Problems solved by technology
In addition, these technologies themselves also have some problems: if the all-steel anchor rod is fixed in the borehole with concrete, there is a disadvantage of not being firmly fixed. One of the manifestations is that the diameter of the steel bar is small and checked after being pulled out, and the concrete does not fill the shape of the borehole. It is not cylindrical but elliptical, and the tensile strength of concrete does not meet the specification requirements, but the smaller the diameter of the concrete holding force, the smaller the holding force of the steel bar (diameter 16-32mm); The moisture is quickly absorbed by the rock and soil of the hole wall prematurely, and the water is lost prematurely without subsequent maintenance, resulting in cracks in the concrete, the concrete cannot reach the design strength, and the anchor bolt cannot reach the design pull-out force
This is the fatal flaw of the technology, thus causing the biggest hidden danger in the quality of the project
The third is a series of problems such as low greening rate and high resource consumption. The most critical problem is that the metal mesh fixes the soil quickly and corrodes in the soil. After a few years, the heavy rain washes away the soil and water

Embodiment Construction
[0017] The above purpose is mainly achieved through the following schemes
[0018] 1. Utilize existing plastic production equipment, produce molds according to this component technology, design process formula, manufacture modified plastic series components, and adjust the formula to meet the standard through physical experiments on its strength.
[0019] 2. Apply and test relevant data in engineering, and prepare technical documents such as relevant specifications, standards, and product types.
[0020] 3. Build "three walls" according to the engineering design requirements, pre-embed hooks in the horizontal direction at a height of 2.5 meters, install planting boxes, and place the upper and lower rows in the middle, and the distance between the two boxes is 3-4M. A row of hooks is pre-embedded for every 2.5 meters of elevation Up to the top, at the same time at a distance of 4-5 meters from the wall, the pre-embedded plastic drainage pipe extends 30-50mm from the wall

The invention discloses a building slope ecological support technology, which comprises a modified plastic series component, an assembly process and a vegetation planting and slope protection technology, and is characterized in that a plastic-steel composite anchor bar can be extensively applied on the project treatments of project construction artificial cut slope, natural landscape region, natural slope on the two sides of road and dangerous rock and the like through replacing full-thread steel anchor bar and full-thread plastic anchor bar. Compared with the conventional support technology, the technology can save resources, well protects ecological environment, prolongs the service life of the support project, reduces cost, and realizes the technology renovation of one time slope support.
Description
1. Technical field [0001] The invention relates to a building slope ecological support technology. 2. Background technology [0002] The reinforcement and protection technologies for the retaining and retaining of artificial cut slopes formed by excavation or filling construction in the construction site or surrounding areas in my country are: anchor retaining wall, gravity retaining wall, buttress retaining wall (referred to as "retaining wall") Three walls") bolt (cable), rock shotcrete, slope rate method and other technologies. Materials used: steel bar (rebar), cement, rubble, brick, sand, metal mesh, plastic cloth, etc. In short: "Three Walls", the rock anchor shotcrete support has no vegetation on its surface. The "lattice" type and the slope rate method are to fix the reinforced concrete components on the slope with anchor rods, and then fix the soil (100mm thick) through metal mesh (60×60mm). Due to the application of this kind of technology, most of the slopes hav...
