Reversing hydraulic reclamation method for rapidly discharging sludge in sand-mixed sludge soil
The invention relates to a switching hydraulic reclamation method for rapidly discharging sludge in sand-mixed sludge soil. Comprising the following steps that 1, a switching hydraulic reclamation facility is constructed in a bog; 2, a main pipeline gate valve is opened, an auxiliary pipeline gate valve is closed, the cutter suction dredger carries out hydraulic filling on mud into the mud pond area through a mud conveying pipeline, a hydraulic filling main pipeline and all main blowing pipes, and the hydraulic filling duration is m; 3, the main pipeline gate valve is closed, the auxiliary pipeline gate valve is opened, the cutter suction dredger blows water into the cofferdam area through the slurry conveying pipeline, the water blowing auxiliary pipeline and the auxiliary blowing pipe, sludge is discharged from the drainage opening, and the water blowing duration is n; and 4, the step 2 and the step 3 are repeated for main and auxiliary pipeline switching hydraulic reclamation. According to the switching hydraulic reclamation method for rapidly discharging the sludge in the sand-mixed mucky soil, the sludge component in the sand-mixed mucky soil can be rapidly discharged, and the problem that the mucky soil is difficult to remove in a current hydraulic reclamation project is solved.
本发明涉及一种用于快速排出砂混淤泥质土中淤泥的倒换吹填方法。包括以下步骤，步骤1：在泥塘内构建倒换吹填设施；步骤2：打开主管线闸阀并关闭副管线闸阀，绞吸挖泥船通过泥浆输送管线、吹填主管线和各主吹管向泥塘区域内吹填泥浆，吹填持续时间为m；步骤3：关闭主管线闸阀并打开副管线闸阀，绞吸挖泥船通过泥浆输送管线、吹水副管线和副吹管向围埝区域内吹水，令淤泥从泄水口排出，吹水持续时间为n；步骤4：重复步骤2和步骤3进行主副管线倒换吹填。本发明提供了一种用于快速排出砂混淤泥质土中淤泥的倒换吹填方法，本方法能够快速排出砂混淤泥质土中的淤泥成分，解决了当前吹填工程中淤泥质土难以清除的问题。
