桥梁伸缩缝施工要点.doc

桥梁伸缩缝施工要点：伸缩缝安装采用开槽法：即先铺筑桥面铺装而后开槽安装伸缩缝,砼铺装层控制伸缩缝范围内砼与伸缩缝本身地平整度标高.安装伸缩缝地预留槽,在浇注桥面砼铺装时,用低标号砼填平,其标高和平整度与整体砼铺装一致,并在桥面上画出伸缩缝范围地标记.文档收集自网络，仅用于个人学习桥面沥青砼铺装层完成并经验收合格后,按标记在沥青面层上准确放出伸缩缝边线,再用切割机锯开面层.凿除低标号砼,确保预留槽地深度和宽度,并将伸缩缝范围内地所有砼和低标号砼清除干净,用水清洗.文档收集自网络，仅用于个人学习整体吊装伸缩缝放入预留槽内,以两侧面层地标高为准,控制伸缩缝地标高,中心线符合设计要求.吊装前在槽口底面和侧面涂刷一遍配套专用地TST粘合剂,凉1030分钟,以干为准.将海绵体填入梁端间隙.将熔化后地TST浇入槽底部约5mm厚,同时用刮板将TST涂满槽口两侧,将伸缩缝放入,对中压实（每30cm用钉子固定）.文档收集自网络，仅用于个人学习伸缩缝正确就位后,加以固定,将伸缩缝锚固钢筋与砼梁内预埋钢筋焊接,先焊好伸缩缝一侧,再焊另一侧,每侧均先焊接一半锚固筋.取下伸缩缝夹具,焊接另一半未焊接地锚固钢筋.文档收集自网络，仅用于个人学习在梁端安装模板,模板接缝必须严密不漏浆,浇注预留槽内砼,其顶面与伸缩缝边梁底面齐平.浇注伸缩缝两侧（各50cm宽）桥面砼铺装.砼铺装与伸缩缝顶面和砼路面找平.版权申明本文部分内容，包括文字、图片、以及设计等在网上搜集整理.版权为个人所有This article includes some parts, including text, pictures, and design.
