Abstract
Description
Foreliggende oppfinnelse angår en slange for kjemisk injeksjon i betong, omfattende en injeksjonsmaterial-innføringsdel og et dertil festet, sammenpressbart, porøst materiale. The present invention relates to a hose for chemical injection into concrete, comprising an injection material introduction part and an attached, compressible, porous material.
Det ér kjent at betongkonstruksjoner som står under vanntrykk stiller store krav til utførelse av betongstøpen generelt og til betongfugene spesielt. It is known that concrete structures that are under water pressure place great demands on the execution of the concrete casting in general and on the concrete joints in particular.
Den ideelle fuge mellom to betongstøp ønskes og søkes oppnådd uten riss, sprekker, steinreir og lignende. Problemet med lekkasje kan særlig oppstå når betongvegger støpes på en på forhånd støpt betongsåle. The ideal joint between two concrete castings is desired and sought to be achieved without cracks, cracks, stone nests and the like. The problem of leakage can particularly arise when concrete walls are cast on a pre-cast concrete base.
Ideelle fuger vil imidlertid i praksis være så og si umulig på grunn av en manglende homogenitet i betongen og også, ikke minst, på grunn av den krymping som nødvendigvis oppstår når betongen avbindes. However, ideal joints will be virtually impossible in practice due to a lack of homogeneity in the concrete and also, not least, due to the shrinkage that necessarily occurs when the concrete sets.
De oppståtte sprekker og riss søker man så å tette i efterhånd og teknikken kjenner en lang rekke metoder og innretninger. The resulting cracks and cracks are then sought to be sealed afterwards and the technician knows a wide range of methods and devices.
Den eldste og tidligere oftest benyttede metode for tetting av betongsprekker var punktvis injeksjon i betongfugen. Denne metode er imidlertid usikker og, ikke minst, meget kostbar. The oldest and previously most commonly used method for sealing concrete cracks was spot injection into the concrete joint. However, this method is uncertain and, not least, very expensive.
Man har derfor kontinuerlig søkt å finne bedre metoder for tetting av betongfuger og den metode som i dag generelt benyttes er et injeksjonssystem som er basert på på forskjellige måter perforerte slanger som legges i betongfugens lengderetning og der et tettemateriale, vanligvis et tokomponent-polyuretanmateriale, sprøytes inn i slangene og fordeles i fugen ved hjelp av perforeringene med efter-følgende herding og tetting. People have therefore continuously sought to find better methods for sealing concrete joints and the method that is generally used today is an injection system which is based on variously perforated hoses that are laid in the longitudinal direction of the concrete joint and where a sealing material, usually a two-component polyurethane material, is sprayed into the hoses and distributed in the joint using the perforations with subsequent hardening and sealing.
Som antydet legges dette system på forhånd, før den nye påstøp, og man sparer derfor den meget tidkrevende og kostbare gjennomboring av betongkonstruksjonen. As indicated, this system is laid in advance, before the new pour, and therefore the very time-consuming and expensive drilling of the concrete structure is saved.
Av kjent teknikk på dette området skal det særlig vises til EP "0.125.696-A3 som omfatter én sentral, regelmessig perforert mateslange utenfor hvilken det er anordnet et slangef ormet filtersjikt som i sin tur er omhyllet av et slangeformet, nettlignende beskyttelsessjikt. Of known technology in this area, particular reference should be made to EP "0.125.696-A3 which comprises one central, regularly perforated feed hose outside of which is arranged a hose-shaped filter layer which in turn is enveloped by a hose-shaped, net-like protective layer.
Det skal videre vises til N0-søknad P911086 som beskriver en injeksjonsslange for kjemisk injeksjon i betong omfattende en sentral, regelmessig perforert mateslange med et over perforeringen anordnet dekke, der dette dekket består av et rundt slangens periferi anordnet, sammenpressbart hylster med gjennomgående fine porer. Reference should also be made to N0 application P911086, which describes an injection hose for chemical injection into concrete comprising a central, regularly perforated feed hose with a cover arranged above the perforation, where this cover consists of a compressible casing arranged around the periphery of the hose with fine pores throughout.
Formålet med omhyllingen er å hindre at betongmassen ved støping tetter til perforeringene i fordelingsslangen for herdematerialet. For dette formål har tekstilduk vist seg ugunstig da duken i seg selv er et flateelement som ved støping tettes til slik at injeksjonsmasse ikke slipper ut av den perforerte slange for tetting av oppståtte riss og sprekker. The purpose of the casing is to prevent the concrete mass from sealing the perforations in the distribution hose for the hardening material during casting. For this purpose, textile cloth has proved unfavorable as the cloth itself is a surface element which is sealed during casting so that injection compound does not escape from the perforated hose to seal cracks and crevices.
Senere utvikling og forskning på området har ført til et system som i dag markedsføres under betegnelsen "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. Disse spor er dekket av løstliggende lameller slik at slangens totale profil er tilnærmet sirkulær. Later development and research in the area has led to a system that is today marketed under the designation "FUKO". 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. 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 betongmasse som støpes, tetter slangens perforeringer samtidig som de sikrer at injeksjonsmasse selv ved lavt trykk kan presses ut av mateslangen og inn i de omliggende riss og sprekker. The purpose of these slats is to prevent the concrete mass that is cast from sealing the hose's perforations while at the same time ensuring that the injection mass, even at low pressure, can be pushed out of the feed hose and into the surrounding cracks and crevices.
"FUKO"-systemet er til slutt utstyrt med en omliggende vevet, åpen plaststrømpe for å holde de langsgående lameller på plass. The "FUKO" system is finally equipped with a surrounding woven, open plastic stocking to hold the longitudinal slats in place.
Dette system er teknisk meget pålitelig og meget bruks-sikkert men er, i motsetning til det som beskrives i henhold til det ovenfor nevnte NO P911086, relativt komplisert å produsere og også meget kostbart. This system is technically very reliable and very safe to use but, in contrast to what is described in accordance with the above-mentioned NO P911086, is relatively complicated to produce and also very expensive.
Denne pris som er inherent for de teknisk mest sofistikerte produkter rettferdiggjør kun bruk i de tilfeller der de angjeldende betongkonstruksjoner står under permanent vanntrykk og derfor må sikres. This price, which is inherent to the most technically sophisticated products, only justifies use 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 sjeldent, eksemplet på dette er for eksempel springflodområder eller andre mer eller mindre periodisk men svært sjeldent oversvømmede områder. Slike bruksområder rettferdiggjør bruk av teknisk enklere men allikevel brukssikre systemer som er enkle og lette å produsere og som derved er rimelige i anskaffelse og bruk, for eksempel det ovenfor nevnte NO P911086. In a very large number of constructions, the risk of water pressure outside the concrete structure will only be periodic and even expected to be relatively rare, examples of this being, for example, flash flood areas or other more or less periodically but very rarely flooded areas. Such areas of use justify the use of technically simpler but still reliable systems which are simple and easy to produce and which are therefore reasonable in acquisition and use, for example the above-mentioned NO P911086.
Foreliggende oppfinnelse tar sikte på å forbedre den kjente teknikk dithen at det skal muliggjøres samtidig å sprøyte inn minst to forskjellige komponenter og, ved en senere an-ledning, eventuelt å sprøyte inn ytterligere komponenter hvis dette skulle vise seg nødvendig. The present invention aims to improve the known technique by making it possible to inject at least two different components at the same time and, on a later occasion, possibly to inject further components if this should prove necessary.
Oppfinnelsen er basert på den oppdagelse at kun et inn-sprøytingsløp kan vise seg å være ugunstig og videre på det utgangspunkt at jo bredere det området er over hvilket injeksjonsmassen sprøytes ut, jo bedre sikres tettingen, særlig når injeksjonen skjer fra et element som skal beskrives nærmere nedenfor. The invention is based on the discovery that only an injection run can prove to be unfavorable and further on the basis that the wider the area over which the injection mass is sprayed out, the better the sealing is ensured, especially when the injection takes place from an element to be described more details below.
Foreliggende oppfinnelse angår derfor en slange av den innledningsvis nevnte art og denne slange karakteriseres ved at innføringsdelen omfatter minst to, ved siden av hverandre forløpende, fortrinnsvis i et stykke og i form av bånd støpte, kanaler i hvis ytre vegger det er tildannet mikroåpninger for gjennomløp innenfra og utover under et på The present invention therefore relates to a hose of the kind mentioned at the outset and this hose is characterized by the fact that the insertion part comprises at least two, running next to each other, preferably in one piece and cast in the form of bands, channels in the outer walls of which micro-openings have been created for passage from the inside out under a on
. forhånd fastlagt indre overtrykk. . predetermined internal excess pressure.
Det innledningsvis nevnte sammenpressbare, porøse materiale er med fordel skumplast men kan være et hvilket som helst materiale som tilfredsstiller kravene, for eksempel fintråd stålull. The initially mentioned compressible, porous material is advantageously foam plastic but can be any material that meets the requirements, for example fine wire steel wool.
Oppfinnelsen skal illustreres nærmere under henvisning til den vedlagte skisse der innføringssdelen (1) i det viste tilfellet omfatter tre ved siden av hverandre forløpende kanaler (2) som hver er utstyrt med mikroåpninger (3) som, på grunn av slangens hvelvede konfigurasjon, under overtrykk i kanalene (2) vil åpne seg for utslipp men som ved undertrykk i kanalene vil tettes. The invention shall be illustrated in more detail with reference to the attached sketch where the introduction part (1) in the case shown comprises three channels (2) running next to each other, each of which is equipped with micro-openings (3) which, due to the hose's vaulted configuration, under overpressure in the channels (2) will open for discharge, but which will close when there is a negative pressure in the channels.
Det pålagte dekke (4), fortrinnsvis av en skumplast med gjennomgående porer, skal sikre ytterligere fordeling av injeksjonsmaterialet samtidig som mikroåpningene søkes holdt fri. The applied cover (4), preferably made of a foam plastic with continuous pores, must ensure further distribution of the injection material while the micro-openings are sought to be kept free.
Produktet ifølge oppfinnelsen er enkelt og lett å fremstille sammenlignet med den kjente teknikks mest sofistikerte utførelsesformer og kan derfor fremstilles til meget lav pris samtidig som den ønskede grad av driftssikkerhet opprett-holdes . The product according to the invention is simple and easy to produce compared to the most sophisticated embodiments of the known technique and can therefore be produced at a very low price while maintaining the desired degree of reliability.
Oppfinnelsens gjenstand tilfredsstiller derfor markedets behov for et rimelig produkt med rimelig sikkerhet til bruk 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 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 block water, then at least to delay water penetration into to such an extent that the protection is in proportion to the present risk.
