Description

Technical Field

[0001] The utility model belongs to the technical field of pile foundation sediment thickness detection, and particularly relates to a device for detecting the sediment thickness at the bottom of a pile foundation. Background Technique

[0002] Pile foundation sediment refers to the sediment left during the drilling and hole cleaning processes that is not carried away by the circulating mud due to various factors, generally being coarser particles. These sediments may exist at the bottom of the pile hole and have an adverse impact on the quality and stability of the pile foundation.

[0003] Currently, the Chinese utility model with the publication number CN220690066U discloses a device for detecting the sediment thickness at the bottom of a pile foundation, including a frame and a detection probe, and further including: a retracting and releasing mechanism for driving the detection probe to lift and lower; by rotating the support member, the U-shaped seat and the first and second guide wheels thereon can be angularly offset, and through the guiding of the connecting line by the second guide wheel, the detection probe can always be above the pile foundation opening, eliminating the need for workers to always hold the connecting line by hand to keep the detection probe above the pile foundation opening, reducing labor and detection time, greatly improving the detection efficiency of the sediment thickness of the pile foundation; and being able to improve the safety factor with good use effects.

[0004] However, the existing devices for detecting the sediment thickness at the bottom of a pile foundation are not effectively convenient for quickly detecting the sediment thickness, and at the same time, they are not effectively convenient for adjusting and installing according to the diameter of the pile foundation. To solve the above problems, we provide a device for detecting the sediment thickness at the bottom of a pile foundation. Content of the Utility Model

A measuring rope is wound on the surface of the winding wheel. One end of the measuring rope is bolted with a vertical rod. A bottom plate is bolted at the bottom of the vertical rod. A through hole is opened inside the bottom plate. A support pipe is bolted at the bottom of the base. Support rods are slidably sleeved at both ends of the support pipe. A ratchet wheel is bolted on the surface of the rotating shaft. A pawl is rotatably connected to one side of the side plate. One end of the pawl is engaged with the ratchet wheel.

[0007] Adopting the above technical solution: The user can place the device on the top of the pile foundation, and then pull the handle to drive the pawl to disengage from the inside of the ratchet, so that the bottom plate falls into the pile foundation. By setting through holes, it can effectively make the bottom plate fall quickly. When the bottom plate lands on the top of the sediment, subtracting the length measured by the measuring rope from the depth of the pile foundation is the thickness of the sediment, so that it can effectively facilitate the rapid detection of the sediment thickness. The user can rotate the crank to drive the winding wheel to wind up the measuring rope. At the same time, the elastic plate drives the pawl to limit the ratchet, and it is convenient to automatically lock the winding wheel. Then pull the support block to drive the support rod to slide inside the support tube, and then turn the limit bolt to limit the support rod through the limit sleeve, so that it can effectively facilitate the adjustment and installation according to the diameter of the pile foundation.

[0008] The present utility model is further arranged such that the other end of the elastic plate is bolted with a fixing frame, and one side of the fixing frame is bolted with a side plate.

[0015] Adopting the above technical solution: By setting the limit bolt, it can effectively limit the support rod.

[0016] The present utility model is further arranged such that a crank is bolted at one end of the rotating shaft, and scale lines are printed on the surface of the measuring rope.

[0017] Adopting the above technical solution: By setting the scale lines, it can effectively facilitate the viewing of the used length of the measuring rope.

[0018] In summary, the present utility model has the following beneficial effects:

[0019] 1. The user can place the device on the top of the pile foundation, and then pull the handle to drive the pawl to disengage from the inside of the ratchet wheel, so that the bottom plate falls into the pile foundation. By setting through holes, the rapid falling of the bottom plate can be effectively achieved. When the bottom plate lands on the top of the sediment, subtracting the length measured by the measuring rope from the depth of the pile foundation is the sediment thickness, thus enabling the rapid detection of the sediment thickness effectively and conveniently.
