I-shaped semi-vertical linkage protection slope building block with open holes

Abstract

The invention discloses an I-shaped semi-vertical linkage protection slope building block with open holes. The building block comprises an I-shaped building block body prefabricated with dry hard concrete materials through a vibration extrusion forming process, and is characterized in that linkage tenons are arranged on the faces, opposite to flanges, in two groove openings formed by the two flanges and a web of the I-shaped building block body; the linkage tenons in the same groove opening are symmetric, the linkage tenons in the different groove openings are arranged vertically, two holes are formed in the web, and the outer sides of the two flanges are each provided with a groove. A protection slope formed by laying the building block has better integrity than a traditional protection slope, wave runup and uplift pressure are lowered through the open holes of a face plate of the building block, and high erosion resistibility is achieved. The building block can adapt to small-amplitude changes of temperature, and is good in frost heaving preventing capacity, high in construction efficiency, and the protection building thickness of the protection slope can be reduced. The building block is durable and overall attractive and elegant, investment is saved, and later running maintenance is convenient.

Description

technical field [0001] The invention discloses an I-shaped perforated semi-vertical interlocking slope protection block, in particular to an I-shaped perforated semi-vertical interlocking slope protection block used in slope protection. Background technique [0002] At present, the traditional forms of slope protection mainly include mortar masonry, dry stone masonry, prefabricated or cast-in-place concrete slabs, and residual asphalt concrete slabs. Among them, I-shaped block slope protection is a relatively common form in slope protection of water conservancy projects in my country. [0003] The main disadvantages of traditional I-shaped slope protection: [0004] (1) The durability of traditional I-shaped slope protection is poor. The traditional I-shaped slope protection has poor adaptability to small-scale deformation of the slope. When the soil quality is poor, the slope subsides, or icing uplifts and expands, the traditional I-shaped slope protection is prone to loc...

[0004] (1) The durability of traditional I-shaped slope protection is poor

The traditional I-shaped slope protection has poor adaptability to small-scale deformation of the slope. When the soil quality is poor, the slope subsides, or icing uplifts and swells, the traditional I-shaped slope protection is prone to local damage or structural instability.

When local damage occurs, the damaged panels are easily washed away by water, resulting in large-scale damage to the slope protection, so its durability is poor

[0005] (2) Traditional I-shaped slope protection is prone to overall damage
