Foreword

This regulation was formulated in accordance with the requirements of China Engineering Construction Standardization Association (96) Jianbi Xiezi No. 10 "Letter on Releasing the 1996 Recommendation Standard Preparation Plan".
At present, the popularization and application of rigid polyvinyl chloride pipes for buried drainage pipes in China has begun. Through the engineering practice in various regions, the effect is good. This regulation is based on the results of indoor and outdoor test research and engineering pilot application of rigid PVC drainage pipe systems in the past six years by Tianjin Municipal Engineering Research Institute and Shanghai Municipal Engineering Research Institute and other units. Prepared by the standard. At present, domestic production of rigid PVC pipes that can be used for buried drainage pipes has many specifications and different performances, and it is impossible to detail them in this regulation. The provisions of this code are mainly used in the drainage pipeline project, which is the most widely used double-wall corrugated pipe and annular rib pipe. It has strong versatility. When applying other types of pipes, refer to the relevant provisions in the provisions.
In accordance with the requirements of the State Planning Commission [1986] No. 1649 "Notice on Inviting the China National Engineering Construction Standardization Committee to Organize the Pilot Work of Recommended Engineering Construction Standards", the Association's Standard "Technical Regulations for Buried Unplasticized PVC Drainage Pipeline Engineering" is now approved The serial number is CECS 122: 2001, and it is recommended for engineering construction design, construction and use units. This Regulation is under the centralized management of the Pipeline Structure Committee (TC17) of the China Engineering Construction Standardization Association, and is explained by Tianjin Municipal Engineering Research Institute (39 Pingshan Road, Hexi District, Tianjin 300074). If you find that you need to modify or supplement in use, please send comments and information to the explanation unit.
