Problems solved by technology

[0007] During the use of existing slope protection materials, there is still a problem that river water can still enter the soil through infiltration, resulting in soil dissolution. The present invention provides a new and environmentally friendly slope protection material and its preparation method. The raw materials used are simple, and after After specific pretreatment, it is pressed into slope protection bricks and used on river slopes and / or channels in plain river network areas to achieve effective slope protection, improve the ecological water conservancy environment in plain river network areas, effectively improve the self-purification capacity of water bodies and The effect of preventing embankment slope hydraulic erosion; at the same time, the invention provides the slope protection material preparation device, and the structure is reasonable

Embodiment 1

[0077] A kind of slope protection material is provided in the present embodiment, and it is prepared by the raw material of following weight part:

[0078] 30 parts of cement, 18 parts of fermented plant stalks, 2 parts of foaming agent, 50 parts of water; in the present embodiment, a feeding batch operation mode is adopted, and the pretreated plant stalks (with a particle size of 3 to 8 mm) and The inoculated sludge (the inoculum amount is 30% of the mass of the plant straw) is mixed evenly and sealed in a sealed mixing tank 1 for dry anaerobic fermentation. The fermentation temperature is controlled at 20°C to 50°C, and the fermentation time is 1 day. . Fermentation produced 375 mg / g of acetic acid with a carboxyl content of 78.95%.

[0079] Utilize the equipment among the embodiment 1 to prepare above-mentioned slope protection material, specifically comprise the following steps:

[0080] 1) Preparation of lightweight porous structure cement

[0081] Foaming agent and ce...

Embodiment 2

[0089] A kind of slope protection material is provided in the present embodiment, and it is prepared by the raw material of following weight part:

[0090] 40 parts of cement, 10 parts of fermented plant straw, 10 parts of foaming agent, 40 parts of water;

[0091]In this embodiment, the batch operation mode of feeding at one time is adopted, and the pretreated plant stalks (with a particle size of 3-8mm) and the inoculation sludge (the inoculum amount is 30% of the mass of the plant stalks) are evenly mixed and sealed in a sealed mixing tank 1 , dry anaerobic fermentation is carried out, the fermentation temperature is controlled at 20°C to 50°C, and the fermentation time is 3 days. Fermentation yielded 425 mg / g with a carboxyl content of 78.95%.

[0092] Utilize the equipment among the embodiment 1 to prepare above-mentioned slope protection material, specifically comprise the following steps:

[0093] 1) Preparation of lightweight porous structure cement

[0094] Foaming...

Embodiment 3

[0102] Now for the plain river network area, a certain river section uses the slope protection material produced in the present invention to carry out slope care, according to figure 2 In this way, the slope protection material is laid on the river bank slope. Specific steps are as follows:

[0103] 1. Leveling the slope of the river bank 9;

[0104] 2. Concrete structure cushion 8 is poured on the bottom surface of the river channel;

[0105] 3, start from the concrete structure cushion 8 on the bottom surface of the river, gradually carry out close laying to the riverbank slope 9 top, utilize the stainless steel plate 7 to fix the position of each piece of slope protection material 6.

[0106] The main pollutant indicators in the river water body are COD, ammonia nitrogen, total nitrogen and total phosphorus. After the slope protection material provided in the present invention is laid, a biofilm is formed on the surface of the slope protection material. The content of w...

Abstract

The invention relates to a slope protection material and its preparation method, application and production equipment, belonging to the field of new materials. The slope protection material is prepared from cement, fermented plant straw and foaming agent. The raw materials used are simple. After specific pretreatment, they are pressed into slope protection bricks and used for river slopes in plain river network areas. And / or river course, can achieve effective slope protection, improve the ecological water conservancy environment in the plain river network area, effectively improve the self-purification ability of water body and prevent the effect of embankment hydraulic erosion; at the same time, the invention provides the slope protection material preparation device, the structure is reasonable.

Description

technical field [0001] The invention belongs to the field of new materials, more specifically, relates to a novel and environmentally friendly slope protection material and its preparation method, application and production equipment. Background technique [0002] In the plain river network area, due to the low water exchange rate of the river channel and the soil quality around the river is mainly loose and soft soil, the environmental capacity of the river channel is low and the bank slope erosion phenomenon is frequent. In particular, during the dry season, the main water quality indicators showed a clear upward trend. In recent years, ecological slope protection, as an important research direction of watershed environmental governance, has also received more and more attention. Ecological slope protection can prevent soil erosion, reduce slope pore water pressure, intercept rainfall, weaken splash erosion, and control soil loss; it can improve environmental functions an...
