An assembled pocket grass-planting concrete prefabricated component and construction method

Abstract

The invention discloses an assembled pocket grass planting concrete prefabricated component and a construction method. The prefabricated pocket grass-planting concrete prefabricated component adopts an upper, middle and lower three-layer structure design. The upper and lower layers are filled with grass-planting concrete, and the porosity of the upper layer is greater than that of the lower layer. The middle layer is a pocket-type cavity structure with a built-in planting bag. The overall design of the prefabricated component of the present invention is light on the top and heavy on the bottom, making the structure more stable, and the pocket cavity structure provides space for storing seeds, soil, and plant substrates. The invention can simplify the process, facilitate the construction, shorten the construction period, reduce the difficulty of maintenance in the later stage, and solve technical problems such as difficult on-site preparation of grass planting concrete, unstable structure, and easy erosion of surface soil.

Description

technical field
