Abstract

An elastic pipe (5) is fixed by a clamp ring (7) in the bottom of the damaged street gutter well, and extends to the well street level where it is fastened.

Description

459 591 grävas upp. Man bör dock helst rensa brunnen på den sand och jord, som sam- lats på bottnen av bottendelen 2. 459 591 are excavated. However, it is best to clean the well of the sand and soil that has accumulated on the bottom of the bottom part 2.

Anordningen består av ett uppåt riktat, elastiskt rör 5 resp. 6, vars nedre del med hjälp av en spännring 7 anbringats i bottendelen 2 ovanför utloppet 3 i denna. Nertill är röret 5 resp. 6 förstorat samt försett med ett runt in- ß sidan av den förstorade delen gående spår 16 för spännringen 7, vilken ut- ä göres av en i ena änden sluten slang 7. Då slangen utsättes för en tryckök- ning vill den räta ut sig, vilket innebär att den då.kommer att vidga röret 5 resp. 6 nertill och spänna fast detta vid bottendelen 2.The device consists of an upwardly directed, elastic tube 5 resp. 6, the lower part of which is fitted by means of a clamping ring 7 in the bottom part 2 above the outlet 3 therein. At the bottom, the tube is 5 resp. 6 enlarged and provided with a groove 16 for the clamping ring 7 running around the inside of the enlarged part, which is formed by a hose 7 closed at one end. When the hose is subjected to an increase in pressure, it wants to straighten out, which means that it will then widen the tube 5 resp. 6 at the bottom and fasten this to the bottom part 2.

Det elastiska röret består enligt utförandena i fig l och fig 2 av en rör- formad ring 5 av elastiskt material, 1 vilken är förskjutbart anbringat ett rör 8 av plast e.d., exempelvis ett PVC-rör, som är anordnat att sträcka sig till gatans nivå, där det är fäst vid den ring 9 som uppbär brunnslocket 10.According to the embodiments in Fig. 1 and Fig. 2, the elastic tube consists of a tubular ring 5 of elastic material, 1 which is slidably mounted on a tube 8 of plastic ed, for example a PVC tube, which is arranged to extend to the street level. , where it is attached to the ring 9 supporting the manhole cover 10.

Vid utförandet enligt fig 5 utgöres det elastiska röret av en elastisk strum- pa 6, som är försedd med ett antal armeringsringar ll, som spänner ut och förstärker strumpan. Denna sträcker sig upp till gatans nivå, där den är fäst vid ringen 9, som uppbär brunnslocket lO.In the embodiment according to Fig. 5, the elastic tube consists of an elastic sock 6, which is provided with a number of reinforcing rings 11, which stretch and reinforce the sock. This extends up to the level of the street, where it is attached to the ring 9, which carries the manhole cover 10.

Genom elasticiteten hos röret S resp. 6 blir rännstensbrunnen intakt även om betongringarna l skulle utsättas för ytterligare tjälskador. f vid de visade utförandena består spännringen Y av en vid den ena änden slu- ten slang 7, som är anbringad i spåret 16 i det elastiska rörets 5 resp. 6 nedre, förstorade del och som är fylld med ett antal efter varandra anbringade kulor 12, vilka är anordnade att kunna pressas mot varandra från slangens 7 öppna ände. Vid denna ände är slangen förenad med ett uppåt riktat stålrör 13, som innehåller ett antal efter varandra anordnade kulor l4, som står i för- bindelse med kulorna 12 i slangen 7. Vid sin från slangen vända ände är stål- röret 15 försett med en gängning, som samverkar med en skruv 15, vilken an- ligger mot den yttersta kulan i raden av kulorna.l4. Skruven 15 är anordnad att kunna vridas med hjälp av verktyg från brunnens gatunivå. Då skruven skruvas i kommer kulorna 14 i stålröret 13 och kulorna 12 i slangen 7 att pressas moï'varandra, så att slangen 7 vill rätas ut, varigenom det elastiska röret 5 resp. 6 kommer att spännas fast mot bottendelens 2 insida.Due to the elasticity of the tube S resp. 6, the gutter well becomes intact even if the concrete rings 1 were to be exposed to further frost damage. f in the embodiments shown, the clamping ring Y consists of a hose 7 closed at one end, which is arranged in the groove 16 in the elastic tube 5 resp. 6, enlarged part and which is filled with a number of balls 12 arranged one after the other, which are arranged to be able to be pressed against each other from the open end of the hose 7. At this end, the hose is connected to an upwardly directed steel pipe 13, which contains a number of balls 14 arranged one after the other, which are connected to the balls 12 in the hose 7. At its end facing away from the hose, the steel pipe 15 is provided with a threading, which cooperates with a screw 15, which abuts against the outermost ball in the row of balls.14. The screw 15 is arranged to be able to be turned by means of tools from the street level of the well. When the screw is screwed in, the balls 14 in the steel tube 13 and the balls 12 in the hose 7 will be pressed against each other, so that the hose 7 wants to be straightened, whereby the elastic tube 5 resp. 6 will be clamped against the inside of the bottom part 2.

För att helt eliminera risken för köldskador på en rânnstensbrunn bör anord- ningen enligt uppfinningen anbringas i brunnen redan då den byggs.In order to completely eliminate the risk of cold damage to a curbstone well, the device according to the invention should be fitted in the well already when it is being built.
