Detailed description of the invention
The utility model as Figure 1-5, comprises body 13(body and connects successively), one end of described body 13 is female end 131, and the other end is socket end 132; The outer wall of described female end 131 is connected with the outer steel loop 1 of bellmouth, inwall is connected with steel loop 4 in bellmouth, the outer steel loop 1 of described bellmouth stretches out the end face of described female end, and in the outer steel loop 1 of described bellmouth and bellmouth, the inner side of steel loop 4 is respectively equipped with inner groovy 14, fills out 10 for placing waterproof sealing;
The outer wall of described socket end 132 is connected with the outer steel loop 5 of socket, and inwall is connected with steel loop 8 in socket;
The internal diameter of the outer steel loop 1 of described bellmouth is greater than the external diameter of described socket end 132;
Be provided with madjack pipe 9 in described socket end 132, on described madjack pipe 9, welding is provided with madjack pipe waterproof sealing 12, the seepage between the madjack pipe preventing the play of madjack pipe from causing and body.
Be provided with cage of reinforcement in described body 13, the outer steel loop 1 of described bellmouth is connected described cage of reinforcement with steel loop in bellmouth 4 by connecting reinforcement; The outer steel loop 5 of described socket is connected described cage of reinforcement with steel loop in inserted block 8 by connecting reinforcement.Namely the outer steel loop 1 of bellmouth is connected with the cage of reinforcement in tube coupling (i.e. body 13) by connecting reinforcement 1; In bellmouth, steel loop 4 is connected with the cage of reinforcement in tube coupling by connecting reinforcement 23; The outer steel loop 5 of socket is connected with the cage of reinforcement in tube coupling by connecting reinforcement 36; In socket, steel loop 8 is connected with the cage of reinforcement in tube coupling by connecting reinforcement 47.
Also comprise water expanding sealing strips 11, described water expanding sealing strips is connected between the female end end face of adjacent tubes and socket end end face.
Described body 13 is rounded or square, the selection of constructability.
The utility model has introduced a kind of brand-new theory and the structure of the design of Urban Underground pipe gallery and construction, can design according to needing in Urban Underground pipe gallery the requirement of the various pipelines arranged, and adopt batch production to manufacture pipe gallery concrete tube coupling, and then be transported to Urban Underground pipe gallery job site and construct." behind Gou Xian road " mode of traditional excavation groove mounting pipe corridor superimposed fill again can being adopted during construction, also can adopt the advanced technology following structure driving jacking construction when not destroying ground, keep original road surface or on the ground appurtenance be not destroyed.
When underground pipe gallery is installed, in bellmouth, in steel loop inner groovy, waterproof sealing filler 10 is installed; The bellmouth of adjacent two tube couplings and and socket between water Expansion sealing adhesive tape is installed; After two adjacent tube coupling installations, by madjack pipe 9 indentation sealing waterproof slurries, water-tight slurries are full of the space between the soil of gap between the bellmouth of adjacent two tube couplings and socket and tube coupling joint and periphery, make piping lane reach sealing antiseepage after water-tight grout cures.If when adopting ditching construction technology, first shutoff madjack pipe, then can carry out mud jacking sealing outside piping lane, also can carry out mud jacking sealing from inside.
After whole construction completes, waterproof sealing filler is installed in adjacent tube coupling to concordant with piping lane inwall between steel loop, water Expansion sealing adhesive tape.
Underground pipe gallery of the present utility model square culvert pipe joint manufactures in factory, and what reinforcing cage was contained in side rolls employing mould, rolls that precision is high, production efficiency is high, cost of production is low; The pouring concrete of Fang Han adopts metal die to produce, and template precision is high, die life long (can reach tens thousand of times), mounting or dismounting mould speed are fast, efficiency increases substantially.Compared with in-site pouring technique, the batch production manufacture of Fang Han, the mill speed of reinforcing cage improves more than 4 times than site operation, and mould assembling and dissembling speed improves more than 10 times, production efficiency improves more than 3 times, and the cost of underground pipe gallery is only about 60% of cast-in-site technique.
Fang Hanguan saves after factory manufactured, transports to underground pipe gallery erecting bed, on-the-spotly only needs square culvert pipe to save to be lifted into section by section in the ditch dug to put on right position, then backfill compacting, then carries out the antiseepage of mud jacking sealing from inside.The in-site installation engineering time of underground pipe gallery, site operation expense reduced about 40% than cast-in-site process shortens more than 2/3rds.
