Problems solved by technology

[0004] Aiming at the defects and problems existing in the existing ecological slope protection, the present invention provides a straw fiber stone composite ecological slope protection. The ecological slope protection is not only simple in structure and environmentally friendly, but also can protect the bank slopes on both sides of the river from water and soil loss when impacted by water flow , and has the functions of stabilizing vegetation and facilitating the growth of vegetation, and can protect the bank slope from the erosion of rainwater without affecting the water storage of the bank slope, thereby protecting the ecological system of the river

Embodiment 1

[0027] Such as figure 1 The present embodiment shown provides a kind of straw fiber stone composite ecological slope protection, including ecological slope protection 2 laid on the inclined bank slope 1 on both sides of the river, ecological slope protection 2 includes a plurality of straw fiber stone units 3 assembled and fixed together, straw The fiber stone unit 3 includes a main body block 31 and a shell-shaped greening induction layer 32 sleeved on the main body block 31 and conforming to the shape of the main body block 31 .

[0028] The main body block 31 is a horizontal rectangular parallelepiped porous concrete pouring block, and the porosity of the main body block 31 is 20%. The well-developed space in the main body block provides enough space for the growth of plant roots, and can The pores are filled with soil and fertilizers to provide the necessary nutrients for plant growth.

[0029] Such as Figure 4 , Figure 5 As shown, the four corners of the main body bl...

Embodiment 2

[0038] The difference between embodiment 2 and embodiment 1 is that the main raw materials of the shell-shaped greening induction layer are different.

[0039] Such as figure 2 As shown, the main body block 31 is covered with a shell-shaped greening induction layer 32 that is inherently consistent with the shape of the main body block 31. The shell-shaped greening induction layer 32 is a shell made of straw fiber with a thickness of 2 cm. The shell-shaped greening induction layer 32 is mainly based on Corn stalks are processed as the main raw material. During processing, the corn stalks are first braided, then cellulose, water and other raw materials are added and injected into a mold that matches the main body block 31, and then heated and pressed to form a thickness It is a 2cm fiber shell, which is the shell-shaped greening induction layer 32 of the straw fiber stone unit. The strength of the shell-shaped greening induction layer 32 not only meets the requirements of the s...

Embodiment 3

[0041] Embodiment 3 Compared with Embodiment 1, the embedded parts that are flexibly and fixedly connected together through the connectors are all deeply fixed in the bank slope through anchor rods.

[0042] Such as figure 1 , Figure 8 As shown, after the adjacent straw fiber stone units 3 are flexibly and fixedly connected together by metal binding wires 4 to form the ecological slope protection 2, the embedded parts 313 at the four corners of the straw fiber stone units are deeply fixed on the In the bank slope 1, compared with embodiment 1, the ecological slope protection 2 of the present embodiment is more firmly fixed to the bank slope 1, so that the protection effect of the ecological slope protection 2 on the bank slope 1 is better.

Abstract

The invention discloses a straw fiber stone composite ecological protection slope. The ecological protection slope is laid on inclined bank slopes on the two sides of a river channel. The ecological protection slope comprises a plurality of straw fiber stone units which are assembled and fixed together; and each straw fiber stone unit comprises a concrete pouring main body block which is of a transverse cuboid structure and a housing-shaped surface layer which is fixedly arranged on the main body block in a sleeving mode and is consistent with the main body block in appearance and made of straw fiber materials. The straw fiber stone composite ecological protection slope is simple in structure, the materials are environmentally friendly, the bank slopes on the two sides of the river channelcan be protected against water and soil loss when impacted by water flow, the functions of stabilizing vegetation and facilitating vegetation growth are achieved, the bank slopes can be protected against rainwater scouring under the condition that water storage of the bank slopes is not affected, and therefore the ecological system of a river is protected.

Description

technical field [0001] The invention belongs to the technical field of slope protection, and in particular relates to a straw fiber stone composite ecological slope protection. Background technique [0002] As a large agricultural country, my country produces more than 700 million tons of wheat and corn stalks each year. In traditional agriculture, except for a small amount of wheat and corn stalks after harvesting, they are used for gaskets, feeding livestock, and some are used for composting. They are all burned as fuel or burned directly in the field. During the process of burning straw, it is very easy to ignite the surrounding combustibles, resulting in "burning camp". Once a wheat field fire is triggered, it is often difficult to control, causing economic In addition, the burning of straw will destroy the soil structure, so that the microorganisms on the surface will be burned to death, and the humus and organic matter will be mineralized, resulting in a decline in the q...
