Abstract
Description
Technical Field
[0001] This invention relates to the field of rail transit technology, specifically to an automated calculation and design method for grouting reinforcement engineering quantities in rail transit tunnels. Background Technology
[0002] In the field of rail transit construction and maintenance, tunnel grouting reinforcement is a key engineering technology to ensure tunnel structural stability and prevent water leakage and ground settlement. Accurate and efficient calculation and design of grouting reinforcement work is crucial for controlling project costs and ensuring construction progress.
[0003] Currently, the commonly used methods for calculating and designing the grouting reinforcement work in railway tunnels mainly rely on the manual operation and experience judgment of designers. The typical process and existing technical problems are as follows: 1) Low level of automation and low efficiency: The entire process is highly dependent on manual labor. From data extraction and parameter calculation to result summarization, designers need to be involved at every step. When faced with tunnel sections of tens or even hundreds of kilometers, it often takes dozens of working days to complete the calculation of the entire line's engineering quantity (such as about 60 working days for a certain subway project), which seriously restricts design efficiency.
[0004] 2) Calculation accuracy is difficult to guarantee: The large amount of manual operation and complex mathematical calculations significantly increase the risk of misreading, misrecording and calculation errors in the process, which directly affects the accuracy of the engineering quantity calculation and may cause deviations in the project budget and material procurement.
[0005] 3) Insufficient digitalization and intelligence: Design parameters are scattered across drawings, failing to form structured digital assets that cannot be directly accessed and processed by computer programs. Any adjustment to the design scheme requires manual re-execution of the entire calculation process, resulting in high costs for scheme iteration and optimization, which cannot meet the demands of modern engineering for rapid response and precise design.
[0006] 4) High workload and waste of resources: Binding professional and technical personnel to repetitive and mechanical data sorting and calculation work is a huge waste of human resources and also affects designers' ability to focus on more creative design optimization work.
[0007] Therefore, the industry urgently needs an automated calculation method that can automatically acquire parameters, intelligently calculate key geometric parameters, and generate engineering quantities with one click, so as to fundamentally improve the efficiency, accuracy, and intelligence level of the design work for grouting reinforcement in rail transit tunnels.

[0013] More preferably, in step S4, the grouting reinforcement radius R inside the rail transit tunnel is calculated by adding the lower offset value d_l of the grouting reinforcement range inside the tunnel to the tunnel radius r, i.e., R = d_l + r.
[0014] More preferably, the angle D of the grouting reinforcement range inside the rail transit tunnel is calculated using the following formula:

[0020] Compared with existing technologies, the automated calculation and design method and device for grouting reinforcement engineering in railway tunnels provided by this invention can bring the following significant benefits: 1. It has achieved full automation and intelligence in the design process, significantly improving work efficiency. This invention integrates the previously fragmented and manual processes of data extraction, parameter calculation, and quantity aggregation into a continuous and automated workflow through the development of a secondary development program deeply integrated with AutoCAD. Designers only need to start the program and specify the calculation range; the system automatically reads key parameters from the design files and completes all complex calculations and outputs results based on embedded geometric algorithms.
