房地产 -沿江苏东部高速护栏提质升级盐通段施工图设计

二○二一年二月152137465266718192363411342021年东部公司交通安全设施提质升级盐通段对应高速路K1058+848～K1086+053段，其中盐通方向为K1058+848～K1076+109，方向为K1071+525～K1086+053，共14.528km，全长31.789km。于2车速度为120km/h，路基宽度35m，按全封闭、全立交、双向六本项目设计内容主要包括G15沈海高速公路盐通方向K1058+848～K3.1护栏现状4）路基段中分带护栏：采用波形梁护栏，具体规格为3.2护栏改造原则3.3护栏改造方案护栏的设置应能够防止失控车辆冲出路基或越过中央分隔本次路侧路基段护栏设计根据试验段的护栏论证方案，路提升方案和路基段基本一致，具体方案为：现状路侧护栏维持现状，同时在现状立柱），），2)小桥通道段中央分隔带护栏设置Gr3.4波形梁护栏材料及护栏防腐波形梁护栏构件均采用热浸镀锌进行防腐处理，其中螺栓、螺母、垫圈、锚固件等紧栏板外侧的横梁垫片等构件在作热浸镀锌防腐处理后，再作喷塑防腐处理，喷塑处理的钢涂层由热浸镀锌内涂层和静电喷涂聚酯外涂层组成。防腐处理的各涂层的厚度应不低于下-为保证钢构件内涂层和外涂层的总体质量，各涂层实施完比后应符合《公路交通工程(1)波形梁、立柱、端头梁及连接螺栓所用钢材为普通碳素结构钢（Q235其技术(2)拼接波形梁的螺栓采用高强螺栓，其技术条件应符合《低合金高强度结构钢》3.5护栏施工工艺本项目为改造项目，需拆除原有波形梁护栏，再按规范重新打入。原护栏拆除时护栏施工经理，波形梁护栏立柱很难直接打入。因此结合本项目特点，本次路基段护栏立柱施设计要求钻孔，对混凝土表层及孔洞清理干净，并保证该部位干爽不湿，然后将锚固孔洞填满预先调好的环氧树脂粘胶后，再把钢筋插入锚定，保证垂直及设计尺寸。溢出锚固孔3.6其他设施其他设施主要包括轮廓标、百米牌、里程牌、防撞垫，由于其均附着于护栏上，随着为了帮助夜间行驶的车辆清楚地辨认道路线形，在新建护栏连续设置轮廓标。轮廓标48轮廓标沿行车方向左侧为黄色，右侧为白色，轮廓标采用附着式设置于护栏顶部，反本项目的里程编号按现状G15进行编侧护栏上，里程牌与护栏立柱之间通过支撑钢管及抱箍连接或膨胀螺栓连接，里程牌材料采用铝合金板加工而成，表面贴V类反光膜。（3）防撞垫为避免护栏端头对失控车辆造成的伤害，本项目在主线与匝道的分流点处设置TS级可导向防撞垫以吸收碰撞能量，降低车辆的伤害程度。防撞垫箱外贴反光膜，配合出入口标线对车辆进行引导。rrx.5nn27277a335入立27283m翼'Gr-S-aa-.52-S2G-S-2x.5nn27277a335入立27283m翼'Gr-S-aa-.52-S2G-S-2x.x.5n28人28337`TSr7K59+75．K＋483攻栏75．7K59+22.8K59+755.入-332r7K59+75．K＋483攻栏75．7K59+22.8K59+755.入-332.2332K2+K2+.5入28.5292K5+85.3K59+37.入5.8K59+37.K59+3533K+83.3K+537.2-5K+537.2K+5.23n332K+5.2K7.入-5.857.5K33·K33332K2+25.8K+38.入27.22828K5K4+27入.729K4+297K4+293.73aa333K4+297K4+93.7y5++)59+35K59+9.89.77K59+755·K59+75.K5+7K7·K57.K5222K2+7.5K2+253.8.3K7+78通道K8+5K7+78通道K8+5++3m翼贵3323333533m翼贵332333353373839K4+9.7K5+37.K5+38K5+85K5+897.5K5+K5+K+587.K+5K3.K37.K7+3.K7+K7+5.7K7+53.7K7+5.7K7+59.7K7+7K7+7K8+7.K8+7K8+372.8K8+375.8K8+.3K8+5K8+55K9+2K4+93.7K5+37.K5+38K5+89·5K5+87.5K5+K5+9·K+587.8K+58K3.K37K7+37+K7+5.7K7+53.7K7+9K7+5.7K7+59.7K7+7K7+7K8+7·K8+7K8+372.8K8+375.K8+K8+5K8+552728.2.5859.3m翼音33m翼音3m翼音33m翼音3m翼音2.53.3m翼音33.53·2335.233m翼音33m翼音53532333m翼音7833m翼音7857.3m翼贵33m翼贵55525355525355555758592929355353m翼啬33m翼啬.23m翼音33.3m翼音.77.7575.r7r7K72+3K72+8攻兰K72+878.K79.K7+38.34攻栏K7+2K72+3K72+8攻兰K72+878.K79.K7+38.34攻栏K7+2·-r72．2．K72+24通道2．2．K7+848通道++K9+2K9+278K9+75.K9+2K9+278K9+75.389+759.38K9+83.9K9+8K7+38．7K7+37K7+3.7K7+37.7K7+79K7+799K727·K73K7+525.2K7+528.2K73.5K7.5K7+82K7+85.K72+8K72+3K72+8K72+878K759K79.K73+3.3K7+38.3K7+2.9K7+5.9K9+278.K9+75.38攻兰K9+759.38K9+83·237.792333.44.5引53·3.5K7+38．7攻兰K7+38．7攻兰K7+3.7-73·3.793.3977727377577778798882777273775777787988828388588788899K7+79K7+79.93n5K7+528.2K7+528.2333.K7+842．攻.兰K7+842．攻.兰K7+85.227373282827.323.33·3.K74+8K74+8.19.019.0+＋0+16.016.0K1074+076通道29.29.029.010.010.0K1074+518通道12.012.0K1074+678通道10.010.0K1075+108通道12.0181.0112.0181.K1075+436通道668.5668.51232.03m翼墙93.03m翼墙++注注53532333353373839K53532333353373839KKKKKKKKKKKKKKKKKKKKKKKKKKKKKKK5353.77+3777+37.77+.777+2.777+577+55578+7.78+978+79.778+79.779.77+737+7873.7.8+55.8+595.+93m翼音K77+73m翼音5.7K775.73m翼音398.33K773m翼音398.339K77+2.79K77322.K77322.3·K78+3·K78+3m翼音33·29.3m翼音33·29.32·25.233K78+79.72332.25K79+2.25K79+7K79+735KK79+735332332K332332788K8788+5KK8+5858+5K5552535555575855525355555758532323m翼音383.3m翼音383.382.532.535.83·559.235.83·52.2+3.5+3.58+3.5+73.3m翼音3293K83m翼音3293K+3.3m翼音8+78+7.3m翼音8+78+7.8+792.82+352.2+355.2+8.8K8+73K+7.35K+7925出3K2+352出3K2+355.3m翼音3·533m翼音3·5382+2K82+.82+2r7r7·s(n)3E373252325322337.73·52.33·85.83.537.233·533·3538·s(n)3E373252325322337.73·52.33·85.83.537.233·533·353833·529.73·53.237.83·53.23353337233r73K82+K82+7.3-82+7.K82+87.y--5K2+7.4K2+93m翼K2+99K3+24兰8K83+253K8+53入-K3+53.K83+53m翼古7K3+5K3+5.7-7K83+5.7K3+5.772K83+58.7K84+52.入-7K55.K4+2.8y--75K84+24.8K84+243.83m翼音7K84+23.8K84+78入77K4+7K84+73n-78K4+7K4+9.3y8K84+33K85+3入8K5+3K5+3n-82K85+K85+5.2y-83K85+5.2K5+522.23m翼音8K85+522.2K85+9.入-8K5+97.K85.2y--++7K3+23.K32277.止追7.止追3m'G-Saa-2G-S-a-.52G-Saa-2G-Saa-2Gr-Saa-25.8.735.2KKK58+88.35+355.85+755.5+755.5+85552.7用古233K59+75KKKKKKKKG-Saa-2G-S-a-.52G-Saa-2G-Saa-2Gr-Saa-25.8.735.2KKK58+88.35+355.85+755.5+755.5+85552.7用古233K59+75KKKKKKKKK5.5583.53.5.8K59+75789G-Saa-2G-S-aa-.52G-Saa-2G-San-2G-Saa-2Gr-S-a-.52Gr-Saa-258.5.335+57.27.57.K5258572353.5.5+79+8K+85KKKKKKKKK5Gr-Saa-2G-Saa-2Gr-Saa-2G-S-aa-.52Gr-Saa-22.3.522+2+2+7.52+253.83+73+223+38.3+393+8.3+52.7.97.7892222232252272825Gr-Saa-2G-Saa-2Gr-Saa-2G-Saa-2Gr-Saa-2G-S-aa-.52Gr-Saa-22.22.2.222.2K3+KKKKK25293.72527.4+93.75+5+25K5+5G-Saa-23KK5+37.5+3rK5+35K5.8K5+755.K5+75.K5+85K5K+83K+57.2K7.K57.KK+7K+8K2+K2+K2+7.5K2+253.8K3+7K3+22K3+3K3+39K3+K3+5K97K4+93.7K5+K5+2K5+37.K5+87.5Gr-Saa-2552++rrK7+78通道2K7+73K7+7K7+7K8+7.K8+7.K8K7+78通道2K7+73K7+7K7+7K8+7.K8+7.K8+3758K8+5K8+55K5.29298+7.5K8+7.K8+375.87K8+.38K8+5K8+5535358.99.77K8+53.3.32K5+897.5K5+G-S-lna-.525.s33K5+K+58G-Saa-28.53K+598KG-S-ala-.52.55.35KK7+G-Saa-237.5372.3K7+K7+5.7Gr-S.525.37K7+5.7K7+G-Saa-23.338K7+9K7+2--5K7+2539K7+2K7+G-Sa-222K7+K7+5.7G-S.5257.58·K7+5.7K7+7Gr-Saa-293.39.G-San-2Gr-Saa-2G-Sa-2G-Saa-2G-S-aa-.52G-Sa-2G-Sa-2G-Saa-25K+2K+2G-Saa-22253K+278.K+75.38G-San-28.82.5K9+75.3K9+83.9Gr-S-ala-.52.55.55K+83.9K7+37G-Saa-257.258.5K7+37K7+3.7G-S-ala-.52535.357K7+3.7K7+79
