Abstract
The utility model is related to a kind of drainage arrangements suitable for the infiltration of diversion tunnel occluding body construction time high pressure, belong to hydraulic and hydroelectric engineering field.The utility model includes concrete occluding body, the rockfill grouting pipe of connection irrigation gallery is equipped in concrete occluding body, the top layout of concrete occluding body has drainpipe, drainpipe to be arranged along concrete occluding body length direction, and multiple osculums are arranged at intervals on drainpipe.Drainpipe is more, is arranged along the contour line interval of concrete occluding body crown.When concrete occluding body seeps water, it is in the milk by original rockfill grouting pipe in concrete occluding body, high pressure water is discharged by drainpipe, after the completion of last concrete occluding body rockfill grouting, drainpipe is closed using high-pressure grouting, infiltration is effectively intercepted, occluding body maintenance quality is improved, ensures that occluding body downstream construction safety carries out.
Description
Technical field
The utility model is related to a kind of drainage arrangements suitable for the infiltration of diversion tunnel occluding body construction time high pressure, belong to water conservancy
Hydroelectric project field.
Background technology
The diversion tunnel of hydraulic and hydroelectric engineering need to be blocked after completing water conservancy diversion task with permanent concrete occluding body,
Occluding body is linked to be entirety, shared water pressure with country rock or lining cutting in the process of running.In general, occluding body lock under diversion tunnel
After start to construct, mainly include concreting and maintenance, during occluding body concrete curing, by Temperature Controlling of Mass Concrete
Measure restricts, and periphery rockfill grouting must lag construction.However, with the raising of upstream water level, under great head pressure, envelope
Stifled body periphery is likely to occur high pressure infiltration, and normal pressures grouting effect is little, once occur by the maintenance of occluding body and under
Trip protected object normal construction impacts.
Utility model content
Technical problem to be solved in the utility model is：Concentration ejectment is carried out to infiltration using drainpipe, then to collection
Middle ejectment pipeline carries out the thinking of grout sealing, intends providing a kind of draining suitable for the infiltration of diversion tunnel occluding body construction time high pressure
Device, the structure simple structure are easy for construction.
Technical solution used by the utility model is to solve above-mentioned technical problem：Body construction is blocked suitable for diversion tunnel
The drainage arrangement of phase high pressure infiltration, including concrete occluding body, the interior backfill for being equipped with connection irrigation gallery of concrete occluding body fill
The top layout of slurry pipe, concrete occluding body has drainpipe, drainpipe to be arranged along concrete occluding body length direction, drainpipe
On be arranged at intervals with multiple osculums.
It is further：Drainpipe is more, is arranged along the contour line interval of concrete occluding body crown.
It is further：Drainpipe is steel pipe.
It is further：Pipe diameter is 80mm~100mm, and thickness of steel pipe is 1mm~2mm.
It is further：A diameter of 5mm~the 10mm of osculum, spacing are 10cm~20cm.
The utility model has the beneficial effects that：When concrete occluding body seeps water, by original in concrete occluding body
Rockfill grouting pipe is in the milk, and high pressure water is discharged by drainpipe, after the completion of last concrete occluding body rockfill grouting, using height
Pressure grouting closing drainpipe, effectively intercepts infiltration, improves occluding body maintenance quality, ensures that occluding body downstream construction safety carries out.
Description of the drawings
Fig. 1 is the longitudinal sectional drawing of the utility model；
Fig. 2 is the structural schematic diagram of drainpipe；
It is marked in figure：1- concrete occluding body, 2- irrigation galleries, 3- rockfill groutings pipe, 4- drainpipes, 5- osculums, 6-
Diversion tunnel lining cutting.
Specific implementation mode
For ease of understanding with implementation the utility model, it is described further with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, the utility model includes concrete occluding body 1, and connection grouting is equipped in concrete occluding body 1
The top layout of the rockfill grouting pipe 3 of gallery 2, concrete occluding body 1 has drainpipe 4, and drainpipe 4 is along concrete occluding body 1
Length direction is arranged, multiple osculums 5 are arranged at intervals on drainpipe 4.Drainpipe 4 is more, is pushed up along concrete occluding body 1
The contour line interval of arch is arranged.Drainpipe 4 preferably uses steel pipe.Pipe diameter be 80mm~100mm, thickness of steel pipe be 1mm~
2mm.The quantity of drainpipe 4 is selected according to water percolating capacity size.In addition, a diameter of 5mm~10mm of osculum 5, spacing 10cm
~20cm.
When encountering high pressure infiltration, first in the irrigation gallery 2 of concrete occluding body 1, by pre- in concrete occluding body 1
The rockfill grouting pipe 3 buried is in the milk to periphery fissure, and grouting pressure is slightly larger than head pressure, and high pressure infiltration is made to pass through osculum 5
It is pooled to drainpipe 4 and concentrates ejectment, after the completion of waiting for rockfill grouting, in 4 exit of drainpipe, blocked using high-pressure grouting.
By the way that drainpipe 4 is arranged, seeps water to high pressure and effectively block, improve occluding body maintenance quality, ensure occluding body downstream
Construction safety carries out.
