In fact, the manhole cover is no stranger to us, now covers species is also divided into many kinds: inorganic glass steel manhole cover, manhole covers, magnesite cement and iron manhole cover etc.. Our company is Shandong covers manufacturer, we have high quality products and high-quality staff, we will say that covers the installation details:
1, in order to maintain the beautiful appearance, covers the surface pattern and handwriting clear, the application of thin iron cover on the well cover or with waste oil brush cover in asphalt pavement construction, to prevent the asphalt oil direct injection on the well cover. In the cement pavement construction, application of plastic cover, to prevent contamination of the surface damage of cement slurry, the surface pattern and writing. Also available on the day of the construction end covers the surface of clean water.
2, concrete manhole cover casting or asphalt, should be timely covers open cleaning, avoid mortar or bitumen the manhole cover and a well seat poured into one, so as not to affect the day after opening.
3, the cover of brick masonry shall ensure that its diameter or length * width, radius according to the design institute covers the size (such as the sample, the best construction) can also refer to the implementation of the relevant standards.
4, on the road installed well base, concrete casting thickness of 20cm beam with C25 wells in smooth brick masonry, must maintain a well seat four indeed, overall smooth, not loose, and cast concrete protection ring width not less than 40cm in the outer cover, and reinforcement, maintenance period in 10 these days. The installation covers in asphalt pavement, we must pay attention to avoid the construction machinery to direct rolling shaft, on the road of integral casting, should be reserved for slightly larger than the shaft hole in the asphalt pavement, placed in the shop after (the concrete pavement should be two stones puwan after installation, ensure the grinding shaft installation) in order to prolong the service life of quality.
