Abstract
The utility model is related to the supporting construction of cylinder type surge-chamber big well in underground on Hydraulic and Hydro-Power Engineering, especially a kind of inter-laminar dislocation band.The purpose of this utility model is the supporting construction for proposing cylinder type surge-chamber big well in underground on a kind of simple, effective inter-laminar dislocation band, to ensure the adjoining rock stability of the upper and lower disk of inter-laminar dislocation band in the big well of surge-chamber.The technical solution of the utility model is：The protection structure includes the vertical big well of surge-chamber, the top of the big well of surge-chamber is surge-chamber dome, one inter-laminar dislocation band is right through the big well of surge-chamber, the inter-laminar dislocation band is divided into along slope inter-laminar dislocation band and counter-slope inter-laminar dislocation band by the big well of the surge-chamber, it is characterized in that, on along slope intercalated dislocation band, the supporting anchorage cable of inter-laminar dislocation band is arranged through；On counter-slope intercalated dislocation band, supporting anchorage cable is arranged in the upper disk rock mass and lower wall rock mass of inter-laminar dislocation band respectively.The utility model is applied to the big well of underground cylinder type surge-chamber being located on intercalated dislocation band.
Description
Technical field
The utility model is related to Hydraulic and Hydro-Power Engineering, cylinder type surge-chamber big well in underground on especially a kind of inter-laminar dislocation band
Supporting construction.Suitable for the big well of underground cylinder type surge-chamber being located on intercalated dislocation band.
Background technology
In the digging process of Hydraulic and Hydro-Power Engineering, in addition to conventional system supporting, the hand-manipulating of needle can be all entered for structural plane
To the anchoring support of property, larger structure face can typically increase cable bolting.Inter-laminar dislocation band is used as the structural plane between a kind of rock stratum
In the big well of cylinder type surge-chamber during exposure, usual half is that second half is counter-slope form along domatic state, in order to ensure interlayer is wrong
It is dynamic take, the stabilization of lower wall rock mass structure, cable bolting targetedly need be carried out to the inter-laminar dislocation band along slope, counter-slope.
The content of the invention
For above-mentioned situation, the technical problems to be solved in the utility model is：Propose a kind of simple, effective intercalated dislocation
The supporting construction of the big well of underground cylinder type surge-chamber is taken, to ensure the country rock of the upper and lower disk of inter-laminar dislocation band in the big well of surge-chamber
It is stable.
The technical scheme that the utility model is used is：The supporting knot of the big well of underground cylinder type surge-chamber on inter-laminar dislocation band
Structure, including the vertical big well of surge-chamber, the top of the big well of surge-chamber is surge-chamber dome, and an inter-laminar dislocation band is right through tune
The inter-laminar dislocation band is divided into along slope inter-laminar dislocation band and counter-slope inter-laminar dislocation band by the big well of pressure chamber, the big well of the surge-chamber, and it is special
Levy and be, on along slope intercalated dislocation band, be arranged through the supporting anchorage cable of inter-laminar dislocation band；On counter-slope intercalated dislocation band, point
Supporting anchorage cable is not arranged in the upper disk rock mass and lower wall rock mass of inter-laminar dislocation band.
The beneficial effects of the utility model are：This supporting construction be conventional high side wall cable bolting design on the basis of,
With reference to the actual conditions of inter-laminar dislocation band exposure in the big well of cylinder type surge-chamber, the more effective supporting side of proposition
Case, is applied, it is ensured that surge-chamber great Jing middle levels through being tested in certain western big well excavation and support processes of large hydropower station surge-chamber
Between the upper and lower disk of disturbed belt adjoining rock stability, effect is notable.
Brief description of the drawings
Fig. 1 is the schematic diagram of the big well cable bolting of the utility model cylinder type surge-chamber.
Fig. 2 is the upper and lower disk anchor cable spread figure of inter-laminar dislocation band of the big well of cylinder type surge-chamber.
Fig. 3 is the partial enlarged drawing of A types anchor cable arrangement (along domatic state) in Fig. 2.
Fig. 4 is the partial enlarged drawing of Type B anchor cable arrangement (counter-slope form) in Fig. 2.
Embodiment
As Figure 1-4, this example has the supporting construction of the big well of underground cylinder type surge-chamber on the present embodiment inter-laminar dislocation band
There is the big well 2 of surge-chamber of vertical direction, the top of the big well of surge-chamber is surge-chamber dome 1.One inter-laminar dislocation band 3 right through
The stage casing of the big well 2 of surge-chamber, makes the part rock mass be divided into disk rock mass and lower wall rock mass, and the surrounding rock stability to hole section is produced
Influence.
In the big well of cylinder type surge-chamber, it is along slope portion that the exposure position of inter-laminar dislocation band 3, which is divided into two parts, i.e. half,
Point, second half is counter-slope part, therefore support pattern should also be treated with a certain discrimination.The present embodiment is adopted for the inter-laminar dislocation band 3 along slope
Supporting anchorage cable 4 is taken to pass through the arrangement (as shown in Figure 3) of inter-laminar dislocation band 3；For the inter-laminar dislocation band 3 of counter-slope, take point
The mode of supporting anchorage cable 4 is not arranged in upper disk rock mass and lower wall rock mass.
Thus, the utility model ensure that the Stability Analysis of Structures of the upper and lower disk rock mass of inter-laminar dislocation band.
Claims (1)
1. the supporting construction of the big well of underground cylinder type surge-chamber on a kind of inter-laminar dislocation band, including the vertical big well of surge-chamber (2),
The top of the big well of surge-chamber is surge-chamber dome (1), and an inter-laminar dislocation band (3) is right through the big well of surge-chamber (2), the pressure regulation
