With the continuous development of skills, manhole covers have been rapidly developed as common materials for municipal administration and construction. The resin composite manhole covers produced by new composite materials have become newcomers to manhole covers. In order to ensure the normal use of composite manhole covers, the quality of the device should be attached great importance to and the scale must be accurate The device is consolidated, open and convenient, and the surface is clean and beautiful. According to the skill standards of the composite data manhole cover, the following device details are specially formulated:
1. Before installation, the foundation of the manhole cover should be regularly consolidated, and the inner diameter and length and width should be determined according to the size of the manhole cover.
2. When the composite manhole cover is installed on the cement pavement, pay attention to the use of concrete pouring on the masonry of the wellhead, and also establish a concrete maintenance circle on the periphery for about 10 days.
3. In the composite manhole cover of the asphalt pavement device, attention should be paid to prevent the construction machinery from directly rolling the manhole cover and the well seat to avoid damage.
Fourth, in order to maintain the beauty of the manhole cover and the clear handwriting and pattern, pay attention not to stain the manhole cover when pouring asphalt and cement on the road surface.
5. After the well is cast or asphalt is laid in concrete, the well cover should be opened and cleaned in time to prevent mortar or asphalt from pouring the inspection well cover and the seat into one body, so as not to affect the openness in the future. --- Manhole cover wholesale
