A prefabricated concrete drainage ditch construction auxiliary device and construction method

Abstract

The invention discloses a prefabricated concrete drainage ditch construction auxiliary device and a construction method. The prefabricated concrete drainage ditch construction auxiliary device includes a frame, an alignment device, a front support roller and two coaxial rear support rollers, and the alignment device It includes the first alignment oil cylinder, the second alignment oil cylinder, the third alignment oil cylinder and two alignment plates. The two alignment plates are respectively arranged on the left and right sides of the front support roller. The two ends of the two alignment plates are respectively Located on the front and rear sides of the front support roller. The construction method of the precast concrete drainage ditch of the present invention adopts the construction auxiliary device of the precast concrete drainage ditch of the present invention. The invention aligns the concrete rectangular grooves while laying them during construction, so that the concrete rectangular grooves can be positioned one by one, so that the joints of adjacent concrete rectangular grooves are smaller, avoiding the use of concrete to repair seams, and the construction efficiency is high. The cavity of the groove can be well connected, and the drainage effect is good.

Description

Technical field [0001] The present invention relates to a prefabricated concrete drainage groove construction aid and construction method. Background technique [0002] The existing drainage grooves have been constructed by prefabricated concrete rectangles. When construction, the drainage groove is first excavated, and then the preformed concrete rectangle slots are placed in the drain, and then apply water seal at the seam of the concrete rectangle. Glue, followed by the outer backfill of the concrete rectangle. When the concrete rectangle tank is placed, the concrete rectangular groove is placed in the bottom of the drainage ditch due to the operation of the drainage ditch, and it is difficult for the concrete rectangle slot to be positive, and there is no positive place. The concrete is required, due to the long curing time, affecting the construction efficiency, and the cavity of the concrete rectangular groove cannot be well docked, affect the drainage effect. Inventive co...

AI Technical Summary

Problems solved by technology

When laying the concrete rectangular groove, it is difficult to align the concrete rectangular groove during operation due to manual operation on the top of the drainage ditch to lay the concrete rectangular groove at the bottom of the drainage ditch. Concrete needs to be used to fill the joints. Due to the long curing time of concrete, the construction efficiency is affected, and the cavity of the concrete rectangular groove cannot be well connected, which affects the drainage effect
