Abstract
The invention discloses a tunnel inspection well with draining and floating resisting functions. The tunnel inspection well comprises an inverted arch filling layer, a tunnel inverted arch and a center draining pipe arranged in the inverted arch filling layer. An inspection well body is formed in the inverted arch filling layer. The inspection well body passes through the tunnel inverted arch in depth. Draining holes are reserved in an inspection well bottom plate of the inspection well body. Overflow pipes are inserted into the draining holes. The side wall of the inspection well body communicates with the center draining pipe. The tunnel inspection well is applicable to railway tunnel engineering in water-rich sections such as faults and karst development sections, the situation that due to the fact that base water pressure in a tunnel is too high, a ballastless track arches up can be effectively prevented, and safe operation of a railway is guaranteed. The tunnel inspection well has the beneficial effects of simple construction, small investment and the like, the application prospect is wide, construction operation is very simple, and the construction cost is extremely low.
Description
Technical field
The invention belongs to a kind of tunnel inspection shaft, be specifically related to a kind of tunnel inspection shaft with sluicing anti-floating function.
Background technology
At present, China be that Tunnel Engineering is largest in the world, quantity at most, geological conditions and version the most multiple
Country miscellaneous, that technology of building is with the fastest developing speed.For railway tunnel, mostly use and center is set in inverted arch packed layer
Water pipe, as the drainage pattern of main drainage channel, keeps at a certain distance away simultaneously and arranges center inspection shaft at, in order to desilting, white-out
Central water tube, meets the requirement that tunnel drainage system " can be safeguarded ".It addition, along with the development of high-speed railway, for satisfied row
Overall height speed service requirement, generally starts in high ferro tunnel to lay non-fragment orbit.Compared with traditional Ballast track, although without tiny fragments of stone, coal, etc. rail
Road can reduce maintenance, reduction dust, beautify the environment, but the stability requirement to tunnel bottom structure is the highest.
But, in the last few years, the railway tunnel of operation, at the water abundant ground such as tomography, karsts developing area, owing to hydraulic pressure is high, causes
The phenomenon of non-fragment orbit arch occurs repeatedly；Further, since problems such as constructing tunnel technique, construction qualities, cause tunnel inverted arch
It is more universal that the situations such as layering performs and inverted arch construction joint waterproof effect is undesirable filled by bottom leakiness, inverted arch, if tunnel
Road periphery subsoil water is grown, the water yield is enriched, and the weak location of these guarded drainage will produce hydrops, under hydraulic pressure effect, causes
The protuberance of track plates, causes extreme influence to safety of railway operation.
Summary of the invention
The present invention solves that problem that prior art exists proposes, its objective is to provide one to have sluicing anti-floating function
Tunnel inspection shaft.
The technical scheme is that a kind of tunnel inspection shaft with sluicing anti-floating function, including inverted arch packed layer, tunnel
Road inverted arch and be arranged on the central drainage pipe in inverted arch packed layer, forms inspection shaft, described inspection in described inverted arch packed layer
Well depth crossing-river tunnel inverted arch, in the inspection shaft base plate of inspection shaft, reserved spilled water hole, is inserted with overflow pipe in described spilled water hole, described
Inspection shaft sidewall connects with central drainage pipe.
Granular cushion it is provided with, 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 overflow pipe outer wall is provided with, with the contact site of spilled water hole inwall, the rubber ring sealed.
Described overflow pipe fixes with inspection shaft sidewall.
Described overflow pipe pipe is risen in drain pipe.
Described inspection shaft sidewall is formed foot nest, and is provided with reinforcing bar cat ladder.
Described inspection shaft opening is provided with cover plate.
The present invention is be applicable to the water abundant ground railway tunnel work such as tomography, karsts developing area, in effectively preventing tunnel
Causing greatly non-fragment orbit to arch up because sole presses through, ensured the safe operation of railway, the present invention has that construction is simple, it is little to invest
Etc. feature, having a extensive future, constructing operation is very simple, and construction costs is extremely low.

Detailed description of the invention
Hereinafter, referring to the drawings and embodiment the present invention is described in detail:
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 with
And the central drainage pipe 8 being arranged in inverted arch packed layer 6, described inverted arch packed layer 6 is formed inspection shaft 5, described inspection shaft 5 is deep
Degree crossing-river tunnel inverted arch 7, i.e. inspection shaft base plate 2 are arranged at below tunnel inverted arch 7 bottom surface, pre-in the inspection shaft base plate 2 of inspection shaft 5
Staying spilled water hole 1, be inserted with overflow pipe 12 in described spilled water hole 1, described inspection shaft 5 sidewall connects with central drainage pipe 8.
Spilled water hole 1 in inspection shaft base plate 2 and overflow pipe 12 enough make subsoil water collect rapidly to return to, in inspection shaft, reach
To quick pressure release, it is to avoid the purpose that track structure floats.
Granular cushion 4, described inspection shaft base plate 2, granular cushion 4 it is provided with below described inspection shaft base plate 2
Between be provided with loaded filter 3.
Described loaded filter 3 is geotextiles.
Described loaded filter 3 is prevented from tunnel subsoil stone granule blocking spilled water hole 1, to reach to 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 sealed.
In described rubber ring 13 is prevented from inspection shaft 5, water enters at the bottom of tunnel, makes certain pressure subsoil water to converge simultaneously
Return in inspection shaft 5 on collection, it is to avoid because of tunnel perimeter water level increase, hydraulic pressure increase, and cause track structure float deformation.
Described overflow pipe 12 fixes with inspection shaft 5 sidewall.
Described overflow pipe 12 pipe is risen in drain pipe.Making charge for remittance one-way flow, in being prevented effectively from gutter, charge for remittance is by inspection
Look into well 5 to Tunnel Base seepage.
