船閘工程主要工程量計(jì)算

船閘工程主要工程量計(jì)算土方開挖工程(含引航道)；確定開挖線。根據(jù)邊坡比例，等高線及航道尺寸確定開挖線。取開挖增寬兩邊各為5m，開挖坡度1：2。根據(jù)地形變化，整個(gè)船閘選取20個(gè)斷面分段進(jìn)行概算，其中上引航道5段，下引航道5段，上下導(dǎo)航道各2段，閘室4段，閘室各自分別計(jì)算。詳見圖4。根據(jù)這些典型斷面，分段求出船閘土方開挖量。（詳細(xì)過程見表八）圖4船閘工程量計(jì)算分?jǐn)鄨D2.混凝土工程量根據(jù)混凝土斷面面積大致估算混凝土用量。3.粘土鋪蓋工程量跟混凝土一樣，根據(jù)回填的斷面積大致估算。4.引航道漿砌塊石工程量同樣的，漿砌石也是由船閘的斷面尺寸大致估算。5.土方回填工程量土方回填計(jì)算與開挖計(jì)算相似。確定回填面，按1：2.5坡度回填，同時(shí)回填面預(yù)留5米作為機(jī)械通道或人行道。整個(gè)船閘分段計(jì)算回填量，取典型斷面作回填斷面圖，詳見圖5，計(jì)算回填量。（詳細(xì)過程見表十二）圖5各典型斷面回填斷面圖6.護(hù)坡采用草皮護(hù)坡方式。附：計(jì)算表一工程量計(jì)算表表八挖方量計(jì)算左截面面積計(jì)算表右截面面積計(jì)算表土方量計(jì)算表左截面高度左截面下底計(jì)算寬度左截面上底計(jì)算寬度左截面面積F1右截面下底計(jì)算寬度右截面高度右截面上底計(jì)算寬度右截面面積F1長度土方量總方量上引航道10.5631058826310.25104855.87596.9166784214.53246147.410.2563104855.875639.75102804.37534.6666728777.679.7563102804.375639.3100.2758.8847.537127.319.363100.2758.88639.8102.2809.488062734.49.863102.2809.48639.85102.4814.5954133293.54上導(dǎo)航段9.8563102.4814.595309.5568.2468.905402567031412.139.553068.2468.9053012.479.6679.52105742.125上閘首12.44291.6828.324212.290.8810.0820.0833316452.2716452.27閘室段8.23062.8380.48307.7561352.62561.3333322481.8975819.217.753061352.625307.660.4343.5243.6666715199.177.63060.4343.52308623684114586.1683062368308623686423552下閘首1242907924211.7589769.6252015616.2515616.25下導(dǎo)航段11.753077628.625308.764.8412.38105205.02521445.538.73064.8412.38638.496.6670.323016240.5下游引航道8.46396.6670.32638.7598704.37583.3333357278.962037928.756398704.375639.3100.2758.8871.6666752433.39.363100.2758.88638.797.8699.4871.4166752075.618.76397.8274.05638.195.4641.5249.4166722622.218.16395.4255.15637.994.6622.5244.1666719381.88總工程量為：610684.8表九混凝土計(jì)算位置截面積長度或?qū)挾然炷凉こ塘康装鍌?cè)板閘室段402921014490上閘首398207960下閘首398207960位置底板側(cè)板長度寬度直線段傾斜段上導(dǎo)航段28.521.62010426下導(dǎo)航段28.521.62010426總工程量31262表十漿砌石計(jì)算表位置截面積計(jì)算長度漿砌塊石工程量側(cè)板底板上游引航段4821.230020760下游引航段4821.232022144位置側(cè)板底板側(cè)板長度底板厚度上游導(dǎo)航段24119572.50.42218下游導(dǎo)航段24119572.50.42218總工程量47340表十一粘土鋪蓋回填位置截面積計(jì)算長度/寬度/厚度工程量上引航段137.830041340上導(dǎo)航段左段4952.61287中段7002.61820右段34.524.828下導(dǎo)航段左段4952.61287中段7002.61820右段34.524.828下引航段137.832044096總工程量93306表十二填方計(jì)算位置填土截面積長度總填土工程量扣去粘土鋪蓋后回填總工程量上游引航段489.743014692.296582.9456.41270123230.7下游引航段489.743014692.2102955.1456.41290132358.9閘室段355.3221074617.274617.2上閘首644.612012892.212892.2下閘首617.482012349.612349.6上游導(dǎo)航段510.46105104.615724.8472.76209455.2510105100下游導(dǎo)航段510.46105104.615724.8472.76209455.2510105100總量424152.6330846.6表十三工程量匯總表工程量匯總工程部位開挖量回填量砌石量混凝土量粘土鋪蓋量漿砌石塊上引航道246147.496582.92076041340下引航道203792102955.12214444096閘室75819.2174617.214490上閘首16452.2712892
