Title:
CONCRETE POURING CONSTRUCTION METHOD FOR EDGE PORTION OF ROAD BASE LAYER
Document Type and Number:
WIPO Patent Application WO/2023/015984
Kind Code:
A1
Abstract:
The present invention relates to a concrete pouring construction method for an edge portion of a road base layer, and relates to the technical field of municipal engineering road construction. The method comprises the following steps: loosening soil after a base groove is excavated; reserving formwork belts and compacting the base groove between the formwork belts; reinforcing and reserving a pipeline between the formwork belts in the base groove; fixing a steel mold onto the formwork belts; performing leveling by means of a leveling device after the concrete is poured; and filling the formwork belts to be connected to the road after the steel mold is removed. According to the present invention, by arranging the steel mold to enclose the base groove to form a mold cavity, concrete leakage is reduced, such that the steel mold is separated from the concrete in a knocking manner, such that the steel mold can be used multiple times, thereby achieving the advantage of saving resources which are used in the pouring of the edge of the road base layer.
