Description

本発明は、地中に埋設して使用される管体であって、例えば、ドレンパイプと呼ばれる土壌改良用の集水パイプの先端部に連結して使用されるヘッド部材に関するものである。また上記用途のみならず、ボーリングに用いる管のヘッド部材として利用することも可能である。   The present invention relates to a head member that is used by being buried in the ground, for example, connected to the tip of a water collecting pipe for soil improvement called a drain pipe. Moreover, it can be used not only for the above applications but also as a head member of a pipe used for boring.

この種の地中埋設管には、例えば、図１において符号５で示したように、硬質合成樹脂製の補強線材を所定の間隔を隔てて螺旋状に巻回形成させ、この補強線材の外周面上に、合成樹脂製の薄い延伸フィルム材で形成した織布と不織布とを積層形成した集水用膜状布を集水壁として巻き付け、前記補強線材の上に別の補強線材を巻き付け、前記集水用膜状布を挟み込んで一体化したパイプが例示される。   In this kind of underground pipe, for example, as indicated by reference numeral 5 in FIG. 1, a hard synthetic resin reinforcing wire is spirally formed at a predetermined interval, and the outer periphery of the reinforcing wire is formed. On the surface, a water collecting membrane cloth formed by laminating a woven fabric and a nonwoven fabric formed of a thin stretched film material made of synthetic resin is wound as a water collecting wall, and another reinforcing wire is wound on the reinforcing wire. A pipe integrated with the water collecting membrane cloth interposed therebetween is exemplified.

他方、このような集水壁を備えた螺旋補強パイプを地中埋設管として地中に挿入させるには、パイプの先端開口部を閉塞する必要があり、かつ、この先端部を損傷させないように保護する手段が必要である。それ故先行技術では、図８に示したように、ドレンパイプＰの先端に取り付ける筒体０１を、外周面に螺旋溝０１３を備えた円筒体とし、その底部から下方に向かって突出体０１１を突出させてあるものとし、アンカー部材０２を、側面視Ｖ字形に曲げ加工した鉄板製の部材とし底板上面からも上方に向かって金属板０２１を突出させてあるものとし、これらの突出体０１１と金属板０２１とを連結させてある構造としたものであって、この構造も本出願人によって既に開発され公知となっている。
特開２００２−３８４６０号公報 特開２００２−８１０４９号公報 On the other hand, in order to insert a spiral reinforced pipe having such a water collecting wall into the ground as a buried underground pipe, it is necessary to close the tip opening of the pipe and not to damage the tip. A means of protection is needed. Therefore, in the prior art, as shown in FIG. 8, the cylindrical body 01 attached to the tip of the drain pipe P is a cylindrical body having a spiral groove 013 on the outer peripheral surface, and the protruding body 011 is formed downward from the bottom thereof. It is assumed that the anchor member 02 is an iron plate member bent into a V-shape when viewed from the side, and the metal plate 021 is protruded upward from the upper surface of the bottom plate. The metal plate 021 is connected to the structure, and this structure has already been developed and publicly known by the applicant.

しかしながら、上記のヘッド部材０１，０２は、パイプを地中に敷設する際に、パイプに対しヘッド部材が連結解除方向に相対回転することを阻止する手段を講じていなかった。つまり、パイプに対してヘッド部材が連結解除方向に相対回転することにより、パイプとヘッド部材が連結されている状態が解除されてしまい、この結果、パイプの地中への埋設が良好にできなくなる可能性が残るものであった。   However, the head members 01 and 02 do not take means for preventing the head member from rotating relative to the pipe in the connection release direction when the pipe is laid in the ground. That is, when the head member rotates relative to the pipe in the connection release direction, the state where the pipe and the head member are connected is released, and as a result, the pipe cannot be embedded in the ground well. The possibility remained.

本発明は、このような構造としたヘッド部材０１，０２が有していた課題に着目し、パイプに対しヘッド部材が相対回転してもパイプからヘッド部材が外れることなく、パイプを地中へ良好に埋設できるヘッド部材をここに提供しようとするものである。   The present invention pays attention to the problems that the head members 01 and 02 having such a structure have, and even if the head member rotates relative to the pipe, the head member does not come off from the pipe, and the pipe is brought into the ground. A head member that can be embedded satisfactorily is provided here.

該目的を達成するために講じた本発明にいうところの地中埋設管用ヘッド部材の構成を、実施例において使用した符号を用いて説明すると、埋設管の先端に取り付けて用いるヘッド部材であって、埋設管５の先端内に挿入連結させるキャップ１と、該キャップ１の先端側に連結させるアンカー部材２と、これらのキャップ１とアンカー部材２とを連結する連結部材３とからなり、前記埋設管５が、所定の間隔を隔てて螺旋巻きされた補強線材５１と、この隣り合う補強線材５１，５１間に掛け渡された、微細な無数の集水孔５４を有する集水壁５２とを備え、かつ該補強線材５１が、集水壁面からパイプの内面側に向かって突出する突条部５３を備えている構造とされ、前記キャップ１が、筒状の周壁１１と、その先端側に連設された底壁１２と、周壁１１の外周面において螺旋状に連設形成された線状部材４とを備え、
該線状部材４が弾性を備えていて、その螺旋ピッチが、前記埋設管５における補強線材５１の螺旋ピッチと略同ピッチに形成され、その上端側部分４１がキャップ１の外周面に直接または間接的に固着され、他の部分が非固着状態とされ、少なくともその下端側部分４３か途中部分４２が前記埋設管５における集水壁５２の内周径よりも外周に突出する大径部分を備えた形状に形成されている構成としたものである。 The structure of the underground pipe head member according to the present invention taken to achieve the object will be described using the reference numerals used in the examples. The head member is used by being attached to the tip of the buried pipe. The cap 1 is inserted into and connected to the tip of the buried pipe 5, the anchor member 2 is connected to the tip of the cap 1, and the connecting member 3 is connected to the cap 1 and the anchor member 2, and the buried A reinforcing wire 51 in which the pipe 5 is spirally wound at a predetermined interval, and a water collecting wall 52 having an infinite number of fine water collecting holes 54 spanned between the adjacent reinforcing wires 51, 51. And the reinforcing wire 51 includes a protrusion 53 that protrudes from the water collecting wall surface toward the inner surface of the pipe, and the cap 1 is formed on the cylindrical peripheral wall 11 and the tip side thereof. Bottom wall 1 When, and a linear member 4 which is continuously provided spirally formed in the outer peripheral surface of the peripheral wall 11,
The linear member 4 has elasticity, and its helical pitch is formed to be substantially the same as the helical pitch of the reinforcing wire 51 in the buried pipe 5, and its upper end side portion 41 is directly or directly on the outer peripheral surface of the cap 1. A large-diameter portion that is fixed indirectly and the other portion is in a non-fixed state, and at least the lower end side portion 43 or the middle portion 42 protrudes to the outer periphery from the inner peripheral diameter of the water collecting wall 52 in the buried pipe 5. It is set as the structure currently formed in the provided shape.

以上のように、本発明にいうところの地中埋設管用ヘッド部材は、キャップが周壁の外周面に、螺旋状に連設された弾性を有する線状部材を備えているものとし、この線状部材を、その上端側部分のみを固着し、他の部分を非固着状態とし、少なくともその下端側部分か途中部分が、無負荷状態で、地中埋設管における集水壁の内周径よりも外周に突出する大径部分を備えた形状としてあるので、埋設管の一端開口部内にキャップを挿入するに際して、埋設管の開口に対しキャップを単に回転させながら挿入するという単純な操作で、線状部材における外方突出状態の大径部分をパイプの集水壁に案内させながら小径化、即ち、パイプ集水壁の内周面に接触する形状に小径化させながら挿入することとなり、このようにして、一旦パイプの端部内に挿入させたキャップは何等の他の操作をも必要とすることなく、線状部材のパイプ集水壁への接触圧によって、逆回転が阻止され挿入位置に保持されることとなる。したがって、埋設管へのキャップの取付を、ほぼワンタッチ状に極めて迅速簡単に行うことができるという顕著な効果を有する。   As described above, in the underground pipe head member according to the present invention, the cap is provided with a linear member having elasticity continuously provided in a spiral manner on the outer peripheral surface of the peripheral wall. Only the upper end side part of the member is fixed and the other part is not fixed, and at least the lower end side part or the middle part is in an unloaded state and is larger than the inner peripheral diameter of the water collecting wall in the underground pipe. Since it has a shape with a large-diameter part protruding to the outer periphery, when inserting the cap into the opening of one end of the buried pipe, it is linear by simply inserting the cap while rotating it relative to the opening of the buried pipe. The large-diameter portion of the member that protrudes outwardly is reduced in diameter while being guided to the water collecting wall of the pipe, that is, inserted in a shape that makes contact with the inner peripheral surface of the pipe water collecting wall. Once the end of the pipe Without also require other operations What such cap is inserted within, the contact pressure to the pipe collecting waterwall of the linear member, so that the reverse rotation is held in the blocking insertion position. Therefore, there is a remarkable effect that the attachment of the cap to the buried pipe can be performed very quickly and easily in a substantially one-touch manner.

殊に、このようにしてパイプの端部に取り付けられたキャップは、埋設管の運搬時や地中への打ち込みに際しても、抜け落ちたり抜け出したりする不都合がなく使用することができ、地中埋設管の地中への打ち込み操作を安全にできるという利点がある。   In particular, the cap attached to the end of the pipe in this way can be used without inconvenience of falling out or coming out when the buried pipe is transported or driven into the ground. There is an advantage that the driving operation into the ground can be made safe.

また、請求項３に記載のように、アンカー部材を平板状のものとした場合には、該アンカー部材のキャップへの連結作業を広い空間内で容易にできるという効果がある。更に、請求項４に記載のように、アンカー部材をキャップに対して相対回転自在に連結させておいた場合には、地中埋設管の地中への打ち込み時に、アンカー部材が何らかの回転力を受けた場合であっても、回転力がキャップを経て埋設管に伝達しないようにして、管の破損や変形等の問題を有意に抑制できる効果がある。また、仮に若干の回転力がキャップに伝達された場合でも、キャップに設けられている線状部材が管内壁へ接当してキャップと埋設管の相対回転を抑止するので、埋設管からキャップが脱落しないようにできる効果もある。これら２点の相乗効果により、埋設管を最良の状態で敷設でき、しかも、安全に施工できる利点がある。   Further, as described in claim 3, when the anchor member has a flat plate shape, there is an effect that it is possible to easily connect the anchor member to the cap in a wide space. Furthermore, when the anchor member is connected to the cap so as to be rotatable relative to the cap as described in claim 4, the anchor member exerts some rotational force when the underground tube is driven into the ground. Even if it is received, there is an effect that the rotational force is not transmitted to the buried pipe through the cap, and problems such as breakage and deformation of the pipe can be significantly suppressed. Even if a slight rotational force is transmitted to the cap, the linear member provided on the cap abuts against the inner wall of the pipe and prevents relative rotation between the cap and the buried pipe. There is also an effect that prevents it from falling off. By these two synergistic effects, there is an advantage that the buried pipe can be laid in the best condition and can be constructed safely.

上記のような構成とした地中埋設管用ヘッド部材を実施するに当たっては、前記キャップ１を、その全体を合成樹脂素材で成形してあるものとし、前記アンカー部材２は、その全体を合成樹脂素材による成形品のほか、例えば鋼材のような鉄系金属で形成することができる。また、線状部材４も、硬質合成樹脂素材のほかステンレス線材のような金属素材で形成することができる。   In carrying out the underground pipe head member configured as described above, the cap 1 is entirely formed of a synthetic resin material, and the anchor member 2 is entirely formed of a synthetic resin material. In addition to the molded product according to the above, it can be formed of a ferrous metal such as steel. The linear member 4 can also be formed of a metal material such as a stainless steel wire in addition to a hard synthetic resin material.

以下本発明の実施例について図面に基づいて説明する。図１乃至図５は、本発明の第１実施例を示す図であって、図１は地中埋設管への取り付け状態を示す一部破断図、図２はキャップとアンカー部材との正面図、図３は同部材の平面図、図４は埋設管へのヘッド部材の取り付け手段を説明する一部破断正面図、図５は埋設管へのヘッド部材の取り付け状態を説明する平面図である。   Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 5 are views showing a first embodiment of the present invention, in which FIG. 1 is a partially broken view showing a state of attachment to an underground pipe, and FIG. 2 is a front view of a cap and an anchor member. 3 is a plan view of the same member, FIG. 4 is a partially broken front view for explaining the means for attaching the head member to the buried pipe, and FIG. 5 is a plan view for explaining the state of attachment of the head member to the buried pipe. .

該実施例に示した地中埋設管用ヘッドは、図１に示したように埋設管５の先端に取り付けて、該パイプ５に先行して地中に圧入させる先端治具である。そして、この治具は、該埋設管５の先端内部に挿入させるキャップ１の部分と、このキャップ１の先端側に連結して使用するアンカー部材２と、これらを連結する連結部材３と、キャップ１の外周に設けられた線状部材４とによって構成されている。   The underground pipe head shown in this embodiment is a tip jig that is attached to the tip of the buried pipe 5 and press-fitted into the ground prior to the pipe 5 as shown in FIG. The jig includes a portion of the cap 1 to be inserted into the tip end of the buried pipe 5, an anchor member 2 used by being connected to the tip side of the cap 1, a connecting member 3 for connecting them, and a cap. 1 and the linear member 4 provided on the outer periphery.

而して、このヘッド部材を取り付けて使用する埋設管５は、図１に示したように、パイプの内面側に向かって突出する突条部５３を備えた硬質合成樹脂製の第１の補強線材を所定の間隔を隔てて螺旋状に巻回形成させ、この補強線材の外周面上に、合成樹脂製の薄い延伸フィルム材で形成した織布と不織布とを積層形成して微細な無数の集水孔５４を備えた集水用膜状布を巻き付けて集水壁５２とし、この膜状布を押し付けるように、前記第１の補強線材の上に別の（第２の）補強線材を巻き付け、前記集水用膜状布を挟み込んで一体化すると同時に、補強線材も内外一体化して一つの補強線材５１としたものである。   Thus, the buried pipe 5 to which the head member is attached is used as shown in FIG. 1 in the first reinforcement made of a hard synthetic resin provided with a protrusion 53 protruding toward the inner surface side of the pipe. A wire material is spirally wound at a predetermined interval, and a woven fabric and a nonwoven fabric made of a thin stretched film material made of synthetic resin are laminated on the outer peripheral surface of the reinforcing wire material to form a myriad of fine shapes. A water collecting membrane cloth provided with water collecting holes 54 is wound around to form a water collecting wall 52, and another (second) reinforcing wire is placed on the first reinforcing wire so as to press the membrane cloth. At the same time as winding and sandwiching the water collecting membrane cloth, the reinforcing wire is integrated inside and outside to form one reinforcing wire 51.

前記キャップ１は、地中にあっても経時劣化が少なく、環境問題を引き起こすことのない非塩素系樹脂素材であるポリエチレン樹脂で全体を、円筒状の周壁１１と底壁１２とを有する有底円筒状に一体的に成形した単一体であって、その底壁１２の中央には、アンカー部材２を連結するための小孔を形成してある。   The cap 1 has a bottomed bottom having a cylindrical peripheral wall 11 and a bottom wall 12 entirely made of polyethylene resin, which is a non-chlorine resin material that hardly deteriorates with time even in the ground and does not cause environmental problems. A single body integrally formed in a cylindrical shape, and a small hole for connecting the anchor member 2 is formed in the center of the bottom wall 12.

また、該キャップ１の周壁１１の外周面には、同様に、ポリエチレン樹脂で形成した線状部材４を連設してある。この線状部材４は、弾性を備えていて、その螺旋ピッチを、前記埋設管５における補強線材５１の螺旋ピッチと略同じピッチに形成してあり、その上端側部分４１のみをキャップ周壁１１の外周面１３に突出形成させた第１の突起４ａ近傍のキャップ周壁上面に樹脂溶着手段または接着剤を用いて固着させてある。そして他の部分は、固着されていず、遊端状態としてある。また、外圧の作用しない平常状態では、図３に示したように平面視形状において、その途中部分（図３において上方部分）４２が、周壁１１から大きく突出する形状としてある。即ち、この途中部分４２を、前記埋設管５における集水壁５２の内周径よりも外周に突出するように大径形状としてある。なお、図中
の符号４ａ〜４ｃは、線状部材４の螺旋姿勢を支持するための第１〜第３の突起である。これらの突起４ａ〜４ｃはキャップ１の管軸方向への直線的な自由移動を阻止するための抜け止め部材として機能するものでもある。 Similarly, a linear member 4 formed of polyethylene resin is connected to the outer peripheral surface of the peripheral wall 11 of the cap 1. The linear member 4 has elasticity, and its helical pitch is formed to be substantially the same as the helical pitch of the reinforcing wire 51 in the buried pipe 5, and only the upper end side portion 41 of the cap peripheral wall 11 is formed. It is fixed to the upper surface of the cap peripheral wall in the vicinity of the first protrusion 4a formed to protrude from the outer peripheral surface 13 using a resin welding means or an adhesive. The other parts are not fixed and are in a free end state. Further, in a normal state where no external pressure acts, as shown in FIG. 3, in the plan view shape, an intermediate portion (upper portion in FIG. 3) 42 has a shape that largely protrudes from the peripheral wall 11. That is, the middle portion 42 has a large-diameter shape so as to protrude to the outer periphery from the inner peripheral diameter of the water collecting wall 52 in the buried pipe 5. Reference numerals 4 a to 4 c in the drawing are first to third protrusions for supporting the spiral posture of the linear member 4. These protrusions 4a to 4c also function as retaining members for preventing the linear free movement of the cap 1 in the tube axis direction.

前記アンカー部材２は、その全体を平板状の鋼板によって略円形状に形成したものであって、その中央部には、キャップとの連結用の小孔を穿ってある。また、平面形状を真円形状とすることなく、図３のように、この実施例では、略Ｚ字形としてある。   The anchor member 2 is formed in a substantially circular shape by a flat steel plate, and has a small hole for connection with a cap at the center. In addition, in this embodiment, the planar shape is substantially Z-shaped as shown in FIG.

このような構造としたキャップ１とアンカー部材２とを連結するには、これら両部材にそれぞれ穿設形成した前記小孔を利用して、図２，３に明らかなように、ボルト３１とナット３２からなる連結部材３を用いて上下方向に連結する。   In order to connect the cap 1 and the anchor member 2 having such a structure, as shown in FIGS. 2 and 3, the bolts 31 and the nuts are used by utilizing the small holes formed in both the members. It connects in the up-down direction using the connection member 3 which consists of 32.

このようにしたヘッド部材を埋設管５に対して取り付けるには、埋設管５の一端開口部内にキャップ１を回転させながら挿入することにより、線状部材４における外方突出状態の大径部分を埋設管５の集水壁５２に接触案内させて小径化させながら挿入すればよい。このようにして、一旦パイプの端部内に挿入させたキャップ１は、線状部材４のパイプ集水壁５２との接触圧によって逆回転が阻止されることとなって、挿入位置に保持される。   In order to attach the head member thus constructed to the buried pipe 5, the cap 1 is inserted into the opening of the one end of the buried pipe 5 while being rotated, so that the large-diameter portion of the linear member 4 in the outward projecting state is removed. What is necessary is just to insert while making it contact-guide to the water collection wall 52 of the buried pipe 5, and making it diameter-reduced. Thus, once the cap 1 is inserted into the end portion of the pipe, the reverse rotation is prevented by the contact pressure with the pipe water collecting wall 52 of the linear member 4, and the cap 1 is held at the insertion position. .

前記埋設管５の径や補強線材５１のピッチ等については必要に応じて適宜に実施されるものであって、一定形のものとする必要性はない。   The diameter of the buried pipe 5, the pitch of the reinforcing wire 51, and the like are appropriately implemented as necessary, and do not need to be a fixed shape.

図６及び図７は第２実施例について示したものであって、キャップ１に取り付けた線状部材４の平面視形状を、図６にみられるように、上端側固定部分４１から次第にキャップ１から遠ざかる渦巻き状に形成してあるものとし、即ち、末端部分４３に至るほど大径となるように形成し、埋設管５の集水壁５２を損傷させないように、最末端部分を少し内径側に曲げてある形状としたものである。その他の点については、前記第１実施例の説明に準ずる構造としてある。   6 and 7 show the second embodiment, and the shape of the linear member 4 attached to the cap 1 in plan view is gradually changed from the upper end side fixed portion 41 to the cap 1 as seen in FIG. It is assumed that it is formed in a spiral shape that is far from the end portion, that is, it is formed so as to have a large diameter as far as the end portion 43, and the outermost end portion is slightly on the inner diameter side so as not to damage the water collecting wall 52 of the buried pipe 5 It is made into the shape bent in. About another point, it is set as the structure according to description of the said 1st Example.

以上本発明の代表的と思われる実施例について説明したが、本発明は必ずしもこれらの実施例構造のみに限定されるものではなく、本発明にいうところの前記構成要件を備え、かつ、本発明にいう目的を達成し、前記の効果を有する範囲内において適宜改変して実施することができるものである。   Although the embodiments considered to be representative of the present invention have been described above, the present invention is not necessarily limited to the structures of these embodiments, and includes the above-described constituent features according to the present invention. The above-described object can be achieved, and can be implemented with appropriate modifications within the range having the above-described effects.
