Precast clamp slot type hollow brick and ecological land ridge

Abstract

The invention discloses a precast clamp slot type hollow brick with low manufacturing cost and simple structure. The hollow brick comprises a brick body; a convex outer clamp slot is arranged on one side of the brick body; and an inward-sinking inner clamp slot is arranged on the other side of the brick body. The invention also discloses an ecological land ridge which comprises an ecological land ridge main body; the ecological land ridge main body is formed by splicing the precast clamp slot type hollow bricks; and plants are grown in the holes of the precast clamp slot type hollow bricks. The precast clamp slot type hollow brick disclosed by the invention is a basic composition unit of the ecological land ridge; the precast clamp slot type hollow bricks are spliced through respective inner clamp slots and outer clamp slots, and the cement mortar is not needed for bonding, thus the material and labor force are saved. Multiple precast clamp slot type hollow bricks are spliced through the clamp slots and built into a complete land ridge according to a lattice wall building method, thus the water permeability of the dry-stone land bridge is maintained while improving the overall stability of the ecological land ridge. Moreover, plants can be grown in the holes of the hollow brick body.

Description

technical field [0001] The present invention relates to a kind of brick, more specifically relates to a kind of prefabricated slot-type hollow brick used for the construction of the ridge of slope conversion project. The invention also relates to an ecological ridge prepared by using prefabricated slot-type hollow bricks. Background technique [0002] "Slope to ladder" is the most basic water and soil conservation engineering measure for the improvement of sloping farmland in the Yangtze River Basin. The "Changzhi" project has always focused on the improvement of slope to ladder, and vigorously implemented the slope to ladder project. The "Three Gorges Follow-up Work Plan" discussed and approved at the executive meeting of the State Council in May 2011 also included "slope conversion" as an important part of the construction of ecological barriers in the Three Gorges reservoir area. Compared with sloping fields, terraced fields have flat ground, good moisture content, high ...

AI Technical Summary

Problems solved by technology

[0003] The main problem is that the cost of "slope conversion" remains high, and the average cost of transforming 1 mu of sloping farmland is as high as 10,000 yuan

Taking the construction of 1m-high stone ridge terraces as an example, the average cost of the stone ridge alone is as high as 4,000 yuan, and it is severely limited by the source of materials and the lack of labor.
