Concrete cast-in-place pile bottom sediment thickness detection device and method

Abstract

The invention discloses a concrete cast-in-place pile bottom sediment thickness detection device and method, and belongs to the technical field of cast-in-place pile construction quality detection. The concrete cast-in-place pile bottom sediment thickness detection device comprises a fixing frame, wherein a fixing plate is connected to the inner wall of the middle of the fixing frame, a transmission assembly is rotationally connected to the top face of the middle of the fixing plate in a penetrating mode, a motor A is fixedly arranged on the top face of the middle of the fixing plate, a rotating plate is arranged on the lower side of the fixing plate, a slag removal assembly is connected to the top face of the rotating plate, a measuring line is wound on the outer wall of a winding rod, a worm is arranged on the rear wall of the left end of the fixing frame in a penetrating mode, and a winding assembly is connected to the inner wall of the front side of the left end of the fixing frame. According to the concrete cast-in-place pile bottom sediment thickness detection device and method, the slag removal assembly is arranged, a dust suction pipe and a dust collector are utilized so that sediment can be cleaned in time when the sediment thickness is too large, then the transmission assembly is utilized so that the dust suction pipe can be cleaned in a large range, cleaning of one position is avoided, the cleaning effect is greatly improved, and therefore the device is diversified in function and higher in practicability.

Description

technical field [0001] The invention relates to the technical field of construction quality detection of cast-in-place piles, and more specifically relates to a device and method for detecting the thickness of sediment at the bottom of concrete cast-in-place piles. Background technique [0002] Sediment refers to the sediment left by the sedimentation or collapse of the hole during drilling and hole cleaning, which is not taken away by the circulating mud. Generally, it is a relatively coarse particle, and the thickness of the sediment is the layer height of this layer of sediment. However, some people think that the thickness of the sediment is the difference between the depth of the hole measured by Yiqing and the depth of the hole measured after the conduit is lowered. The prior art CN110905011A discloses a method for detecting the thickness of the sediment at the bottom of the concrete pouring foundation pile. The embedded steel pipes, rollers and measuring ropes are se...

Problems solved by technology

But this device also has the disadvantage that the device is simple in structure and has a single function, and can only measure. When the thickness of the sediment is too thick and unqualified, it is not convenient to clean the thickness of the sediment. Because the device is not convenient for uniform winding of the measuring rope when the side rope is being rolled up, the measuring rope is easy to be rolled up repeatedly at one position during winding, resulting in uneven winding, and the device is not convenient Fix the shaft and affect the detection. At the same time, the existing patented technology CN201922095894 involves a similar problem in the detection device for the thickness of the sediment at the bottom of the concrete pouring foundation pile pile. The rope body in the cast-in-place pile hole moves left and right before being stored in the roller to achieve uniform storage, but this operation is only applicable to the rising process of the rope body after the inspection is completed, and it is not necessary during the falling process of the rope body in the early stage of detection It makes the rope body move left and right, which wastes the driving power. In addition, during the left and right guidance process, the mass hammer at the bottom of the rope body will shake left and right, and will accidentally touch the inner wall of the pile hole, causing more slag to fall, while the existing left and right movement The guiding mechanisms are all guided by lifting and lowering double strokes, which inevitably have the above-mentioned defects. In view of this, we propose a device and method for detecting the thickness of sediment at the bottom of concrete pouring piles
