水库达标加固工程大坝灌浆施工总结

水库达标加固工程大坝灌浆施工总结括坝基帷幕灌浆；坝体劈裂式灌浆;和坝体岸坡段的充填式灌浆.目的是减少或阻止坝基，坝体的渗漏,降低坝体浸润线，消除多解决坝体渗透稳定问题.该分部工程于2008年4月20日开工，我公司接受该项施工任务后,组织有关人员认真地阅读设计本次施工全部机械总装机用电量80千瓦，同时使用机率60%：输电总线按50千瓦需求计算。选用70平方毫铺设，从坝后电站专用变压台至坝顶中点，设总电箱。再由总电箱向坝体两端分两路送电。沿坝体全长每20米设一电线杆，每40米设一分电箱：各分电箱所在桩号分别为0+80，0+120，0+160，0+200，0+240；以满足各机械台班在坝体全长各施工点本次施工包括坝基帷幕灌浆，坝体劈裂式灌浆和充填灌浆2、灌浆泵：BW160型三缸中压泥浆泵三台，流量7.2-9立4、S-2dn6/3泥浆泵2台：流量6立方米/小时，最大压力度以及开孔位置，确保孔位偏差不大于10cm，孔向竖直。坝身洗至回水澄清，孔内残积小于20cm后进行压水试验。先导孔采自下而上分段灌浆法；孔壁高度破碎时采用自上而下分段灌浆没劈裂灌浆注浆管并注入少量纯粘土浆后封闭注浆管口以保持式方法进行施工。灌浆压力通过现场试验后确定为0.3mpa（孔5:13:12:10.8:10.6:1c、灌浆过程的综合控制:包括灌浆压力,每次灌量,灌浆间灌浆起劈压力为0.1-0.3mpa,确定孔口压力控制在0.3mpa左右最大不超过0.45mpa,与设计初定压力范围符合。灌量方面按每量比为:4.3:2.1:1呈现正常的递减情况。坝体最大沉降发生在情况没有发生；至第三序灌浆，坝面出现冒浆,采用开挖锺实处理后继续灌注,至第三序第三次灌浆串孔现象普遍发生,坝肩相本次充填式灌浆针对坝体岸坡段进行.不分孔序,段长控制在10米以内,灌浆次数为五次。灌浆初期孔口三、安全生产:我公司在本工程涉及的安全事宜严格遵守国家的安全法律的指导监督。建立了完善的施工安全保证体系,制定并执行了严孔号桩号孔深每段灌量升总灌量（升）每米灌入量干土灌入量单位干土灌量4段A10-218.413341334158.8659.0578.45A20-1514.07124413442588183.91156.582.19A30-913.72115513452500182.21116.1581.35A40-311.7194411732117180.9904.7177.26A50+310.869.31613.21622.5149.4862.6179.43A60+910.679.81684.31694.1158.8912.1985.49A70+1512.14110511932298189.3925.6276.25A80+2110.2525915861845911.3475.07A90+2710.6486511432008188.72800.4275.23A100+3311.0348513441829165.8736.5666.78A110+3917.021065112411633352196.9864.9150.82A120+4517.0283593312863054179.41329.9678.14A130+5111.82111411352249190.3872.7773.84A140+5710.2231614571773173.5788.7377.17A150+638.613041304151.63590.1668.62A160+696.9812341234176.8608.3687.16A170+755.912141214205.76483.9482.02A180+815.9511851185199.2447.4575.2A190+875.9910741074179.3454.4675.87A200+936.0312231223202.8529.5787.82A210+996.0714041404231.3410.3267.6A220+1056.11963963157.6415.4768A230+1116.9813741374196.85610.1687.42A240+11712.7778314462229174.5902.2370.65A250+12313.52111512152330172.3494970.2A260+1299.4894510842029214786.8183A270+13510.590410441948185.52838.6879.87A280+14111.5292317552678232.51192.14103.5A290+14712.5492411552079165.79894.4971.33A300+15313.5691315352448180.5888.2365.5A310+15916.71140520643469207.61261.0175.46A320+16519.86540140315143457174.11597.4380.43A330+17120.561035107611403251158.11458.0670.92A340+17721.22875160511453625170.81558.373.44A350+18326.888741633113410144655173.22110.2178.5A360+18918.98833160412143651193.31564.4182.42A370+19511.0392511242049185.8874.5679.29A380+2018.3613461346604.5472.31A390+2079.7318151815186.5740.5576.11孔号桩号孔深每段灌量升总灌量（升）每米灌入量干土灌入量单位干土灌量4段A400+21311.08101411842198198.4884.8879.86A410+2197.4415341534206.2538.0472.32A420+22514.0184414942338166.9968.0869.1A430+2316.5912441244188.8540.3482A440+2376.6811361136521.14A450+2437.113031303183.5577.781.37A460+2497.5212271227163.2569.9375.79A470+2558.3719341934231763.6489.63A480+2618.5213441344157.7671.8678.86A490+26714.7113416932827192.31260.6985.76A500+27314.1397412442218156.97973.7868.92A510+2799.112151215133.52575.3563.23A520+2859.111561156127.03567.9461.75B10-1910.298758051680163.27562.3554.65B20-1314.0672511131838130.73719.5751.18B30-713.0573511361871143.37704.4653.98B40-111.046438841527138.32573.1651.92B50+510.527861073185910.52681.1864.75B60+1111.167069041610144.27609.0454.57B70+178.9710331033115.16438.6848.91B80+2310.386858231508145.28542.8352.3B90+2910.777149221636151.9582.3254.07B100+3511.026758141489135.12530.0448.1B110+4117.027359738142522148.18882.0751.83B120+4711.027348431577143.1543.749.34B130+5311.37149651679148.58573.6250.76B140+599.68984984101.65370.7438.3B150+658.0610651065132.1346257.32B160+716.4410331033160.4413.5864.22B170+775.92844844142.57277.5446.88B180+8310.966849031587144.8577.9852.74B190+896853853142.17282.7847.13B200+956.0410731073177.65339.9856.29B210+1016.09924924151.72333.4454.75B220+1076.4510851085168.22350.154.28B230+1137.24985985136.05374.251.69B240+11913.037448741618124.17552.6642.41B250+1258.8211361136128.8468.2453.09B260+1319.8212251225124.75427.843.56B270+13710.849048421746161.07520.3448B280+14311.869448131757148.15619.652.24孔号桩号孔深每段灌量升总灌量（升）每米灌入量干土灌入量单位干土灌量4段B290+14912.888159731788138.82685.1253.19B300+15514.6184611231969134.77794.1554.36B310+16117.768458747622481139.7908.8351.17B320+16720.1287510249332832140.761182.3758.77B330+17320.7882681410632703130.081082.3952.09B340+17926.448059658948633527133.41496.5456.6B350+18527.192710158838333658134.981522.856.19B360+19115.4690510651970127.4375949.09B370+19710.148957841679165.58587.9157.98B380+2038.8310431043118.12449.5850.92B390+20310.187958531648161.89619.8360.89B400+2159.8811751175118.93515.9552.22B410+22114.298049341738121.62687.0848.08B420+22713.879158881803668.1348.17B430+2336.4511031103361.7856.09B440+2396.8211141114163.34323.9247.5B450+2457.2411441144158.01380.7452.59B460+2517.6611461146149.61352.9646.08B470+2578.412351235147.02419.649.95B480+2638.5812341234143.82422.2449.21B490+26915.359449441888693.0845.15B500+27513.65759941569115.37611.5644.97B510+2819.113331333146.48507.6855.79C10-1712.18383644102784.32287.7223.62C20-1114.39475583105873.52287.3919.97C30-512.3843456399780.53267.4921.61C40+111.1949547496986.6237.721.24C50+710.1844442386785.1721
