In recent years, with the advancement of urbanization, urban transportation has developed more rapidly. The maintenance of municipal engineering facilities has created good conditions for the general public to travel, and also provided a strong guarantee for large-scale activities such as the creation and re inspection of national civilized cities. In order to continuously improve our maintenance quality and actively create a municipal maintenance brand, we embody "precision" in the construction process and "delicacy" in the maintenance management process.
During the construction operation, for the maintenance of asphalt road, the branch company requires not only to dig out the base and asphalt within the damaged range and clean the base, but also that the foundation must be straight and smooth after excavation, and the pit wall must be free of concave and convex. In the maintenance of asphalt surface course, milling should not only ensure that the bottom layer is smooth and the edge is neat and vertical, but also add a milling knife in the width direction to avoid transverse staggered teeth and unsmooth edge line. After the asphalt is rolled for the first time, a special person must be assigned to check the joints, and a three meter straight edge must be used to check the smoothness of the pavement. For repeated problems such as hugging and rutting, anti rutting agent should be added to the middle and lower layers of asphalt, and semi flexible anti rutting pavement should be used for stubborn diseases of BRT lane. For the pavement joint, it is required that the pavement within 20 cm on both sides of the crack must be cleaned before the joint is pasted, and the joint surface must be flat without protrusion and bubble. For sporadic repair of pavement slab and side stone, we prepare and reserve the required varieties, specifications, sizes and surface treatment methods one by one, so as to ensure that the replacement materials are consistent with the original pavement materials, and improve the timeliness of maintenance; when dismantling, try not to damage the surrounding panels; when mixing mortar or concrete on site, do a good job of protection to avoid secondary pollution to the facilities; when laying, do a good job of maintenance It is required that the old and new materials should be connected smoothly, and the blocks around the inspection well or connected with the structure should be cut and supplemented to ensure the flatness and aesthetics. When replacing the inspection well, the edge shall be vertical without looseness after the base course is broken. Before the installation of the well frame, the bent embedded reinforcement must be restored, and the connection between the well frame, well cover and the road surface shall be strictly controlled.
In the management process of maintenance work, the branch company subdivides the personnel functions, so that the posts and tasks are assigned to each person, and each work is carried out efficiently and coordinately at all levels and links. By refining the management process, the work quality and efficiency are improved. The fine management of municipal maintenance not only improves the quality of maintenance work, but also effectively improves the appearance of the city.
