Abstract
The utility model discloses a cold region tunnel heat preservation blind pipe, including the blind pipe, the surface of blind pipe has cup jointed interior pipe box, outer pipe box has been cup jointed to the outside of interior pipe box, clearance intussuseption between interior pipe box and the outer pipe box is filled with the lightweight polyurethane filling layer, the outer tube is sheathe in and has been seted up the inlet opening, the one end that outer pipe box was kept away from to the inlet opening runs through lightweight polyurethane filling layer, interior pipe box and blind pipe in proper order. The utility model discloses double -deck heat preservation hoop blind pipe, simple structure, convenient to use can not have the dead point to the blind pipe and keeps warm, and it is effectual to keep warm to do not influence the function of drainage, prevented that the blind pipe from freezing, has played better protection to tunnel engineering.
Description
Technical field
This utility model is related to annular blind pipe technical field, and specially a kind of tunnel in cold area is incubated blind pipe.
Background technology
Ring blind pipe is inserted into the tube having holes between country rock and first, is that the infiltration in just propping up guides to the longitudinal direction of bottom
Blind pipe, then to central ditch until discharging from dark hole, be the antifreeze important component part avoiding hydrops frost heave freeze injury of tunnel water proofing.
Although present blind pipe has warming plate to be thermally shielded insulation by tunnel side, it is located against the one of a just country rock
Side but cannot be effectively incubated, and may result in blind pipe in high and cold serious area and freeze, cause hydrops cannot flow out, not only
Have impact on the waterproof thermal-insulated effect in tunnel, also threaten the safety of whole Tunnel Engineering.
Utility model content
The purpose of this utility model is to provide a kind of tunnel in cold area insulation blind pipe, to solve to propose in above-mentioned background technology
Problem.
For achieving the above object, this utility model provides following technical scheme: a kind of tunnel in cold area is incubated blind pipe, including blind
Pipe, the outer surface of described blind pipe is socketed with inner tube set, and the outside of said inner tube set is socketed with outer tube sleeve, said inner tube set and outer tube
Be filled with light polyurethane packed layer in gap between set, described outer tube sleeve offer inlet opening, described inlet opening away from
One end of outer tube sleeve sequentially passes through light polyurethane packed layer, inner tube set and blind pipe.
Preferably, the gap between described outer tube sleeve and inner tube set is to connect shape structure.
Preferably, the quantity of described inlet opening is eight, and eight inlet openings are equidistant to be opened in outer tube sleeve.
Preferably, described outer tube sleeve is loop configuration.
Compared with prior art, the beneficial effects of the utility model are:
(1), this utility model double-layer heat insulation ring blind pipe, structure is simple, easy to use, and blind pipe no dead point can be incubated,
High insulating effect, and do not affect the function of draining it is therefore prevented that blind pipe freezes, Tunnel Engineering is served with more preferable protection.
(2), this utility model double-layer heat insulation ring blind pipe, by outer tube sleeve, inner tube set and light polyurethane packed layer
Use cooperatively, the gap Nei Wu dead angle light filling polyurethane between inner tube set and outer tube sleeve can be made, blind pipe is served more
Good heat insulation effect, it is to avoid blind pipe heat insulation effect is bad lead to freeze cannot draining situation.
Brief description
Fig. 1 is this utility model structural representation；
Fig. 2 is section of structure of the present utility model.
In figure: 1 blind pipe, 2 inner tube sets, 3 outer tube sleeve, 4 light polyurethane packed layers, 5 inlet openings.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-2, this utility model provides a kind of technical scheme: a kind of tunnel in cold area is incubated blind pipe, including blind pipe
1, the outer surface of blind pipe 1 is socketed with inner tube set 2, and the outside of inner tube set 2 is socketed with outer tube sleeve 3, and outer tube sleeve 3 is loop configuration, leads to
Cross using cooperatively of outer tube sleeve 3 and inner tube set 2, enable insulation material preferably docile on the surface of blind pipe 1, to blind pipe 1
To more preferable heat insulation effect, the gap between outer tube sleeve 3 and inner tube set 2 is to connect shape structure, between inner tube set 2 and outer tube sleeve 3
Gap in be filled with light polyurethane packed layer 4, outer tube sleeve 3 offers inlet opening 5, by outer tube sleeve 3, inner tube set 2 and
Using cooperatively of light polyurethane packed layer 4, can make the gap Nei Wu dead angle light filling between inner tube set 2 and outer tube sleeve 3
Polyurethane, serves more preferable heat insulation effect to blind pipe 1, it is to avoid blind pipe 1 heat insulation effect is bad, and lead to freeze cannot draining
Situation, the quantity of inlet opening 5 is eight, and eight inlet openings 5 are equidistant to be opened in outer tube sleeve 3, and inlet opening 5 is away from outer tube sleeve 3
One end sequentially pass through light polyurethane packed layer 4, inner tube set 2 and blind pipe 1, structure is simple, easy to use, can to blind pipe 1 no
Dead point is incubated, high insulating effect, and does not affect the function of draining it is therefore prevented that blind pipe 1 freezes, and Tunnel Engineering is served more preferably
Protection.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with multiple changes in the case of without departing from principle of the present utility model and spirit, repair
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
