COMPACTION OF THE SLOPES OF AN EARTH ROADBED ON A DIKE BY MEANS OF A VIBRATION-IMPACT MACHINE AT THE RIGA HYDROELECTRIC PLANT

A soil-compacting machine with vibration-impact operating elements was developed by the Central Scientific-Research Institute for Structures jointly with the Riga Maintenance Mechanical Factory of the Ministry of Transport Construction and is intended for layer-by-layer compaction of soils in the body of fills constructed from cohesionless as well as cohesive soils, over their entire width (including the edges). The base of the machine is a T-100MGP (or T-139G) tractor which supports bulldozer equipment at the front and tamping equipment consisting of a frame at the rear, with a spacial hanger which supports two vibration-impact operating elements driven from the tractor engine. To compact the edges of fills, the operating elements move from the tractor track to distance of 0.5-0.7 m from the external edge of the crawler belt. The experimental work made it possible to solve the problem of compacting the dike slopes and to eliminate the overfilling of the section with respect to the fill width; to increase the thickness of the placed soil layers to 0.9m; to determine the most rational tamping regimens; and, thus, to improve on the whole the techniques for carrying out the work under the given conditions.
