冠诚清淤机械:
清淤主要采用人工清理配合机械运卸的施工方法。
一、施工规划
计划先施工河道,查看河底淤积严重程度,待工程量重新审核认定后再同时安排施工。
二、施工程序
填筑围堰 抽水------吸污泵吸淤泥至罐车运卸------人工清 理渣土(含垃圾、石块)------ 吊运至岸上临时堆放点------ 渣土车外运至卸土点 ------ 河底清淤测量验收合格 ------ 进入下一分段施工
三、施工方法
1、围堰
每一分段施工长度初拟为200~300米左右,围堰采用袋装砂土叠筑,迎水面铺编织布(彩条布)防渗并用袋装砂土压盖,袋装砂土叠筑时须做到排列密实、整齐。围堰顶宽0.6米,两侧边坡1:0.75,围堰高度应比正常高水位高出0.5~1.0米。
2、抽水
采用Φ120污水泵日夜不停地抽水。
3、清理
围堰内水抽干后,先用吸污泵将表层淤泥直接吸到罐车上,运至卸土点堆放;下部渣土(含垃圾、石块)采用人工清理,然后吊运至岸上临时堆放点利用渣土车外运至卸土点 堆放,对于局部工作场地允许的地方直接用反铲挖掘机挖河底淤泥和渣土,渣土车装运至卸土点。 每一分段的河底清理后,须经业主和监理测量验收合格后方可进入下一分段的施工。
4、环境保护与市容卫生
施工中做好日常清洁工作,淤泥按指定地点弃放,不污染堆泥场的环境, 运输渣土过程中,采取有效的措施,防止出现“滴、洒、漏”现象。
Crown-dredging machinery:
Dredging construction methods mainly manual cleaning with mechanical unloading operation.
A construction plan
Plans to start construction of the river, see the river siltation severity of quantities to be identified and then re-examine and arrange construction.
Second, the construction program
------ Cofferdam pumping sewage suction pumping sludge tankers to unload ------ manual cleaning muck (including garbage, stones) ------ lifted ashore temporary dump sites ------ muck truck unloading soil Sinotrans to point ------ ------ river dredging measure of acceptance into the next segment of construction
Third, the construction method
1, cofferdam
The length of each segment at the beginning of construction is proposed for about 200 to 300 meters, using bags of sand stacked cofferdam built, welcoming the shop woven (color of the cloth) and with bags of sand seepage gland, sand bags stacked shall be arranged so that when building dense, neat. Cofferdam top width of 0.6 m, the slope on both sides of 1: 0.75, cofferdam height should be higher than the normal high water level of 0.5 to 1.0 m.
2, pumping
Using Φ120 sewage pump pumping around the clock.
3, clean up
After pumping out the water inside the cofferdam, first with the sewage suction pump sucked directly on the surface of the sludge tank, transported to the unloading point piled earth; the lower muck (including garbage, stones) using manual cleaning, then lifted to shore temporary piling point to the use of muck truck unloading soil Sinotrans point stacking, allow for local workplaces where the direct use of backhoe digging river mud and muck, muck truck to unload the shipment earth point. After each segment of the river clean-up, subject to acceptance of the owner and supervision of measuring construction before entering the next segment after passing.
4, environmental protection and amenity health
Construction work to do daily cleaning, sludge abandoned place at specified locations, do not pollute the environment field heap of mud, sediment transport process, to take effective measures to prevent "drop, spill, leak" phenomenon.
