Embodiment

[0027] The ratio of various raw materials is as follows:

[0028] Cement: 16%

[0029] Sludge: 30%

[0030] Gravel: 46%

[0031] Water: 8%

[0032] Among the above raw materials: the sludge has been harmlessly treated in advance, and made into particles with a size of 1-5mm and a moisture content of 40% and sludge sticks with a length of 50mm and a diameter of 10mm; the size of crushed stone is 10-30mm; the cement is selected Aluminate cement with low pH.

[0033] Implementation steps:

[0034] (1) Stir cement, gravel and water first;

[0035] (2) Add granular sludge and fully mix and stir;

[0036] (3) Put the stirred mixed material into the prefabricated mold, insert the sludge stick, and vibrate and smooth it;

[0037] (4) After curing for 10 hours, disassemble the mold

[0038] (5) Continue to maintain for 28 days, and the preparation of the protection materials is completed;

[0039] (6) After paving the protective materials, sow grass seeds in the sludge sticks,...

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

technical field [0001] The invention relates to the disposal and resource utilization of urban sewage, sludge and solid waste in the field of environmental protection, water conservancy projects and municipal projects, and in particular to a preparation method of porous ecological sheathing materials. It is suitable for slope protection projects of rivers and ditches in water conservancy projects and urban greening projects of municipal projects. Background technique [0002] In the slope protection works of rivers and ditches in water conservancy projects and the urban greening projects of municipal engineering, it is an effective method to use concrete slabs for protection, especially for urban flood control, water diversion channels, river revetments, sidewalks, parking lots, etc. In most projects, this method is adopted. However, this kind of protection method is at the cost of damage and deterioration of the natural environment. Not only is there no grass on the surfac...
