Abstract
The invention relates to the field of a tunnel, in particular to a tunnel joint leakage stoppage test device. The device can detect the effectiveness of a leakage stoppage material for a tunnel joint. The top surface of an upper test die of the device is fixed on an upper supporting seat. The bottom surface of a lower test die of the device is fixed on a lower supporting seat. The upper supporting seat is connected and fixed with the lower supporting seat through at least four connecting screw rods. The upper test die can be jacked by rotating nuts. An inner steel ring and an outer steel ring are arranged between the upper test die and the lower test die. A hole is reserved on the lateral surface of the outer steel ring. A slurry injection pipe is placed in the hole. An exhaust pipe, a water inlet pipe and a slurry outlet pipe are reserved in the upper test die. The tunnel joint leakage stoppage test device has the advantages that the leakage stoppage effectiveness of the leakage stoppage material can be visually judged; meanwhile, for the leakage stoppage material with a certain deformation resistance capability, a deformation resistance quantitative index value is definitely obtained through a test.
Description
Technical field
The present invention relates to tunnel-like, be specifically related to a kind of tunnel seam plugging test device, this device can detect the validity of the lost circulation material that is used for the tunnel seam.
Background technology
The situation that the tunnel seam produces seepage is inevitable, and whether the leak stopping new material and the new technology that adopt can produce a desired effect, and need pass through verification experimental verification.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, the test unit of a kind of tunnel seam lost circulation material is provided, this device is by the force-bearing situation of simulation tunnel seam seepage, thereby adopt corresponding lost circulation material and method, can judge the actual effect of leak stopping at the various lost circulation material straightway testings of tunnel seam seepage, the platform of a test is provided for tunnel seam leak stopping from now on.
The object of the invention realizes being finished by following technical scheme:
A kind of tunnel seam plugging test device, it is characterized in that this device comprises, lower testing mould, wherein the end face of upper testing mould is fixed in upper branching holder, the lower support seat is fixed in the bottom surface of lower testing mould, on, be connected and fixed by at least four connecting screw rods between the lower support seat, connecting screw rod is fixed on the described supporting base by nut, by the rotation nut, can realize the jacking of upper testing mould, on described, be provided with outer rim between the lower testing mould, the inside of outer rim is placed with interior steel ring, outer rim is reserved with hole on the side, is placed with Grouting Pipe in the described hole, in described Grouting Pipe passes to, zone between the outer rim, be reserved with three perforation pipelines in the described upper testing mould, be respectively gas outlet, water inlet pipe and grout outlet.
Steel ring encircled the interior zone that encloses in described gas outlet and water inlet pipe passed to.
Described grout outlet passes to the zone between the inside and outside steel ring.
Between described inside and outside steel ring and upper testing mould, be provided with annular rubber ring.
Described upper and lower die trial is cylindrical shape respectively.
Be connected and fixed by four connecting screw rods between the described upper and lower die trial, described four connecting screw rods evenly distribute.

Fig. 3 is a Facad structure synoptic diagram of the present invention.
Embodiment
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Figure 1-3, label 1-13 represents respectively: Grouting Pipe 1, upper bracket 2, gas outlet 3, water inlet pipe 4, grout outlet 5, upper testing mould 6, screw rod 7, lower testing mould 8, undersetting 9, outer rim 10, interior steel ring 11, screw rod 12, nut 13.
The tunnel seam plugging test device that present embodiment relates to comprises two block concrete right cylinder die trials, it is upper testing mould 6, lower testing mould 8, upper bracket 2 and undersetting 9 all adopt iron plate, on, lower testing mould 6,8 build on the iron plate as upper bracket 2 and undersetting 9, and be fixed in the iron plate basal plane by reinforcing bar, pass through four connecting screw rods 12 between upper bracket 2 and the undersetting 9, nut 13 is connected and fixed, by rotation nut 13, can realize the jacking of upper testing mould 6, be positioned at upper testing mould 6, steel ring 11 in placing between the lower testing mould 8, outer rim 10, be placed with Grouting Pipe 1 on the sidewall of outer rim 10, in upper testing mould 1, reserve three pipelines, it is gas outlet 3, water inlet pipe 4 and grout outlet 5, steel ring 11 interior zone that encloses that encircles in wherein gas outlet 3 and water inlet pipe 4 pass to is in the zone in grout outlet 5 passes between steel ring 11 and the outer rim 10.
The annular rubber ring of default 2mm thickness between interior steel ring 10, outer rim 11 and upper testing mould 6 is in order to reduce the concentration of local stress between steel ring and the upper testing mould.
Present embodiment is when concrete the application, after installing the related test unit of present embodiment, measure the joint gap between the upper and lower die trial, by Grouting Pipe 1 inwardly, slip casting in the zone between the outer rim, there are slurries to overflow until grout outlet 5 pores, stop slip casting, after treating the slurry material stable in properties, apply water pressure to prescribed level by water inlet pipe 4, observe water pressure and can keep stable within a certain period of time, the record experimental phenomena is made preliminary conclusion to the hydraulic pressure resistance performance of the injecting paste material of elastic epoxy slurries.
Whether turn the nut at four screw rod tops in turn, make about upper testing mould 6 slow rising 0.5mm, measure joint gap again, guarantee that new joint gap reaches the requirement of new operating mode, observing has percolating water phenomenon again.
