Abstract

Concave-convex concrete ridge lattice stone masonry slope protection, the slope protection is built on the outside of the embankment formed by mud-filled pipe bags, the concave-convex concrete ridge lattice stone masonry slope protection is composed of concrete ridge lattice and grouting filled between the lattice It is composed of block stones; the roughness rate of the concrete ridge grid is 25%, and the height of its protrusion is between 0.3-0.4 of the thickness of the concrete ridge grid; drainage holes and Expansion joints; a plurality of decompression holes are set on the pouring blocks, and the slope protection has a reduction coefficient of 0.85 to 0.88 for the thickness of the embankment protection surface; and a reduction coefficient of 0.73 to 0.81 for the wave climbing. The thickness of the poured stones is 0.40-0.45m, and the porosity of the drainage holes is between 2.5-5%. The slope protection of the present invention adopts the poured block stone structure, and the wave dissipation effect is similar to that of the dry block stone structure, but the integrity is better, and the ability to resist wind and waves is stronger; moreover, it has the advantages of low cost and convenient construction.

Description

technical field [0001] The invention relates to embankment slope protection, in particular to a concave-convex concrete ridge lattice masonry slope protection. It is suitable for embankment seawalls and embankment slope protection projects along the river and coast. Background technique [0002] With the development of cities, the demand for land is increasing day by day, and enclosing land is an effective method to alleviate the contradiction between land supply and demand, and the scale and intensity of enclosing land are increasing day by day. [0003] The top elevation of the embankment is an important factor affecting the project investment, and the type of slope protection structure facing the water is the key to determine the elevation of the embankment crest. Dike safety is of great significance. Since the founding of the People's Republic of China, the slope protection structure types of seawalls in China have also made great progress along with the construction o...
