Embodiment 1

[0021] Embodiment one: referring to accompanying drawing, this vegetation ecological concrete prefabricated block is a multi-layer planting base material, is made of the top layer of culture medium layer 4 suitable for vegetation growth, the upper porous concrete layer 3 suitable for vegetation root system penetration, and the layer suitable for vegetation root system growth. The middle culture medium layer 2 and the lower porous concrete layer 1 suitable for the penetration of vegetation roots constitute a prefabricated block of four-layer structure. The thicknesses of the four layers of the above-mentioned prefabricated block are respectively: the top culture medium layer 4 is 3mm, the upper porous concrete layer 3 is 5cm, the middle waste brick medium mixed layer 2 is 5mm, and the lower porous concrete layer 1 is 5cm; the prefabricated length and width 20cm respectively. The surrounding wall of the prefabricated block has a bonded and strengthened structure layer composed o...

Embodiment 2

[0026] Embodiment 2: See also the accompanying drawings. This embodiment is basically the same as the above-mentioned embodiment, the difference lies in the size of the prefabricated block and the ratio of raw materials. In this embodiment, the thicknesses of the four layers of the prefabricated block are respectively: the top culture medium layer 4 8mm, the upper porous concrete layer 3 is 8cm, the medium culture medium mixing layer 6 is 15mm, and the lower porous concrete layer 1 is 8cm; the prefabricated length and width are respectively 30cm, and the wall cement thin layer 7 thickness is 4mm.

[0027] The raw materials of the upper and lower porous concrete layers 3 and 1 are proportioned by weight as follows: aggregate 100g, cement 65g, slag micropowder 115g, water 500g, and water reducer 55g.

[0028] The raw material composition and weight ratio of the medium medium layer 6 are: 100g of peat, 20-30g of grass clippings, and 2-3g of additives.

[0029] The raw material co...

Abstract

The invention relates to a plant ecological concrete precast block and the preparing method. The plant ecological concrete precast block comprises the following objects: culture medium layer suitable for plant growing, the top porous concrete layer suitable for plant root getting through, the middle mixing layer of waste masonry suitable for plant root growing and lower porous concrete layer suitable for plant root getting through. The preparing steps are: óƒ preparing two up and lower porous concrete layer of same size; ó embedding culture medium on the lower porous concrete soil layer, covering the middle culture medium with prepared upper porous concrete soil layer, sealing the round with flat cement; ó� curing for 3-4 days; óœ covering the precast block with top culture medium. The precast block is embedded on the bank, about 14-20 days later, the grass will grows out, the grass root gets through the upper layer, middle layer and lower layer and enters into the outer soil for greening and water and soil conservation function. The laying is convenient and can carry out industrial production.

Description

technical field [0001] The invention relates to an ecological concrete, in particular to a plant ecological concrete prefabricated block and a preparation method thereof. Background technique [0002] Research on ecological concrete started earlier in foreign countries than in China, such as Japan and the Netherlands. Japan, in particular, is at the leading level in this regard. As early as ten years ago, Japan has already started the research and practice of ecological concrete. Especially in recent years, environmental protection and personal safety have attracted more attention, and the application of ecological concrete technology has become the focus. The greening technology of ecological concrete mainly has three aspects: (1) layer and wall; (2) special space of the road; (3) direct greening of concrete. [0003] Ecological concrete technology has been used in Japan for greening of urban residences, greening of slope protection surfaces on both sides of roads, green...
