A method for erecting a split steel bridge

Abstract

The invention discloses a split type steel-framed bridge erection method, comprising the following steps: 1, erecting a first bridge body which is in a folding state, enabling a rotation center of the first bridge body to be positioned at the upper part, enabling the two ends of the first bridge body to be positioned at the lower part, and connecting one end of the first bridge body with a base in a pivoting way; 2, arranging a retracting and expanding mechanism on the first bridge body, driving the first bridge body to unfold by means of the retracting and expanding mechanism, and controlling the first bridge body to gradually descend; 3, pushing a second bridge body onto the erected first bridge body, connecting one end of the second bridge body with the first bridge body after the second bridge body is in place, arranging another retracting and expanding mechanism on the second bridge body, unfolding the second bridge body by means of the retracting and expanding mechanism, and controlling the other end of the second bridge body to gradually descend until being jointed with the first bridge body; 4, disconnecting the first bridge body from the second bridge body, connecting the first bridge body with the second bridge body at the sides in a pivoting way, and then lifting the second bridge body to enable the second bridge body to rotate relative to the first bridge body. The method provided by the invention is very ingenious, and has the advantages of being low in energy consumption and high in efficiency.

Description

technical field [0001] The invention relates to a method for erecting a split steel bridge. Background technique [0002] In some emergency situations, it is necessary to quickly build bridges on rivers or ravines. At this time, in order to ensure the rapid construction of bridges, split steel bridges are generally used to solve this problem. However, existing methods for erecting split steel bridges exist Some problems, such as needing to be equipped with relatively large counterweight, extremely high energy consumption, insufficient erection efficiency and other shortcomings, for this reason the present invention provides a method for erecting a split steel bridge. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for erecting a split steel bridge. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A method for erecting a split-type steel-framed bri...
