Embodiment

[0038] A multi-point aperture displacement measuring device of the present invention, such as figure 1 As shown, it includes the orifice support 1, the in-hole measuring point component 2 and the data acquisition box 8. According to the drilling depth, the number of in-hole measuring point components 2 is three, and the orifice support 1 and three in-hole measuring point components 2 are connected in series, and the data collection box 8 has its own solar panel 7 to ensure the power consumption of the data collection box 8. The data collection box 8 is connected to a computer 10 through a GPRS module 9, and the data is transmitted to the computer 10 for analysis and processing.

[0039] The measuring point component 2 in the hole is a point contact component, such as Figure 2-4As shown, the measuring point member 2 in the hole includes three sleeves 16 and two sleeve connection plates 15, the three sleeves 16 provide three measurement directions, the three sleeves 16 are arra...

Abstract

The invention discloses a multi-point aperture displacement measuring device, and the device comprises an orifice support, an in-hole measuring point component and a data acquisition box, wherein the orifice support and the in-hole measuring point component are sequentially connected in series. The measuring range is large, and the measuring requirements of different heights in multiple directions can be met. The invention further discloses a hole diameter displacement measuring method, and the method comprises the steps that the hole opening support and the in-hole measuring point components are sequentially connected in series, the in-hole measuring point components which are connected in series are vertically placed into a drill hole, the hole opening support is placed at the position of a hole opening, all data transmission lines left on the ground are connected to the data collection box, an unbuckling rope is pulled, a lock catch is opened, the roller makes close contact with the side wall of the drill hole and does not move any more, displacement data are collected, analyzed and processed, and the measurement of aperture displacement is completed. The precision meets the measurement requirement, the aperture displacement data change condition can be mastered in real time, the measurement process is stable, and the measurement result is accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering measurement, relates to a multi-point aperture displacement measurement device, and also relates to an aperture displacement measurement method. Background technique [0002] In the process of pile foundation construction, the quality of hole formation has always been the focus of attention of engineers and technicians. The hole diameter is the key factor affecting the quality of the pile body. It is necessary to grasp the variation law of the hole diameter under different geological conditions during the construction process to select a reasonable one. Construction plan and method of laying piles. [0003] Commonly used aperture detection methods are: ball type, steel cage type, hexagonal wooden hinge type, caliper type, acoustic wave detection method, mechanical contact detection method, etc. The principle of the ball-type simple method is simple and easy to understand, and it ...
