Concrete slope protection building block with drainage and greening functions and construction method thereof

Abstract

The invention discloses a concrete slope protection building block with drainage and greening functions and a construction method thereof. The concrete slope protection building block comprises a building block body, a vegetation growth through groove is formed in the middle of the building block body, third drainage grooves are formed in the periphery of the vegetation growth through groove, twoT-shaped mortises and two T-shaped tenons are arranged on the four side faces of the building block body in total, at least one T-shaped mortise or one T-shaped tenon is arranged on each side face, and a second drainage groove and a first drainage groove which are communicated with the third drainage grooves are sequentially formed in the middle of the surface of each T-shaped mortise and the middle of the surface of each T-shaped tenon. The construction method comprises the following steps of excavating or filling a side slope; slope surface cleaning; paving a gravel cushion layer; paving concrete slope protection building blocks; planting green vegetation; and building a drainage facility connected between the slope bottom concrete blocks and the side ditches. The concrete block has theadvantages of being good in fastening degree, high in adaptability, capable of allowing differential settlement or frost heaving deformation of a slope foundation within a certain range, free of instability damage, small in structural material consumption, attractive, economical and the like.

Description

technical field [0001] The invention relates to a concrete slope protection block and a construction method thereof, in particular to a concrete slope protection block with drainage and greening functions and a construction method thereof. Background technique [0002] During the construction of the project, due to factors such as terrain, soil quality, hydrological conditions along the line, and the control of the elevation along the line, the excavation or filling of the roadbed will inevitably occur, especially when there is a high-filling and deep-excavation road section, often due to The original design of the slope is not stable and corresponding protective measures need to be taken to ensure the stability of the slope. [0003] Among the existing concrete slope protection blocks, the hollow hexagonal block has the advantages of fast construction speed, convenient grass planting and greening in the middle of the hexagonal block, and easy control of construction quality...

Problems solved by technology

[0003] Among the existing concrete slope protection blocks, the hollow hexagonal block has the advantages of fast construction speed, convenient grass planting and greening in the middle of the hexagonal block, and easy control of construction quality. Prefabricated concrete hollow hexagonal blocks are often used as the slope protection structure in slope protection. However, the disadvantage of the current hollow hexagonal block slope protection paved on the slope is that the adjacent slope protection blocks mainly rely on the bonding effect of cement mortar. When the slope foundation is deformed and damaged by uneven settlement or frost heave, it is very easy to cause the slope protection block to be unstable and slump, and the existing concrete slope protection block lacks the consideration of the block itself in terms of slope drainage in the structural design
