Foundation trench earthwork construction dustproof shed and erecting method

Abstract

The invention provides a foundation trench earthwork construction dustproof shed and an erecting method. The foundation trench earthwork construction dustproof shed comprises a dustproof shed body. The dustproof shed body comprises supporting stand columns, horizontal guide rails, ceiling net body pull rods, ceiling net bodies, side face net body pull rods and side face dust screen bodies. The tworows of supporting stand columns form the two opposite side faces of the dustproof shed body. The two horizontal guide rails are fixed to the two rows of the supporting stand columns. The two horizontal guide rails are provided with opposite C-shaped sliding grooves. A plurality of electric rollers are arranged in each C-shaped sliding groove. The two ends of the ceiling net body pull rods are connected with rotary shafts of the electric rollers in the two C-shaped sliding grooves. One ends of the multiple ceiling net bodies are connected with one ceiling net body pull rod, and the other endsof the multiple ceiling net bodies are connected with the other ceiling net body pull rod. The side face net body pull rods are arranged below the horizontal guide rails. The upper portions of the side face dust screen bodies are fixed to the side face net body pull rods and droop downwards. The foundation trench earthwork construction dustproof shed is convenient to install and dismantle, the span and height of the dustproof shed can be increased or decreased according to the size of a foundation trench, and raising dust can be effectively suppressed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a dust-proof shed for foundation trench earthwork and a construction method thereof. Background technique [0002] At present, whether it is housing construction, underground comprehensive pipe gallery, municipal road and underground pipe network pipeline construction, earthwork operations are required. During earthwork operations, a large amount of particles and dust will be generated, causing environmental pollution and endangering surrounding residents, especially in northern weather. Dry, during the excavation, backfilling or mixing of earthwork will cause sand and gravel material dust to float in the air, which will seriously affect the air quality. The sprinkler system continues to reduce dust, but often due to the large operation area of ​​the foundation trench, the spray range is difficult to cover the middle of the foundation trench, resulting in poor dust ...

Problems solved by technology

[0002] At present, whether it is housing construction, underground comprehensive pipe gallery, municipal road and underground pipe network pipeline construction, earthwork operations are required. During earthwork operations, a large amount of particles and dust will be generated, causing environmental pollution and endangering surrounding residents, especially in northern weather. Dry, during the excavation, backfilling or mixing of earthwork will cause sand and gravel material dust to float in the air, which will seriously affect the air quality. The sprinkler system continues to reduce dust, but often due to the large operation area of ​​the foundation groove, the spray range is difficult to cover the middle of the foundation groove, resulting in poor dust control effect, and PM2.5 on the construction site cannot be effectively reduced
