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

Embodiment 1

[0031] Such as Figure 1 to Figure 4 As shown, a simple hole depth measurement device for cast-in-place piles includes a positioning system and a measuring system. The positioning system is set inside the hole of the cast-in-place pile. The measuring system includes a fixed frame 1, a rotating shaft 2, a winding wheel 3, and a measuring line with a scale. 4, the wire hammer 5, the fixed frame 1 is fixedly connected on the positioning system and the fixed frame 1 is provided with a guide frame 6 for measuring the fixed point of the line 4 to move up and down, and the reel 3 is connected to the fixed frame 1 by rotating the rotating shaft 2. There is a rocker on the reel 3, and a weighing unit is provided on the reel 3. The measuring wire 4 is wound on the reel 3 and passed through the guide frame 6 to connect with the hammer 5. The weight measuring unit judges whether the hammer 5 is touched. bottom and read the readings on the measuring line 4 to measure the depth of the cast-...

Embodiment 2

[0040] An implementation method of a simple cast-in-place pile hole depth measuring device, the implementation steps comprising:

[0041] S1. Depth measurement device assembly: install the moving part 12 of the assembled structure, the first fixed seat 7 connected with the second fixed seat 8 through the guide column 15, and install it on the outside of the top of the drilling rig head, and install the measuring system on the second On a fixed seat 7 and arranged alternately with the wedge-shaped push block 14;

[0042] S2. The first fixed seat 7, the second fixed seat 8 and the moving part 12 are arranged coaxially with the drilling rig by using the connecting steel rope and the fixed pile, and the horizontal position is limited;

[0043] S3. With the drilling of the drilling rig, the moving part 12, the slider and the wedge-shaped push block 14 move down as a whole, and the positioning rods 11 in the first fixed seat 7 and the second fixed seat 8 are extended to the wall of ...

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...
