发明名称 METHOD FOR PRODUCTION OF CAST-IN-PLACE FOUNDATIONS OF HIGH-SPEED RAILWAYS
摘要 erection of cast-in-place lengthy concrete and reinforced- concrete constructions with the aid of horizontal slip forms, applicable, for instance, for erection of cast-in-place foundations of high-speed (300 to 350 km/h) railways. SUBSTANCE: the method consists in placement of concrete mix, moulding of line section with the aid of the board of the horizontal slip form, installation of expansion bolts, making-off of functional joints, hardening of concrete; moulding of the foundation complex section is performed by a vibrostamp simultaneously with installation of expansion bolts and making-off of functional joints, the vibrostamp acts on the line section with a periodicity of 2 to 5 min. EFFECT: reduced labour content and power intensity. 10 dwg
