Background

The protection and treatment of side slopes are inevitable key projects in the construction and operation of water conservancy projects such as riverways, lakes, reservoirs and the like. Under the scouring action of wave, rain and the like, the side slope is easy to sink, collapse, slide and other hidden side slope stability hazards and the water and soil loss problem are easily caused, so that scientific and effective protection measures must be taken on the side slope to prevent engineering disasters.

Most of traditional slope protection projects adopt concrete to cast a slope, so that soil can be well fixed, water and soil loss is prevented, and the negative influence on the ecological environment is serious. Therefore, the ecological slope protection device has the double functions of slope protection and ecological greening, concrete pouring protection measures are gradually replaced by the ecological slope protection formed by splicing the bricks, but the ecological slope protection device is poor in overall stability, and poor in water-blocking, anti-skidding and soil-grabbing and migration-stopping effects.

Detailed Description

The details and working process of the ecological slope protection building block for hydraulic engineering provided by the present invention are described in detail below with reference to the accompanying drawings 1-5. The utility model provides an ecological bank protection building block for hydraulic engineering which characterized in that: the building block comprises a building block body 1, a convex buckle 2, a conical rivet 3, a planting cavity 4, a concave clamping groove 5 and a convex stop block 6, wherein the conical rivet 3 is arranged on the back surface of the convex buckle 2; the concave clamping groove 5 is matched with the convex buckle 2; the top and the middle of the building block are provided with convex stop blocks 6, and the front and the back are symmetrically arranged; the planting cavity 4 penetrates through the building block along the thickness direction of the building block, and a protective layer 41 and a nutrition layer 42 are arranged in the planting cavity.

The planar shape of the building block body 1 is a regular hexagon, the shapes of the convex buckle 2 and the concave clamping groove 5 are semicircular, the sizes of the convex buckle and the concave clamping groove are matched with each other, the circle center is the center of the side length of the building block body 1, and the diameter is 1/2 of the side length of the building block body 1. Adjacent building blocks need not mortar and build by laying bricks or stones, only through the inseparable interlock of evagination buckle 2 and indent draw-in groove 5, realize interlocking location, and the concatenation combination forms ecological bank protection wall body each other, can effectively restrict the building block at the not hard up and the deformation that adapts to the slope body that is on a parallel with the slope body direction, and overall stability is good.
