Problems solved by technology

[0003] In road construction, after the earthwork is transported out, it is necessary to backfill the crushed concrete blocks, and the backfilling of the crushed stone concrete blocks will generate a large amount of dust, so it needs to be treated. There is no specific problem of dust generated by the backfilling of crushed stone concrete blocks in the prior art. processing, thus requiring further R&D processing

Embodiment 1

[0025] A method for backfilling gravel concrete blocks to reduce dust in this embodiment comprises the following steps:

[0026] Step 1. Arrangement of collecting sieves: arrange collecting sieves around the road backfill, the particle size of the collecting sieves reaches 1mm, and then arrange blowers and dust blowers on both sides of the backfill road;

[0027] Step 2: Blower and dust blower work together to remove dust: the blower and dust blower are used to jointly cooperate with blower and dust blower to generate dust generated by the backfilling of crushed stone concrete blocks. The blower is started, and the blower absorbs part of the dust into the dust removal box, and the dust blower is started. The mist water produced by the dust blower Settling dust;

[0028] Step 3, finishing treatment: the dust generated by the dust blower falls into the collection screen arranged in step 1, the dust generated by the blower blows into the dust removal box, and the road backfilling...

Embodiment 2

[0037] A method for backfilling gravel concrete blocks to reduce dust in this embodiment comprises the following steps:

[0038] Step 1. Arrangement of collecting sieves: arrange collecting sieves around the road backfill, the particle size of the collecting sieves reaches 2mm, and then arrange blowers and dust blowers on both sides of the backfill road;

[0039] Step 2: Blower and dust blower work together to remove dust: the blower and dust blower are used to jointly cooperate with blower and dust blower to generate dust generated by the backfilling of crushed stone concrete blocks. The blower is started, and the blower absorbs part of the dust into the dust removal box, and the dust blower is started. The mist water produced by the dust blower Settling dust;

[0040] Step 3, finishing treatment: the dust generated by the dust blower falls into the collection screen arranged in step 1, the dust generated by the blower blows into the dust removal box, and the road backfilling...

Embodiment 3

[0049] A method for backfilling gravel concrete blocks to reduce dust in this embodiment comprises the following steps:

[0050] Step 1. Arrangement of collecting sieves: arrange collecting sieves around the road backfill, the particle size of the collecting sieves reaches 1.5mm, and then arrange blowers and dust blowers on both sides of the backfill road;

[0051] Step 2: Blower and dust blower work together to remove dust: the blower and dust blower are used to jointly cooperate with blower and dust blower to generate dust generated by the backfilling of crushed stone concrete blocks. The blower is started, and the blower absorbs part of the dust into the dust removal box, and the dust blower is started. The mist water produced by the dust blower Settling dust;

[0052] Step 3, finishing treatment: the dust generated by the dust blower falls into the collection screen arranged in step 1, the dust generated by the blower blows into the dust removal box, and the road backfilli...

Abstract

The invention discloses a method for reducing raised dust by backfilling gravel concrete blocks, and the method comprises the following steps of: 1, arranging a collecting screen, specifically, arranging the collecting screen around a backfilled road, enabling the particle size of the collecting screen to reach 1-2mm, and arranging an air blower and a dust raising machine on two sides of the backfilled road; and 2, performing dust removal through the air blower and the dust raising machine jointly, specifically, the air blower and the dust remover cooperate jointly to performing dust removal on the raised dust generated by backfilling of the gravel concrete blocks, the air blower is started, the air blower sucks part of the dust into a dust removal box, the dust raising machine is started,and mist water generated by the dust raising machine is used for settling the dust. The dust can be effectively settled, and meanwhile, a series of environment-friendly treatment concepts are adoptedin dust treatment, so that the dust treatment effect is improved to a great extent.

Description

technical field [0001] The invention relates to the technical field of backfilling crushed stone concrete blocks, in particular to a method for reducing dust by backfilling crushed stone concrete blocks. Background technique [0002] Flying dust is an open pollution source that enters the atmosphere due to the dust on the ground being driven by wind, man-made or other driving forces. It is the most effective way to avoid the repeated formation of dust after the road soil is air-dried. At the same time, it can avoid the formation of dust by cleaning in sunny days, and it can also greatly save cleaning water. It is a measure that the majority of cities and towns in China should take immediately; when designing and constructing hardened roads, pay attention Strictly adopting reasonable road surface slope and road edge drainage design, and using natural precipitation runoff to wash and clean road dust can achieve twice the result with half the effort in reducing dust pollution, ...
