The invention discloses a construction technology for repairing bridge cracks in construction. Carbon fibre cloth is cut according to the size required by the design. Before construction, surface moisture content and ambient temperature of the concrete at the bonded part should be measured, and the loose part of the surface of the strengthened component should be removed until the concrete structure layer is exposed. The prepared binder is evenly applied to the mixing of the parts requiring bonding. On the surface of the condensate, the cut carbon fiber cloth is applied on the base layer coated with the binder. The bottom glue should be uniformly coated on the concrete surface cleaned with acetone, and the special drum is rolled on the surface of the carbon fiber cloth several times along the direction of the fiber. The operation procedure of this process is simple, and it can ensure that the carbon fiber cloth sticks tightly and will not come out in the natural environment. The cracks have been repaired to ensure the service life and safety of the bridge.

建筑施工中桥梁裂缝修补时的施工工艺
本专利技术涉及一种工艺,尤其是涉及一种建筑施工中桥梁裂缝修补时的施工工艺。
技术介绍
桥梁,指架设在江河湖海上,使车辆行人等能顺利通行的建筑物,称为桥。桥梁一般由上部构造、下部结构、支座和附属构造物组成,上部结构又称桥跨结构,是跨越障碍的主要结构;下部结构包括桥台、桥墩和基础;支座为桥跨结构与桥墩或桥台的支承处所设置的传力装置;附属构造物则指桥头搭板、锥形护坡、护岸、导流工程等。桥梁实际上就只分为三大类,梁桥、拱桥和吊桥、斜拉索桥。梁桥一般建在跨度很大,水域较浅处,由桥柱和桥板组成,物体重量从桥板传向桥柱。简支板梁桥跨越能力最小,一般一跨在8-20m。连续梁桥是国内最大跨径在200m以下,国外已达240m。拱桥一般建在跨度较小的水域之上,桥身成拱形,一般都有几个桥洞,起到泄洪的功能,桥中间的重量传向桥两端,而两端的则传向中间。在竖向荷载作用下,两端支承处产生竖向反力和水平推力,正是水平推力大大减小了跨中弯矩,使跨越能力增大。理论推算,混凝土拱极限跨度在500m左右,钢拱可达1200m。亦正是这个推力,修建拱桥时需要良好的地质条件 ...

【技术特征摘要】
1.建筑施工中桥梁裂缝修补时的施工工艺,其特征在于,包括以下步骤:(1)按照设计要求的尺寸裁剪碳纤维布,施工前应对粘贴部位混凝土的表层含水率及所处环境温度进行测量,若混凝土表层含水率>4%或环境温度<5℃,则应采取措施,在达到要求后再进行施工;(2)去除被加固构件表面疏松部分,直至露出混凝土结构层,若有裂缝,应先行修补,然后用修补材料修复平整,并保证混凝土保护层厚度不小于15mm,粘贴部位的混凝土,若其表面坚实,也应出去浮浆层和油污等杂质,并打磨平整,直至露出集料新面,且平整度应达到5mm/m;构件转角处应打磨成圆弧状,圆弧半径...
