The design of the working body planner slopes for liner-tamping-finishing machine VPO-3000. Based on the analysis of existing designs of planners ball-fin track machines (VPO-3000,SZP-600R,PB-01,SS-3,ELB-3MK,ELB-4K),finding to operate on a network of West-Siberian Railway selected under the most-walked analogue - plow machine SZP-600r.The proposed project design of all structural elements of the plow SZP-600R has been changed in view of the desired trajectories scheduler slopes and its geometrical layout on the machine VPO-3000,as well as taking into account the requirements of the design and of top-Story-of way,in particular gravel ballast,after work on her cleaning ballast cleaner MF-600. The selection of geometric parameters and the calculation of design elements scheduler slopes are made using APM WinMashin programs according to the real conditionscess of the load operation and,in particular: arrow with the plow is in working position and performs cutting and Zdzvizhkou crude ballast for support of contact network; arrow disclosed at the maximum angle ?; plows are not disclosed and are located along the axis of the boom. The developed design planner slopes allows removal of contaminated ballast portion of the railway line,as well as other operators,radio planning prism slopes. The proposed project will improve the machine VPO-3000 allows the excluded-tained from the technological process of modernization of railroad tracks Add-tional machine to remove the contaminated site ballast,which reduces the cost of performing the work.

The use of three-dimensional reinforcing structures is an effective method strengthen the slopes and the primary site of subgrade, it is confirmed by a complex of experimental studies. The numerical and natural modeling processes associated with the strengthening of subgrade geokompozitn structure. Natural modeling performed by the embankment of equivalent materials using real ground conditions and loadings identical in size natural. A comparison of simulation results showed high convergence, which allows use it’s in the preparation of design techniques.
