Description
Technical field
It the utility model is related to range-measurement system, more particularly to a kind of asphalt concrete face slab defect range-measurement system.
Background technology
Bituminous concrete is using pitch as cementing material, is mixed with aggregate (rubble, sand, inserts etc.) by regulation match ratio
The construction material that system, consolidation form, because its barrier performance is good, is commonly used for the earth and rockfill dam, cistern, canal of water conservancy and hydropower industry
The impervious body of road, river course, dyke, shore protection (slope) etc..20th century 50, the sixties, it is big that bituminous concrete has been used for reservoir by Europe
Area antiseepage.In recent years, with the hydroenergy storage station asphalt concrete seepage prevention engineering such as day famine level ground, river bend, Xilongchi, Bao Quan
Build up successively, domestic hydraulic asphalt concrete anti-seepage design and construction technique is developed rapidly.
Asphalt concrete face slab antiseepage form of fracture typically has skeleton symbol and compound point, according to the significance level of engineering, peace
The factors such as full requirement, geological conditions, consider Technological Economy and require to select.Traditional compound cross-section structure typically divides 5 layers, from
On down be respectively confining bed, upper impervious barrier, drainage blanket, lower impervious barrier, leveling glued layer.In view of asphalt concrete seepage prevention layer
Infiltration coefficient itself can reach 1 × below 10-8cm/s, and barrier performance is fine, almost may be considered it is fluid-tight, unless
Destroy, the probability very little that the drainage blanket and lower impervious barrier in compound cross-section play a role, therefore many engineerings have selected province
Fall the structure type of the drainage blanket and lower impervious barrier in compound cross-section, here it is skeleton symbol section.
No matter skeleton symbol or compound antiseepage, the asphalt concrete face slab to put into operation is it sometimes appear that irregular bulge and split
Phenomena such as seam.Further deterioration will result in board cracking for bulge, increase panel seepage possibility, once whole antiseepage section meets with
To destruction, a large amount of infiltrations can flow to bottom storehouse, if basic rock stratum has the soft layer for meeting water sensitive, infiltration long term may shadow
Rock mass stability is rung, causes serious consequence.The conventional method of detection asphalt concrete face slab defect is core sampling drilling at present, the party
Method exist efficiency it is low, it is representative it is poor, unavoidably destroy the shortcomings that former impervious body globality.Therefore it is badly in need of a kind of quick nondestructive
Detection method, can accomplish for occurred bulge, crack can Quantitative evaluation, draw depth of defect, size, if pass through
Wear antiseepage section；Comprehensive physical examination is done for the intact region in surface, where searching hidden danger, distinguishes defect type.
In order to detect drawbacks described above, detected using asphalt concrete face slab range-measurement system, existing bituminous concrete
The ranging unit of panel range-measurement system is provided separately with antenna.Current working method is that antenna is placed between measuring wheel, day
Line directly contacts with testee.Because ranging size of wheel is small, the road clearance is just small, and running into barrier will tilt, antenna
Can be with tilting.Antenna is not parallel with asphalt concrete face slab to be measured, and its precision measured can not just ensure.Therefore it is badly in need of a kind of
New range-measurement system has solved the above problems.
