The present invention is based on separating the receiving portion and the drainage by covering the outer circumferential surface of the drain pipe (2) with a mesh filter surrounded by a reticular filter material, and efficiently collects the groundwater over a long period of time and resists external pressure. This large and easy to manufacture culvert drainage pipe.

When constructing ground drainage method, it is most important to note that it is easy to collect and collect only water efficiently by separating soil particles. However, the conventional ground drainage method is a method of changing the ground with jade and gravel to form a drainage space on the jade roof, etc., or by embedding perforated pipes such as synthetic resin and concrete made with a catchment hole in which independent perforations are collected. There were construction methods that could carry out ground drainage. However, in the former method, there is a problem that it is difficult to secure the durability of the collection and drainage because the holes between the jade stones are blocked quickly. On the other hand, in the latter method, since the pipe itself needs to function as a water collecting pipe and also as a drain pipe, as shown in FIG. It can be said as the upper part (b) except the height part (a). Therefore, there is a problem in that water collection is difficult to be performed because of limitations on the number of perforated snow removal sites and the number of perforations. In addition, since the water level in the pipe was constrained shallowly about the lower quarter of the pipe (compared to the water levels shown in Figs. 5 and 18), the drainage efficiency was not good. In addition, the hole of the hole (c) is blocked in order to achieve not only the hydraulic action of the through hole (c) and the water but also the filter action at the same time, so that the water collecting at the blocked portion of the hole is impossible at all, making it difficult to secure the durability of the collector. There was this.

An object of the present invention is to provide a culvert collecting pipe of a novel structure that solves a mainly related problem of the blind drainage method. The culvert drainage pipe (1) of the present invention is a single or plural number of ordinary mats (3) by interposing the outer peripheral surface of the drain pipe (2) having the inlet opening (6) for inflowing water through the reticular filter material (11). The ordinary mat 3 is coated in order to form an axial water channel 7 extending in the axial direction of the drain pipe 2, so that the outer peripheral surface portion of the drain pipe 2 is normally connected. In the state covered with the body mat 3, the axial water channel 7 is the contact portion between the outer circumferential surface portion 5 of the drain pipe 2 and the reticular filter material 11 or the outer circumferential surface 5 of the ordinary body 9 and the reticulated filter. As a contact portion of the ash (11), it is characterized in that connected to the water passage (31).

When the culvert drainage pipe 1 of this invention is appropriately connected and embedded in the soil excreted by the predetermined | prescribed drainage slope in the excavation | disconnection hole 40, the groundwater will be efficiently filtered and collected according to the normal mat 3. . The water-permeable part 31 is used as a contact portion between the outer circumferential surface portion 5 of the collected drainage pipe 2 and the reticular filter material 11 or a contact portion between the outer circumferential surface portion 5 of the ordinary body 9 and the reticular filter material 11. It passes through the main direction (for example, the F1 direction shown in FIG. 5), and flows through the axial channel 7 to the axial direction of the culvert drainage pipe 1 (for example, F2 shown in FIG. 1). Direction, and the groundwater moves freely by changing the direction of flow due to the circumferential and axial movements of the water, and flows into the drain pipe 2 from the inlet opening 6 and drains the water. (2) It flows smoothly inside and is discharged from the end. Here, the filter action of the culvert drainage pipe 1 will be described. Particles such as soil particles contained in the groundwater are separated and trapped primarily at the conventional body connection 29 of the conventional body mat 3, and the connection part ( The microparticles introduced in 29 are separated and captured secondaryly in the water passage part 31 so that the culvert drainage pipe 1 effectively performs a dual filter action.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 5, the culvert collection and drainage pipe 1 of the present invention is set to a unit length by covering the outer peripheral surface of the drainage pipe 2 with a normal mat 3 interposed with the reticular filter material 11. (See Figure 1). For example, the drain pipe 2 has a circular pipe shape with a smooth outer circumferential surface, and the inlet openings 6 and 6 for water inflow are opposed to the outer circumferential surface portion 5 at predetermined intervals while being gradually biased upward. It is laid in state (refer FIG. 1, FIG. 5). The ordinary mat 3 is connected to the normal body 9 to form an axial water channel 7 extending in the axial direction of the drain pipe 3, and in this embodiment, the mesh filter so that its front and rear are reticulated. It is covered with ash 11 (see also FIG. 4). This will be described in detail below.

The ordinary body 9 is an integrally molded product made of synthetic resin, and the two spaces 14, adjacent to each other as waterways are formed by allowing both ends of the central wall 12 to be wound in the reverse direction as shown in FIG. 2 and FIG. 15) and a cross section in which openings 16 and 16 are formed as water inlets between the winding end and the central wall 12 protrude to both sides between the two winding ends on the central wall 12 of the S-shaped cylinder. The protrusions 17 and 17 are formed so that the protrusions 17 and 17 may be provided on the outer surfaces of the spaces 14 and 15 so as to protrude from the coupling protrusions 19 and the coupling protrusion grooves 20 opposite to each other. The engaging protrusion 19 extends the stop parts 22 and 22 on both sides of the tip end portion of the protrusion 21 so that its cross section is substantially T-shaped. In addition, the coupling protrusion groove 20 has a groove 25 into which the front end side portion 23 of the coupling protrusion 19 is inserted to be formed against the pair of protrusion pieces 26 and 26, and each protrusion The front end portions of the pieces 26 and 26 extend so as to face the stationary pieces 27 and 27 curved in a semicircle to engage the stop portions 22 and 22. In addition, the protruding length of the engaging projection 19 is set slightly larger than the depth of the groove of the engaging projection groove 20.

However, as shown in FIG. 3, the front end side portion 23 of the connection protrusion groove 19 is inserted into the connection protrusion groove 20 to play against the elastic action of the two protrusion pieces 26 and 26. When the stop 22 and the stop piece 27 are engaged, the engaging protrusion 19 becomes impossible to detach from the engaging protrusion groove 20, thereby connecting the ordinary bodies 9 and 9 to each other. It becomes. The ordinary body connected in this way becomes flexible in a certain way at its connecting portion 29, and the gap G formed at the connecting portion 29 actively inflows ground water as described later. The ordinary body 9 having such a configuration is set to approximately the same length as the total length of the drain pipe 2, and is connected in sequence as described above to form a normal mat 3 surrounding the outer peripheral surface of the drain pipe 2. (See Figure 4). In addition, in order to prevent the collapse of the ordinary mat 3, it is preferable to connect the ordinary bodies with adhesive tapes (not shown).

In addition, in this embodiment, the ordinary mat 3 thus formed is accommodated in the mesh filter material 11 in the form of a bag, for example, and as shown in FIG. 4, before and after the normal mat 3 is shown. Is covered with the mesh filter material 11. The ordinary mat 3 covers the outer circumferential surface of the drain pipe 2 with the mesh filter material 11 interposed therebetween, and surrounds the drain pipe 2 with the normal mat 3 covered with the mesh filter material 11. The body 9a and the both ends 9a are combined with each other by combining the coupling protrusion 19 and the coupling protrusion groove 20 (see FIG. 5), and the mat 3 and the drain pipe 2 as necessary. ) Is bound by a binding member (not shown) such as adhesive tape or steel wire. The culvert drainage pipe 1 of this invention comprised in this way is the contact part of the outer peripheral surface part of the drain pipe 2, the mesh filter material 11, or the outer peripheral surface part of the normal body 9, as shown to FIG. 1, FIG. And space portions 14 and 7 which are mainly opened inward by axial water extending in the axial direction F2 of the drain pipe 2 connected to the water passage portion 31 as the contact portion of the mesh filter material 11. do. In this state, the other space 15 of the ordinary body 9 is opened outward. In addition, the space portion 15 that is opened outward is often used as the axial channel 7, but is described later.

In addition, in the invention, the drain pipe 2 may be covered in double or more times as the normal mat 3 depending on the pipe diameter of the drain pipe 2 or the like. In addition, as shown in FIG. 6, for example, the ordinary mat 3 can form a plurality of ordinary mat 3 having a unit width together with the connecting portion 32 at its side end. Next, the operation of the culvert drainage pipe 1 of the present embodiment will be described while explaining an example of the method of constructing the ground drainage method using the culvert drainage pipe 1 of the present embodiment.

As shown in Figs. 7 and 8, the culvert drainage pipe 1 is used such that, for example, the connecting pipe 33 is used so that its inlet opening 6 is located on the side (see Fig. 5). And (2) are disposed at a predetermined drainage slope in the excavator opening (%) with the end portions 35 and 35 sequentially connected. At this time, the outside of the culvert drainage plate 1 is surrounded by a filter layer 37 formed of filter material such as gravel, stone, sand, chaff, etc. and embeds the culvert drainage pipe 1 filter layer 37 in the soil.

Therefore, the ground water is filtered through the filter layer 37 made of gravel, gemstone, and the like, and the filter medium 11 forming the outermost layer of the culvert drainage 1. The connection part 29 leads to the water passage part 31, and particles such as soil particles contained in the ground water passing through the mesh filter material 11 are separated and captured by the connection part 29. In particular, in the present embodiment, the culvert drainage pipe 1 has a space portion 15 formed outwardly by the ordinary body 9, and the earth excrement and the like in the ground water directed to the connection portion 29 are connected to this connection portion ( It enters into the space part 15 which turned outward in the previous step to reach 29, and is captured by this space part 15. FIG. The space portion 15 opened to the outside performs a filter function in this way. Therefore, the amount of particles such as soil particles directed to the connecting portion 29 is reduced by that much. The groundwater passing through the connecting portion 29 passes through the water passage 31 and moves in the circumferential direction F1, and at the same time, moves in the axial direction F2 in the axial direction F2. Due to the phenomenon that the movement of the water in the axial direction F2 joins, the groundwater flows freely while moving in the direction of flow, and enters the drain pipe 2 from the inlet opening 6 (see FIG. 5). Since the water is separated and captured in the water passage part 31, clean water having less soil particles flows in from the inflow opening 6 into the drain pipe 2, and thus the inflow water introduced into the drain pipe 2 flows into the drain pipe 2. It flows smoothly and exits at its end. In addition, the groundwater is configured to be moved in the main direction (F1) and the axial direction (F2), for example, when the amount of water is excessively collected in the water collecting portion or when the inlet opening formed in the water collecting portion is blocked. Edo water flows quickly in the axial channel 7 downward and moves in the circumferential direction and flows into the predetermined inlet opening 6.

In fact, since the axial channel 7 is provided in parallel, even if the soil particles and the like in the axial channel 7 are deposited, the influent flows smoothly by appropriately selecting the channel flowing along the natural flow. In addition, especially in this embodiment, since the culvert drainage pipe 1 is provided with the space part 15 which opened the outer side, even if the quantity of water which should flow into the drainage pipe 2 becomes excess, for example, the water flow part 31 ) Once reached, flows out from the connecting portion 29 of the ordinary body and flows into the space portion 15 which is appropriately opened outwards, passing through the connecting portion 29 again at a suitable place on the downstream side to reach the water passage portion 31. And, it can be seen that the flow into the drain pipe (2) as above. In addition, when the amount of groundwater to be collected at any of the connecting portions 29 is excessive, a portion of the groundwater flows into the space 15 opened to the outside and flows downstream, and the connecting portion 29 at a suitable place on the downstream side 29 It is considered to reach the water passage part 31 through (). In fact, the action of the outer opening 15 is to act as the axial channel 7 and to assist the drainage in the axial channel 7 with the opening 14 to the inner side.

9 is a view of connecting the drain pipes 2 and 2 to each other using the adhesive tape 39, so that the connecting portions 40 of the mats 3 and 3 are generally positioned at the center of the drain pipe 2, respectively. Since the circumference | surroundings of the drain pipe 2 are coat | covered with the normal mat 3 so that it may be located, and the connection part 40 of the normal mat mutually shall be coat | covered with the adhesive coupling tape 41 on the mesh filter material, the drain pipe 2 and the normal body The culvert drainage pipe 1 which integrated the mat 3 in the stable state is shown. In addition, the inlet opening 6 is intimately formed in the shape of the culvert drainage pipe 1, and the side end portions of the normal mat 3 are connected to each other by a mesh filter material 11 covering the front and rear of the normal mat 3. As a side end portion of Fig. 1, the connecting rod portions 42 and 42 (see Fig. 11) can be integrated with an iron fence or the like as shown in Fig. 10. In the culvert collecting and draining pipe 1 configured as described above, the coupling tape 39 wound around the joints of the drain pipes 2 and 2 is disposed between the circumferential surface of the drain pipe 2 and the inner surface of the ordinary mat 3. It has a function of forming the flowing water gap 42. 12 to 17 are cross-sectional views showing another embodiment of the ordinary body 9 in a connected state thereof and a state arranged around the drain pipe 2, and in the same manner as in the above embodiment, the normal connecting portion 29 The groundwater introduced from the flows in the circumferential direction and the axial direction and flows into the drain pipe 2. 12 to 14 show the use of a conventional body modified from a part of the sigmoidal body as in the above embodiment, and in particular, FIG. 13 shows a part of the conventional constituting the normal body mat 3. It shows that the sieve connected the inner opening space 14,14 mutually or the outer opening space 15, l5 so that mutually adjacent each other.

In this invention, the aspect which provided the inflow opening part 6 in the drain pipe 2 is not limited to what was shown in the said Example, For example, the inflow opening part with comparatively small diameter can also be formed in a dispersed state. In addition, as shown in FIG. 18, the drain pipe that allows the inflow openings (pores) to be laid is not excluded from the present invention.

The outer peripheral surfaces of the culvert drainage pipe 1 and the drainage pipe 2 of the present invention are covered with the reticular filter material 11, and then, the cover water port is covered with the ordinary body mat 3, and constituted.

The effects of the present invention are described below.

(1) Since the culvert collection and drainage pipe of the present invention separates the water collecting portion and the draining portion as described above in (a) and (b) below, the water collection efficiency and the drainage efficiency are extremely good, so that the groundwater is efficiently It not only collects water, but also maintains a valid water drain for a long time.

암 Since the culvert drainage pipe of the present invention covers the outer circumferential surface portion of the drain pipe with a single or plural number of ordinary mats through a mesh filter material, the internal space formed by the culvert drainage pipe is formed by various kinds of spaces (mainly formed by reticular bodies, usually Spaces formed on the body mat and spaces connected to each other by the spaces in the drainage) so that each of these spaces can independently and effectively collect and drain the water and the soil particles. It is. Accordingly, the culvert collection and drainage pipe of the present invention is completely different from the conventional perforated pipe configured to perform the water inflow action and the filter action in the same perforation, and efficient collection is possible. Since the ground water moves in the circumferential direction and the lateral direction, even if a part of the inlet opening formed in the drain pipe is blocked by the phenomenon of water movement in the circumferential direction and the axial direction, the ground water of the blocked part is The hole flows rapidly to the downstream side of the inlet opening which is blocked, and flows into the drain pipe from the inlet opening that exists on the downstream side. In the case of judging such an inflow opening, the ground water of the circumferential portion not only flows into the inflow opening, but also the ground water collected in the portion separated therefrom. As is clear from the above, the culvert drainage pipe of this invention has the permanence of water collection.

암 The culvert drainage pipe of the present invention has a dual filter action (primary separation, capture, and secondary separation of soil particles at the water passage) as described in the above section. Therefore, clean water with small particulates flows into the inlet opening of the drain pipe. Therefore, in the drainage pipe, the inside of the pipe becomes fine due to the accumulation of soil particles, and there is no fear of deterioration of the drainage. Since small clean water of such granular material flows into the inlet opening of the drainage pipe, it is also possible to set the inlet opening large. As a result, the water introduced into the axial water flows quickly into the drain pipe even with a small number of the inlet openings. Therefore, since a layer of water is formed on the outer circumferential surface of the drain pipe, the inlet opening is laid at the uppermost portion of the drain pipe, so that the water level in the drain pipe can be set high, unlike the above-described conventional hole drain pipe. In other words, the flow volume in a drain pipe can be enlarged. In addition, according to the installation error of the culvert drainage pipe, the deviation of some drainage occurs or is subjected to partial pressure to ensure the drainage action of the drainage pipe even if the culvert drainage pipe is submerged in a secondary ring. As is clear from the above description, the culvert drainage pipe of the present invention has an effective drainage durability.

(2) The culvert drainage pipe of the present invention has a structure as a "dummy pipe" in which the circumference of the drain pipe is covered with a normal mat, and is elastically impregnated, and is a simple type of body, which has a significantly higher load capacity than conventional perforated pipes. Less damage

③ The culvert drainage pipe of the present invention can save the filter material as compared with the construction of the ground drainage method using the perforated pipe described in the beginning to perform the double filter action as described above, the filter material Can alleviate the conditions for quality.

As such, it is possible to reduce the construction cost and shorten the air by reducing the material cost and construction time according to the culvert drainage pipe of the present invention.

(4) Since the culvert drainage pipe of the present invention has a structure in which the outer circumferential surface portion of the drain pipe is coated with the normal body mat by connecting the ordinary bodies to each other, the skilled person does not need the skill to manufacture and can be easily performed. In addition, it is possible to employ a conventional perforated pipe as a drain pipe, so that the manufacturing cost can be reduced.

(5) In the present invention, the outer circumferential portion of the drain pipe (2) having the inlet opening (6) is covered with the ordinary mat (3), which means that the entire outer circumferential surface portion of the drain pipe (2) is covered with the ordinary mat (3). Rather, the outer peripheral surface portion of the drain pipe 2 is covered with the normal body mat 3 so as to cover the inflow opening 6 with the predetermined width portion removed in the long water direction thereof. An example of this is as shown in FIG.

The culvert drainage pipe 1 shown in this figure has a mesh shape except for the portion of the outer circumferential surface of the drain pipe 2 in a predetermined width portion in the longitudinal direction thereof (in the use state, the lower end portion in the longitudinal direction as shown in the example) and 45. It is covered with the ordinary mat 3 covered with the filter material 11, and each of the drain pipes 2 and the ordinary mat 3 is bound by a binding member (not shown) such as tape or solid line. , The inflow opening 6 is formed adjacent to the upper side of the drain pipe 2.
