Windbreak and Dust Suppression System Design Content

1. General layout design

The windbreak and dust suppression net can be installed all around the storage yard, or just in the strongest upwind direction. Green Technology has also three-side system available. The system will be designed according to size and shape of the yard, local wind direction, wind frequency and other weather conditions.

The best distance between the windbreak and dust suppression wall and the stock pile has to be equal to two or three times its height (stock pile). For the storage yard composed of multiple piles, the windbreak wall can be placed based on local conditions. Generally speaking, it can be installed along the edge of the stock pile.

During actual construction, we should not only consider natural conditions, but also keep in mind the field conditions. The on-site investigation mainly includes the survey of constructions, mechanical equipment, underground pipelines, roads and other facilities in the yard. Only by doing the deep investigation on the field conditions can we ensure that the construction of our windbreak and dust suppression net will not affect the normal operation of the storage yard and function of its auxiliary facilities.

2. Height design

The height of the windbreak and dust suppression net mainly depends on stacking height, generally 1.1 to 1.5 times the height of the stock pile. When determining the height, we should also take into account the yard size to make sure that the stack materials can be well protected within the scope of effective shelter.

3. Steel structure design

The steel structure design mainly includes the overall structure design, steel bar sizing and selection, connection scheme, support bar and frame design, as well as the steel temperature joint design.

When designing the steel structure of the windbreak and dust suppression net, we should calculate equivalent static wind pressure and make a static analysis of the stress and displacement. For the large-scale yard, coming with a length of more than one kilometer and a height of more than ten meters, we have to further study the dynamic load, resistance coefficient, vibration and other security issues.

4. Foundation design

When doing the foundation design of windbreak and dust suppression net, we should determine the structure type and cross-section dimensions. In addition, it also includes the design of reinforcement bar and deformation joint.
