Abstract

Abstract:

Bad construction environment is usually a difficulty for construction schedule. The membrane filter dust method and portable CO detector are used respectively to monitor the construction dust and CO of Jichoushan tunnel, and the statistical method is used to analyze the monitored data, so as to learn the consistence and distribution laws of construction dust and CO. The results show that there are great differences among different consistence of construction dust and CO, and trackless mucking has a great influence on construction environment. The control technologies for construction dust and CO are proposed, and field testing is carried out. The paper can provide references for environment control of similar projects in the future.

Key words: high altitude cold area, Jichoushan tunnel, harmful gas, monitoring, control technology
