设计变更说明

设计变据现场实际情况及施工单位建议，通过有关部门及领导研究决定设计需要变更，故提出变更申请建议。一、变更区域项目区南侧角的514亩地块进行（该地块现状为基本农田）。二、变更原由项目区南侧角的514题进行设计变更。经与企业和施工方沟通，将原设计的项目区南侧角的的514资进行变更。三、变更内容1、将原设计的项目区南侧角的的514亩地块核减，变更增加至项目区东侧的团结干渠旁。21-22#1-23#和1-24#1-22#1-23#1-24#管（0.63MPa）增加，DN110PE支管（0.4MPa）增加。排气井增加1座，泄水井减少7座。四、管道水力计算及复核述，具体计算成果详见下表。干（支）管铺设长度（）干管进管道压力口水头选取h（Mpa）毛管数组流量计值水头损失高差口水头h（）支干（）ZGG-0127.6810.6453.321.250.630.400.400.400.630.400.400.400.630.400.400.400.400.400.630.400.400.400.400.630.40FGG-1-0127.8427.6814.0222.5815.8026.8427.8426.8413.6210.3012.6213.6226.8426.8424.8424.8424.8424.8413.8413.8412.1511.9513.1512.0611.7810.0015.809.003.008.006.005.009.009.007.007.007.007.009.006.006.005.003.000.305.5015.80FGG-1-02FGG-1-03ZG-1-07256.00ZG-1-11FGG-1-046.9811.83ZG-1-12584011680640909090FGG-1-051-22#轮265ZG-1-16灌组215225.92225.921801104.0416.407156801136064045.442.83-3-15.803.351.48干（支）管铺设长度（）干管进管道压力口水头选取毛管数组流量计值水头损失高差口水头h（）支干h（Mpa）（）1101101101801101101101801251251251601401402252001251251251251251809015.8011.300.400.400.400.630.400.400.400.630.400.400.400.630.400.40ZG-1-19100FGG-1-0619.03FGG-1-0713.8012.44FGG-1-08ZG-1-2614611680233606401481184023680640ZG-1-27ZGG-0247.7247.7223.78132.491.600.630.400.400.400.400.400.630.40FGG-2-0131.3616.8220.3823.0531.3629.0618.8818.88ZG-2-0116003200640190310430390360200103293.761431144022880640130104002080064010.0015.80ZG-2-059.0011.000.0015.80FGG-2-021-6#轮ZG-2-06灌组211.20211.204.8834.766652801056064042.242.83-4-15.803.353.08干（支）管铺设长度（）干管进管道压力口水头选取毛管数组流量计值水头损失高差口水头h（）支干h（Mpa）（）ZG-2-07ZG-2-08ZG-2-09ZG-2-10FGG-2-03ZG-2-11ZG-2-12ZG-2-13ZG-2-14ZG-2-15ZG-2-16FGG-2-04ZG-2-17ZG-2-18ZG-2-19ZG-2-20ZG-2-21ZG-2-22FGG-2-05ZG-2-23ZG-2-24ZG-2-25ZG-2-2620020020020046035032029026023020546020020020020020020054018517015514015.8017.880.400.400.400.400.630.400.400.400.400.400.400.630.400.400.400.400.400.400.630.400.400.400.4015.8815.8814.8828.9328.9325.2524.6624.1822.7820.5214.8814.8814.8814.8814.8814.8814.8824.7624.2824.7623.3221.95909045.4310.0015.807.007.007.006.004.0011.004.004.004.004.004.004.007.006.007.006.005.0086766831.17909090909038.78615651464880976044808960408081603680736064064064064039.0435.8432.6429.442.832.832.832.83-5-15.8015.8015.8015.803.353.353.353.352.481.971.521.15909090干（支）管铺设长度（）干管进管道压力口水头选取毛管数组流量计值水头损失高差口水头h（）支干h（Mpa）（）4.003.003.007.004.003.005.003.003.003.003.009.002.000.000.000.0016.001.002.002.002.002.000.0015.8020.640.400.400.400.630.400.400.400.400.400.400.400.630.400.400.400.400.630.400.400.400.400.400.4019.3919.1915.8814.8815.8813.8815.8815.8815.8815.8821.1921.1918.7218.3017.9316.5816.5815.3915.0114.7214.4616.22908.1431.0290902002002002003002902752602456302302202001801601359090ZG-2-3590ZG-2-3690FGG-2-071801101101101102001101101101101101104.6034.78ZG-2-378.3440.9276736660534548.6446.7242.2438.4033.9228.802.832.832.832.832.832.83-6-15.8015.8015.8015.8015.8015.803.353.353.353.353.353.351.791.591.210.920.660.42ZG-2-43274.56ZG-2-44ZG-2-45ZG-2-46480096004240848036007200640640640干（支）管铺设长度（）干管进管道压力口水头选取毛管数组流量计值水头损失高差口水头h（）支干h（Mpa）（）0.000.0015.0032.007.001.001.501.001.007.002.002.001.001.009.001.001.000.003.003.009.001.001.0015.8016.030.400.4015.8015.8431.351.251.250.630.400.400.400.400.630.400.400.400.400.630.400.400.400.400.400.630.400.4031.3529.9719.4318.9319.4318.9318.9318.1018.1016.7216.9316.3917.9316.9316.9317.9314.9314.9318.8617.5016.6529.16817331.35245245245370190165259.20ZG-3-13FGG-3-04144.00144.008.1736.03ZG-3-14635550401008064040.3235.202.832.83-7-15.8015.803.353.352.701.85灌组ZG-3-154400880064090干（支）管铺设长度（）干管进管道压力口水头选取毛管数组流量计值水头损失高差口水头h（）支干h（Mpa）（）2.001.000.0054.0010.000.003.001.000.0012.000.001.002.002.000.000.000.0018.008.001.001.001.000.5015.8018.860.400.400.409037.6533.827.67103.321.600.630.400.400.400.400.630.400.400.400.400.400.400.401.250.630.400.400.400.404.936.9337.659090151.049090ZG-3-284590ZG-3-29306.4090ZGG-0452547028528528528522522511011011011019.0818.0922.8763.95FGG-4-01ZG-4-01ZG-4-02ZG-4-03ZG-4-0420.0720.0720.0720.0719.576.029595959576001520064076001520064076001520064076001520064060.8060.8060.8060.802.832.832.832.83-8-15.8015.8015.8015.803.353.353.353.353.273.273.273.27364.80干（支）管铺设长度（）干管进管道压力口水头选取毛管数组流量计值水头损失高差口水头h（）支干h（Mpa）（）1101102251101101101101101102251251251251251250.000.008.001.001.000.001.002.002.006.000.000.000.001.004.0015.8019.070.400.400.630.400.400.400.400.400.400.630.400.400.400.400.4015.8019.0717.5818.9018.3717.5816.3915.1114.6520.1617.6017.6017.6020.1613.604.3913.97464092806404.9219.0860.8060.8060.8090.2460.802.832.832.832.832.8315.8015.8015.8015.8015.803.353.353.353.353.351.801.801.805.361.80285425285141112802256064095760015200640ZG-4-17-9-五、变更前后工程量及投资对比项目所涉变更区域变更前后工程量及投资对比详见下表。变更前单价（元）变更增减变化单价（元）合价万元)设备费建安费设备费建安费设备费建安费设备费建安费建安费设备费建安费第一部分建筑工程-5.46-5.20-5.20m³m³m³9.8914.09-2.14-2.98-0.08-0.250.05C20混凝土管道支墩909.80909.80三管道附属建筑物工程（二）排气井座m³m³m³m³座m³m³m³m³m³5.0068.3361.110.976.0082.0073.331.160.299.8914.090.010.01758.26909.800.020.140.170.01-0.30-0.09-0.12-0.05-0.03-0.029.8914.09758.26909.80204.782.952.697.156.52第二部分机电设备及安装工程14.2114.211.861.8613.3513.351.741.74-0.87-0.87-0.12-0.12泵站工程-
