is completed, the riverbottom of the riverway is constructed, multiple grooves are evenly excavated at the river bottom, first water permeable pipes are buried in the grooves, and vertical anti-deposition check valves are arranged in the vertical direction; and after mounting of the vertical anti-deposition check valves is completed, a first coarse sand cushion layer is paved at the river bottom, a bentonite anti-seepage blanket is paved on the first coarse sand cushion layer, a second coarse sand cushion layer is paved on the bentonite anti-seepage blanket, geotechnical cloth is paved on the second coarse sand cushion layer, an ecological gabion is paved on the geotechnical cloth, and the upper ends of the vertical anti-deposition check valves are higher than the upper side face of the ecological gabion. By means of the method, the problem of black and odorous water can be effectively solved, water of the riverway can be prevented from flowing back to the underground space, and the situation that the waterpressure of underground water is too high, and the river bottom and the two sides of the riverway are damaged can be effectively avoided through the anti-deposition check valves.
本发明提出了一种黑臭水体河道河底生态化改造施工方法，包括：对流入河道的污水进行截流；对河道进行生态化改造；在挡墙外侧回填施工完成后，对河道的河底进行施工，在河底均匀的开挖若干沟槽，在沟槽内埋设第一透水管，并沿竖直方向设置竖向防淤积逆止阀；在竖向防淤积逆止阀安装完成后，在河底铺设第一粗砂垫层，在第一粗砂垫层上铺设膨润土防渗毯，在膨润土防渗毯上铺设第二粗砂垫层，在第二粗砂垫层上铺设土工布，在土工布上铺设生态石笼，竖向防淤积逆止阀的上端高于生态石笼的上侧面。本发明的方法能够有效的解决黑臭水体问题，而且可以防止河道水回流至地下，通过防淤积逆止阀能够有效的防止地下水水压过高，对河底及河道两侧造成危害。
