Abstract

The invention concerns a road culvert in which there are two or more culvert pipes 1, 2. In the road culvert according to the invention, the inlet opening 3 of at least one culvert pipe 2 is situated higher up than the main inlet opening 4 formed by the other culvert pipe 1 of the road culvert. By means of the invention it is possible to avoid freezing of the road culvert, which is the most serious disadvantage of the known road culverts. <IMAGE>

Description

468 055 10 15 20 25 30 3.5 2 tvenne trumrör, av vilka det till sin diameter mindre trumröret 2 befinner sig innanför det till sin diameter större trumröret 1. Det mindre trumrörets insugningsöppning 3 befinner sig högre upp än det större trumrörets insugningsöppning 4, dock nedanför vägytan 5. Det mindre trumrörets utströmningsöppning 6 är emellertid i. denna tillämpning belägen högre upp än det större trumrörets utströmnings öppning 7. Utströmingsöppningens läge kan variera i olika tillämp- ningar. Med en streckad linje 8 har framställts utströmningsöpp- ningens placering på den konventionella nivån. Det mindre trumrörets ända 9 är i denna tillämpning näbbliknande för före- byggande av att regnvatten och föroreningar tränger in i trumröret. 468 055 10 15 20 25 30 3.5 2 two drum tubes, of which the smaller tube tube 2 smaller in diameter is located inside the drum tube 1 larger in diameter 1. The smaller drum tube suction opening 3 is located higher up than the larger drum tube suction opening 4, however below the road surface 5. However, the outflow opening 6 of the smaller drum tube is in this application located higher up than the outflow opening 7 of the larger drum tube. The position of the outflow opening can vary in different applications. A dashed line 8 shows the location of the outflow opening at the conventional level. The end 9 of the smaller drum tube is in this application beak-like to prevent rainwater and contaminants from penetrating the drum tube.

I olika tillämpningar kan ett skydd erhållas även på andra kända sätt, t ex med hattlock och liknande anordningar.In various applications, a protection can also be obtained in other known ways, for example with hat caps and similar devices.

Om och när i vägtrumman bildas is 10, tillsluter isen endast det till sin diameter större trumröret. Det till sin diameter mindre trumröret förblir öppet, varvid översvämningsvattnet i diket kan strömma ut i utloppskanalen genom det mindre trumröret, innan det hinner stiga upp på vägen.If and when ice 10 is formed in the road drum, the ice only closes the drum tube larger in diameter. The smaller diameter of the drum tube remains open, whereby the flood water in the ditch can flow out into the outlet channel through the smaller drum tube, before it has time to rise on the road.

I det till sin diameter mindre trumröret får inte bli kvar vatten på hösten. Avíägsnande av vattnet kan vara viktigt också på våren, då blidväder och frostväder varierar. Avlägsningsproblem av vatten förekommer inte i sådana fall, när utströmningsöppningen på det till sin diameter mindre trumröret befinner sig på samma nivå eller längre ner än själva röret. Hos en dylik lösning kan man se till, att utströmningsöppningen hålles isfri genom att det till sin diameter mindre trumröret placeras i vägtrummans övre del. I ett U- formigt trumrör bör tömningen utföras antingen med en manuellt opererad eller en automatiskt fungerande avtappningsventil eller motsvarande anordning. Ventillösningen är inte framställd på ritningen.In the smaller tube diameter, the water must not remain in the autumn. Removal of the water can also be important in the spring, when mild weather and frosty weather vary. Problems with water removal do not occur in such cases, when the outflow opening on the smaller diameter of the drum tube is at the same level or further down than the tube itself. With such a solution, it can be ensured that the outflow opening is kept ice-free by placing the smaller pipe tube in the upper part of the road drum in its smaller diameter. In a U-shaped drum tube, emptying should be performed with either a manually operated or an automatically operating drain valve or similar device. The valve solution is not shown in the drawing.

Tillfrysningsproblemet på våren av det till sin diameter mindre trumröret i vägtrumman i enlighet med den på ritningen framställda lösningen kan undvikas genom att man värmeisolerar röret. Isola- tionens tjocklek är beroende av var det mindre trumröret befinner 468 G55 10 15 20 25 30 35 3 sig. Hos somliga lösningar behövs ingen värmeisolering.The freezing problem in the spring of the drum tube smaller in diameter in the road drum in accordance with the solution prepared in the drawing can be avoided by thermally insulating the tube. The thickness of the insulation depends on where the smaller drum tube is located 468 G55 10 15 20 25 30 35 3. Some solutions do not require thermal insulation.

I andra tillämpningar av uppfinningen kan vägtrumman bildas av fler än två trumrör och i somliga tillämpningar befinner sig trumrören inte innanför varandra utan bredvid varandra och i somliga tillämp~ ningar t o m på ett litet avstånd från varandra.In other applications of the invention the road drum may be formed by more than two drum tubes and in some applications the drum tubes are not inside each other but next to each other and in some applications even at a small distance from each other.

En vanlig vägtrumma omvandlas till en vägtrumma i enlighet med upp- finningen genom att man placerar innanför eller möjligen utanför den ett tilläggstrumrör, t ex på det sätt, som är framställt på ritningen. Uppfinningen omfattar naturligtvis också en dylik lösning.An ordinary road drum is converted into a road drum in accordance with the invention by placing an additional drum tube inside or possibly outside it, for example in the manner shown in the drawing. Of course, the invention also encompasses such a solution.

Uppfinningen är inte begränsad till de framställda fördelaktiga tillämpningarna, utan den kan variera inom ramen av patentkraven.The invention is not limited to the advantageous applications produced, but it may vary within the scope of the claims.
