State Puncture Tube top and spheroidal graphite cast-iron lid is installed, if bolt stem is provided with the spheroidal graphite cast-iron tops, and the spheroidal graphite is cast
Cushion rubber ring is provided with iron covering, the spheroidal graphite cast-iron body most external is provided with outside anti-erosion layer, the outside anti-erosion layer
Lower section is provided with cement lining layer, and the spheroidal graphite cast-iron body penetralia is provided with corrosion-resistant coating, the Puncture Tube and connecting tube
Connection, the connecting tube bottom is connected with acid-base modifier storage ball, and permeability hole is provided with the acid-base modifier storage ball.
Preferably, the liner cement layer is the inside packed layer of the spheroidal graphite cast-iron body.
Preferably, the thickness of the liner cement layer is 3-10mm.
Preferably, the permeability hole is circular web frame, and a diameter of 2-3mm.
Preferably, it is to be flexibly connected between the spheroidal graphite cast-iron lid and the Puncture Tube.
The beneficial effects of the invention are as follows：Liner cement layer can protect water quality, reduce the loss of flood peak, improve T-shaped spheroidal graphite casting
The service life of iron pipe, corrosion-resistant coating can improve the corrosion resistance to the soda acid composition in sewage, outside anti-erosion layer energy
Enough protection ductile iron pipes are embedded in suffered erosion under soil for a long time, further improve the corrosion resistance of T-shaped ductile iron pipe,
Acid-base modifier is stored in acid-base modifier storage ball, for neutralizing the soda acid composition in sewage, is reduced to ductile iron pipe
Internal corrosion, the present invention has been effectively ensured the service life of ductile iron pipe, while being provided conveniently to follow-up sewage disposal.
