Description
Technical field
The present invention relates to roads engineering quality detection field, specifically provides a kind of old pavement drill core equipped with thrustor
Sampler barrel.
Background technology
Important one is exactly to carry out drill core using core drilling method to old road pavement structure in old road detection indices
Sampling, mechanical index experiment is carried out to each layer core sample indoors, to provide necessity when maintaining and design for old road pavement structure
Parameter of structure design.At present according to coring effect and drill core effect, pavement structure basic unit is generally got by drilling.Bottom below basic unit
Basic unit often due to itself mixing material strength characteristics influence, the comprehensive function of durability of asphalt mixture, outside water and traffic load,
It is easily loose that underlayment mixture is down drilled through again, easily blocks drill core cylinder.Mainly there are following several respects to old pavement coring
Meaning：
1st, mainly each layer core sample thickness is measured, differentiates each Rotating fields type of old pavement, understood old pavement and build history, and
Thickness is evaluated, judges the Deflection level of each structural thickness；
2nd, each layer mix type after coring is differentiated, to mixture framework types, gap structure and mixture segregation
Deng
Mixture quality is qualitatively judged；
3rd, at old pavement crack sample, can by core sample observe crack happening part, depth and derive crack occur into
Cause.
4th, to each layer integrality core sample, mechanical index examination is carried out after being processed in laboratory to each layer core sample
Test, old road design parameter is provided for maintenance punishment old pavement.To old road coring, cardinal principle is utilized on hollow drill core cylinder
Drilling bit high-speed rotary, constantly cuts pavement structure, and the pavement structure cylinder essentially identical with cylinder diameter is formed in cylinder
Core sample.Existing drill core equipment is primarily present problems with and shortcoming：
1st, during drill core, constantly to supply water to drill bit, overheat and reduce the resistance in drilling process to prevent drill bit.By
Continuous friction rotation between drill bit and old line structure, constantly has sand shape fines to be filled into core sample and drill core cylinder inner wall, causes portion
Branch face structural core sample is difficult to be taken out from core sample cylinder, can only could be taken out core sample by manually tapping drill core cylinder side wall, is held
Lower core sample is easily caused loosely to destroy, is bothersome, is laborious, and it is less efficient.And more drill down must be deeper, core sample is more difficult to from brill
Taken out in core cylinder.Therefore, when carrying out old road core boring sampling, since industry also wants old road detection drill core depth without mandatory
Ask, general engineering technology personnel's drill core gets pavement structure basic unit by drilling and just stops to bore, if without particular/special requirement, would not continue past
It is lower to bore, so just have no way of learning to understructure mix type and situation, will not be comprehensive to the diagnosis of old road overall condition.
If lower floor's mixture intensity deficiency will loosely influence the road surface entirety performance after maintenance.
2nd, the drill core at pavement structure disease position, since pavement structure inside is more open, is mingled with location of cracks
The fine particles such as soil, fine aggregate.After drill bit stops brill, core sample is easily blocked.Core sample is by soaked, then by tapping, easily
Cause whole core sample to crush, can not judge that road surface structural cracks depth, disease produce type and pavement structure damaged condition.
Therefore, how the core boring sampling cylinder in market is improved, makes it overcome disadvantages mentioned above to have the advantages that again above-mentioned,
It is those skilled in the art's problem urgently to be resolved hurrily.
The content of the invention

One end connects the end of drill core cylinder by trip bolt, and the other end for stretching device that pushes away is pushed away by standing screw connection pushing block
The water hole of multiple axial directions is offered on block, the side of the drill core cylinder is installed with mounting hole in one end of nearly fixed cylinder,
Short tube is provided with mounting hole, one end connection of short tube, which pushes away, stretches device.
As improvement：It is described to push away that to stretch device be the hydraulic cylinder with three-level stretching structure.
Improved as further：The blade is in the end of drill core cylinder in circumferentially disposed.
Improved as further：The material of the blade is cobalt-based diamond.
Improved as further：The material of the pushing block is rubber.
Compared with prior art, the advantage of the invention is that：Device is stretched in pushing away for being set in the present invention, and brill is blocked in core sample
When in core cylinder, device can be stretched by core sample release drill core cylinder, convenient and efficient without tapping core sample cylinder side wall, raising drill core by pushing away
Efficiency, deeper pavement structure thickness, road pavement knot can be drilled through when being somebody's turn to do the old pavement core boring sampling cylinder drill core equipped with thrustor
The overall condition that structure uses can be easy to judge.
