Description
Technical field
The present invention relates to a kind of vertical shaft surrounding rock supporting structure and its excavation supporting methods.Suitable for using combined bolting and shotcrete and steel
Reinforced concrete liner 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
The technical problem to be solved by the present invention is in view of the above problems, it is simple, easy for construction to provide a kind of structure
Vertical shaft surrounding rock supporting structure and its excavation supporting method to guarantee that vertical shaft internal environment is dry guarantee the safety and stability of vertical shaft
Operation.
The technical scheme adopted by the invention is that: a kind of vertical shaft surrounding rock supporting structure, it is characterised in that: in the borehole wall of vertical shaft
On be provided with a circle groove at spacing intervals, construction has system anchor bolt in the country rock around vertical shaft, and system anchor bolt is integrally located at
In country rock；Ecto-entad is successively arranged concrete layer, compound water-proof and reinforced concrete lining layer in the vertical shaft, wherein coagulation
Soil 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 groove one
One corresponding support ring.
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 present invention are: the present invention is directed to the contradiction between shaft support and antiseepage, by certain along the borehole wall
One circle groove of spacing setting, groove is interior to be poured together according to Structure Calculation result arrangement of reinforcement and with borehole wall reinforced concrete lining layer, is increased
The strong supporting effect of the borehole wall, the exposed effect of alternative system anchor bolt, therefore this excavation supporting method is used, system anchor bolt can
It is not exposed, so as to be laid with compound water-proof along borehole wall large area, stop wall leakage, both meets the requirement of vertical shaft adjoining rock stability,
Guarantee borehole wall anti-seepage effect again.
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 present invention, and the present invention is also not limited to the example above, the art
Those of ordinary skill, within the scope of the invention, variation, addition or the replacement made all should belong to protection scope of the present invention.
