Background technique
With the rapid development of hydraulic and hydroelectric engineering construction in recent years, the quantity of underground power house is more and more.Underground power house
Generally cable, which is led to ground, by outlet vertical shaft goes out the field of line, since cable undertakes the task of high voltage power transmission, it is desirable that outlet vertical shaft
Drying is kept, the borehole wall there must not be infiltration.Outlet vertical shaft often passes through ground mulching layer, highly weathered rock mass and interlayer weakness band,
Rock mass is relatively broken, rich groundwater, and underground water is easily oozed out along borehole wall Lining Crack and construction joint position, so that vertical shaft lining cutting will
Very big groundwater pressure is born, the safe and stable operation of outlet vertical shaft has been seriously affected, has all been new to engineering design and construction
Challenge.Most domestic power station vertical shaft is drained using water-permeable pipe (material) at present, but water-permeable pipe be bonded with palisades it is poor,
Drainage effect is undesirable.
Utility model content
The purpose of the utility model is to overcome disadvantage existing in the prior art, a kind of draining good seepage-proof property is provided
Power station outlet vertical shaft, the outlet vertical shaft internal environment is dry, can safe and stable operation.
To achieve the goals above, the technical solution adopted in the utility model is as follows:
Power station outlet vertical shaft with discharge structure, including the row being arranged between pit shaft shotcrete with mesh and lining cutting
The gutter of water french drain and wellbore bottom, wherein weeper drain include the annular french drain being distributed layer by layer along pit shaft height and
Along the vertical french drain of the circumferentially spaced-apart distribution of pit shaft；Vertical french drain is connected to each layer annular french drain and charge for remittance in weeper drain is final
It is expelled to gutter；The drainage hole that shotcrete with mesh is equipped with multiple circular pit shaft outer walls and is connected to annular french drain.
Further, composite water-proof is additionally provided between weeper drain and lining cutting and between shotcrete with mesh and lining cutting
Plate.
Further, fitting shaft in wall is additionally provided with the vertical drainage pipe in several docking gutters；It is equipped with and erects in lining cutting
The aqueduct for being correspondingly connected with to drainpipe and being connected to weeper drain.
Further, drainage hole integrally radially extends outwardly from shotcrete with mesh.
Further, the bottom end of vertical french drain is connected with drainage tube, and drainage tube passes through lining cutting and docks with gutter.
Further, compound water-proof is fixed by stainless steel strip and nailing with shotcrete with mesh.
Further, a length of 4.5m of drainage hole, aperture 50mm.
The technical solution of the utility model, by the way that circumferential and vertical french drain is arranged in well bore wall and drainage hole is combined to constitute
Effectively infiltration can be discharged in time for borehole wall discharge structure, and external vertical drainage pipe can then prevent the blocking of weeper drain,
It ensure that the dry environment in vertical shaft to whole to reduce design, the maintenance cost of vertical shaft lining cutting, enable and vertical shaft occur
It runs with security and stability；Meanwhile borehole wall waterproof construction is constituted to stop wall leakage, further in conjunction with the setting of compound water-proof
Drying in service shaft.

Specific embodiment
The utility model will be further described with reference to the accompanying drawing.
Referring to attached drawing.The shotcrete with mesh 2 that 8 outer layer of lining shaft of the utility model is equipped with a thickness of 15cm, linked network
Pneumatically placed concrete 2 guarantees that well bore wall is smooth.Weeper drain, wellbore bottom are provided between pit shaft shotcrete with mesh 2 and lining cutting 8
Gutter 12 is dug.Wherein, weeper drain include the annular french drain 5 being distributed layer by layer along pit shaft height and along pit shaft it is circumferential between
Every the vertical french drain 4 of distribution.Vertical french drain 4 is connected to each layer annular french drain 5 and is finally expelled to the charge for remittance in weeper drain
Ditch.The drainage hole 1 that shotcrete with mesh 2 is equipped with multiple circular pit shaft outer walls and is connected to annular french drain 4.Drainage hole 1 with
Weeper drain constitutes borehole wall discharge structure, is expelled in the gutter of silo bottom after wall leakage is collected.Specifically, it drains
Hole 1 a length of 4.5m, aperture 50mm, and it is whole in radial outward.
It is additionally provided with compound water-proof 3 between weeper drain and lining cutting 8 and between shotcrete with mesh 2 and lining cutting 8, is used for
Stop wall leakage, guarantee the drying in lining cutting 8 and pit shaft, forms the double action of antiseepage draining with borehole wall discharge structure.Its
In, compound water-proof 3 is fixed by stainless steel strip 11 and nailing 10 with shotcrete with mesh.Compound water-proof 3 with a thickness of
1.5mm。
Fitting shaft in wall is additionally provided with the vertical drainage pipes 7 in several docking gutters 12, is equipped in lining cutting 8 and vertical drainage
