Description
Technical field
The utility model relates to the filling system in a kind of urban subway tunnel excavation face, particularly a kind of front of tunnel heading water content of soil high and adopt deep hole sealing filling system.
Background technology
City underground shallow burial hidden digging is constructed, usually run into soil layer moisture abundant, soil layer is immersed in water for a long time, water saturation, the situation of soil body extremely unstable, and sealing object cannot be reached by conventional per-fore pouring liquid with small pipe, the situation that water burst gushes sand, the arch soil body caves in usually is run in digging process, anhydrous operating condition cannot be reached, can not construction safety be ensured, even affect structural safety.
Summary of the invention
The utility model provides a kind of deep hole sealing filling system, solves when metro tunnel excavation soil layer is moisture to be enriched and adopts conventional per-fore pouring liquid with small pipe cannot reach the technical problem of the solid soil of sealing.
The utility model solves above technical problem by the following technical programs:
A kind of deep hole sealing filling system, comprise tunnel construction tunnel face, tunnel construction tunnel face is provided with grouting and reinforcing solum, arrange in the front of grouting and reinforcing solum and need the grouting and reinforcing soil body, tunnel construction tunnel face on the solum of grouting and reinforcing arranged be provided with wall for grouting, wall for grouting is made up of mesh sheet and dry shotcreting layer, wall for grouting is evenly equipped with deep hole grouting hole, deep hole grouting hole is successively through wall for grouting be arranged on after grouting and reinforcing solum and treat in the grouting and reinforcing soil body, the degree of depth in deep hole grouting hole is 10-12 rice, hollow drill pipe Grouting Pipe is provided with in deep hole grouting hole, hollow drill pipe Grouting Pipe and slurry filling machine link together.
Tunnel construction tunnel face is provided with excavation to top bar and excavation is got out of a predicament or an embarrassing situation, is provided with firm soil body i iron of getting out of a predicament or an embarrassing situation excavating in the wall for grouting of getting out of a predicament or an embarrassing situation on facade, be provided with firm soil body i iron of topping bar excavating in the wall for grouting of topping bar on facade.
The utility model passes through the combination of deep hole grouting and wall for grouting, and the soil layer fixed to construction anterior instability carries out sealing grouting and reinforcing, thus reaches the execution conditions of the anhydrous operation of face, ensures construction operation safety and structural safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the distribution map of deep hole grouting hole 14 on wall for grouting 15;
Fig. 3 is the structural representation of wall for grouting 15.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of deep hole sealing filling system, comprise tunnel construction tunnel face, tunnel construction tunnel face is provided with grouting and reinforcing solum 12, arrange in the front of grouting and reinforcing solum 12 and need the grouting and reinforcing soil body 13, tunnel construction tunnel face on the solum of grouting and reinforcing 12 arranged be provided with wall for grouting 15, wall for grouting 15 is made up of mesh sheet and dry shotcreting layer, wall for grouting 15 is evenly equipped with deep hole grouting hole 14, deep hole grouting hole 14 is successively through wall for grouting 15 be arranged on after grouting and reinforcing solum 12 and treat in the grouting and reinforcing soil body 13, the degree of depth in deep hole grouting hole 14 is 10-12 rice, hollow drill pipe Grouting Pipe is provided with in deep hole grouting hole 14, hollow drill pipe Grouting Pipe and slurry filling machine link together.
Tunnel construction tunnel face is provided with excavation to top bar and excavation is got out of a predicament or an embarrassing situation, in the wall for grouting that excavation is got out of a predicament or an embarrassing situation on facade 2, be provided with firm soil body i iron 6 of getting out of a predicament or an embarrassing situation, in the wall for grouting that excavation is topped bar on facade 5, be provided with firm soil body i iron 7 of topping bar.
Tunnel construction tunnel face is provided with Tunnel 1, tunnel construction tunnel face is respectively arranged with excavation top bar, excavation is got out of a predicament or an embarrassing situation, relief groove and Core Soil, firm soil body i iron 6 of getting out of a predicament or an embarrassing situation is provided with on excavation gets out of a predicament or an embarrassing situation facade 2, the get out of a predicament or an embarrassing situation two ends of firm soil body i iron 6 are fixed together with Tunnel 1 respectively, facade mesh sheet 8 of getting out of a predicament or an embarrassing situation is coated with on excavation gets out of a predicament or an embarrassing situation facade 2, facade mesh sheet 8 of getting out of a predicament or an embarrassing situation is fixedly installed on excavation by anchor pole 12 and gets out of a predicament or an embarrassing situation on facade 2, firm soil body i iron 7 of topping bar is provided with on excavation tops bar facade 5, the top bar two ends of firm soil body i iron 7 are fixed together with Tunnel 1 respectively, facade mesh sheet 11 of topping bar is coated with on excavation tops bar facade 5, facade mesh sheet 11 of topping bar is fixedly installed on excavation by anchor pole and tops bar on facade 5, getting out of a predicament or an embarrassing situation in facade mesh sheet 8 and all dry layer of concrete being sprayed with 20 cm thicks in facade mesh sheet 11 of topping bar.
In the relief groove of relief groove, facade 3 is coated with facade mesh sheet 9 in relief groove, in relief groove, facade mesh sheet 9 to be fixed in relief groove on facade 3 by anchor pole, the Core Soil alien invasion 4 of Core Soil is coated with Core Soil alien invasion mesh sheet 10, Core Soil alien invasion mesh sheet 10 is fixed on Core Soil alien invasion 4 by anchor pole, in relief groove in facade mesh sheet 9 and Core Soil alien invasion mesh sheet 10 on all dry layer of concrete being sprayed with 20 cm thicks.
In wall for grouting of topping bar on facade of the present utility model, the wall for grouting of getting out of a predicament or an embarrassing situation on facade, relief groove, the wall for grouting on facade and the wall for grouting on Core Soil alien invasion form wall for grouting 15 complete on face jointly, reinforcement has been carried out on the surface of the open face facade soil body, what make front of tunnel heading treats that the slip casting soil body forms the closed soil body that can carry certain pressure, make the pressure of deep hole grouting give play to effect better, be conducive to the discharge treating water in the slip casting soil body.
