role funnel rainwater drainage system

Installation of drainage funnels determined the general plan of their placing on the roof and facade of the building.So, if disorganized drainage system when the rainfall from the roof drains directly to the ground, the installation of speech can not go.And such a system is often used for small buildings (often with a pent roof).

For systems organized internal drainage characterized by the location of the drain risers, and they are used in high-rise building structurally with flat roofs.As a rule, a funnel internal drainage is formed in the center of the profile grooves to drain.

obligatory element of this design is the presence of a special funnel strainer prevents the ingress into the standpipe drain pipe leaves, debris, contributing to its clogging.The principle of operation is very similar to the drain system in the shower tray.Like the shower drain, internal drains need regular maintenance and control of the funnel filter, since their blockage is quite possible undesired accumulation of rain on the roof.

In addition, for the winter period, when the possibility of periodic freezing and thawing of the liquid on the roof, guarantee the safe operation of the entire storm water drainage system will funnel with electrically heated (its design also includes filters).

Plastic drains

system include advanced materials manufacturing elements are gaining popularity plastic drain.With the necessary strength and resistance to external influences, the plastic elements are lightweight.For example, funnel rainwater cast iron is very often the cause of the destruction of the waterproofing layer at the point of attachment at the same time firmly closing plastic funnel the joints with roofing materials and sealing compositions, without damaging them.

Speaking of manufacturing materials.For systems used by organized outdoor Photo taken to apply the elements of one hundred millimeters in diameter.It is customary to all riser pipe drain rainwater and funnel diameter 100 mm made of galvanized iron.However, such systems have produced reconstruction of the funnel, which allow for changing defective metal elements are more durable plastic.

Principles funnels placed on effluent

As is known, when the outer gutter all communications to melt runoff and rainfall are located outside of house designs.For their attachment using special mounting brackets, holders, etc. Depending on the diameter of the chute for receiving payment of precipitation from the roof gutter amount being funnels (average) of not less than one for each ten meters of the receiver.

Iewhen the facade length of about twenty meters should be at least two funnels (and preferably three: two on the edges and in the middle of a flow).Depending on the organization collecting water places (external drain) flowing down from the roof, installation of gutters funnels can be mounted them to the construction of drainage gutters to be inserted into the upper edge of the pipe drain standpipe or by simply inserting the upper end of the pipe, in the absence of gutters and availabilityguides on the roof drain.

way, and outdoor sinks are special filters - "spiders" to prevent clogging of the risers.Mounting for internal gutters involves special flange mounting and additional waterproofing measures funnels.

And what about the number of funnels with an internal gutter?And then the number of drainage funnels standardized minimum acceptable value.Thus, for the area to be seven hundred squares at least one funnel, but not less than one hundred millimeters.If the area of ​​roofs and walls have a deformation seams, then each such area (regardless of size) should be at least two funnels.
