Earthquake-proof coupling of concrete box culvert

摘要

Topic To slip between such as concrete box culvert and with the vibration, bombardment and ground subsidence etc of earthquake and the like the movement occurring and the female edge due to inlaw fit and the gap between the male end spreading dying continuing to maintain the pressure welding of the rubber cycle which is pressed in offer the earthquake-proof coupling of the concrete box culvert which water leakage that tries does not occur.Solutions It designates the outside as the even surface, attaches outward-opening inclination on the inside, directs to the outer edge and it attaches the deviation from die possible rubber board molding box which gradually forms the light-gage to peripheral surface and it uses the inner mold which facilities is done and in order to be parallel with the direction of inlaw fit mutually at the same time with the inside 2of a the female edge 2 of the concrete box culvert which formed and the outside 3of a male end 3 as a husband Various even forma, it forms, the female edge it slips in the fit section of 2 and male end 3 with earthquake and the like, the movement occurring, the female edge between internal surface 2of a 2 and male end 3 and 3aThere is no thing where the opening 4 spreads to internal surface direction, rubber cycle 5 pressure welding will continue to make both of internal surface 2a and 3a constituted.
