According to different hole-forming methods, cast-in-place piles can be divided into several categories, such as sinking cast-in-place piles, bored cast-in-place piles and excavated cast-in-place piles. During pile foundation construction, construction workers need to measure the depth of the pile hole to ensure the quality of the pile hole.

[0003] In the prior art, there is a pile hole depth measuring device with announcement number CN212658186U, which includes: a bracket, a stepped shaft horizontally rotatably inserted into the bracket, and a rotating drum fixedly arranged on the circumference of the stepped shaft, a measuring rope is coiled on the circumference of the rotating drum, a detection probe is fixedly arranged on the free end of the measuring rope, a gear ring coaxial with the stepped shaft is fixedly arranged on the side wall of the bracket, a tooth groove of the gear ring is opened on the inner wall of the gear ring, a speed limiter movably engaged with the gear ring is slidingly sleeved on the circumference of the stepped shaft, and an operating handle is fixedly arranged on the end of the stepped shaft on the other side of the bracket; by adding a speed limiter to the stepped shaft, when the speed is too high, the speed limiter engages with the tooth groove on the inner wall of the gear ring under the action of centrifugal force to limit the rotation of the stepped shaft, thereby limiting the maximum lowering speed of the measuring rope.

[0004] However, in the above scheme, due to the presence of mud in the pile hole, when the measuring rope is extended into the pile hole to measure the depth of the pile hole, the detection probe at the free end of the measuring rope needs to reach the bottom of the inner cavity of the pile hole. At this time, part of the measuring rope will be adhered to mud. After the measuring rope is wound up, the mud adhered to the measuring rope will contaminate other clean measuring ropes, thereby increasing the subsequent cleaning work. Utility Model Content

[0005] The utility model aims to provide a foundation pile hole depth detection device, which can clean the mud on the length measuring rope, thereby reducing the subsequent cleaning work.

[0006] To achieve the above-mentioned purpose, a foundation pile hole depth detection device is provided, which includes: a frame; a measuring component, the measuring component includes a rope-taking roller, a measuring rope and a detection probe, the rope-taking roller is rotatably connected to the frame, the measuring rope is wound around the rope-taking roller, one end of the measuring rope is connected to the rope-taking roller, a counterweight is arranged at the other end of the measuring rope, and the detection probe is arranged at the bottom of the counterweight; a cleaning component, the cleaning component includes a water tank, a guide elbow and a cleaning groove, the water tank is located below the rope-taking roller and connected to the frame, the guide elbow and the cleaning groove are both located in the water tank, two guide elbows are provided, the two guide elbows are respectively connected to two opposite side walls of the water tank, the cleaning groove is in an inverted U shape, the cleaning groove is located between the two guide elbows, a screw and a guide rod are provided at the top of the cleaning groove, bristles are provided on the inner side of the cleaning groove, the screw is cooperatively penetrated through the top of the water tank, and the guide rod is slidably penetrated through the top of the water tank.

[0007] The working principle and effect of the above scheme are as follows: the free end of the measuring rope is passed through the top of the water tank and the two guide elbows in sequence, and finally passed out from the top of the water tank. A water inlet pipe for water inlet is arranged on the top of the water tank, and a water outlet pipe for water outlet is arranged at the bottom of the water tank. When the device is used to measure the depth of the pile hole, the device is placed on the top of the pile hole, so that the counterweight block is located above the pile hole, the rope reel is rotated to extend the free end of the measuring rope, and the counterweight block can drive the measuring rope to move toward the bottom of the pile hole. When the counterweight block reaches the bottom of the pile hole, the detection probe can detect the depth of the pile hole. After the measurement is completed, the rope reel is rotated in the opposite direction, and the measuring rope is reeled on the rope reel to shorten the free end of the measuring rope. During this process, the cleaning component works, the water tank is filled with water, and the screw is rotated.
