Problems solved by technology

The traditional construction method is to use the ground support method to cast the end section of the beam first, and then use the hanger to close it. The construction procedure is more complicated and the construction period is longer.
In particular, in recent years, with the construction of continuous rigid frame bridges with high piers in mountainous areas, high supports have to be erected at the end of the side-span beams in cast-in-place construction, resulting in a significant increase in construction costs and technical difficulties

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 and figure 2 As shown, the overall construction method of the hanging basket on the straight section of the side span of the high-pier continuous rigid frame bridge and the cover beam support is: the steel bars are bound and formed at one time, and the pouring is carried out in two times; that is, the hanging basket is used for the first time. One section, the remaining solid section in the second pouring, most of the solid section falls on the cover beam, and only a small part falls on the hanging basket. see figure 1 , the high-pier continuous rigid frame bridge includes the middle pier 7, the side pier 8, and the mid-span 5 and side span 6 supported on the middle pier 7 and the side pier 8, wherein the mid-span 5 and the side span 6 in the middle are poured beam sections The side is the straight line sec...

Abstract

The invention discloses an integral construction method of the straight section of the side span of a high-pier continuous rigid frame bridge with a hanging basket combined with a cover beam support. The steel bars are bound and formed at one time, and the pouring is carried out twice; The remaining solid section of the second pouring; most of the solid section of the second pouring falls on the cover beam, and a small part falls on the hanging basket. The invention has the advantages of being able to simplify the construction procedure, save the construction period, save the construction cost and the like.

Description

technical field [0001] The invention mainly relates to the field of bridge construction, in particular to an overall construction method mainly applicable to the straight section of the side span of a continuous rigid frame bridge with a high pier and a hanging basket combined with a cover beam support. Background technique [0002] Prestressed concrete continuous rigid frame bridges are widely used in long-span bridges due to their advantages in mechanics and economy and the development of hanging basket cantilever construction technology. The straight line section of the side span is the main stress-bearing part of the continuous rigid frame bridge and the construction difficulty. Considering the structural stress, the design length of the side-span straight section is generally greater than the length of the cantilever pouring section, which is divided into two sections: the beam end section and the closing section. The traditional construction method is to use the groun...
