AI Technical Summary

Technical Problem

The existing water drain tank culvert has high investment cost, difficult to reinforce the formwork, slow construction speed, and easy to have quality problems such as running molds, expanding molds, and leaking slurry.

Method used

The cast-in-place water tank culvert is adopted for automated mold frame trolley cast-in-place water tank culverts, convex baffles and concave baffles are used to surround the size of the water tank culverts, and the holes and columns are used to improve the firmness; hollow blocks are placed on the steel bar structure, and concrete solidification is accelerated through the limiting plate, support plate and drying mechanism.

Benefits of technology

It reduces the investment cost and the difficulty of template reinforcement, improves the construction speed, and effectively prevents the occurrence of quality problems, ensuring the stability and sealing of the drain tank culvert.

Abstract

The utility model relates to the technical field of box culvert construction, and discloses an automatic formwork trolley cast-in-situ drainage box culvert which comprises a bottom plate, clamping plates are arranged on the front side and the rear side of the top end of the bottom plate, a plurality of clamping holes are formed in the left side and the right side of each clamping plate, a hollow block is arranged at the top end of the bottom plate, and a concave baffle is arranged on the left side of the outer wall of the hollow block. A convex baffle is arranged on the right side of the outer wall of the hollow block, clamping columns are fixedly connected to the adjacent sides of the convex baffle and the concave baffle and clamped with the clamping holes, a plurality of holes are formed in the front side and the rear side of the hollow block, and limiting plates are arranged on the inner walls of the holes. According to the water drainage box culvert formwork supporting device, through mutual cooperation of the clamping plates, the convex face baffles and the concave face baffles, a formwork needed by a water drainage box culvert can be simply and rapidly supported, and through mutual cooperation of the heater, the cover plate and the flashing board, the solidification speed of the formwork can be increased.
