Description
Przedmiotem wynalazku jest koncówka do pobierania próbek gruntów o nienasyconej strukturze.The subject of the invention is an attachment for taking samples of soils with unsaturated structure.
Znane i powszechnie stosowane koncówki do pobierania próbek gruntów osadzane na kolumnie zerdzi maja ksztalt cylindrów zaostrzonych w dolnej czesci.Known and commonly used tips for taking soil samples, which are placed on a column of poles, may the shape of the cylinders pointed at the bottom.
Zasadnicza wada tych koncówek jest to, ze w czasie ich wyciagania zbyt czesto próbki gruntu wypadaja z nich ulegajac zniszczeniu. Stosowane dodatkowe urzadzenia w postaci wentyli zwrotnych lub tloków wywolujace nad próbka podcisnienie zapobiegajace wypadaniu ich nie zawsze zdaja egzamin.The main disadvantage of these tips is that when pulling them out, too often soil samples fall out of them undergoing destruction. Additional devices in the form of check valves or pistons are used the pressure over the sample, preventing them from falling out, does not always work.
Sa one klopotliwe w stosowaniu z uwagi na to, ze uzycie tloka wymaga dodatkowej kolumny zerdzi, a zastosowanie wentyla zwrotnego bardzo czesto zawodzi z powodu latwego dostepu do niego ziarn gruntu.They are troublesome to use due to the fact that the use of a piston requires an additional column of rods, and the use of a check valve fails very often due to the easy access of soil grains.
Celem wynalazku jest wyeliminowanie przytoczonych wad i niedogodnosci oraz opracowanie prostej konstrukcji koncówki gwarantujacej pobieranie próbek gruntu o nienaruszonej strukturze.The aim of the invention is to eliminate the cited drawbacks and inconveniences and to provide a simple one the construction of the tip to guarantee the sampling of the soil with an intact structure.
Nieoczekiwanie stwierdzono, ze cel wedlug wynalazku mozna uzyskac wykonujac w znanych koncówkach do pobierania próbek gruntu powyzej zaostrzonego konca wyciecie i wywiniete z niego na zewnatrz ostrze.It has surprisingly been found that the object of the invention can be achieved by using known tips for sampling the ground above the sharpened end of the cut and the blade pulled out of it.
Zastosowanie koncówki wedlug wynalazku umozliwia pobieranie próbek gruntu o nalezytej jakosci i nienaruszonej strukturze, a w konsekwencji zapewnia wlasciwe okreslenie nosnosci podloza budowlanego i mozliwosc oszczedniejszego zaprojektowania budowli.The use of the tip according to the invention allows for taking soil samples of appropriate quality and intact structure, and consequently ensures the correct determination of the bearing capacity of the building substrate and the possibility of more economical building design.
Przedmiot wynalazku jest przedstawiony w przykladzie wykonania na rysunku, na którym fig. 1 przedstawia koncówke do pobierania próbek gruntu w pólwidoku-pólprzekroju, a fig. 2 koncówke w przekroju wzdluz linii A-A.The subject of the invention is shown in the example of the drawing in which Fig. 1 shows the tip for taking soil samples in a half-view-half-section, and Fig. 2 the tip in cross-section along the A-A line.
Koncówka wedlug wynalazku ma ksztalt cylindra majacego w dolnej czesci sciecie stanowiace ostrze 1, a powyzej niego ma wykonane wyciecie 2 i wywiniete z niego na zewnatrz ostrze 3.The tip according to the invention has the shape of a cylinder having a cut in the lower part which constitutes the blade 1, and above it has a cut-out 2 and a blade 3 twisted out of it.
Celem zabezpieczenia wypadnieciu próbki gruntu z cylindra koncówki nalezy po wcisnieciu jej na zadana glebokosc obrócic nia w jedna strone. W wyniku tego nastepuje tarcie gruntu o wewnetrzne sciany cylindra powodujace zageszczenie sie wierzchniej warstwy próbki znajdujacej sie w bezposrednin- sasiedztwie ostrza 3 oraz zaklinowanie sie gruntu w wycieciu 2.9 101 397 JIn order to prevent the soil sample from falling out of the cylinder, the tip should be pressed on the desired one turn it to one side. As a result, the ground rubs against the inner walls of the cylinder causing the surface layer of the sample in the immediate vicinity of the blade to thicken 3 and ground jamming in the cut 2.9 101 397 J.
