Description

Technical Field

[0001] The utility model relates to the technical field of seepage detection equipment, and in particular to a dam foundation seepage detection device based on BIM simulation. Background Art

[0002] The key point and one of the advantages of BIM technology application is to assist in various decision-making and strategic planning through realistic pre-analysis and simulation before the project is actually carried out, so as to reduce or even avoid misunderstandings, conflicts, errors, waste and risks that may occur in the project.

[0003] Most of the existing dam seepage detection devices can only detect one seepage point at a time. In order to improve the accuracy of the detection results, the staff needs to conduct multiple mobile detections to obtain more experimental data, which is inconvenient to use. When the detection device detects seepage, the water pressure is generally constant, and the water pressure cannot be flexibly changed for seepage detection. In water conservancy projects, the height of the dam is very high, and many parts are submerged in water. The water pressure of the dam at different water depths is also different, so its seepage conditions are also different, which can easily lead to a generalization of the test data and affect the accuracy of the detection results.

[0004] Publication (Announcement) No.: CN113358543B discloses a BIM-based simulated seepage intelligent detection device and method for water conservancy projects. A fixed plate is arranged at the upper end of the pneumatic slider, a moving rod is arranged through the side wall of the fixed plate, a main detection probe is arranged at the end of the moving rod close to the sample fixing groove, and a limiting sleeve is arranged on the side walls around the main detection probe to movably sleeve the middle rod. A secondary detection probe is arranged on the outer wall of the end of the middle rod close to the sample fixing groove, and the ends of the middle rod are movably connected to the side wall of the moving ring through a connecting rod. The moving ring is movably sleeved on the outer wall of the moving rod. The moving ring is connected to the fixed plate through a buffer spring. The pneumatic slider pushes the fixed plate to move, and the moving ring compresses the buffer spring and slides on the moving rod. When the moving ring moves, it drives the connecting rod to stretch the middle rod to move to the outside of the limiting sleeve port, and randomly adjusts the distance between the secondary detection probe and the main detection probe, so as to detect seepage at multiple points of the detection probe at the same time.

[0005] The existing detection device has a good detection effect, but has a complex structure, high cost, is not flexible enough to use and carry, and cannot be widely used. Utility Model Content
