Description
【０００１】[0001]
本考案は、地山又は一次覆工の表面に二次覆工を打設する前に、建設されるト ンネルに防水機能を付与するために、前記地山又は一次覆工の表面に防水シ−ト を取付けるための防水シ−ト取付構造に関するものである。 In order to impart a waterproof function to the tunnel to be constructed before placing the secondary lining on the surface of the natural ground or the primary lining, the present invention provides a waterproof seal on the surface of the natural ground or the primary lining. -The present invention relates to a waterproof sheet mounting structure for mounting a sheet.
【０００２】[0002]
トンネルの建設に際しては、出来上がったトンネルが堅牢であることは勿論、 防水性に富んだものであることが望まれる。その理由は、防水性がないと、トン ネル上の地山から水がトンネル内に滲出，滴下するし、冬期、特に寒冷地におい ては、前記のトンネル内に滲出した水が凍って氷柱となり、トンネル上壁から垂 下して事故の原因になるばかりでなく、トンネル自体が凍結して歪が生じ、この 歪は解凍しても全部は復元しないで残留するため、長年月の間には損壊するおそ れがあるからである。 When constructing a tunnel, it is desirable that the finished tunnel is not only robust, but also highly waterproof. The reason is that if it is not waterproof, water will seep and drip into the tunnel from the ground on the tunnel, and in winter, especially in cold regions, the water that seeps into the tunnel will freeze and become icicles. Not only does it cause an accident by hanging down from the top wall of the tunnel, but the tunnel itself freezes and causes distortion. Even if the distortion is thawed, the whole remains without being restored. This is because it can be damaged.
【０００３】 そのため、従来、ア−チ状に掘削したトンネルの表面又は該表面上に形成した 一時覆工の表面に防水シ−トを取付けるための構造については、数多くの提案が なされている。例えば、実開昭64-10599号公報に記載された考案がある。この考 案における防水シ−トの取付構造は、図５に示すように、面ファスナの雄側部材 のように外面に多数の係止用突起F1を形成した金属製，合成樹脂製等の帯状又は 面状をなす支持部材Ｆを前記係止用突起F1をトンネル内空側に向けトンネルのコ ンクリ−ト壁面Ｇ又は地山に線状，又は点状に取付ける一方、裏面に不織布等を 部分的に貼着して成る被係止層A1を形成した防水シ−トＡを、その被係止層A1を 前記支持部材Ｆの係止用突起F1に押圧係止させる構造である。Therefore, conventionally, many proposals have been made on a structure for attaching a waterproof sheet to the surface of a tunnel excavated in an arch shape or the surface of a temporary lining formed on the surface. For example, there is a device described in Japanese Utility Model Laid-Open No. 64-10599. As shown in FIG. 5, the waterproof sheet mounting structure in this consideration is made of metal, synthetic resin, or the like having a large number of locking projections F 1 formed on the outer surface like the male member of the surface fastener. The support member F in the form of a strip or a surface is attached to the concrete wall surface G of the tunnel or the ground in a linear or dotted manner with the locking projection F 1 facing the inner side of the tunnel, while a nonwoven fabric or the like is attached to the back surface A structure in which a waterproof sheet A having a locked layer A 1 formed by partially adhering the above is pressed and locked by the locking layer A 1 to the locking projection F 1 of the support member F. Is.
【０００４】 然し乍ら、これでは、ア−チ状に掘削したトンネルの表面は勿論、その表面に 施工した一時覆工の表面も凹凸が多く、支持部材Ｆを同じ高さに取付けることは 困難であり、また、防水シ−トＡを貼着する場合、この防水シ−トＡは通常不透 明のため、被係止層A1を支持部材Ｆに当てがって押圧するのに、手さぐりで作業 を行わなければならないので、作業能率が極めて悪く、しかも、凹んだ部分に取 付けられた支持部材Ｆには被係止層A1を係止させることが出来ず、従って、全体 として防水シ−トＡの係止力が弱くなり、作業途中に脱落するおそれがある。However, in this case, not only the surface of the tunnel excavated in the shape of an arch but also the surface of the temporary lining constructed on the surface have many irregularities, and it is difficult to mount the supporting member F at the same height. In addition, when the waterproof sheet A is attached, since the waterproof sheet A is usually opaque, it is necessary to apply the locked layer A 1 to the supporting member F by pressing it by hand. Since the work has to be performed, the work efficiency is extremely low, and further, the locked layer A 1 cannot be locked to the support member F attached to the recessed portion, so that the waterproof seal as a whole. -The locking force of the gate A becomes weak, and it may fall off during work.
【０００５】 また、支持部材の取付に際しては、通常釘やアンカ−ボルトＢ等を用いるが、 それらの頭が支持部材の係止用突起を邪魔する結果、有効に作用する係止用突起 F1の面積が減少して被係止層A1を係止しにくくなるおそれもあるのである。Further, when mounting the support member, a nail, an anchor bolt B, or the like is usually used. However, as a result of the heads of them interfering with the locking protrusion of the support member, the locking protrusion F 1 that works effectively. There is also a possibility that the area of the area is reduced and it becomes difficult to lock the locked layer A 1 .
【０００６】[0006]
本考案は上述のような従来技術の問題点に鑑み、従来技術における支持部材と 防水シ−トの被係止層との係止関係を強固にすると共に、防水シ−トの貼着作業 を容易に施工できるトンネルの防水シ−ト取付構造を提供することを、その課題 とするものである。 In view of the problems of the prior art as described above, the present invention strengthens the locking relationship between the support member and the locked layer of the waterproof sheet in the prior art, and at the same time attaches the waterproof sheet. It is an object of the present invention to provide a waterproof sheet mounting structure for a tunnel that can be easily installed.
【０００７】[0007]
本考案は上記課題を解決することを目的としてなされたもので、その構成は、 地山をア−チ状に掘削して形成したトンネルの表面又は該トンネルの表面に形成 した一時覆工の表面に、不織布等から成り面ファスナの雄部材のような係止用突 起を多数設けた係止部材の係止用突起を強固に係止する通水緩衝材を貼着し、該 通水緩衝材の表面に、裏面に前記係止部材を適宜間隔を置いて点状に定着した防 水性シ−トを、係止部材の係止用突起を係止させて貼着するようにしたことを特 徴とするものである。 The present invention has been made for the purpose of solving the above-mentioned problems, and its structure is the surface of a tunnel formed by excavating the ground in an arch shape or the surface of a temporary lining formed on the surface of the tunnel. A water-permeable cushioning material that firmly locks the locking projections of a locking member, such as a male member of a hook-and-loop fastener, which is made of non-woven fabric and has a large number of locking projections, is attached to the On the front surface of the material, the waterproofing sheet, in which the above-mentioned locking members are fixed on the back surface at appropriate intervals and fixed in dots, is attached by locking the locking projections of the locking members. It is a special feature.
【０００８】 即ち、本考案は、ア−チ状に掘削して形成したトンネル又は該トンネルの表面 に、不織布等から成り面ファスナの雄部材のような係止用突起を多数設けた係止 部材の係止用突起を強固に絡着係止する通水緩衝材を貼着すれば、該通水緩衝材 は可撓性を有するもので、トンネル又は一時覆工の表面によく馴染んで貼着され るから、その表面に、裏面に前記係止部材をその係止用突起を外側にして点状に 定着した防水シ−トを、その係止部材を通水緩衝材に押圧して絡着係止させるこ とにより、防水シ−トは強固に通水緩衝材に貼着でき、結果として防水シ−トを 前記トンネル又はその表面に形成した一時覆工に貼着できるとの観点からなされ たものである。That is, the present invention is a tunnel member formed by excavating in an arch shape or a locking member provided with a large number of locking projections such as male members of hook and loop fasteners made of non-woven fabric on the surface of the tunnel. If a water-permeable cushioning material that firmly locks and engages the locking projections of is attached, the water-permeable cushioning material will be flexible and will adhere well to the surface of the tunnel or temporary lining. Therefore, the waterproof sheet in which the locking member is fixed to the front surface on the back surface in a dot shape with the locking projections on the outer side is pressed against the water-absorbing cushioning material and entangled. By locking it, the waterproof sheet can be firmly attached to the water-permeable cushioning material, and as a result, the waterproof sheet can be attached to the tunnel or a temporary lining formed on the surface thereof. It is a thing.
【０００９】[0009]
次に本考案の実施例を図により説明する。図１はトンネルの一時覆工の表面に 通水緩衝材を貼着した状態の一部の断面図、図２は裏面に係止部材を点状に定着 した防水シ−トの一部の断面図、図３は通水緩衝材の表面に防水シ−トを貼着し た状態の一例を示す図、図４は第３図の状態から二次覆工を施工した状態の断面 図、図５は従来技術により防水シ−トをトンネルの一時覆工の表面に貼着した状 態の一部の断面図である。 Next, an embodiment of the present invention will be described with reference to the drawings. Figure 1 is a partial cross-sectional view of the temporary lining of the tunnel with water-permeable cushioning material attached, and Figure 2 is a partial cross-section of the waterproof sheet with locking members fixed in dots on the back surface. Fig. 3 is a diagram showing an example of a state in which a waterproof sheet is attached to the surface of the water-permeable cushioning material, and Fig. 4 is a sectional view showing a state in which a secondary lining has been applied from the state of Fig. 3, 5 is a sectional view of a part of a state in which a waterproof sheet is attached to the surface of a temporary lining of a tunnel by a conventional technique.
【００１０】 図１〜図４において、１はトンネルの一次覆工、２はその表面に釘３の打ち込 み等により貼着した通水緩衝材で、不織布等の、後述する係止部材の係止用突起 をよく絡着係止できる素材により作製された可撓性のあるものであり、貼着に際 しては一次覆工１の状態に応じてランダムに施工するものとする。４は合成樹脂 製シ−トから成る防水シ−トで、その裏面に面ファスナの雄部材から成る係止部 材５を適宜間隔を置いて点状に定着してあり、この係止部材５は基板51の片面に 頭部52を茸状に形成した係止用突起53を多数設けて構成されている。In FIGS. 1 to 4, 1 is a primary lining of a tunnel, 2 is a water-permeable cushioning material that is attached to the surface of the tunnel by hammering nails 3, etc. The locking projections are made of a material that can be well entangled and locked, and are flexible at the time of sticking, depending on the state of the primary lining 1. Reference numeral 4 denotes a waterproof sheet made of a synthetic resin sheet, and locking members 5 made of male members of hook-and-loop fasteners are fixed on the back surface thereof in spots at appropriate intervals. Is configured by providing a large number of locking projections 53 each having a head 52 formed in a mushroom shape on one surface of a substrate 51.
【００１１】 而して、通水緩衝材２は可撓性があるため、これを一次覆工１に貼着すると、 該一次覆工１に凹凸があっても、図１に示すように、よく馴染んで略ア−チ状に 貼着することが出来、従って、該通水緩衝材２の表面に係止部材５を押しつける ようにして防水シ−ト４を貼着すれば、係止部材５の頭部52が通水緩衝材２内に 進入して係止用突起53が該通水緩衝材２に絡着係止され、防水シ−ト４が通水緩 衝材２から脱落することなく貼着される。尚、防水シ−ト４に透明又は半透明の ものを用いれば、その表面から係止部材５の定着部が確認できるので、その貼着 作業を容易且つ確実に行うことが出来る。Since the water-permeable cushioning material 2 is flexible, if it is attached to the primary lining 1, even if the primary lining 1 has irregularities, as shown in FIG. It can be adhered well and can be attached in a substantially arched shape. Therefore, if the waterproof sheet 4 is attached by pressing the locking member 5 against the surface of the water-permeable cushioning material 2, the locking member can be attached. The head portion 52 of the member 5 enters the water-permeable cushioning material 2, the locking projections 53 are entwined and locked to the water-permeable cushioning material 2, and the waterproof sheet 4 falls off from the water-permeable cushioning material 2. It is stuck without any. If a transparent or semi-transparent waterproof sheet 4 is used, the fixing portion of the locking member 5 can be confirmed from the surface thereof, so that the sticking work can be performed easily and reliably.
【００１２】 また、上記のようにして、貼着された通水緩衝材２及び防水シ−ト４は、貼着 後適当なたるみが生じるため、図３に示すように、一次覆工１と通水緩衝材２と の間に空隙ａがあっても、二次覆工Ｎの打設時にそれらが一次覆工１面によく馴 染み、図４に示すように、それを埋めるので、完成したトンネルは極めて堅牢な ものとなる。Further, the water-permeable cushioning material 2 and the waterproof sheet 4 attached as described above have an appropriate slack after the attachment, so that as shown in FIG. Even if there is a space a between the water-permeable cushioning material 2 and the water-permeable cushioning material 2, they fit well to the primary lining 1 surface when the secondary lining N is placed, and as shown in FIG. The tunnel will be extremely robust.
【００１３】 更に、一次覆工１に直接通水緩衝材２を貼着し、その上に防水シ−ト４を貼着 するようにしたから、両者が別々になるため、材料の軽量化を図れると共に、工 場における両者の貼り合わせ作業を行わなくてもよいので、全体としてコストの 低減を図ることが出来る。Further, since the water-permeable cushioning material 2 is directly adhered to the primary lining 1 and the waterproof sheet 4 is adhered on the water-permeable cushioning material 2, the both are separated, so that the weight of the material is reduced. At the same time, it is possible to reduce the cost as a whole because it is not necessary to carry out the bonding work of the both in the factory.
【００１４】 而して、実際の上記の貼着作業に際しては、トンネルのア−チ壁面に沿って移 動する展張機等により通水緩衝材２を展張しながら釘３を打ち込んで止める機械 を用いて通水緩衝材２を貼着した後、同様の機械を用いて防水シ−ト４を通水緩 衝材２に圧接せながら係止部材５を該通水緩衝材２に絡着係止させるようにした り、或は通水緩衝材２を貼着しながら防水シ−ト４を該通水緩衝材２の表面に貼 着する機械を用いて作業を行わせるようにすれば、施工を迅速に行うことが出来 て、施工コストの大幅な低減を図ることが出来る。In the actual pasting work, a machine for driving the nails 3 while driving the water-permeable cushioning material 2 while spreading the water-permeable cushioning material 2 by a spreading machine or the like that moves along the arch wall surface of the tunnel is used. After sticking the water-permeable cushioning material 2 by using the same, a locking machine 5 is attached to the water-permeable cushioning material 2 while pressing the waterproof sheet 4 against the water-permeable cushioning material 2 using the same machine. If the water-absorbing cushioning material 2 is attached or the waterproof sheet 4 is attached to the surface of the water-absorbing cushioning material 2, the work can be performed. The construction can be done quickly, and the construction cost can be greatly reduced.

本考案は上述の通りであるから、地山をア−チ状に掘削して形成したトンネル 又は該トンネルの表面に施工した一次覆工の表面に防水シ−トを取付けるための 構造として好適であり、建設されたトンネルの強度の向上を図ることが出来るこ とは勿論、材料面でのコストの低減、作業費用の低減等、トンネル建設のコスト を大幅に低減できる。 Since the present invention is as described above, it is suitable as a structure for attaching the waterproof sheet to the surface of the tunnel formed by excavating the ground in an arch shape or the surface of the primary lining constructed on the surface of the tunnel. Therefore, not only can the strength of the constructed tunnel be improved, but the cost of construction of the tunnel can be greatly reduced by reducing the material cost and working cost.
