Connection method and structure for variable-section continuous rigid frame aqueducts
The invention discloses a connection method and structure for variable-section continuous rigid frame aqueducts. The connection method comprises the steps that a transition aqueduct is arranged between the single-hole aqueduct and the two-hole aqueduct, the single-hole aqueduct and the two-hole aqueduct with different sections are connected together smoothly through the transition aqueduct, and sudden connection change generated in the connection position of the single-hole aqueduct and the two-hole aqueduct is avoided; and meanwhile, a base plate of the transition aqueduct is provided with a water-stop device through which water is prevented from gradually seeping into the connection position, and the base plate of the transition aqueduct is prevented from being corroded. According to the connection method and structure, the problem that the connection stress of an existing connection structure is reduced due to sudden connection change generated in the connection position of the single-hole aqueduct and the two-hole aqueduct is solved through the method that the transition aqueduct is added to the connection position of the single-hole aqueduct and the two-hole aqueduct. Meanwhile, the water is prevented from gradually seeping into the connection position through the water-stop device, so that the deficiency that the water seeps into the connection position, the base plate of the transition aqueduct is corroded, and consequently corrosion damage is generated to structural concrete and reinforcing steel bars, cracking of construction joints is generated finally, and accordingly the durability of the aqueducts is severely influenced, and even the safety of a structure is affected are overcome.
