Problems solved by technology

[0003] At present, an independent box girder prefabrication field is required to manufacture box girders at the construction site. The inventors have found that the current box girder prefabrication field is prone to uneven settlement due to the weight transmission of the box girder when making box girders, making the girder base The table is uneven, resulting in poor precision and substandard quality of manufactured box girders

Abstract

The invention discloses a construction method for a beam-making platform and a construction method for a box beam prefabricated factory and relates to the technical field of beam factory construction.The construction method comprises the following steps: throwing tubular piles into the ground in a preset area; pouring the tops of the tubular piles and forming pile caps; pouring the pile caps andforming foundation beams; and pouring the foundation beams and forming the beam-making platform. Compared with the prior art, according to the construction method for the beam-making platform providedby the invention, by adopting the steps of pouring the pile caps and forming foundation beams and pouring the foundation beams and forming the beam-making platform, the beam-making platform which isstable and reliable and avoids non-uniform differential settlement can be manufactured, so that the beam-making quality is guaranteed, and the construction method is high in practicality and safe andefficient.

Description

technical field [0001] The invention relates to the technical field of beam field construction, in particular to a construction method for a beam platform and a construction method for a box girder prefabrication field. Background technique [0002] Box girder is a kind of beam in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, which is similar to a box, hence the name. The box girder of reinforced concrete structure is divided into prefabricated box girder and cast-in-place box girder. The box girder combined with the bridge erecting machine prefabricated at an independent site can be erected after the completion of the lower part of the project, which can speed up the progress of the project and save the construction period. There are two main types of common box girders in terms of materials, one is prestressed reinforced concrete box girder, and the other is steel box girder. Among them, the prestressed reinforced concrete box g...
