The material of the heat-insulating layer can be various, and typical materials include rigid polyurethane foam plastics, polystyrene foam plastics, hydrophobic expanded perlite, H-shaped foam plastic glass and the like. The roof receives the rainwater, the influence of snow, can the seepage income water, the heat preservation is the biggest layer body of trapped water volume, prior art is that the measure of depositing water for getting rid of the heat preservation is directly to insert at the heat preservation and establishes like the blast pipe 5 shown in fig. 5, wear each layer on the blast pipe, the export is located roof the superiors top, the intraformational water of heat preservation passes through the blast pipe with the gaseous state mode and discharges, it is slow to do drainage speed like this, low efficiency, the effect is poor, often can lead to the aspect inflation because of the heat preservation water content is too big, destroy the roof waterproof layer, something still can cause the roof to.

SUMMERY OF THE UTILITY MODEL

The utility model discloses it is slow to solve prior art roof heat preservation drainage speed, and the poor problem of effect provides for this reason the utility model discloses an abnormal shape drainage and exhaust pipe, this kind of drainage and exhaust pipe combine with the exhaust pipe of above-mentioned prior art, install in the roof, and drainage speed is fast, and is effectual.

In order to solve the problem, the utility model discloses a technical scheme, its special character is heterotypic drainage blast pipe has the arched body of cross section, and this arched body both sides respectively link there is the pterygoid lamina below the through-hole of arranging according to arched body length direction is seted up to the both sides wall of arched body.

The utility model discloses an abnormal shape drainage blast pipe and prior art among the blast pipe combination is installed in the roof, abnormal shape drainage blast pipe buries in the roof heat preservation, and abnormal shape drainage blast pipe connecting portion has the coupling, can have bi-pass, tee bend, four-way connection like ordinary coupling, the difference lie in this kind of coupling the joint cavity with abnormal shape drainage blast pipe configuration is corresponding. The pipe joint has an air outlet on the upper side, and the exhaust pipe is connected to the air outlet.

Work as the utility model discloses with the blast pipe combines to install in the roof, can also enclose on the heterotypic drainage blast pipe and has wrapped the geotechnological cloth.

Influenced by sleet, the roof is intake and is mostly amassed in the heat preservation, and heat preservation intraformational water has the liquid gaseous state also, the utility model discloses with supporting coupling with the blast pipe combines to install in the roof, the utility model discloses install in the roof heat preservation, liquid water and gaseous state water homoenergetic in the heat preservation can pass through

The through holes on two sides of the arched pipe body enter the special-shaped drainage exhaust pipe, the tail end of the special-shaped drainage exhaust pipe is provided with a water outlet, liquid water is discharged from the water outlet, and gaseous water is discharged through the air outlet of the pipe joint and the exhaust pipe connected with the air outlet.

The invention is further described with reference to the following figures and detailed description.
