Assembly type large-expansion-amount polyurethane expansion joint device and construction method thereof
The invention discloses an assembly type large-expansion-amount polyurethane expansion joint device and a construction method thereof. The assembly type large-expansion-amount polyurethane expansion joint device comprises a prefabricated polyurethane expansion joint, polyurethane concrete, a reserved gap, a joint crossing steel plate, bridge concrete, an adhesive and an expansion joint groove area. The method comprises the steps that the expansion joint groove area is firstly cleaned; then, polyurethane concrete is prepared; then, a layer of polyurethane concrete is laid at the bottom of the expansion joint; the two faces of the joint-crossing steel plate are coated with a release agent, and then the joint-crossing steel plate is placed on polyurethane concrete; the prefabricated polyurethane elastomer expansion joint is placed on the joint crossing steel plate; then, the side face of a groove area of the expansion joint and the trapezoidal slope face of the prefabricated polyurethane elastomer expansion joint are coated with an adhesive, and the next step of operation can be carried out after 1 h; and finally, the notch is filled and leveled up with polyurethane concrete. According to the method, the restriction of working conditions on construction requirements is reduced, the time for opening traffic is greatly shortened, and the pavement layer connected with the expansion joint device is protected.
本发明公开了一种装配式大伸缩量聚氨酯伸缩缝装置及其施工方法，包括预制聚氨酯伸缩缝、聚氨酯混泥土、预留空隙、跨缝钢板、桥梁混泥土、粘合剂、伸缩缝槽区，先清理伸缩缝槽区；再配置聚氨酯混凝土；然后在伸缩缝底部铺设一层聚氨酯混凝土；将跨缝钢板两面涂刷脱模剂，然后放置于聚氨酯混凝土上面；将预制聚氨酯弹性体伸缩缝放置在跨缝钢板的上面；接着在伸缩缝的槽区侧面以及预制聚氨酯弹性体伸缩缝的梯形坡面涂刷粘合剂，1h后即可进行下一步操作；最后使用聚氨酯混凝土将缺口填平。本发明减少了工况条件对施工要求的制约，大幅减少开放交通的时间，保护与伸缩缝装置相连的铺装层。
