Foreliggende oppfinnelse vedrører en anordning ved avløps-brønner som har en innløpsdel og minst ett fra innløpsdelen siderettet utgående utløpsrør,"og hvor det i innløpsdelen er monterbart anbrakt en innsats som dels er uttagbar fra innløpsdelen, dels innbefatter en vannlåstunge og dels har minst ett innløps-parti forsynt med minst en øvre innløpsåpning og minst en nedre gjonnomstrømningsåpning sorn oventil er begrenset av vannlåstun-. gens underkant. The present invention relates to a device for drainage wells which has an inlet part and at least one outlet pipe exiting laterally from the inlet part, and where in the inlet part an insert can be mounted which is partly removable from the inlet part, partly includes a water lock tongue and partly has at least one inlet - part provided with at least one upper inlet opening and at least one lower through-flow opening so that the top is limited by the lower edge of the water lock tongue.

Når det gjelder avløpsbrønnsr av ovennevnte typa, stilles det nu store krav til forskjellige egenskaper så som kompakthet, lav konstruksjon, total rensbarhet, strømningsriktig dg trykk-variasjonsriktig utformning,, samtidig som brønnene skal være ' enkle, lette å tilslutte, tåle varm9 og ha nødvendig vannlåshøyde°g gjennomslipningsevne. When it comes to drainage wells of the above type, great demands are now placed on various properties such as compactness, low construction, total cleanability, flow-correct and pressure-variation-correct design, at the same time that the wells must be 'simple, easy to connect, withstand heat9 and have required water trap height°g penetration ability.

Ved kjente avløpsbrønner av nevnte type er en del av disse egenskaper vel utviklet, mens andre brønner har utilfredsstil-lende egenskaper. In the case of known drainage wells of the aforementioned type, some of these properties are well developed, while other wells have unsatisfactory properties.

Formålet med foreliggende oppfinnelse er at ved avløpsbrøn-ner av innledningsvis angitte type å frembringe en anordning som med enkle midler forbedrer en del av nevnte egenskaper som tid-ligere var utilstrekkelige, uten derved å forringe brønnens andra egenskaper. Ifølge oppfinnelsen løses detta i hovedsaken ved at innsatsens gjennomstrømningsåpning nedentil sr begrenset av et veggparti av en med vannlåstungen forbundet og innsatsens inn-løpsparti fra innløpsdelen avskjermende vegg, hvilket veggparti er beliggende på et lavere nivå enn utløpsrørets laveste del. The purpose of the present invention is to produce a device for drainage wells of the type indicated at the outset which, by simple means, improves some of the aforementioned properties which were previously insufficient, without thereby impairing the well's other properties. According to the invention, this is mainly solved by the bottom of the insert's flow opening being limited by a wall part of a wall connected to the water lock tongue and shielding the inlet part of the insert from the inlet part, which wall part is located at a lower level than the lowest part of the outlet pipe.

Oppfinnelsen3kal nedenfor beskrives nærmere med henvis-ning til vedføyde tegninger, hvor: Fig. 1 viser i snitt en avløpsbrønn med sn anordning i hen-hold til oppfineelsen. Fig. 2 viser i snitt en alternativ utførelse av avløps-brønnen. The invention will be described in more detail below with reference to the attached drawings, where: Fig. 1 shows a cross-section of a drainage well with the following arrangement according to the invention. Fig. 2 shows in section an alternative design of the drainage well.

Fig. 3 visar et snitt III-III i figo2.Fig. 3 shows a section III-III in figo2.

Fig. 4 og 5 viser i snitt partier av avløpsbrønner med forskjellig utforming av søter og snepportfatninger. Figs 4 and 5 show, in average, parts of drainage wells with different designs of sluices and trapdoor sockets.

Avløpsbrønnen som er illustrert i figurene, fremviser en innløpsdel 1 med minst ett fra denne siderettet utgående utløps-rør 2. I innløpsdelen 1 er monterbart anbrakt en innsats 3 som dels er uttagbar, dels innbefatter en vannlåstunge 4 og dels fremviser et innløpsparti 5 forsynt med minst en øvre innløps-åpning 6 og minst en nedre gjennomstrømningsåpning 7 som oventil er begrenset av vannlåstungens 4 underkant 8. The drain well that is illustrated in the figures shows an inlet part 1 with at least one side-directed outlet pipe 2 from this side. In the inlet part 1, an insert 3 is mountably placed which is partly removable, partly includes a water lock tongue 4 and partly presents an inlet section 5 provided with at least one upper inlet opening 6 and at least one lower through-flow opening 7 which is limited above by the lower edge 8 of the water lock tongue 4.

For at man ved brønnen med ovennevnte innsats 3 dels skal kunne rense utløpsrøret 2 effektivt, dels skal kunne oppnå lav totalhøyde på brønnBn undBr bibehold av nødvendig vannlåshøyde og dessuten oppnå best mulig gjennomstrømningseffekt og trykk-variasjonseffekt, sr innsatsens 3 gjennomstrømningsåpning 7 nedentil begrenset av et veggparti 9 av en med vannlåstungen 4 forbundet og innsatsens 3 innløpsparti 5 fra innløpsdelen 1 avskjermende vegg 10, hvilket veggparti 9 er beliggende på et lavere nivå 11 enn utløpsrørets 2 laveste del 12. In order for the well with the above-mentioned insert 3 to partly be able to clean the outlet pipe 2 effectively, partly to be able to achieve a low overall height of the wellBn andBr to maintain the necessary water trap height and also to achieve the best possible flow-through effect and pressure-variation effect, the flow-through opening 7 of the insert 3 is limited below by a wall part 9 of a wall 10 that is connected to the water lock tongue 4 and the inlet part 5 of the insert 3 from the inlet part 1 shielding wall 10, which wall part 9 is situated at a lower level 11 than the lowest part 12 of the outlet pipe 2.

Strømningen gjennom innsatsen 3 og skjermens 13 avskjermning mot bakvann kan gjøres effektiv ved at det skjermdannénde veggpartiet 13 utgjøres av sn under vannlåstungen 4 beliggende, med utstrømningsåpning 14 forsynt del av en skålformet yttervegg av innsatsen 3. The flow through the insert 3 and the shielding of the screen 13 against backwater can be made effective by the screen-forming wall part 13 being made up of sn under the water lock tongue 4, provided with an outflow opening 14 part of a bowl-shaped outer wall of the insert 3.

Spesielt god avskjermning mot bakvann kan oppnås ved at. det skjermdannénde veggpartiet 13 i det minste nedentil i ut-løpsrørets 2 munning heller og danner en lomme 15 nedenfor innsatsens 3 utstrømningsåpning 14. Particularly good shielding against backwater can be achieved by the screen-forming wall part 13 at least at the bottom of the mouth of the outlet pipe 2 rather and forms a pocket 15 below the outflow opening 14 of the insert 3.

I visse tilfelle kan det ut fra strømnings-, fremstillings-og stabilitetssynspunkt være fordelaktig å la innsatsens 3 veggparti 9 munne ut innved en i innløpsdelen 1 utformet skjermvegg 16 som avskjermer utløpsrørets 2 indre mBd unntak av en utstrøm-ningsåpning 17 som tillater utstrømning til utløpsrørets 2 øvre del. In certain cases, from the point of view of flow, manufacturing and stability, it can be advantageous to let the wall part 9 of the insert 3 open out into a screen wall 16 formed in the inlet part 1 which shields the inner mBd of the outlet pipe 2 with the exception of an outflow opening 17 which allows outflow to the outlet pipe's 2 upper part.

For ved denne utførelse å oppnå best mulig avskjermnings-effekt mot bakvann, kan skjermveggen 16 være forbundet med en del 18 av innløpsdelen 1 som ligger på et lavere nivå enn ut- løpsrørets 2 laveste del 12 til danning av en lomme 19 hvis laveste del ligger på et lavere nivå enn utløpsrørets 2 laveste del 12. In order to achieve the best possible shielding effect against backwater with this design, the screen wall 16 can be connected to a part 18 of the inlet part 1 which is at a lower level than the lowest part 12 of the outlet pipe 2 to form a pocket 19 whose lowest part lies at a lower level than the lowest part 12 of the outlet pipe 2.

Den i innløpsdelen 1 utformede skjermveggsn 16 skyter inn som en oventil åpen forlengning av utløpsrøret 2 i en del av inn-løpsdelen 1 som dels er bredere enn forlengningen, dels er beliggende bak vannlåstungen 4. Som følge herav kan skjermveggsn 1S ligge nær vannlåstungen 4 uten at disse deler danner en strupning som vesentlig nedsetter strømningseffekten. Ut fra tilvirkningssynspunkt er det fordelaktig å utforme forlengningen slik at den dels fremviser to med hverandre og i hovedsaken også med utløpsrørets 2 lengdeakse parallelle vegger 20 og dels fremviser en endevegg 21 som forbinder de parallelle vegger 20. The screen wall section 16 formed in the inlet part 1 shoots in as an upwardly open extension of the outlet pipe 2 in a part of the inlet part 1 which is partly wider than the extension, and partly located behind the water lock tongue 4. As a result of this, the screen wall section 1S can lie close to the water lock tongue 4 without that these parts form a bottleneck which significantly reduces the flow effect. From a manufacturing point of view, it is advantageous to design the extension so that it partly presents two walls 20 parallel to each other and, in the main, also to the longitudinal axis of the outlet pipe 2, and partly presents an end wall 21 which connects the parallel walls 20.

For å utforme innsatsen 3 med spesielt hensiktsmessig ut-førte strømningsvegger og innløpsdelen 1 spesielt stabilt, kan innsatsen 3 fremvise en yttervegg 10 som oventil forløper i hovedsaken vertikalt og via en jevn bue går over i i hovedsaken horisontal retning, mens innløpsdelen 1 utenfor nevnte vegg 10 av innsatsen 3 forløper i hovedsaken vertikalt nedover for nedentil via et hjørneparti 22 å gå over i et plant nedre veggparti 18. In order to design the insert 3 with particularly appropriately designed flow walls and the inlet part 1 particularly stable, the insert 3 can present an outer wall 10 which runs mainly vertically at the top and transitions via a smooth arc into a mainly horizontal direction, while the inlet part 1 outside said wall 10 of the insert 3 mainly proceeds vertically downwards to transition below via a corner section 22 into a flat lower wall section 18.

Innsatsen 3 kan holdes fast i innløpsdelen 1 på en enkel og hensiktsmessig måte ved at innløpsdelen 1 oventil fremviser et sete 23 mot hvilket et øvre parti 24 av innsatsen 3 ligger an via et tetningsorgan 25. The insert 3 can be held firmly in the inlet part 1 in a simple and appropriate way by the inlet part 1 showing a seat 23 at the top against which an upper part 24 of the insert 3 rests via a sealing means 25.

Innløpsdelens 1 sete 23 for innsatsen 3 kan ligge nærmere sentrum av innløpsdelens 1 øvre åpning enn et annet i innløps-delen 1 utformet sete 26 som er innrettet til å danne anleggsflate for klemringer 27 for fastklemming av belegg 29 og/eller forhøyningsringer, slik at innsatsen 3 kan plasseres i eller tas ut av innløpsdelen 1 uten at monterte ringer 27 hindrer dette. The inlet part 1's seat 23 for the insert 3 can be located closer to the center of the inlet part 1's upper opening than another seat 26 designed in the inlet part 1, which is designed to form a contact surface for clamping rings 27 for clamping the coating 29 and/or elevation rings, so that the insert 3 can be placed in or taken out of the inlet part 1 without mounted rings 27 preventing this.

For å kunne montere og demontere innsatsen 3 hurtig, kan innløpsdelen 1 og innsatsen 3 fremvise hurtigfatningspartier 30 og 31 som samvirker med hverandre når innsatsen 3 plasseres i innløpsdelen 1. Hurtigfatningspartiene kan dannes dels av gripepartier 30 som rager frem fra innløpsdelens 1 vegg og dels av. spor og/eller anslagskanter 31 i innsatsen 3. In order to be able to assemble and disassemble the insert 3 quickly, the inlet part 1 and the insert 3 can present quick-fitting parts 30 and 31 which cooperate with each other when the insert 3 is placed in the inlet part 1. The quick-fitting parts can be formed partly by gripping parts 30 that protrude from the wall of the inlet part 1 and partly by . grooves and/or stop edges 31 in the insert 3.

Ovenfor beskrevne og på tegningene eksemplifiserte utfø-relaeseksempler er ment å forklare oppfinnelsen men ikke å be- grense oppfinnelsesprinsippet slik som dette defineres i etter-følgende patentkrav. The execution examples described above and exemplified in the drawings are intended to explain the invention but not to limit the inventive principle as defined in subsequent patent claims.
