The tests research of blasting vibration simulating earthquake were carried out by a reinforced concrete pipe embedded landscape orientation and hangfire.

摘要通过埋置钢筋混凝土管约束爆破的竖向震动，采用延时爆破方式进行模拟天然地震的试验研究。

Epoxy or plastic liming may be cast into the concrete pipe during manufacture;or bitumastic or coal tar epoxy may be painted on the concrete pipe surfaces after installation.

可以在制造混凝土管道时将环氧和塑胶衬里浇筑在里面，或在安装后用沥青砂浆或煤焦油屠宰混凝土管的表面。
