挡墙及管涵动增设的汇报

四川正达路桥工程有限公司关于管涵及挡墙增加、变动及滑坡整治施工方案核实情况的汇报国有宣汉县楠竹场青海交通建设监理试验检测咨询有限公司：我公司正在进行宣汉县东乡镇大梁至楠竹场公路改建工程二标段路基开挖、挡墙及管道涵洞施工。2013年1月6日由业主、监理根据现场实际情况核实管涵、挡墙及滑坡整治施工方案作如下增加、变动：1、增设四座管涵：①民房侧需要排水6+298.404（L=8m）；②山水汇集低洼处7+547.766（L=8m）；③山水汇集低洼处10+519（L=8m）；④民房侧需要排水11+333.176（L=16m）。2、为确保现有道路材料运输畅通，保证路面宽度及工程整体使用效果，适当增加涵管长度；3、由于6+000~6+042挡墙基础开挖后地质情况差，原设计高度、厚度尺寸不能满足工程质量要求，增高增厚挡墙施工尺寸。工程量由业主现场代表、监理、施工三方现场实际收方确认；4、K8+485.899~K8+622.591滑坡地段处理方案：将该段山体开挖，道路改线尽量向山体内侧移动。实际完成工程量由业主现场代表、监理、施工三方共同现场测量确定。5、对路基局部需要换填的地段进行块石换填。6、对挡墙、管涵增加变动及滑坡整治方案通过概算共需增加金额556650.14元。现将该情况汇报给你们，敬请业主、监理能尽快落实最终实施意见，以便我方尽快实施，以保证整个工程施工工期。附：宣汉县东乡镇大梁至楠竹场公路改建工程二标段挡墙、管涵及滑坡整治施工方案增加、变动概算表特此报告四川正达路桥工程有限公司宣汉县东乡镇大梁至楠竹场公路改建工程二标段项目部二○一三年一月七日附：宣汉县东乡镇大梁至楠竹场公路改建工程二标段挡墙、管涵及滑坡整治施工方案增加、变动概算表序号桩号工程内容单位工程量合同单价金额（元）备注一K6+000~K6+042挡墙尺寸增高增厚，M7.5浆砌Mu50块石m3214.2251.2753822.0地质情况变化二K8+485.899~K8+622.591山体开挖，路线向山体内侧移动14323.8283245.40滑坡整治1土方开挖m32148.63.317111.862石方开挖m312175.222.68276133.54三需要增设的管涵管径D1000mm174194.49（一）K6+298.40436091.371洞身22881.74土方开挖m311.319.77223.40石方开挖m370.7858.024106.66管道安装m82219.3617754.88C25砼帽石m30.53662.12350.92沥青麻絮沉降缝m22222.94445.882洞口3324.24M7.5浆砌块石边沟跌井m37.43254.131888.19M7.5浆砌片石铺砌m34.33210.64912.07M7.5浆砌块石截水墙m30.52210.88109.66M7.5浆砌片石排水沟m30.88253.05222.68M7.5浆砌块石八字墙身m30.91210.59191.643洞身结合部2305.88M7.5浆砌块石一字墙基础5.22244.81277.86M7.5浆砌块石一字墙身4.88210.661028.024基础7579.51碎石管形基础垫层m36.66227.281513.69C15砼管形基础m311.11521.365792.31M7.5浆砌块石基础m31.34204.11273.51（二）K7+547.76636198.531洞身23011.19土方开挖m312.819.77253.06石方开挖m372.558.024206.45管道安装m82219.3617754.88C25砼帽石m30.53662.12350.92沥青麻絮沉降缝m22222.94445.882洞口3301.95M7.5浆砌块石边沟跌井m37.43254.131865.90M7.5浆砌片石铺砌m34.33210.64912.07M7.5浆砌块石截水墙m30.52210.88109.66M7.5浆砌片石排水沟m30.88253.05222.68M7.5浆砌块石八字墙身m30.91210.59191.643洞身结合部2305.88M7.5浆砌块石一字墙基础5.22244.81277.86M7.5浆砌块石一字墙身4.88210.661028.024基础7579.51碎石管形基础垫层m36.66227.281513.69C15砼管形基础m311.11521.365792.31M7.5浆砌块石基础m31.34204.11273.51（三）K10+51936310.321洞身23100.69土方开挖m313.619.77268.87石方开挖m373.7758.024280.14管道安装m82219.3617754.88C25砼帽石m30.53662.12350.92沥青麻絮沉降缝m22222.94445.882洞口3324.24M7.5浆砌块石边沟跌井m37.43254.131888.19M7.5浆砌片石铺砌m34.33210.64912.07M7.5浆砌块石截水墙m30.52210.88109.66M7.5浆砌片石排水沟m30.88253.05222.68M7.5浆砌块石八字墙身m30.91210.59191.643洞身结合部2305.88M7.5浆砌块石一字墙基础5.22244.81277.86M7.5浆砌块石一字墙身4.88210.661028.024基础7579.51碎石管形基础垫层m36.66227.281513.69C15砼管形基础m311.11521.365792.31M7.5浆砌块石基础m31.34204.11273.51（四）K13+333.17665594.271洞身45919.78土方开挖m323.719.77468.55石方开挖m3138.458.028029.97管道安装m162219.3635509.76C25砼帽石m30.53662.12350.92沥青麻絮沉降缝m27222.941560.582洞口4779.63M7.5浆砌块石边沟跌井m37.43254.131888.19M7.5浆砌片石铺砌m39.76210.642055.85M7.5浆砌块石截水墙m31.32210.88278.36M7.5浆砌片石排水沟m31.27253.05321.37M7.5浆砌块石八字墙身m31.12210.59235.863洞身结合部2428.91M7.5浆砌块石一字墙基础5.43244.81329.26M7.5浆砌块石一字墙身5.22210.661099.654基础12465.95碎石管形基础垫层m311.34227.282577.36C15砼管形基础m318.18521.369478.33M7.5浆砌块石基础m32.01204.11410.26四需要增加管长的管涵管径D1000mmm10.523303.281K6+578.687原设计7.5m，实际施工需8.0m。m0.52219.361109.682K6+757.788原设计7.5m，实际施工需8.0m。m0.52219.361109.683K7+058.248原设计6.5m，实际施工需7.0m。m0.52219.361109.684K7+316.326原设计6.5m，实际施工需8.0m。m1.52219.363329.045K7+691.946原设计6.5m，实际施工需7.0m。m0.52219.361109.686K8+140原设计7.5m，实际施工需8.0m。m0.52219.361109.687K8+720.277原设计6.5m，实际施工需7.0m。m0.52219.361109.6889+257.914原设计6.5m，实际施工需7.0m。m0.52219.361109.6899+640原设计6.5m，实际施工需8.0m。m1.52219.363329.041010+440原设计6.5m，实际施工需7.0m。m0.52219.361109.6811K11+300原设计6.0m，实际施工需7.0m。m1.02219.362219.3612K11+699.171原设计7.5m，实际施工需8.0m。m0.52219.361109.6813K11+800原设计6.0m，实际施工需8.0m。m2.02219.364438.72五路基需要换填的地段m2950.323.2422084.9716+380~6+39616×1.5m29.026+410~6+42010×1.5m215.036+430~6+45828×1.2m233.646+510~6+55040×1.2m248.056+560~6+57616×1.2m219.366+590~6+60010×1.5m215.076+640~6+66020×1.2m224.086+740~6+76020×1.5m230.096+848~6+86012×（1.0×2）m224.0106+919~6+93516×1.2m219.2117+044~7+07531×1.2m237.2127+252~7+28735×1.2m242.0137+300~7+32525×1.5m237.5147+380~7+435（20+15）×1.5m252.5157+540~7+56424×1.5m236.0168+734~8+83169×1.5m2103.5178+850~8+86010×1.2m212.0188+900~8+91212×1.25m215.0199+276~9+31539×1.3m250.7209+360~9+3666×1.5m29.0219+372~9+39624×1.5m236.0229+542~9+57533×1.5m249.5239+878~9+92042×1.35m256.72410+335~10+38146×1.5m269.02511+280~11+31031×1.0m231.02611+580~11+64363×1.2m275.6六合计一+二+三+四+五元556650.14
