DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a perforation device equipped with a rotary perforator and a percussion type perforator.

Poling work occupies an important position in various civil engineering works such as anchor work, slope work, and grouting work. In addition to rotary drilling machines that drill holes using only rotational force and pressing force, percussion drilling machines that drill holes by applying rotational force and pressing force while applying impact force to the rod using air etc. Boring machines are known.

In the case of the former rotary type, although it is possible to drill large diameter holes, it has the disadvantage that the drilling speed is somewhat slow. In the case of the latter percussion type, although it can only drill holes with a diameter of about 137 mm or less, it also has the advantage of being able to drill holes at a high speed because it also applies impact force. However, even in the case of the R-cution method, when drilling to a long depth, especially around 40
When attempting to drill a hole of 40 m or more, frictional resistance from the surrounding ground is applied to the drilling rod, especially in the case of collapsible ground, and the drilling speed sharply decreases when the hole exceeds 40 m.

For these reasons, conventionally it has been usual to select the type of drilling machine according to the properties of the target ground. Drilling efficiency may be extremely poor if you use it all the time. For this reason, a method has been adopted in which a variety of drilling machines are sequentially used to perform step-drilling, but this method has disadvantages such as being very time-consuming to install the machines and making it difficult to get the center out.

When drilling holes, usually, first, the truck 1 is set in a predetermined position, and then the iL hole is adjusted by adjusting the rising angle of the platform 4.
An outer tube Ou having a bit B1 at the tip is brought in, and a rotary drilling machine 12 is used to drill a hole through the outer tube Ou while adding holes sequentially as the hole is drilled. After drilling to a suitable depth, bring in the inner tube In with bit B2,
The inner pipe In is bored through the outer pipe O to a predetermined depth by the percussion type drilling machine 19, with holes being added sequentially as the holes are drilled.

According to such a drilling mode, after drilling is performed in advance by the rotary drilling machine 12, a slight force is applied to the drilling machine 19.
Since the outer pipe Ou functions as a casing for the inner pipe In, even if a restraining force is applied from the topsoil part and the clay or gravel part beyond it, there is no contact restraining force on the inner pipe In. Therefore, there is no reduction in the drilling speed of the percussion type drilling machine 19, and it is possible to smoothly drill deeper rock sections, and it is extremely easy to drill long holes. Furthermore, since the central axis position of the inner tube In is regulated by the outer tube O as a casing, bending of the hole is suitably prevented. Especially as shown,
If the direction of rotation is reversed, with the outer tube Ou (clockwise) and the inner tube In counterclockwise, the rotational torques cancel each other out and become uniform with respect to the central axis, which is even more effective in preventing hole bending.

On the other hand, the order of drilling is not limited to the above example, and the drilling by the inner tube I may be performed first. In this case, since the guide hole is formed by drilling through the inner pipe IP, it is easy to make the hole through the outer pipe Qu. Furthermore, depending on the layer condition of the ground or the presence or absence of obstacles in the ground (for example, reinforcing bars buried in previous construction work), the rotary drilling machine 12 may be used to drill the outer pipe. u in advance or the inner tube Ir by the percussion type perforator 19! It is possible to perform drilling while appropriately selecting whether to precede the drilling.

By the way, the pressing forces of the rotary punching machine 12 and the gusset punching machine 19 are controlled by the feed motors 16 and 19, respectively.
23 alone is insufficient, the pressing force can be supplemented by activating the cylinder 7 and moving the main base 8 forward. Although a specific example is not shown in the drawing, a thrust replenishment cylinder is provided on the main base 8, and its rod is connected to the auxiliary base 11, and the auxiliary base 11 is moved forward and backward along the main base 8. If it is possible to advance, it can be replenished separately from the press force replenishment using the force-solution type drilling, which is an extremely suitable mode for operation. In the case of long holes, if the impact force applied to the base of the inner tube is absorbed midway and the impact force is not sufficiently transmitted to the tip ridge, a well-known down-the-hole hole may be applied to the tip of the inner tube.・It is also possible to set up a server.

On the other hand, in the above example, as shown in Fig. 3, the outer tube O is rotary, the inner tube In is a single tube, and this single tube is rotated while giving percussion by a top hammer or a down-the-hole hammer. It is meant to give you strength. On the other hand, as shown in FIG. 4, the inner tube In is
It has a double tube structure in which the middle tube InA and the inner tube InB move integrally, the middle tube IqA is a rotary type, and the inner tube IpB is a R-cussion type with a down-the-hole hammer/mer and is rotated. You can do it like this. Furthermore, as shown in Fig. 5, the inner tube has a double tube structure, and the middle tube InA is configured to provide percussion and rotational force using one top hammer type, and the inner tube InB is configured to use a single top hammer type to provide percussion and rotational force. ? - It is also possible to apply a sharp rotational force.
