厚钢板铺设，侧模采用6mm 厚钢板及型钢制作，保证几何尺寸准确，表面平整光滑，形状准确、不漏浆， 有足够的刚度，各接缝严密不漏浆，且便于折装。共制作中、边梁用模板4 套。根据设计要求，底座跨中向下设置1.7cm 的预拱度。 模板施工：施工时，两侧模间及侧模与底模之间的缝隙用橡胶条密封。 模板间用螺栓连接，底角用对拉螺栓把两侧模与底模夹紧，防止漏浆。两侧模 用拉筋穿于两侧模上方的预置环中，用以控制梁板的宽度。模板表面涂脱模剂， 施工完成后，马上清理模板表面的砼，以确保模板的表面光洁与平整。 立模、拆模采用龙门吊进行。因为模板属于大面积、小厚度钢结构，侧 向刚度不大，在拆除、吊装时，应采取有效措施防止模板发生塑性变形。 为防止内芯模上浮，每隔5m 设一道压杆，压杆采用12#槽钢拼装。 内模拆除时间视气温而定，一般为浇筑砼后 812 小时；外侧模板一般 超过12 小时方可拆模。 d上部构造及安装施工技术方案on the sleepers, checked by qualified fitters. 4.1.12.2.3 after winding up the fuel tank of the iron core, should be checked immediately and have someone recording the

在预制厂集中下料，加工半成品，在台座地板上绑扎好底腹板钢筋后支设箱梁外侧模板并经检查合格按要求安放好波纹管，张拉锚座。每片预制箱梁底板设置4 个直径为100mm 通气孔，如通气孔的位置与普通钢筋发生干扰，可适当调整普通钢筋的位置，但不应削弱截面钢筋数量。预应力钢绞线束预留孔道管道采用波纹管成孔，并在波纹管内再穿一根同径塑料管，随混凝土浇筑过程中来回缓慢抽动塑料管，确保管道畅通。安装时根据钢束坐标位置，并用井字形定位钢筋固定在钢筋骨架上，定位钢筋间距随着坐标变换，直线段70cm 一 道，弯曲段40cm 一道；波纹管套接时，承插长度不小于20cm，接头用防水胶 布缠裹3 层以上，波纹管伸入锚垫板喇叭管内长度应不小于5cm。验收合格后， 安放内模，绑扎顶板钢筋及护栏、伸缩缝、泄水管等附属设施预埋件的安装， 预留负弯槽口，安放负弯矩预埋波纹管，经第二次验收检查合格后，方可浇注 混凝土。预留孔道内不得进入泥浆及杂物，端头用木塞护防。 d上部构造及安装施工技术方案on the sleepers, checked by qualified fitters.

米时，为防止端部水泥浆集中，应从另一端开始向回浇注合拢。当砼浇注到顶部梁高后，用插入式振动器振捣密实后再用平板振动器拖振两遍，使砼表面平整，顶板砼振实后，用木搓板找平，初凝前进行拉毛处理， 并应预留吊绳穿孔。 浇注砼时除遵守普通砼施工的规定外，尚需注意以下几点： d上部构造及安装施工技术方案on the sleepers, checked by qualified fitters.
