【正文】 泥漿池設(shè)于廠區(qū)的臨海側(cè)，距現(xiàn)場(chǎng)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。Follow design drawings to do well measure control work, set datum mark and make measurement, positioning and setting out.、物資設(shè)備準(zhǔn)備 Preparation of materials and equipmentA、根據(jù)本工程的工作量、工程進(jìn)度、質(zhì)量要求及現(xiàn)場(chǎng)地域環(huán)境，確定各項(xiàng)施工物資供應(yīng)和設(shè)備供應(yīng)情況。The underwater in most intake holes in the planed site are corrosive to concrete structure, only one intake hole are exceptional, so we suggest to consider it as light corrosion。上述各層分布均不連續(xù)，層厚變化較大。The plant is located at 500m away from the coast of South China Sea which is very near from BINTULU port, transportation distance is about 6km, its topography is flat.、工程地質(zhì)及水文條件 Geological and hydrological conditions、工程地質(zhì) 5 / 90Geological condition該工程現(xiàn)場(chǎng)位于南中國(guó)海邊，現(xiàn)場(chǎng)和周圍環(huán)境為近岸沉積物和沼澤沉積物所覆蓋。The fine silt layers (31)amp。Construction site will be provided by the owner or Party A, including temporary building land and construction working land, about 11000m2 in all.、辦公區(qū) Offices zone由甲方提供并統(tǒng)一安排，位于電廠取水泵房附近，面積約 600m2。 rooms for life in life zone will be mainly leased from local resident which are somewhat far from construction site, the workers will be carried by bus for on/off construction site, women/men toilets will be set up, roads on site will be hardened, rainwater and life sewage will be drained into vicinal water collector after treatment.、施工用水Water for construction work19 / 90沉井、泵房和頂管的生活和施工用水從施工現(xiàn)場(chǎng)附近業(yè)主或甲方提供的接口計(jì)量處，分別用 Φ48PVC 管引接至各用水點(diǎn)控制閥。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 sinking。施工現(xiàn)場(chǎng)設(shè)男女廁所，場(chǎng)內(nèi)地面硬化，雨水、生活污水經(jīng)處理后通過(guò)排水溝排入附近集水溝。Party A shall provide an interface within 100m away from construction site for the water used for construction work, at present, no life water ring work is established, party A shall provide interface as near as possible within life zone, the following part will be on us 14 / 90、臨時(shí)道路 Temporary road現(xiàn)有一條臨時(shí)道路進(jìn)入施工區(qū)域附近，進(jìn)場(chǎng)后需要從該道路引接一條施工道路到達(dá)取水泵房、頂管等施工場(chǎng)地。Buried foundation rock is french gray or clay fine silt offwhite, usually contains thin layer of sandy clay rock. According to the status of weathering, the buried foundation rock is divided into strongly weathered layer（61） and medium weathered layer(62）. 8 / 90Layers （61 ）are mostly weathered into sandy condition, it is hard to take out a plete rock core, normally layer thickness is 。This project is located in BINTULU, Sarawak state, east Malaysia, this extension is to build 2 new residual heat boiler, 1 turbinegenerator unit and relevant accessories based on the original two sets (7 amp。Layer （43）fine silt in high density has very good construction ability, but buried deeply.（51）層粉質(zhì)粘土呈流塑狀態(tài)，具高壓縮性、承載力低的工程特性，其建筑性能差；7 / 90Layer （51）silty clay show fluid condition, it is in the characteristics of high pressibility and low bearing capability, its construction ability is poor.（52）層粉質(zhì)粘土呈軟塑狀態(tài)，具較高壓縮性、承載力低的工程特性，其建筑性能較差；Layer （52）silty clay shows soft plastic condition, it is in the characteristics of high pressibility and low bearing capacity, its construction ability is poor（53）層粉質(zhì)粘土呈可塑狀態(tài)，建筑性能中等；Layer （53）Silty clay shows ductile, its construction ability is medium（54）層粉質(zhì)粘土呈硬塑狀態(tài)，建筑性能較好，但此兩層埋藏較深。而在平面上各個(gè)孔中的地下水位埋藏深度存在著一定差異，最淺 (見(jiàn)于附屬建筑物地段地勘資料 )，最深 (見(jiàn)于循環(huán)水管地段地勘資料)。According to the work quantity, construction progress, quality requirement and regional environment of site to determine supply of materials and equipment, in order to ensure arrival of main materials, revolving materials, framework system and constructing equipment etc.B、各種物資設(shè)備根據(jù)施工和進(jìn)度要求編制供應(yīng)計(jì)劃，及時(shí)供應(yīng)，保證施工生產(chǎn)正常進(jìn)行。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(jìn)行施工，為縮短沉井下沉周期，減輕地下水對(duì)沉井施工的影響，施工隊(duì)伍進(jìn)場(chǎng)后，首先在設(shè)計(jì)的泵房位置進(jìn)行放樣和布置降水深井，降低地下水位，然后進(jìn)行基坑開(kāi)挖和砂墊層施工，澆筑素混凝土墊層、砌筑磚胎膜，同期進(jìn)行鋼筋加工和模板加工。Cables will be used to connect power supply at the interface that the owner or Party A provided to all power using points. power load at intake pumps room, jacking pipes zone is about 550KVA, considering unsaturation and unevenness, the total power requirement will be supplied base on 500KVA.
