Description

Foreliggende oppfinnelse angår en injeksjonsslange f.or kjemisk injeksjon i betong. The present invention relates to an injection hose for chemical injection into concrete.

Det er kjent at betongkonstruksjoner som står under vanntrykk stiller store krav til utførelsen av betongstøpen generelt og spesielt store krav må stilles til betongfugene. It is known that concrete structures that are under water pressure place great demands on the execution of the concrete casting in general and particularly great demands must be placed on the concrete joints.

Den ideelle fuge mellom to betongstøp ønskes oppnådd uten riss, sprekker, steinreir og lignende. The ideal joint between two concrete castings should be achieved without cracks, cracks, stone nests and the like.

Imidlertid vil dette i praksis være så og si umulig på grunn av manglende homogenitet i betongen og også på grunn av den krymping som oppstår ved betongens avbinding. However, in practice this will be virtually impossible due to a lack of homogeneity in the concrete and also due to the shrinkage that occurs when the concrete sets.

De oppståtte sprekker og riss søker man så å tette i efterhånd og en måte for slik tetting er ved punktvis injeksjon i betongfugene. The resulting cracks and fissures are then sought to be sealed afterwards, and one way of such sealing is by spot injection into the concrete joints.

Denne metode er imidlertid usikker og også meget kostbar. However, this method is uncertain and also very expensive.

Man har derfor søkt å finne bedre metoder for tetting av betongfuger og det system som i dag generelt benyttes er et injeksjonssystem som er basert på perforerte slanger som forløper i betongfugens lengderetning og der et tette-materiale, vanligvis et tokomponent polyuretanmateriale, sprøytes inn i slangene og fordeles i fugen ved hjelp av perforeringene med efterfølgende herding og tetting. People have therefore sought to find better methods for sealing concrete joints and the system that is generally used today is an injection system which is based on perforated hoses that run in the longitudinal direction of the concrete joint and where a sealing material, usually a two-component polyurethane material, is injected into the hoses and distributed in the joint using the perforations with subsequent curing and sealing.

Dette systemet legges på forhånd og man sparer derfor den meget tidkrevende og kostbare gjennomboring av betongkonstruksjonen . This system is laid in advance and therefore the very time-consuming and expensive drilling of the concrete structure is saved.

Kjent på markedet er fleksible stålslanger som er omviklet av et eller flere lag tekstilduk. Known on the market are flexible steel hoses that are wrapped in one or more layers of textile fabric.

Dukens formål er å hindre at betongmassen ved støping tetter perforeringen i fordelingsslangen for herdematerialet, til dette formål har imidlertid tekstilduk vist seg ugunstig da duken i seg selv er et flateelement som ved støping ble tettet slik at injeksjonsmasse ikke slapp ut av den perforerte slange for tetting av oppståtte risser og sprekker. The purpose of the cloth is to prevent the concrete mass during casting from sealing the perforation in the distribution hose for the curing material, for this purpose, however, textile cloth has proven unfavorable as the cloth itself is a surface element that was sealed during casting so that injection compound did not escape from the perforated hose for sealing of resulting cracks and fissures.

Senere utvikling og forskning på området har ført til det system som i dag markedsføres under varemerket "FUKO®". Later development and research in the area has led to the system that is today marketed under the trademark "FUKO®".

Dette system omfatter en slangekjerne av et fast og sterkt materiale langs hvilket det i lengderetning er anordnet spor i hvis bunn det i sin tur er tildannet gjennomgående perforeringer. This system comprises a hose core made of a firm and strong material along which grooves are arranged longitudinally in the bottom of which in turn perforations are formed throughout.

Disse spor er dekket av løstliggende lameller slik at slangens totale profil er tilnærmet sirkulær. These grooves are covered by loose lamellas so that the hose's overall profile is approximately circular.

Formålet med disse lameller er å hindre at betongmassen som støpes tetter slangens perforeringer samtidig som de sikrer at inj eksj onsmasse selv ved lavt trykk kan presses ut av mateslangen og inn i de omliggende riss og sprekker. The purpose of these lamellas is to prevent the concrete mass that is cast from sealing the perforations of the hose while at the same time ensuring that the injection mass can be pushed out of the feed hose even at low pressure and into the surrounding cracks and crevices.

Det kjente "FUKO®"-system er så til slutt utstyrt med en omliggende vevet, åpen plaststrømpe for å holde de langs-gående lameller på plass. The well-known "FUKO®" system is then finally equipped with a surrounding woven, open plastic stocking to hold the longitudinal slats in place.

Dette system er teknisk meget pålitelig og brukssikkert men har den mangel at det er relativt komplisert å produsere og også meget kostbart. This system is technically very reliable and safe to use, but has the disadvantage that it is relatively complicated to produce and also very expensive.

Denne pris rettferdiggjør derfor bruk kun i de tilfeller der de angjeldende betongkonstruksjoner står under permanent vanntrykk og derfor må sikres. This price therefore justifies use only in cases where the concrete structures in question are under permanent water pressure and must therefore be secured.

I et meget stort antall konstruksjoner vil risikoen for vanntrykk utenfor betongkonstruksjonen kun være periodisk og sågar kun ventes relativt sjelden, eksempler på dette er for eksempel springflodområder eller andre mer eller mindre periodisk men svært sjeldent oversvømmede områder. In a very large number of constructions, the risk of water pressure outside the concrete construction will only be periodic and even only expected relatively rarely, examples of this are, for example, flash flood areas or other more or less periodically but very rarely flooded areas.

Det kan her være på sin plass å benytte et system med rimelig brukssikkerhet men som er enkelt og lett å produsere og som derved også er meget rimelig i anskaffelse og bruk. It may be appropriate here to use a system with reasonable safety of use, but which is simple and easy to produce and which is therefore also very reasonable in acquisition and use.

Foreliggende oppfinnelse tar sikte på å tilveiebringe et slikt rimelig injeksjonssystem for kjemisk injeksjon i betong og angår derfor en injeksjonsslange av den nevnte type omfattende en sentral, regelmessig perforert mateslange med et over perforeringen løst anordnet dekke med porer eller masker, og denne slange karakteriseres ved at dekket består av et rundt slangens periferi anordnet sammenpressbart hylster med gjennomgående fine porer som lukkes og tettes mot inntrengning utenfra under press ved utstøping av hulrom rundt slangen, idet gjennomtrengning av et tetningsmiddel innenfra kan skje under påfølgende injisering. The present invention aims to provide such a reasonable injection system for chemical injection into concrete and therefore relates to an injection hose of the aforementioned type comprising a central, regularly perforated feed hose with a cover loosely arranged over the perforation with pores or meshes, and this hose is characterized by the tire consists of a compressible casing arranged around the hose's periphery with continuous fine pores which are closed and sealed against penetration from the outside under pressure by casting cavities around the hose, as penetration of a sealant from the inside can occur during subsequent injection.

Fortrinnsvis består dette dekket av en elastisk skumplast eller lignende med gjennomgående fine porer. Preferably, this cover consists of an elastic foam plastic or similar with fine pores throughout.

Som nevnt ovenfor er hensikten med dette dekket over perforeringen å hindre at perforeringen tettes av den påstøpte betongmasse. As mentioned above, the purpose of this cover over the perforation is to prevent the perforation from being sealed by the poured concrete mass.

Dette oppnås ifølge oppfinnelsen ved at dekket ved kontakt med betongen presses sammen og tettes og derved sperrer betongens avgang til perforeringene mens det fremdeles vil forbli åpne kanaler der betongens innvirkning er mindre direkte, slik at injeksjonsmasse slipper ut av perforeringene og kan strømme inn i de riss og sprekker som skal tettes. According to the invention, this is achieved by the tire being pressed together and sealed when it comes into contact with the concrete, thereby blocking the flow of the concrete to the perforations, while there will still remain open channels where the concrete's impact is less direct, so that injection compound escapes from the perforations and can flow into the cracks and cracks to be sealed.

Som mateslange kan det ifølge oppfinnelsen benyttes en konvensjonell tykkvegget plastslange med løpende regelmessig perforering rundt hele omkretsen. According to the invention, a conventional thick-walled plastic hose with continuous regular perforation around the entire circumference can be used as a feeding hose.

Dekket kan, hvis det benyttes en skumplast som materiale, fremstilles ved en påekstrudering. The cover can, if foam plastic is used as material, be produced by extrusion.

En omgivende festestrømpe kan legges på uten at dette er nødvendig. A surrounding support stocking can be put on without this being necessary.

Som materiale i dekket rundt slangen kan man også tenke seg et tett sammenfiltret nett av ett trådprodukt, bestående av tråder med meget fin diameter. As a material in the cover around the hose, one can also imagine a densely tangled net of one wire product, consisting of wires of very fine diameter.

En fintrådet stålull kan for eksempel benyttes. A finely threaded steel wool can be used, for example.

I dette tilfellet kan det være fordelaktig å veve en festestrømpe utenpå mateslangen med det omgivende hylster. In this case, it may be advantageous to weave a retaining stocking on the outside of the feeding tube with the surrounding sleeve.

Oppfinnelsen er illustrert i den ledsagende skisse som viser en injeksjonsslange 1 bestående av en mateslange 2 med både i lengderetning og omkrets regelmessig anordnede perforeringer 3 og rundt hvilken sentrale slange 2 det er anordnet et sammenpressbart dekke 4 med gjennomgående fine porer. The invention is illustrated in the accompanying sketch which shows an injection hose 1 consisting of a feed hose 2 with both longitudinally and circumferentially regularly arranged perforations 3 and around which central hose 2 there is arranged a compressible cover 4 with continuous fine pores.

Produktet ifølge oppfinnelsen er lett og enkelt å fremstille sammenlignet med den kjente teknikk og lar seg derved også fremstille til en langt lavere pris enn de produkter som i dag finnes på markedet med sammenlignbar kvalitet. The product according to the invention is easy and simple to produce compared to the known technique and can thereby also be produced at a much lower price than the products that are currently on the market with comparable quality.

Oppfinnelsens gjenstand tilfredsstiller derfor markedets behov for et rimlig produkt med rimelig sikkerhet, til bruk i alle de steder der vannsikring er nødvendig på grunn av sporadisk risiko for vanntrykk utenfor betongkonstruksjonen, men der hovedhensikten er, om ikke totalt å utestenge vann så i alle fall å forsinke vanninnsig i en slik grad at sikringen står i forhold til den foreliggende risiko. The object of the invention therefore satisfies the market's need for a reasonable product with reasonable safety, for use in all those places where water protection is necessary due to the occasional risk of water pressure outside the concrete structure, but where the main purpose is, if not to completely exclude water, then at least to delay water penetration to such an extent that the protection is in proportion to the risk at hand.
