Description
Anordning for opptagning av jordprøver. Device for recording soil samples.
Foreliggende oppfinnelse går ut på en anordning for opptagning av prøver fra de løse jordlag, og fra de fjellarter i hvilke prøvetagningsanordninger kan neddrives. Anordningen har interesse for den geolog-iske vitenskap, men turde være mest an-vendelig innen geoteknikken. The present invention concerns a device for collecting samples from the loose soil layers, and from the rock types in which sampling devices can be driven down. The device is of interest to geological science, but should be most applicable in geotechnics.
Det er kjent forskjellige anordninger for opptagning av jordprøver omfattende et prøverør, anordnet inne i et omgivende rør, som er bestemt til å slåes ned i jorden. Det er herunder kjent å forsyne prøverøret med utadrettede fliker ved den nedre åpne ende, hvilke fliker, etter at prøverøret er fylt med jord er bestemt til å ombøyes innover, for å hindre jordprøven i å gli ut av røret, når dette trekkes opp. Different devices are known for collecting soil samples comprising a sample tube, arranged inside a surrounding tube, which is intended to be driven into the ground. It is known below to provide the test tube with outward-facing tabs at the lower open end, which tabs, after the test tube is filled with soil, are intended to bend inwards, to prevent the soil sample from sliding out of the tube when it is pulled up.
Til forskjell fra denne kjente anordning er prøverøret ifølge oppfinnelsen forsynt med rette fliker, som forløper i rørets lengderetning. Anordningen er videre ut-ført slik at disse fliker, etter at prøverøret er fylt med jord, kan bøyes inn på en slik måte at jordprøven ikke skades eller defor-meres. In contrast to this known device, the test tube according to the invention is provided with straight tabs, which extend in the longitudinal direction of the tube. The device is also designed so that these tabs, after the test tube is filled with soil, can be bent in such a way that the soil sample is not damaged or deformed.
Anordningen ifølge oppfinnelsen har først og fremst til formål å ta opp en i det vesentligste vertikal jordsøyle med relativt stor diameter, i hvilken jord- og fjellarte-nes sjiktdannelse fremdeles kan iakttas, hvorunder de løse jordarter i prøven skal beskyttes mot utskylling under prøvetag-ningens gang, nemlig når prøvetagningen foregår under vann eller grunnvann, og prøven effektivt skal forbli i prøvetag-ningsrøret. Da anordningen er bestemt for The device according to the invention primarily aims to take up an essentially vertical column of soil with a relatively large diameter, in which the stratification of the soil and rock types can still be observed, under which the loose soil types in the sample must be protected against washing out during the sampling time, namely when the sampling takes place under water or groundwater, and the sample must effectively remain in the sampling tube. As the device is intended for
anvendelse i relativt stor dybde, er dét lagt stor vekt på at alle ømfintlige deler, som er nødvendige for anordningens funk-sjon, er anbragt over jorden. application at relatively great depth, great emphasis is placed on ensuring that all sensitive parts, which are necessary for the device's function, are placed above ground.
På vedlagte tegning er som eksempel vist en utførelsesform av anordningen iføl-ge oppfinnelsen. På tegningen viser fig. 1 prøvetagningsrøret åpent under neddriv-ing i jorden, og fig. 2 viser prøvetagnings-røret lukket etterat prøven er ferdig tatt. The attached drawing shows, as an example, an embodiment of the device according to the invention. In the drawing, fig. 1 the sampling tube open during driving down into the earth, and fig. 2 shows the sampling tube closed after the sample has been taken.
Som vist på fig. 1 er et prøvetagnings-redskap 1 festet på et kraftig rør 2, som kan være påskjøtt til en relativt stor leng-de. Oventil er dette rør forbundet med et slaghode 3, på hvilket et slagstykke 4 er anbragt. På dette slagstykke kan senere en vanlig rambukk utføre sitt arbeide og ned-drive helt anordningen i jorden. I slaghodet 3 er det anordnet en innvendig fals 5, på begge sider av hvilken det er anbragt be-festigelsesmuffer 6 og 7 på prøvetagnings-røret 8, og holder dette ubevegelig i sin stilling i forhold til det ytre beskyttelses-rør 2 og prøvetagningsredskapet 1. Den nedre ende av prøvetagningsrøret er forsynt med flikeV 10, som er slik anordnet at de kan bøyes innover, og derunder lukke prøvetagningsrøret. Prøvetagningsredska-pet 1 er på innsiden forsynt med et nedover avsmalnende parti 9, som kan ha form f. eks. av en sfærisk eller konisk flate, eller skråtstilte plane flater. Platen 9 er utfor-met slik at flikene 10 i den nedre ende av prøvetagningsrøret 8 tvinges til å bøye seg innover mot hverandre, og danne en halv-sfærisk eller lignende flate, når røret 8, se fig. 2, drives nedover i forhold til prøvetag-ningsredskapet 1 ved hjelp av den ram-bukkanordning som er anvendt for å slå hele anordningen ned i jorden. Herved vil den prøve som har trengt inn i prøvetag-ningsrøret effektivt holdes i sin stilling, og beskyttes når det tas opp gjennom røret 2. Når prøven, som er helt innesluttet i prøve-tagningsrøret 8, er tatt opp til jordoverflaten, kan den lett tas ut, enten ved å sage av de sammenbøyde fliker 10 eller ved at røret 8 sages av i lengden. Alternativt kan prøvetagningsrøret 8 være forsynt med en løsbar flikring, som ved hjelp av gjenger eller lignende er anbragt på den nedre ende av røret. Den nedre del av prøvetagnings-røret som er forsynt med fliker, bør således være utført av et ved store deformasjoner plastisk materiale. As shown in fig. 1 is a sampling tool 1 attached to a strong tube 2, which can be used for a relatively large length. Above, this pipe is connected to an impact head 3, on which an impact piece 4 is placed. On this impact piece, a regular ram can later carry out its work and completely drive the device into the ground. In the impact head 3, an internal seam 5 is arranged, on both sides of which fastening sleeves 6 and 7 are placed on the sampling tube 8, and holds this immobile in its position in relation to the outer protection tube 2 and the sampling tool 1 The lower end of the sampling tube is provided with tabs V 10, which are arranged in such a way that they can be bent inwards and close the sampling tube below. The sampling tool 1 is provided on the inside with a downwardly tapering part 9, which can have the shape e.g. of a spherical or conical surface, or inclined plane surfaces. The plate 9 is designed so that the tabs 10 at the lower end of the sampling tube 8 are forced to bend inwards towards each other, and form a hemispherical or similar surface, when the tube 8, see fig. 2, is driven downwards in relation to the sampling tool 1 by means of the ram-bending device which is used to drive the entire device into the ground. In this way, the sample that has penetrated the sampling tube will be effectively held in its position, and protected when it is taken up through the tube 2. When the sample, which is completely enclosed in the sampling tube 8, has been taken up to the earth's surface, it can easily is taken out, either by sawing off the bent tabs 10 or by sawing the tube 8 lengthwise. Alternatively, the sampling tube 8 can be provided with a detachable flap ring, which is placed on the lower end of the tube by means of threads or the like. The lower part of the sampling tube, which is provided with tabs, should therefore be made of a plastic material in case of large deformations.
For å unngå en altfor stor vannsøyle ovenfor prøven, er prøvetagningsrøret 8 forsynt med utløpshull 12 for vann omtrent ved den øverste kant av prøven. Herved kan vannet inne i prøvetagningsrøret ren-ne ut i beskyttelsesrøret 3, når prøvetag-ningsrøret langsomt trekkes opp gjennom dette beskyttelsesrør. Vannoverflaten inne i beskyttelsesrøret 2 bør under hele prøve-tagningsforløpet holdes i samme nivå som vannoverflaten utenfor røret, hvilket lett kan skje ved påfylling av vann ovenfra. Ved denne fremgangsmåte umuliggjøres vannføring gjennom hullet i prøvetag-ningsredskapet 1, og dermed elimineres den vanlige årsak til utskylling av fine partik-ler fra prøven. Stillingen av prøveoverfla-ten kan lett kontrolleres ved at man fører ned en stang eller et lodd gjennom prøve-tagningsrøret. In order to avoid an overly large column of water above the sample, the sampling tube 8 is provided with an outlet hole 12 for water approximately at the top edge of the sample. This allows the water inside the sampling tube to drain into the protective tube 3, when the sampling tube is slowly pulled up through this protective tube. The water surface inside the protective tube 2 should be kept at the same level as the water surface outside the tube during the entire sampling process, which can easily happen when filling with water from above. With this method, the flow of water through the hole in the sampling tool 1 is made impossible, and thus the usual cause of fine particles being rinsed out of the sample is eliminated. The position of the sample surface can be easily checked by passing a rod or a plumb bob through the sampling tube.
