Summary: | road building; overbridges, tunnels. SUBSTANCE: invention relates to construction of overbridges and tunnels for new motor roads and reconstruction of existing motor roads. Proposed tunnel-type overbridge has base, side and central walls assembled from reinforced concrete panels, and floors assembled from beans arranged across longitudinal axis of tunnel and resting through monolith butt-joints against one of side and one of central walls assembled from reinforced concrete panels which are arranged parallel to each other with displacement relative to longitudinal axis of overbridge in its central part through a certain distance relative to each other. Monolith butt-joint with beams of floor above exceeds in plan indicated distance between central walls 1.3 times, minimum. EFFECT: cut down labor input, increased rate of construction at provision of adaptability to manufacture at any season of the year. 3 cl, 1 dwg |
