Description

Barrel Drill for Soft Sediment Drilling {The barrel type drill for a soft deposit}

The present invention relates to a drilling machine used for the purpose of vertical tissue observation by drilling soft deposits.

Soft sediments are formed mainly by the action of river water, ground water, blue, algae, wind, glaciers, etc., and are soft, so they do not use boring or drills used for drilling rocks to collect samples for vertical tissues. A metal tube is placed on the earth's surface using a vibrator to penetrate the tube into the strata, and the vertical structure is identified through a sample of columnar bodies filled in the tube.

In order to use a conventional soft sediment sampling, the metal tube 11 as shown in FIG. 5 is used. Both sides of the tube extracted after drilling are cut by the grinder 12 to secure an internal sample. As a result, the cost of drilling increases due to the use of one expensive metal tube to obtain a single sample, and if the high level of care is not taken, the sample is disturbed during the cutting of the tube and the preservation of the sample is difficult, and the accuracy of the sample is ensured. In order to grasp a certain number of samples per unit area, a large amount of metal pipes should be used to understand the geological structure of a large area. Therefore, the drilling cost is very high, and a large amount of drilling pipes are transported on the soft ground which is difficult to enter the vehicle. Or had a very difficult problem to handle.

The present invention uses light and inexpensive plastic barrels instead of expensive metal pipes, which are used as consumables in the past, to reduce drilling costs, facilitate transportation and handling, and to grasp the structure of samples collected by using transparent barrels. The barrel-type drilling machine is designed to make the drilling work very easy by immediately making it easy, preserving the secured sample, and continuously drilling by replacing only the barrel which is easy to carry and handle. It is intended for presentation.

To this end, the present invention is coupled to the cylindrical outer tube and the outer tube bottom portion and the bit and the tip bearing the penetration resistance is coupled to the cylindrical barrel of the plastic material and the upper end of the outer tube so as to be caught on the upper surface of the bit By introducing a new barrel drilling device consisting of a cap that secures the barrel in motion, the outer tube, the beet, and the cap are continuously reused, and only the inner barrel is exchanged for sampling.

Figure 1 is an exploded perspective view for showing the basic configuration of the present invention, Figure 2 is a cross-sectional configuration for showing a combined state of the present invention, the present invention is the outer tube (1), the bit (2), barrel (3) And a cap 4.

The outer tube (1) is a cylindrical tube that protects the barrel of the inside. It is made of carbon tube of light and strong material or metal tube, and can be composed of long / short length tube according to drilling depth. The diameter can be freely determined according to the drilling standard.

The top and bottom of the outer tube (1) is formed with a screw groove (10a) for coupling and fixing the cap and the bit to be described later is configured to be coupled by the tightening screw 10, respectively, and stepped inward to the lower end of the outer tube It becomes the structure in which (1a) is formed.

Bit (2) is coupled to the lower end of the outer tube (1) to cut the wear-resistant cylindrical metal tube tip at an oblique angle to form a wedge to reduce the resistance at the time of stratum penetration, stepped (2a) The outer diameter of the bit 2 and the outer diameter of the outer tube are of the same size, but the inner diameter of the bit is smaller than the inner diameter of the outer tube so that the bit and the outer tube are formed to fit. By forming the jaw by the bit at the engaging portion of the barrel is inserted into the outer tube is configured to be caught by the jaw.

Barrel (3) is a cylindrical tube inserted into the outer tube is filled with a hollow sample, using a light plastic material.

When the barrel is made of a transparent plastic tube, there is an advantage that it is possible to grasp the sample structure inside without cutting the barrel, and when cutting to grasp the physical properties of the internal sample, it is very easily cut unlike a conventional metal tube. This can significantly reduce the effort of cutting off.

The outer diameter of the barrel is approximately equal to the inner diameter of the outer tube so that no flow due to voids occurs when it is inserted into the outer tube. To fill the barrel continuously without jamming.

The cap 4 coupled to the upper end of the outer tube is intended to be fixed to the outer tube so that the inner barrel is not pushed out when penetrating into the strata. The upper end is configured to be fixed.

The cap and the bit are fixed to the outer tube by the tightening screw 10, respectively, are coupled to separate each other by loosening the tightening screw is configured to detach the barrel inside.

On the other hand, the present invention can form a barrel extraction groove (6) on the top of the outer tube to facilitate the extraction of the barrel from the outer tube, by doing so a portion of the barrel in the state inserted into the outer tube Exposed through (6), it can be easily extracted with forceps and the like using the exposed area.

Figure 3 is a diagram showing the state of use of the present invention by inserting the barrel cut to the length of the outer tube in a state in which the bit (2) coupled to the outer tube (1) and then combine the drill by the order of fixing with a cap When the bit is applied to the drilling site and the vibrator 7 is used to vibrate and disturb the outer periphery, the drilling machine is gradually introduced into the stratum.

The vibrator 7 is used together with the drilling machine as a device to convert the rotational motion of the prime mover into a vertical strike force to intrude by continuously hitting the drilling machine.

As the drilling machine penetrates into the stratum, the stratum structure is filled into the barrel, and after injecting it up to the depth of irradiation, sealing the upper part of the barrel to apply vacuum tools to the inside to extract the extraction tool (tribal, etc.). Use it to pull out the drill hole.

At this time, the vacuum pressure acting on the barrel by the sealing of the barrel serves to prevent the sample from the barrel during the extraction of the drilling hole.

After extraction, the cap 4 is separated and the barrel is extracted from the outer tube, and the sample 8 is drawn inside the barrel, and when the transparent barrel is used, the inner stratum structure can be immediately confirmed from the outside.

Figure 4 shows the deposition structure of the sample filled in the barrel, it is possible to immediately check the vertical structure of the deposit through the transparent berell.

By this operation, the light and cheap barrels can be replaced by a new one only by replacing them with new ones, and by preparing only the required number of barrels, a desired number of samples can be taken.

The present invention allows the drilling of soft deposits by repeatedly using the outer tube, the bit and the cap and replacing only the barrel with a low price, which can significantly reduce the cost of drilling compared to the conventional, lightweight and transparent plastic material. By using the barrel of the product, not only the handling is easy but also the state of the sample can be checked at the same time as drilling, and the sample is stored in the barrel, or if necessary, the barrel can be easily divided to identify the state of the deposit.
