Lake overflow pollution comprehensive treatment shallow layer connection pretreatment structure and layout method
The invention relates to a shallow connection pretreatment structure for comprehensive treatment of lake overflow pollution and an arrangement method, which is characterized in that an energy dissipation pool is arranged between a water inlet channel and a first water delivery pipe, and a flexible blocking net, a rigid blocking plate and a pipe orifice baffle are arranged in the energy dissipation pool; a sand setting well is arranged at the joint of the first water conveying pipe and the second water conveying pipe, and an arc-shaped sand blocking baffle is arranged at a pipe opening of the second water conveying pipe; a slurry control bag and a closed grouting body are arranged at the joint of the sand setting well and the first water conveying pipe; water is supplied to the position adjusting water tank through the first water supply pipe, the flexible blanket is driven to move along the sealing cover sliding groove, and then settled sand is blown through the sand washing nozzle and discharged through the sand inlet and the sand pumping pipe; the well lid connecting pipe and the first supporting beam are sequentially welded to the lower surface of the shaft sealing cover, the second supporting beam is driven by the position adjusting bag to be supported on the shaft wall supporting pier, and the second supporting beam is returned through the supporting beam returning rib. The impurity intercepting quality can be improved, the sand setting effect is improved, and the shaft sealing performance is improved.
本申请涉及沿湖溢流污染综合治理浅层衔接预处理结构及布设方法，其特征在于：在进水渠道与第一输水管之间设置消能池，并在消能池内设置柔性拦网、刚性拦板和管口挡板；在第一输水管和第二输水管相接处设置沉砂井，并在第二输水管的管口处设置圆弧形拦砂挡板；在沉砂井与第一输水管相接处设置控浆囊袋及封闭注浆体；先通过第一供水管项调位水槽供水，带动柔性铺盖沿封盖滑槽移动，再通过冲砂喷头吹动沉砂，使沉砂经进砂口及抽砂管排除；在井筒封盖的下表面依次焊接井盖连管和第一撑梁，并通过调位囊袋带动第二撑梁支撑于井壁撑墩上，通过撑梁回位筋实现第二撑梁回位。本发明可提升杂物拦截质量、改善沉砂效果、提高井筒封盖性能。
