Guangzhou some stadium covers an area of an area to be 6.9 hectare, wait for composition by playground of training place, indoor swimming-pool, standard, football ground, it is earlier use water supply one of projects of plastic pipe, the lawn ground that standard playground follows a football ground in the center waters be defeated by conduit to was defeated by pipeline matching water to adopt U-PVC water supply with indoor swimming-pool plastic pipe.
The actuating pressure of equipment of indoor swimming-pool water supply is 0.25mpa, feed pipe road all uses U-PVC water supply plastic pipe, diameter is the biggest feed pipe DN200mm, bright set pipeline, adopt felt join way.
Lawn ground waters actuating pressure of water supply equipment is 0.8mpa, belong to water supply of discontinuity high pressure. Pipeline all uses U-PVC water supply plastic pipe, diameter is the biggest feed pipe DN150mm, lucainaming sets pump room inner tube, the pipeline outdoor buries the ground to lay, because limits of ground of playground ground benefit from is restricted, partial pipeline setting is inside catchment open drain, whole system all is adopted bear insert balata the circle is flexible join means.
Because be applied in plastic pipe inchoate technical to its master with construction method insufficient, the two place after complete are defeated by pipeline matching water trying when moving, appear different the slack phenomenon of degree, indoor swimming-pool pipeline is main and slack piece at present on the pipeline inside pump room, and the lawn of athletic field, football field waters be defeated by conduit slack basically go out at present on the pipeline outdoor. From theoretic those who see swimming-pool pipeline is slack can understand, and the lawn with water supply greater pressure waters the system is slack also should go out systematic pressure is at present highest place, already on pump room or the pipeline that close pump room is in, but actually slack the middle that points out to be far from pump room at present and end paragraph on pipeline. Try water repeatedly through undertaking to this two place field exploring, analysis follows, those who discover the problem is not to go out to provide material at present bear force follows quality to go up, went up to adopt the fixed way of similar metal service pipe to the fixed establishment of plastic pipe in construction however.
