Measuring device and measuring method for constructional engineering investigation

Abstract

The invention discloses a measuring device and a measuring method for constructional engineering investigation, and belongs to the technical field of constructional engineering investigation. The measuring device can be buried in a foundation for a long time for strength detection through a pre-burying mode, and the detection means is mainly a gravity extrusion effect of a bipolarity pressure ball on a liquid isolation film. Pressure in a pre-buried cylinder is changed to force a pressure change film to expand towards the outer side. A self-breaking rod is broken by pulling, a self-luminous floating ball gets close to the bipolarity pressing ball and makes contact with the bipolarity pressing ball under the action of magnetic attraction after being recovered to be free, the self-luminous floating ball can trigger a light emitting phenomenon after making contact with the liquid isolation film and being squeezed, different self-luminous floating balls release light of different colors, and the light is sequentially conducted to an outer developing rod. A technician can regularly observe the color and the intensity of internal light through the outer color developing rod every day so as to judge the intensity change of the foundation. Compared with an existing measuring device, the measuring device can carry out measurement autonomously, information is fed back in a light emitting mode, and the measuring device is quite efficient and intuitive, and can be used for night illumination so as to save electricity.

Description

technical field [0001] The invention relates to the technical field of construction engineering survey, more specifically, to a measurement device and a measurement method for construction engineering survey. Background technique [0002] Construction project survey refers to the activities of identifying, analyzing and evaluating the geological and geographical environment characteristics and geotechnical engineering conditions of the construction site according to the requirements of the construction project, and compiling the construction project survey documents. [0003] The basic content of construction engineering survey is engineering survey, hydrogeological survey and engineering geological survey. The survey task is to find out the natural geological conditions data such as topography, stratum soil lithology, geological structure, hydrological conditions, etc. of the project construction site, make identification and comprehensive evaluation, and provide scientific...

Problems solved by technology

[0006] However, since the geological conditions are not static, they are greatly affected by external factors, and even the strength of the foundation will change due to changes in weather and temperature. Therefore, repeated high-frequency measurements are required, and conventional measurement devices are too time-consuming and laborious to use.
