Embodiment Construction

[0017] figure 1 It is a schematic diagram of the principle of a BIM-based tunnel overbreak and underbreak control method according to an embodiment of the present invention.

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. The present invention provides a method for controlling over- and under-excavation of tunnels based on BIM. The device for realizing the method includes a fully intelligent rock drilling rig control device and a central processing system, etc.;

[0019] The application method of the present invention is as follows: according to the geological design of the tunnel, the tunnel BIM model is made in the central processing system.

[0020] The secondary development of the central processing system of the central processor is carried out. The BIM model in the central processing system includes a geological analysis module, a drilling and blasting scheme selection modul...

Abstract

The invention discloses a method for overbreak-underbreak control of a tunnel based on building information modeling (BIM). According to the method, a full intelligent drill jumbo is connected with acentral processing unit of a user terminal, the precise positioning and multi-arm synchronous attitude adjustment of the drill jumbo are realized in the tunnel, multiple-drilling-arm automatic operation is achieved, and the peripheral contour of the tunnel and the positions of positioning boreholes are measured automatically. Geological analysis is carried out by combining advanced level drillinggeological exploration data with BIM technology analysis, according to drilling and blasting design matched with the implanted drilling and blasting design scheme, in cooperation with the constructionexperience of blasting personnel, the drilling and blasting design scheme is dynamically adjusted, and an LS-DYNA program is combined to perform drilling and blasting simulation, so that the best drilling and blasting program is formulated. The drill jumbo performs drilling according to the scheme, overbreak-underbreak is controlled strictly, and the intelligent and automatic management of personnel and machineries at a tunnel excavation construction site is realized, so that the control of overbreak and underbreak of the tunnel is achieved.

Description

technical field [0001] The invention relates to the related technical field of tunnel construction site technical management, in particular to a method for controlling over- and under-excavation of tunnels based on BIM. Background technique [0002] Excavation is a key process in tunnel construction. Too much over-excavation will not only increase the project cost due to the increase of slag discharge and lining volume, but also cause stress concentration due to local over-excavation, which will affect the stability of surrounding rock. Under-excavation directly affects the thickness of the lining, and it takes time and effort to deal with it. Although overbreak and underbreak are inevitable in drilling and blasting construction, certain measures can be taken to control the value of overbreak and underbreak to a small level, reducing the impact on construction cost, construction progress and tunnel safety. The influencing factors of overbreak and underbreak are divided int...
