Description

Technical Field

[0001] The utility model belongs to the technical field of measuring devices, in particular to a hammer hook used for measuring the distance between a guide tube and a pile hole bottom after installation. Background Art

[0002] At present, the mainstream single pile construction process in China is drilling → primary hole cleaning → lowering the steel cage → secondary hole cleaning → pouring concrete. During the secondary hole cleaning process, the conduit needs to be lowered into the hole. According to actual construction cases, the lower end of the conduit needs to be 30-50cm away from the bottom of the hole according to different pile diameter requirements to ensure that the sediment is cleaned up quickly and efficiently. If the distance is too large, the sediment cannot be sucked into the conduit; if the distance is too small, the cleaning area will be reduced, and the position of the conduit needs to be moved multiple times, thereby increasing the workload. However, in the actual construction process, the distance between the lower end of the conduit and the bottom of the hole is often determined by subtracting the hole depth from the theoretical length of the conduit. Because the depth of the hole is often deep, the conduits need to be connected to each other. The conduits are connected to each other by threaded connection. In addition, the weight of the conduit itself is large, which causes gaps between the conduits that are threaded together and generates variables, thereby ignoring the increase in deformation due to the weight of the conduit, resulting in the actual distance between the lower end of the conduit and the bottom of the hole being less than the required distance, resulting in the inability to quickly clean up the sediment at the bottom of the hole. Utility Model Content
