Abstract

This invention relates to a stereo reinforced earth, characterized in that it arranges the reinforcement in the engineering earth, and the reinforcement is space stereochemical structure. The reinforcement body has great force tolerance, and can exert the best in the earth, improving the bearing capacity of the reinforcement structure and the integrity of the reinforcement body. Said invention is fit for the engineering field such as wall, slope, foundation, bridge abutment.

Description

Stereo reinforcement earth

Technical field

The present invention relates to a kind of civil engineering reinforced earth, particularly a kind of three-dimensional reinforcement pattern.

Background technology

" reinforced earth " at first proposed in 1963 by French engineer Henri Vidal, and it has been widely used in fields such as barricade, side slope, ground, abutment, harbour.Yet the reinforcement that uses in these engineering practices is traditional horizontal arrangement reinforcement.The insufficient strength ideal of its reinforced earth is not given full play to the effect of reinforcement in geotechnological journey.

The content of invention

The object of the present invention is to provide a kind of stereo reinforcement earth, can give full play to the effect of reinforcement in geotechnological journey, improve the intensity of its reinforced earth.

For achieving the above object, the present invention adopts technique scheme:

A kind of stereo reinforcement earth by arranging in the engineering that reinforcement constitutes, is characterized in that the reinforcement of arranging in the described engineering soil is a space multistory structure reinforcement.

Above-mentioned space multistory reinforcement is a lattice space multistory reinforcement.

Above-mentioned described lattice space multistory structure reinforcement is the board-like lattice reinforcement of transverse slat and riser formation lattice or is the sheet-pile lattice reinforcement of plate and post formation lattice or the cylinder fence reinforcement that constitutes fence for cylinder.

Above-mentioned space multistory structure reinforcement is the board-like space multistory structure of band convex body reinforcement.

The above-mentioned board-like space multistory structure of band convex body reinforcement is the one-sided or bilateral vertical plate reinforcement that constitutes of the one-sided of plate or bilateral band raised line or the one-sided or bilateral hollow prism reinforcement that constitutes for the one-sided or bilateral band hollow prism body of plate or the one-sided or bilateral hemispherical reinforcement that constitutes for the one-sided or bilateral band hemisphere of plate or the one-sided or bilateral circular cone reinforcement that constitutes for the one-sided or bilateral band cone of plate, perhaps be the one-sided or bilateral annulus reinforcement of the one-sided of plate or bilateral band dome ring body formation.

The material of above-mentioned reinforcement is steel or steel concrete or geosynthetics polymer.

Above-mentioned geosynthetics polymer is the combination of plastics or rubber and fabric thereof.

The present invention compared with prior art, have following conspicuous outstanding substantive distinguishing features and remarkable advantage: the reinforcement in the reinforced earth provided by the invention is a space multistory structure reinforcement, the reinforcement body structure is stressed rationally, can bring into play the effect of reinforcement in soil to greatest extent: 1, comprehensive friction and effect of contraction between the muscle material and the soil body have been increased, when three-dimensional reinforcement has certain altitude, not only there is the frictional force between the horizontal reinforcement and the soil body in three-dimensional reinforcement, and three-dimensional reinforcement also forms vertical (solid) wall, apply the resistance of a horizontal direction to the soil body, stoped the slippage of the soil body.Under identical external load situation, reduce the consumption of muscle material, or under the situation of same quantity muscle material, improved the bearing capacity of earth structure.2, improved the force-bearing situation of reinforced earth integral body, strengthened stressed continuity between the muscle material, three-dimensional reinforcement is linked to be an integral body to the loose soil body as the collar, thereby has brought into play both actings in conjunction, has strengthened the reinforced earth body globality.Be applicable to engineering fields such as barricade, side slope, ground, abutment, harbour.
