Problems solved by technology

[0002] The existing cast-in-place box girder construction is to build the cast-in-place box girder on the support. This construction method has many risk factors and high construction risk.
Especially in the relatively poor geological conditions of the bridge site, there are more hidden dangers
If the support foundation is not handled properly, it is easy to sink, the light one will cause the beam and slab to crack, and the heavy one may cause the support to be unstable, affecting the construction quality and construction safety

Embodiment Construction

[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0020] The invention provides a supporting component of a cast-in-place box girder.

[0021] The support assembly of the cast-in-place box girder according to the present invention includes: a prefabricated base 10 for a temporary pier, which is a reinforced concrete prefabricated part;

[0022] Such as figure 1 Shown, the present invention is provided with in the mid-span of cast-in-situ box girder and around the permanent buttress of bridge body temporary buttress 20 is set, is used for supporting and strengthening beam body and the permanent buttress of reinforced concrete structure that has built, and , during construction, the cast-in-place box girder construction is carried out with the support system composed of the temporary pier 20 and the beam body 30 . The temporary buttress 20 is fixed vertically on the prefabricated ba...

Abstract

The invention provides a support assembly and a construction method of a cast-in-place box girder. The support assembly of the cast-in-place box girder comprises a temporary buttress prefabricated base and a temporary buttress, wherein the temporary buttress prefabricated base is a reinforced concrete prefabricated member, and the temporary buttress is fixedly arranged on the temporary buttress prefabricated base. The construction method of the cast-in-place box girder comprises the following steps of: treating a temporary buttress foundation: pre-treating the ground for paving the temporary buttress prefabricated base to be the temporary buttress foundation; setting up the temporary buttress prefabricated base with a reinforced concrete structure on the temporary buttress foundation and pre-pressing and treating on the temporary buttress foundation after the temporary buttress prefabricated base is set up; mounting the temporary buttress on the temporary buttress prefabricated base; and mounting a sequined beret on the temporary buttress. The invention reduces the engineering cost and is beneficial to ensuring the engineering quality.

Description

technical field [0001] The invention relates to the field of construction, and more specifically, to a support component of a cast-in-place box girder and a construction method of the cast-in-place box girder. Background technique [0002] The existing cast-in-place box girder construction is to construct the cast-in-place box girder on the support. This construction method has many risk factors and high construction risk. Especially in areas where the geological conditions of the bridge site are relatively poor, there are more hidden dangers. If the support foundation is not handled properly, it is easy to sink. In the light case, the beam and slab will crack, and in the heavy case, the support may be unstable, which will affect the construction quality and construction safety. Contents of the invention [0003] The invention aims to provide a support component of a cast-in-place box girder and a construction method of a cast-in-place box girder capable of ensuring the s...
