PROCESS OF ERECTION OF MONOLITHIC REINFORCED CONCRETE BRIDGE SUPPORTS-WALLS Russian patent published in 2003 - IPC

Abstract RU 2208082 C2

FIELD: bridge construction. SUBSTANCE: process can find use in erection of various structures, in all cases when substantial interruption in laying concrete in foundation or chute on one side and walls of vault of tunnel or tube on other side is anticipated. Process includes operations of preparation of base for support-wall, mounting of attachments and reinforced cage for concrete laying in foundation and wall. Salient feature of process lies in that operation of preparation of base includes arrangement of thixotropic underlayer, concrete in foundation is laid in individual blocks along length of structure with arrangement of expansion joints between adjacent blocks. Length of each block encased in concrete is established from two conditions L≤15 m and L≤kh m where h is height of erected wall, m; k=0.8...1.5 is correction factor depending on local conditions. Wall is treated with concrete over entire length and height. EFFECT: increased resistance of monolithic reinforced structures to cracks. 4 dwg
