Description

TECHNICAL FIELD

[0001] The utility model relates to solar energy photo-thermal power generation engineering construction civil engineering construction technical field, concretely relates to a pile foundation aperture hole depth measuring device. BACKGROUND

[0002] In the process of pile foundation construction of the light and heat engineering collector mirror field, the aperture and hole depth measurement after hole forming is a very important link, which is directly related to the construction quality of the subsequent pile foundation and the stability of the whole project.

[0003] At present, the aperture and hole depth are mostly measured by steel tape. Steel tape is a common measuring tool, which has certain portability and universality. However, due to the relative lack of toughness of the material of steel tape itself, when measuring the hole depth, the steel tape needs to be stretched into the hole, and the steel tape is easy to bend under the action of its own gravity and friction with the hole wall. This leads to the inability to accurately reflect the actual hole depth, resulting in errors in the measurement results. Such errors may make the construction personnel inaccurate in judging the hole depth, thereby affecting the accuracy of the subsequent pile foundation construction. The actual operation efficiency is low.

[0004] When measuring the aperture, the steel tape can only simply measure the diameter of the hole mouth. The diameter of the hole, especially the bottom of the hole, cannot be known, and it cannot be ensured that the diameter of the hole and the bottom is consistent with the diameter of the hole mouth, and the real situation of the aperture cannot be fully understood. In addition, the steel tape cannot detect whether the hole is drilled. If the deviation is not found in time during the construction process, the pile foundation verticality will not meet the requirements when the subsequent pile foundation construction is carried out. The pile foundation verticality does not meet the requirements, which will affect the bearing capacity and stability of the whole structure, and rework is easy to occur, causing waste of manpower and material resources.
