1、圆管涵变更工程量说明一、(K65+065)端墙帽石:高0.25m宽0.55m长3m双侧合计:0.25×0.55×3×2=0.825m3端墙基础:宽1.05m高4.2m长3m双侧合计:1.05×4.2×3×2=26.46m3八字墙背后片石:上宽1.5m下宽1.8m高2.7m厚度1.4m双侧合计:1/2×(1.5+1.8)×2.7×1.4×2=12.474m3八字墙基础:宽0.4m高2.5m长2.3m双侧合计:0.4×2.5×2.3×2=4.6m3八字墙墙身:宽0.4m高1.27m长2.3m双侧合计:0.4×1.27×2.3×2=2
2、.3368m3铺砌:上宽1.5m下宽2.4m高1.48m厚度0.5m合计:1/2×(1.5+2.4)×1.48×0.5=1.443m3总计:0.825+26.46+12.474+4.6+2.3368+1.443=48.14m3金额:参照清单中砌筑浆砌片石的单价(300元),所以变更金额为48.14×300=14442元二、K64+638八字墙墙身:长2.5m宽0.5m高1.88m双侧合计:2.5×0.5×1.88×2=4.7m3铺砌:上宽2.9m下宽4.6m高2.75m厚度0.5m双侧合计:1/2×(2.9+4.6)×2.75×
3、0.5×2=10.3125m3隔水墙:长5.5m宽0.55m高0.5m双侧合计:5.5×0.55×0.5×2=3.025m3八字墙基础:长2.4m宽2.5m高3m双侧合计:3×2.5×2.4×2=36m3端墙墙身:长3.95m宽1.3m高5m双侧合计:5×3.95×1.3×2=51.35m3端墙帽石:长3.95m宽0.5m高0.5m双侧合计:3.95×0.5×0.5×2=1.975m3总计:4.7+10.3125+3.025+36+51.35+1.975=107.36m3金额:参照清单中砌筑浆砌片石的单价(300元),所以变更金
4、额为107.36×300=32208元三、K64+885进水口左侧墙:1.长3m×高1.23m×宽0.4m=1.476m32.长4.4m×高1.45m×宽0.4m=2.55m3进水口右侧墙:长6m×高1.23m×宽0.4m=2.952m3进水口铺砌:长3m×铺砌厚度0.4m×宽0.6m=0.72m3管涵入水口左侧墙:长2.4m×高1.5m×宽0.4m=1.44m3管涵入水口左侧墙:长2m×高2m×宽0.4m=1.6m3管涵帽石:长2m×高1m×宽0.5m=1m3管涵上游集水口铺砌因是不规则图形,由三个梯形计算出面积,铺砌厚度0.
5、3m计算式如下:(上顶0.9m+下底2.9m)×1.5=5.7m2(上顶1.6m+下底2.9m)×1.25=5.625m2(上顶2m+下底0.6m)×1.45=3.77m2(5.7+5.625+3.77)×0.3m=4.529m3总计:1.476+2.55+2.952+0.72+1.44+1.6+1+4.529=16.267m3金额:参照清单中砌筑浆砌片石的单价(300元),所以变更金额为16.267×300=4880.1元
