【图文讲解】桥梁预制混凝土柱和盖梁技术，施工第一线的干货！
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><strong style="color: blue;"><span style="color: green;">一、预制混凝土柱和盖梁的特点</span></strong></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">1）施工速度快，产品质量好，表面光洁度高，能达到清水混凝土的装饰效果，使结构与建筑统一协调。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">2）工厂化生产节能，有利于环保，降低现场施工的噪音。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">3）结构的整体性能较差，不适用于抗震要求较高的建筑。</span></p>

<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><strong style="color: blue;"><span style="color: green;">三、预制混凝土柱安装</span></strong></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><strong style="color: blue;"><span style="color: green;">1. 承台杯口</span></strong></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">校核坐标位置、标高及杯口几何尺寸、杯口底标高。安装间隙≮80mm。杯口与预制件接触面凿毛处理，预埋件除锈。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><img src="http://mmbiz.qpic.cn/mmbiz/fBQyNvOjqia4ro7TuEva5MUickemKDAfIYrQ5XzpxRNuKqQGZnn75kQL6Ls19tVib8V6icrJsRH6eNBFR80vBsL7lw/640?wx_fmt=png&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 100%; margin-bottom: 20px;"></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><strong style="color: blue;"><span style="color: green;">2. 预制柱验收</span></strong></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">起吊点、各部位尺寸、弹出中线和标高控制线。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><strong style="color: blue;"><span style="color: green;">3. 运输</span></strong></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">支垫位置符合设计要求。路线、交通协调等。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><strong style="color: blue;"><span style="color: green;">4. 预制混凝土柱安装、固定</span></strong></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">1）汽车起重机吊装、人工配合就位。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">2）吊起后对准轴线位置垂直下放到杯口内，在易损部位垫木板或橡胶垫。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">3）准确就位后用硬木楔或者钢楔固定，加斜撑、斜拉杆，保持柱体稳定后摘钩。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><img src="http://mmbiz.qpic.cn/mmbiz/fBQyNvOjqia4ro7TuEva5MUickemKDAfIYjZib8VKxQdibibeWibU2U1HJ3Vesicp0Hdzv8rKfoJ41ibwuYcIwIzQV14nA/640?wx_fmt=png&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 100%; margin-bottom: 20px;"></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><img src="http://mmbiz.qpic.cn/mmbiz/fBQyNvOjqia4ro7TuEva5MUickemKDAfIYY1b6uiczqNFRdgrvf76SficeAcQANq2e0OrKhexdfib0rSfowuczTpcFQ/640?wx_fmt=png&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 100%; margin-bottom: 20px;"></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><strong style="color: blue;"><span style="color: green;">5. 杯口混凝土浇筑</span></strong></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">安装后即时浇筑杯口混凝土（豆石混凝土），待混凝土硬化后拆除楔子，楔坑补浇二次混凝土，强度达到75%后方可拆除斜撑；</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">如预制混凝土柱上还安装预制盖梁，则待盖梁安装完成后才拆除斜撑。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><strong style="color: blue;"><span style="color: green;">6. 冬、雨期施工</span></strong></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">1）杯口内有积雪、积水等，安装前清理干净。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">2）冬期大风及降雪天气不进行安装施工。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">3）冬期对杯口混凝土进行保温措施。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">4）雨期施工做好排水措施。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><strong style="color: blue;"><span style="color: green;">7. 检查项目</span></strong></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">1）成品外观、尺寸等，出厂合格证。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">2）插入基座深度，符合设计要求。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">3）混凝土强度、垂直度、高程等。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><strong style="color: blue;"><span style="color: green;">四、预制混凝土盖梁安装</span></strong></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">1）预制盖梁安装前，应对接头混凝土面凿毛处理，设埋件时应除锈。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">2）在墩台柱上安装预制盖梁时，应对墩台柱进行固定和支撑，确保稳定。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">3）盖粱就位时，应检查轴线和各部尺寸，确认合格后方可固定，并浇筑接头混凝土。接头混凝土达到设计强度后，方可卸除临时固定设施。</span></p>

<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><strong style="color: blue;"><span style="color: green;">五、施工注意事项</span></strong></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">1）运输、吊装应编制专项施工方案。施工前进行 安全技术交底。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">2）吊装、运输作业人员经过培训，持证上岗。</span></p><span style="color: green;"><strong style="color: blue;"><span style="color: green;">关注我们</span></strong></span><span style="color: green;"><strong style="color: blue;">分享：</strong></span>
