Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a permeation pipe composed of a concrete pipe, a fume pipe, a vinyl chloride vibrator, etc., in which a plurality of permeation holes are provided at predetermined positions on the pipe wall, and This invention relates to a propulsion burying method in which this percolation pipe is buried underground using a propulsion method.

<Prior art> Conventional infiltration tubes include those disclosed in Japanese Patent Publication No. 13653/1980, Publication No. 19494/1983, and Publication of Japanese Utility Model Publication No. 19936/1973.
A permeation tube having a structure as shown in Japanese Utility Model Publication No. 52-76608 is known.

These techniques involve drilling multiple permeation holes in the wall of a cylindrical pipe such as a humid pipe, or installing a mesh around the permeation holes to prevent them from clogging.
Alternatively, the structure is such that the filter is removably attached to the infiltration hole.

<Problems to be Solved by the Invention> However, since the above-mentioned conventional infiltration pipes are based on the premise of burying the pipes underground by the cut-and-cut method, it is difficult to bury the seepage pipes in places where it is difficult to bury the pipes by the cut-and-cut method. Alternatively, if a percolation pipe is to be constructed at a very deep location underground, it must be buried underground using a propulsion method. Furthermore, in conventional seepage pipes, depending on the type of propulsion method (for example, muddy water method), muddy water may surround the pipe and flow into the pipe through the seepage holes. Therefore, there is a problem in that the conventional permeation tube described above cannot be used as is.

This is because multiple large seepage holes are drilled in the pipe wall, so if you try to bury it underground using the propulsion method, a large amount of earth and sand and muddy water will flow into the pipe from the seepage holes. Alternatively, part of the earth and sand around the infiltration pipe during propagation rubs against the wall of the infiltration hole, making construction difficult.

In addition, it is easy to think of a method of filling the permeation holes of the conventional permeation pipe with rubber material or plastic material and constructing this permeation pipe using the permeation method, but when performing permeation construction, the outer peripheral wall of the permeation pipe Since the pressure applied to the permeation hole is extremely large, even if the permeation hole is simply filled with this kind of material, there is a problem that the filling material easily falls out of the permeation hole due to external pressure, making it impossible to carry out propelling construction.

The permeation tube according to the present invention relates to a completely new technology developed in view of these conventional problems.

Means for Solving the Problems> The present invention is a completely new technology that fundamentally improves the above-mentioned conventional problems. In a pipe, a plug having an outer diameter approximately equal to the inner diameter of the permeation hole is inserted into the permeation hole, and the plug is removably attached and fixed to the pipe wall via a bolt. be.

Further, the method for promoting and burying a permeation pipe according to the present invention involves inserting plugs into each of the plurality of permeation holes of the permeation pipe, and attaching the plugs to the pipe wall via bolts in a detachable manner. A layer of mortar is laminated on the outer surface until it is flush with the outer peripheral surface of the pipe wall to completely cover the seepage hole.Then, the seepage pipe is buried underground using the propulsion method, and the plug body and mortar layer are placed on the wall of the seepage pipe. It is characterized in that it is removed from the inside through a permeation hole, and furthermore, a permeation filter is attached and fixed to the permeation hole.

Function> The infiltration pipe according to the present invention is constructed as described above (a plug body having an outer diameter approximately equal to the inner diameter of the infiltration hole is installed inside the infiltration hole, so this infiltration pipe can be inserted into the ground by the propulsion burying method). Even if buried deeply, sand and mud may flow in through the seepage holes during propulsion.
Alternatively, part of the earth and sand around the infiltration pipe being propelled does not cause friction with the wall surface of the infiltration hole, so that the infiltration pipe can be smoothly propelled.

Furthermore, in the permeation pipe according to the present invention, the plug body is removably attached and fixed to the pipe wall via bolts, so after the permeation pipe is propelled and constructed, the plug body is inserted through the permeation hole in the permeation pipe. It can be removed and a permeation filter can be installed in this permeation hole.

As described above, the penetration pipe propulsion burying method according to the present invention involves removably attaching the plug to the penetration hole via bolts, and applying a predetermined curvature to the outer surface of the plug until it becomes flat with the outer peripheral surface of the pipe wall. After completely shielding the permeation hole by laminating a layer of mortar with a surface, the permeation pipe is buried underground using the propulsion method, completely preventing muddy water from entering the permeation pipe from the permeation hole. Furthermore, the frictional resistance caused by the uneven surface can be eliminated, making the penetration pipe extremely smooth.

Furthermore, in the present invention, the plug body and the mortar layer are removed from the inside of the permeation tube, and the permeation filter is attached and fixed to the permeation hole, so the work is extremely easy. It is possible to stably attach the plug to the penetration hole using an anchor bolt or the like that can fix the plug.

<Example> To specifically describe an example of the infiltration pipe according to the present invention or the method of burying the infiltration pipe by the propulsion method with reference to the drawings, the first embodiment
The figure is an explanatory cross-sectional view showing the main parts of the present invention, Figure 2 is a joint cross-sectional view of the permeation tube, Figure 3 is a cross-sectional view thereof, Figure 4 is a perspective view of the stopper, and Figure 5 is a view of the permeation hole. FIG. 6 is a perspective view of the penetrating filter frame attached, and FIG. 6 is a sectional view of the penetrating filter attached.

In the figure, reference numeral 1 indicates a permeation tube composed of a hume tube, and as shown in FIGS. 2 and 3, a plurality of permeation holes 2 having a predetermined inner diameter are arranged in parallel on the wall of this tube. It is perforated. Next, reference numeral 3 denotes a plug that can be inserted into the penetration hole 2, and is configured to have an outer diameter approximately equal to the inner diameter of the penetration hole 2. This plug body 3 is constructed by pouring concrete 5 inside a metal ring frame 4 and integrating it. Further, a pair of protrusions 6 having bolt holes at corresponding positions are protruded from the upper edge of the ring frame 4.

When attaching the plug 3 having the above-mentioned structure to the penetration hole 2, as shown in FIG.
After insertion, the plug body 3 can be removably attached by attaching the protrusion 6 to the anchor bolt 7 previously embedded in the wall surface of the penetration hole 2 via another bolt 8.

As mentioned above, a mortar layer 9 is laminated on the outer surface of the plug 3 attached to the penetration hole 2, as shown in FIG.
The infiltration tube of the present invention can be constructed by flattening the recess and finishing the surface with the same curvature as the outer peripheral surface of the infiltration tube I.

Next, when burying the infiltration pipe, it is buried deep into the ground using the infiltration pipe configured as described above and a propulsion method (not shown). After the penetration pipe is completely buried, the bolt 8 is removed from the anchor port 7, and the plug body 3 is inserted into the penetration hole 2.
The mortar layer 9 provided on the outside of the stopper 3 is broken and also removed. In this state, the permeation filter frame 10 is inserted into the permeation hole 2 as shown in the fifth section, and the permeation filter frame 10 is attached and fixed by the anchor ports 7 and bolts 8, and further as shown in FIG. As shown, the osmotic filter 11 can be installed within the osmotic filter frame 10 to complete the osmotic conduit.

In the above embodiment, the plug body 3 was constructed by pouring concrete 5 inside the ring frame 4, but the plug body 3 can also be constructed by integrally molding it with casting or the like.

Further, in the above embodiment, a mortar layer 9 is laminated on the outside of the plug 3 installed in the penetration hole 2, thereby making the recess flat and keeping the part of the penetration hole 2 close to the other pipe wall. The mortar layer 9 can be omitted if the outer surface of the stopper 3 is made to have the same curvature as the outer circumferential surface of the tube wall.

<Effects of the Invention> Since the infiltration pipe and the infiltration pipe propulsion method according to the present invention have the structure and operation as described above, it can be used in places where it is difficult to bury the infiltration pipe by the cut-and-cut method, or in places where it is difficult to bury the seepage pipe by the cut-and-cut method, or where it is difficult to bury the seepage pipe by the cut-and-cut method. When implementing the propulsion method, or when constructing a percolation pipe very deep underground, the permeation pipe can be buried extremely smoothly and reliably using the propulsion method to construct the permeation pipe. It has the feature of being able to
