Description

Box culvert mould

Technical Field

The utility model relates to a box culvert preparation field, concretely relates to box culvert mould.

Background

The prefabricated middle box culvert is an important internal component of the super-large-diameter road shield tunnel and plays a role in providing a construction channel for a tunnel construction period and providing a traffic lane foundation and a function partition for an operation period. On the basis of the prefabricated box culvert, cast-in-place lane boards are applied to two sides of the box culvert, and the cast-in-place lane boards are combined to form a complete traffic lane.

Because the cast-in-place roadway plate is made of concrete poured by steel bars, the quality of the cast-in-place roadway plate is influenced by the distance between the steel bars. At present, for the construction of a cast-in-place roadway plate, a plurality of reinforcing steel bar connectors are usually sleeved on main ribs of a steel bar cage of a box culvert in advance in the manufacturing process of the prefabricated box culvert, the other end interfaces of the connectors are dug out at corresponding positions respectively after the box culvert is poured, the main reinforcing steel bars of the roadway plate are connected to the interfaces, and then concrete is poured to form the cast-in-place roadway plate.

However, the above construction method has many disadvantages: firstly, when the reinforcing bar connector is sleeved on a main reinforcing bar of a box culvert reinforcing cage, the connecting position of the reinforcing bar connector is usually selected by the experience of a constructor, so that the positioning of the reinforcing bar connector possibly has deviation, the spacing of the reinforcing bars in the subsequent cast-in-place roadway plate construction process has deviation, and the construction quality is influenced; secondly, in order to prevent concrete from permeating the interface of the reinforcing bar connector, a cap is usually arranged at the interface at the other end of the reinforcing bar connector, and during the concrete pouring and vibrating process of the box culvert, the cap of the connector is easy to fall off, so that the concrete permeates the interface, the failure of the individual reinforcing bar connector is caused, and the difficulty is caused to the subsequent construction of the cast-in-place track slab; finally, the excavation of the interface at the other end of the connector is usually performed by means of memory of the connector sleeving position in the preceding step by a constructor, which may have deviation, thereby bringing difficulty to the excavation of the interface and affecting the construction efficiency.
