Definitions
- the present invention relates to a penetrometer or device for recognizing the subsoil intended in particular, but not exclusively, for the recognition of the seabed, over a depth of up to a few tens of meters.
- CPT static penetrometer test
- This test consists in pushing into the affected areas a rod fitted at its lower end with sensors making it possible to continuously measure certain parameters such as peak resistance and lateral friction while driving.
- the rod cylindrical
- Penetration takes place at a continuous speed of 2 cm / sec; the depth of investigation and therefore the length of the rod varies, depending on the case, from a few meters to a few tens of meters.
- the pushing force on the rod which depends on the resistance of the terrain and the depth of the investigation, commonly varies from a few tonnes to 20 tonnes, a value beyond which the test is normally stopped.
- the thrust is generally exerted by means of a jack pressing on the upper end of the rod.
- the rod consists of elements successively fitted together by screwing.
- the length of each element does not d not exceed a few meters for practical reasons of jacking length and buckling behavior under the thrust force. Penetration takes place step by step, each step corresponding to the length of an element pushed by the jack.
- the object of the present invention is to overcome these drawbacks and to allow CPT tests which can reach penetrations of several tens of meters to be carried out, with equipment of reduced bulk, of an automatic implementation which does not require, in progress. test, manual intervention.
- the underground recognition device comprising a tower, nestable rods and a means for applying pressure to the upper end of the upper rod of the drill string
- the rods are articulated one on the other and arranged on a reel, the reel having a square core whose side is equal to the length of a rod, the reel being carried by a bracket secured to a vertically movable slide in fixed guides, the tower carrying, near its middle part, a pair of claws or retractable pliers cooperating successively with one of the angles of the square constituting the drum.
- the drill string is a continuous train, the rods being hinged together.
- the train does not become rigid until the successive alignment of the rods.
- the rods rest on the reel side by side.
- the pressure is always applied in the axis which avoids buckling and, on the other hand, guides are provided at the lower part of the tower.
- the operation is as follows: After fixing the tool on one end of the first rod, the latter is vertical.
- the pliers are retracted, the jack lowers the reel and the first rod is pressed with the tool, pushed by the second rod into the ground with a length equal to that of a rod. Operations continue until the desired depth has been reached.
- the tool is raised in the opposite direction, the pliers then blocking an angle at the bottom of the drum to prevent it from going down, which forces it to turn in the dextrorsum direction.
- the rods are thus placed, one against the other, on the reel as they are raised. It will be noted that no significant force is exerted on the axis of the reel which only has to support the weight of the reel and the weight of the rods which are wound there. The action of the actuator is exerted only on the rods and at the end thereof.
- the motivity results from the action of a pinion driven by a motor (not shown) on a rack sliding on the tower.
- a slide integral with the rod of one or more cylinders This slide must have a stroke equal to twice the length of a rod. It is he who applies the pressure necessary to penetrate the tool into the basement.
- the device consists of a frame resting on the ground which may be an underwater ground.
- the frame comprises a vertical tower 10 which is of relatively low height compared to that of the known devices since it is of a height substantially equal to twice the length of a rod is a maximum of six meters.
- a bracket 3 which, by means of two arms 2 (only one of which appears in FIG. 1) supports a reel 1.
- the arms 2 are articulated at the end of the bracket 3.
- the reel 1, comprising a core 1a with a square section, is pivotally mounted on one (or two) axis 4 journalled at the lower end of the arms 2 themselves pivotally mounted on the bracket 3.
- the reel 1 In the position shown in the in FIG. 1, the reel 1 is supported by one of its faces against a face of the frame 10. This is the case each time the pressure is applied to a rod 7.
- the drum 1 receives on its core the a plurality of rods 7, articulated at 13 one after the other, which are, in a way, wound side by side on the core the drum 1. They will be unwound and rewound by rotation of the drum 1 around its axis 4.
- a pinion 8 meshing with a rack 9, forming a slide, the rotation of the pinion 8 in one direction or in the other causing the ascent or descent of the rack 9 at the upper end of which is fixed the bracket 3.
- the rack is slidably mounted in vertical guides (not shown) from the tower or gantry. That is to say that the rotation of the pinion 8 causes the stem to rise or fall 3.
- the reel 1 carries in each of these angles protruding pins or pins forming pivots 6 when they are in contact with a clamp 15. These pivots will successively cooperate with the clamp or fork 15 integral with the rod of a jack 5.
- the fork 15 can come in a first projecting position with one of the nipples 6 to block the ascent or descent of the drum 1 and cause it to pivot about the axis 4, while it is inoperative in the second retracted position.
- the reel 1 has four pins on each side and two jacks 5 on either side of the reel as shown in FIG. 2.
- Figure 3 shows the device in the high position. That is to say that under the action of the pinion 8, the bracket 3 has reached its upper position.
- the claw 15 remains in the retracted position and the vertical rod, which is still inside the reel, presses on the immediately lower rod to transmit the penetration force resulting therefrom.
- the clamp 15 comes around the stud 6 located at the lower part of the reel, on the side of the tower, which blocks the descent of said reel. The latter then rotates by an angle of 90 ° in the dextrorsum direction, around the stud 6, so that the corresponding rod 7 is deposited on the reel.
- FIGS. 4A to 4D Figures 4 are simplified diagrams on which we find only the frame 10, the drum 1, the bracket 3 and its articulated arm.
- the reel In FIG. 4A, the reel is in its upper maximum position as shown in FIG. 3. The four angles on one side of the reel 1 are symbolized by the letters A, B, C, D.
- FIG. 4B the reel is lowered, as explained above, under the action of a rack or a jack and it occupies its lower maximum position. It has moved, by a value equal to the length of a rod, in vertical translation, along the tower and we find the same arrangement of the angles as in FIG. 4A.
- the jack 5 brings the clamp 15 around the stud or stud 6 of one angle A which immobilizes it in height.
- the reel is in the position of FIG. 4D and the rod of the jack 5 as well as the clamp 15 is retracted.
- the reel has turned a quarter of a turn which corresponds to the descent of a rod.
- Figures 5A to 5D are diagrams illustrating the ascent of a drill string.
- FIG. 5A the reel is in its lower maximum position.
- the clamp 15 is retracted.
- the bracket 3 and the drum 1 are translated vertically into the position shown in FIG. 5B.
- This translation results in the extraction of the ground from a rod 7.
- the clamp 15 is then advanced and blocks the angle B of the reel as explained above.
- the bracket then descends, but the reel 1 is immobilized in translation around the clamp 15.
- the reel rotates around the angle B in the dextrorsum direction, the arm 2 taking a slight movement.
- the stem 3 took its lowest position, the reel turned a quarter of a turn and one of the rods of the train wound on the reel.
- the angle B is released by removing the clamp 15 and a new cycle can start again.
- Rod articulation systems which can be locked automatically in a determined position and unlocked as soon as the pressure ceases to be applied, in particular by inserting tenons in slots or mortises are known and do not require any particular description.
- the present invention thus makes it possible to have a simple continuous operation penetrometer.
- the simplicity of this allows it to be placed on a seabed that is difficult to access and remote-controlled operation at great depth since cables can deliver the necessary energy from the surface and transmit the captured data back.
- the foregoing description relates to a device for recognizing the subsoil. But it is, of course, possible to use it to serve other equipment with pressed rods, for example, to introduce a measuring tube or cable into the bottom of a pre-existing borehole.
