Example Embodiment

[0032] Example 1

[0033] Such as Figure 1 to Figure 2 As shown, a method for slope protection based on geocells and fibrous clay mixture according to specific embodiments of the present invention includes the following steps:

[0034] (1) Flatten the slope surface, remove the larger raised rocks from the slope surface, and spray the slope surface to moisten the slope surface. The slope is suitable for weathering with a slope ratio of not steeper than 1:0.75 and above strong weathering Or soil slope.

[0035] (2) Use bamboo nails to fix the geocell on the smooth slope surface, which requires leveling. The geocell material is a three-dimensional mesh cell made of reinforced high-density polyethylene HDPE sheet material through high-strength welding. The cell height is 20mm, the cell sheet thickness is 0.95~1.05mm, and the cell has a single hole area. 50~100cm 2 .

[0036] (3) Clay is made on-site. Clay soil generally requires high viscosity. After taking the clay, it is rolled and ...

Example Embodiment

[0041] Example 2

[0042] A slope protection method based on geocells and fiber-clay mixtures. This method is suitable for special soils, such as expansive soil slopes, red clay slopes, etc. The slope surface should be placed in the slope soil under normal working conditions Physical fitness is naturally stable.

[0043] The difference between Example 2 and Example 1 is that in step (4), the thickness of the mixture paving is ≥ 15 cm. The reason is that for special soils, the direct effects of rain, atmosphere, and sunlight on the slope must be cut off, and the paving thickness of the mixture should be increased appropriately.

[0044] The slope protection method based on the geocell and fiber clay mixture of the present invention, through the above steps, effectively exerts the characteristics of the cohesive soil with water mixing and drying strength, the fiber tensile reinforcement, and the geocell skeleton function, combining the three Together, it avoids dry knots and cracks i...

Abstract

The invention discloses a slope protection method and structure based on an earthwork standard room and a mixture of fiber and clay. The slop protection method comprises the steps that 1 the slope plane of the slope is leveled, and the earthwork standard room is paved on the slope plane; 2 the clay is crushed, then polypropylene fiber, fertilizer and water are added, and stirring is conducted till the mixed materials are in a liquid plastic state; 3 the mixed materials are paved on the slope plane of the slope and is floated; 4 grass seed is sown on the slope plane in a spraying mode, a protection geomembrane is covered, and then artificial protection is conducted. The slope protection method and structure based on the earthwork standard room and the mixture of fiber and clay have the advantages that multiple functions of anti-washing, anti-infiltrating, conserving water, keeping warm, facilitating the growth of plants and the like are possessed, the slope plane can be protected from being eroding and infiltrating of rain before a turf is formed, and the purposes of strengthening the slope and beautifying the environment are achieved.

Description

technical field [0001] The invention relates to the field of geotechnical engineering slope protection, in particular to a slope protection method and structure based on geotechnical cell and fiber clay mixture. Background technique [0002] The image of "ten slides and nine waters" shows that water is an important factor for slope damage. The effect of water on slopes is generally divided into surface water and groundwater. The scouring and splashing of surface water makes the surface water and soil loss serious, and the shallow layer slips and peels off. In addition to the characteristics of suddenness, fast speed, and large number of small shallow slopes In addition to bringing danger to people's lives, property, and travel convenience, shallow small landslides are likely to cause deep instability of large slopes through slip-traction; surface water infiltration forms groundwater, which increases soil weight and The osmotic pressure will lead to the increase of the slidi...
