Assembly type grass-planted concrete precast block and construction method of ecological bank adopting same

Abstract

The invention discloses an assembly type grass-planted concrete precast block and a construction method of an ecological bank adopting the same. The assembly type grass-planted concrete precast blockis composed of a convex block body and concave block bodies, wherein the convex block body and the concave block bodies are connected into a whole, the convex block body is located in the middle, theplurality of concave block bodies are arranged next to the convex block body, and the convex block body and the concave block bodies are made of ecological concrete with ecological holes; greening soil coverings suitable for the growth of herbaceous plants are laid on the upper surface of the convex block body and the upper surfaces of the concave block bodies respectively, the herbaceous plants take roots on the greening soil coverings and in the convex block body and the concave block bodies; and the concrete precast blocks can be spliced and clamped together. Meanwhile, the invention provides a construction method of the ecological bank adopting the assembly type grass-planted concrete precast block according to the characteristics of the assembly type grass-planted concrete precast block. The assembly type grass-planted concrete precast block has the advantages that the structure is reasonable, the coverage rate of the planted-grass is high and the construction is convenient and rapid; and the assembly type grass-planted concrete precast block can be used for ecological protection of medium and small rivers, and can also be used for ecological protection of channels, lakes, reservoirs and ponds.

Description

Technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a prefabricated grass-planting concrete block and a construction method for ecological bank protection. Background technique [0002] There are many small and medium-sized rivers in our country. Traditional bank protection technology often uses traditional rigid materials such as mortar masonry, cast-in-place concrete and concrete prefabricated blocks for protection. It only focuses on engineering effects such as flood control and safety. The use of some hard materials blocks water growth. The link between the ecological environment and the terrestrial ecological environment destroys the original ecological system of the river, causing the river to lose its role as an ecological corridor. [0003] Ecological river governance is an important manifestation of the construction of water ecological civilization. Aiming at the management of a large number of small and me...

Problems solved by technology

However, it is difficult to solve the following outstanding problems: (1) The cast-in-place planted concrete is easily peeled off in pieces by the erosion of the flood in the river revetment, which affects the ecological effect and aesthetics, destroys the performance of the porous concrete skeleton structure, and causes the river bank slope Instability; (2) The commonly used cast-in-place planted concrete revetment technology has high construction requirements (such as difficulty in controlling the amount of grout and great impact on the operating environment), and requires a very professional construction team, which is not conducive to its practical application and promotion
