FIELD: construction.SUBSTANCE: method to eliminate deformations of bridge crossing abutments includes increasing the support area of abutments by erection of a solid shell around them. Previously along the contour of the support part of shells there are waterproof screens erected by means of injection of a water-impermeable composition into soils of abutment bases, monolithic reinforced concrete shells are erected at three sides of each abutment from the level of its foot, shells are connected with each other by a spacer beam. In support parts of the shells, every of which has width exceeding the width of the appropriate abutment, there are through holes made, through which fixing solutions are injected into the soil base of abutments.EFFECT: increased efficiency and reliability of elimination of deformations of bridge crossing abutments erected on a soil base with insufficient bearing capacity.3 dwg |
