221.1管網定線1.1.1布置原則輸配水管（渠）的線路應盡量做到距離短、坡度小、預算少、造價經濟、減少拆遷、少占良田、保護環(huán)境。輸配水管（渠）的走向和位置應符合城市和工業(yè)企業(yè)的規(guī)劃要求，并盡可能沿當前道路或規(guī)劃道路敷設，以利于施工和維護。輸配水管（渠）應盡量避免穿越特殊地形（河谷、山脊、沼澤、重要鐵路和泄洪地區(qū)），并注意避開滑坡、塌方以及發(fā)生泥石流和高侵蝕性土壤地區(qū)。輸配水管（渠）應充分利用水位高差，當條件許可時優(yōu)先考慮重力輸水。如為地形所限須加壓輸水時，應根據設備和管材選用情況，通過技術經濟比較確定分壓級數。輸配水管線的選擇應按照城市規(guī)劃布置，考慮近、遠期結合和分期實施的可能。1.1.2輸配水管渠定線的一般要求沿現有或規(guī)劃道路敷設、縮短管線的長度，避開毒害物污染區(qū)以及地質斷層、滑坡、泥石流等不良地質構造處；干管的延伸方向應當和送水泵站輸水到水池、水塔，大用戶的水流方向一致；以水流方向為基準，以最短的距離布置一條或數條干管，干管應從水量較大的街區(qū)通過，但避免穿越高級路面和重要街道；根據街區(qū)情況，干管的間距宜采用500~800m,干管之間的聯(lián)絡管間距考慮為800~1000m；管網一般布置為環(huán)狀網，在允許間斷供水時可布置成樹狀網，但應考慮以后發(fā)展為環(huán)狀網的可能；對于供水范圍內大的配水管網或水廠與主供水區(qū)距離較遠的管網，應考慮是否增設水量調節(jié)措施；1.2取水方案比較本次工程初步設計擬定兩套方案：方案1：取水廠位于上游，距離取水點較近，干管橫向延伸，連接管縱向延伸，大用戶位于其干管延伸方向，整個管網有25個環(huán)組成，管線總長度較短。方案2：取水廠位于上游，距離城市管網較近，但是距離取水點較遠，干管縱向延伸，連接管橫向延伸，大用戶在其干管延伸方向。整個管網有29個基環(huán)，管線總長度大于方案1。綜合考慮后為了避免水源受到污染，故水廠應盡量設置在上游，干管之間應盡量平行，防止出現回流水，保證供水的穩(wěn)定及施工的方便。故選擇方案A。圖4-1輸水管網定線方案1圖4-2輸水管網定線方案B1.3水力計算1.3.1比流量計算對各管段節(jié)點進行編號，利用CAD量取各管段的長度并計算，結果如下表4-1各管段長度管段管段長度計算長度管段管段長度計算長度1-2651325.51-69669662-37183597-149949943-4963481.58-139829824-57083549-129639635-66496495-158624316-766666615-166556557-869269216-176626628-959359317-186776779-1062462418-1960360310-1196048019-2063863811-12615307.520-2156856812-13599299.521-3981640813-14667333.510-39583291.514-16763389-198388382-59619618-188448447-1783483429-306463236-1685885830-3166433221-2296048031-32549274.522-2357657632-33412205.523-2460960933-34611305.524-2560860834-35611305.525-2675875835-3656056026-2765565536-3749624827-2865665637-38551275.515-28641320.535-38463231.516-2763363327-3061561517-2663363326-3162062018-2596596525-3360360319-2496696624-3461161120-2395395323-3562662328-29601300.522-3658829410-20849849實際長度總和44376計算長度總和36070比流量結果如下：L/(s·m)1.3.2沿線流量計算表4-2各管段沿線流量管段計算長度沿線流量備注管段計算長度沿線流量1-2325.3322.14單側供水1-6966.3765.772-3359.1724.44單側供水7-14993.5567.623-4481.4432.77單側供水8-13981.5966.814-5353.8424.08單側供水9-12963.1165.555-6649.2344.195-15431.19單側供水29.356-7665.5145.2915-16654.6144.557-8692.4647.1316-17661.6845.038-9593.2040.3717-18677.0746.089-10623.7242.4518-19603.3841.0710-11479.8832.66單側供水19-20638.0143.4211-12307.2620.91單側供水20-21568.0738.6612-13299.4320.38單側供水21-39407.85單側供水27.7613-14333.6922.71單側供水10-39291.71單側供水19.851-14338.1223.01單側供水9-19838.3157.052-5961.2765.428-18843.8657.437-17834.3156.7829-30322.89單側供水21.986-16858.0358.4030-31332.03單側供水22.6021-22480.2432.68單側供水31-32274.69單側供水18.7022-23576.0939.2132-33205.81單側供水14.0123-24609.0841.4533-34305.65單側供水20.8024-25607.8441.3734-35305.60單側供水20.8025-26757.9151.5835-36559.6938.0926-27655.2044.5936-37248.01單側供水16.8827-28656.3144.6737-38275.45單側供水18.7515-28320.7221.83單側供水35-38231.61單側供水15.7616-27633.1643.0927-30614.8641.8517-26633.4743.1126-31620.2942.2218-25965.0965.6825-33603.4841.0719-24966.2265.7624-34611.0341.5920-23952.7164.8423-35626.0942.6128-29300.4020.44單側供水22-36293.78單側供水19.9910-20848.7957.771.3.3節(jié)點流量計算在輸水管網中，任意管段的流量由兩部分組成，分別是沿線流量和轉輸流量。任一節(jié)點流量等于流入該管段的其他管段的沿線流量總和的一半。計算公式如下：式中qi——節(jié)點i的流量，L/s;qij——節(jié)點i的相關管段i-j的流量，L/s。節(jié)點編號節(jié)點流量集中流量節(jié)點編號節(jié)點流量集中流量節(jié)點編號節(jié)點流量集中流量155.461456.67117.942787.10256.001547.862843.47328.611695.542921.21428.421795.513043.21581.5218105.133141.756106.8219103.653347.297226.3520102.353441.598105.872149.553558.639102.712245.943637.481076.3723200.44106.383717.811126.792495.083817.261253.422599.8594.483923.811354.9526185.23表4-3各節(jié)點流量1.4管網平差計算1.4.1初分流量進行流量分配的目的是為了初步確定管徑，按照最大時用水量初分流量時滿足以下要求，流向任意節(jié)點流量必須等于流出該節(jié)點的流量，以保持水量平衡。在劃分流量時，首先初步擬定水流方向，然后選擇可以保證整個管網水壓的控制點。一般控制點的位置滿足以下幾點；①距離二級泵站最遠；②地勢較高。1.4.2初定管徑管徑的確定取決于流量和流速。為了防止管網出現事故，流速會有限制：管徑在DN400以下時流速最好在0.6-0.9m/s，管徑在DN400以上時，流速要最好在0.9-1.4m/s。實際情況下的流速還是要根據當地的經濟條件來確定。根據界限流量法確定初分管徑表4-4初分流量與管徑管段編號初分流量初分管徑管段編號初分流量初分管徑2-5694.008005-6355.456005-4192.974502-11000.0010004-3221.395001-6800.009003-2250.005006-16448.637005-15450.0070016-27300.0060015-28190.0045027-30120.0040028-2990.0035030-31145.5840029-3068.7930027-26149.4340028-2756.5330016-17265.2350015-16212.145006-7600.00800管段編號初分流量初分管徑管段編號初分流量初分管徑1-14911.2490026-25150.0040014-7454.5770017-18297.946007-17428.227007-8400.0060017-26300.0060014-13400.0060026-31114.2040013-8160.0545031-33218.035008-18220.18500管段編號初分流量初分管徑管段編號初分流量初分管徑18-25162.0045024-34185.1545025-3380.7435034-35233.5650033-3490.0035024-23130.0040025-24292.8960019-20130.0040018-19250.995009-1091.293508-9234.0050012-1171.5830013-12185.0045011-1044.7925012-960.0030010-2020.002009-19100.0035020-2330.0020019-24117.3440023-3574.93300管段編號初分流量初分管徑管段編號初分流量初分管徑35-3855.0030010-3939.7125038-3737.7425039-2115.9015035-3645.0025021-2216.0015023-2234.4925022-3627.4520020-2117.6520036-3719.932001.4.3最高時平差利用已知的節(jié)點流量對管網進行流量分配，選擇適合的管徑，并進行平差計算。管網共分為39個節(jié)點，25個環(huán)，62個管段。由距離二泵站遠近和地面高程確定控制點為節(jié)點37。根據節(jié)點流量進行流量的初次分配計算閉合差，如不滿足小于0.001，用解環(huán)方程法通過excel表格對環(huán)進行平差計算，使各環(huán)的閉合差均小于0.001即可，平差過程這里取校核后達標的流量及數據。最高時平差結果見表4-5表4-5最高時平差結果環(huán)號管段管長m公稱直徑計算內徑Ch最高時最終平差結果q（L/S）V(m/s)1000ih(m)閉合差Ⅰ2-5961800800120564.951.121.551.490.0005-4708450450-64.740.500.46-0.334-39
