Description
Technical field
The utility model relates to grouting device technical field, refers to especially a kind of high-pressure blast grouting device for tunnel and the reinforcing of underground construction weak surrounding rock.
Background technology
Current domestic shallow buried covered excavation tunnel engineering is in sand and the construction of sandy soil stratum, and the many employings of leading reinforcing set advanced tubule and spray mixes the slip casting of sealing face, use plain edition Double-liquid mud-injection pump when slip casting.This technique is higher to the requirement of strength of face sealing, has increased cost; Moreover the equipment dropping in construction is many, is subject to the restriction of place size; The slurry reaction time is long, tells on slow; While using this kind of equipment, on-the-spot necessary access electrical source of power, increases risk.
Utility model content
The utility model proposes a kind of high-pressure blast grouting device for tunnel and the reinforcing of underground construction weak surrounding rock, solved the problem that in prior art, the common Double-liquid mud-injection pump slurry reaction time is grown, tells on slowly, efficiency of construction is low.
The technical solution of the utility model is achieved in that a kind of high-pressure blast grouting device for tunnel and the reinforcing of underground construction weak surrounding rock, comprise serum pot, end cap has been threaded on described serum pot, described end cap is provided with high-pressure blast import, material inlet, auxiliary agent import and exhaust opening, high-pressure blast import, material inlet, auxiliary agent import and exhaust opening are equipped with valve, in described material inlet and auxiliary agent import, be equipped with flow gauge, described serum pot is provided with electronic display, described electronic display is connected by wire with described flow gauge, described serum pot lower end is provided with discharging opening, described discharging opening connects slurries conduit, between described discharging opening and slurries conduit, be provided with valve I.
As preferably, described serum pot lower end is provided with support.
As preferably, described electronic display is provided with battery case.
The utility model is for the high-pressure blast grouting device of tunnel and the reinforcing of underground construction weak surrounding rock, simple and reasonable, can well reach the effect of leading reinforcing, has improved efficiency of construction, has guaranteed construction speed; Can save face sealing in construction process, abolish two links, saving of work and time, has reduced construction cost, can well control the proportioning of raw material and auxiliary agent simultaneously, has improved the quality of slurries, easy cleaning again simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model for the high-pressure blast grouting device of tunnel and the reinforcing of underground construction weak surrounding rock.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
With reference to Fig. 1, this specific embodiment is by the following technical solutions: a kind of high-pressure blast grouting device of reinforcing for tunnel and underground construction weak surrounding rock, comprise serum pot 1, end cap 12 has been threaded on described serum pot 1, described end cap 12 is provided with high-pressure blast import 2, material inlet 3, auxiliary agent import 10 and exhaust opening 4, high-pressure blast import 2, material inlet 3, auxiliary agent import 10 and exhaust opening 4 are equipped with valve 9, in described material inlet 3 and auxiliary agent import 10, be equipped with flow gauge, described serum pot 1 is provided with electronic display, described electronic display is connected by wire with described flow gauge, described serum pot 1 lower end is provided with discharging opening 6, described discharging opening 6 connects slurries conduit 5, between described discharging opening 6 and slurries conduit 5, be provided with valve I7.
It should be noted that described serum pot 1 lower end is provided with support 8.
In addition, described electronic display is provided with battery case.
When the utility model uses, by flow gauge proportioning raw material and auxiliary agent, improve the quality of slurries, in the time cleaning, only end cap 12 need to have been unloaded by screw thread, just can clean.
This concrete enforcement is simple and reasonable, can well reach the effect of leading reinforcing, has improved efficiency of construction, has guaranteed construction speed; Can save face sealing in construction process, abolish two links, saving of work and time, has reduced construction cost, can well control the proportioning of raw material and auxiliary agent simultaneously, has improved the quality of slurries, easy cleaning again simultaneously
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
