SUBSTANCE: invention relates to permanent way designed to take up load from rolling stock. Frame base consists of reinforced concrete frame ties placed in row on crushed stone ballast layer. Each tie is made of reinforced rigidly interconnected two longitudinal (sleeper) parts and two crossmembers forming rectangular frame with hollow middle part with trapezoidal section projections with underrail pads in places of connection of longitudinal parts. Crossmembers of frame tie are rigidly connected with longitudinal parts by inner faces of longitudinal parts at right angle, and outer face of longitudinal part of each frame tie has smooth surface. Shaped cutouts are made on crossmembers of each frame two sides. Cutouts on inner side are used to form space in inner part of tie in form of cell, and those on outer side, to form cell between adjacent frame ties equal to inner cell. Rail fastenings of adjacent frame ties are arranged at constant pitch equal to distance between axes of frame crossmembers. At approaches to bridges, tunnels and overhead roads, reinforced concrete frames are laid in crossmembers of which over their entire length and flush with upper surface tubular rectangular section parts are imbedded to which "shuttle-like" joint ends of counter-rails or counter-angles are fastened by means of bolts with T-head through holes of corresponding shape made in place of fastening. Method of construction of underrail base comes to the following: frame ties are placed on ballast layer with clearance between adjacent frames to provide free access to ballast layer for tamping mechanisms from outside and inside of longitudinal parts of reinforced concrete frames. Clearance is found from following equation: H=0.5B where H is value of clearance; B is width of cell between crossmembers inside each frame. Rail fastenings of adjacent frame ties are installed at constant pitch equal to distance between axes of frame crossmembers.
EFFECT: reduced labor input and volume of work, improved stability of rail track, reduced expenses possibility of laying "shuttle-like" joined ends of counterrails of counter-angles at approaches to bridges, tunnels.
