Abstract

The invention discloses a protective shed structure for a continuous girder crossing an on-active-duty highway and a construction method of the protective shed structure. The protective shed structure comprises strip-shaped bases, stand columns and transverse load distributing girders, wherein the stand columns are fixedly arranged on the strip-shaped bases, and the transverse load distributing girders are set up on the stand columns; a set of longitudinal load distributing girders are arranged on each transverse load distributing girder, a waterproof board is arranged above the longitudinal load distributing girders, and steel pipe piles are fixedly arranged on the positions, at the two sides of the transverse load distributing girders, of the ground; and hawsers are arranged on the steel pipe piles, one ends of the hawsers are fixedly connected with the steel pipe piles, and the other ends of the hawsers are fixedly connected with the tops of the corresponding stand columns at the two sides of the transverse load distributing girders. The protective shed structure has the following characteristics and beneficial effects that the problem of large construction difficulty is solved by integrally hoisting and splicing the bases, the transverse girders and a longitudinal girder top layer, the problem of a high requirement for a safety factor is solved by building auxiliary facilities, and relatively good technical and economical benefits are achieved; and the transverse girders are removed by adopting the method of traction hoisting, and therefore the removing difficulty is reduced.

Description

Technical field [0001] The invention relates to the technical field of roadbed engineering, in particular to a continuous beam protection shed structure across active highways and a construction method thereof. Background technique [0002] In the current highway construction, the prestressed concrete continuous box girder technology is widely used in highway construction based on its beautiful structure and convenient construction. In order to avoid falling objects from high altitude during the construction of expressway prestressed box girder from affecting the normal operation of the existing line, and to prevent accidents, during the construction of the main structure across the existing line, setting up a safety protection scaffold has become one of the most effective measures to avoid accidents. It is widely used in road construction. [0003] In recent years, many expressway bridges have been built, and safety protection measures during construction are extremely important....
