Technical field
The present invention relates to a kind of fissure rock grouting reinforcement technology, relate in particular to a kind of fissure rock grouting reinforcement experiment instrument and experimental technique thereof.
Background technology
In subsurface rock engineerings such as mine, be distributed with the crack of certain density in the tunnel-surrounding country rock through regular meeting, particularly produced the tunnel of moderate finite deformation, crack density is bigger in its country rock.Wall rock grouting can these cracks of filling, and crack country rock filling is reinforced, and make it to be converted into complete rock mass.So just can fully improve the intensity of country rock.
For the grouting consolidation effect of measuring fissure rock, must in the laboratory, carry out the grouting and reinforcing of fissure rock easily, grouting serous fluid is fully injected fractured rock.
Experimental facilities of the prior art is divided into four parts, is respectively high-pressure nitrogen bottle, seals and put slurry device, reinforcing device and overflow mechanism.Regulate the nitrogen cylinder outlet pressure, slurry device entoplasm hydraulic pressure is put in sealing gone into reinforcing device, the reinforcing device inner chamber is placed with the reference block of breaking, and guarantees that slurries ooze the plane of fracture of people's test block, and overfall is realized slowly flowing of slurries.
At least there is following shortcoming in the above-mentioned prior art: experiment slurries and test sillar respectively in different containers, complex structure, inconvenient operation.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to operate fissure rock grouting reinforcement experiment instrument and experimental technique thereof.
The objective of the invention is to be achieved through the following technical solutions:
Fissure rock grouting reinforcement experiment instrument of the present invention comprises pressurizing chamber, slip casting chamber, is provided with piston between described pressurizing chamber and the slip casting chamber.
Fissure rock grouting reinforcement experimental technique of the present invention is used above-mentioned fissure rock grouting reinforcement experiment instrument and is carried out the fissure rock grouting reinforcement experiment, comprises step:
A, the fissure rock test specimen is put into the slip casting chamber, and will be full of slurries in the slip casting chamber, then the slip casting chamber is sealed;
B, to pressurizing chamber pressurization, piston passes to the slip casting chamber with pressure, and the crack rock sample is carried out slip casting.
As seen from the above technical solution provided by the invention, fissure rock grouting reinforcement experiment instrument of the present invention and experimental technique thereof, owing to comprise pressurizing chamber, slip casting chamber, be provided with piston between described pressurizing chamber and the slip casting chamber, during experiment, experiment slurries and experiment test specimen pressurize to pressurizing chamber with being placed in the slip casting chamber, piston passes to the slip casting chamber with pressure, and the crack rock sample is carried out slip casting.Simple in structure, easy to operate.
Description of drawings
Fig. 1 is the structural representation of fissure rock grouting reinforcement experiment instrument of the present invention.
The specific embodiment
Fissure rock grouting reinforcement experiment instrument of the present invention, its preferable specific embodiment comprise pressurizing chamber, slip casting chamber as shown in Figure 1, are provided with piston 1 between described pressurizing chamber and the slip casting chamber.
Pressurizing chamber can be an oil cylinder, is connected with oil-in 2, oil-out 4, overflow valve 3 and pressure meter 9.Available manual pump or automatic pump pressurize to in-oil cylinder fluid, 1 grouting serous fluid that oil liquid pressure can be passed in its slip casting chamber, top of piston.Pressure meter 9 is used to monitor the size of grouting pressure, and overflow valve 3 is used for overvoltage protection.
Slip casting is provided with exhaust plant in the chamber, the exterior in the inner chamber of described exhaust plant and slip casting chamber.Concrete exhaust plant comprises sealing shroud 5, and sealing shroud is provided with stack 6, the exterior in described stack 6 and slip casting chamber.Stack 6 is provided with control valve 7, can be with gate valve or other valve.
The top in slip casting chamber also is provided with seal cover 8, can open or close sealing, is used to pick and place test specimen, cleans slip casting chamber etc.
The present invention uses the method that above-mentioned fissure rock grouting reinforcement experiment instrument carries out the fissure rock grouting reinforcement experiment, comprising:
Before carry out step 1, at first the sealing shroud 5 of exhaust plant is enclosed within the top of fissure rock test specimen, and will carries out encapsulation process between sealing shroud 5 and the fissure rock test specimen.
Specifically can be with adhesive tape or other method with the sealing joint of sealing shroud 5 with rock sample.Then, rock sample is put in the slip casting chamber of " fissure rock grouting reinforcement experiment instrument ", and connected upward stack 6, afterwards, slurries are added the slip casting chamber, cover the seal cover 8 on top.
Specifically comprise:
Step 21, slowly pressurize, open the control valve 7 of the stack 6 of exhaust plant simultaneously to pressurizing chamber, when having slurries to discharge in the stack 6, closed control valve 7.
When carrying out step 21, at first close the oil-out 4 of pressurizing chamber bottom, oil-in 2 is connected go up force (forcing) pump, and the threshold values of overflow valve 3 is transferred to the maximum grouting pressure value of setting.
Step 22, continuation are to the pressurizing chamber pressurization, and until reaching setting pressure, then the slip casting of fissure rock test specimen finishes.
Afterwards,, open the seal cover 8 on top, slip casting chamber, take out the fissure rock test specimen of slip casting, the fissure rock test specimen of slip casting is carried out maintenance pressurizing chamber oil extraction pressure release.At last, clean the slip casting chamber.
The present invention is divided into slip casting chamber and two parts of pressurizing chamber with the overall structure of experiment instrument, thereby can use the oil pressure pump pressurization, has solved the technical barrier of grouting serous fluid retaining pressure table and overflow valve simultaneously.And utilize the inside and outside pressure differential in slip casting chamber, by setting up exhaust channel, gas in the rock sample crack is discharged to outside, slip casting chamber, and the gas in the time of can avoiding slip casting in the rock sample crack is wrapped in the rock fracture, thereby has realized the abundant slip casting of fissure rock test specimen.
Simple in structure, easy to operate, in the laboratory, can carry out fissure rock grouting reinforcement easily, more easily grouting serous fluid is injected in the fissure rock full and uniformly.
The above; only for the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
