Description

Method for greening high and steep rocky slope of mine
Technical Field
The invention relates to the technical field of slope ecological restoration, in particular to a method for greening a mine high and steep rocky slope.
Background
Along with the adjustment of the structure of Chinese economy in the direction from the heavy quantity to the quality improvement quantity, the traditional method for recovering and greening the mine site full-mesh woollen and brownish woollen and brownish can be achieved by innovating and improving a greening scheme according to local conditions.
For a hard geological rock slope, the greening method of the slope mainly comprises two methods: one of the methods is to plant plants only on a slope or under the slope (such as Chinese patent CN104196040B), the slope is only covered by the random growth of climbing plants at the foot of the slope, the time is long, and the effect is not ideal; the other method is that a flower bed is arranged on the slope surface of the side slope, the flower bed is fixed on the slope surface through anchor pulling or cast-in-place and the like, soil is filled in the flower bed (such as Chinese patents CN1570292, CN204305674U, CN207392215U and the like), the construction difficulty is high, the construction cost is high, in addition, the load of the flower bed is concentrated and falls on the slope surface of the side slope, and in addition, rainwater and irrigation water of the flower bed flow down along the slope surface in disorder and overflow, the influence on the stability of the side slope is great.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a method for greening a high and steep rock slope of a mine, which is used for reducing the construction difficulty and the construction cost, solving the problem of natural irrigation of vegetation on the slope surface and simultaneously reducing the influence of load, rainwater and irrigation water on the stability of the slope.
The invention provides a method for greening a mine high and steep rocky side slope, which comprises the following steps:
step S1: putting the side slope into a slope according to the stable slope angle;
step S2: excavating a slope top intercepting drain along the slope top of the side slope, excavating a slope toe drainage ditch along the slope toe of the side slope, excavating a plurality of rows of slope planting grooves on the slope surface between the slope top intercepting drain and the slope toe drainage ditch, wherein the upper end and the lower end of each slope planting groove are respectively connected with the slope top intercepting drain and the slope toe drainage ditch, slots are formed in the slope planting grooves at certain intervals, the outer ends of the slots extend upwards in an inclined manner along the direction away from the side slope, a plurality of rows of slope drainage ditches are excavated on the slope surface between the slope top intercepting drain and the slope toe drainage ditch, overflow ports are formed in the slope top intercepting drain corresponding to the slope drainage ditches, the upper ends of the slope drainage ditches are connected with the overflow ports, and the lower ends of the slope drainage ditches are connected with the slope toe drainage ditches;
step S3: inserting prefabricated partition plates into the slots of the slope planting grooves respectively, wherein the inner ends of the prefabricated partition plates abut against the bottoms of the slope planting grooves, and the prefabricated partition plates are transversely partitioned in the slope planting grooves, so that soil containing grooves are formed between the upper surfaces of the prefabricated partition plates and the slope planting grooves;
step S4: filling planting soil in each soil containing groove, wherein the planting soil filled in the soil containing groove at the top end of the slope planting groove seals the joint of the slope top intercepting drain and the slope planting groove;
step S5: and planting various vegetations on the planting soil in each soil containing groove.
Firstly, a slope planting groove is excavated on the slope, and a row of soil containing grooves are formed on the slope in a mode of installing prefabricated partition plates in the slope planting groove, compared with the traditional mode of directly pouring flower stands on the slope or fixing the flower stands on the slope through anchor rods, the method is more convenient to construct and lower in construction cost, the slope planting grooves are vertically arranged, the load is dispersedly transferred into a slope body from top to bottom through the prefabricated partition plates, the whole stress condition is good, and the influence of the additional load of the flower stands and the planting soil on the slope stability is reduced; secondly, during raining, the rainwater on the mountain flows into the top of the slope intercepting ditch, flow into the domatic escape canal from the overflow mouth of top of the slope intercepting ditch again, row to the toe escape canal of the slope is arranged to the rethread domatic escape canal, can prevent like this that the rainwater from causing the erodeing to domatic, the influence of rainwater to side slope stability has been reduced, and simultaneously, top of the slope intercepting ditch can also be impounded, water in the top of the slope intercepting ditch oozes from the top down along the domatic escape canal, the natural irrigation problem of domatic upward vegetation has been solved, the vegetation survival rate is higher, irrigate the orderly seepage flow of water top-down, can not influence the rock mass at other positions of side slope, it is.
Further, the step a1 is further included between the step S3 and the step S4: and laying geotextile in the soil containing groove. Through laying geotechnological cloth in flourishing soil box, can prevent that the planting soil in the flourishing soil box from the gap loss between prefabricated baffle and the domatic planting groove.
Further, the step B1 is further included between the step S2 and the step S3: and plastic drainage plates are laid along the slope planting grooves and attached to the bottoms of the slope planting grooves. The plastic drainage plate has the effect of guiding seepage water, and the plastic drainage plate is laid at the tank bottom of the slope planting tank, so that the seepage effect of irrigation water can be improved, even if planting soil close to a toe can be well irrigated, and compared with the traditional seepage pipe and the irrigation mode of drip irrigation pipes, the cost of the plastic drainage plate is lower, and the construction is also more convenient.
Further, in the step S1, when the slope is high, the slope is set to be a stepped slope.
Further, in the step S2, the slope planting troughs are arranged in parallel at a distance of 5m to 10 m.
Further, in the step S3, the inclination angle α of the prefabricated partition board is between 10 ° and 45 °.
Further, the vegetation planted in step S5 is creeper.
Further, in step S4, the planting soil is filled by throwing with a guide pipe or spraying with a high pressure machine from top to bottom.
