Description

本発明は、シールドトンネルのセグメントリングの内側に設けられる二次覆工に用いる管材と、これを用いたシールドトンネルの二次覆工方法に関する。   The present invention relates to a pipe material used for secondary lining provided inside a segment ring of a shield tunnel, and a secondary lining method of a shield tunnel using the same.

シールドトンネルの二次覆工の工法として、コンクリートによって覆工する代わりにＦＲＰＭ管などの管材を用いる工法が知られている。
このような管材を用いる工法によれば、工事費用の削減や工期の短縮ができ、また、耐久性やトンネル内面の平滑性を向上できるので、特に下水道や農業用水路などの水路トンネルで利用されている（例えば非特許文献１参照）。
ＦＷ−Ｌ工法（シールド二次覆工）、「平成１５年１１月１０日検索」、＜http://www.asofoam.co.jp/gijyutsu.html#3＞ As a secondary lining method for a shield tunnel, a method using a pipe material such as an FRPM pipe instead of lining with concrete is known.
According to such a construction method using pipe materials, construction costs can be reduced and the construction period can be shortened, and durability and smoothness of the inner surface of the tunnel can be improved, so it is used particularly in waterway tunnels such as sewers and agricultural waterways. (For example, refer nonpatent literature 1).
FW-L method (shield secondary lining), “November 10, 2003 search”, <http://www.asofoam.co.jp/gijyutsu.html#3>

管材をトンネルの二次覆工材として用いる場合、その管材の厚さは、セグメントリングからの漏水を想定して、地下水圧に耐えうる厚さとしている。
しかし、近年の地下の輻輳化から、トンネルが深部に設置される事が多くなり、これに伴い地下水圧が高くなるため、管材の厚さを厚くする必要があり、コストが高くなっていた。 When a pipe is used as a secondary lining material for a tunnel, the thickness of the pipe is assumed to be sufficient to withstand underground water pressure, assuming water leakage from the segment ring.
However, due to the recent underground congestion, tunnels are often installed deeper, and the groundwater pressure increases accordingly. Therefore, it is necessary to increase the thickness of the pipe material, which increases the cost.

本発明の課題は、管材を用いたトンネルの二次覆工方法において、管材にかかる地下水圧を低減し、地下水圧の高い場所でも管材の厚さを厚くすることなく埋設できるようにすることである。   An object of the present invention is to reduce the underground water pressure applied to the pipe material in the secondary lining method of the tunnel using the pipe material, so that it can be embedded without increasing the thickness of the pipe material even in a place where the underground water pressure is high. is there.

以上の課題を解決するため、請求項１に記載の発明は、例えば、図１に示すように、シールドトンネルのセグメントリング４の内側に設ける二次覆工に用いる管材１であって、
前記セグメントリング４の内側に漏出した地下水を、前記管材１の内側に排水する排水手段５を、前記管材１の周面に備えることを特徴とする。 In order to solve the above problems, the invention described in claim 1 is, for example, as shown in FIG. 1, a pipe material 1 used for a secondary lining provided inside a segment ring 4 of a shield tunnel,
A drainage means 5 for draining groundwater leaked inside the segment ring 4 to the inside of the pipe 1 is provided on the peripheral surface of the pipe 1.

このように、地下水を管材１の内側に排水する排水手段５を備えることで、管材１の周囲の地下水を管材１の内側に排水でき、管材１にかかる地下水圧を低減できる。   Thus, by providing the drainage means 5 for draining the groundwater to the inside of the pipe material 1, the groundwater around the pipe material 1 can be drained to the inside of the pipe material 1, and the groundwater pressure applied to the pipe material 1 can be reduced.

請求項２に記載の発明は、請求項１に記載のシールドトンネルの二次覆工用管材であって、前記管材１はＦＲＰＭ管であることを特徴とする。   The invention according to claim 2 is the pipe material for secondary lining of the shield tunnel according to claim 1, wherein the pipe material 1 is an FRPM pipe.

このように、ＦＲＰＭ管を用いることで、管材１の重量が軽く、取り扱いが容易になる。
また、内面が滑らかで粗度係数が小さいので、同一内空断面でもコンクリートによる二次覆工に比べて管材を流れる下水等の流体の流量を多くできる。 Thus, by using the FRPM pipe, the weight of the pipe material 1 is light and the handling becomes easy.
In addition, since the inner surface is smooth and the roughness coefficient is small, the flow rate of fluid such as sewage flowing through the pipe material can be increased compared with the secondary lining by the concrete even in the same inner-air cross section.

請求項３に記載の発明は、請求項１または２に記載のシールドトンネルの二次覆工用管材であって、例えば、図２に示すように、前記排水手段５は、前記管材１の内側から外側への流れを阻止するとともに、前記管材１の外側の圧力が一定値以上のときに開いて、前記管材１の内側への排水を可能とする逆止弁６を備えることを特徴とする。   The invention described in claim 3 is the secondary lining pipe material of the shield tunnel according to claim 1 or 2, wherein, for example, as shown in FIG. And a check valve 6 that opens when the pressure on the outside of the pipe material 1 is equal to or higher than a predetermined value and allows drainage to the inside of the pipe material 1. .

このように、逆止弁６が管材１の内側から外側への流れを阻止するとともに、前記管材１の外側の圧力が一定値以上のときに開くことで、管材１の内側を流れる下水等の流体を管材１の外側に流出させることなく、管材１の外側の地下水を管材１の内側に排水できる。   In this way, the check valve 6 prevents the flow from the inside to the outside of the pipe 1 and opens when the pressure outside the pipe 1 is equal to or higher than a certain value, so that the sewage etc. flowing inside the pipe 1 The groundwater outside the pipe 1 can be drained inside the pipe 1 without causing the fluid to flow outside the pipe 1.

請求項４に記載の発明は、請求項１から３の何れか一項に記載の管材を用いたシールドトンネルの二次覆工方法であって、例えば、図１に示すように、前記管材１の外周面に導水層２を設ける第一の工程と、
前記セグメントリング４の内側に前記管材１を敷設する第二の工程と、
前記導水層２と前記セグメントリング４の間に中込材を充填し、前記管材を前記セグメントリング４の内側に固定する第三の工程とからなることを特徴とする。 Invention of Claim 4 is the secondary lining method of the shield tunnel using the pipe material as described in any one of Claim 1 to 3, Comprising: For example, as shown in FIG. A first step of providing the water guide layer 2 on the outer peripheral surface of
A second step of laying the pipe material 1 inside the segment ring 4;
It is characterized by comprising a third step of filling an intermediate material between the water guide layer 2 and the segment ring 4 and fixing the pipe material inside the segment ring 4.

このような工程によりシールドトンネルの二次覆工を行うことで、セグメントリング４の内側に漏水した地下水を管材１の内側に排水でき、管材１にかかる地下水圧を低減できるので、地下水圧の高い場所でも管材１の厚さを厚くすることなく埋設できる。
また、導水層２を管材１の外周面に設けたことで、管材１の外周面にある地下水を排水手段５に導けると共に、管材１の外周面にかかる地下水圧が均一になる。 By performing the secondary lining of the shield tunnel by such a process, the groundwater leaked inside the segment ring 4 can be drained inside the pipe 1 and the groundwater pressure applied to the pipe 1 can be reduced, so the groundwater pressure is high. It can be embeded in the place without increasing the thickness of the pipe material 1.
Further, by providing the water guide layer 2 on the outer peripheral surface of the pipe material 1, the groundwater on the outer peripheral surface of the pipe material 1 can be guided to the drainage means 5 and the groundwater pressure applied to the outer peripheral surface of the pipe material 1 becomes uniform.

請求項１に記載の発明によれば、地下水を管材の内側に排水でき、管材にかかる地下水圧を低減できる。   According to invention of Claim 1, groundwater can be drained inside a pipe material and the groundwater pressure concerning a pipe material can be reduced.

請求項２に記載の発明によれば、管材が軽量で取り扱いが容易になるとともに、内面が滑らかなので、管材内を流れる下水等の流体の流量を多くできる。   According to the second aspect of the present invention, the pipe material is light and easy to handle, and the inner surface is smooth, so that the flow rate of fluid such as sewage flowing through the pipe material can be increased.

以下、図を参照して本発明を実施するための最良の形態を詳細に説明する。
図１に示すように、この管材１は、シールドトンネルの二次覆工に用いられるもので、セグメントリング４の内部に敷設され、下水道などの流路として用いるものである。
この管材１としては、ＦＲＰＭ管（強化プラスチック複合管）を用いている。 Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, this pipe 1 is used for secondary lining of a shield tunnel, and is laid inside a segment ring 4 and used as a flow path for sewers and the like.
As the pipe material 1, an FRPM pipe (reinforced plastic composite pipe) is used.

管材１の周面には、排水手段５が管材１の長手方向に沿って適当な間隔をおいて設けられている。
この排水手段５は、図２に示すように、導水孔７と逆止弁６から構成されており、セグメントリング４の内側に漏出した地下水を管材１の外側から内側に排水するものである。 On the peripheral surface of the tube material 1, drainage means 5 is provided at an appropriate interval along the longitudinal direction of the tube material 1.
As shown in FIG. 2, the drainage means 5 is composed of a water guide hole 7 and a check valve 6, and drains groundwater leaked inside the segment ring 4 from the outside to the inside of the pipe material 1.

導水孔７は管材１の周面にあってその外側から内側に貫通する孔であり、この導水孔７を通って管材１の外周面に設けられる導水層２にある地下水が、管材１の内側に排水される。
管材１には、この導水孔７を覆うように逆止弁６が取り付けられている。
この逆止弁６は、円形の弁体９と、弁体９の中心に接続する弁軸１０とからなり、管材１の内側から外側への流体の流れを阻止するとともに、前記管材１の外側の圧力が一定値以上のときに開いて、前記管材１の内側への排水を可能とするものである。
弁体９はゴム等の弾性体からなり、その大きさは管材１に取り付けたときに、前述の導水孔７を完全に覆うことができる大きさである。
この弁体９の中心部分には、逆止弁６を管材１に固定するための弁軸１０の一端が接続されている。
また、この弁軸１０のもう一方の端部には、雄ねじが形成されていている。 The water guide hole 7 is a hole penetrating from the outside to the inside of the peripheral surface of the pipe material 1, and groundwater in the water guide layer 2 provided on the outer peripheral surface of the pipe material 1 through the water guide hole 7 is connected to the inside of the pipe material 1. To be drained.
A check valve 6 is attached to the pipe 1 so as to cover the water guide hole 7.
The check valve 6 includes a circular valve body 9 and a valve shaft 10 connected to the center of the valve body 9. The check valve 6 prevents the flow of fluid from the inside to the outside of the pipe 1 and the outside of the pipe 1. Is opened when the pressure is equal to or greater than a certain value, allowing drainage to the inside of the pipe 1.
The valve body 9 is made of an elastic body such as rubber, and the size of the valve body 9 is a size that can completely cover the water guide hole 7 when the valve body 9 is attached to the pipe member 1.
One end of a valve shaft 10 for fixing the check valve 6 to the pipe material 1 is connected to the central portion of the valve body 9.
A male screw is formed at the other end of the valve shaft 10.

逆止弁６は、弁体９が管材１の内側に配されるように、弁軸１０を逆止弁取付孔８に挿入し、管材１の外側から弁軸１０の端部にナット１１取り付け、これを締め付けることにより管材１に固定する。
このとき、弁体９の周縁部はその弾性によって管材１の内壁に密着し、管材１の外側と内側との間における流体の流れ遮断する。
この弁体９は、その弾性力と管材１内を流れる流体の圧力によって、常時管材１の内壁に密着し、導水孔７を閉鎖しているが、管材１の外側の圧力が、その圧力以上になると、弁体９の周縁部が持ち上げられ、地下水が管材内に流入するようになっている。 In the check valve 6, the valve shaft 10 is inserted into the check valve mounting hole 8 so that the valve body 9 is arranged inside the tube material 1, and a nut 11 is attached to the end of the valve shaft 10 from the outside of the tube material 1. The tube 1 is fixed by tightening it.
At this time, the peripheral portion of the valve body 9 is in close contact with the inner wall of the tube material 1 due to its elasticity, and the flow of fluid between the outside and inside of the tube material 1 is blocked.
The valve body 9 is always in close contact with the inner wall of the pipe material 1 and closes the water introduction hole 7 by its elastic force and the pressure of the fluid flowing in the pipe material 1, but the pressure outside the pipe material 1 is higher than the pressure. Then, the peripheral part of the valve body 9 is lifted, and groundwater flows into the pipe material.

この管材１の外周面には、不織布からなる導水層２が設けられており、この導水層２によって管材１の外側の地下水を排水手段５に導く。
この導水層２は、管材１の外周面の全面に設けられていて、これにより地下水を管材１の周方向および長手方向に沿って導けるようになり、管材１の外側にかかる地下水圧が均一になる。
また、一部の排水手段５が故障した場合でも、他の排水手段５に地下水を導き排水できる。 A water guide layer 2 made of a nonwoven fabric is provided on the outer peripheral surface of the tube material 1, and the ground water outside the tube material 1 is guided to the drainage means 5 by the water guide layer 2.
The water guide layer 2 is provided on the entire outer peripheral surface of the pipe material 1, thereby allowing groundwater to be guided along the circumferential direction and the longitudinal direction of the pipe material 1, and the groundwater pressure applied to the outside of the pipe material 1 is uniform. Become.
Moreover, even when some drainage means 5 breaks down, groundwater can be guided to other drainage means 5 and drained.

図１に示すように、導水層２の外側には、中込材としてエアモルタル３が充填されており、これによって、管材１はセグメントリング４の内側の略中央に固定されている。   As shown in FIG. 1, the outer side of the water guide layer 2 is filled with air mortar 3 as an intermediate material, whereby the tube material 1 is fixed to the approximate center inside the segment ring 4.

次に、以上のように構成されるシールドトンネルの二次覆工の施工方法について説明する。
なお、すでにシールドマシンによりトンネルが掘削され、その内周にセグメントリング４が形成されているものとする。 Next, the construction method of the secondary lining of the shield tunnel comprised as mentioned above is demonstrated.
It is assumed that the tunnel has already been excavated by the shield machine and the segment ring 4 is formed on the inner periphery thereof.

管材１には、シールドトンネルに搬入する前に、その外周面に不織布を貼り付け導水層２を設ける。
また、管材１は、シールドトンネルへの搬入や、施工の状況に合わせて適当な長さの物を用いる。
導水層２を設けた管材１は、シールドトンネルに搬入され、セグメントリング４の内側に敷設される。
このとき、適当な支持部材を用いて管材１を外側から支持し、管材１をセグメントリング４の内側の略中央に配すると共に、隣接する管材１との接合作業を行う。 The pipe material 1 is provided with a water guide layer 2 by adhering a non-woven fabric to the outer peripheral surface thereof before being carried into the shield tunnel.
Moreover, the pipe material 1 uses the thing of suitable length according to the condition of carrying in to a shield tunnel, or construction.
The pipe material 1 provided with the water guide layer 2 is carried into a shield tunnel and laid inside the segment ring 4.
At this time, the tube material 1 is supported from the outside by using an appropriate support member, and the tube material 1 is arranged at the approximate center inside the segment ring 4 and is joined to the adjacent tube material 1.

敷設した管材１とセグメントリング４の内側との間にエアモルタル３を充填し、管材１を固定する。
以降、上記の工程を繰り返してセグメントリング４の内側に管路を形成する。 Air mortar 3 is filled between the laid pipe 1 and the inside of the segment ring 4 to fix the pipe 1.
Thereafter, the above process is repeated to form a pipe line inside the segment ring 4.

次に、以上のように施工された二次覆工における地下水の排水方法について説明する。
セグメントリング４の内側に漏出した地下水は、エアモルタル層３に浸透し、導水層２に達する。
エアモルタル３自体の透水性はそれほど高くはないが、地下水はエアモルタル層３にできた割れ目などの空隙にそって移動し、導水層２に達する。 Next, a method for draining groundwater in the secondary lining constructed as described above will be described.
The groundwater leaking inside the segment ring 4 penetrates into the air mortar layer 3 and reaches the water conduction layer 2.
The water permeability of the air mortar 3 itself is not so high, but the groundwater moves along a gap such as a crack formed in the air mortar layer 3 and reaches the water guide layer 2.

導水層２に達した地下水は、排水手段５によって管材１の内側に排水されることとなる。
図２に示すように、逆止弁６の弁体９の周縁部は、通常、その弾性力や管材１を流れる流体の圧力等により管材１の内壁に押し付けられ、内壁に密着した状態になっている。
導水層２の地下水圧がこの圧力より大きくなったとき、弁体９の周縁部が管材１の内壁から持ち上げられ、地下水が管材１の内側に排水される。
排水によって導水層２の地下水圧が低下すると、逆止弁６の弁体９の周縁部が再び管材１の内壁に密着するようになって導水孔７が閉じる。
このように、逆止弁６は、その弾性力や管材１を流れる流体等による圧力以上の、ある一定の地下水圧を境に開閉するので、管材１内の流体が管材１の外側へ漏出することはない。 The groundwater that reaches the water guide layer 2 is drained to the inside of the pipe member 1 by the drainage means 5.
As shown in FIG. 2, the peripheral portion of the valve body 9 of the check valve 6 is normally pressed against the inner wall of the tube material 1 by its elastic force, the pressure of the fluid flowing through the tube material 1, etc., and is in close contact with the inner wall. ing.
When the groundwater pressure of the water guide layer 2 becomes higher than this pressure, the peripheral edge of the valve body 9 is lifted from the inner wall of the pipe 1, and the groundwater is drained inside the pipe 1.
When the groundwater pressure of the water guide layer 2 is lowered by drainage, the peripheral edge of the valve body 9 of the check valve 6 comes into close contact with the inner wall of the pipe material 1 and the water guide hole 7 is closed.
In this way, the check valve 6 opens and closes at a certain groundwater pressure that is higher than the elastic force and the pressure of the fluid flowing through the tube 1, so that the fluid in the tube 1 leaks outside the tube 1. There is nothing.

逆止弁６は、上記のように一定の圧力がかかると弁が開き排水を行うが、このときの圧力は管材１にかかる地下水圧の最大圧力と略等しい。
つまり、管材１の強度は、逆止弁６が動作開始する圧力に十分耐えられる強度があればよく、高い地下水圧がかかるような場所でも、管材１の厚さを厚くすることなく埋設できる。 The check valve 6 opens and drains when a constant pressure is applied as described above, and the pressure at this time is substantially equal to the maximum groundwater pressure applied to the pipe 1.
That is, the strength of the pipe material 1 is sufficient if it can sufficiently withstand the pressure at which the check valve 6 starts to operate, and it can be embedded without increasing the thickness of the pipe material 1 even in a place where high groundwater pressure is applied.

なお、近年の止水シール材の発達により、セグメント継手部分からの漏水量は多くないことから、排水手段５によって管材１の内側へ排水される地下水の量は少なく、水路としての管の機能が損なわれることはない。   In addition, since the amount of water leakage from the segment joint portion is not large due to the recent development of the water-stop seal material, the amount of groundwater drained to the inside of the pipe material 1 by the drainage means 5 is small, and the function of the pipe as a water channel is It will not be damaged.

以上の実施の形態においては、導水層２の構成として、不織布を用いるとしたが、本発明はこれに限定されるものではなく、他の素材または構造としても良い。
例えば、合成樹脂を多孔質に形成したシート状の部材や、一定粒径の骨材を合成樹脂によって結合させた成型体でも良い。
あるいは、管材１の外周面に溝を設けたり、単に管材１の周囲に空間を設けたりして、導水できるようにしても良い。
また、排水手段５の構成、配置等も任意であり、その他、具体的な細部構造等についても適宜に変更可能であることは勿論である。 In the above embodiment, although the nonwoven fabric was used as a structure of the water conveyance layer 2, this invention is not limited to this, It is good also as another raw material or structure.
For example, a sheet-like member in which a synthetic resin is formed in a porous shape, or a molded body in which an aggregate having a certain particle diameter is bonded with a synthetic resin may be used.
Alternatively, a groove may be provided on the outer peripheral surface of the tube material 1 or a space may be simply provided around the tube material 1 so that water can be introduced.
Further, the configuration, arrangement, and the like of the drainage means 5 are arbitrary, and it is needless to say that other specific detailed structures can be appropriately changed.
