DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A tubular assembly structure 000 according to the present invention.
Is so versatile that a comprehensive description of an embodiment as a use may again hinder its essential understanding. Therefore, first, an embodiment relating to the structure will be mainly described, and then its application will be described.

(First Embodiment of the Present Invention) FIG.
It is sectional drawing of the whole pipe | tube assembly structure 000 regarding various uses of this invention, Comprising: It is comprised from (a) inverted trapezoid, (b) trapezoid, (c) square, (d) hexagon. In addition, an appropriate structure such as a vertically long or horizontally long one is possible. Here, 000 is a tube assembly structure, 100 is a tube, 300 is a covering material, and 700 is a filler. For assembling the entire structure 000, for example, the prior art described in Japanese Patent Application Laid-Open No. 12-80683 can be applied. For example, an alignment frame 500 or the like can be used. Then structure 0
00 can be entirely or partially covered with the covering material 300. The coating material 300 may be installed,
In consideration of the type of fluid such as gas or water to be stored or retained and the interaction with the environment, any material that is permeable or non-permeable can be selected. Both may be used in combination according to the required characteristics.

FIG. 2 is a sectional view of a pipe 10 constituting the structure 000.
0 is a specific structure. Where 100 is a tube, 110
Is a tube wall, 111 is spiral unevenness, 112 is a through hole provided in the tube wall or reinforcing material, and 120 is a reinforcing material. (A),
(B), (c) shows the cross-sectional view, (d),
(E) and (f) are cross-sectional views in the axial direction. According to this, in (a) and (d), irregularities are formed on the inner and outer surfaces of the tube wall 110, and in (b) and (e), spiral irregularities 111 are formed only on the outer surface where the inner wall is smooth. Things.
(C) and (f) show that the reinforcing material 12 is inserted in the pipe 100 in the axial direction.
0 is provided (described later as a third embodiment), and a through-hole 112 communicating with the inside and outside is formed in the tube wall 110 (described later as a second embodiment). Through hole 1
12 can also be formed on the reinforcement 120.

Here, the reinforcing member 120 may be integrally formed inside the tubular body 100, or may be separately formed and inserted into the tubular body 100. Partition walls in the form of partition walls may be provided at appropriate intervals. Also, it is obvious that the through hole 112 can be formed here. The strength of the tube 100 is enhanced by the reinforcing member 120, and the flow state of a fluid such as rainwater flowing into the tube 100 can be adjusted. FIG.
This is a specific structure of the fold surface of the spiral unevenness 111 on the outer surface of the tubular body 100 as viewed from an axial cross section. (A) is a linear repetition, and (b) is a repetition of a curve. (C) shows the periodic structure, which has the same period consisting of repetition of an equal distance with respect to a unit distance in the longitudinal direction. (D) is a combination of a straight line and a horizontal line in the axial direction, and (e) is a combination of a horizontal linear line and a vertical linear line in the axial direction, in which the length of the convex portion and the concave portion are different.
The spiral unevenness 111 can have an arbitrary shape.

FIG. 4 is a view for explaining the features when three tubes 100 are connected and assembled adjacent to each other and bound. This triple binding type is a basic binding structure of the structure 000 and has a very stable structure. Multiple tubes 100
The three or more helical irregularities 111 on the outer surface are brought into contact with each other so as to fit each other, and are connected and converged to each other in the left-right and up-down directions to integrally form a structure 000. The features of the structure 000 are as follows. In the case where the spiral unevenness 111 is formed, basically, the three pipes 100 can be brought into contact with each other so that the spiral unevenness 111 is fitted to each other. Then, it is possible to easily assemble them integrally by connecting and converging with each other in the left and right and up and down directions. Also, the bonding strength is very strong.

A plurality of pipes 100 are connected to each other to form a structure 000.
There are also those that constitute. However, when the tube body 100 having a smooth surface is used, a large number can be connected and bound. However, since there is little binding power,
The cohesive strength as a whole also weakens. Further, in the inside of the structure 000, each tube 100 itself is loose and the positioning is unstable, and the displacement easily occurs easily. This is usually a problem, but paradoxically, removing the bad tube,
Note that there are also some benefits of easy repair.

In the case of using a tubular body having a ring-shaped unevenness formed on the surface, two adjacent ones can be easily bound, but the third one cannot be joined because the binding phase of the unevenness does not match. Moreover, there is a problem that the entire bound end face cannot be flushed. Such structure 000 is large structures 0 three binding essentially adjacent stable repeated sequentially
00, which is inconvenient and difficult to produce a large-scale structure 000.

[0015] In contrast, those in the first embodiment of the present invention, as shown in (a) of FIG. 4, three of the tubular body 100 of the present invention, are adjacent to each other, helical irregularities 111
Are brought into contact with each other so as to fit each other, and are combined and bound. When the spiral unevenness 111 is used, the three pipes 100 can be adjacent to each other, and can be easily combined and combined with the combined phase. Here, when a force acts so that the upper tube 100 moves downward due to its own weight or weight, the lower two tubes 100 receive a force in the direction of separating and moving.
In each of the tubular bodies 100, the spiral ridges 111 are fitted to each other, so that the spiral folds are in contact with each other, and the frictional force acts thereon. In response, a force acts to give a rotational force in the direction of the arrow.

Then, since the upper tube 100 and the lower two tubes 100 are fitted with the spiral unevenness 111, relative movement occurs in the tube axis direction as shown in FIG. It moves slightly in the axial direction. In this case, the contact surfaces of the spiral folds are strongly contacted with each other, and the frictional force causes the respective pipes 1 to contact each other.
A force acts such that the movement in the direction of movement 00 is prevented. Therefore, the binding force between the tubes 100 becomes very strong. Such an effect cannot be obtained at all with a tubular body having a smooth or ring-shaped irregular outer surface. Also, in FIG. 5, when the upper tube 100 is rotated, the lower tube 100 is connected so that the spiral irregularities 111 are fitted to each other, so that the lower tube 100 moves relative to the axial direction. Thereby, the end of the structure 000 in which the three tubes 100 are connected can be adjusted as a whole.

As described above, although each of the pipes 100 is a structure 000 simply connected and assembled, a large number of structures 000 of a predetermined size can be constructed by connecting a large number in the horizontal and vertical directions. Disassembly is also easy, and each tube 100 is easily disassembled into individual pieces by the reverse operation of assembly. During reassembly,
The structure 000 for another use may be diverted. Structure 00
The entire tube 0 is very strong and has an opposing force against the external pressure according to the strength of each tube 100, and the binding force between the tubes 100 is very strong due to the frictional force of the spiral fold of the tube wall 110. However, the whole body is integrated, the respective tubes 100 are hardly separated, and the spiral irregularities 111 are fitted to each other, so that the positions of the respective tubes 100 are less likely to be displaced in the tube axis direction. When the tube 100 is rotated, a relative movement is generated in the adjacent tube 100, so that the end face of the structure 000 is easily adjusted to be flush and the disassembly is easy. Further, a tube 100 having spiral unevenness 111 formed on the surface thereof
Since the pipe 100 itself has a higher rigidity than a straight pipe having the same thickness as the pipe wall 110, the structure 00
Even if it is set to 0, it is possible to configure a material having excellent strength as a whole.

(Second Embodiment of the Present Invention) In a second embodiment of the present invention, as shown in FIG. 2C, a through hole 112 is formed in a tube wall 110. In this way, it becomes easy to take in fluid such as rainwater from the through hole 112, and even in the inside of the structure 000, each pipe 100
The flow of the fluid stored and retained between the fluids is performed smoothly. By adding the through-hole 112, such convenience can be added. This through hole 112
Can be provided also on the reinforcing member 120 and the water intake pipe 800. (Third Embodiment of the Present Invention) According to a third embodiment of the present invention, as shown in FIG. 2 (c), a reinforcing member 120 is provided inside the pipe 100 in the axial direction. The reinforcing member 120 may be provided integrally inside the tube 100,
It may be formed separately and inserted into the tube 100. The axial direction may be arranged partially or continuously with respect to the length direction. The addition of the reinforcing material 120 greatly enhances the strength of the individual pipes 100, so that the entire structure 000 can be installed at a location where the external pressure is extremely high. In the example of this figure, the cross section is substantially cross-shaped, and is partitioned into partition walls at predetermined intervals. (Fourth Embodiment of the Present Invention) FIG. 6 is a view showing a long tube 140 and a short tube 130 of the tube 100. FIG. 7 is a diagram showing that the long pipe 140 and the short pipe 130 are combined and extended and added in the pipe axis direction. (A) is a transverse sectional view, (b) is an axial sectional view. The extension can be performed sequentially while shifting the position of the connection portion. In this way, it is not necessary to use an adhesive or special connection means. In addition, there is no need to make a proper contact at the connecting portion to perform the alignment, and the position may be slightly shifted. As described above, it is possible to use the long pipe 140 and the short pipe 130 to extend and extend the pipe in the axial direction. It can be easily collapsed if necessary. In addition, when the facility of the structure 000 becomes unnecessary, since no adhesive or special connection means is used, it is easily dismantled, and each pipe 100 is collected and subjected to a simple washing process such as washing with water. Collected as raw material and can be reused. For reuse, it can be used for a different purpose than before dismantling.

FIGS. 8 and 9 are views for explaining a situation where the applied external pressure is dispersed when the external pressure is applied to the tubular body assembly 000 of the present invention. In FIG. 8, when an external pressure is applied from above as indicated by a large black arrow, the external pressure is sequentially dispersed and applied to each of the adjacent pipes 100 as indicated by a small black arrow, and the lowermost pipe 100 Are, for example, distributed over a fraction of the force. In FIG. 9, when an external pressure is applied obliquely from above as indicated by a large black arrow, the lowermost pipe 100 is dispersed into, for example, a fraction of a force. In this way, even if an external pressure is applied, the force applied to each of the pipes 100 is dispersed, so that it is possible to provide a very strong pipe assembly 000 that can easily oppose the external pressure.

FIG. 10 shows a specific tube assembly structure 000.
This is obtained by providing the coating material 300 in the configuration shown in FIG. The structure 000 of the three tubes 100 is connected in an upward direction, and has a rectangular cross section. End plates 200 are provided on both sides. This end plate 200 is also used as a shape-retaining material, and can also be used as a permeable material or a non-permeable material. Naturally, reinforcing means can be added as appropriate in order to enhance the strength of the entire tube assembly structure 000. A reinforcing frame may be used, or a conventionally known means may be used. FIG. 11 shows a structure 000 composed of three tubes 100 as a basic unit. It is also possible to arrange the filler 700 in the gap. Such a structure 000 can be configured in advance as an intermediate structure, and these can be further combined to form a large-scale structure 000.

It is convenient to use various synthetic resins for the material of the tube 100. Either hard or soft material may be used, and it should be arbitrarily selected according to required specifications.
In terms of size, any method can be used as necessary, and a material having a diameter exceeding human height or a device that can protect one signal line or one electric wire may be used. The material is usually polypropylene, polyethylene or the like, but may be a collected and recycled synthetic resin. In addition, since it can be used repeatedly and is not discarded, use of vinyl chloride is also conceivable. In addition to various synthetic resins, it is possible to select a steel pipe, a cast iron pipe, a stainless steel pipe, an earth pipe, a sintered metal pipe, or the like, which has any property such as iron, non-ferrous, ceramic / magnet, or ceramics. Alternatively, the pipe body 100 itself may be provided with water permeability as a microporous tube. The same material as that of the main body of the tubular body 100 can be selected for the reinforcing member 120. However, things degrade spontaneously when used, and their natural life span,
Since there is deterioration, it is necessary to consider the neighborhood.

Hereinafter, various uses of the present invention will be described. The concept of use is derived from various features of the structure 000. The first is the direction in which the outer shell is used in view of the fact that it is lightweight, has a large volume, and can firmly resist external pressure. This can be considered as a lightweight embankment material. What is necessary is just to install in a predetermined position, coat | cover thinly with earth and sand, etc., and construct a structure appropriately on it. Substantially no earth and sand of the coating is required.

Second, it is used as a buoyant body utilizing buoyancy when the whole is closed. Used as a support for piers and floating bridges. If the buoyancy is controlled by partially storing water or the like in the pipe 100, the cage and the tank can be fixedly supported at a predetermined water depth. Third, each pipe 100 is used as a storage tank for storing a predetermined gas, fluid, or the like. It can be installed anywhere on the ground, underground, or underwater, and can store and store a specified fluid. It may be constructed as an underground dam. If the buoyancy is controlled in the water, it can be installed at a constant water depth at any temperature.

Fourth, signal lines, electric wires,
It is used as a protective tube and a sheath tube by accommodating a cable such as a steel cable and a pipe such as a gas pipe. Positioning of each pipe body 100 is reliable, and it is hard to cause displacement, so that protection is reliable, and it can be applied to places where landslides are likely to occur or under high pressure, so that internal wires, ropes, pipes, etc. can be suitably protected. It can be used as a cultivation room for other cableways, evacuation routes, storages, and shiitake mushrooms. Fifth,
It is used as a storage tank for rainwater and as a permeable tank. In a pond in a rural area, or in an urban area, underground or semi-underground, temporarily collect rainfall such as torrential rain and infiltrate into the underground at a later time, drain into rivers, or use as water Pump out and use. A desired auxiliary device such as an intake pipe 800, a drain pipe, a side ditch, an inflow ditch, or a drain ditch can be added. Even if each household has a small-scale equipment, rainwater can be stored as middle water without directly flowing from the roof gutter to sewage, and can be used for garden watering, car washing, etc. It can also be infiltrated into groundwater. Even in an arid zone such as a desert, rainwater during the rainy season or melted snow and ice can be collected and pumped out during the dry season to be used as an oasis facility.

By appropriately utilizing the permeability and non-permeability characteristics of the coating material 300, it is possible to arbitrarily adjust whether to stay or permeate. In addition, expansion, reduction, movement are easy,
In urban areas, etc., facilities such as parks and playgrounds can be constructed on the upper side.
The construction of a permeable tank is possible, and the land can be effectively used. The assembly of each invention of the present application may be assembled at a predetermined place such as a factory and carried to an installation place. Also, it may be assembled and installed on site. In addition, the ground at the local installation site may be dug and assembled inside. For the assembling, any known auxiliary device such as the alignment frame 500 may be appropriately used.

【The invention's effect】

The structure of the first embodiment of the present invention is a structure 000 in which a large number of tubes 100 each having spiral irregularities formed on the outer surface are simply connected and assembled. By connecting a large number of them, a multi-purpose structure 000 having a predetermined size can be constructed. Although various uses of the structure are possible, the first lightweight embankment material, the second buoyancy body, the third storage tank, the fourth protection tube, and the like using the lightness are used.
The use of cableways, fifth storage and permeable tanks is possible. The entire structure 000 is very strong and resistant to external pressure depending on the strength of each tube 100, and the tube wall 1
Due to the frictional force of the ten spiral folds, the binding force between the tubes 100 is very strong, and each tube 100 is difficult to separate,
Since the helical irregularities 111 are fitted to each other, it is difficult for the respective pipes 100 to be displaced in the pipe axis direction, and when an arbitrary pipe 100 is rotated, the adjacent pipes 100 are relatively moved. Therefore, it is easy to adjust the end face of the structure 000 flush. It is easy to disassemble, and each tube 100 can be easily disassembled by the reverse operation of assembly. Therefore, it can be recovered as a raw material by a simple treatment such as washing with water, and can be reused. The second embodiment of the present invention is particularly suitable for the use of the fifth storage and permeable tank. Since the third embodiment of the present invention has high strength, it is particularly suitable for use of the fourth protective tube and the cableway. Since the fourth embodiment of the present invention can be freely added or removed, any of the above applications may be used, but a large-scale one is particularly suitable.
