Detection method and device.
Background technology
In engineering with civil buildings, in order to detect the quality of engineering foundation pile and provide acceptance basis, it is often necessary to detection
Sediment of the hole bottom thickness；Now commonly use detection method and mainly use core drilling method, edit and record by core boring sampling and to it, measure knockout
Sediment thickness in sample, sediment of the hole bottom is mainly made up of earth loose during pore-forming or hole pile lining slough, palpus in boring procedure
Adding water to hole, sediment is easily washed away and can not obtain core sample, and to apply drilling rod certain in drilling process
Pressure, the sediment thickness measured by core sample is differed greatly compared with actual.Therefore, prior art is still not ideal enough.
Content of the invention

3), data process：Data are processed, obtains the full cylinder observation imaging plane unfolded image of borehole wall；
4), video recording picture is identified：Identify concrete, sediment, the proterties of supporting course in picture, it is determined that pile bottom sediment
Position, thickness and composition.
The method uses the detection device of such a engineering foundation pile sediment thickness to realize, it includes being drilled with on foundation pile
Hole, is provided with a support tripod on the aperture in hole, one pulley of the underhung of support tripod, the ground other in aperture
On a borehole imaging instrument main frame and winch are set, connect borehole imaging instrument main frame and winch by cable, and by under pulley
Fall in hole, be provided with in a hole probe in the bottom of cable.
It is a kind of home position testing method that the present invention uses boring panoramic imagery method to carry out video recording to hole wall, passes through borehole wall
Tunneling boring planar development image, reflects borehole wall information intuitive, clearly, with visual method be directly acquainted with sediment thickness and
Composition；The method has good economy, and testing result is simple and clear, Detection results good, applicability is strong.
