Problems solved by technology

However, bolts are used between the prefabricated driveway slab and the middle box culvert, the curved slab and the middle box culvert, and the driveway slab and the curved slab. tends to deflect, causing loose bolts or cracks at the interface between the driveway slab and the middle box culvert
[0004] To sum up, both the cast-in-place structure and the side box culvert of the prefabricated structure have certain construction defects, and there is no relatively complete technical plan disclosed

Abstract

The invention discloses a side box culvert cast-in-place construction formwork and a construction method. The formwork comprises a formwork system, a contracting and supporting mechanism, a walking mechanism, a main beam connecting the contracting and supporting mechanism with the walking mechanism and a portal system, wherein the contracting and supporting moving system controls the contracting and opening of the formwork system and the movement of a formwork in the extending direction of a tunnel, and the portal system provides power and guidance for movement of the formwork system in the extending direction of the tunnel. Compared with a traditional side box culvert construction method, the method has the advantages that hanging pre-buried holes do not need to be reserved, the procedures are reduced, the hanging arrangement of a front gantry frame system does not influence the advance steel bar binding procedure in the next working section, the connection among the procedures is facilitated, and the construction period is shortened.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling, in particular to a cast-in-place construction formwork for side box culverts and a construction method thereof. Background technique [0002] During the construction of large-diameter shields, in order to facilitate segment transportation, the bottom is designed in the form of a box culvert when designing the internal structure. During construction, segment vehicles and material transport vehicles are transported synchronously on the surface of the assembled box culvert, and other internal structures can be constructed synchronously without interfering with each other, thus saving the construction period and creating convenient construction conditions. [0003] General box culverts include intermediate prefabricated box culverts and side box culverts. Side box culverts are divided into cast-in-situ structures and prefabricated structures. Regardless of the structure, the middle prefabric...
