Description

Technical Field

[0001] The utility model relates to the technical field of curbstone backrest construction, in particular to a curbstone backrest concrete construction device. Background Art

[0002] The purpose of the curbstone backrest is to prevent the curbstone from being displaced by external forces and to ensure that the curbstone is straight as a whole. During the construction process, it is usually necessary to lay out the lines after the municipal road base water-stabilized construction is completed, remove the water-stabilized construction, and install the curbstone before casting the concrete backrest. However, this will waste a lot of water-stabilized materials. If the curbstone is installed and the concrete backrest is constructed before the water-stabilized construction, the large-scale mechanical rolling during the water-stabilized construction process cannot ensure that the curbstone is not displaced by external forces, which will affect the appearance and physical quality of the curbstone.

[0003] The method of making a curbstone backrest is usually to make a backrest on the back of the curbstone after the curbstone is installed. The backrest has poor integration with the curbstone, and the appearance quality is poor after molding. It is easily affected by external forces and squeezed, causing the curbstone to be not straight.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
