Abstract

The invention discloses a preparing method of porous ecological revetment material, which comprises the following steps: proceeding non-harmful disposal for sludge; preparing particle sludge and sludge bar; stirring cement, stone, water and particle sludge; adding the stirred composite material into mould; plugging sludge bar; vibrating; moulding; stripping; culturing to obtain the product.

Description

The ecological revetment material of a kind of porousness

Technical field

The present invention relates to useless admittedly disposal recycling, hydro project and the public works of city sewage and sludge of field of environment protection, especially relate to the ecological revetment preparation methods of porousness.Be applicable to the river in the hydro project, the slope protection works of irrigation canals and ditches and the urban greening project of public works etc.

Background technology

In the urban greening project of the river in the hydro project, the slope protection works of irrigation canals and ditches and public works, carrying out revetment with concrete plate is a kind of efficient ways, in the engineerings such as particularly urban flood defence, water-drawing channel, rivers shore protection, walkway, parking lot, major part has adopted this mode.Yet this revetment mode but is to be cost with the destruction of physical environment and deterioration, and not only not even a blade of grass grows on the surface, uses goods and materials such as non-renewable sand, stone, cement also in a large number, and the production cost costliness.

Mud is meant the mud of municipal sewage plant here, and its characteristic is the organic content height, and particle is thin, is cotton-shaped colloidal structure, and viscosity is strong.Along with the develop rapidly of Urbanization in China, the scale that municipal wastewater treatment plant is built is increasing, and quantity is more and more, and the mud generation is huge.Be worth though mud has various recyclings, must consider the objectionable impurities that it contains simultaneously, the risk problem of stacking or landfill, the high cost problem of handling and disposing.Therefore, how safety, economical, scientifically utilize mud to become the research topic that various countries, the world today extremely pay close attention to.Sludge Disposal mainly contains minimizing sanitary landfill, burning, manufacturing fertilizer, makes building materials etc. at present.

Summary of the invention

The objective of the invention is to utilize mud as main raw material(s), but a kind of ecological revetment preparation methods of porousness of saving sandstone, growing plant with low cost is provided.Be rich in organic mud, not only can increase the porosity of revetment material, also can be used as and delay the nutritional need that is placed with the machine grossness foot plant initial stage and supply the plant rhizome to penetrate.

Technical scheme of the present invention is: the ecological revetment material of a kind of porousness is made up of mud, cement, rubble (or cobble), water, and is as follows by the quality proportioning:

Mud: 20%～50%

Cement: 10%～20%

Rubble: 30%～50%

Water: 5%～15%

In above-mentioned starting material: mud passes through harmless treatment in advance, and water ratio 20%～50% is made the granule sludge of size 1～5mm, or length is that 30～100mm diameter is the mud rod of 5～10mm; The rubble size is 10～30mm; Cement is selected the lower aluminate cement of pH value for use.

Preparation process of the present invention:

(1) harmless treatment of in advance mud being fermented, and make granule sludge and mud rod;

(2) by proportioning cement, rubble, water are stirred;

(3) add granular mud, and thorough mixing stirs;

(4) mixing material that stirs is put into prefabricated mould, insert the mud rod, vibrate;

(5) mould is removed in the typing back;

(6) maintenance is 15～30 days, and the revetment material preparation is finished.

The present invention can make arbitrary shape as required, and construction is simple, and greening is convenient.

The present invention utilizes activity of cement effect, is that main raw material is made with rubble and granule sludge.This revetment material has characteristics such as porosity is big, the aqueous vapor permeability is strong, intensity is higher, non-deformability is good, be a kind of more satisfactory greening and view bank protection and pavement construction material, can be widely used in the slope protection works and the engineerings such as walkway, parking lot, agricultural greenhouse and nursery terrace of highway, railway, water conservancy.

The present invention has following characteristics:

(1) adopting mud is main raw material, and scientifically recycling mud reduces the exploitation to natural sandstone, has tangible ecology, economic benefit;

(2) utilize mud to be rich in organic colloid property, improve strainability of the present invention, not only can tackle silt but also can breathe freely by drainage;

(3) adopting acid sludge is raw material, can not only reduce concrete alkalescence, and the slow fertilizer of putting can also be provided, and improves the possibility of plant survival and growth;

(4) seed of plant can be blended directly in the mud rod, also can pave construction back seed or seedling kind in mud rod of the present invention, the plant rhizome can enter soil by the mud rod;

(5) the present invention has that porosity is big, the aqueous vapor permeability strong, ultimate compression strength is than characteristics such as height.

Embodiment

Embodiment:

Various proportion of raw materials are as follows:

Cement: 16%

Mud: 30%

Rubble: 46%

Water: 8%

In above-mentioned starting material: mud passes through harmless treatment in advance, and to make size 1～5mm water ratio be that 40% particle and length are the mud rod of 10mm for the 50mm diameter; The rubble size is 10～30mm; Cement is selected the lower aluminate cement of pH value for use.

Implementation step:

(1) earlier cement, rubble, water are stirred;

(2) add granule sludge, and thorough mixing stirs;

(3) mixing material that stirs is put into prefabricated mould, insert the mud rod, and it is floating to vibrate;

(4) maintenance after 10 hours is dismantled mould

(5) continue maintenance 28 days, the revetment material preparation is finished;

(6) after the revetment material is paved, in the mud rod, broadcast grass seeds, water seasoning, grass seeds growth after several days.

Present embodiment porousness revetment material porosity＞35%, 28 day ultimate compression strength 18MPa.

Claims

1. the ecological revetment material of porousness is characterized in that being made up of mud, cement, rubble (or cobble), water, and is as follows by the quality proportioning: mud 20%～50%, cement 10%～20%, rubble 30%～50%, water 5%～15%.

2. the ecological revetment material of a kind of porousness according to claim 1, it is characterized in that: mud passes through harmless treatment in advance, water ratio 10%～50% is made the granule sludge of size 1～5mm, or length is that 30～200mm diameter is the mud rod of 10～50mm.
