Problems solved by technology

Therefore, the paving operation mostly depends on the construction experience and proficiency of the bulldozer operator, resulting in a large difference between the operation efficiency and the paving quality
At the same time, with the development and promotion of water conservancy and hydropower projects, more water conservancy and hydropower projects are constructed in high-cold and high-altitude areas. Harsh environments such as lack of oxygen and low temperature will reduce the accuracy of analysis and control of bulldozer operators, making it difficult to realize paving operations. efficient control of

Embodiment approach

[0046] The specific implementation is as follows:

[0047] 1. Use the Beidou measuring rod to measure the coordinates of each corner point of the warehouse surface, build the warehouse after the supervisor agrees, obtain the on-site warehouse building information, and obtain the real-time position information and historical position information of the bulldozer based on the paving real-time monitoring system, and construct the coordinates of the warehouse surface, Elevation correspondence;

[0048] 2. Write the warehouse surface coordinates and elevation correspondence obtained in step 1 into the cell as the basis for its calculation;

[0049] 3. Develop a visual simulation platform, and use visual methods such as AR technology to provide real-time feedback on site construction. The specific implementation is as follows:

[0050] a) Based on the simulation model, perform visual analysis, and express the optimal direction of the bulldozer at this moment in the form of an arro...

Abstract

The invention belongs to the technical field of water conservancy and hydropower, and particularly relates to a method for intelligently controlling the paving quality of an earth and rockfill dam. The method comprises the steps of abstracting the paving process according to the characteristics of the paving process, and establishing a paving process simulation model; secondly, according to the paving process simulation model, based on paving process data obtained in real time and in combination with the construction experience of paving operators, establishing an intelligent simulation and path planning method of paving operation, and achieving intelligent control over the paving quality; and finally, based on a visual analysis method, establishing paving operation path real-time feedback, and achieving real-time guidance of the paving operation process . According to the invention, the degree of dependence on the construction experience of operators in the paving operation process can be reduced, the paving operation quality is improved, and the standardization, normalization and intellectualization of the paving operation are realized.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower, and in particular relates to a method for intelligently controlling the paving quality of an earth-rock dam. Background technique [0002] Compared with most types of civil engineering, the construction of water conservancy and hydropower projects has the characteristics of long construction period and complex construction conditions. How to improve construction efficiency while ensuring construction quality is a difficult problem that all builders are very concerned about. The center wall rockfill dam is a relatively traditional and technically mature dam type, and has been widely used all the time. With the development of water conservancy projects, the scale of core rockfill dams has become increasingly large. For example, a core rockfill dam currently under construction in southwest China has a dam height of 295.0m and a total fill volume of about 41.6 million cubic m...
