Abstract
The utility model relates to a kind of vertical shaft surrounding rock supporting structures.The purpose of the utility model is to provide a kind of structures, and vertical shaft surrounding rock supporting structure simple, easy for construction guarantees the safe and stable operation of vertical shaft to guarantee that vertical shaft internal environment is dry.The technical solution of the utility model is: a kind of vertical shaft surrounding rock supporting structure, it is characterised in that: is provided with a circle groove at spacing intervals on the borehole wall of vertical shaft, construction has system anchor bolt in the country rock around vertical shaft, and system anchor bolt is integrally located in country rock；Ecto-entad is successively arranged concrete layer, compound water-proof and reinforced concrete lining layer in the vertical shaft, wherein concrete layer is close to shaft wall setting and is formed by shotcrete with mesh, and reinforced concrete lining layer outer wall is formed with and the one-to-one support ring of the groove.The utility model is suitable for using combined bolting and shotcrete and reinforced concrete lining layer supporting, and borehole wall large area seeps water and water is larger, the excavation supporting of the vertical shaft more demanding to running environment.
Description
Technical field
The utility model relates to a kind of vertical shaft surrounding rock supporting structures.Suitable for using combined bolting and shotcrete and reinforced concrete lining layer
Supporting, borehole wall large area seeps water and water is larger, the excavation supporting of the vertical shaft more demanding to running environment.
Background technique
With the rapid development of underground engineering construction in recent years, such as underground workshop, buried mining, underground
Laboratory etc. generally requires and meets the functions such as communications and transportation, transmission of electricity ventilation by excavating shaft, according to the difference of vertical shaft function,
Some vertical shafts must keep drying, and the borehole wall must not have infiltration.
Outlet vertical shaft often passes through ground mulching layer, highly weathered rock mass and interlayer weakness band, and rock mass is relatively broken, needs to tie
It closes some supports means such as pneumatically placed concrete, system anchor bolt and reinforced concrete lining layer and guarantees vertical shaft adjoining rock stability, generally adopt at present
It is exposed with system anchor bolt, the way enhancing supporting construction globality of reinforced concrete lining layer is poured into, guarantees supporting effect.But one
As rock crushing, develop containing interlayer weakness band area underground water, underground water easily oozes out along the borehole wall, due to system anchor bolt outside
Dew can not be laid with compound water-proof along borehole wall large area, and borehole wall anti-seepage effect is poor, influences the safe and stable operation of vertical shaft.
Summary of the invention
Technical problem to be solved by the utility model is: in view of the above problems, provide that a kind of structure is simple, construction
Convenient vertical shaft surrounding rock supporting structure guarantees the safe and stable operation of vertical shaft to guarantee that vertical shaft internal environment is dry.
The technical scheme adopted by the utility model is a kind of vertical shaft surrounding rock supporting structure, it is characterised in that: in vertical shaft
A circle groove is provided on the borehole wall at spacing intervals, construction has system anchor bolt in the country rock around vertical shaft, and system anchor bolt is whole
In country rock；Ecto-entad is successively arranged concrete layer, compound water-proof and reinforced concrete lining layer in the vertical shaft, wherein
Concrete layer be close to shaft wall setting and formed by shotcrete with mesh, reinforced concrete lining layer outer wall be formed with it is described recessed
The one-to-one support ring of slot.
A kind of excavation supporting method of vertical shaft surrounding rock supporting structure, it is characterised in that steps are as follows:
A, at spacing intervals in the one circle groove of shaft wall setting during shaft excavation；
B, it constructs after the completion of shaft excavation the system anchor bolt, system anchor bolt is integrally located in the country rock around vertical shaft；
C, shotcrete with mesh forms the concrete layer on shaft wall；
D, it is close to concrete layer and one layer of compound water-proof is set；
E, the construction reinforced concrete lining layer.
The beneficial effects of the utility model are: the utility model passes through edge for the contradiction between shaft support and antiseepage
One fixed spacing of borehole wall setting, one circle groove, in groove according to Structure Calculation result arrangement of reinforcement and and borehole wall reinforced concrete lining layer together
It pours, enhances the supporting effect of the borehole wall, the exposed effect of alternative system anchor bolt, therefore use this excavation supporting method, be
Uniting anchor pole can not be exposed, so as to be laid with compound water-proof along borehole wall large area, stops wall leakage, it is steady both to have met vertical shaft country rock
Provisioning request, and guarantee borehole wall anti-seepage effect.
Detailed description of the invention
Fig. 1 is the sectional side elevation of embodiment.
Fig. 2 is the cross sectional view of embodiment.
Specific embodiment
As shown in Figure 1 and Figure 2, the present embodiment is a kind of vertical shaft surrounding rock supporting structure, every certain on the borehole wall of vertical shaft 6
Spacing excavation is formed with a circle groove 5, and construction has system anchor bolt 1 in the country rock around vertical shaft 6, and system anchor bolt 1 is integrally located at
In country rock, which is not exposed in vertical shaft 6.Ecto-entad is successively arranged concrete layer 2, compound water-proof 3 and steel in vertical shaft 6
Reinforced concrete lining cutting 4, wherein concrete layer 2 and compound water-proof 3 are close to 6 borehole wall of vertical shaft arrangement, and recessed on the corresponding borehole wall 6
5 position of slot is formed with corresponding slot, and 4 outer wall of reinforced concrete lining layer is formed with and the one-to-one support ring 401 of groove 5.
Compound water-proof 3 constitutes borehole wall waterproof construction in this example, stops wall leakage.The general Ying Yugu of compound water-proof 3
Knot grouting, grout curtain, System drainage hole, plastic blind-ditch, draining steel pipe etc. are applied in combination.
The construction method of the present embodiment is as follows:
A, at spacing intervals in 6 borehole wall of vertical shaft setting, one circle groove 5 in 6 digging process of vertical shaft；
B, construction system anchor pole 1 after the completion of vertical shaft 6 excavates, system anchor bolt 1 are integrally located in the country rock around vertical shaft 6, anchor
Bar is not exposed in vertical shaft 6；
C, shotcrete with mesh forms concrete layer 2 on 6 borehole wall of vertical shaft, guarantees that hole wall is smooth；
D, it is close to concrete layer 2 and one layer of compound water-proof 3 is set；
E, construction reinforced bar concrete lining 4, should be according to Structure Calculation result arrangement of reinforcement when the groove 5 of the borehole wall 6 backfills, and and well
Wall reinforced concrete lining layer 4 pours together becomes whole.
Certainly, above description is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
The those of ordinary skill in art field, in the scope of the utility model, variation, addition or the replacement made all should belong to this reality
With novel protection scope.
