A surface water collection port (8a) that is capable of collecting water flowing down from an upper side of the slope is installed in the lateral vein pipe. Rainwater flows from the surface water collection port of the lateral vein pipe into the lateral vein pipe. Osmosis water inside the ground flows through the water collection pipe into the lateral vein pipe. Both the surface water and the osmosis water are excluded from the slope ground after flowing into the midrib drainage and flowing downward, and can be excluded effectively. Drainage of the osmosis water is performed by the midrib drainage and lateral vein pipe which is common to surface water collection means. Therefore, efficiency can be high and manufacturing costs can be reduced.

Description

Drainage structure of inclined surface ground and construction method thereof

The present invention relates to a drainage structure for preventing a slope of a soil or a cut soil or the like from collapsing due to the action of water, and a construction method therefor.

It falls on the slope of the slope formed by the soil or cut soil, and erodes the slope when it flows down. In addition, there are many cases where the permeated water in the infiltrated soil due to rainfall becomes a cause of collapse of the slope.

Therefore, in the past, on the slope of the soil or the cut soil, there are many cases where the surface water discharge works for the surface water is excluded (see Patent Document 1, etc.), and the construction collects the permeated water permeated in the soil for drainage. There are also many cases of groundwater drainage projects (see Patent Document 2, etc.).

Patent Document 1 contemplates a case where a vertical inclined surface drainage structure in which rainwater accumulated from the surface layer of the normal surface flows down the inclined surface is provided on the inclined surface of the side of the road built with the soil or the cut soil, or The rainwater accumulated in the water collecting tank in the middle of the slope is drained into the lower collecting tank.

Patent Document 2 is a process in which a plurality of drain pipes provided with a plurality of drain holes are inclined at a substantially horizontal or external (beveled) outer end portion so as to be inclined downward and into a sloped surface, and the permeated water in the soil is used. The drain hole of the drain pipe is introduced into the pipe, and is drained from the outer end (outer surface), thereby preventing the collapse of the slope of the water.

The vertical drainage groove, which is a longitudinal slope-drainage structure of the inclined surface described in Patent Document 1, cannot exclude rainfall in a wide range of slopes. Therefore, the unexcluded rainwater penetrates into the ground plate and is stored, and the stored permeated water becomes the cause of the collapse of the slope.

However, it is known to provide a lateral groove on the inclined surface, that is, a small-sized drainage groove, and to connect it to the vertical drainage groove, and to eliminate the rain in the wide range of the slope. However, the inclined drainage structure formed by the vertical drainage groove and the small drainage groove is effective for preventing the erosion of the inclined surface, and the rainwater penetration into the soil can be reduced, but the permeated water in the soil cannot be excluded. Therefore, the unexcluded rainwater penetrates into the ground plate and is stored, and the stored permeated water becomes the cause of the collapse of the slope.

Referring to Patent Document 2, a process of driving a plurality of drain pipes having a drain hole into a slope is not sufficient as a method of removing permeated water in the soil. That is, even if the permeated water introduced into the soil by the drain pipe is discharged to the outside, that is, the inclined surface, the water discharged to the inclined surface still erodes the inclined surface. Further, if the slope is covered with shotcrete or the like in order to prevent the erosion of the slope, the vegetation growth of the slope cannot be performed.

Although the two processes of the process of setting the above-mentioned vertical drainage channel and the process of installing the drainage pipe with the drainage hole are also considered, even if the two processes are simply constructed on the same inclined surface, the construction property, the construction cost or the drainage At various points such as performance, it is still difficult to say that it is an effective and practical construction method.

The present invention has been made in view of the above-mentioned background, and an object of the present invention is to provide a drainage structure for a sloping ground plate, which mainly utilizes a slope formed by a soil or a cut soil, and can effectively exclude both surface water and permeate water, and is under construction. Excellent in various points such as sex, construction cost or drainage performance.

A drainage structure for a sloped ground plate according to the invention of the first aspect of the present invention is characterized in that: a main vein drainage path having a sloped longitudinal direction is provided on the slope surface; and the main vein drainage road is connected to the main vein drainage road in a downward slope from the inclined surface. The side vessel of the main vein drainage road is arranged with at least a part of the surface protruding from the ground surface; the water collecting tube having a plurality of water collecting holes on the outer peripheral surface is inserted horizontally or several upwards from the oblique surface toward the ground plate, and is inserted into the side vessel The end portion of the surface side of the water collecting pipe is connected; and the side vascular tube has a surface water collecting port which is open on the ground surface and can collect water flowing from the upper side of the inclined surface to collect water on the upper side of the inclined surface of the radial direction.

The technical solution 2 is the drainage structure of the inclined floor of the first aspect, wherein the side vessel is arranged to block and accumulate the soil sand flowing from the upper side of the inclined surface in such a manner that at least a part protrudes from the ground surface.

In the above, the "blocking and accumulating soil sand" includes moving the side vessel downward from the slope by, for example, a pile or the like, except that at least a part of the side vessel protrudes from the ground surface and ensures height.

The technical solution 3 is the drainage structure of the inclined floor of the first aspect or the second aspect, wherein the support plate is attached to the connection portion between the water collection pipe and the side vessel.

The technical solution 4 is the drainage structure of the inclined ground plate according to any one of the first to third aspects, wherein the side vascular system is disposed in a state in which one of the sections is partially buried in the soil.

The fifth aspect of the invention is the drainage structure of the sloped ground plate according to any one of claims 1 to 4, wherein the surface water collection port is provided in a short tube installed in a hole opened in the side vessel.

The drainage structure of the inclined ground surface according to any one of claims 1 to 5, wherein a lower side of the inclined surface adjacent to the radial side of the side vessel is provided to prevent the side vessel from moving below the slope pile.

The solution 7 is the drainage structure of the inclined floor of any one of Claims 1 to 6, wherein: One layer to a plurality of layer rod members are overlapped on the side vessel.

The drainage structure of the sloped ground plate according to any one of the first to seventh aspects, wherein the side vessel is a ground side half body which is divided into a connection hole in which an end portion of the surface side of the water collection pipe is connected The eccentric structure of the outer side half of the opposite side.

The invention of claim 9 is characterized in that, in the method of constructing a drainage structure for a sloped floor of a drainage structure of a sloped ground according to any one of claims 1 to 8, the side vessel and the water collection tube are provided in each side vein. A connecting hole for connecting the water collecting pipe corresponding to each water collecting pipe to be connected to each side of the blood vessel is preliminarily provided on the tube; and each of the side blood vessels is to be connected to each side blood vessel at a predetermined insertion position. Each of the water collecting tubes is inserted into the grounding plate; then, the end portions of the surface side of each of the water collecting pipes inserted into the grounding plate are respectively inserted into the connecting holes of the side vascular tubes, and the side vascular tubes are disposed on the inclined surface, and the water collecting tubes are The end of the surface side of the ground is connected to the side vessel.

The invention of claim 10 is characterized in that, in the drainage structure of the sloped floor in the drainage structure of the inclined floor of the construction technique 8, the side vessel and the water collection pipe are provided, and the blood vessels on each side of the halved structure are provided. On the ground side half body, a connection hole for connecting the water collection pipes corresponding to the respective water collection pipes to be connected to the respective side vessels is provided in advance; on each of the side blood vessels, a predetermined insertion position is to be connected. Inserting the water collecting pipes of the respective side vessels into the ground plate; then, the sides of the surface side of each of the water collecting pipes inserted into the ground plate are respectively inserted into the respective connecting holes of the ground side half body of the side vascular tube, and the respective sides are The ground side half of the vessel is placed on the inclined surface; then, the outer side half of each side vessel is covered and joined to the ground side half body to be integrated.

In the present invention, the rain falling to the slope flows down the slope, and the surface water collection port of the side vessel protruding from at least a part of the surface from the ground surface enters the side vessel, flows in the side vessel and flows into the main vein of the oblique longitudinal direction. The drainage path flows down the main vein drainage path, and drains to, for example, a drainage path provided at a lower portion of the inclined surface.

Therefore, it is possible to effectively prevent the erosion of the slope caused by the surface water during rainfall. Moreover, since there is less rainwater that permeates into the interior of the site during rain, the amount of permeated water that causes the collapse of the slope can be reduced.

In addition, the permeated water in the groundwater that penetrates into the rainwater of the inclined surface is introduced into the water collecting pipe from the collecting hole of the collecting pipe, and flows into the side vessel along the water collecting pipe which flows toward the side vessel at a horizontal or several descending slope. The flow in the side vessel of the descending slope flows into the main vein drainage passage, and flows down the main vein drainage passage in the same manner as described above, and drains to the drainage passage at the lower portion of the inclined surface.

In this way, since the permeated water in the site is collected by the water collecting pipe, the water is not drained to the surface of the ground, but is drained to the lower part of the inclined surface through the side vessel and the main vein drainage road, so that the water collected by the self-collecting pipe is only on the surface of the inclined surface. The flow will not penetrate into the ground again and will not erode the slope.

As described above, according to the present invention, both the surface water and the permeated water of the inclined floor can be effectively excluded.

Further, since the drainage of the sloping surface of the inclined surface to the lower portion of the slope is performed by the side vessel and the main vein drainage path common to the surface water collecting mechanism, it is extremely effective and has good workability, and low-cost construction can be realized. In this way, the present invention is effective in combining various aspects of the surface drainage work for the surface water drainage of the inclined surface and the groundwater removal engineering for removing the permeated water inside the ground.

Moreover, since the covering slope is only the main vein drainage channel and the side vessel, the area covered by the slope is narrow, so that sufficient vegetation growth can be performed on the slope.

The water collecting pipe inserted into the inclined ground plate is the same as the steel bar inserted into the reinforcing geotechnical method. In the case of the reinforcing sloped ground plate, as in the case of the technical solution 3, when the support plate is attached to the connection portion between the water collecting pipe and the side vessel, the bending/pulling resistance of the water collecting pipe is further improved by the supporting force of the supporting plate. Effectively, it can further effectively prevent the small-scale collapse of the surface of the ground.

According to the second aspect, the rain falling to the slope flows down the slope, is blocked by at least a part of the ground protrusion of the side vessel protruding from the ground surface, and directly reaches the surface water collection port of the side vessel, or along the descending slope. After the side vessel flows, it reaches the surface water collection port of the side vessel and enters the side vessel from the surface water collection port, and is drained to, for example, a drainage channel provided at a lower portion of the slope, as in the above.

Moreover, after the construction, the soil sand flowing down the slope due to the rain is blocked by the side vessel protruding from the surface of the ground and is deposited on the upper side of the slope of the side vessel, and the accumulated soil sand accumulated here usually also contains the humus soil. Or the leaves are not firmly pressed, such as leaves, which are soft and soft. Therefore, the rainwater that flows down the slope and falls to the above-mentioned accumulated soil sand during rainfall is likely to penetrate into the lower portion (bottom portion) of the accumulated soil sand, and the surface water collection port from the side vessel enters the side vessel. The soft, accumulated soil sand is good for effectively collecting rainwater that has fallen to the slope, and achieves a higher surface water collection performance at a very low cost.

Further, since the accumulated sand deposited on the upper side portion of the slope of the side vessel after the construction is usually soft soil sand including humus soil or fallen leaves, the soil portion is particularly suitable for vegetation growth.

As shown in the fourth aspect of the invention, if the side vessel is disposed in a state in which one part of the section (for example, a semicircular portion) is buried in the soil, especially when the main vein drainage path is grooved, the side vessel can be not damaged. The function of accumulating the soil sand allows the internal water to smoothly flow into the groove-shaped main vein drainage path, and the connection structure with the groove-shaped main vein drainage path can be simplified, and the connection work can be simplified.

In addition, since a part of the blood vessel is buried in the soil, the contralateral vessel moves to the lower side of the slope to act as a barrier. Therefore, when the slope of the slope is gentle, the lateral vessel can be omitted. The mechanism that moves on the lower side of the face.

According to the sixth aspect of the invention, when the pile for preventing the side vessel from moving to the lower side of the slope is provided, in particular, when the slope of the slope is steep, it is possible to surely prevent the side vessel from moving to the lower side of the slope.

According to the seventh aspect of the invention, when the rod-shaped members such as the thinned material are superimposed and increased on the side vessel, the amount of accumulation of the soil sand flowing down from the upper side of the inclined surface can be increased, so that the surface water can be collected. The water collecting function is improved.

In the case of overlapping rod members, it is particularly effective to lay the pile as in the sixth aspect.

According to the eighth aspect of the invention, if the side vessel is divided into the halved structure of the ground side half body and the opposite side outer half body, the half body can be overlapped and the volume can be small during transportation or storage. Therefore, it is easier to transport or keep.

Further, when the side vessel and the water collection tube are provided, as shown in the tenth aspect, after the water collection tube is inserted into the ground plate in advance, the end portion of the water collection tube can be connected to the side vessel and fixed. Since the semi-circular ground side half body is fixed during the fixing operation, the fixed water collecting pipe portion is opened, so that it can be fixed by a simple fixing mechanism, and the workability is good.

Further, the present invention is not limited to the embodiments described below. Further, in the drawings of the following embodiments, for the sake of convenience of the drawings, the dimensional relationship (proportional relationship between size, distance, and the like) of each portion does not necessarily coincide with the explanation.

(First embodiment)

Fig. 1 is a schematic plan view showing a slope of a drainage structure of a sloped ground according to a first embodiment, wherein Fig. 2(a) is an enlarged cross-sectional view taken along line AA of Fig. 1, (b) is a BB sectional view of (a), and Fig. 3 is a sectional view. The CC enlarged cross-sectional view showing the detailed structure of the CC cross section of Fig. 1 is enlarged, and Fig. 4 is a plan view of Fig. 3.

In the figures, reference numeral 1 denotes a sloped ground such as a soil or a cut soil. A U-shaped main vein drainage groove (main vein drainage path) 2 extending in a longitudinal direction of the inclined surface (in the direction of the ground surface 1a of the inclined surface disk 1 and in the upper and lower direction of FIG. 1) is provided on the surface 1a of the inclined surface ground 1 Further, a side vessel 3 connected to the main vein drain groove 2 is provided in a state in which the main vein drain groove 2 has a descending slope from a slope (horizontal direction in FIG. 1).

The lower portion of the slope of the main vein drain groove 2 is connected to, for example, a drain passage (not shown).

The lateral vessel 3 is provided in such a manner that approximately half (approximately semicircular portion) is buried in the ground as shown in FIG. The end portion of the side of the main vessel drain groove 2 of the side vessel 3 is connected to the main vein drain groove in a state of being fitted to the semicircular notch portion 2a formed in the main vein drain groove 2 as shown in Fig. 2(b). 2.

As shown in Fig. 3, an end portion on the surface side of the water collection tube 4 inserted into the ground plate is connected to the side vessel 3. The water collecting pipe 4 is a permeable water for introducing into the ground disk and sent to the side vascular tube 3, and has a plurality of water collecting holes 4a on the outer peripheral surface. The water collecting hole 4a may not be disposed in the water collecting pipe 4 Near the lower end of the section, and near the top and side sections.

In the illustrated example, the water collecting pipe 4 is disposed in the ground from the inclined surface (ground surface) in a horizontally upward direction, and is connected to the side vessel 3 as a slope toward the side vessel 3 with a plurality of descending slopes. However, it can also be connected horizontally.

The connection portion between the side vessel 3 and the water collection tube 4 is formed by inserting the end portion of the water collection tube 4 in the hole 3a of the side vessel 3, and fixing the end portion of the water collection tube 4 by the fixing mechanism 5 of the mode display. On the side of the vessel 3.

A support plate 6 is attached to the connection portion of the water collection tube 4 and the side vessel 3.

In the present embodiment, a portion of the side surface of the slanted side is formed with a concave portion (a groove extending in a direction orthogonal to the plane of the paper) as shown by a two-dotted line, and a water collecting tube is provided in the concave portion 7. 4, the ground plate is inserted, and the support plate 6 is disposed in the recess 7 so that the center hole 6a passes through the end of the water collecting pipe 4, and then the side vessel 3 is passed through the end of the connecting hole 3a through the water collecting pipe 4. The method is provided in the recessed portion 7, and the end portion of the water collection tube 4 is fixed to the side vessel 3 by the above-described fixing mechanism 5 which is schematically displayed. Thereafter, the soil sand is backfilled in the recess 7.

On the side vessel 3, a plurality of surface water collecting ports 8a which can open the ground surface 1a and collect water from the upper side of the inclined surface to collect water are provided on the upper side of the inclined surface of the radial direction. The surface water collecting port 8a of the illustrated example is formed by attaching a sleeve (short tube) 8 made of, for example, rubber, metal or plastic to the hole 3b opened in the side vessel 3.

Further, on the side vessel 3, two layers of a rod-shaped member 11 made of, for example, a thinned material or the like are stacked.

Further, on the lower side of the slope of the radial direction of the side vessel 3, a pile 12 for preventing the side vessel 3 from moving below the slope is provided. In this example, the pile 12 prevents the side vessel 3 and the rod-shaped member 11 from moving downward. Although not shown in the drawings, the rod-shaped member 11 may be wound and fixed to the pile 12 by a wire or the like.

Since the side vessel 3 protrudes from the ground surface 1a in the example of the figure, it can be blocked by the soil sand flowing down from the upper side of the slope due to the rain. Further The rod-shaped member 11 which is overlapped by two layers is made high in height, so that the amount of accumulation of soil sand (stacking depth) can be obtained. The two-point chain line S disclosed in Fig. 3 indicates the accumulated soil sand accumulated after construction.

On the inclined surface of the above-mentioned drainage structure, rainwater flows down the slope when raining, is blocked by the ground protrusion of the side vessel 3, and directly reaches the casing 8 of the side vessel 3 (surface water collection port 8a), or along The side vessel 3 of the descending slope flows to reach the cannula 8 and enters the side vessel 3 from the surface water collection port 8a, flows in the side vessel 3, and flows into the main vein drainage groove 2 in the longitudinal direction of the slope, and along the main vein. The drain tank 2 flows down, and drains to, for example, a drain passage provided at a lower portion of the slope.

Therefore, it is possible to effectively prevent the erosion of the slope caused by the surface water during rainfall. Moreover, since there is less rainwater that permeates into the interior of the site during rain, the amount of permeated water that causes the collapse of the slope can be reduced.

Moreover, after the construction, the soil sand flowing down the slope due to the rain is blocked by the side vessel 3 and is deposited on the upper side of the slope of the side vessel 3, and the accumulated soil sand S accumulated here usually also contains the humus soil or the fallen leaves. Waiting and not firmly pressing, it is a soft soil sand with more voids. Therefore, the rainwater which flows down the slope at the time of rainfall and reaches the above-mentioned accumulated soil sand S easily permeates to the lower portion (bottom portion) of the accumulated soil sand, and the casing 8 from the side vessel 3 enters the side vessel 3. The soft, accumulated soil sand is good for effectively collecting rainwater that has fallen to the slope, and achieves a higher surface water collection performance at a very low cost.

Further, the permeated water which has penetrated into the ground such as the rainwater of the inclined surface plate 1 is introduced into the water collection pipe 4 from the water collecting hole 4a of the water collecting pipe 4, and flows into the side vein along the water collecting pipe 4 of the descending slope in the illustrated example. The tube 3 flows into the main vessel drain groove 2 in the side vessel 3 of the descending gradient, and flows down the main vein drain tank 2 in the same manner as described above, and drains to the drain passage or the like at the lower portion of the slope.

In this way, since the permeated water in the site is collected by the water collecting pipe 4, the water is not drained to the surface of the ground, but is drained to the lower portion of the inclined surface via the side vessel 3 and the main vein draining groove 2, so that the inclined surface is not eroded.

According to the drainage structure, as described above, both the surface water and the permeated water of the sloped surface can be effectively excluded.

Moreover, since the drainage system of the lower portion of the sloping surface of the slanting surface of the inclined surface is performed by the side vascular tube 3 and the main vein drainage path 2 common to the surface water collecting mechanism, it is extremely effective and has good workability, and low-cost construction can be realized. . In this way, the drainage structure is effective in combining various aspects of the surface drainage work for draining the surface of the sloped surface 1 and the groundwater discharge engineering for removing the permeated water inside the ground.

Moreover, since only the main vein drain groove 2 and the side vessel 3 are covered by the slope, the area covered by the slope is narrow, so that sufficient vegetation growth can be performed on the slope. Further, the soil sand S deposited on the upper side portion of the slope of the side vessel 3 after the construction is usually soft soil sand including humus soil or fallen leaves, so the soil portion is particularly suitable for vegetation growth.

Further, the water collecting pipe 4 inserted into the inclined surface plate 1 functions as the reinforcing inclined surface plate 1 in the same manner as the steel bar inserted into the reinforcing earth process, but is installed in the connection portion of the water collecting pipe 4 and the side vessel 3. When the support plate 6 is provided, when the pull-out force acts on the water collecting pipe 4 due to the slip of the surface layer, the supporting force of the supporting plate 6 can further effectively exert the bending/pulling resistance of the water collecting pipe 4, thereby more effectively Prevent the small-scale collapse of the surface of the site.

Further, by fixing the end portion of the water collection tube 4 to the side vascular tube 3 by the above-described fixing mechanism 5, the side vascular tube 3 itself can function as the support plate 6.

Further, in the present embodiment, since the height of the rod-shaped member 11 is increased in two layers on the side vessel 3, the amount of accumulation of the soil sand flowing down from the upper side of the inclined surface can be increased, and the surface water can be collected. The water collection function of water is improved.

However, since the side vessel 3 is provided in a state in which about half (semi-circular portion) is buried in the soil, and has a certain height for the soil sand to be piled up, even if the rod-shaped member 11 is not overlapped, the pair can be exerted. The water collecting function of surface water collecting water.

Further, if about half (half-circular portion) of the side vessel 3 is buried in the soil, as shown in FIG. 2(b), the end portion of the side vessel 3 can be fitted into the main vein drain groove 2 Semicircular notch In the state of 2a, it is connected to the main vein drain tank 2, and it is suitable for allowing the water in the side vessel 3 to smoothly flow into the main vein drain tank 2. Moreover, even if the side vessel 3 is fitted only to the semicircular notch 2a, the main vein drain groove 2 can be stably connected. Therefore, the connection structure with the main vein drain tank 2 can be simplified, and the connection work can be simplified.

(Second embodiment)

Fig. 5 shows a second embodiment in which the slope of the slope is gentle.

In this embodiment, since the slope is gentle, the amount of soil sand is less, and the case where the pile is higher is less. Therefore, the rod-shaped member such as the thinning material is not overlapped on the side vessel 3. Further, a pile for preventing the side vessel 3 from moving to the lower side of the slope is not provided. Further, a fixing mechanism for fixing the end portion of the water collection tube 4 to the side vessel 3 is not provided. Also, no support plate is provided. The other configurations are substantially the same as those in the first embodiment, and the same portions are denoted by the same reference numerals and will not be described again.

When the slope of the slope is sufficiently gentle, since the component acting in the side vessel 3 has a small component in the downward direction of the slope, only about half (the semicircular portion) of the side vessel 3 is buried in the soil. When the contralateral vessel 3 is moved to the lower side of the slope, there is sufficient resistance, and the pile or the like for preventing the side vessel 3 from moving to the lower side of the slope can be omitted.

Further, in the illustrated example, the end portion of the water collection tube 4 is inserted into the connection hole 3a opened in the side vessel 3, and is not fixed to the side vessel 3. However, the fixing mechanism may be omitted as such depending on the situation.

However, by fixing the end portion of the water collection tube 4 to the side vessel 3, the side vessel 3 itself can function as the support plate, and the side vessel 3 can be prevented from moving toward the lower side of the slope. .

(Third embodiment)

The drainage structure of the inclined floor surface 1 shown in Fig. 6 divides the side vessel 23 into the ground side half body 23A of the connection hole 23a which is connected to the end portion on the surface side of the water collection tube 4, and the opposite side outer half body thereof. 23B bis quintile. Side vessel 23 of the illustrated example, ground side half 23A And both of the outer half bodies 23B have a cross-sectional shape of the flange 23c at both ends of the semicircular cross section, and when the flanges 23c of the both are opposed to each other and the flanges are bolted to each other, the circular cross section is formed. Lateral vessel 23.

In this case, in the state in which the lower side half of the side vessel 23, that is, the ground side half body 23A is buried in the ground, that is, the flange 23c at both ends of the ground side half body 23A is located on the ground surface 1a. Make settings under the sample. Further, the sleeve 8 whose end opening is the surface water collecting port 8a is attached to the outer half body 23B.

An example of a construction sequence in which the drainage structure of the sloped site 1 is constructed using the side vessel 23 will be described.

The position of the main vein drain groove 2, the side vessel 3, and the water collection tube 4 is set in advance on the inclined surface.

The longitudinal grooves are excavated along the position of the main vein drain groove 2 to be set, and the recesses 7 are excavated in a groove shape along the positions of the respective side vessels 3.

On each of the side vessels 23 to be provided, each of the water collection pipes 4 to be connected to the respective side vessels 23 is inserted into the ground at a predetermined insertion position.

Next, the support plate 6 is placed on the bottom hole (or wall surface) of the recessed portion 7 through the end portion of the water collection tube 4 through the center hole 6a.

Then, the ground side half body 23A is placed on the inclined surface so that the end portions on the surface side of each of the water collecting tubes 4 inserted into the ground plate enter the respective connecting holes 23a of the floor side half body 23A of the side vessel 23, respectively.

Next, the end portion of the water collection pipe 4 is fixed to the ground side half body 23A. In the illustrated example, the nut 25 formed on the outer surface of the end portion of the water collection tube 4 is screwed and fastened, for example, by a gasket 24 having a shape along the lower surface of the inner surface of the side vessel.

Next, the floor side half body 23A is covered with the sleeve 8 attached to the outer side half body 23B of the hole 23b, and the flange 23c is bolted to each other to form the side vessel 23 having a circular cross section. Thereafter, the soil sand is backfilled in the recess 7.

Next, the pile 12 is placed along the lower side of the slope of the side vessel 23.

Next, the main vein drain groove 2 is placed in the longitudinal groove which has been excavated in advance.

Next, the end portion of the side vessel 23 on the main vein drain groove 2 side is connected to the main vein drain groove 2.

Further, the side vascular tube 23 is connected to a plurality of short-length vascular tubes 23' having a short length as shown in FIG. 1, but if it is the case described above, it is directly connected to the end of the main-path drainage channel 2 The short side vessel 23" connected to the water collection pipe 4 is placed after the main vein drainage groove 2 is provided to carry the end portion to the circular notch 2a of the main vein drainage groove 2 (refer to Figs. 2(a) and (b)). Connected to the adjacent short-side vessel 23'. Since the short-side vessel 23" of the end portion is made shorter than the other short-side vessels 23', the region without the water-collecting tube 4 is narrow. Not too much problem.

The above procedure is an example, and the order can be changed as appropriate. For example, the main vein drain groove 2 can also be set first.

As described above, when the side vascular tube 23 is divided into the halved structure of the ground side half body 23A and the opposite side outer side half body 23B, the respective half bodies can be overlapped and reduced in size during transportation or storage. Therefore, it is easier to transport or keep.

As described above, when the side vessel 23 and the water collection tube 4 are provided, after the water collection tube 4 is inserted into the ground tray in advance, the end portion of the water collection tube 4 can be connected to the side vessel 23 and fixed. Since the semi-circular ground side half body 23A is fixed during the fixing operation, the portion of the fixed water collecting pipe 4 is opened, so that it can be fixed by a simple fixing mechanism formed by the washer 24 and the nut 25 as shown in FIG. Good sex.

(Fourth embodiment)

The drainage structure of the sloped land 1 shown in Fig. 7 is a case where the side vessel 23 is placed on the slope so as not to partially bury it in the soil. The side vessel 23 of the illustrated example is the same as the lateral vessel 23 of Fig. 6, and is a bisecting structure of the ground side half body 23A and the outer side half body 23B.

The other points are substantially the same as those of the third embodiment of Fig. 6. In the fourth embodiment, the sleeve 8 is attached to the floor side half body 23A. Moreover, the support plate 6 is directly placed on the inclined surface plate 1 The ground surface 1a is such that a spacer 30 of a triangular cross section is interposed in a triangular-shaped gap created between the support plate 6 and the side vessel 23. Further, the end portion of the water collection tube 4 is the same as that of Fig. 6, and the screw portion of the outer peripheral surface is screwed and fixed by screwing the nut 25 through the gasket 24.

Other points are substantially the same as those of the third embodiment of Fig. 6 .

In the fourth embodiment, since the side vessel 23 is placed on the ground surface, the ground protrusion height is high. Therefore, the amount of soil sand which may accumulate on the upper side of the slope of the side vessel 3 after construction can be increased.

In this case, the rod-shaped member 11 which is superposed on the side vessel 23 is two layers in the illustrated example, but may be one layer or omitted.

Fig. 8 is a view schematically showing various patterns of the arrangement of the main vein drain groove 2 and the side vein tube 3, wherein (a) is the pattern described in Fig. 1, and (b) to (f) show different arrangement patterns. In Fig. 8, although the contralateral vessel is denoted by reference numeral 3, the lateral vessel 23 of Figs. 6 and 7 is also included.

(b) The simplest pattern in which the main vein drainage groove 2 is provided with one side vessel 3 on one side thereof, and the pattern is basic.

(c) A pattern in which the main vein drain groove 2 is provided with two side vessels 3 on one side thereof.

(d) A pattern in which the main vein drainage grooves 2 are provided with two side vessels 3 on both sides thereof.

(e) A pattern in which the two side vessels 3 connected at different points of the main vein drain groove 2 are provided on both sides of the main vein drain groove 2, respectively.

(f) is a pattern in which the branch vessel 3' facing the lower side of the slope is connected to each of the side vessels 3 in the pattern of (d). On the branch side vessel 3', similar to the side vessel 3, the water collecting tube 4 inserted into the ground is connected.

In each of the above embodiments, for example, as shown in Fig. 3, one or a half of the side vascular tubes 3 protrude from the ground surface 1a, but the surface water sump 8a may be introduced to the extent that rainwater flowing down the slope is introduced. Further, when either the surface water collecting port 8a is used as the hole 3b or the surface water collecting port 8a is used as the sleeve 8, the soil sand or the like can flow in without being clogged. In this manner, a clogging prevention member such as a filter is provided on the hole 3b or the sleeve 8.

Further, in each of the above embodiments, the main vein drainage path which is inclined in the longitudinal direction is the main vein drainage channel 2, that is, the groove-shaped main vein drainage path, but may be a tubular main vein drainage path. In the case of the groove shape (main vein drain groove 2), a steel groove such as a U-shaped water tank including a corrugated steel plate, a concrete groove such as a U-shaped side groove of a precast concrete, or a resin groove may be used. In the case of a tubular main vein drainage road, a steel pipe such as a bellows or a resin pipe or a concrete pipe may be used.

As the side vessel, a steel pipe such as a bellows or a resin pipe can be used.
