Abstract

The utility model relates to the rigid protection face device for Shield Tunneling face seepage erosion model test, comprise rigid protection face, described rigid protection face is provided with one deck pervious bed, and drainage channel is provided with on rigid protection face, this drainage channel connects by drainpipe the capsule that catchments, and described drainpipe is provided with solenoid valve.Compared with prior art, in the utility model process of the test, testing crew passes through Controlling solenoid valve switch to realize the control to solenoid valve, reach and control the object whether tunnel support face is in hull-borne, thus realize the process of simulation tunnel front soil body unstability under seepage state.

Description

For the rigid protection face device of Shield Tunneling face seepage erosion model test
Technical field
The utility model relates to the mask device for unstable failure under the seepage state of Geotechnical Engineering analysis of model tests tunnel excavation face, especially can simulate the generation of seepage flow.
Background technology
At present, the known tunnel support face for analyzing excavation face stability has two kinds, and a kind of is the rigid protection face manufactured with alloy, and another kind is the flexible support face made of rubber bag tank.These two kinds of support forms can in model test the destructive process of simulation tunnel unstability, but due to rigid protection face or flexible support face be all fluid-tight, the process of square sediment failure in face of tunnel excavation under und rained condition can only be simulated.Cause cannot considering the impact of seepage flow on sediment failure during model test, cause the limitation of model test situation.
Summary of the invention
The purpose of this utility model is exactly provide a kind of tunnel excavation face stability analytical model test that can not only be used for simulating under not drainage situation to overcome defect that above-mentioned prior art exists, and can control to prop up mask whether draining simulate the rigid protection face device for Shield Tunneling face seepage erosion model test that the tunnel excavation face stability analytical model under drainage situation tests.
The purpose of this utility model can be achieved through the following technical solutions: for the rigid protection face device of Shield Tunneling face seepage erosion model test, comprise rigid protection face, it is characterized in that, described rigid protection face is provided with one deck pervious bed, and drainage channel is provided with on rigid protection face, this drainage channel connects by drainpipe the capsule that catchments, and described drainpipe is provided with solenoid valve.By the open and close of solenoid control drainage channel, prop up mask when drainage channel is opened and be in seepage state, prop up mask when drainage channel is closed and be in not hull-borne.Due to model casing limited space during test, the moisture that the capsule that catchments is located to the row of collection after drainage channel, to be connect.
Described pervious bed is embedded in rigid protection face.
Described pervious bed is fixed on rigid protection face by coupling bolt, and is provided with rubber weather strip between pervious bed and rigid protection face.
Described rubber weather strip is arranged on the edge that pervious bed contacts with rigid protection face, and forms the space of draining in centre.
Described pervious bed is permeable stone.
Described drainage channel is arranged on bottom rigid protection face.
Compared with prior art, the utility model not only may be used for analyzing the model test of tunnel excavation face stability under non-seepage state, also may be used for considering the model test that tunnel excavation face under seepage flow and the acting in conjunction of soil body severe is stable.And structure is simple, be highly susceptible to processing.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment 1
As shown in Figure 1, for the rigid protection face device of Shield Tunneling face seepage erosion model test, comprise rigid protection face 1, described rigid protection face 1 is provided with one deck pervious bed, and pervious bed is permeable stone 2, and permeable stone 2 is embedded in rigid protection face 1.And drainage channel is provided with on rigid protection face 1, this drainage channel connects by drainpipe 3 capsule 5 that catchments, and described drainpipe 3 is provided with solenoid valve 4.By solenoid control switch 6 connected electromagnetic valve 4, control the open and close of drainage channel, when drainage channel is opened, rigid protection face 1 is in seepage state, and when drainage channel is closed, rigid protection face 1 is in not hull-borne.Due to model casing limited space during test, the moisture that the capsule that catchments is located to the row of collection after drainage channel, to be connect.The diameter of usual drainpipe 3 will be determined according to discharge result of calculation, preferably gets the 1-2 of flow doubly.
Embodiment 2
As shown in figs. 2 to 4, for the rigid protection face device of Shield Tunneling face seepage erosion model test, comprise rigid protection face 1, described rigid protection face 1 is provided with one deck pervious bed, pervious bed is permeable stone 2, permeable stone 2 is fixed on (rigid protection face 1 is as shown in Figure 3 provided with bolt hole 11 for being connected with coupling bolt 8) on rigid protection face 1 by coupling bolt 8, and is provided with rubber weather strip 7 between permeable stone 2 and rigid protection face 1.Described rubber weather strip 7 is arranged on the edge that permeable stone 2 contacts with rigid protection face 1, and forms the space 9 of draining in centre.Be provided with drainage channel (drainpipe connecting hole 10 as shown in Figure 3) on bottom rigid protection face 1, this drainage channel connects by drainpipe 3 capsule that catchments, and described drainpipe 3 is provided with solenoid valve 4.The open and close of drainage channel are controlled by solenoid valve 4, when solenoid control switch 6 is opened, now drainpipe 3 draining, and then the draining controlling rigid protection face 1.When solenoid control switch 6 cuts out, now drainpipe 3 not draining, and then control rigid protection face 1 not draining.Meanwhile, control the movement in rigid protection face 1 by control system, thus on the test of tunnel excavation face soil stabilization impact under the Study of the Realization water and soil couple state.
