Problems solved by technology

The general treatment methods for such slopes are to cut slopes and open slopes, build retaining walls, and restore vegetation with foreign soil. However, there is no treatment for the soft soil foundation formed at the foot of the slope due to heavy rain, and a large amount of foreign soil is required. ,high cost

Embodiment 1

[0025] A method for repairing the side slope of a gravel pile in a quarry, comprising the following steps:

[0026] (1) Carry out manual / mechanical cleaning of dangerous rocks on the side slope of the rubble pile;

[0027] (2) Calculate the amount of slope cut and calculate the slope coefficient, and calculate the distance between the new slope foot and the original slope foot after slope grading;

[0028] (3) Excavating a 2-3 deep ditch on the soft ground at the foot of the slope, and preparing the planting soil with the excavated soil. The method for preparing the planting soil includes the following steps:

[0029] A. Mix 50% of soil, 10% of cow dung, 20% of sludge and 20% of biogas residue to obtain a mixture;

[0030] B. Add biogas slurry to the mixture in step A, and the amount of biogas slurry to be added per cubic meter of planting soil is 0.2L and stir evenly to obtain stack retting material;

[0031] C. Stack the retting material in step B into a 1m-high stockpile,...

Embodiment 2

[0036] A method for repairing the side slope of a gravel pile in a quarry, comprising the following steps:

[0037] (1) Carry out manual / mechanical cleaning of dangerous rocks on the side slope of the rubble pile;

[0038] (2) Calculate the amount of slope cut and calculate the slope coefficient, and calculate the distance between the new slope foot and the original slope foot after slope grading;

[0039] (3) Excavating a 2-3 deep ditch on the soft ground at the foot of the slope, and preparing the planting soil with the excavated soil. The method for preparing the planting soil includes the following steps:

[0040] A. Mix 45% of soil, 12% of cow dung, 25% of sludge, and 18% of biogas residue to obtain a mixture;

[0041] B. Add biogas slurry to the mixture in step A, and the amount of biogas slurry to be added per cubic meter of planting soil is 0.2L and stir evenly to obtain stack retting material;

[0042] C. Stack the retting material in step B into a 1m-high stockpile...

Abstract

The invention provides a quarry rubbish dump side slope repair method which includes the steps: (1) cleaning dangerous rocks; (2) calculating slope cutting quantity and measuring slope setting coefficient; (3) excavating a ditch under a side slope toe and preparing planting soil by the aid of excavated soil; (4) accumulating massive rocks and the dangerous rocks in the ditch and then performing slope cutting and slope setting; (5) covering a side slope with the planting soil and then restoring vegetations according to selected plants. The repaired side slope toe is high in stability, landslideis not easily caused, the dangerous rocks and the massive rocks can be stored, treatment cost is reduced, secondary pollution is avoided, the soil excavated at the toe is used for preparing the planting soil, replaced soil usage amount is decreased, secondary harm of a replaced soil source is reduced, the prepared planting soil is high in nutrient, plant growth effects are good, late topdressingis decreased, and cost is reduced. In addition, a large quantity of sludge solid wastes can be consumed, environmental pollution is reduced, resource use rate is high, and the method has good economicand social benefits.

Description

technical field [0001] The invention relates to the technical field of slope repair and environmental protection, in particular to a method for repairing a side slope of a gravel pile in a quarry. Background technique [0002] Landslide geological disasters occur every year in our country, especially in summer. When a landslide occurs, a certain amount of rock and soil moves from a high place to a low place, causing losses or casualties to buildings or people along the way. In order to effectively avoid the occurrence of landslide disasters, it is necessary to carry out reinforcement design for unstable slopes during slope design, so as to ensure that the slope remains stable during the operation phase. [0003] The gravel pile in the quarry is a huge artificial loose accumulation formed by accumulating the stripped topsoil and unshaped stone when the profile quarry is mining and cutting the shaped stone, which is very easy to cause geological disasters such as landslides a...
