[0055] Example 7

[0056] The present embodiment provides a method for assembling an adjustable-size assembled box culvert structure, comprising the following steps:

[0057] Step 1: According to the engineering design requirements, reasonably divide the box culvert into sections and cross-sections, and determine the number of side wall prefabricated tenon joints, convex prefabricated joints and concave prefabricated joints.

[0058] Step 2: Process the steel bars according to the design drawings. During construction, use the slots and positioning tubes of the steel bar processing positioning frame to control the spacing of the steel bar skeleton. Place the processed longitudinal steel bar skeleton into the frame on the channel steel in sequence, and then install and tie the transverse steel bars. After all the processes are completed, further hoist it directly through the gantry crane, and finally complete the tying of the remaining positioning steel bars on the frame.

[0059] Step 3: Assemble the box culvert formwork. On the premise that the thickness of the concrete cover meets the design requirements, the steel frame is hoisted at multiple points, hoisted into the formwork and installed.

[0060] Step 4: The concrete is poured in layers and vibrated with a vibrator to ensure that the upper and lower layers of concrete are uniform. The side wall prefabricated mortise and tenon joints 1, inverted L-shaped end prefabricated joints 2, convex prefabricated joints 3, concave prefabricated joints 4 and L-shaped end prefabricated joints 5 are respectively made.

[0061] Step 5: After the concrete is poured, use a lever to scrape it flat to ensure a smoother surface. Then fill it with steam, gradually increase the temperature from low to high, and keep the temperature constant for 6 hours. Control the speed of heating and cooling. When the strength is guaranteed to ensure that the surface and edges are not damaged, the side formwork can be removed.

[0062] Step 6: After the components meet the lifting requirements, use a gantry to move them to the maintenance area and use automatic spraying and manual watering for maintenance. In winter, steaming shed maintenance can be used.

[0063] Step 7: Arrange transport vehicles to deliver the prefabricated components to the construction site. After site cleaning, leveling and foundation preparation at the construction site, various prefabricated components are hoisted and installed in the order of bottom plate - side wall - top plate using lifting equipment or mechanical equipment, and concrete is filled in the tongue and groove.
