A construction site is a dirty, dusty place during much of its evolution from bare ground to finished product. Street sweeping equipment, like that from USA Services of Florida, is excellent for keeping construction debris and dirt from becoming a problem. However, since a construction site offers unique challenges for street sweeping equipment, there are a few things you should keep in mind so their use can be maximized. Below are three particular considerations that can help your sweet sweeper perform to its highest level and give you the most use at your site:
Use the right brushes
Street sweeper brushes are available in a variety of styles and quality levels. It is important to remember that brushes are purposely made to handle different types of debris. For example, a brush that is designed to pick up ordinary urban road litter, such as fine particles of dirt, paper and plastic trash, leaves and grass clippings, will not suffice on a construction site.
Consider using brushes with heavy, coarse wire strands; these brushes can withstand sweeping tough particles such as concrete particles, sand and other abrasive materials. Choose brushes that won't clog easily and that need minimal amounts of maintenance. In addition, remember that street sweeper brushes are like any other purchase; you will get what you pay for, as cheap brushes won't last, and the hassle of changing them frequently will cost you both time and money.
Consider a litter hose
Not all street sweepers are equipped with litter hoses or litter hose fittings, but they are a great option to have on a job site. Litter hoses are essentially giant vacuum hoses attached to the street sweeper's main vacuum system. Ordinarily, all of the suction is diverted to the street sweeper's ground-level vacuum intake; for normal street and parking lot debris, that is where the system works best.
However, on a construction site, a litter hose system allows operators to pinpoint their debris and construction waste collection efforts. Some specific applications where you find a litter hose particularly useful include:
Corners and crevices of framing or pouring locations
Small concrete chips and pieces
Wet holes that need water evacuation
If you decide to use a litter hose, you will need to have a properly-equipped system that is capable of handling the particularly heavy-duty nature of construction waste. Hoses, vacuum tanks, and intake attachments all should be rugged enough so they don't fail during the course of duty.
Keep airborne particulate levels low
Another consideration to keep in mind is that construction sites often generate a tremendous amount of airborne particulates. The action of digging and exposing bare soil as well as the import of sand and other aggregates to the site generate a lot of loose material. During dry or windy periods, this can become a significant problem for both people and the environment.
Street sweeping is an important means of controlling the amount of loose debris. However, even sweepers that use water in their collection systems may not be able to cope with the sheer amount of material and might actually make a dust problem worse. That's where augmenting collection efforts with additional spray-down can help.
Additional water spraying can be performed with the use of handheld hoses on smaller sites. However, for larger areas, it becomes impractical to use crews for water spray-down. The installation of irrigation equipment, such as hoses and portable sprinklers, can help reduce the amount of manpower needed. In addition, permanent irrigation equipment can be installed early in the construction process and under-lawn sprinklers can be used to help aid in dust control efforts. Once loose materials are dampened, the sweeper can collect them more easily and without blowing up dust.
