Description

i7714soo-9 g 2 nackdel och detta uppnås genom en brunn av den utformning, som är närmare definierad i bifogade patentkrav. i7714soo-9 g 2 disadvantage and this is achieved through a well of the design, which is further defined in the appended claims.

En utfóringsfom av uppfinningen komer i det följande att 'beslmivas i detalj under hänvisning till bifogade ritningsfigurer, av vilka fig. 1 i axiell sektion visar en brunn enligt uppfinning- en, anbringad i marken, och fig. 2 är en planvy uppifrån av brunnen g enligt fig. 1.An embodiment of the invention will hereinafter be described in detail with reference to the accompanying drawing figures, of which Fig. 1 shows in axial section a well according to the invention, mounted in the ground, and Fig. 2 is a plan view from above of the well g according to Fig. 1.

Enligt fig. 1 innefattar brunnen ett cylindriskt rör 1, lämp- ligen av betong eller plastmaterial, som är nedgrävt med axeln i vertikalt läge i marken och vars övre kant 2 är belägen ett stycke nedanför markytan 5.According to Fig. 1, the well comprises a cylindrical pipe 1, suitably of concrete or plastic material, which is buried with the shaft in a vertical position in the ground and whose upper edge 2 is located some distance below the ground surface 5.

Ett första ramelement 4 är anbringat vid betongrörets 1 övre ände och uppvisar ett nedåtriktat, cylindriskt rörparti a 5, vilket är inskjutet i betongröret 1. Det första ramelementet 4 innefattar dessutom ett uppåtrilctat, cylindriskt rörparti 6. Det nedåtriktade rörpartiets 5 axel 7 är parallell med det uppåtriktade rörpartiets 6 axel 8, men är radiellt förskjuten i förhållande till denna. Det uppåtriktade rörpartiet 6 har lämpligen en invändig diameter, som motsvarar den utvändiga diametern hos det nedåtriktade partiet 5 av skäl, som anges i det följande. Genom den excentriska placering- en av de två rörpartiernas axlar 7 och 8, skjuter rörpartierna 5 och 6 utanför varandra vid diametralt motsatta sidor hos ram- elementet 4. De därigenom uppstående, skärformade ändpartierna hos de två rörpartierna är tillslutna medelst vardera en skär-formad, mot rörpartiernas axlar vinkelrät vägg 9' resp. 9". Väggen 9' , som tillsluter det utskjutande ändpartiet hos det nedåtriktade rör- partiet 5 är förlängd utåt med en fläns 10, som ligger i plan med väggen 9'. Den nedåtriktade ytan hos flänsen 10 ligger i sin tur i plan med den nedåtriktade ytan hos väggen 9", som tillsluter det uppåtriktade rörpartiets 6 utskjutande ändparti, och dessa två nedåtriktade ytor-bildar tillsammans en bäryta 11, som anligger mot betongrörets 1 övre kant 2.A first frame element 4 is arranged at the upper end of the concrete pipe 1 and has a downwardly directed cylindrical pipe portion a 5, which is inserted into the concrete pipe 1. The first frame element 4 further comprises an upwardly directed, cylindrical pipe portion 6. The axis 7 of the downwardly directed pipe portion 5 is parallel to the axis 8 of the upwardly directed pipe portion 6, but is radially displaced relative thereto. The upwardly directed pipe portion 6 suitably has an inner diameter which corresponds to the outer diameter of the downwardly directed portion 5 for reasons stated below. Due to the eccentric placement of the shafts 7 and 8 of the two pipe sections, the pipe sections 5 and 6 project outside each other at diametrically opposite sides of the frame element 4. The resulting cutting-shaped end sections of the two pipe sections are closed by means of a cutting-shaped one each. , against the axes of the pipe sections perpendicular wall 9 'resp. The wall 9 ', which closes the projecting end portion of the downwardly directed pipe portion 5, is extended outwards with a flange 10 which is flush with the wall 9'. The downwardly directed surface of the flange 10 is in turn flush with the the downwardly directed surface of the wall 9 ", which closes the projecting end portion of the upwardly directed pipe portion 6, and these two downwardly directed surfaces together form a bearing surface 11, which abuts against the upper edge 2 of the concrete pipe 1.

Ett andra ramelement 12 innefattar ett cylindriskt rörstycke 14 med samma ytterdiameter som det första ramelelnentets 4 nedåt- riktade rörparti 5, så att rörstycket med lämplig passning är in- skjutbart i det första ramelementets 4 uppåtriktade rörparti 6, _ men även om så önskas direkt i betongröret 1.A second frame element 12 comprises a cylindrical pipe piece 14 with the same outer diameter as the downwardly directed pipe portion 5 of the first frame element 4, so that the pipe piece with a suitable fit is slidable in the upwardly directed pipe portion 6 of the first frame element 4, but even if desired directly in the concrete pipe 1.

När brunnen är en rännstensbrunn övergår det nedtíll cirkulära innerutrymmet hos det andra ramelementet 12 upptill i en rektangu- lär öppning, avsedd att taga upp ett rännstensgaller 15. Vid över-When the well is a gutter well, the downward circular inner space of the second frame element 12 merges at the top into a rectangular opening, intended to receive a gutter grid 15. At the top

Claims

7114600-9 between the circular inner space and the rectangular opening, the frame element 12 is provided with a shoulder 17, which can extend completely around the opening or along two of its opposite sides and whose upper flat surface serves as a bearing surface for the gutter grate 15. the frame element 12, on the other hand, is intended for a descent well, its inner space is non-circular over its entire length and the inwardly directed shoulder 16 is annular or intended to support a lid. At the upper edge, the frame element 12 is also provided with a radially projecting flange 18. If the upper opening of the frame element 12 is rectangular, this flange 18 suitably extends along three of the sides of the opening, especially along a long side and two short sides. If the upper opening is circular, the flange 18 may suitably be eccentric relative to the pipe section 14, so that it is narrower on one side or where its outer periphery is tangent to the pipe section 14. The well according to the invention is applied in the following manner. First, the concrete pipe 1 is dug into place in the ground, after which the work on the overlying street or road is completed with the exception that a hole is left for the frame elements. The first frame element 4 is then pushed with its downwardly directed pipe portion 5 into the concrete pipe 1, until the support surface 11 rests against its upper edge 2. By turning the first frame element 4-in the concrete pipe 1, its upwardly directed pipe portion 6 can due to the radial displacement between the shafts 7 and 8 is moved in the horizontal plane, so that it can be aligned in a suitable position relative to an adjacent gutter edge, house wall or the like. When this alignment is completed, the second frame element 12 is inserted with its pipe section 14 into the upwardly directed pipe portion 6 of the first frame element 4 and can then be adjusted in height in a known manner by packing material for the street pavement under its flange 18. Due to the design described above of this flange 18, the opening to the well can be placed very close to a vertical edge surface. Fig. 1 shows two outer positions of the frame elements 4 and 12, one with solid lines, the other with dash-dotted lines. Patent claims
