Problems solved by technology

High and steep rocky slopes have always been a difficult point in disaster management and greening. There are small cracks and joints in some parts of the quartzite in the treatment area. High and steep rocky slopes have always been difficult in disaster management and greening. The practice of perforating and backfilling planting soil on limestone slopes has achieved good results. Due to its lithological characteristics, the water in the rocks is less conserved. After greening, it mainly depends on natural precipitation and rock crevice water. In areas with little water content, the conventional 150mm caliber is difficult to guarantee the survival rate of planted green plants

Embodiment 1

[0020] A greening method for high and steep slopes of quartzite in dry and rainless areas, such as figure 1 shown. Described method is specifically as follows:

[0021] 1) Drill horizontally on the slope with a borehole of 100 mm in diameter, such as figure 2 shown.

[0022] 2) Drill a second hole with a diameter of 100mm at the bottom left of the first hole 80mm from the edge of the first hole, that is, the center point of the second hole is 80mm from the edge of the first hole;

[0023] 3) On the right side of the second hole, drill the third hole at a distance of 80mm from the edge of the first hole and the second hole, and the diameter of the drill bit used is 100mm, that is, the center point of the third hole is 80mm away from the edge of the second hole. The distance between the edges of the first hole and the second hole is equal, and both are 80mm, and the centers of the three holes are connected to form an equilateral triangle, such as image 3 shown;

Embodiment 2

[0026] A method for afforesting high and steep quartzite slopes in dry and rainless areas, the method is specifically as follows:

[0027] 1) Drill horizontally with a 100mm borehole on the slope.

[0028] 2) Drill a second hole with a diameter of 100mm at the bottom left of the first hole 90mm from the edge of the first hole, that is, the center point of the second hole is 90mm from the edge of the first hole;

[0029] 3) On the right side of the second hole, drill the third hole at a distance of 90mm from the edge of the first hole and the second hole, and the diameter of the drill bit used is 100mm, that is, the center point of the third hole is 90mm away from the edge of the second hole. The distance between the edges of one hole and the second hole is equal, and both are 90mm, and the centers of the three holes are connected to form an equilateral triangle;

[0030] 4) The disturbance generated during the drilling process naturally expands the extension of each hole, mak...

Abstract

The invention relates to a greening method for high and steep quartzite slopes in arid and rainless areas, which belongs to the field of regreening high and steep slopes. The method increases the aperture to 300mm in areas with less rainfall, but due to the high hardness of quartzite, the property is Brittle, serious wear and tear on the drilling rig, and the direct application of a 300mm-diameter drilling rig is costly and more difficult to construct. The method of the present invention uses a small-caliber drilling rig to drill three times in a triangle shape to complete the 300mm-diameter drilling. The cost is low, the time is short, and the construction difficulty is greatly reduced. , and more conducive to plant growth.

Description

technical field [0001] The invention belongs to the field of regreening of high and steep slopes, and in particular relates to a greening method for high and steep quartzite slopes in dry and rainless areas. Background technique [0002] The lithological characteristics of high and steep quartzite are: grayish white, grayish yellow, flesh red, partly purple red, medium-thick to thick layered, dense and hard, interbedded with thin layered blue-gray and purple-red slate, and part of the slate contains powder It is sandstone with sericitization on the joint surface and developed structural breccia. High and steep rocky slopes have always been a difficult point in disaster management and greening. There are small cracks and joints in the quartzite in the treatment area. High and steep rocky slopes have always been difficult in disaster management and greening. The greening method of drilling and backfilling planting soil on limestone slopes has achieved good results. Due to its...
