Bank-protecting and pollutant-cleansing combined type ecological building block and construction method

Abstract

The invention relates to a bank-protecting and pollutant-cleansing combined type ecological building block and construction method. The ecological building block provided by the invention is formed by casting sand-free concrete, and has a bottom face and two standing faces; the overall ecological building block is tse(a cyrillic alphabet)-shaped; a side concave groove is arranged at one side of the bottom face, and a side bulging part capable of being chelated in relative to the side concave groove is arranged at a same position at the other side of the bottom face, corresponding to the side concave groove; and a concave groove is arranged at the bottom of a lower bottom face of one standing face, and a bulging part corresponding to the concave groove is arranged at the top of the other standing face of a same ecological building block and can be chelated with the concave groove. The invention overcomes the defects of collapse caused by small size of individual bank-protecting ecological building blocks, and easy loss of soils and plants as well as original soil bodies of rivers and lakes, and the like. The bank-protecting and pollutant-cleansing combined type ecological building block can resist impacts of water waves, prevent flood, and maintain water and soil stable, is not prone to cause the phenomenon of collapse on the bank, can be used for plant planting and cleansing of the pollutants from the bank, can be prefabricated in batch by a factory and has the advantages of low fabrication cost, simplicity for assembly in construction, and great time-saving performance for construction.

Description

technical field [0001] The invention relates to a bank revetment block forming and construction method, in particular to a bank revetment cleaning combined type ecological block and a construction method. Background technique [0002] In order to prevent sand loss or land erosion caused by the water flow of rivers and lakes, stone masonry, concrete slabs, cast-in-place concrete or concrete hollow blocks are commonly used to construct river and lake revetments. The revetments of rivers and lakes built by these components have a neat and beautiful appearance, relatively low construction costs, strong ability to resist wave and water erosion, and good revetment effects. But at the same time, almost all the revetments are hardened, and the pores on the revetments are small or almost non-existent, which is not conducive to the habitat of some aquatic animals, and cannot plant aquatic plants. larger. [0003] Before the present invention, some plant revetment type ecological blo...

Problems solved by technology

However, due to the small size of each of these blocks, they are laid flat along the slope of the river and lake bank during construction, and are pressed on the original river and lake bank soil slope by the gravity of the block and its inner filling soil. The soil and plants in these blocks And the original river and lake bank soil is easy to lose when the river and lake are stormy, resulting in the collapse of the river and lake revetment
