PVC模块内衬法在排水管道非开挖修复中的应用

Application of BIM Forward Design in Expressway Interchange Engineering

摘要:

随着社会经济的快速发展，人们对城镇环境和防汛排水安全也日益重视，排水管网担负着收集和输送雨、污水的作用，是城镇防汛排水保障的重要基础。在排水管道运行使用的过程中，因排水管道结构性损坏造成的污染地下水、地面沉陷事故时有发生。非开挖修复技术可实现在交通繁忙的路段对排水管道的维修更新，结合实际案例，论述PVC模块内衬法在城市排水管道非开挖修复中的应用。

Abstract:

At present, BIM design generally adopts "reverse mold", which leads to low efficiency. Firstly, the key points of BIM intercommunication design are expounded. Secondly, taking the interchange section of Shangpu Expressway as the engineering background, based on Civil 3D and Revit, three key steps of BIM forward design of terrain curved surface, 3D road model and bridge family library are analyzed. The research results show that the designers have greatly improved the design accuracy and design efficiency profited from the unique visual operation and dynamic update mechanism of BIM design.
