Equipment for preparatory works at implementation of trenches

Summary. Raising of problem. One of types of production of earthworks there is implementation of trenches under various engineering's buildings and technological communications. In military business there is a considerable necessity for similar works at implementation of trenches for shelter of personnel and trenches for the location of technique. In the case of production of works in winter, soils have considerably higher indexes of mechanical properties in comparing to other periods of year. For development of the frozen and strong s oils utilize bulldozers-rippers which execute preparatory works from loosening of such soils before work of basic earthmovers (power -shovels). After the requirements of production of trenches for military operations them lateral surfaces need to be execute d speak or with small inclination, that existent bulldozers-rippers do not execute. Purpose. Development of suggestions from the improvement of rippers for the increase of efficiency of preparatory works at implementation of trenches . Conclusion. Implementation of trenches in the frozen and strong soils is related to the necessity of their development rippers indents of which establishment rakish. The use of rippers with indents rakish provides implementation of trenches with vertical surfaces and promotes the productivity in 8,5.9,0 times in comparing to rippers of traditional construction.
