Lanzhou plastic manholes manufacturers preferred Science and Technology of Gansu Henghua

Lanzhou, Gansu plastic manholes manufacturers preferred Heng Hua Science and Technology of plastic injection molded plastic disposable manholes manholes performance characteristics does not leak tight connection between the pipe and the well plastic manhole connection flexible connection flexibility tightness valid prevent water leakage to avoid secondary contamination of groundwater and environmental safety and well-soil pipe-soil settlement movement even solved the problem of uneven settlement of traditional brick well with plastic pipe connection to effectively prevent ground subsidence resulting light weight easy handling and installation of plastic inspection Karuizawa weight at construction sites and other places of easy removal and installation of wells to solve the traditional brick and reinforced concrete manhole bulky and inconvenient to install internal corrosion problems in order to solve the construction and installation of plastic manholes speed acid and many other media are not smooth easy to stay sewage manholes and plastic raw materials containing polyvinyl chloride having a corrosive effect acid, etc. so as to prolong the life of the pipeline through clear plastic manhole easy to maintain a small amount of plastic manholes and easy maintenance without the need to clean up crushed stone bricks, etc. debris can clog sewer pipes to prevent serious duct obstruction problem can change the traditional brick and reinforced concrete manholes wells footprint is small and beautiful plastic manholes drainage pipes tighter cost savings in the narrow space of excavation has more advantages without affecting the surrounding environment beautiful and practical issues of economic performance good performance plastic manholes land and water-saving environmental protection and energy saving materials recyclable plastic manholes in line with the sustainable development of countries in the policy of disposable plastic injection molding plastic manholes Manhole then family pipe installation methods start with initial installation gradually upstream section to the downstream branch tube wells tube wells dry tube extends to the seat tube wells installed in the order header and piping construction methods and construction methods should be connected to the same type of pipe joints consistent well base installation immediately catchy wellbore placement should be temporarily plugging the rubber seals should be placed well when plastic seat and bellows connected to the first trough when the entire drainage system implemented in phases of construction inspection and acceptance of the connection pipe segments next Interface should not be used as a temporary closure according to the depth of manhole pipe to be cut on the finished borehole cut should be smooth and perpendicular to the axis of the tube when the hammer beating wellbore plug should be tightened using special tools backfill should contain pipes and drain lines other tests well after acceptance shall be backfilled backfilling mud mixed with garbage and permafrost, etc. not lumps of stone bricks and other objects backfill the edges of each layer with application of wood and other lightweight tools consistent with its density and pipeline backfill time injection molded plastic manholes Advantages Description construction conditions without any influence of climate and environment without having to go down to clear the good safety workers avoid gas poisoning material properties of good acid corrosion Manhole raw materials containing polyvinyl chloride which itself corrosion resistance and good sealing None penetration leak connections with flexible plastic pipe connection unequal settlement manholes having flexibility and excellent resistance to scratching ability to bend and move easily in case of paved roads interludes settlement dislocation is not easily broken sewage capacity seismic resistance of reinforced plastic manhole concrete manhole times convenient plastic manholes maintain clean up debris without plastic manholes discharge pipe is more compact and more cost-saving advantages of the excavation in a small space
