Desilting method capable of improving river channel dredging effect
The invention discloses a desilting method capable of improving a river desilting effect, the desilting method comprises the following steps: 1) surveying geologic structures on two banks and the bottom of a river and the length of the river to obtain a BIM model of the river; 2) dividing the river channel into a plurality of areas along the length direction of the river channel; (3) firstly, installing a desilting frame in the most upstream area of the river channel; (4) installing a separation net perpendicular to the water flow direction on one side, close to the downstream, of the most upstream area; (5) extending a sludge suction pipe into each lattice, sucking and conveying sludge away from the river channel through a sludge suction pump, and cleaning the sludge in each lattice in sequence; and (6) taking out the desilting frame and installing in the next area, the cycling steps (3)-(5), and performing desilting on the next river section area till desilting work of the whole river channel is completed. According to the desilting method, the whole river channel is divided into the desilting river channel sections, and the desilting frame structure is arranged, so that the phenomena of pollutant diffusion and silt escape during desilting can be avoided, and the silt removal rate is greatly improved.
本发明公开能够提高河道清淤效果的清淤方法，包括如下步骤：1)勘测河道两岸和河道底部地质结构以及河道长度，获得河道的BIM模型；2)沿着河道长度方向将河道分割成多个区域；3)首先在河道最上游的区域内安装清淤架；4)在所述最上游区域靠下游的一侧设安装与水流方向垂直的隔离网；5)将吸泥管伸入每个框格中，利用吸泥泵将淤泥吸收输送离开河道，依次清理每个框格中的淤泥；6)取出清淤架，安装到下一个区域，循环步骤3)‑5)，进行下一河段区域清淤，直至完成整个河道的清淤工作。本发明的清淤方法，通过对整段河道进行划分清淤河道段并设置清淤架结构，能够避免在清淤时出现污染物扩散、逃淤的现象，大大的提高了淤泥的清除率。
