Summary of the invention
The purpose of the utility model provides a kind of structure that is tightly connected that can adapt to the plastic inspection well bellmouth of variety classes plastic drain-pipe.
The technical scheme of the utility model is: a kind of structure that is tightly connected of plastic inspection well bellmouth comprises manhole well seat 1, bellmouth 2, airtight and watertight padding 3, sealing ring 4, hot melt band 5, plastic pipe 6.Bellmouth 2 is fixedly connected on the manhole well seat 1.Plastic pipe 6 inserts in the bellmouth 2, is filled with airtight and watertight padding 3 in the slit between the two.Sealing ring 4 is equipped with on airtight and watertight padding 3 tops, hot melt band 5 cover on the sealing ring 4 and seal up bellmouth 2 and plastic pipe 6 between the slit.
Slit between said bellmouth 2 and the plastic pipe 6 is 5～15mm.
Said bellmouth 2 is interior wimble structure, and the bottom of plastic pipe 6 contacts with the bellmouth 2 interior conical surfaces.
Said bellmouth 2 adopts the mode of socket joint sweat soldering to be connected with manhole well seat 1.
Adopt bellmouth 2 conical surfaces during the utility model sealing, airtight and watertight padding 3, sealing ring 4 carries out the level Four sealing with hot melt band 5.The linear sealing of plastic pipe 6 end faces and bellmouth 2 conical surfaces is a primary seal, and airtight and watertight padding 3 is a secondary seal, and sealing ring 4 is three grades of sealings, and hot melt band 5 is the level Four sealing.Airtight and watertight padding 3 is the flexible sealing packing material, comprises corrosion resistant asbestos cord, pitch flax silk, polystyrene board, Vestolit plate and viscosity flow property rheid material etc.
Bellmouth 2 adopts the socket joint sweat soldering with manhole well seat 1; Airtight and watertight padding 3 places between bellmouth 2 and the plastic pipe 6; Sealing ring 4 is used for airtight and watertight padding 3 fillings and is placed on the shutoff sealing between bellmouth 2 and the plastic pipe 6; Hot melt band 5 and bellmouth 2 and plastic pipe 6 sweat solderings with sealing between further assurance bellmouth 2 and the plastic pipe 6, improve bonding strength and reliability between bellmouth 2 and the plastic pipe 6 simultaneously.
The beneficial effect of the utility model is:
(1) bellmouth and manhole well seat adopt the socket joint sweat soldering, and connection flexibility is good, and bonding strength is high, and good reliability, sealing are prone to guarantee;
(2) bell and spigot of bellmouth is interior wimble structure, and socket joint property is good, and socket joint is convenient, and compliance is strong, can satisfy the different types of plastic pipe of same specification and link to each other;
(3) flexible materials such as corrosion resistant asbestos cord are adopted in airtight and watertight padding, and filling property is good, plays certain sealing function simultaneously;
(4) select the sealing ring of different section diameter according to the socket joint gap of variety classes plastic pipe, guarantee sealing effectiveness;
(5) hot melt band welding has not only guaranteed sealing, and has greatly improved the intensity that socket joint connects;
(6) plastic pipe be connected with bellmouth flexible good.
