A simple filling pile hole depth measuring device and implementation method

Abstract

The invention discloses a simple pouring pile hole depth measuring device and an implementation method, belonging to the construction technology of pouring pile holes. It includes a positioning system and a measuring system. The positioning system is arranged inside the cast-in-place pile hole. The measuring system includes a fixed frame, a rotating shaft, a winding wheel, a measuring line with a scale, and a wire hammer. The fixed frame is fixedly connected to the positioning system and fixed The frame is equipped with a guide frame for the fixed point of the measuring line to move up and down. The winding wheel is connected to the fixed frame through the rotating shaft. The winding wheel is connected to the wire hammer through the guide frame, and the weighing unit is used to judge that the wire hammer has touched the bottom and read the readings on the measuring line to measure the depth of the cast-in-place pile hole. The up and down movement of the hammer always keeps the vertical movement at the same point, which effectively guarantees its measurement accuracy and construction quality, and can also realize accurate measurement without stopping the machine, effectively avoiding damage to mechanical equipment.

Description

technical field [0001] The invention belongs to the construction technology of cast-in-situ pile holes, and in particular relates to a simple and simple cast-in-situ pile hole depth measuring device and an implementation method. Background technique [0002] Cast-in-situ piles have the advantages of no vibration, no soil extrusion, low noise, and are suitable for use in densely built urban areas during construction, and are widely used in construction. [0003] During the construction of bored piles, various quality indicators such as hole depth should be inspected and accepted. The hole depth inspection can be inspected by measuring rope or measuring the length of drill pipe. Use the method of measuring the length of the drill pipe to check the depth of the hole. If the measurement is not stopped, it will easily cause mechanical damage. If the measurement is stopped, the working efficiency of the drilling rig will be reduced. Using the measurement rope requires personnel to...

AI Technical Summary

Problems solved by technology

Use the method of measuring the length of the drill pipe to check the depth of the hole. If the measurement is not stopped, it will easily cause mechanical injury accidents. If the measurement is stopped, the working efficiency of the drilling rig will be reduced. Using the measurement rope requires personnel to stand in the hole to measure it. During the measurement process, it will be in a non-vertical state downwards, which will affect its measurement accuracy and cause deviations, reducing its construction quality
