When concreting concrete pouring, protective materials should be laid on the pavement around the wellhead to prevent the cement slurry from polluting the pavement, and to cover the maintenance of water and sprinkle, and to set up the enclosure measures to prevent the man-made destruction of the concrete structure or the loosening of the installation of the cast iron cover.
The brick masonry of the cast iron shaft cover should be determined in accordance with the size of the shaft cover designed by the design institute and the length * width, and the square circle (as in the case of actual construction), and the corresponding reference standard。 When laying well, we must pay attention to the inner diameter of the wellhead should be in line with the inner diameter of the well grate, and the well cover should be leveled with the road surface。 After the concrete or asphalt is cast, the cover should be cleaned in time so that the mortar or bitumen will be checked and the cover is poured into one in order to avoid the later opening。
When the cast iron cover plate is installed, it is necessary to use fine stone concrete or asphalt along the well cover around the road surface to ensure driving safety.
In order to keep the appearance of the cover, the surface pattern and the handwriting are clear, when the asphalt pavement is constructed, the thin iron cover is applied to cover the cover of the well cover or the waste oil, so as to prevent the asphalt oil from spraying on the cover of the well。 The water can be used to clean the surface of the well when the construction is finished。
