The power on water will be supplied mainly depending on selfgenerating, during temporary porting, connection and supply from land will be used, 、施工道路Construction roads從水廠右側(cè)的臨時進場道路的出入口進入，通過引接部分臨時道路到達取水泵房、頂管施工場地，路寬 ，塊石、道渣路基，泥結(jié)碎石路面。Enter from entrance of temporary siteaccessing road, then arrive intake pumps room, jacking pipe construction site by connecting partial temporary roads, the road with is , stones and clinker road base, claybound macadam road face. 20 / 90、棄土場 waste earth yard基坑開挖、沉井下沉、頂管時的棄土通過管道排放于附近的泥漿池進行沉淀，干化后短運出施工場地，用車輛運至棄土區(qū)堆放。泥漿池設于廠區(qū)的臨海側(cè)，距現(xiàn)場約 300 米，用草袋作圍堰，堰體隨棄土增加而加高，泥水經(jīng)沉淀后排入海中。During foundation pit excavation, sunk well sinking, pipe jacking, the wasted earth will be moved to the vicinal slurry pit for depositing, after drying, it will be transport in short distance out of construction site and stacked in waste earth zone by transporting by vehicle. Slurry pit is located on the sea side which is 300m from site, grass bags will be used for cofferdam, weir body will bee higher as waste earth increases, slurry after depositing will be remove into sea. 施工方法及工藝流程Method and process of construction work、施工方法概述 General of construction method 循環(huán)水泵房主要工作內(nèi)容為：基坑開挖、填砂墊層、沉井制作、沉井下沉、沉井封底、上部結(jié)構(gòu)施工。The main work items of circulating water pumps room: foundation pit excavation, sand filling and lining, sunk well building, sunk well sinking, sunk well bottom sealing, upper structure construction. 取水泵房下部構(gòu)筑物擬采用沉井的方法進行施工，為縮短沉井下沉周期，減輕地下水對沉井施工的影響，施工隊伍進場后，首先在設計的泵房位置進行放樣和布置降水深井，降低地下水位，然后進行基坑開挖和砂墊層施工，澆筑素混凝土墊層、砌筑磚胎膜，同期進行鋼筋加工和模板加工。沉井總高度為，分成三次制作，每次制作高度分別為：、6m、7m，三次澆筑結(jié)束并在第一、二次沉井混凝土強度達到設計強度的 100％、第三節(jié)混凝土強度達到21 / 90設計強度的 70%時開始下沉。視現(xiàn)場降水效果，沉井下沉優(yōu)先采用排水法（干式）下沉的工法進行，或采用排水法與不排水法相結(jié)合的方法進行下沉，以減少下沉過程中因地質(zhì)原因所帶來的沙層液化和塌方，加快沉井下沉速度。沉井下沉到位后，如截水、截砂效果良好，采用干封底并澆筑鋼筋混凝土底板。如不具備干封底的條件，采用水下混凝土封底，待封底混凝土強度滿足排水要求后，抽干井內(nèi)積水并澆筑鋼筋混凝土底板，保養(yǎng) 20 小時后開始后續(xù)的頂管設備安裝。Lower structure of intake water pump is planed to be constructed in the way of sunk well, in order to shorten the time of sunk well sinking and reduce effect to sunk well construction, after construction workers enter site, they firstly set out nearby designed location for pumps room and arrange water level lowering well to lower underwater level, then excavate foundation pit and sand lining layer construction, cast plain concrete lining layer and make brick diebleck, meantime fabrication of steel bars and framework will be carried out, the total height of sunk well is , it will be made by three stages respectively at heights of 、6m、7m, when the three pourings are finished and the concrete firstly and secondly poured reaches 100% designed strength, and the third section concrete reaches 70% designed strength, sinking begins, according to effect of water level lowering, water discharging method (dry)will be priority for sunk well sinkin
