The production method of concrete block for green
Technical field:
The present invention relates to a kind of concrete block.
Background technology:
Available coagulation cob brick, piece, general structure is closely knit, be difficult for permeable, can only be as uses such as pavement bricks.
Summary of the invention:
The object of the present invention is to provide a kind of good water permeability, can be used as the production method that plant is planted the concrete block for green of carrier use.
Technical solution of the present invention is:
A kind of production method of concrete block for green is characterized in that: comprise the following steps:
(1) dress mould: the concrete that stirs is packed in the mould;
(2) vibration compacting: mould is vibrated, and suppress by press device.
Time of vibration is 3~7 seconds.The compacting degree of depth be in the mould concrete original height 10~30%.The compacting degree of depth be in the mould concrete original height 15~25%.Concrete each composition weight proportioning is in the step (1):
Stone: 400~600 parts
Water: 70~100 parts
Cement: 80~120 parts.
Cobble-stone diameter is 5~20mm.
The upper mould plate is provided with the mould rod vertical with cope match-plate pattern.The length of mould rod is 30~70% of moulding concrete block height.The mould rod has 20~30.
The inventive method uniqueness, easy to operate, high efficiency, the product good water permeability of production, slit suitable planting plant wherein can be widely used as greening carrier, also can be used as pavement brick and uses.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the schematic diagram of production mould of the present invention.
Fig. 2 is the product structure diagrammatic sketch that the present invention produces.
The specific embodiment:
A kind of production method of concrete block for green comprises the following steps:
(1) dress mould: the concrete that stirs is packed in the mould 5, and concrete each composition weight proportioning is:
Stone: 500 parts (or 400,600 parts)
Water: 85 parts (or 70,100 parts)
Cement: 100 parts (or 80,120 parts).
Cobble-stone diameter is 5~20mm (routine 5mm, 13mm, 20mm).
(2) vibration compacting: vibrate 5 seconds (or 3 seconds, 7 seconds) by 3, the 4 pairs of moulds 5 of vibrating device that are contained on die bottom plate 1 and the cope match-plate pattern 2, and suppress by press device 6, the compacting degree of depth is 20% (or 10%, 30%) of concrete original height in the mould.Upper mould plate 2 is provided with the mould rod 7 vertical with cope match-plate pattern 2, makes and forms vertical hole 8 in the moulding concrete block.The length of mould rod 7 is 60% (or 30%, 70%) of moulding concrete block height.Mould rod 7 has 20~30 (20,26,30 of examples).
The slit 9 that the concrete block that forms has mutual perforation and communicates with the external world is provided with a plurality of vertical holes 8 on concrete block top.Vertically the degree of depth in hole 8 is 60% (or 30%, 70%) of concrete block height.
