Detection tool for measuring sediment of bored pile

Abstract

The invention provides a detection tool for measuring sediment of a bored pile. The detection tool for measuring the sediment of the bore pile aims to overcome the defects of an existing measuring method for measuring the sediment of the bored pile,. The detection tool for measuring the sediment of the bored pile comprises a measuring rope, a heavy cone block, a flat bottom cover and a probe, wherein the heavy cone block is a hollow cone, a rope ring is arranged inside the heavy cone block, and the rope ring is connected with one end of the measuring rope. The bottom surface of the heavy cone block is provided with a bolt hole, and the bolt hole is communicated with a cavity formed in the inner portion of the heavy cone block. The flat bottom cover is of a structural body shaped like the Chinese character 'tu', and the flat bottom cover is matched with the bolt hole. The probe is a cylinder, and one end of the probe is provided with threads and matched with the bolt hole. The detection tool for measuring the sediment of the bored pile has the advantages of being simple in structure, firm in connection, not prone to damage, long in service circle, capable of accurately measuring the thickness of the sediment of the bored pile and improving the construction quality of the bored pile, simple in detection method, and suitable for being used by small and medium sized projects.

Description

technical field [0001] The invention belongs to the technical field of building measurement, and in particular relates to a detection tool for bored pile sediment measurement. Background technique [0002] With the development of China's railways, higher requirements are put forward for foundation engineering, especially bored pile foundations. Accurately measuring the sediment at the bottom of bored piles is an effective way to ensure and improve the quality of bored piles. At present, the detection methods for the sediment state at the bottom of the bored pile hole include the hammer detection method, the sampling box detection method and the sediment meter detection method. There are deficiencies in the use of the three, as follows: [0003] The measuring hammer detection method needs to be checked frequently before and during use. When there is wear, the number is unclear or the number is displaced, the measuring rope needs to be replaced in time. This method is relat...

Problems solved by technology

However, the disadvantage is that the cost of the instrument is relatively high, calibration is required during use, and construction costs are increased. It is difficult to popularize in small and medium-sized projects. Therefore, there is a lack of low-cost, high-precision detection tools for bored pile sediment measurement on the market.
