)高計(jì)算出下游的水面標(biāo)高，管內(nèi)底的標(biāo)高也是一樣。相鄰的管段的管徑不同的話，可以使用管頂平接的方式，管徑相同的話，可以使用水面平接的方式。在水力計(jì)算的時候，需要留意幾個小地方：在選擇控制點(diǎn)時需要細(xì)心。在計(jì)算設(shè)計(jì)管段的坡度時需要細(xì)心。污水從上游往下游流去時，設(shè)計(jì)流量一般會慢慢變大，設(shè)計(jì)流速也會對應(yīng)的變大。但假若設(shè)計(jì)流量保持不變的話，管段內(nèi)的設(shè)計(jì)流速也不能變小。設(shè)計(jì)流量慢慢變大的話，設(shè)計(jì)管徑也應(yīng)該相對應(yīng)的慢慢增加。假若設(shè)計(jì)流量保持不變的話，管段的管徑也不能減小，當(dāng)坡度小的管道與坡度大的在上下游相連時，管徑也可以稍稍減少，減少的范圍應(yīng)在50~100mm之間。為能夠減少當(dāng)水流通過檢查井時的局部水損，井底在呈直線的管線上需要嚴(yán)格的設(shè)置成直線，轉(zhuǎn)彎的位置則需要設(shè)置成均勻的曲線。污水干管水力計(jì)算如表4-3表4表4-3污水干管水力計(jì)算表管段編號管道長度L(m)設(shè)計(jì)流量Q(L/s)管徑D(mm)坡度I流速v(m/s)充滿度降落量I*L(m)標(biāo)高(m)埋深(m)h/Dh(m)地面水面管內(nèi)底上端下端上端下端上端下端上端下端1-2263.599.813000.00160.600.280.080.444.474.342.572.142.492.051.982.292-3263.7911.893000.00140.600.320.100.384.344.172.141.762.041.662.302.5112-3355.488.593000.00180.600.260.080.664.434.172.531.872.451.791.982.383-4345.9023.143000.00090.600.540.160.314.173.931.761.451.601.292.572.6413-14262.098.303000.00190.600.250.080.504.224.072.321.822.241.741.982.3314-4262.098.303000.00190.600.250.080.504.073.931.821.321.741.242.332.694-5443.7532.883500.00070.600.550.190.313.933.511.321.011.120.812.812.7015-16247.108.663000.00180.600.260.080.463.823.571.921.461.841.381.982.1916-5247.1012.833000.00130.600.340.100.333.573.511.461.131.361.032.212.485-6393.2746.404000.00060.600.590.240.223.513.331.010.790.770.552.742.7817-6444.899.323000.00170.600.270.080.773.463.331.560.791.480.711.982.6218-6341.6510.093000.00160.600.290.090.553.153.331.260.701.170.621.982.716-7228.0276.345000.00040.600.620.310.093.333.250.700.610.390.302.942.957-8312.3191.385000.00040.600.610.310.113.253.080.610.500.300.192.952.8919-20271.866.803000.00220.600.220.070.614.174.132.261.652.191.581.982.5520-21271.869.123000.00170.600.270.080.484.134.121.651.171.571.082.563.0425-21380.563.723000.00300.560.150.051.154.414.122.481.322.431.281.982.8421-22344.7316.913000.00110.600.420.130.384.123.741.170.791.040.663.083.0826-27270.2512.663000.00130.600.340.100.373.913.832.031.661.931.561.982.2727-22270.2523.313000.00090.600.540.160.243.833.741.661.431.501.262.332.4822-23147.3245.944000.00060.600.590.230.083.743.550.790.700.550.473.193.08管段編號管段編號管道長度L(m)設(shè)計(jì)流量Q(L/s)管徑D(mm)坡度I流速v(m/s)充滿度降落量I*L(m)標(biāo)高(m)埋深(m)h/Dh(m)地面水面管內(nèi)底上端下端上端下端上端下端上端下端30-23239.7616.983000.00110.600.420.130.263.523.551.671.401.541.281.982.2723-24305.9239.673500.00060.600.650.230.193.553.360.700.510.480.283.073.0828-29222.0210.443000.00160.600.290.090.353.503.471.611.261.521.171.982.3029-24312.1414.843000.00120.600.380.110.383.473.361.260.881.140.762.332.6031-24260.3023.513000.00090.600.540.160.233.313.361.491.261.331.101.982.2624-8393.0680.515000.00040.600.650.320.153.363.080.510.360.190.033.173.0532-8354.873.013000.00300.530.140.041.082.843.080.90-0.180.86-0.221.983.308-9347.30177.397500.00020.600.630.480.083.083.03-0.18-0.26-0.65-0.733.733.7642-9385.465.013000.00280.600.180.051.112.703.030.77-0.340.72-0.391.983.429-10235.75206.438000.00020.600.650.520.053.033.01-0.34-0.39-0.86-0.903.893.9133-34287.4810.283000.00160.600.290.090.464.124.102.231.772.141.681.982.4234-35287.4813.753000.00130.600.360.110.374.104.051.771.401.661.292.442.7639-35310.616.303000.00240.600.210.060.744.234.052.311.572.251.511.982.5435-36252.0426.383500.00080.600.470.160.204.053.771.401.191.241.032.812.7436-37252.0426.383500.00080.600.470.160.203.773.471.190.991.030.832.742.6440-37330.8222.173000.00090.600.520.160.303.523.471.701.401.541.241.982.2337-38306.1351.094000.00050.600.640.260.163.473.280.990.830.730.572.742.7141-38311.5210.473000.00160.600.300.090.493.313.281.420.931.330.841.982.4438-10392.1360.584500.00050.600.610.270.183.283.010.830.640.550.372.732.6410-11348.21263.179000.00020.600.650.590.063.012.95-0.39-0.45-0.97-1.043.983.9943-44426.4015.923000.00110.600.400.120.494.053.872.191.702.071.581.982.29管段編號管段編號管道長度L(m)設(shè)計(jì)流量Q(L/s)管徑D(mm)坡度I流速v(m/s)充滿度降落量I*L(m)標(biāo)高(m)埋深(m)h/Dh(m)地面水面管內(nèi)底上端下端上端下端上端下端上端下端44-45468.2323.433000.00090.600.540.160.413.873.441.701.301.541.132.332.3148-45398.1212.183000.00140.600.330.100.563.473.441.591.031.490.931.982.5145-46357.6452.824500.00050.600.540.240.183.443.241.030.850.790.612.652.6349-46368.2837.913500.00060.600.620.220.243.283.241.521.281.301.061.982.1846-47283.0885.685000.00040.600.680.340.113.243.040.850.740.510.402.732.6447-11107.2193.025500.00030.600.620.340.043.042.950.740.700.400.362.642.5911-污水廠32.78348.1110000.00010.600.690.690.012.952.93-0.45-0.45-1.14-1.154.094.081.2雨水管渠系統(tǒng)設(shè)計(jì)1.2.1劃分計(jì)算管段并確定匯水面積在地勢落差不大并且沒有明顯的分水線的區(qū)域，排水流域的劃分可以依據(jù)小區(qū)的街道匯水面積，將每個匯水面積劃分成大概相等。布置時可以充分的利用地形，因地制宜，讓雨水可以在經(jīng)過短距離靠著重力的作用下快速進(jìn)入水體。該區(qū)域地勢的落差不是很大，分水線也沒有特別明顯，劃分排水流域的話，可以依據(jù)雨水管道服務(wù)的街坊面積范圍來確定，可以統(tǒng)一劃分成四個流域。因?yàn)楸驹O(shè)計(jì)的地形很有利于排水，所以管道的布置方式使用分散出水口式。為了能夠讓雨水在最短時間內(nèi)排入水體，雨水的干管設(shè)計(jì)盡量等高線垂直的方向一致。雨水的支管設(shè)置在干管的兩旁道路。把相鄰并且相連的兩個檢測井之間的管段定為計(jì)算管段，檢查井從雨水管道的上游到下游進(jìn)行編號。匯水面積的劃分應(yīng)該根據(jù)地勢、管道的布置、匯水面積等情況，但是因?yàn)樵搮^(qū)域的地形較為平坦，所以就可以按照就近排入的原則來進(jìn)行劃分，對每塊面積編號，算出對應(yīng)的面積。1.2
