Description
Technical field
The present invention relates to a kind of mud film sample ring cutting devices more particularly to city underground, the tunnel across Jiang Yuehai etc. to use mud
Mud geological adaptability proportioning test in balanced type shield, slurry penetration stratum laboratory test slurry penetration stratum film forming cut
Take device.
Background technique
Since slurry-water balance type shield can effectively control stratum settlement amount, it is widely used to the city of complicated geological environment
During the engineerings such as city's subway tunnel, the tunnel across Jiang Yuehai are built.Slurry-water balance type shield is balanced using the mud pressure in muddy water storehouse
The Water And Earth Pressures of excavation face maintain excavation face to stablize.Therefore, the geological adaptability of mud and muddy water storehouse pressure are arranged heavy to closing
It wants.
Mud is to evaluate the important indicator of mud geological adaptability to the Penetration Signature on stratum, and mud quality of forming film directly closes
It is that could maintain constant pressure to muddy water storehouse, guarantees the stabilization of excavation face in shield tunneling process and stopping process.So shield
Structure construction period should carry out the work of mud optimal proportion.Traditional simulated mud only considers the specific gravity of mud itself, viscosity, filter
The parameters such as vector seldom carry out the test of slurry penetration stratum.However, only can't sufficiently reflect by the physical property of mud itself
Its geological adaptability, thus carry out mud stratum permeability characteristic test be very it is necessary to.
Currently, only several units for part slurry shield engineering carried out slurry penetration stratum test, to experiment tie
The description of fruit is only limitted to mud film outward appearance and shape, does not test the mechanical attribute of mud film, can not pass through the power of mud film
Learn attribute evaluation quality of forming film.Therefore, it is most important effectively to obtain the mud film that slurry penetration stratum is formed, is measurement mud membrane forces
The premise of attribute.
Summary of the invention
For slurry balance shield mud geological adaptability proportion in lack slurry penetration quality of forming film Experimental Study On Mechanical Properties
The problem of, the present invention provides a kind of indoor slurry penetration stratum into the mud film sample ring cutting device of film test, has to mud film
It disturbs small, mud film to cut convenience, cut the advantages that mud film thickness is variable, provides and obtain for subsequent development mud film Experimental Study On Mechanical Properties
Take the short-cut method of mud film sample.
To achieve the above object, the technical solution used in the present invention is: a kind of mud film sample ring cutting device, it includes examination
It tests cutting ring, spiral-lock and cuts native cutting ring and sliding sleeve mounted in the push plate cut in native cutting ring inner cavity test cutting ring lower end；The examination
It tests cutting ring and cuts native cutting ring by being provided with the inside and outside seam allowance spiral-lock of ramp type for cutting native cutting ring and test cutting ring end respectively one
It rises；Scale value is provided in the test cutting ring, the lower end edge for cutting native cutting ring is cutting edge formula structure.
Further, the present invention in the test cutting ring and cuts and is also buckled with several standard cutting rings, institute between native cutting ring
The upper and lower end for stating standard cutting ring offers the inside and outside seam allowance of ramp type respectively.
Further, the present invention is in the test cutting ring, standard cutting ring and to cut native cutting ring outer at fastening between each other
Multiple tight fixed bolts for being fixedly connected are uniformly arranged on disc.
Further, the present invention is in the test cutting ring, standard cutting ring and to cut native cutting ring outer at fastening between each other
Several T-type positioning pins used for positioning have been uniformly arranged on disc.
Further, the bottom surface of push plate of the present invention is provided with handle, and uniformly offers in the plate face of push plate more
A air hole.
The method and step for cutting mud film sample using above-mentioned mud film sample ring cutting device is as follows:
A, it according to slurry penetration formation thickness, determines cutting ring combination, such as tests the native cutting ring combination of cutting ring+cut or test cutting ring
+ standard cutting ring+cuts native cutting ring combination, fixes tight fixed bolt using T shape positioning pin；
B, after selection mud cuts position, the ring cutting device down-bite jaw that will be combined is vertical to be pressed into mud film, until reaching examination
It is steady when cutting ring is pressed into until testing the graduation mark determined in cutting ring, firmly unanimously；
C, the cutting ring that will be pressed into mud film tilts an angle, takes out the ring cutting device for having mud film sample；
D, mud film sample all as needed, is released into ring cutting device with push plate, or withstands on mud film sample bottom, by standard ring
It knife and cuts native cutting ring and exits a distance, with native knife is cut or fret saw scabbles the extra soil body of test cutting ring lower end, testing
It can be obtained that above and below is smooth in cutting ring, and the mud film sample that thickness equidimension Pass Test requires.
Specifically: mud film sample ring cutting device of the invention includes three kinds of cutting rings: test cutting ring, cuts soil at standard cutting ring
Cutting ring, three kinds of cutting rings pass through inclined-plane fixing structure, tight fixed bolt, the combination connection of T shape positioning pin.Test cutting ring is for obtaining and depositing
Certain thickness mud film is stored up, and mud film Experimental Study On Mechanical Properties can be carried out together with ring cutting sample.Standard cutting ring is dimensional standard part,
Soil thickness is cut for increasing.Cutting native cutting ring one end is cutting edge, tests the mud film to be formed for cutting slurry penetration.It is seeped according to mud
Saturating formation thickness can be used test cutting ring+cut native cutting ring combination, test cutting ring+standard cutting ring+can also be used and cut native cutting ring
Combination passes through the fixed each cutting ring of the tight fixed bolt being arranged on T shape positioning pin.After cutting soil, tight fixed bolt is unclamped, is utilized
Push plate will cut the release of mud film sample, or withstand on ring cutting sample bottom, by standard cutting ring and cut native cutting ring and exit a distance,
With cutting native knife or fret saw scabbles the test extra soil body in cutting ring end.Push plate circle end face diameter is slightly smaller than cutting ring internal diameter, and is distributed
There is aperture, guarantees the discharge of formation pore water and air.
The beneficial effects of the present invention are: mud film sample ring cutting device of the present invention is capable of the mud film examination of quick obtaining different-thickness
Sample, and it is smaller to the disturbance of mud film sample.Meanwhile sample will be cut and be retained in test cutting ring, achievable mud film shearing strength
The Experimental Study On Mechanical Properties such as test, mud film permeability test can pass through the mechanical property parameter evaluation mud quality of forming film of mud film.
Detailed description of the invention
Fig. 1 is the structure principle chart of mud film sample ring cutting device of the present invention.
Fig. 2 is the enlarged drawing of inclined-plane fixing structure in Fig. 1.
Specific embodiment
With reference to the accompanying drawing with apparatus structure introduction, application method of the invention is described further.
