Description
Oppfinnelsens område Field of the invention
Foreliggende oppfinnelse vedrører en innretning for å justere høyden av en kum. The present invention relates to a device for adjusting the height of a sump.
Bakgrunn Background
Uttrykket kum omfatter ordinære kummer for vann, avløp og kabler, samt andre nedganger for å betjene nedgravde funksjoner, og spesielt kummer som er anord-net i et gatelegeme, vei eller plass, hvor stedet er belagt med asfalt, betong eller heller. En kum består ofte av et kumlegeme av betong som er gravd ned i bakken og hvor det er tilkoblet rør eller ganger. Pa toppen av kumlegemet er det som of-test plassert en kumramme som bærer kumlokket. Kumrammen er laget av støpejern og rammen eller veien er tilpasset slik at oversiden av rammen ligger jevnt med veien. Ved nyanlegg er det imidlertid fare for setninger i veien, slik at massene synker sammen. Likeledes kan overflaten av veien heve seg under vinteren pga. tele i det øverste laget av veien, mens kummen vil holde seg i ro ettersom den går ned til frostfri grunn. Dette vil skape en høydeforskjell mellom veien og kummen, og også bryte opp asfalten inntil kummen. Høyden av kummen må også justeres ved reasfaltering av veien, for eksempel ved å bytte ut kumrammen eller legge på mellomringer. Det er også laget kummer hvor kumrammen stikker ned i det underliggende kumlegemet, og slik kan gli opp og ned i kummen i takt med veien (flytende kumramme). The term sump includes ordinary sumps for water, drains and cables, as well as other downs to serve buried functions, and especially sumps that are arranged in a street body, road or space, where the place is paved with asphalt, concrete or slabs. A sump often consists of a sump body made of concrete that is dug into the ground and to which pipes or ducts are connected. On top of the sump body, there is usually a sump frame which carries the sump lid. The sump frame is made of cast iron and the frame or road is adapted so that the top of the frame lies flush with the road. With new construction, however, there is a risk of settlements in the road, so that the masses sink together. Likewise, the surface of the road can rise during the winter due to tele in the top layer of the road, while the basin will stay still as it descends to frost-free ground. This will create a height difference between the road and the basin, and also break up the asphalt next to the basin. The height of the sump must also be adjusted when the road is reasphalted, for example by replacing the sump frame or adding intermediate rings. Basins have also been made where the sump frame protrudes into the underlying sump body and can thus slide up and down in the sump in step with the road (floating sump frame).
I EP2128344 er det beskrevet en fremgangsmåte for å renovere en kum når det legges ny asfalt rundt kummen. Fremgangsmåten omfatter at kumrammen løftes av kumtoppen og renses for rust og gammel asfalt. Deretter legges det ei kompressibel pakning rundt kumrammen. Kumrammen settes så ned i kummen igjen, med pakningen hvilende mot toppen av kumlegemet. Det sprøytes inn et støpemateriale i hulrommet mellom kumrammen og omgivende asfalt, og kumrammen senkes deretter ned til korrekt posisjon i forhold til veien. Dette er mulig siden pakningen er kompressibel og kan trykkes sammen ved behov. Kumrammen vil da være festet til veiens topplag, og gli fritt innenfor kumtoppen. Kumrammen vil flyte fritt i takt med at veien hever og senker seg. EP2128344 describes a method for renovating a sump when new asphalt is laid around the sump. The procedure includes the sump frame being lifted from the sump top and cleaned of rust and old asphalt. A compressible gasket is then placed around the sump frame. The sump frame is then placed back into the sump, with the gasket resting against the top of the sump body. A molding material is injected into the cavity between the sump frame and surrounding asphalt, and the sump frame is then lowered to the correct position in relation to the road. This is possible since the gasket is compressible and can be pressed together if necessary. The sump frame will then be attached to the top layer of the road, and slide freely within the sump top. The sump frame will float freely as the road rises and falls.
Fra Fl 580 Ul er det kjent en løsning med en adapterring som hviler på kumtoppen. Krefter vil overføres fra kumrammen til adapterringen pga. massen som ligger inntil begge, og også fra overliggende masser, og videre til kumtoppen. I praksis vil man få problemer mht. setninger og tele. Lignende løsninger er også kjent fra WO 2004/085750 og SE 430998. From Fl 580 Ul, a solution with an adapter ring that rests on the sump top is known. Forces will be transferred from the sump frame to the adapter ring due to the mass that lies next to both, and also from overlying masses, and on to the sump top. In practice, there will be problems with sentences and tele. Similar solutions are also known from WO 2004/085750 and SE 430998.
DE 102006056936 viser en løsning hvor det er lagt inn en støpemasse mellom kumtopp og veibane. Det benyttes mellomringer for å justere høyden av kumrammen. Det er dermed en kontinuerlig forbindelse fra kumlokket og helt ned til frostfri grunn. Med denne løsningen vil kumrammen holde seg i ro under vinteren, men veien rundt vil heve seg i området utenfor støpemassen. DE 102006056936 shows a solution where a molding compound is inserted between the sump top and the road surface. Spacers are used to adjust the height of the sump frame. There is thus a continuous connection from the manhole cover all the way down to the frost-free ground. With this solution, the sump frame will remain stable during the winter, but the road around it will rise in the area outside the casting mass.
CN 202627025 U beskriver en kum med en kumramme med adapterring som hviler på kumtoppen. Eventuell tele vil løfte kumrammen fra kumtoppen. CN 202627025 U describes a basin with a basin frame with an adapter ring resting on the basin top. Any tele will lift the sump frame from the sump top.
Ved asfaltering av en vei, og spesielt ei bygate, er det viktig at installeringen og avrettingen av kumrammen kan skje hurtig. Et gateløp må ofte asfalteres nattetid, når det er lite trafikk og gaten kan stenges. Så snart asfaltleggerne har passert blir kumrammene tatt opp, renset eller byttet, og satt ned igjen i korrekt høyde. When paving a road, and especially a city street, it is important that the installation and leveling of the sump frame can be done quickly. A street race often has to be paved at night, when there is little traffic and the street can be closed. As soon as the asphalt pavers have passed, the sump frames are taken up, cleaned or replaced, and put back down at the correct height.
Sammenfatning av oppfinnelsen Summary of the Invention
Foreliggende oppfinnelse har som formål å fremskaffe en fremgangsmåte for avret-ting av en kumramme, samt en innretning spesielt utformet for denne fremgangsmåten, som er enklere og enda raskere å utføre enn kjente fremgangsmåter. The purpose of the present invention is to provide a method for straightening a sump frame, as well as a device specially designed for this method, which is simpler and even faster to perform than known methods.
Dette oppnås med en fremgangsmåte og innretning slik det fremgår av de etterføl-gende patentkrav. This is achieved with a method and device as is apparent from the subsequent patent claims.
Nærmere bestemt omfatter oppfinnelsen en fremgangsmåte for installasjon eller renovasjon av en kum i forhold til en overflate, hvor kummen omfatter i det minste et kumlegeme med kumtopp, kumramme og kumlokk. Et første trinn i fremgangsmåten omfatter å løfte kumrammen opp fra kumlegemet til en første posisjon. Deretter blir det plassert en forskalingsring rundt kumtoppen slik at forskalingsringen hviler på masse utenfor kumtoppen, hvoretter kumrammen senkes til en andre posisjon hvor kumrammen er innrettet på nivå med nevnte overflate, idet kumrammen løper gjennom nevnte forskalingsring og ned i kumlegemet, før en støpemasse injiseres i et hulrom mellom omgivende grunn og kumrammen. Ved denne fremgangsmåten sikres det at kumrammen ikke festes til kumtoppen og at den derfor alltid kan bevege se uavhengig av selve kumlegemet. More specifically, the invention includes a method for installing or renovating a sump in relation to a surface, where the sump comprises at least a sump body with sump top, sump frame and sump lid. A first step in the method comprises lifting the sump frame up from the sump body to a first position. A formwork ring is then placed around the sump top so that the formwork ring rests on mass outside the sump top, after which the sump frame is lowered to a second position where the sump frame is aligned at the level of said surface, with the sump frame running through said formwork ring and down into the sump body, before a molding compound is injected into a cavity between the surrounding soil and the sump frame. This method ensures that the sump frame is not attached to the sump top and that it can therefore always move independently of the sump body itself.
Oppfinnelsen omfatter også en forskalingsring for anvendelse ved installasjon eller renovasjon av en kum i forhold til en overflate, hvor kummen omfatter i det minste et kumlegeme med kumtopp, kumramme og kumlokk. Forskalingsringen omfatter et ringformet skjørt og en innover vendende flens festet til en ende av skjørtet, idetflensen er innrettet til å slutte tett rundt kumrammen. Skjørtet er videre dimensjonert slik at det rager utenfor kumtoppen og er innrettet til å hvile på masse utenfor kumtoppen. Forskalingsringen sikrer at det blir et hulrom mellom kumrammen og kumtoppen. The invention also includes a formwork ring for use when installing or renovating a sump in relation to a surface, where the sump comprises at least a sump body with sump top, sump frame and sump lid. The formwork ring comprises an annular skirt and an inward facing flange attached to one end of the skirt, the flange being arranged to close tightly around the sump frame. The skirt is further dimensioned so that it protrudes outside the sump top and is arranged to rest on mass outside the sump top. The formwork ring ensures that there is a cavity between the sump frame and the sump top.
Forskalingsringen kan videre omfatte en pakning festet til en indre omkrets av flensen. Denne sikrer at det ikke trenger ned støpemasse mellom kumrammen og forskalingsringen. The formwork ring may further comprise a gasket attached to an inner circumference of the flange. This ensures that no molding compound penetrates between the sump frame and the formwork ring.
Det nevnte skjørtet på forskalingsringen kan være sylindrisk. Dette kan tillate noe bevegelse mellom forskalingsringen og kumlegemet. Said skirt of the formwork ring may be cylindrical. This may allow some movement between the formwork ring and the sump body.
Alternativt kan skjørtet være konisk. Dette gjør at forskalingsringene kan stables og derved lettere transporteres. Alternatively, the skirt can be conical. This means that the formwork rings can be stacked and thus transported more easily.
Forskalingsringen kan være dannet av et metall, et fibermateriale eller en polymer. Forskalingsringen må ha styrke nok til å beholde formen når støpemassen injiseres og ellers være rimelig å produsere. Det kan være fordelaktig å produsere ringen i et fibermateriale hvis man ønsker at ringen skal dekomponeres når støpeprosessen er ferdig. The formwork ring can be formed from a metal, a fiber material or a polymer. The formwork ring must have enough strength to retain its shape when the molding compound is injected and otherwise be reasonable to manufacture. It can be advantageous to produce the ring in a fiber material if you want the ring to decompose when the casting process is finished.
Ifølge en utførelsesform av oppfinnelsen er skjørtet og flensen dannet av et stivt polymermateriale og pakningen er i form av ei leppe dannet av et fleksibelt polymermateriale, idet forskalingsringen er tildannet i et stykke. Dette tillater en kost-nadseffektiv produksjon av ringen. Leppa vil slutte tett rundt flensen på kumrammen og bøyes nedover når denne settes på. According to one embodiment of the invention, the skirt and the flange are formed from a rigid polymer material and the gasket is in the form of a lip formed from a flexible polymer material, the formwork ring being formed in one piece. This allows a cost-effective production of the ring. The lip will close tightly around the flange of the sump frame and bend downwards when this is fitted.
Forskalingsringen kan også tildannes slik at flensen danner en separat flat skive med et spor langs ytterkanten, idet skjørtet er i form av en flat sidevegg som er innrettet til å bøyes til og sneppes inn i sporet. Dette tillater at ringen kan transporteres flatpakket, og først settes sammen på bruksstedet. The formwork ring can also be formed so that the flange forms a separate flat disk with a groove along the outer edge, the skirt being in the form of a flat side wall which is arranged to be bent and snapped into the groove. This allows the ring to be transported flat packed and first assembled at the point of use.

Detaljert beskrivelse Detailed description
Fig. 1 viser en kum bestående av et kumlegeme 1 med kumtopp 2 som er installert i grunnen. Over grunnmassen 3 er det lagt et lag med drenerende pukk 4. På pukken er det anlagt en vei med lag av asfalt 5 og underlag 6. Gjennom overflatelagene 5 og 6 løper det en kumramme 7 med flens 8 og lokk 9. Kumrammen er festet i overflatelagene, men er ment å gli fritt inne i kumlegemet 1, dvs. at kumrammen er av den flytende typen. Dette virker ikke alltid som beregnet, idet masse legger seg inntil kumrammen slik at det ikke er rom for å sige ned. Dersom veibanen hever seg, for eksempel på grunn av frost, vil det skape et tomrom, hvorpå belast-ningen på rammen (fra trafikken) vil presse den ned i tomrommet og dermed skape ujevnhet mellom veibane og kumramme. I dette tilfelle har kumrammen sunket ned og må nå flyttes opp slik at den kommer i rett nivå i forhold til veiens overflate 10. Fig. 2 viser den samme kummen. Kumrammen er nå fjernet (og renset for gammel asfalt og rust), mens kanten av åpningen i veibanen er avrettet og forberedt for reinstallasjoin av kumrammen. Fig. 3 viser at det legges ned en innretning, en forskalingsring 11 i åpningen. Forskalingsringen 11 ligger på pukken utenfor kumlegemet. Fig. 1 shows a sump consisting of a sump body 1 with a sump top 2 which is installed in the ground. A layer of draining crushed stone 4 has been laid over the base mass 3. On the crushed stone, a road has been laid with a layer of asphalt 5 and substrate 6. Through the surface layers 5 and 6 runs a sump frame 7 with flange 8 and lid 9. The sump frame is fixed in the surface layers, but is meant to slide freely inside the sump body 1, i.e. that the sump frame is of the floating type. This does not always work as planned, as mass settles close to the sump frame so that there is no room for it to settle down. If the road surface rises, for example due to frost, it will create a void, whereupon the load on the frame (from the traffic) will push it down into the void and thus create unevenness between the road surface and the sump frame. In this case, the sump frame has sunk down and must now be moved up so that it is at the right level in relation to the road surface 10. Fig. 2 shows the same sump. The sump frame has now been removed (and cleaned of old asphalt and rust), while the edge of the opening in the roadway has been leveled and prepared for re-installation of the sump frame. Fig. 3 shows that a device, a formwork ring 11, is placed in the opening. The formwork ring 11 lies on the screed outside the sump body.
I Fig. 4 er kumrammen senket ned i åpningen og ligger i rett nivå i forhold til veibanen. Det benyttes et eget redskap eller maskin til dette (ikke vist). Kumramma styres ned i kumlegemet av forskalingsringen 11. Deretter injiseres støpemasse 12 inn i tomrommet utenfor kumringen, mens kumrammen ligger i det nevnte rette nivået. Forskalingsringen holder støpemassen vekk fra de nedre områder av rammen, og sikrer således at massen ikke kleber til kumrammen i området der den går ned i kumlegemet, mens støpemassen samtidig limer kumrammen fast til de øvre lagene av veibanen. Så snart massen har herdet kan det nevnte redskapet fjernes og installasjonen av kumrammen er ferdig. Fig. 5a viseren mulig utforming av forskalingsringen 11. Forskalingsringen består av et skjørt 111, en innover vendende flens 112 festet i en (øvre) ende av skjørtet 111, samt ei pakning 113 festet til den indre omkretsen av flensen 112. Pakningen kan være løs og bare presset fast på flensen 112. Hensikten med pakningen er å hindre støpemasse for å trenge ned mellom kumramma og forskalingsringen og inn i hulrommet inne i forskalingsringen. Ringen er her rent sylindrisk i form, og kan lages i dimensjoner som passer standardiserte kummer, dvs. at ringen slutter tett til omkretsen av kumtoppen. Forskalingsringen kan være satt sammen av flere de-ler eller støpt i ett stykke, og kan være dannet av ethvert egnet materiale, det være seg metall, et fibermateriale eller en polymer. Forskalingsringen kan også være uten pakning, i tilfelle den slutter tett nok til kumlegemet, eller at støpemas-sen er av en beskaffenhet som tillater dette. Forskalingsringen kan også produseres i plast i ett stykke, fortrinnsvis slik at skjørtet og flensen er dannet av en relativt stiv plast, mens pakningen er dannet av et mer elastisk plastmateriale som danner ei leppe som vender innover i ringen. Fig. 5b viser en annen utførelse av forskalingsringen, hvor skjørtet 111 er konisk. Den største fordelen med denne utførelsen er at den gjør det mulig å stable ringe-ne, slik at de tar mindre plass. In Fig. 4, the sump frame is lowered into the opening and lies at the right level in relation to the roadway. A separate tool or machine is used for this (not shown). The sump frame is guided down into the sump body by the formwork ring 11. Next, molding compound 12 is injected into the void outside the sump ring, while the sump frame lies in the aforementioned correct level. The formwork ring keeps the molding compound away from the lower areas of the frame, and thus ensures that the compound does not stick to the sump frame in the area where it goes down into the sump body, while the molding compound simultaneously glues the sump frame firmly to the upper layers of the roadway. As soon as the mass has hardened, the aforementioned tool can be removed and the installation of the sump frame is complete. Fig. 5a shows a possible design of the formwork ring 11. The formwork ring consists of a skirt 111, an inward-facing flange 112 attached to an (upper) end of the skirt 111, and a gasket 113 attached to the inner circumference of the flange 112. The gasket can be loose and just pressed firmly onto the flange 112. The purpose of the gasket is to prevent molding compound from penetrating down between the sump frame and the formwork ring and into the cavity inside the formwork ring. The ring here is purely cylindrical in shape, and can be made in dimensions that suit standardized basins, i.e. the ring closes tightly to the circumference of the basin top. The formwork ring can be assembled from several parts or cast in one piece, and can be formed from any suitable material, be it metal, a fiber material or a polymer. The formwork ring can also be without a gasket, in the event that it joins the sump body tightly enough, or that the molding compound is of a nature that allows this. The formwork ring can also be produced in one piece of plastic, preferably so that the skirt and flange are formed from a relatively rigid plastic, while the gasket is formed from a more elastic plastic material that forms a lip that faces inwards into the ring. Fig. 5b shows another embodiment of the formwork ring, where the skirt 111 is conical. The biggest advantage of this design is that it makes it possible to stack the rings, so that they take up less space.
Forskalingsringen kan også lages som et byggesettsystem, med en flat skive som danner flensen, og en rett sidevegg som bøyes til og deretter sneppes på plass i et spor langs ytterkant av skiven (ikke vist). Dette gjør det enklere å lagre og trans-portere kumringene. The formwork ring can also be made as a kit system, with a flat disc forming the flange, and a straight sidewall which is bent and then snapped into place in a groove along the outer edge of the disc (not shown). This makes it easier to store and transport the drum rings.
Forskalingsringen kan for den del være av forskjellig form, dvs. utformet som en rund ring, eller en kvadratisk eller rektangulær ring, eller enhver annen form som passer til utseendet av kumtoppen og kumrammen. The formwork ring can therefore be of different shape, i.e. designed as a round ring, or a square or rectangular ring, or any other shape that suits the appearance of the sump top and the sump frame.
