Abstract
The utility model discloses a device is arranged in accuse of tunnel groundwater. Leading water pipe, gate valve, connection elbow, check valve and drain pipe including order UNICOM, leading water pipe overcoat have the mould bag, and the horizontal position that check valve and drain pipe formed is less than the horizontal position of leading water pipe and gate valve formation, the leading water pipe installation is located the diversion tunnel bottom plate, below the structrual concrete, there is the sump pit drain pipe export below, the mould bag is single hop or multistage structure to through mould bag grout pipe and grouting equipment UNICOM. The utility model discloses concentrating a water spot check valve and drawing row device and uses simultaneously through the large -scale stifled water film bag and the function of check valve, fill the water electricity generation phase at diversion tunnel and directly will go out in the log raft advances the tunnel, because the effect of check valve, the tunnel is crossed flowing water and can not exosmosed to the apopore in.
Description
Technical field
The utility model belongs to constructional engineering drain technical field, the particularly underground water control of a kind of tunnelArranging device.
Background technology
In the engineering constructions such as extensive water conservancy project, Highway Tunnel, usually there is water burst phenomenon, to large faceLong-pending water outlet, be loose shape and go out water problems, the drainage system of independent permanent operation need to be set.
Existing drainage pattern comprises natural drainage and mechanical draining, and in general construction, water discharge method has utilizationThe base tunnel draining of gravity Natural excrement, boring draining and utilize the forced drainage method of well point. These rowsWater method is not suitable for diversion tunnel inner high voltage, large flow water outlet, cannot realize " interior water do not exosmose,Outer water oozes in not " control row object.
Summary of the invention
The utility model discloses the underground water control arranging device of a kind of tunnel according to the deficiencies in the prior art. ThisThe problem that utility model will solve is to provide a kind of control row who realizes large flow, high pressure underground water, fallsBigcatkin willow pressure under lowland, guarantees the underground water control arranging device of tunnel of diversion tunnel structural safety.
The utility model is achieved through the following technical solutions:
The underground water control arranging device of tunnel, comprises aqueduct, gate valve, bridge piece, non-return valve and drainingPipe, is characterized in that: described aqueduct, gate valve, bridge piece, non-return valve and drainpipe order connectionLogical; Aqueduct overcoat has mould bag, and the horizontal level that non-return valve and drainpipe form is lower than aqueduct and lockThe horizontal level that valve forms;
Described aqueduct is positioned at diversion tunnel base plate, below structural concrete;
There is catch pit described drainpipe outlet below.
Described mould bag is single hop or multi-segment structure, and by mould bag grout pipe and grouting equipment UNICOM.
The underground water control arranging device of the utility model tunnel is installed method to set up: on ejectment hole, install largePattern bag, adopts seamless steel pipe to be connected with ejectment casement bag gate valve, and underground water is caused to the reserved collection of base plateIn puddle, non-return valve is installed in exit, non-return valve exports higher than underplate concrete lining 5cm.
The utility model remains that in ejectment water work progress its ejectment hole underground water is in discharge shapeState, directly arranges water outlet in tunnel in the generating of diversion tunnel water-filling the phase, realized " interior water do not exosmose,Outer water oozes in not " control row object.
The utility model helpfulness is: be greater than 500L/s at diversion tunnel single-point water yield, pressure is greater thanWhen 0.5MPa, directly shutoff may threaten to the structural safety of tunnel. The utility model is concentratedEXIT POINT non-return valve ejectment device is exactly by function the use of large-scale water blockoff film bag and non-return valve, is drawingThe water tunnel water-filling generating phase directly arranges water outlet in tunnel, due to the effect of non-return valve, and tunnel overcurrentWater can not be seeped in apopore outside.
Brief description of the drawings
Fig. 1 the utility model device sectional structure schematic diagram.
In figure. The 1st, aqueduct, the 2nd, mould bag, the 3rd, gate valve, the 4th, mould bag grout pipe, the 5th, connectBend pipe, the 6th, non-return valve, the 7th, drainpipe.
Detailed description of the invention
Below by embodiment, the utility model is specifically described, embodiment is only for to this realityBe further detailed with novel, can not be interpreted as the restriction to the utility model protection domain, thisSome nonessential improvement that the technical staff in field makes according to content of the present utility model and adjustment are alsoBelong to the scope of the utility model protection.
In conjunction with Fig. 1.
The underground water control arranging device of tunnel, comprise order UNICOM aqueduct 1, gate valve 3, bridge piece 5,Non-return valve 6 and drainpipe 7, aqueduct 1 overcoat has mould bag 2, and non-return valve 6 and drainpipe 7 formThe horizontal level that horizontal level forms lower than aqueduct 1 and gate valve 3;
Aqueduct 1 is positioned at diversion tunnel base plate, below structural concrete; Under drainpipe 7 outletsThere is catch pit side.
Mould bag 2 can be single hop or multi-segment structure, and by mould bag grout pipe 4 and grouting equipment UNICOM.In this illustration, mould bag 2 is multi-segment structures.
As shown in the figure, the underground water control arranging device installation of this routine tunnel method to set up is: ejectment hole is arrangedBelow diversion tunnel base arrangement concrete, determine behind ejectment hole site, on ejectment hole, Φ is installedThe large pattern bag 2 of 273mm, adopts Φ 273mm seamless steel pipe to be connected with ejectment casement bag gate valve 3, by groundLower water causes in the reserved catch pit of base plate, and Φ 273mm non-return valve 6 is installed in exit, and non-return valve 6 goes outMouth is higher than underplate concrete lining 5cm. Conventionally for
The utility model remains that in ejectment water work progress its ejectment hole underground water is in discharge shapeState, directly arranges water outlet in tunnel in the generating of diversion tunnel water-filling the phase, realized " interior water do not exosmose,Outer water oozes in not " control row object.
The design of the utility model mould bag, non-return valve meets the requirement of tunnel actual profile size, installsAfter can ensure building of structural concrete; Can make to concentrate EXIT POINT water outlet to be all pooled in mould bag,Realize and control discharge by non-return valve; Non-return valve adopts the manufacture of all steel material, meets at right angle settingRequirement, operating pressure must meet ejectment needs; Can serve as the independent permanent operation of independent structure. ThisUtility model is by function the use of large-scale water blockoff film bag and non-return valve, in the diversion tunnel water-filling generating phaseDirectly water outlet is arranged in tunnel, due to the effect of non-return valve, tunnel is crossed flowing water and can be seeped into out outsideIn water hole.
