Pile bearing capacity is caused to meet design requirement.Judge the method for stake end defect property and degree often with low strain integrity testing method,
Bore extracting core process, the method that slag is taken in the conventional single drilling of stake end defect cleaning or more drilling clear water circulations.But these methods have one
Foregone conclusion limit, low strain integrity testing method can determine whether a type and extent for end existing defects, but need professional to be understood, drilling
Core sample method can judge the nature and extent of defect by core, but can not accurately check that the degree for the outer defect that drills and defect extend
Direction, it is not thorough etc. that slag cleaning is taken in clear water circulation.Therefore, stake can directly be observed to coring drilling thorough cleaning by finding one kind
The device of the degree of crushing of basement rock, bedrock fracture developmental state and defect cleaning effect under defect situation, stake end is held, for improving
The specific aim and reliability of stake end defect reinforcing, have positive effect.
The content of the invention
The purpose of this utility model is to provide a kind of defect cleaning of stake end, check device, for the broken of stake end group rock
Degree, bedrock fracture developmental state, stake end concrete defect nature and extent or sediment of the hole bottom inspection, make layman
Also it can understand and check an end defect situation, improve the specific aim and reliability of stake end defect reinforcing.
What the purpose of this utility model was realized in：A kind of stake end defect dress watch device, structure include feeler lever,
Spreading often is connected through a screw thread between section feeler lever, the feeler lever of the top is provided with turning handle, and the bottom of bottom feeler lever is provided with work
Head.Wherein, described work head is probe, and probe uses endoscope, is regarded under having, side view and illumination functions, feeler lever are marked with
Scale, so as to accurate recording investigation depth, probe connecting line is passed by feeler lever center, is connected with image display, can be used as inspection
Look into device；
Wherein, described work head or be high-pressure water nozzle, high-pressure water nozzle is cone barrel, and bottom is sprayed water provided with bottom
Mouthful, side is provided with side water jet, and high-pressure water nozzle is connected by the bottom of screw thread and feeler lever, the top of feeler lever and high-pressure rubber pipe
Connection, high-pressure rubber pipe connection water under high pressure, can be used as cleaning plant.
, can be accurate as check device in use, the direction of feeler lever turning handle socket is identical with the side-looking direction popped one's head in
The direction that probe is checked is determined in aperture.
As cleaning plant in use, the direction of side water jet is identical with the direction of turning handle socket on feeler lever,
Can be preferably in the direction of aperture control injection water.
Drilled during use by coring, the check device with endoscope probe is slowly put into drilling, endoscope is visited
Capitiform into image be visually displayed on the display outside hole, probe use Hard link with feeler lever, and inspection depth can be controlled accurately
System, control the turning handle on feeler lever easily can control and record the direction that probe checks.Tripping in cleaning plant after trial inspection, it is right
The depth and direction for checking defect are targetedly cleared up, and the High-Pressure Water of cleaning plant can be injected inside defect, are carried out
Thorough cleaning, tripping in check device again after the completion of cleaning, the effect cleared up by realtime graphic inspection.
The utility model obtain beneficial effect be：
(1) lead to threaded connection between feeler lever, different investigation depths is can adapt to, by the side for recording turning handle
To the extension direction that can determine that defect.
(2) the form and degree for checking defect can be understood by image display, layman is also judged defect feelings
Effect after condition and cleaning.
Can to record the defects of depth and direction carry out specific aim cleaning, have cleaning thoroughly, speed it is fast, with strong points
Advantage, be remarkably improved cleaning effect.
Brief description of the drawings
Fig. 1 is check device structural representation.
Fig. 2 is high-pressure water nozzle structural representation.
The implication that label represents in figure is as follows：
1st, probe 2, feeler lever 3, turning handle socket 4, image display 5, probe connecting line
6th, turning handle 7, connection screw thread 8, bottom water jet 9, side water jet 10, blind bolt.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of stake end flaw detection apparatus, structure include feeler lever 2, formed for more piece, the upper end of feeler lever 2 is set
There is dismountable movable turning handle 6, feeler lever 2 uses the steel pipe manufacturings of Φ 25, often connects spreading by connection screw thread 7 between section feeler lever, visits
