Inwall inclination of the present utility model is 3 °, give the activity space that joint area is certain, the destruction because of unfavorable factor butt joints such as soil uneven settlement, earthquakes can be alleviated, ensure the Security of joint, bellmouth inner cavity size has done suitable increasing process under the prerequisite guaranteeing sealing, to adapt to socket ovalizing deflection as far as possible, ensure easy for installation, bellmouth and pipe shaft position excessively have one by circular arc and the level and smooth combination of an external arc, total quality is little, and cost reduces.And when mounted, soft section is installed in square groove and V-type groove, form fold line seal, relative to traditional line seal, good sealing effect.And structure is simple, and Security is good.
The each several part of described bellmouth and socket is of a size of: D1=Ф 1811mm, D2=Ф 1740 mm, D3=Ф 1674 mm, D5=Ф 1720 mm, D6=Ф 1680 mm, D7=Ф 1752 mm, D8=Ф 1781 mm, rA=100 mm, rB=215 mm, C=5 mm, D=15 mm, F=5 mm, DE=1668 mm.
The each several part of described seal ring is of a size of: h1=86 mm, h2=30 mm, h3=24 mm, h4=64 mm, D9=Ф 1770 mm, D10=Ф 45 mm, D11=Ф 1790 mm.
Further, the material of described bellmouth is spheroidal graphite cast iron, structural stability.
The utility model compared with prior art has following beneficial effect: inwall inclination of the present utility model is 3 °, give the activity space that joint area is certain, the destruction because of unfavorable factor butt joints such as soil uneven settlement, earthquakes can be alleviated, ensure the Security of joint as far as possible, bellmouth inner cavity size has done suitable increasing process under the prerequisite guaranteeing sealing, to adapt to socket ovalizing deflection, ensure easy for installation, bellmouth and pipe shaft position excessively have one by circular arc and the level and smooth combination of an external arc, total quality is little, and cost reduces.And when mounted, soft section is installed in square groove and V-type groove, form fold line seal, relative to traditional line seal, good sealing effect.And structure is simple, and Security is good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail.
