What are the requirements for the spacing between barns?

Considering that the distance between livestock and poultry houses should be determined according to the requirements of epidemic prevention, sewage discharge, fire prevention and lighting, and referring to other requirements, if the height from the outdoor terrace to the cornice of livestock and poultry houses is H(m), the four required distances s are as follows.

1). Livestock and poultry houses are the conditions for epidemic prevention and isolation, and the possibility of mutual infection between different livestock and poultry houses should be eliminated or reduced as much as possible. The distance between the open barn and the closed barn is 5H, that is, S epidemic = 3-5h.

2) Pollution discharge requirements. In order to improve the environment of livestock and poultry farms, we should consider the impact of pollution emissions from farms. Field sewage discharge needs woven natural ventilation, and the distance between livestock and poultry houses can be appropriately reduced by using the angle formed by the dominant wind direction and the long axis of livestock and poultry houses. Usually, the interval required for sewage discharge is S row =2H.

3) Fire protection requirements. In addition to setting fire hydrants according to regulations and improving the fire resistance of building materials for livestock and poultry houses, the fire distance of buildings is also a major fire prevention measure. Livestock and poultry houses are mostly brick-concrete structures, and the spacing meeting the fire protection requirements is S fire = 2-3h.

4) Lighting requirements. The spacing required for daylighting mainly considers the sunlight shading of open adjacent livestock houses, and the spacing requirement is S light = 1.5-2h.
