An ecological slope protection structure for ionic rare earth mines

Abstract

The invention relates to an ecological slope protection structure for an ion rare earth mine. The ecological slope protection structure is characterized in that bamboo frames are distributed on an inclined slope surface of a side slope and are pressed into soil; each bamboo frame is prepared from bamboo frame strips in longitudinal and horizontal directions through fixing together, and the bamboo frame strips with upward concave surfaces are distributed on the inclined slope surface of the side slope; through holes are formed in the bamboo frame strips, and drain pipes are distributed at the through holes and inserted into the soil of the inclined slope surface of the side slope; slope base drainage ditches are distributed at the bottom of the inclined slope surface of the side slope, and side drainage ditches are distributed on the upper, left and right edges of the inclined slope surface of the side slope and communicate with the slope base drainage ditches; trees are planted on the step-slope leveled land; bamboo piles are beaten into the inclined slope surface of the side slope, the slope base and the step-slope leveled land respectively; a first section of bamboo joint is reserved at the upper part of each bamboo pile, an ecological planting bag is arranged in the bamboo pile above the first section of bamboo joint, and water seepage holes are formed in the bamboo pile walls; each ecological planting bag is formed by wrapping a grass seed base material into geotechnical cloth. The ecological slope protection structure can be used for preventing and controlling side slope landslide, is low in construction cost, and realizes ecological and environmental protection.

Description

technical field [0001] The invention relates to ecological slope protection technology, in particular to an ecological slope protection structure of ion-type rare earth mines. Background technique [0002] Rare earth is a general term for 17 rare elements including lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, yttrium and scandium. my country's rare earth mines are divided into two types: heavy rare earths and light rare earths. The heavy rare earths are mainly southern ionic rare earths, and the light rare earths are mainly northern rare earths. Southern ionic rare earth ores are rich in medium and heavy rare earth elements such as yttrium, dysprosium, and terbium, and have become important basic materials for modern high-tech and cutting-edge fields such as national defense. They are my country's advantageous mineral resources and strategic resources. [0003] The...

AI Technical Summary

Problems solved by technology

[0008] (1) The amount of concrete and masonry works for slope protection structures such as reinforced concrete anti-slip retaining walls and ecological stone masonry retaining walls is large. The block retaining wall generally adopts the method of mortar block stone, which has many construction procedures and high project cost. , although this type of slope protection is beneficial to slope stability, it cannot solve the problem of soil erosion in rare earth mines

[0009] (2) Anchor cables or anchor rods and concrete frame slope protection require large-scale construction machinery, and rare earth mines are often located in hilly areas with inconvenient transportation, and the transportation workload of equipment and materials is large. The precision of protective construction is high. If the construction precision is not enough, the soil under the frame will be easily deformed and washed away by rainwater, which will increase the possibility of slope instability.

[0010] (3) The cost of box-type cages is relatively high. If the slope is placed at a slope angle or at a certain position on the slope, the slope can be stabilized, but if the slope is not treated, the rainwater will still take away the soil, which is not conducive to the edge. slope stability

The current slope protection structure does not consider the properties of the topsoil of rare earth mines, that is, it has strong water permeability and poor water retention, which is not conducive to the growth of plants; if the water inside and outside the slope is not removed in time during heavy rainfall, it will easily cause water and soil pollution. loss and slippery slope
