Description
Technical field
The invention belongs to subgrade and pavement and detect and the maintenance technology, relate in particular to roadbed defect identification and high polymer grouting rapid reinforcement technology.
Background technology
Current, the high-grade highway construction of China is in the stage of developing rapidly.Roadbed is as the important component part of pavement structure, is not only and realizes that vehicle can provide basic condition in travels down, and be the supporting structure thing on road surface, to the usability on whole road surface with play crucial effects serviceable life.But many road surfaces are because the roadbed quality problems, there are phenomenons such as compactness deficiency or cavity, road surface, the back early damage that is open to traffic will soon occur, as depression, cracking etc., build up the needs that just can not adapt to vehicle pass-through soon, the maintenance project amount is increasing, and is also more and more higher to the requirement of maintenance technology.Therefore, roadbed is detected for the concrete development environment of China's road construction and objective situation and the maintenance technology has proposed the stern reality requirement, need actively develop the exploitation and the application that detect with the maintenance new technology.
Accurately the evaluation roadbed defect is the basis of it being carried out maintenance.Because the highway in China construction is started late, it is still relative backward with means and reparation maintenance technology to estimate roadbed performance detection equipment.Also mainly depend on the method for artificial experience such as the existing roadbed quality testing of China, flexure detects the Beckman beam that mainly also adopts the invention fifties, the artificial means that this traditional bowing bent over, carried on one's shoulders or with both hands, and not only efficient is low, and representative poor, security is also poor; On the other hand, in the road network maintenance processes,, cause the irrationality of maintenance scheme and maintenance fund allocation owing to can not make the evaluation of comprehensive and reasonable to the usability of road network; Prior one side simultaneously since lack efficient, fast, roadbed that permanance is strong repairs the maintenance new technology, make for existing because excavation is mainly adopted in the reparation of roadbed quality problems, again the method for surfacing again behind the compacted subgrade.This method is obviously time-consuming and will spend a large amount of funds, and the social influence that causes is very huge.More domestic units also study the method that adopts slip casting and handle the roadbed problem, it mainly is cement mud jacking method, though it is short that this method duration goes up relatively, but exist the mud jacking hole bigger, road pavement has that certain infringement, mud jacking pressure are not easy to control, slurries mobile bad, need deficiencies such as certain curing time, endurance quality be bad.
As can be seen, existing traditional roadbed method of evaluating performance and reparation maintenance technology can not satisfy busy day by day traffic needs, the development of the current highway construction of this situation and China is far from suitable, and needs quick, easy, effective roadbed defect Non-Destructive Testing evaluation of development and maintenance new technology badly for this reason.
Along with developing rapidly of China's expressway construction, be that the Dynamic Non-Destruction Measurement of representative is subjected to increasingly extensive attention with Falling Weight Deflectometer and ground penetrating radar.Falling Weight Deflectometer has been simulated the dynamic action of actual traffic load road pavement preferably, and it is fast to test the speed, and the precision height at home and abroad is widely used.Ground penetrating radar has obvious superiority aspect the fast detecting pavement structure layer thickness, and coming to nothing on the road surface demonstrates wide development and application prospect aspect identification, basic unit and roadbed defect identification, compactness and the water cut express-analysis.Strategic highway project (SHRP) the row monographic study Falling Weight Deflectometer and the ground penetrating radar application technology of U.S.'s enforcement in 1988 have obtained more rich achievement.Domestic many Falling Weight Deflectometer and the ground penetrating radar detection system introduced in recent years.But, do not play one's part to the full as yet owing to lack supporting practical technique.Particularly Falling Weight Deflectometer and ground penetrating radar are applied to the detection evaluation of the performance condition of roadbed, still are in blank field at present at home.
Falling Weight Deflectometer utilizes hydraulic system to promote a weight, discharges the back road pavement and applies impulsive load, uses high-precision sensor and gathers road surface multiple spot flexure information, provides the foundation for further analyzing pavement structure stiffness layer and load-bearing capacity.Ground penetrating radar is by emitting antenna road pavement emission frequency electromagnetic waves, and electromagnetic wave reflects when running into the structural sheet interface, and reflected signal is by the receiving antenna collection, thereby provides the foundation for analysis road surface structare layer dielectric property and thickness, the situation of coming to nothing etc.
Research and development about high polymer grouting rapid servicing technology start to walk early to have obtained major progress the nineties, and be used widely in countries such as the U.S., Canada, Australia in the world.Can reach 20 times because high polymer grouting material own vol expands, therefore, it not exclusively relies on mud jacking pressure and fills the district of coming to nothing, and its expansion character has ensured its compaction to roadbed.In addition, superpolymer mud jacking technologic material consumption less (have only cement injection volume 25%), lack (only needing several hrs) man-hour, the mud jacking aperture has only 1.6cm, lightweight (weight be equivalent to consubstantiality ponding mud, cement concrete 5%), the weak combination that intersects does not take place in material during slip casting, and the material after powerful adhesion has been avoided handling is because of caving in that immersion causes.These characteristics have obvious superiority with respect to cement mud jacking method.Therefore, high polymer grouting rapid servicing technology has obtained a large amount of application in the repair process on road foundation, road surface in the world, has obtained huge economic and social benefits.But the subject matter that exists is that the high polymer grouting construction technology is based upon on the experiential basis always, is separated with advanced detection techniques such as Falling Weight Deflectometer, ground penetrating radar.Therefore, though the high polymer material permanance reached more than 10 years, the slip casting maintenance effect can not be guaranteed.
The core of high polymer grouting rapid servicing technology is high polymer material and injection technique thereof.Wherein the superficial part injection technique is mainly used in the come to nothing reparation and the lifting of concrete slab, and the deep injection technique is mainly used in the reinforcing of roadbed and infrastructure ground.
The high polymer grouting technology is keeped in repair sub-surface and reinforcing road bed by injection bi-component superpolymer liquid.The superpolymer liquid of injection forms solid by chemical reaction, and volume expands rapidly simultaneously, thereby fills coming to nothing in the pavement structure, and medium applies controlled pressure towards periphery.
