Problems solved by technology
This scheme has a more significant construction treatment effect for shallow karst caves, and relatively difficult construction treatment for deep karst caves, with a large amount of personnel input, and the project cost is cheaper than the first scheme, but the concrete diffusion coefficient of the pile body is relatively low. Large, and due to too many objective factors in the process, the construction period is very unstable

Embodiment Construction
[0023] The present invention provides a BIM-based karst cave treatment method. Before implementing the present invention, the geological conditions of the geological conditions to be constructed must be analyzed by means of advanced drilling and exploration, and each foundation pile hole is explored to obtain Get the drilling histogram of each pile hole, the drilling histogram includes drilling coordinates, drilling depth, hole elevation, description of the soil quality of the stratum, depth of layer bottom, thickness of layer, elevation of layer bottom, etc. Then the cave is processed by the present invention, which specifically includes the following steps:
[0024] (1) The distribution of karst caves and engineering piles are expressed through the BIM three-dimensional model, including:
[0025] Through the BIM software, the drilling histogram obtained from the advanced drilling survey is converted into a corresponding three-dimensional model of cave distribution. Specific...

The invention provides a karst cave processing method based on BIM. The method includes the following steps that first, distribution of karst caves and distribution of engineering piles are represented through BIM three-dimensional models; second, the three-dimensional model of distribution of the karst caves and the three-dimensional model of distribution of the engineering piles in the first step are combined in BIM, and the spatial position relation between the engineering piles and the karst caves is simulated; third, an analysis report about the situation that each engineering pile passes through the corresponding karst cave is provided; fourth, dangerous karst caves are screened according to the simulated spatial position relation between the engineering piles and the karst caves and the analysis reports; fifth, the dangerous karst caves screened in the fourth step are preprocessed, and the other karst caves are post-processed Due to the karst cave processing method based on BIM, the karst caves can be classified, the construction period is greatly shortened, construction quality is guaranteed, and engineering cost is reduced.
Description
technical field [0001] The invention relates to a method for treating karst caves based on BIM, and belongs to the technical field of foundation and foundation engineering. Background technique [0002] Building information modeling is a new tool in architecture, engineering and civil engineering. Building Information Modeling (Building Information Modeling, referred to as BIM), is defined as a building or construction engineering information model that is composed of complete and sufficient information to support life cycle management, and can be directly interpreted by computer applications. In short, it is the life cycle management of the built environment supported by digital technology. [0003] In construction engineering, it is not uncommon for the construction of engineering piles to encounter karst caves, especially in areas where karst caves are widely distributed and the scale of karst caves is large. The construction quality of engineering piles is difficult to...
