Description
Technical field
The utility model relates to the network of underground manhole, especially belongs to the leakproof inner bag in the network of underground manhole.
Background technology
Along with the development of urban construction, the construction of network of underground and very heavy with transformation task.For example soil pipe and these two kinds of network of underground of rain pipe in existing city, its manhole is to adopt concrete or brickwork construction to build to form, and be that gap connects between the borehole wall of manhole and pipeline, so these two kinds of structures all exists the defect of construction.
The concrete structure manhole: its inwall is subjected to the corrosion of rain sewage for a long time, causes the well damage in inner surface, and reinforcing steel bars exposed has shortened application life of manhole;
The manhole of brickwork construction: the cement mortar of well inner surface is subjected to the corrosion of rain sewage for a long time, and affected by ground shock load, causes the cement mortar skin breakage or comes off, and the rain sewage in manhole, to underground, pollutes underground by brick slit flow.
During lower than groundwater table, the waste water of underground pollution can flow in manhole when the water level in manhole.If pipe network is rain pipe: the discharge of wastewater of pollution, to rivers or ocean, causes rivers or marine pollution; , if pipe network is soil pipe: underground water can flow in manhole, sewage load and cost have been increased.Especially coastal cities, the seawater composition of underground water is larger, and the chlorion in seawater can affect the effect of sewerage treatment, even causes production accident.
Be that gap connects between the borehole wall of manhole and pipeline, the leakage problem ubiquity in gap, there is no so far effective way and solve.

For solving the problems of the technologies described above, the leakproof inner bag of a kind of network of underground manhole of the present utility model, comprise courage body, courage neck, connecting flange, seal, the courage body is square tube or drum, the bottom of courage body is provided with outer lug boss, be provided with through hole in outer lug boss, through hole is used for the insertion of underground pipeline, and underground pipeline is connected with courage body internal diameter; The courage neck is the bottleneck shape, and upper neck is by chamfered transition to lower neck, and the inside and outside collar of lower neck is corresponding with courage inside and outside collar size; Courage body and courage neck are connected into the leakproof inner bag by connecting flange, seal, securing member, and the leakproof inner bag is the doleiform shape, and the leakproof inner bag is placed in the network of underground manhole, with network of underground manhole inwall, link and with underground pipeline, are connected.
Be provided with stepped hole in the external boss of described courage, stepped hole is provided with sealing mat, and gland is placed on sealing mat.Gland links by securing member and courage body, and sealing mat is used for the sealing of through hole and underground pipeline.
Compared with prior art, its advantage and beneficial effect are the utility model:
1. adopt the leakproof inner-tube structure in the network of underground manhole, effectively prevented the leakage of network of underground manhole, be conducive to environmental protection, greatly improved the quality of Urban Buried Pipeline Network manhole;
2. the leakproof inner bag is convenient to the maintenance of network of underground manhole, and is time saving and energy saving, reduces costs, and increases work efficiency; The leakproof inner bag adopts anticorrosive, extends the application life of leakproof inner bag and network of underground manhole.

In figure: leakproof inner bag 10, courage body bottom 11, gland 12, sealing mat 13, courage body 14, courage neck 15, connecting flange 16, seal 17, outer lug boss 18, through hole 19, stepped hole 21;
At the bottom of the brick well 30 of concrete, concrete well 31, underground pipeline 32, brick walling 33, cement mortar 34, brick crib 35, coagulation earth mulch 36, concrete well face 37;
Leakproof inner bag 2 40, gland 2 42, sealing mat 2 43, courage body 2 44.
The specific embodiment
As shown in Figure 1, be the leakproof inner-tube structure schematic diagram of the utility model network of underground manhole.Leakproof inner bag 10 is the doleiform shape, and it comprises courage body 14, courage neck 15, connecting flange 16, seal 17.Courage neck 15 is the bottleneck shape, and upper neck is by chamfered transition to lower neck, and the inside and outside collar size of lower neck is corresponding with courage body 14 collar sizes; The shape of courage body 14 is square tube or drum, the bottom 11 of courage body.The bottom of courage body 14 is processed with outer lug boss 18, is processed with through hole 19 in outer lug boss 18, is used for inserting underground pipeline 32, and underground pipeline 32 is connected with the internal diameter of courage body 14; Courage body 14 is connected into leakproof inner bag 10 with courage neck 15 by connecting flange 16, bolt, seal 17, connecting flange 16 is placed on the internal diameter of courage body 14, courage neck 15, seal 17 is placed between courage body 14 and courage neck 15 end faces, guarantees both to connect sealing, with Leakage prevention.Courage body 14 is identical with courage neck 15 materials, all adopts plastics or glass-reinforced plastic material, and to prevent 10 corrosion of leakproof inner bag, this routine material is glass fiber reinforced plastic.The material of seal 17 is rubber.
Be processed with stepped hole 21 in outer lug boss 18, stepped hole 21 is used for dress and the sealing mat 13 that underground pipeline 32 seals mutually, fills gland 12 on sealing mat 13, and the material of sealing mat 13 is rubber.
Under base area, the specification of pipe network inspection well size is made different leakproof inner bags 10, and for example the manhole degree of depth is different, and the length on dark manhole courage body 14 tops is wanted spreading, and long joining section can use connecting flange 16, bolt, seal 17 to connect equally.
Leakproof inner bag 10 is put at the bottom of the concrete well of building in advance on 31, then built brick walling 33, brick crib 35, cement mortar 34 outside it, make cement mortar 34 solid with leakproof inner bag 10.During building, first from bottom, build brick walling 33, brick crib 35.The port of underground pipeline 32 is installed in the through hole 19 of courage body 14, dress sealing mat 13, gland 12 on stepped hole 21, gland 12 is fixing by bolt and courage body 14.Guarantee after assembling that underground pipeline 32 and the through hole 19 of courage body 14 seal.Then progressively build height outside leakproof inner bag 10, cement mortar 34 progressively joins admittedly with leakproof inner bag 10,, until build to concrete well face 37, covers finally coagulation earth mulch 36, forms the brick well 30 of concrete.
Adopt leakproof inner bag 10 can keep watertightness, can resist the leakage that the well inside and outside differential pressure produces, improve the quality of network of underground manhole.Leakproof inner bag 10 adopts anticorrosive, can increase the service life.
As shown in Figure 2, be the embodiment schematic diagram.The present embodiment is to the transformation of existing network of underground manhole, load onto leakproof inner bag 2 40 in existing network of underground manhole., because leakproof inner bag 10 can't put in existing concrete covers 36 lid hole,, so should first remove the epimere section of existing brick crib 35, brick walling 33, cement mortar 34, be equivalent to remove the External building (seeing Fig. 1) of courage neck 15 parts.Then put into leakproof inner bag 2 40 in well, after reconstruction, leakproof inner bag 2 40 is with the shape difference of leakproof inner bag 10, only processes through hole on the courage body 2 44 of leakproof inner bag 2 40 and without outer lug boss 18.Because underground pipeline 32 has installed, so sealing mat 2 43 is contained on the through hole of courage body 2 44, gland 2 42 is housed on sealing mat 2 43, and gland 2 42 is fixing by bolt and courage body 2 44, guarantees after assembling that underground pipeline 32 and the through hole of courage body 2 44 seal mutually.Then build in the outer part that will remove of leakproof inner bag 2 40.
