The utility model is suitable for an in rich irrigated land section railway tunnel engineerings such as fault, karst growth, can prevent effectively that the too big ballastless track of causing of tunnel internal cause basement water pressure from arching up, ensured the safety operation of railway, the utility model has the characteristics of the construction is simple, the investment is little etc, application prospect is wide, and the construction operation is very simple, and engineering cost is extremely low.
Description
Technical field
The utility model belongs to a kind of tunnel inspection shaft and in particular to a kind of tunnel inspection with sluicing anti-floating function
Well.
Background technology
At present, China has been that Tunnel Engineering is largest in the world, quantity is most, geological conditions and version are the most multiple
Country miscellaneous, that technology of building is with the fastest developing speed.For railway tunnel, mostly using setting center in inverted arch packed layer
, as the drainage pattern of main drainage channel, center inspection shaft at the setting one that simultaneously keeps at a certain distance away, so that desilting, white-out for water pipe
Central water tube, meets the requirement of tunnel drainage system " can safeguard ".In addition, with the continuous development of high-speed railway, for meeting row
Overall height speed service requirement, generally starts in high ferro tunnel to lay non-fragment orbit.Although no tiny fragments of stone, coal, etc. rail compared with traditional Ballast track
Road can reduce maintenance, reduces dust, beautifies the environment, but the stability requirement to tunnel bottom structure is also higher.
However, in the last few years, the railway tunnel of operation, in water abundant ground such as tomography, karsts developing area, because hydraulic pressure is high, caused
The phenomenon of non-fragment orbit arch occurs repeatedly；Further, since the problems such as constructing tunnel technique, construction quality, leading to tunnel inverted arch
Situations such as bottom leakiness, inverted arch filling layering perform and inverted arch construction joint waterproof effect is undesirable is more universal, if tunnel
Road periphery underground water is developed, the water yield is enriched, and the weak location of these guarded drainage will produce ponding, under hydraulic pressure effect, causes
The protuberance of track plates, causes extreme influence to safety of railway operation.
Content of the invention
The utility model is to solve the problems, such as that prior art proposes, and its objective is to provide one kind to have sluicing anti-floating
The tunnel inspection shaft of function.
The technical solution of the utility model is：A kind of tunnel inspection shaft with sluicing anti-floating function, including inverted arch filling
Layer, tunnel inverted arch and be arranged on central drainage pipe in inverted arch packed layer, form inspection shaft in described inverted arch packed layer, described
Check well depth crossing-river tunnel inverted arch, reserve spilled water hole in the inspection shaft base plate of inspection shaft, in described spilled water hole, be inserted with overflow pipe,
Described inspection shaft side wall is connected with central drainage pipe.
It is provided with granular cushion, between described inspection shaft base plate, granular cushion below described inspection shaft base plate
It is provided with loaded filter.
Described loaded filter is geotextiles.
Described spilling water pipe outer wall is provided with, with the contact site of spilled water hole inwall, the rubber ring sealing.
Described overflow pipe is fixed with inspection shaft side wall phase.
Described overflow pipe pipe is risen in drainpipe.
Form pin nest in the wall of described inspection shaft side, and be provided with reinforcing bar cat ladder.
Described inspection shaft openend is provided with cover plate.
The utility model, be applied to the water abundant ground railway tunnel work such as tomography, karsts developing area, can effectively prevent tunnel
Road internal cause sole presses through and causes greatly non-fragment orbit to arch up, and has ensured the safe operation of railway, and the utility model has construction letter
The features such as single, investment is little, has a extensive future, constructing operation very simple, and construction costs is extremely low.

Specific embodiment
Hereinafter, with embodiment, the utility model is described in detail referring to the drawings：
As shown in Fig. 1 ~ 5, a kind of tunnel inspection shaft with sluicing anti-floating function, including inverted arch packed layer 6, tunnel inverted arch
7 and be arranged on central drainage pipe 8 in inverted arch packed layer 6, form inspection shaft 5, described inspection shaft in described inverted arch packed layer 6
5 depth crossing-river tunnel inverted arch 7, that is, inspection shaft base plate 2 be arranged at below tunnel inverted arch 7 bottom surface, the inspection shaft base plate 2 of inspection shaft 5
Interior reserved spilled water hole 1, is inserted with overflow pipe 12 in described spilled water hole 1, described inspection shaft 5 side wall is connected with central drainage pipe 8.
Spilled water hole 1 in inspection shaft base plate 2 and overflow pipe 12 enough make underground water collect rapidly to return to, in inspection shaft, reach
To quick release hydraulic pressure, it is to avoid the purpose that track structure floats.
It is provided with granular cushion 4, described inspection shaft base plate 2, granular cushion 4 below described inspection shaft base plate 2
Between be provided with loaded filter 3.
Described loaded filter 3 is geotextiles.
Described loaded filter 3 be prevented from tunnel subsoil stone particle blocking spilled water hole 1, with reach be effectively isolated, draining smoothly
Purpose.
Described overflow pipe 12 outer wall is provided with, with the contact site of spilled water hole 1 inwall, the rubber ring 13 sealing.
Described rubber ring 13 is prevented from water in inspection shaft 5 and enters tunnel bottom, so that certain pressure underground water is converged simultaneously
Return in inspection shaft 5 on collection, it is to avoid increase because of tunnel perimeter water level, hydraulic pressure increases, and lead to track structure to float deformation.
