Abstract
The utility model discloses an impervious water capability test device of vehicular bituminous paving, including base, interior steel ring and outer steel ring, the middle part is provided with interior steel ring on the base, the outside is provided with outer steel ring on the base, the inside step -down space that forms of interior steel ring, form the pressure boost space between interior steel ring and the outer steel ring, be provided with the bracing piece between interior steel ring and the outer steel ring, outer steel ring wall connection is provided with the lifter, pressure boost space and step -down space are connected by pipe and compressor respectively. The beneficial effect of the utility model, on -vehicle automatic test has been realized, go behind the test point when the vehicle, the lifter puts down the device, opens the controller of compressor, the test atmospheric pressure intensity in space of bleeding, and then calculate road surface infiltration coefficient, and neither can lead to the fact any pollution to the road surface, still be provided with annular soft rubber circle, increased sealed effect, improved work efficiency.
Description
Technical field
This utility model relates to road surface water permeability resistance can test device, is specifically related to a kind of vehicular
Bituminous paving water permeability resistance can test device.
Background technology
The impervious water test of existing bituminous paving uses the test of standard water creep appearance, by sealing the end
Circle, through certain hydraulic pressure, with water as medium, it is adaptable to measures asphaltic road-mix surface course and is rolled into
The infiltration coefficient of the bitumen mixture specimen of type.Permeability performance and Colophonium mixing with inspection road surface
The mix-design of material.
There is following two problem in current infiltration coefficient test: 1, the process that base seals consumes
Duration, and easy dirty easy pollution road surface, a people to seal, people's timing counting totally two people's operations,
Not only waste of manpower, also reduces efficiency；2, be difficult to find a kind of quickly, environmental protection, bonding
The encapsulant that ability is strong, often occurs that a lot of test sealing effectiveness is the best, and test result can not
Reflection truth.Based on this, test should take into full account the raising of sealing effectiveness and testing efficiency.
Utility model content
For the problems referred to above, this utility model aims to provide the impervious water in a kind of on-board type asphalt road surface
Performance testing device, in the case of having draught head, tests road surface by air pressure level
Dense water energy.
For realizing this technical purpose, scheme of the present utility model is: a kind of on-board type asphalt road surface
Water permeability resistance can test device, including base, interior steel ring and outer rim, and middle part on described base
Being provided with interior steel ring, on described base, outside is provided with outer rim, and described interior steel ring is internally formed
Blood pressure lowering space, forms plenum space between described interior steel ring and outer rim, described interior steel ring is with outer
Being provided with support bar between steel ring, described outer rim outer wall is connected with elevating lever, described increasing
Pressure space and blood pressure lowering space are connected with compressor by conduit respectively.
As preferably, seal between described interior steel ring and outer rim and be provided with annular soft rubber ring.
As preferably, described compressor and elevating lever are also associated with controller.
The beneficial effects of the utility model, it is achieved that vehicle-mounted automatic test；When vehicle travels extremely
After test point, elevating lever puts down device, opens the controller of compressor, test air extraction space
Air pressure level, and then calculate pavement seepage coefficient, not only road pavement will not cause any pollution,
It is additionally provided with annular soft rubber ring, adds sealing effectiveness, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is side-looking structural representation of the present utility model；
Fig. 2 is plan structure schematic diagram of the present utility model.
Detailed description of the invention
With specific embodiment, this utility model is described in further details below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, specific embodiment described in the utility model is a kind of vehicular drip
Blue or green road surface water permeability resistance can test device, including base 1, interior steel ring 2 and outer rim 3, institute
Stating middle part on base 1 and be provided with interior steel ring 2, on described base 1, outside is provided with outer rim 3,
Described interior steel ring 2 is internally formed blood pressure lowering space 4, shape between described interior steel ring 2 and outer rim 3
Become plenum space 5, between described interior steel ring 2 and outer rim 3, be provided with support bar 6, described
Outer rim 3 outer wall is connected with elevating lever 7, described plenum space 5 and 4 points of blood pressure lowering space
It is not connected with compressor 9 by conduit 8.
In order to increase sealing effectiveness, seal between described interior steel ring 2 and outer rim 3 and be provided with ring
Shape soft rubber ring 10.Annular soft rubber ring is tightly bonded on base between interior outer rim, and annular is soft
Rubber ring arranges height draught head, makes rubber ring tightly seal bituminous paving, adds sealing effect
Really, work efficiency is improved.
Controlling compressor for convenience, described compressor 9 and elevating lever 7 are also associated with controller.
When vehicle travels to test point, and elevating lever puts down device, opens the controller of compressor, survey
The air pressure level of examination air extraction space, and then calculate pavement seepage coefficient, and will not road pavement cause
Any pollution, it is achieved that vehicle-mounted automatization.
The above, preferred embodiment the most of the present utility model, not in order to limit this practicality
Novel, every according to technical spirit of the present utility model, above example is made any trickle
Amendment, equivalent and improvement, should be included in the protection domain of technical solutions of the utility model
Within.
