Bridge expansion joint construction method
The invention relates to a bridge expansion joint construction method which comprises the following steps that S1, an expansion joint device is manufactured, and the expansion joint device is obtained by welding strip-shaped steel bars; S2, after pre-embedded ribs in the longitudinal direction and the transverse direction of the expansion joint are pre-embedded in the top end of the bridge abutment, asphalt is laid on the basic road surface, and the asphalt is ground and laid compactly; S3, a cutting device is used for cutting joints in the positions of the embedded ribs, an air pick is used for grooving, asphalt concrete and loose cement concrete in grooves are chiseled away, and a powerful blower or a high-pressure water gun is used for removing floating dust and impurities; S4, the expansion joint device is placed in the groove obtained in the step S3, the embedded ribs and the expansion joint device are welded, the inner wall of the expansion joint device is completely coated with asphalt structural adhesive, and then the steel cover plate is installed in the expansion joint device; and S5, the outer surface of the steel cover plate is coated with a layer of asphalt structural adhesive, a foam plate is installed in the expansion joint device, and finally concrete pouring is performed on the expansion joint device to obtain the bridge expansion joint.
本发明涉及一种桥梁伸缩缝施工方法，包括如下步骤：S1、制作伸缩缝装置，通过条形钢筋焊接得到伸缩缝装置；S2、在桥台顶端预埋伸缩缝的纵向与横向上的预埋筋后，在基本路面铺设沥青并碾压铺实；S3、利用切割装置在预埋的预埋筋位置进行切缝，用风镐开槽，对槽内的沥青砼、松动的水泥砼进行凿除，并用强力吹风机或高压水枪清除浮尘和杂物；S4、将伸缩缝装置放在步骤S3中得到的槽内，并将预埋筋与伸缩缝装置进行焊接，用沥青结构胶将伸缩缝装置内壁全部涂覆后将钢盖板安装于伸缩缝装置内；S5、在钢盖板外表面上涂刷一层沥青结构胶，并在伸缩缝装置内安装泡沫板，最后对伸缩缝装置进行过混凝土浇筑得到桥梁伸缩缝。
