Description
Bodenprüfvorrichtung Die bekannten Bodenprüfapparate zur Feststellung des Tragvermögens von Bodengattungen, bei denen mit Hilfe des Stempels einer hydraulischen Presse ein meßbarer Druck auf einen -''bestimmten Oberflächenteil des zu untersuchenden Bodens ausgeübt wird, haben den Nachteil, daß sie entweder ein festes Widerlager benötigen oder mit Hilfe von Gewichten oder besonderen Einrichtungen niedergedrückt werden müssen, was oft mit bedeutenden Transportkosten verbunden bzw. bei beschränkten Raumverhältnissen oder unebenem Terrain überhaupt nicht möglich ist.Soil testing device The known soil testing devices for detection the load-bearing capacity of types of soil where, with the help of the ram, a hydraulic Put a measurable pressure on a - '' certain part of the surface of the object to be examined Soil is exercised, have the disadvantage that they are either a fixed abutment need or depressed with the help of weights or special devices must be, which is often associated with significant transport costs or limited Spatial conditions or uneven terrain is not possible at all.
Die Erfindung bezweckt die Behebung dieses Mangels, was dadurch erreicht werden kann, daß als Widerlager eine mittels Zuganker verankerte Spannsäule dient, wobei die Zuganker in an sich bekannter Weise an in die Erde getriebenen Haftpflöcken befestigt sind.The invention aims to remedy this deficiency, which is achieved thereby it can be that a tensioning column anchored by means of tie rods serves as an abutment, the tie rods in a manner known per se on adhesive pegs driven into the ground are attached.
In den A !bb. i und 2 ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsform veranschaulicht, und zwar zeigt Abb: i eine Seitenansicht und Abb. 2 den Grundriß dazu.In the A! Bb. i and 2 is the subject matter of the invention in an exemplary manner Embodiment illustrated, namely Fig: i shows a side view and Fig. 2 the floor plan for it.
Auf eälem Druckstempel D, dessen Basis mit quadratischer oder runder Fläche auf die zu prüfende Bodenstelle drückt, sitzt eine hydraulische Presse H, der durch einen biegsameji Schlauch B von einer Pumpe P die Druckflüssigkeit zugeführt werden kann. Ein Manometer M ermöglicht die Ablesung des Drqckes in der Pumpe, der mit Hilfe eines Reduzicrventils V auf beliebige Zwischenstufen eingestellt werden kann. Da die Flächen des Preßkolbens und des Druckstempels so-,vie der Flüssigkeitsdruck bekannt sind, läßt sich die Pressung auf den Boden berechnen. Zur Bestimmung der Einpressung des Druckstempels D dient eine getrennt vom Apparat aufgestellte Ablesevorrichtung A. Als Widerlager für die Presse H dient eine Spannsäule S, deren oberes Ende mittels Zuganker Z, welche mit Spannschlössern nachspannbar sein können, mit in die Erde getriebenen Haftpflöcken K verbunden ist. Der Hauptvorteil der Einrichtung besteht in dem geringen Raumbedarf, wobei noch ganz besonders der Vorteil zustatten kommt, daß bei der Untersuchung einer benachbarten Bodenstellebloß ein Haftpflock herausgezogen und an einer anderen Stelle eingetrieben werden muß. In der Regel kommen drei Zuganker in Anwendung; doch kann deren Anzahl je nach Bedarf auch eine andere sein.On one stamp D, the base of which is square or round Presses the surface onto the area to be tested, a hydraulic press H is installed, which is supplied by a flexible hose B from a pump P with the pressure fluid can be. A manometer M enables the pressure in the pump to be read off can be set to any intermediate stage with the aid of a reducing valve V. can. Since the surfaces of the plunger and the pressure ram as well as the fluid pressure are known, the pressure on the ground can be calculated. To determine the A reading device set up separately from the apparatus is used to press in the plunger D A. A clamping column S is used as an abutment for the press H, the upper end of which is by means of Tie rods Z, which can be retightened with turnbuckles, also in the ground driven adhesive pegs K is connected. The main advantage of the establishment is in the small space requirement, whereby the advantage is particularly useful, that when examining a neighboring ground, only an adhesive stake was pulled out and must be driven in at another point. There are usually three tie rods in use; however, their number can also be different as required.
