AGGREGATE FOR SINKING WITH REINFORCEMENT OF BASIS FOR WINTER SNOW ROAD ON BOGS Russian patent published in 2009 - IPC E01C19/26 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to machines for preparation of basis for construction of winter roads on swamps, particularly to machines for sinking with superficial reinforcement of frozen swampy basis in north conditions. Aggregation for sinking with reinforcement of basis for winter roads on swamps contains frame of the first stage and frame of the second stage connected to each other by means of joint, through which at rotations it is provided free rotation of the first stage relative to the second. Additionally the first stage corresponds single-row road roller with air castors, the second stage of aggregate consists of two steel drums and one road roller between them, on surfaces of the first and the second steel drums there are mounted elongated projections of triangular shape. To each other by angular deflection drums are connected by lamellar chain drive so, that elongated project of the second drum are fed on base of road bed into midsection between rows of grooves against impression of projections of the first drum with shift in the longitudinal line for half of length of elongated projection. On axis of the first and the second steel drums there are mounted hydraulic actuators. On frame of the first stage it is installed equipment for hydraulic actuator. On frame of the second stage it is installed equipment for electric and heating power production.

EFFECT: invention is directed to increasing of quality and durability of prepared surface of swamped basis for winter roads, effectiveness of sinking process and acceleration of freezing process of powder with snow, sinking swamped surface.
