Reduce the safety failure of wellhead

Nodular cast iron manhole covers safety, has become a more attention to the subject, however, road construction, the weak link is the cap, pipeline crossing, once the processing is bad, can cause personal injury to the comings and goings of pedestrians, this is not a hidden trouble, we can see it on the news is very much also, so we should how to reduce this problem? How to use it more safely and safely, how to construct it correctly, with a brief introduction from botou tianlong casting.

1.within the scope of the invisible wellhead reinforced pavement structure of foundation pit excavation, it is strictly prohibited to disturbance nodular cast iron manhole covers around the wellhead of pavement structure, dig out the material should be from the pavement piled up, and cleaned up and transported away without delay.

2. the concrete pouring of concrete should be paved around the wellhead protection materials, prevent cement road surface pollution, using cover sprinkler maintenance, and containment measures, prevent nodular cast iron manhole cover caused by man-made destroy concrete structures or installation is loose.

3. Once the well is completed, the temporary nodular cast iron manhole cover shall be installed immediately to cover protection, preventing construction materials or debris from falling into the well to avoid personal injury.

4.The installation of ductile iron manhole covers should be completed and the vehicles should be free. The use of concrete or asphalt shall ensure safe driving.

Botou tianlong casting iron manhole cover, the quality of the material, through the strict request of hole design circle and the coverage degree to achieve the quality is good, in order to guard against theft, and shock absorption, the purpose of this requirement when the design not only need to accurately calculate some data, also need to design in practical characteristics, in order to ensure the botou tianlong casting use the product, can be more at ease.
