Greening retaining wall building block and method for constructing retaining wall with building block

Abstract

The invention discloses a greening retaining wall building block which comprises an opening body. The body consists of a base plate and a semi-surrounding structure on the base plate, wherein the semi-surrounding structure is formed from two side walls and a front wall which are connected into a whole, and the rear end of the side wall flanges outwards to form external flanging which outreaches the outer boundary of the side wall of the semi-surrounding structure at the same side. The invention also discloses a method for constructing a retaining wall with building blocks. In the method, the building blocks are interlaced and stacked up, and the front wall of building blocks at the same layer and flanging in occluding connection form a transversal S-shaped continuous closing retaining wall which can prevent soil at the wall back from running off. An open structure formed from a greening groove at the middle of the wall and filled soil at the wall back is provided and is in communication with a greening groove at an open side wall of building blocks at the upper layer, so the retaining wall can provide sufficient thickness of cultivation soil for greening plant cover and continuously provide capillary water or nutritive substances. Therefore, favorable greening conditions are provided for steep retaining wall to create better ecological effects.

Description

technical field [0001] The invention relates to the field of civil construction engineering, in particular to an ecological retaining wall block. Background technique [0002] At present, in the construction of construction, transportation, landscape and water conservancy projects, a large number of technical problems of slope support are often involved. With the increasing awareness of environmental protection and ecological protection, the greening technology of masonry retaining structures such as traditional concrete and mortar block rubble has attracted more and more attention, and great progress has been made. However, for steep slopes, because the slope rate is restricted by the terrain, the masonry retaining wall is still the main body of the slope toe protection "whitening", and the greening treatment is very difficult. Therefore, it is very important how to make the steep slope rate protection project leave a "breathable" green space for the rock slope. [0003] ...

AI Technical Summary

Problems solved by technology

However, the service life of the steel gabion is limited, and the cost of the galvanized steel gabion technology is quite expensive according to my country's national conditions.

[0005] On December 30, 2004, Japan Okasan Libigu Co., Ltd. proposed a "reinforced soil retaining wall with slope-fixing anchor plate" (utility model patent number: 200420075547), but the anchor plate does not have the characteristics of greening

[0008] On June 30, 2006, I proposed "a greenable ecological retaining wall" (utility model patent ZL 2006 20105365.1), which is mainly used for greening the excavated slope retaining wall. This structure has good safety and durability, but the slope protection Masonry traces need to be further optimized

[0009] On September 3, 2007, Cheng Weiguo proposed "a planting-type soil retaining block" (invention patent number: CN200710121284.X), which is characterized in that the front end is provided with planting long holes that run through the top and bottom surfaces and extend along the left and right directions of the block. As well as L-shaped undercuts, the L-shaped undercuts on two adjacent retaining blocks on the upper floor are spliced ​​to form an overall concave structure, and there is a small vegetation hole in the block below for greening, but due to the size limitation of the vegetation hole, according to the implementation situation , the greening effect is still not ideal

However, this anti-slip measure has been widely used in current projects, and the durability of the connecting parts is the key to the technology, and the cost is relatively expensive

[0011] In Europe, America and Japan, there are currently many protective technologies that combine support and greening, such as the Japanese "Gio" ecological retaining wall protected by international patent technology, the Italian MACCAFERRI ecological retaining wall, the American SUREBLOCK ecological block, etc., but The cost of materials is relatively high, and the cost is expensive
