Abstract
The present invention relates to a plant growing type porous concrete spherical block which belongs to a prefabricated part used for civil, traffic and hydraulic engineering. The block is composed of four parts the top parts of which are spherical caps 1 and the lower parts are conical tables 2; the four parts are symmetrically arranged to the layout of a conical center hole 3; the parts among the four conical tables 2 are solid bodies 4. The raw material of the block comprises cement, rubble, mineral additive and a high performance water reducer, and the raw material has the mixing proportion of 150 to 360 kg/m<3> of cement, 1400 to 1800 kg/m<3> of rubble the single grain diameter of which is from 10 to 20mm, 10 to 180 kg/m<3> of mineral additive and 0.2 to 0.3 of water glue ratio; the dosage of the water reducer is 0.5 to 5.0% of the dosage of cementing material. The present invention adopts a stirrer for stirring or pressing or vibrating or tamping and forming. The block is made from porous concrete of high void ratio (20 to 30%), and has high strength and strong erosion resistance. Because the inner part of the concrete block has continuous voids, the present invention has favorable water permeability and ventilation property, and plants of definite root system can be grown in the block.
Description
Technical field
The present invention is the prefabricated component that a kind of building, traffic and river construction are used, and belongs to that civil engineering material makes
Technical field.
Background technology
In the construction of traffic, river construction, present shore protection and road bulkhead tech mainly adopt builds normal concrete or adopts the normal concrete building block to mat formation, can destroy bad borders of local area ecological such as the original soil vegetative cover of the Nature like this, thereby influence the vegeto-animal growth in this zone.Some occasion adopts the trellis concrete segment, filling earth in the square hole of trellis building block, and the sowing grass seeds, but this technology should not be used for the shore protection of SEA LEVEL VARIATION.
Why plant can grow in soil, be that soil has higher voidage (25-30%), soil has gas permeability and moisture capacity simultaneously, suitable acid-base value, required space of plant growing and necessary nutrient can be provided, but resistance of soil is low, a little less than the corrosion resistance, is unfavorable for the stable of shore protection or bank protection.
Summary of the invention
Technical problem: the purpose of this invention is to provide a kind of spherical building block of celluar concrete of energy growing plant, have the continuous space and the voidage of requirement in this building block, make plant can growth in porous concrete building blocks, microorganism and small animal can perch in porous concrete building blocks.
Technical scheme: one of key of planting type porous concrete ball sheet piling technology of preparing be select suitable cementing material, gather materials, mineral additive and chemical admixture and consumption thereof.In plant growing type celluar concrete, the very thin cement mortar layer of one deck because aggregate surface has bondd, therefore, the shape of celluar concrete internal voids depends on to gather materials substantially piles up the shape in formed space, the size of voidage is relevant with the filling extent of size of gathering materials and cement mortar, and the intensity of celluar concrete depends primarily on the intensity of gathering materials and the performance of an agglutination material that gathers materials.So this building block is formed by to be spherical crown, bottom be symmetrical in conical centre's hole arrangement by the part of the frustum of a cone at four tops, the part between four frustums of a cone is real core body.
The present invention adopts 10～20mm simple grain footpath rubble, between 42.5 grades and above portland cement, mineral additive (as ground blast furnace slag, silica flour, superfined flyash), chemical admixture (water-reducing rate is more than 20%) the preparation porous 20～30%.Match ratio: cement 150～360kg/m
3, rubble 1400～1800kg/m
3, mineral additive 10～180kg/m
3, water-cement ratio 0.2～0.3, high-performance water reducing agent are 0.5～5.0% of agglutination material consumption.Adopt agitator to stir compacting or vibration or tamping moulding.
Beneficial effect: plant growing type porous concrete building blocks is the concrete segment that has with the identical voidage of soil, and intensity height, corrosion resistance is strong, because there is continuous gap in concrete segment inside, thereby have good water penetration and gas permeability, the plant of certain root system is grown therein.Plant growing type porous concrete building blocks is used for shore protection or bank protection, the characteristics that not only have traditional concrete revetment or bank protection, and because the cellular concrete surface green plants that growing, both improved the environment of ambient atmosphere, keep green natural landscape again, thereby built up the shore protection or the bank protection of natural, ecological type.Simultaneously, microorganism and small animal live in rough surface of porous concrete building blocks or continuous gap, and be of crucial importance to the protection diversity of organism.
Its voidage of the spherical building block of celluar concrete of pressing the present invention's preparation is between 20～30%, after building block mated formation by engine request, adopt the high-pressure spray gun nutrient matrix that plant growing is necessary to spray into spherical building block inside (can spray into seed simultaneously), can germinate behind the certain hour.
In addition, because block profile of the present invention is spherical, when mating formation, stayed the space between the building block, in the middle of the simultaneously spherical building block circular hole that runs through is arranged, the soil of filling nutrition therein, sowing grass seeds or plantation plant have just formed the ecological revetment with landscape effect after waiting vegetation to reach certain coverage rate.
Building block of the present invention is to have four spheroids to constitute, and compares with single spheroid building block, and production efficiency height, the construction speed of mating formation is fast, has reduced the connector between the building block simultaneously.
