When installing the covers, we should pay attention to the protection work,
so as to be able to effectively prevent the occurrence of manhole accidents. So,
how should we solve this problem? Here we come to introduce to avoid the manhole
accident, we should pay attention to several important aspects.
First, when installing the covers, the excavation of the excavation in the excavation of the wellhead reinforcement within the pavement structure, is strictly prohibited disturbed around the road surface structure. Dredging material should be isolated from the road piling up, and timely clearance.
Second, the wellhead cover inspection wells Masonry is completed, immediately install the temporary cast iron cover for cover protection. To prevent the construction of materials or debris into the well, to avoid personal injury.
Third, the concrete pouring concrete pouring should be in the well around the road pavement protective materials, to prevent the cement slurry pollution pavement. The use of covered water conservation, and set up measures to prevent the destruction of concrete structures or cast iron covers installed loose.
Fourth, the cast iron covers slope slope cast iron cover installation is complete, need to release the traffic, should be ahead of the road than the cast iron cover around the use of fine stone concrete or asphalt slope to ensure traffic safety.
Above Xiaobian for everyone to introduce is to avoid the manhole accident occurred, we installed, we should pay attention to several points, we must pay attention.
