FIELD: bridge-building industry. SUBSTANCE: this cuts number of joints, increases service life of support, reduces consumption of material and labour intensity during construction and operation of support. Sectional-monolithic support of bridge has foundation, single- and/or multiple-level above-foundation structure which is made up of monolithic core and embracing vertical contoured blocks of trapezoidal cross-section which are of height equal to height of level of its above-foundation structure. Lower ends of blocks are built in foundation, and upper ends of blocks are combined to each other by means of connecting rods. Vertical side faces of blocks standing close to each other create angle of 20 to 120 deg. between themselves. EFFECT: higher efficiency. 4 cl, 11 dwgs |
