渠道防渗防冻复合衬砌结构的研究

Study of the Complex Lining Structure for Seepage and Heave Damage Control of Canal,

在我国北方地区的渠道衬砌工程中,存在着因基土冻胀而造成的衬砌破坏问题。本文提出了以珍珠岩板作为衬砌渠道防冻胀新材料,以及制作珍珠岩板和混凝土防渗板相结合复合板的生产工艺。这为我国季节性冻土地区渠道防渗工程的设计提供了依据。

In the canal lining projects in the northern part of China exist some problems concerning lining damage which is caused by frost heave. This paper presents that pearlite colony slabs can be taken as a kind of new material for frost heave prevention of the canal linings. The paper also puts forward productive technology of composite slabs made of pearlite colony slabs and concrete slabs. It provides experience for the design of canal leak-proof engineering in the seasonal frozen-earth districts of China.
