Description

Guide casing {Guide casing}

The present invention relates to the field of construction, and more particularly to a guide casing used for ground drilling.

Sheet piles are continuously inserted into the ground as shown in FIG. 1 to form the order walls. In order to continuously insert the bent sheet pile into the ground, the ground into which the sheet pile is to be inserted should first be formed.

In the process of continuously inserting the sheet pile, the protective sheet pile 13 to prevent the wing portion 121 of the recently constructed sheet pile 12 from being damaged by the bit of the punching device during the formation of a new drilling hole 102. It is arranged as shown in FIG.

On the other hand, after the new drilling hole 102 is formed, a soft filler such as sand fills the drilling hole 102, and the protective sheet pile 13 is pulled out of the ground. Afterwards, the protective sheet pile 13 is inserted into the drilling hole 102 filled with the filler as shown in FIG. 3.

After that, the new sheet file 14 is again used as a protective sheet file in order to continuously insert the sheet file.

In this conventional sheet pile construction method, the process of inserting and removing the protective sheet pile is continuously performed, and thus the construction period is long. In addition, there was no structure for guiding the sheet pile already constructed, so that the drilling holes could not be continuously constructed in the desired direction. In particular, when the bit of the drilling device reached the rock layer, the drilling hole could not be continuously drilled in the desired direction.

The present invention is to provide a guide casing that allows the through-hole to be drilled while protecting the wing of the already inserted sheet pile without using a protective sheet pile separately.

In addition, it is intended to provide a guide casing that does not need to penetrate a wide range of rock layers by preventing the body portion of the guide casing from reaching the rock layers.

In addition, even if the body portion does not reach the rock layer, it is intended to provide a guide casing to increase the verticality of the newly formed boring hole by guide coupling to the end of the wing portion of the sheet pile already inserted in the auxiliary guide portion.

According to an aspect of the present invention, the hollow body portion is formed so that the bit can be inserted, the first guide portion that can be coupled to the wing portion of the sheet pile already inserted by coupling to the outside of the body portion, and A guide casing is provided that includes an extension portion coupled in the longitudinal direction of the body portion at a position of a first guide portion, and a second guide portion continuously coupled to the first guide portion and formed outside the extension portion.

In addition, the first guide portion may include a pair of protrusions.

In addition, the length of the body portion may be shorter than the length of the sheet pile.

As described above, by using the hollow body portion shorter than the length of the sheet pile can not be inserted into the rock layer. This can reduce the time and cost of expansion of the rock bed.

In addition, the extension portion coupled to only a portion of the body portion and the second guide portion coupled to the outside of the extension portion can be combined with the entire wing portion of the sheet pile guide. As a result, it is possible to continuously form a high vertical hole.

DETAILED DESCRIPTION Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are intended to explain in detail enough to enable those skilled in the art to easily carry out the present invention. This does not mean that the spirit and scope of the present invention is limited.

4 is a perspective view of a guide casing according to an embodiment of the present invention, Figures 5 to 7 is a process chart showing a process of continuously inserting a sheet pile into the ground using the guide casing according to an embodiment of the present invention. .

The guide casing 20 of the present embodiment may be coupled to the wing and the wing of the sheet pile already inserted by coupling to the body portion 21 of the hollow body formed so that the bit can be inserted, the body portion 21 The first guide part 231, the extension part 22 coupled in the longitudinal direction of the body part 21 at the position of the first guide part 231, and the first guide part 231 continuously. It includes a second guide portion 232 coupled to the outside of the extension portion 22.

The body portion 21 is penetrated so that the bit can be inserted. Body portion 21 is generally used in the form of a circular pipe. The body portion 21 may be a metallic pipe.

The outer side of the body portion 21 is formed with a first guide portion 231 in the longitudinal direction of the body portion 21. The first guide portion 231 may be coupled in the longitudinal direction to the body portion 21 in a pair of protruding form. The shape of the first guide part 231 can be modified in various forms as long as it can be combined with the wing portion 1111 of the seat pile 111 as shown in FIG.

Extension portion 22 is coupled to only a portion of the body portion 21 extends in the longitudinal direction of the body portion 21. The position of the extension part 22 is a part where the first guide part 231 is located. Extension portion 22 may be welded to the body portion 21, it may be integrally coupled as a casting.

The second guide part 232 is coupled to the outside of the extension part 22. The second guide part 232 is formed continuously with the first guide part 231. As illustrated in FIG. 4, the first guide portion 231 is coupled to the region a belonging to the body portion 21, and the second guide portion 232 is coupled to the region b belonging to the extension portion 22.

As for the guide casing 20 of this embodiment, the length of the body part 21 extends only to the position in which the 1st guide part 231 was formed like FIG. The combined length of the first guide part 231 and the second guide part 232 is similar to the length of the sheet pile 111.

As such, the reason for shortening the length of the body portion 21 is to prevent the body portion 21 from being inserted to the depth where the rock layer of the ground is located. To drill the ground, the bit rotates. Insert the guide casing 20 into the drilled hole by the rotation of the bit. At this time, in order to insert the body portion 21 of the guide casing 20, a hole having a shape larger than that of the body portion 21 should be formed. In the case of soil layer, it is easy to form a large hole, but in the case of a rock layer, the process time is long when a hole having a large diameter is formed.

Therefore, the length of the body portion 21 of the present embodiment is shorter than the length of the sheet pile so that the body portion 21 does not reach the rock layer. On the other hand, the rock layer is formed with only a minimum hole, the extension portion 22 is inserted into the hole, the second guide portion 232 coupled to the outside of the extension portion 22 to the end of the sheet pile 111 Guides combine.

As such, the length of the body portion 21 is shorter than the length of the sheet pile, thereby reducing the burden of forming a large perforation hole in the rock layer. In addition, the second guide part 232 guides the wing part 1111 of the sheet pile 111 to form a continuous hole having a high vertical degree.

The method of continuously constructing the sheet pile using the guide casing 20 of this embodiment can be described with reference to FIGS. 5 to 7.

5 is a cross-sectional view showing a construction method of a sheet pile. To form a punching hole 110 next to the sheet pile 111 is already inserted. First, in the state in which the wing portion 1111 and the second guide portion 232 of the sheet pile 111 are guide-coupled, a bit is inserted into the body portion 21 to form a punching hole 110.

FIG. 6 shows a cross-sectional view of forming the drilled hole 300 by using the guide casing 20 in the ground. In the ground, a soil layer is formed on the surface layer, and a rock layer is formed on the deep layer. It can be seen that the body portion of the guide casing 20 does not reach the rock layer. However, the drilling hole 300 may be formed to the depth where the sheet pile 111 is constructed by the second guide part formed in the extension part.

When the punching hole 110 as shown in FIG. 5 is formed, a filler such as sand is filled into the punching hole 110. Thereafter, the guide casing 20 is pulled out from the ground. Thereafter, a new sheet file 112 is inserted as shown in FIG. 7. On the other hand, the guide casing 20 may form a new drilling hole 120 again while guiding the new sheet pile 112. In this way, it is possible to form successively high vertical drilling holes, and the sheet pile is continuously connected to the drilling holes.

Since the above has been described only with respect to some of the preferred embodiments that can be implemented by the present invention, the scope of the present invention, as is well known, should not be construed as limited to the above embodiments, the present invention described above It will be said that both the technical idea and the technical idea which together with the base are included in the scope of the present invention.
