深圳港*******区西作业区集装箱码头工程#5、#6泊位码头护岸及道路堆场工程现浇梁模板专项施工方案版本编号：A-20150310 审核： 编制： *******有限公司深圳港*******区西作业区集装箱码头工程#5、#6泊位码头护岸及道路堆场工程项目部年 月 日一、工程简介： 深圳港*******区西作业区集装箱码头工程合同二(B) #5、#6泊位码头护岸及道路堆场工程为高桩码头结构形式，施工长度为575.4m，共9段,其中标准段为H-L共5段，长60.8m，M-O段为非标准段，长67.2m，P段为非标准段，长69.8m桩形式为：前后排为D1100mm钢管桩，中间排位为D1000mm钢管桩，共5排桩，排距（横向）为7500mm，纵向间距为6400mm，部分桩需做嵌岩或锚锭处理，所有桩内为钢筋混凝土结构；施工工艺为：打桩、桩内处理、现浇纵横梁、预制面板、现浇面层 现浇梁模板的组成为：牛腿、底模、侧模、安全防护设施（安全网，详见附图），所有组成部分均为钢结构或者钢木结构我部拟利用钢结构牛腿（详见附图）作底模的主要支撑基础，所有底模牛腿均焊接在直钢管桩侧面；底模安装好之后在底模边缘安装安全网，整个施工平台成形，底模调整好后进行梁格钢筋绑扎、安装侧模、浇筑混凝土。

其标准段纵横梁每跨（跨中）尺寸如下（单位：mm） ：前后轨道梁：长3200,宽2000横梁：长7500,宽1600纵梁：长6400,宽1200标准段结构图二、依据1、《施工组织设计》2、《深圳港*******区西作业区集装箱码头工程#5、#6泊位码头护岸及道路堆场工程施工图纸》3、规范：《港口工程荷载规范》4、《港口工程施工手册》5、《建筑施工计算手册》三、梁模板的安装拆除1、制作及安装装成形的底模板按照图纸要求制作完成并验收合格后方可运抵现场进行吊装，吊装过程中先安装轨道梁、纵梁底模板再安装横梁底模板，横梁底模压在纵梁和轨道梁底模上所有模板吊装完成完成后，由测量放线，底模中轴线及标高，根据测量放线进行底模板调整，然后在模板原木方上钉18mm厚夹板，夹板尺寸同梁底尺寸；所有桩顶位置需在现场进行桩周模板拼装，桩周模板尺寸见图纸，桩周底模板标高低于梁底模板5cm；最后将所有底模板满铺透水模板布侧模板顶面也需钉夹板及透水模板布，此工作在岸上完成后方可进行侧模板吊装，调试并经自检合格后，侧模顶用对拉螺栓连接，底部需收紧顶脚螺栓，使之固定2、模板拆除在砼强度达到设计强度后，吊机或起重船先拆除侧模板。

再把底模用法蓝螺丝及拉杆将底模反吊在梁顶，割去桩上焊接的牛腿，把底模支架放低再用吊机或起重船吊住底模，松开法蓝螺丝，将底模从梁侧面吊出先拆纵梁和轨道梁底模，最后拆横梁底模 底模平面布置图3、施工设备设备名称型号数量备注履带式起重机250吨1起重船50吨1工作船、交通船13.1履带式起重机主臂起重性能表，单位：吨主臂长度（m）幅度(m)51545760636669727578814.5567891079.5/111271.871.370.462.9/1357.7/131459.959.358.657.957.050.444.338.8/1533.8/151651.150.549.849.348.648.143.138.133.229.524.9/171844.243.743.242.642.141.640.936.232.028.523.92038.938.437.937.436.836.335.635.130.927.623.12234.534.233.533.032.431.931.430.830.126.522.32430.830.530.029.428.928.427.927.326.825.521.62627.727.326.826.525.925.424.924.323.823.320.72825.024.924.323.823.322.922.421.921.420.820.03022.622.622.121.721.020.720.119.819.218.718.23220.720.520.119.819.218.718.217.817.316.816.43418.918.718.418.017.517.116.616.115.715.214.93617.317.117.016.415.915.615.014.714.213.813.33815.915.915.615.214.714.313.813.412.912.612.04014.714.714.314.013.413.112.612.211.711.310.84213.613.413.312.912.412.011.511.210.610.39.94412.612.612.211.911.311.010.610.19.89.48.94612.0/4511.511.311.010.510.19.89.28.98.58.04810.810.510.39.89.48.98.58.07.67.3509.89.48.98.58.27.87.36.96.6528.78.38.07.57.16.66.25.9548.5/537.67.36.86.46.15.75.2567.16.86.25.95.55.04.7586.25.75.45.04.54.1605.24.84.54.13.6625.0/614.34.03.63.3644.1/633.63.12.7663.12.72.4682.42.0702.2/691.7721.5/71倍率76655443332主臂长度（m）幅度(m)51545760636669727578814.5567891079.5/111271.871.370.462.9/1357.7/131459.959.358.657.957.050.444.338.8/1533.8/151651.150.549.849.348.648.143.138.133.229.524.9/171844.243.743.242.642.141.640.936.232.028.523.92038.938.437.937.436.836.335.635.130.927.623.12234.534.233.533.032.431.931.430.830.126.522.32430.830.530.029.428.928.427.927.326.825.521.62627.727.326.826.525.925.424.924.323.823.320.72825.024.924.323.823.322.922.421.921.420.820.03022.622.622.121.721.020.720.119.819.218.718.23220.720.520.119.819.218.718.217.817.316.816.43418.918.718.418.017.517.116.616.115.715.214.93617.317.117.016.415.915.615.014.714.213.813.33815.915.915.615.214.714.313.813.412.912.612.04014.714.714.314.013.413.112.612.211.711.310.84213.613.413.312.912.412.011.511.210.610.39.94412.612.612.211.911.311.010.610.19.89.48.94612.0/4511.511.311.010.510.19.89.28.98.58.04810.810.510.39.89.48.98.58.。
