自然斜面のみならず、鉄道や道路の施工に伴う盛土や切土、宅地造成地等の土砂部の斜面は、降水量が土砂部の浸透能力を超えてしまい地下水位が上昇したり土砂の含水比が高くなると崩壊してしまう場合がある。このため、土砂部内の水分を排水することで地下水位および土砂の含水比を低下させ斜面の崩落を防ぐ技術として、従来ねじ切りされた排水パイプが用いられている。 Not only natural slopes, but also slopes of earth and sand such as embankments, cuts, and residential land development sites due to the construction of railways and roads, the amount of precipitation exceeds the infiltration capacity of the earth and sand, and the groundwater level rises and the soil contains water. If the ratio is high, it may collapse. For this reason, a threaded drainage pipe has been conventionally used as a technique for reducing the groundwater level and the water content ratio of the earth and sand by draining the water in the earth and sand portion to prevent the slope from collapsing.

しかしながら、従来のねじ切りされた排水パイプは、排水パイプのねじ切りの目が極めて細かいため、排水パイプ同士を連結する際に土砂が噛んでしまう虞がある。そして、従来のねじ切りされた排水パイプは、仮に土砂が噛んでしまった場合には途中まで連結した排水パイプ同士を一度取り外して、その土砂を取り除いた上で再度排水パイプ同士を連結する必要があるため、現場で容易に連結することができず、ひいては施工コストが増大するという問題点があった。 However, in the conventional threaded drainage pipe, the threaded mesh of the drainage pipe is extremely fine, so that there is a risk that earth and sand will bite when connecting the drainage pipes to each other. Then, in the conventional threaded drainage pipe, if the earth and sand are bitten, it is necessary to remove the drainage pipes connected halfway once, remove the earth and sand, and then connect the drainage pipes again. Therefore, there is a problem that it cannot be easily connected at the site, which in turn increases the construction cost.

また、特許文献1の開示技術は、テーパおねじとテーパめねじとが管軸方向で連続して設けられることにより、排水パイプ等の斜面などの地盤に貫入する管状部材として用いられてこれらを連結する場合、テーパおねじとテーパめねじとの間で土砂が噛んでしまう虞がある。そして、特許文献1の開示技術は、仮に土砂が噛んでしまった場合には途中まで連結した管同士を一度取り外して、その土砂を取り除いた上で再度管同士を連結する必要があるため、現場で容易に連結することができず、施工コストが増大するという問題点があった。 Further, the technique disclosed in Patent Document 1 is used as a tubular member that penetrates into the ground such as a slope of a drainage pipe or the like by providing a tapered male thread and a tapered female thread continuously in the pipe axis direction. When connecting, there is a risk that earth and sand will get caught between the tapered male screw and the tapered female screw. Then, in the technique disclosed in Patent Document 1, if the earth and sand are bitten, it is necessary to remove the pipes connected halfway once, remove the earth and sand, and then connect the pipes again. There is a problem that it cannot be easily connected and the construction cost increases.

特許文献2の開示技術は、管とは別の管継手が必要なため、現場で用いる部材数が増大し、管継手を介して管状部材同士を連結するものであるため、現場で容易に連結することができず、施工コストが増大するという問題点があった。 Since the technique disclosed in Patent Document 2 requires a pipe joint different from the pipe, the number of members used in the field increases, and the tubular members are connected to each other via the pipe joint, so that the tubular members can be easily connected in the field. There was a problem that the construction cost increased because it could not be done.

さらに、特許文献1及び特許文献2の開示技術では、管状部材の内部に土砂部の水分が流れる場合、いずれも継手箇所の内周面が全周にわたってコルゲート加工されている構造上、継手箇所で堆積する土砂によって流水が阻害されるため、土砂部に蓄積された水分を効率よく排出することが困難であった。 Further, in the disclosed techniques of Patent Document 1 and Patent Document 2, when the water in the earth and sand portion flows inside the tubular member, the inner peripheral surface of the joint portion is corrugated over the entire circumference, so that the joint portion has a structure. Since the flowing water is hindered by the accumulated sediment, it is difficult to efficiently discharge the water accumulated in the sediment.

そこで本発明は、上述した問題点に鑑みて案出されたものであり、その目的とするところは、現場で管状部材を容易に連結することが可能となるとともに、排水パイプとして用いる際も排水性のよい管状部材の継手構造、管状部材及び管状部材の施工方法を提供することにある。 Therefore, the present invention has been devised in view of the above-mentioned problems, and an object of the present invention is that tubular members can be easily connected in the field and drainage is performed even when used as a drainage pipe. It is an object of the present invention to provide a joint structure of a tubular member having good properties, a tubular member, and a method of constructing the tubular member.

特に、第発明によれば、第1外面山部の管周方向の幅は、第1外面谷部の管周方向の幅よりも長く、第2内面山部の管周方向の幅は、第2内面谷部の管周方向の幅よりも長いため、第1連結部と第2連結部とを相対移動させたとしても、第1外面山部と第2内面山部が互いに案内されて連結しやすいとともに、第1連結部と第2連結部の強度を高めることが可能となる。 In particular, according to the sixth invention, the width of the first outer surface mountain portion in the pipe circumferential direction is longer than the width of the first outer surface valley portion in the pipe circumferential direction, and the width of the second inner surface mountain portion in the pipe circumferential direction is. Since it is longer than the width of the second inner surface valley portion in the pipe circumferential direction, even if the first connecting portion and the second connecting portion are relatively moved, the first outer surface mountain portion and the second inner surface mountain portion are guided to each other. In addition to being easy to connect, it is possible to increase the strength of the first connecting portion and the second connecting portion.

Further, the second inner surface valley portion 35 of the second connecting portion 30 is the inner peripheral surface 12 of the tubular member 102, and unevenness is not formed on the inner peripheral surface 12 of the tubular member 102.

このため、本発明を適用した管状部材の継手構造1は、第1連結部20と第2連結部30とが連結されるとき、仮に一方の管状部材101や他方の管状部材102に土砂Gが付着していたとしても、土砂Gが第1外面山部24や第2内面山部34等に接触しながら、第1連結部20の第1外面山部24の間に形成される第1外面谷部25及び第2連結部30の第2内面山部34の間に形成される第2内面谷部35の何れか一方又は両方を通り、他方の管状部材102の外側に土砂が移動するので、土砂が噛むことなく、一方の管状部材101と他方の管状部材102とを連結することが可能となる。 Therefore, in the joint structure 1 of the tubular member to which the present invention is applied, when the first connecting portion 20 and the second connecting portion 30 are connected, the earth and sand G is temporarily attached to one tubular member 101 and the other tubular member 102. Even if it adheres, the first outer surface formed between the first outer surface mountain portion 24 of the first connecting portion 20 while the earth and sand G is in contact with the first outer surface mountain portion 24, the second inner surface mountain portion 34, and the like. Since the earth and sand move to the outside of the other tubular member 102 through either or both of the second inner surface valley portion 35 formed between the valley portion 25 and the second inner surface mountain portion 34 of the second connecting portion 30. It is possible to connect one tubular member 101 and the other tubular member 102 without biting earth and sand.

このように本発明を適用した管状部材の継手構造1は、第1連結部20と第2連結部30とが連結されるとき、土砂Gが噛まずに互いを連結することができるため、従来のような連結途中の管状部材を一度取り外して土砂を取り除く作業を省略することができ、一方の管状部材101と他方の管状部材102とを現場で容易に連結することが可能となる。 As described above, in the joint structure 1 of the tubular member to which the present invention is applied, when the first connecting portion 20 and the second connecting portion 30 are connected, the earth and sand G can be connected to each other without biting. It is possible to omit the work of removing the tubular member in the middle of connection and removing the earth and sand, and it is possible to easily connect one tubular member 101 and the other tubular member 102 at the site.

また、本発明を適用した管状部材の継手構造1は、図8に示すように、第1外面山部24の長さL1が、第2内面山部34の離間距離L4よりも短く、第2内面山部34の長さL3が、第1外面山部24の離間距離L2よりも短くなるものである。これにより、本発明を適用した管状部材の継手構造1は、図中矢印P方向に向けて第1連結部20と第2連結部30とが相対移動できるものであり、いわば第1連結部20と第2連結部30とが管軸方向Xで遊嵌状態とされる。 Further, in the joint structure 1 of the tubular member to which the present invention is applied, as shown in FIG. 8, the length L1 of the first outer surface mountain portion 24 is shorter than the separation distance L4 of the second inner surface mountain portion 34, and the second The length L3 of the inner surface mountain portion 34 is shorter than the separation distance L2 of the first outer surface mountain portion 24. As a result, in the joint structure 1 of the tubular member to which the present invention is applied, the first connecting portion 20 and the second connecting portion 30 can move relative to each other in the direction of the arrow P in the drawing, so to speak, the first connecting portion 20. And the second connecting portion 30 are in a loosely fitted state in the pipe axis direction X.

このため、本発明を適用した管状部材の継手構造1は、第1連結部20と第2連結部30とが連結されるときに図中矢印P方向に向けて第1連結部20と第2連結部30とを1回又は複数回相対移動させることで、土砂Gが第1外面山部24や第2内面山部34等に接触しながら、第1連結部20の第1外面山部24の間に形成される第1外面谷部25及び第2連結部30の第2内面山部34の間に形成される第2内面谷部35の何れか一方又は両方を通り、他方の管状部材102の外側に土砂が移動するので、土砂が噛むことなく、一方の管状部材101と他方の管状部材102とを連結する効果を高めることが可能となる。 Therefore, in the joint structure 1 of the tubular member to which the present invention is applied, when the first connecting portion 20 and the second connecting portion 30 are connected, the first connecting portion 20 and the second connecting portion 20 and the second connecting portion 20 are directed in the direction of arrow P in the drawing. By relatively moving the connecting portion 30 once or a plurality of times, the earth and sand G comes into contact with the first outer surface mountain portion 24, the second inner surface mountain portion 34, etc., and the first outer surface mountain portion 24 of the first connecting portion 20 A tubular member that passes through either or both of the first outer surface valley portion 25 formed between the two and the second inner surface valley portion 35 formed between the second inner surface valley portions 34 of the second connecting portion 30. Since the earth and sand move to the outside of the 102, it is possible to enhance the effect of connecting the one tubular member 101 and the other tubular member 102 without the earth and sand biting.

このように本発明を適用した管状部材の継手構造1は、第1連結部20と第2連結部30とが連結されるとき、土砂Gが噛まずに互いを連結することができるため、従来のような連結途中の管状部材を一度取り外して土砂を取り除く作業を省略することができ、一方の管状部材101と他方の管状部材102とを現場で容易に連結する効果をより高めることが可能となる。 As described above, in the joint structure 1 of the tubular member to which the present invention is applied, when the first connecting portion 20 and the second connecting portion 30 are connected, the earth and sand G can be connected to each other without biting. It is possible to omit the work of removing the tubular member in the middle of connection once to remove the earth and sand, and it is possible to further enhance the effect of easily connecting the one tubular member 101 and the other tubular member 102 in the field. Become.

なお、本発明を適用した管状部材の継手構造1は、第1外面山部24の幅B1が、第2内面谷部35の幅B4よりも長く、第2内面山部34の幅B3が、第1外面谷部25の幅B2よりも長くされる。これにより、本発明を適用した管状部材の継手構造1は、図中矢印P方向に向けて第1連結部20と第2連結部30とを相対移動させたとしても、管軸方向Xで第1連結部20と第2連結部30とが脱離するのを防止することが可能となる。 In the joint structure 1 of the tubular member to which the present invention is applied, the width B1 of the first outer surface mountain portion 24 is longer than the width B4 of the second inner surface valley portion 35, and the width B3 of the second inner surface mountain portion 34 is. It is made longer than the width B2 of the first outer surface valley portion 25. As a result, in the joint structure 1 of the tubular member to which the present invention is applied, even if the first connecting portion 20 and the second connecting portion 30 are relatively moved in the direction of the arrow P in the drawing, the first connecting portion 20 and the second connecting portion 30 are moved in the pipe axis direction X. It is possible to prevent the 1 connecting portion 20 and the 2nd connecting portion 30 from being detached from each other.

本発明を適用した管状部材の継手構造1は、図9(a)に示すように、第1連結部20と第2連結部30とが相対回転されることで、第2内面山部34が第1外面山部24に嵌合されて、一方の管状部材101の端部10aに形成される傾斜部29が、他方の管状部材102の端部10bに当接された状態で、第1連結部20と第2連結部30とが連結される。 In the joint structure 1 of the tubular member to which the present invention is applied, as shown in FIG. 9A, the first connecting portion 20 and the second connecting portion 30 are relatively rotated, so that the second inner surface mountain portion 34 is formed. The first connection is made in a state where the inclined portion 29, which is fitted to the first outer surface mountain portion 24 and is formed on the end portion 10a of one tubular member 101, is in contact with the end portion 10b of the other tubular member 102. The portion 20 and the second connecting portion 30 are connected.

このとき、本発明を適用した管状部材の継手構造1は、図9(b)に示すように、第1連結部20の第1内面谷部27が、管軸方向Xに並べて配置される。第1内面谷部27は、一方の管状部材101の内周面12であり、一方の管状部材101の内周面12に対して凹凸が形成されないものとなる。このため、本発明を適用した管状部材の継手構造1は、土砂部9に蓄積された水分を排水するときに、一方の管状部材101の内部で土砂が堆積するのを抑制し、一方の管状部材101の内部から水分を効率よく排出することが可能となる。 At this time, in the joint structure 1 of the tubular member to which the present invention is applied, as shown in FIG. 9B, the first inner surface valley portion 27 of the first connecting portion 20 is arranged side by side in the pipe axis direction X. The first inner surface valley portion 27 is the inner peripheral surface 12 of one tubular member 101, and unevenness is not formed on the inner peripheral surface 12 of the one tubular member 101. Therefore, the joint structure 1 of the tubular member to which the present invention is applied suppresses the accumulation of earth and sand inside one tubular member 101 when draining the water accumulated in the earth and sand portion 9, and the other tubular member Moisture can be efficiently discharged from the inside of the member 101.

このとき、本発明を適用した管状部材の継手構造1は、一方の管状部材101から他方の管状部材102に向けて水分が排水されるのが好ましい。本発明を適用した管状部材の継手構造1は、傾斜部29が管軸方向Xに対して一定の勾配で傾斜されるものとなり、縮径部23の内部を通って水分が排水されることとなるため、一方の管状部材101の内部から他方の管状部材102の内部へ向けて水分を効率よく排出することが可能となる。逆に、本発明を適用した管状部材の継手構造1は、他方の管状部材102から一方の管状部材101に向けて水分が排水される場合には、他方の管状部材102の内部で縮径部23の近傍に土砂が堆積しやすいものとなるためである。 At this time, in the joint structure 1 of the tubular member to which the present invention is applied, it is preferable that water is drained from one tubular member 101 toward the other tubular member 102. In the joint structure 1 of the tubular member to which the present invention is applied, the inclined portion 29 is inclined with a constant gradient with respect to the pipe axis direction X, and water is drained through the inside of the reduced diameter portion 23. Therefore, it is possible to efficiently drain water from the inside of one tubular member 101 toward the inside of the other tubular member 102. On the contrary, the joint structure 1 of the tubular member to which the present invention is applied has a reduced diameter portion inside the other tubular member 102 when water is drained from the other tubular member 102 toward the one tubular member 101. This is because sediment is likely to accumulate in the vicinity of 23.

また、本発明を適用した管状部材の継手構造1は、従来のように管とは別の管継手を用いることなく、第1連結部20と第2連結部30とにより、一方の管状部材101と他方の管状部材102とを直接連結するため、容易に連結することが可能となる。 Further, in the joint structure 1 of the tubular member to which the present invention is applied, one tubular member 101 is formed by the first connecting portion 20 and the second connecting portion 30 without using a pipe joint different from the pipe as in the conventional case. And the other tubular member 102 are directly connected to each other, so that they can be easily connected.

また、本発明を適用した管状部材の継手構造1は、第1外面山部24の幅B1が、第1外面谷部25の幅B2よりも長く、第2内面山部34の幅B3が、第2内面谷部の幅B4よりも長いため、第1連結部20と第2連結部30とを相対移動させたとしても、第1外面山部24と第2内面山部34が互いに案内されて連結しやすいとともに、第1連結部20と第2連結部30の連結強度を高めることが可能となる。 Further, in the joint structure 1 of the tubular member to which the present invention is applied, the width B1 of the first outer surface mountain portion 24 is longer than the width B2 of the first outer surface valley portion 25, and the width B3 of the second inner surface mountain portion 34 is. Since it is longer than the width B4 of the second inner surface valley portion, even if the first connecting portion 20 and the second connecting portion 30 are relatively moved, the first outer surface mountain portion 24 and the second inner surface mountain portion 34 are guided to each other. It is possible to easily connect the first connecting portion 20 and to increase the connecting strength of the second connecting portion 30.

また、本発明を適用した管状部材の継手構造1は、本管部15に適宜間隔で水抜き孔19が形成されるため、土砂部9の水分を水抜き孔19を通じて集水して、排水することが可能となる。 Further, in the joint structure 1 of the tubular member to which the present invention is applied, since drainage holes 19 are formed in the main pipe portion 15 at appropriate intervals, the water in the earth and sand portion 9 is collected through the drainage holes 19 and drained. It becomes possible to do.

次に、本発明を適用した管状部材の施工方法について、説明する。 Next, a method of constructing a tubular member to which the present invention is applied will be described.

本発明を適用した管状部材の施工方法は、本管部15に適宜間隔で水抜き孔19を形成させた管状部材10を管軸方向Xで連結するための施工方法である。 The method of constructing a tubular member to which the present invention is applied is a method of constructing a tubular member 10 having drainage holes 19 formed in the main pipe portion 15 at appropriate intervals in the pipe axial direction X.

本発明を適用した管状部材の施工方法は、一方の管状部材101の端部10aに形成される第1連結部20と、他方の管状部材102の端部10bに形成される第2連結部30とを連結する連結工程を備える。 In the method of constructing a tubular member to which the present invention is applied, a first connecting portion 20 formed at an end portion 10a of one tubular member 101 and a second connecting portion 30 formed at an end portion 10b of the other tubular member 102. It is provided with a connecting process for connecting and.

連結工程では、図10に示すように、先ず、一方の管状部材101を、土砂部9の斜面91に打ち込む。このとき、連結工程では、一方の管状部材101の第1連結部20を土砂部9の斜面91から突出されるように、一方の管状部材101の第2連結部30側を土砂部9の斜面91に打ち込む。連結工程では、一方の管状部材101の管軸方向Xを水平に対して傾斜させて、第1連結部20が第2連結部30よりも下方側に配置されるようにして、一方の管状部材101を土砂部9の斜面91に打ち込む。 In the connecting step, as shown in FIG. 10, first, one of the tubular members 101 is driven into the slope 91 of the earth and sand portion 9. At this time, in the connecting step, the slope of the earth and sand portion 9 is set on the side of the second connecting portion 30 of the one tubular member 101 so that the first connecting portion 20 of one tubular member 101 protrudes from the slope 91 of the earth and sand portion 9. Type in 91. In the connecting step, the tube axial direction X of one tubular member 101 is inclined with respect to the horizontal so that the first connecting portion 20 is arranged below the second connecting portion 30, and one tubular member 101 is driven into the slope 91 of the earth and sand portion 9.

連結工程では、次に、土砂部9の斜面91に打ち込んだ一方の管状部材101を、他方の管状部材102の第2連結部30に挿通する。そして、連結工程では、図11に示すように、第1連結部20と第2連結部30とを管周方向Wに相対回転させ、第2内面山部34と第1外面山部24とを嵌合する。 In the connecting step, next, one tubular member 101 driven into the slope 91 of the earth and sand portion 9 is inserted into the second connecting portion 30 of the other tubular member 102. Then, in the connecting step, as shown in FIG. 11, the first connecting portion 20 and the second connecting portion 30 are relatively rotated in the pipe circumferential direction W, and the second inner surface mountain portion 34 and the first outer surface mountain portion 24 are connected to each other. Fit.

これにより、連結工程では、図7に示すように、一方の管状部材101や他方の管状部材102に土砂Gが付着していたとしても、土砂Gが第1外面山部24や第2内面山部34等に接触しながら、第1連結部20の第1外面山部24の間に形成される第1外面谷部25及び第2連結部30の第2内面山部34の間に形成される第2内面谷部35の何れか一方又は両方を通り、他方の管状部材102の外側に土砂が移動するので、土砂が噛むことなく、連結することが可能となる。 As a result, in the connecting step, as shown in FIG. 7, even if the earth and sand G adheres to one tubular member 101 and the other tubular member 102, the earth and sand G is attached to the first outer surface mountain portion 24 and the second inner surface mountain. It is formed between the first outer surface valley portion 25 formed between the first outer surface mountain portions 24 of the first connecting portion 20 and the second inner surface mountain portion 34 of the second connecting portion 30 while in contact with the portions 34 and the like. Since the earth and sand move to the outside of the other tubular member 102 through either or both of the second inner surface valley portion 35, the earth and sand can be connected without being bitten.

また、連結工程では、図8に示すように、図中矢印P方向に向けて第1連結部20と第2連結部30とを相対移動させてもよい。連結工程では、第1連結部20と第2連結部30とが連結するときに図中矢印P方向に向けて第1連結部20と第2連結部30とを1回又は複数回相対移動させる。これにより、連結工程では、土砂Gが第1外面山部24や第2内面山部34等に接触しながら、第1連結部20の第1外面山部24の間に形成される第1外面谷部25及び第2連結部30の第2内面山部34の間に形成される第2内面谷部35の何れか一方又は両方を通り、他方の管状部材102の外側に土砂が移動するので、土砂が噛むことなく、連結する効果を高めることが可能となる。 Further, in the connecting step, as shown in FIG. 8, the first connecting portion 20 and the second connecting portion 30 may be relatively moved in the direction of the arrow P in the drawing. In the connecting step, when the first connecting portion 20 and the second connecting portion 30 are connected, the first connecting portion 20 and the second connecting portion 30 are relatively moved once or a plurality of times in the direction of the arrow P in the drawing. .. As a result, in the connecting step, the first outer surface is formed between the first outer surface mountain portion 24 of the first connecting portion 20 while the earth and sand G is in contact with the first outer surface mountain portion 24, the second inner surface mountain portion 34, and the like. Since the earth and sand move to the outside of the other tubular member 102 through either or both of the second inner surface valley portion 35 formed between the valley portion 25 and the second inner surface mountain portion 34 of the second connecting portion 30. , It is possible to enhance the effect of connecting without biting the earth and sand.

連結工程では、図12に示すように、更に第1連結部20と第2連結部30とを管周方向Wに相対回転させ、第2内面山部34と第1外面山部24とを嵌合して、一方の管状部材101の端部10aの傾斜部29と、他方の管状部材102の端部10bとを接触させて、一方の管状部材101の第1連結部20と他方の管状部材102の第2連結部30とを連結する。 In the connecting step, as shown in FIG. 12, the first connecting portion 20 and the second connecting portion 30 are further rotated relative to the pipe circumferential direction W, and the second inner surface mountain portion 34 and the first outer surface mountain portion 24 are fitted. In addition, the inclined portion 29 of the end portion 10a of one tubular member 101 and the end portion 10b of the other tubular member 102 are brought into contact with each other, and the first connecting portion 20 of one tubular member 101 and the other tubular member are brought into contact with each other. The second connecting portion 30 of 102 is connected.

連結工程では、次に、図13に示すように、互いに連結した一方の管状部材101と他方の管状部材102とを、土砂部9の斜面9に向けて打ち込む。このとき、連結工程では、図12に示すように、第2連結部30が形成される他方の端部10bが他方の管状部材102の本管部15よりも拡径されることなく、他方の端部10bの径が本管部15の径と均一に形成されるものとなる。このため、連結工程では、土砂部9に打ち込まれる一方の管状部材101と他方の管状部材102とに作用する周面摩擦力を低減させることができ、円滑にこれらを打ち込むことが可能となる。 In the connecting step, as shown in FIG. 13, one tubular member 101 and the other tubular member 102, which are connected to each other, are then driven toward the slope 9 of the earth and sand portion 9. At this time, in the connecting step, as shown in FIG. 12, the other end portion 10b on which the second connecting portion 30 is formed is not enlarged in diameter from the main portion 15 of the other tubular member 102, and the other end portion 10b is formed. The diameter of the end portion 10b is formed to be uniform with the diameter of the main pipe portion 15. Therefore, in the connecting step, the peripheral frictional force acting on one tubular member 101 and the other tubular member 102 to be driven into the earth and sand portion 9 can be reduced, and these can be smoothly driven.

そして、連結工程では、上述した手順を所定の回数繰り返して、土砂部9の斜面91に所定の本数だけ管状部材10を打ち込んで、完了する。 Then, in the connecting step, the above-mentioned procedure is repeated a predetermined number of times, and a predetermined number of tubular members 10 are driven into the slope 91 of the earth and sand portion 9 to complete the process.

本発明を適用した管状部材の施工方法では、管状部材101における第1連結部20を管状部材101における第2連結部30よりも下方側に配置されるように、管状部材101の管軸方向Xを水平に対して傾斜させて、土砂部9の斜面91に打ち込まれる。このため、本発明を適用した管状部材の施工方法によれば、管状部材101の内部で排水される水分を外側に排出しやすくすることが可能となる。 In the method of constructing a tubular member to which the present invention is applied, the tube axial direction X of the tubular member 101 is arranged so that the first connecting portion 20 of the tubular member 101 is arranged below the second connecting portion 30 of the tubular member 101. Is inclined with respect to the horizontal, and is driven into the slope 91 of the earth and sand portion 9. Therefore, according to the method of constructing the tubular member to which the present invention is applied, it is possible to easily discharge the water drained inside the tubular member 101 to the outside.

なお、上述した本発明を適用した管状部材の施工方法では、連結工程において、図14に示すように、管状部材10の第2連結部30を土砂部9の斜面91から突出するように、管状部材10の第1連結部20側を土砂部9の斜面91に打ち込んでもよい。このとき、連結工程では、管状部材10の管軸方向Xを水平に対して傾斜させて、第2連結部30が下方側に配置されるようにして、管状部材10を土砂部9の斜面91に打ち込む。 In the method of constructing a tubular member to which the present invention is applied as described above, in the connecting step, as shown in FIG. 14, the second connecting portion 30 of the tubular member 10 is tubular so as to protrude from the slope 91 of the earth and sand portion 9. The first connecting portion 20 side of the member 10 may be driven into the slope 91 of the earth and sand portion 9. At this time, in the connecting step, the tubular member 10 is tilted with respect to the horizontal direction X so that the second connecting portion 30 is arranged on the lower side, and the tubular member 10 is placed on the slope 91 of the earth and sand portion 9. Type in.

また、図13、図14のように管状部材10を土砂部9の斜面91に打ち込むことに限らず、例えば、図15のように、土砂部9に打ち込まれる管状部材10が集水井や排水トンネル等の土中構造物99に接続されていてもよい。 Further, the tubular member 10 is not limited to being driven into the slope 91 of the earth and sand portion 9 as shown in FIGS. 13 and 14, and for example, as shown in FIG. 15, the tubular member 10 driven into the earth and sand portion 9 is a catchment well or a drainage tunnel. It may be connected to the soil structure 99 such as.

なお、本発明を適用した管状部材10は、縮径部23に第1連結部20が形成される形態について説明したが、他の実施形態によって具現化されてもよい。管状部材10は、図16(a)に示すように、本管部15と同一径で形成される一方の端部10aに第1連結部20が形成されるものであってもよい。 Although the form in which the first connecting portion 20 is formed in the diameter-reduced portion 23 of the tubular member 10 to which the present invention is applied has been described, it may be embodied by other embodiments. As shown in FIG. 16A, the tubular member 10 may have a first connecting portion 20 formed at one end portion 10a formed having the same diameter as the main portion 15.

このとき、第1連結部20は、図16(b)に示すように、管状部材10の外周面11から突出されて管周方向Wで間隔を空けて螺旋状に配置される複数の第1外面山部24と、管周方向Wで隣り合う第1外面山部24の間に形成される第1外面谷部25とを有する。 At this time, as shown in FIG. 16B, the first connecting portion 20 is a plurality of first connecting portions that are projected from the outer peripheral surface 11 of the tubular member 10 and are arranged spirally at intervals in the circumferential direction W. It has an outer surface mountain portion 24 and a first outer surface valley portion 25 formed between the first outer surface mountain portions 24 adjacent to each other in the pipe circumferential direction W.

第1連結部20は、図17(a)に示すように、エンボス加工が施されることで管状部材10の外周面11に矩形状に形成される第1外面山部24と、第1外面山部24に対向して管状部材10の内周面12に矩形状に形成される第1内面溝部26とを有するものとなる。 As shown in FIG. 17A, the first connecting portion 20 has a first outer surface mountain portion 24 formed in a rectangular shape on the outer peripheral surface 11 of the tubular member 10 by being embossed, and a first outer surface. It has a first inner surface groove portion 26 formed in a rectangular shape on the inner peripheral surface 12 of the tubular member 10 facing the mountain portion 24.
