Embodiment
With reference to the accompanying drawings and embodiments, the technical solution of the utility model is described in detail.
The utility model is made of certainly components such as water control valve 100, Y-type pipe filter 200, adjustable drain valves 300
Dynamic pressure regulation water draw-off, subsurface flow direction carry out as shown in Figure 1, connection lining cutting behind seepage action of ground water pipe on the left of the device
Road, right side connection tunnel lateral direction drainpipe.Automatic Regulation water draw-off need to carry out during constructing tunnel it is pre-buried, could be complete
Into the pressure regulation sluicing function of underground water, which needs to carry out size and Functional Design according to tunnel-liner inner space.According to
Different project profiles can formulate different specifications and models, and the mountain tunnel of high hydraulic pressure hydrous fluids often uses underground water pipeline diameter
For 100mm, shown the utility model provides that the scope of draining aperture D is 80mm-120mm.
(1) automatic Regulation water draw-off size can be adjusted according to Tunnel Engineering structure size, length：B=B1+B2+
B3=62~78cm, height：≤ 38cm, width：20cm~25cm；In Fig. 1,2 be the external pressure gauge of drain valve.
(2) automatic Regulation water draw-off component function designs：
Component 1-- water control valves：Function is mainly temporary close, cut-out and throttling in underground water pipeline, easy to service
Chimney filter clears up the later stage maintenance of impurity and drain valve.Filter is likely to occur seepy question, it is necessary to clear up filter core net or replacement
Slag-drip opening；Drain valve is likely to occur valve body damage, destruction or pressure when failure behaviour, and corresponding portion need to be repaired or replaced
Part.See Fig. 2.Water control valve can make choice manual flange butterfly 1 or gate valve, width 8cm- according to headspace in tunnel
25cm, water control valve diameter D are consistent with subsoil drain.
Y-type pipe filter：Underground percolation water is likely to carry the impurity such as soil rubble in tunnel surrounding, mainly
For impurity such as the sand in filtering underground, gravels, in order to avoid block, damage drain valve.Critical piece has：Valve body 5, filter core net 4,
Slag-drip opening 6,7 etc. four parts of capping composition.Automatic Regulation water draw-off operation a period of time is, it is necessary to periodic cleaning filter interior
Impurity in filter cylinder.See Fig. 3.
When groundwater pressure exceedes drain valve setting pressure in tunnel, adjustable drain valve 300, which automatically turns on, to sluice, and protects
Card high pressure water enrichment tunnel-liner is born below critical hydraulic pressure condition, and tunnel overall structure is in stable state.Critical piece by
Main valve and exterior control pilot valve composition.
The utility model drain valve highest sluicing pressure threshold reaches as high as 1.6MPa, and ground water pressure needs to tie higher than this value
Close corresponding auxiliary grouting and water-proof measure.When tunnel groundwater enters drain valve, drain valve can pass through its internal pressure measurement
Device 2 measures hydraulic pressure value, if hydraulic pressure value exceeds drain valve setting value, drain valve meeting automatic drainage, until ground water pressure force value drops
Stop draining to setting value；If ground water pressure value is less than or equal to drain valve setting value, drain valve not draining.B3 length is：
≥29cm。
Generally stitched in the percolating water phenomenon of high pressure water enrichment Tunnel Engineering by construction Deformation, at subsiding crack or reinforcing bar insertion
Exudation, so the waterproof of tunnel lining structure construction joint and deformation joint is emphasis and difficult point.(do not carried out during constructing tunnel
Second Lining Construction) present apparatus is mountable to high pressure water enrichment tunnel side wall foot limited drainage area；In operation tunnel engineering originally
Device needs pre-buried tunnel both sides cable trench bottom, is symmetrically arranged with tunnel center line, be not take up tunnel internal space or
Runway, is conveniently replaceable or repairs corresponding component.As shown in Figure 5-Figure 7.
Automatic Regulation water draw-off pipeline (water control valve end) is needed using positive three-way connection and tunnel ring at tunnel side wall
It is attached to blind pipe, longitudinal drainage pipe, it is ensured that independent underdrainage system is formed in a certain range of tunnel longitudinal direction, sees Fig. 7 institutes
Show.Transverse drain in device other end connection tunnel, centre drain is discharged into by underground water, while in high pressure water enrichment
Longitudinal drainage pipe both ends must be provided with longitudinal drainage blind pipe end socket, it is ensured that underground water is drained according to setting means.If tunnel is arranged
Water system is designed in centre drain, and gutter design and side, the device can also uses parallel with tunnel axis, it is only necessary to
Design and installation corner coupling head.
Mainly it is installed on tunnel profile at the positions such as Tunnel Lining Deformation seam, subsiding crack.According to tunnel groundwater
Amount control, selects different part dimensions and pressure to control, automatic Regulation water draw-off installation direction can be oblique with tunnel axis
Hand over, orthogonality relation.With tunnel axis oblique：Should be noted tunnel longitudinal direction ratio of slope direction, tunnel longitudinal drainage carries out from right to left,
Each draining unit three-way elbow one is scheduled on the updrift side of construction joint of tunnel.It is orthogonal with tunnel：Each draining unit three
Logical elbow is overlapped with construction joint of tunnel position.
Specific installation implements high pressure water enrichment tunnel automatic Regulation water draw-off and sets fixation to let out, it is necessary to precalculate analysis
Water valve value controls underground water restricted discharge, forms separate tunnel underdrainage system.The system can both reduce the tunnel-liner back of the body
Water pressure afterwards, ensures the safety of liner structure, and will not be made because of unconfined discharge Groundwater table and groundwater environment
Into the destruction that can not recover, protection Sui Zhi areas ecological environment.The device can realize that Tunnel Engineering design construction standard is true at the same time
" limited drainage " technical requirements of positive meaning, can obtain good economic and social profit.
Above-described embodiment is the preferable embodiment of the utility model, but the embodiment of the utility model and from above-mentioned
The limitation of embodiment, the change made under other any Spirit Essences and principle without departing from the utility model, modify, replace
Generation, combination, simplify, and should be equivalent substitute mode, is included within the scope of protection of the utility model.
