摘要

construction engineering; applicable in construction of main pipelines. SUBSTANCE: steel isolated pipeline is laid into trench on preparation layer treated with binder, filling of cushioning layer of ground treated with binder and filling up of pipeline with ground. Preparation layer contains organic binder in amount of 10-15% of ground weight. Cushioning layer amounts to 8-12% of ground weight. Filling layer and fill ground also contain organic binder in amount of 8-12% of ground weight. EFFECT: increased pipeline reliability. 3 cl, 1 dwg
