Omnidirectional interlocking slope protection building block and lapping interlocking method thereof

Abstract

The invention relates to an omnidirectional interlocking slope protection building block, which comprises a rectangular body and is characterized in that: a pair of upright L-shaped lapping plates of which the notches are back-to-back and face upwards is arranged on the front lateral surface of the rectangular body; a pair of inverted L-shaped lapping plates of which the notches are back-to-back and face downwards is arranged on the back lateral surface of the rectangular body; the two upright L-shaped lapping plates and the two inverted L-shaped lapping plates are symmetrical about the central cross section of the rectangular body; a first groove is formed between vertical lapping sections of the two upright L-shaped lapping plates, and a second groove is formed between vertical lapping sections of the two inverted L-shaped lapping plates; an ecological through hole is formed on the rectangular body; and rope holes are formed on horizontal lapping surfaces of the upright L-shaped lapping plates and horizontal lapping surfaces of the inverted L-shaped lapping plates in the longitudinal direction. Simultaneously, the invention also provides a lapping interlocking method for the omnidirectional interlocking slope protection building block. By the method, an erosion preventing slope protection building block net can be constructed, and the erosion preventing slope protection building block net has high adaptability and erosion resistant capacity, high porosity and water permeability, convenience for construction and low maintenance cost.

Description

Technical field [0001] The invention relates to an omnidirectional interlocking slope protection building block and a lap and interlocking method thereof. Background technique [0002] In order to prevent soil erosion, erosion and erosion, a layer of slope protection and bottom protection pavement should be laid on the bottom and side slopes of natural rivers, lakes, and reservoirs. Commonly used are rigid lined paving structures and flexible lined paving structures. Among them, rigid lined paving structures such as dry block stone, mortar block stone, cast-in-place concrete, etc., have high overall costs, are not easy to plant grass and green, and aquatic life cannot survive. It is ecological, not suitable for frost rise and subsidence, and poor durability; while the existing flexible lining pavement structure has lower cost and better permeability, but it still has many problems such as inability to adapt to large river deformations. [0003] The most commonly used material for ...

Problems solved by technology

Plane interlocking blocks can be locked on the plane, and can lay out a lot of patterns, but they are not interlocked vertically. When the slope protection foundation under the blocks has uneven settlement or frost heaving and thawing When vertically compressed, the blocks tend to sink alone, and the surface of the slope protection is uneven, which will eventually lead to the collapse of the entire slope protection system

Although the existing vertical interlocking blocks are equipped with a locking structure in the vertical direction, which solves the problem that the blocks will sink alone, their locking performance in the plane direction is poor, and when they are used for river revetment, they are greatly affected. The erosion of the water flow will displace and deform, and the measures of filling soil, planting grass, greening and soil stabilization are often used, which increases the project cost
