Quick replacement method for expansion joint concrete
The invention relates to the technical field of expansion joints, discloses a rapid replacement method of expansion joint concrete, and aims to solve the problems that when an expansion joint device is replaced, traffic needs to be closed for a long time, and traffic is affected. Secondly, the working procedures on the construction site are more, and the labor cost and the required manufacturing cost are high; in addition, the replacement time of expansion joint concrete is long, the efficiency is low, rapid replacement is difficult to achieve, and the method comprises the following steps of dismantling and cleaning, pouring and airing, sealing and pressing, heating and mixing and layered paving. The expansion joint device is manufactured into a whole according to any length in a factory, compared with a butt-welding joint device on-site welding fixing and transition section concrete structure pouring technology, on-site construction steps and construction time are reduced, the needed cost is reduced, in addition, in the replacement operation process, a road is controlled through semi-closed control, and the replacement efficiency is improved. And moreover, the construction time is short, and the traffic is unobstructed while being repaired, so that the traffic pressure is reduced.
本发明涉及伸缩缝技术领域，公开了一种伸缩缝混凝土的快速更换方法，为解决的问题是：伸缩缝装置的更换，需长时间封闭交通，影响交通；其次施工现场的工序较多，人力成本和所需造价颇高；此外对于伸缩缝混凝土的更换所需时间久效率低，难以实现快速更换，包括以下步骤：拆除清理，浇筑晾干，密封压紧，加热拌和，分层摊铺。本发明中通过在工厂内对伸缩缝装置按任意长度制作成一体，相较于对焊接缝装置在现场焊接固定和浇注过渡段混凝土结构工艺，减少了现场施工步骤和施工时间，降低了所需成本，此外在进行更换作业过程中，通过半封闭管制控制道路，无需全幅封闭交通，且施工时间短即修即通，减少了交通压力。
