As a traditional sewer manhole cover, the cement manhole cover has a long history of use. The cement manhole cover of Beijing Zhurong Cement Products Co., Ltd. is reasonable in design, light in weight, safe and reliable, and avoids the theft of traditional cast iron wells. Xushui cement manhole cover will not sink. Special attention should be paid to the surrounding ground during installation. The connection is completed so as not to cause color differences or cracks around the sink or manhole cover due to different construction processes, which greatly affects the aesthetics and usability of the highway. The concrete pouring module can be installed instead of the traditional clay bricklaying method. In order to reduce wellhead pressure, the coverage factor of steel fabric that can also be used for trapezoidal sections is fixed.
The masonry of Xushui cement manhole cover shall be determined in accordance with the designed manhole cover's inner diameter or length * width and squareness. At the same time, it can also be performed with reference to standards. When building a well, we must pay attention to the inner diameter of the wellhead and the inner diameter of the manhole cover. The installed manhole cover should be level with the road surface. In order to keep the appearance of the cover beautiful, and the surface pattern and writing of the cover clear, the thin steel sheet should be used to cover the cover of the manhole cover or waste engine oil during the construction of asphalt pavement to prevent asphalt oil from spraying on the manhole cover. During pavement construction, cover the manhole cover with a plastic film to prevent the cement mortar from contaminating the surface of the manhole cover and damaging the surface patterns and handwriting. You can also use water to clean the surface of the manhole cover when construction is completed that day.
