The anchor cable support is a construction process of drilling holes on a side slope and connecting rock masses around a foundation pit through anchor cables, concrete and the like to form a firm whole, the anchor cable drilling holes comprise a free section and an anchoring section, and the aperture of the anchoring section is larger than that of the free section and is formed by expanding holes of high-pressure water columns. The anchoring section is an important part of the anchor cable support, and the aperture and the hole depth of the anchoring section directly influence the overall effect of the anchor cable support. The internal environment of the anchoring section is complex, mud and gravels are more, and the hole wall collapse, the drill sticking and the like can seriously affect the drilling hole forming rate in the drilling process. The actual aperture of the diameter-variable area of the anchoring section cannot be effectively detected by the conventional measuring methods such as a vernier caliper, a standard rod, a two-lobe detector and the like, so that secondary reaming is not timely and in place, and finally the depth and the diameter of the anchoring section of the drilled hole do not reach the standard. If the aperture of the reducer section is smaller than the design value, the anchor cable support after grouting cannot reach the designed anchoring strength, and huge potential safety hazards are easily generated. Aiming at the situation, the invention provides a device for detecting the inner diameter size of the anchor cable support reducing drill hole by ultrasonic waves, and discusses the principle and the operation method of the device. Practice shows that the novel technology can be used for quickly and accurately detecting the size of the drilled hole, improving the hole forming rate of the drilled hole and ensuring the slope support quality.

The utility model discloses the solution is as follows:

the ultrasonic detection instrument consists of a handheld imager and a sound wave probe, wherein the handheld imager comprises a main controller, a sub-controller and an ASP signal processor. The acoustic wave probe includes an ultrasonic wave transmitting unit and a receiving unit. Inside sound wave probe accessible connecting hole depth scale line put into the drilling, handheld imager can show drilling inner space data, and both carry out wired connection through hole depth scale line. When the drill hole is deep, other extension lines can be replaced, and the sound wave probe is wirelessly connected with the handheld imager. The main controller can control the whole system to be turned on or off, and can also control the sound wave emission frequency. The sub-controller adjusts the working frequency of the acoustic emission unit to adapt to drilling under different geological conditions. Four high-linearity CHIRP sound wave emitters are arranged in the ultrasonic wave emitting unit, double-frequency sound waves can be emitted to different directions at the same time, and the scanning imaging effect is more accurate and faster than single-frequency sound wave measurement. The ultrasonic receiving unit receives the sound wave signals reflected by the hole wall, converts the sound wave signals into wireless pulses and feeds the wireless pulses back to the signal processor. The ASP signal processor can rapidly calculate the internal dimension of the drill hole through the sound wave reflection time, integrates the reflection signals in different directions to generate the ultrasonic image of the drill hole, and more intuitively knows the internal condition of the drill hole. If the drilling depth is larger, the speed of the probe passing through the drilling can be controlled through the hole depth scale line, so that more accurate measurement data can be obtained.

Compared with the prior art, the utility model has the advantages of easy operation, measurement accuracy is high, the universality is strong, can have enough to meet the need the use. The distance measurement and the imaging have two functions, and the internal sizes of the variable diameter sections at multiple positions can be detected by one-time measurement. The waterproof and dustproof characteristics can solve the problem that the conventional detection instrument cannot measure or cannot measure accurately when meeting water, and the applicability is strong. The wireless connection can ensure that the depth of the detection hole is not limited, and the detection depth is larger than that of a traditional standard rod and a two-petal type detector. Aiming at different drilling geological conditions, the detection precision can be improved only by adjusting the sound wave emission frequency of the probe in the drilling hole. The utility model discloses a hole detection demand under various construction conditions can be satisfied basically.
