Abstract
One body swimming qi leel for pernicious gas tunnel reduces the born hydraulic pressure of pernicious gas tunnel groundwater discharge structure, to reduce Tunnel Engineering cost from four-way box to efficiently separate the pernicious gas in underground water.Including box body and silt filter plate in its inner cavity is fixedly installed, box cavity is separated into lower chamber and upper chamber by silt filter plate.It is provided with drainpipe in the lower chamber, which is located at the lower part of lower chamber, and upper end is then external by the top outlet box of lower chamber.Exhaust fitting is set on the roof of the upper chamber, and admitting pipe joint is set on the side wall of upper chamber.
Description
Technical field
The utility model is related to tunnels, more particularly to a kind of one body swimming qi leel for pernicious gas tunnel from four-way
Box, to carry out aqueous vapor separation, discharge to gas or hydrogen sulfide.
Background technology
Pernicious gas tunnel refers to building in containing the tunnel in gas or hydrogen sulfide stratum.If watt in tunnel in air
This or sulfureted hydrogen gas concentration are in a dangerous range, if meeting fire again, can be exploded.So pernicious gas tunnel
Road will be paid special attention to take precautions against gas gas or hydrogen sulfide gas explosion in construction.
China's demobilization is vast, usually needs to pass through coal measure strata or H 2 S-containing gas stratum in tunnel construction.In this feelings
Under condition, tunnel construction has to face various threats that gas or hydrogen sulfide are brought.Due to lacking experience, the gas in early stage tunnel
Or hydrogen sulfide problem is not affected by enough attention, causes some tunnels that gas or hydrogen sulfide body accident has occurred.With Tunnel Engineering
The intensification of bound pair gas understanding and being constantly progressive for precautionary technology, China is successfully passed through there are many tunnel rich in gas or vulcanization
The stratum of hydrogen and mined-out region.
Tunnel high methane or hydrogen sulfide body work area in the design, in order to avoid in stratum gas or hydrogen sulfide gas pour in
In tunnel, it is usually taken using totally-enclosed gas prevention or hydrogen sulfide lining cutting.Gas or hydrogen sulfide gas emission measure, generally in nothing
Using gas or hydrogen sulfide gas delivery pipe tunnel is discharged in gas or hydrogen sulfide gas by underground water section；There is underground water section,
Liner structure or so abutment wall lower outside is laid with longitudinal Permeable blind pipe, and underground water is deflected from containing gas or hydrogen sulfide gas location,
Aqueous vapor separation chamber is arranged in Permeable blind pipe terminal, and the gas isolated or hydrogen sulfide gas available pipe are drawn aloft puts outside hole
It dissipates.
The deficiencies in the prior art are mainly reflected in the location of rich groundwater, and usual non-gas or the lining cutting of hydrogen sulfide section are behind
Longitudinal drainage blind pipe and circle draining blind pipe be connected to lateral sulcus, lining cutting design when do not consider water pressure.But works as and use
After totally-enclosed gas or hydrogen sulfide lining cutting, liner structure just needs to consider that the effect of water pressure, lining cutting can structures because of the effect of hydraulic pressure
Reinforce very much, engineering economy is poor.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of one body swimming qi leels for pernicious gas tunnel
From four-way box the born water of pernicious gas tunnel groundwater discharge structure is reduced to efficiently separate the pernicious gas in underground water
Pressure, to reduce Tunnel Engineering cost.
Technical solution is as follows used by the utility model solves its technical problem：
The utility model is used for the one body swimming qi leel in pernicious gas tunnel from four-way box, it is characterized in that：Including box body and
Silt filter plate in its inner cavity is fixedly installed, box cavity is separated into lower chamber and upper chamber by silt filter plate；It is described
Drainpipe is provided in lower chamber, which is located at the lower part of lower chamber, and upper end is then by the top of lower chamber
Outlet box is external；Exhaust fitting is set on the roof of the upper chamber, and admitting pipe joint is set to the side wall of upper chamber
On.
The utility model has the beneficial effects that can be effectively to the gas or hydrogen sulfide gas progress aqueous vapor point in underground water
From reduction the born hydraulic pressure of pernicious gas tunnel groundwater discharge structure, to reduce Tunnel Engineering cost.
Description of the drawings
This specification includes following two width attached drawing：
Fig. 1 is sectional view of the one body swimming qi leel from four-way box that the utility model is used for pernicious gas tunnel；
Fig. 2 is sectional view of the one body swimming qi leel from four-way box that the utility model is used for pernicious gas tunnel；
Component and corresponding label are shown in figure：Box body 10, lower chamber 11, upper chamber 12, exhaust fitting 13, into
Water pipe head 14, drainpipe 15, dredging services aperture 16, silt filter plate 20.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
Referring to Figures 1 and 2, the one body swimming qi leel for pernicious gas tunnel of the utility model includes box from four-way box
10 inner cavity of box body is separated into lower chamber 11 by body 10 and the silt filter plate 20 being fixedly installed in its inner cavity, silt filter plate 20
With upper chamber 12.Drainpipe 15 is provided in the lower chamber 11, which is located under lower chamber 11
Portion, upper end are then drawn by the top of lower chamber 11 outside box body 10.Exhaust fitting is set on the roof of the upper chamber 12
13, admitting pipe joint 14 is set on the side wall of upper chamber 12.
Referring to Fig.1, the utility model is using the water principle different with gas or hydrogen sulfide gas severe, using Gravity Separation
Mode, gas or hydrogen sulfide gas and underground water are detached in box body 10.Underground water containing gas or hydrogen sulfide by
Admitting pipe joint 14 introduces in box body 10, and water enters lower chamber 11 through silt filter plate 20, then through 15 He of submersible type drainpipe
Pipeline leads to tunnel drainage ditch, gas or hydrogen sulfide gas and draws tunnel through exhaust fitting 13 and pipeline in upper chamber 12
Discharge.
Referring to Figures 1 and 2, the lower part of the lower chamber 11 is provided with dredging services aperture 16.
The one body swimming qi leel described above that the utility model only explain through diagrams for pernicious gas tunnel is from four-way
Some principles of box are not intended to the utility model being confined in shown and described concrete structure and the scope of application, therefore all
It is the corresponding modification for being possible to be utilized and equivalent, belongs to the apllied the scope of the claims of the utility model.
