Embodiment 1

[0016] A method for preventing the over-humidity of the foreign soil from clogging the pipeline in the dry spraying operation of the foreign soil on the side slope, comprising the following steps:

[0017] 1) Prepare improved foreign soil: add crushed stone and rice bran to the water-containing foreign soil, stir and mix evenly, and the mass ratio of the water-containing foreign soil, crushed stone and rice bran is 84%:8%:8%; The moisture content of guest soil is 36.5%;

[0018] 2) Spray the improved foreign soil on the side slope of the mountain beside the road through the dry spraying process of foreign soil.

Embodiment 2

[0020] A method for preventing the over-humidity of the foreign soil from clogging the pipeline in the dry spraying operation of the foreign soil on the side slope, comprising the following steps:

[0021] 1) Prepare improved foreign soil: add machine-made sand and sawdust to the water-containing foreign soil, stir and mix evenly, and the mass ratio of the water-containing foreign soil, machine-made sand and sawdust is 70%:15%:15%; the water-containing foreign soil The water quality is 60%;

[0022] 2) Spray the improved foreign soil on the side slope of the mountain beside the road through the dry spraying process of foreign soil.

Embodiment 3

[0024] A method for preventing the over-humidity of the foreign soil from clogging the pipeline in the dry spraying operation of the foreign soil on the side slope, comprising the following steps:

[0025] 1) Prepare improved soil: add ceramsite and rice straw powder to the water-containing soil, stir and mix evenly, the mass ratio of the water-containing soil, ceramsite and rice straw powder is 91%:4%:5%; The water content of the above-mentioned water-bearing foreign soil is 30%;

[0026] 2) Spray the improved foreign soil on the side slope of the mountain beside the road through the dry spraying process of foreign soil.

Abstract

The invention discloses a method for preventing a pipeline from being blocked by too-wet dressing soil in slope dressing soil dry-spraying operation. The method includes the following steps that firstly, improved dressing soil is prepared, wherein a sand material and vegetable matter are added to the water-contained dressing soil to be stirred and evenly mixed; and secondly, the improved dressing soil is sprayed to a mountain slope beside a road through a dressing soil dry-spraying process. By the adoption of the method, a dressing soil ratio improving method is adopted, bonded particles are effectively scattered, the matrix wall bonding phenomenon is effectively avoided, viscosity is reduced, and the aggregation phenomenon is reduced; the wall bonding phenomenon is reduced; and the pipeline blocking phenomenon generated in dry-spraying operation can be effectively prevented, smooth construction is guaranteed, waste is used, cost is reduced, the soil is evenly sprayed to the slope face of the slope, the construction progress is guaranteed, and the afforesting effect of the slope can be guaranteed.

Description

technical field [0001] The method relates to a method for preventing an over-wet substrate from clogging a pipeline in dry spraying operations for slopes, and belongs to the technical field of road slope ecological protection. technical background [0002] Road construction plays a decisive role in economic development, but because human-made construction often has a certain negative impact on the natural environment, especially in mountainous and hilly areas, road construction often requires operations such as cutting slopes on the mountain, which affects the terrain. More excavation. These excavated slopes not only affect and destroy the overall landscape of the road, but most of them are not in a stable state, and often have destructive behaviors such as collapse, gravel collapse, landslide, and mud-rock flow. Therefore, the treatment and greening measures for slopes are important means to control these slopes. The governance model with cement as the main material used ...
