Embodiment Construction

[0051] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0052] see figure 1 , figure 2 , image 3 , Convexity 4, Concave-convex concrete ridge sash masonry slope protection 3 is composed of concrete ridge sash 1 and poured block stone 2 filled between the sash 1; the roughening rate of concrete ridge sash 1 is 25%, and its convex The rising height is between 0.3-0.4 of the thickness of the concrete ridge 2; drainage holes 11 and expansion joints 12 are arranged on the concrete ridge grid 1 along the radial direction of the embankment; The decompression hole 21, the slope protection has a reduction coefficient of 0.85-0.88 to the thickness of the embankment protection surface, and a reduction coefficient of 0.73-0.81 to the wave climbing.

[0053] In the present invention, the thickness of the poure...

Abstract

A concavo-convex grouting revetment is built on the outer side of an embankment consisting of mud-filled bags. The concavo-convex grouting revetment consists of grouting frame grids and grouting rocks filled among the frame grids, wherein the grouting frame grids has a roughness addition rate of 25% and a protrusive height of 0.3 to 0.4 the thickness of the grouting rocks; drain holes and shrinkage joints are arranged on the grouting frame grids along the radial direction of the embankment; a plurality of decompressing holes are arranged on the grouting rocks; and the revetment has a reduction coefficient to the protection thickness of the embankment of 0.85 to 0.88 and a reduction coefficient to wave run-up of 0.73 to 0.81. The grouting rock has a thickness of 0.40 to 0.45 m, and the drain holes have a porosity of 2.5 to 5%. By adopting the grouting rock structure, the inventive revetment has a wave-damping effect similar to that of dry rock structure and has the advantages of better integrity, stronger wave / wind resistance, low construction 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...
