Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and in particular relates to a construction engineering foundation detection and measurement tool. Background Art

[0002] Construction projects refer to the engineering entities formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. "Buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, residence, study, and public activities.

[0003] The utility model with the authorization publication number CN217083594U provides a hole diameter measuring device for surveying and mapping of foundation design of construction projects. The hole diameter size can be effectively measured through the electric telescopic rod and auxiliary roller on the counterweight block, and the auxiliary roller can be rotated to facilitate downward movement and measurement of hole depth.

[0004] However, in the above patent, after the winding roller releases the measuring rope for measurement, it is difficult to evenly wind the measuring rope around the outside of the winding roller again. The measuring ropes are easily stacked and crossed, and are damaged by friction with each other, which shortens the service life of the measuring ropes. At the same time, many electrical control devices are arranged on the device, which makes the device dependent on electricity to work, which is inconvenient for long-term outdoor measurement on the construction site. For this reason, we propose a construction engineering foundation detection and measurement tool. Utility Model Content
