Problems solved by technology

But in actual use, hollow hexagonal bricks use their weight to achieve the caisson effect and partition effect to prevent the planting soil from sliding down. Due to their heavy weight, it is inconvenient to transport upwards, troublesome to manufacture and high in cost, so it has its limitations.
The ecological bag or planting bag also has a large amount due to the thickness of the planting soil in the frame reaching 30cm-40cm, which has the disadvantages of inconvenient upward transportation, high cost of filling the bag and the bag itself, affecting the germination rate and survival rate, and cannot effectively protect concrete cracks
Geocell soil consolidation + three-dimensional net spraying adopts partition soil consolidation and bonding surface consolidation, but due to the large cell size, generally around 1.5m, soil planting on high and steep slopes is easy to be affected by the degree of compaction. Insufficient and slippery, and at the same time, after the binder of the sprayed material loses its viscosity for a long time, it is easy to be washed away by slope runoff or strong rainwater and high-pressure jet maintenance water, especially when non-cohesive soil is used (or no binder is added) , although there is a three-dimensional net to prevent erosion, it is still prone to water and soil erosion and the voiding of the upper planting soil, and it is not suitable for planting shrubs in the framework of the concrete closed slope, because the roots of the plants are shallow and cannot resist wind.
Because the geogrid is used to reinforce the soil, the cost of backfilling is high and slow, and the degree of compaction is only about 80%, and the geogrid that cannot adapt to the bottom and slope of the grid is used. Concrete cover or rock surface is usually used and is uneven. The soil planting part without grid reinforcement on the bottom layer is generally easy to slide down and become compacted when the degree of compaction is generally low, resulting in voids inside the frame or skeleton. Plants in the upper part are not easy to survive

specific Embodiment approach

[0045] A plant measure method for slope protection of concrete frame and masonry rubble skeleton, the steps of which are:

[0046] a. Clean up the debris on the slope surface, the concrete scum on the slope surface and the facade under the concrete beam.

[0047] b. To extend the original drainage pipe on the concrete slope, drill two holes with a diameter of ∮8mm at a position 10cm-30cm deep from the outer plane of the upper geogrid on the lower wall of the extended pipe.

[0048] c. Drill installation holes for geogrid anchor rods perpendicular to the lower facade of the frame, and install the anchor rods with anchor mortar after clearing the holes.

[0049] The diameter of the grid hole is 2mm-3mm larger than that of the anchor rod, and the anchor rod can be directly drilled from the grid hole to avoid the inaccurate positioning of the first planted anchor rod and speed up the progress.

[0050] The anchor rod is made of ribbed threaded steel bars, and the length of the an...

Abstract

The invention discloses a plant measure method for slope protection of concrete frame and masonry rubble skeleton. Double or multi-layer geotechnical grids capable of bearing the gravity of planting soil are arranged in the inner space of concrete frame slope protection, and the bottom grid The supporting plate is installed in the gap between the grid surface and the slope surface, and the lower two layers of geogrid are properly dislocated up and down to limit the outward movement of the supporting plate, and then the construction method of guest soil spraying is carried out in the geogrid, that is, the planting soil passes through the geogrid The horizontal grid strips and supporting plates can achieve the purpose of soil stabilization, and solve the problem of voids caused by the large local gap between the slope surface and the bottom surface of the underlying geogrid and the internal soil is not dense. Through this method, the slope protection of the concrete frame and the mortar-laying stone skeleton The middle planting soil is easy to be washed by water flow and the slope part where the planting soil is easy to slip and lose water and nutrients is easy to carry out ecological treatment, with less water and soil loss, high plant germination rate and survival rate, long survival time, good effect, and little environmental impact. Strong resistance to expansion and shrinkage damage, and strong resistance to freezing erosion.

Description

technical field [0001] The invention belongs to the field of water and soil conservation, and relates to a slope vegetation measure method for slope protection. In particular, it relates to a method of greening plant measures for slope protection with a concrete frame and a masonry rubble skeleton. Less water and soil erosion, simple and practical, high plant germination rate and survival rate, long survival time, good effect, small environmental impact, strong resistance to expansion and shrinkage damage, strong resistance to freezing erosion, low investment, less loss of spraying materials, and labor intensity of workers Low, short construction period. Background technique [0002] At present, in water conservancy and hydropower, highways, railways, port and shipping transportation, mining and other industries, a large number of concrete frames and mortar rubble skeletons are used to protect slopes. Hollow hexagonal bricks are used to consolidate soil and ecological bags ...
