Most water leaks in existing tunnels occur from concrete cracks or joints, or from segment joints if segments are used. There are various ways in which water leaks; if it is for a small period of time, it may become clogged naturally, but if it is for a certain amount of time, it will not become clogged, and if it is under pressure, the amount of water leaking will be enormous and at the same time. The force of the water is also intense, and the electricity bill for drainage increases. Also,
Groundwater contains various ions, and when it is discharged onto the ground or into seawater, it may change color due to air oxidation, which requires treatment. In addition, if there is water leakage, the surface of the structure will become extremely contaminated, and in the case of commercial lines, it may cause an overhead line accident.
このような事から、現在では、これらの漏水を
導水する補修工法がとられている。漏水箇所は、
水にぬれているため、コーキングや接着は難かし
く、耐久性に乏しい。 For this reason, repair methods are currently being used to channel these leaks. The location of the water leak is
Because it is wet with water, it is difficult to caulk or glue, and it is not durable.
現在は、第５図に示すような種類の補修工法が

で、漏水量を減少する効果はない。 Currently, the type of repair method shown in Figure 5 is often used. Figure 5 is a cross-sectional view of the joint, where 1 and 1' are the concrete structure, 2 is the ground,
7 represents a water pipe. All of these methods are referred to as joint water diversion, which simply directs leaking water through the joints, and do not have the effect of reducing the amount of water leakage.
本発明に係わる止水工法の特徴の一つは、金属
製の芯を有する水膨潤性止水材を目地内に打込む
ことにある。
One of the features of the water stop construction method according to the present invention is that a water-swellable water stop material having a metal core is driven into the joint.
上記水膨潤性止水材とは、水膨潤性ポリウレタ
ンと天然ゴム、合成ゴムもしくは再生ゴムの混合
物からなる水膨潤性ポリウレタン含有可撓性物質
である。 The water-swellable water stop material is a flexible material containing water-swellable polyurethane, which is a mixture of water-swellable polyurethane and natural rubber, synthetic rubber, or recycled rubber.
また、金属製の芯としては、鉄棒、鉄線などが
使用できる。 Further, as the metal core, an iron rod, an iron wire, etc. can be used.
以下、図面を参照して、本発明工法を説明す
る。 Hereinafter, the construction method of the present invention will be explained with reference to the drawings.
本発明では、第１図に示すように、金属製芯部
３ａを有する水膨潤性止水材３を、コンクリート
構造物１，１′の間の目地に打込むことを基本的

通であるが、水膨潤性止水材３は、水との接触に
よつて膨潤し、漏水が生じるようなすきまを埋め
てしまうのである。 The basic feature of the present invention is that, as shown in FIG. 1, a water-swellable water stop material 3 having a metal core 3a is cast into the joint between concrete structures 1 and 1'. This effectively prevents water from leaking from the ground 2. In other words, such joints are generally very uneven and the width is not constant, but the water-swellable water-stopping material 3 swells when it comes into contact with water and fills gaps where water leaks may occur. It is.
水膨潤性止水材３内に存在する金属製芯３ａ

軸方向の膨張を規制し、水膨潤性物質のタレを防
止する。 Metal core 3a present in water-swellable water stop material 3
adds strength to the water-stopping material, restricts expansion of the water-stopping material in the axial direction, and prevents the water-swellable substance from dripping.
本発明の止水工法の第一は、上記手段による漏
水防止をさらに確実にするために金属製の芯を有
する水膨潤性止水材と、これを固定するための固
定金具をともに目地内に打ち込むものである。 The first method of the present invention is to install a water-swellable water-stopping material having a metal core and a fixing fitting for fixing it in the joint in order to further ensure the prevention of water leakage by the above-mentioned means. It's something you put into it.
第２図は、本発明の第一の止水工法を示すもの
で、目地内に打込まれた水膨潤性止水材３が固定
金具４によつて固定され、水膨潤性物質の前面へ
のタレ及び腹出しが確実に防止される。 FIG. 2 shows the first water-stopping method of the present invention, in which the water-swellable water-stop material 3 inserted into the joint is fixed by a fixing fitting 4, and the water-swellable material 3 is fixed to the front surface of the water-swellable material. The sauce and spillage are reliably prevented.
固定金具４としては変形が容易である鉛管鉛棒
等がよい。 The fixing fitting 4 is preferably a lead pipe or lead rod that can be easily deformed.
さらに、長期に渡つて確実に目地からの漏水を
防止するためには、裏込剤の注入をする必要があ

に適用され、金属製の芯を有する水膨潤性止水
材、又は金属製の芯を有する水膨潤性止水材とこ
れを固定するための固定金具を目地に打ち込み、
次いで裏込材を目地内奥部に注入することを特徴
とする。 Furthermore, in order to reliably prevent water leakage from joints over a long period of time, it is necessary to inject a backfilling agent. A water-swellable water-stopping material with a metal core or a water-swellable water-stopping material with a metal core and a fixing fitting for fixing it are driven into the joint,
The method is characterized in that a backing material is then injected deep into the joint.

好ましくない。したがつて、コンクリートや鉄部
材との接着性の良い、ポリマーセメント系、アス
フアルト乳材系のモルタルとか、ウレタン系の注
入材が良い。 As a backing material, ordinary air mortar and other mortars do not adhere well to concrete and do not follow the vibrations of the tunnel.
Undesirable. Therefore, it is better to use polymer cement-based mortar, asphalt-based mortar, or urethane-based injection material, which have good adhesion to concrete and steel parts.
第３図は、本発明の第二の止水工法を示すもの
で、目地内に打込まれた水膨潤性止水材３の末端
部より、裏込材５が注入され、背面地山２からの
漏水を確実に防止するものである。 FIG. 3 shows the second water-stopping construction method of the present invention, in which a backing material 5 is injected from the end of the water-swellable water-stopping material 3 that has been cast into the joint, and the backing material 5 is injected into the back ground 2. This is to reliably prevent water leakage.

特徴とする。 The third water-stopping method of the present invention is to more completely prevent water leakage, and uses a water-swellable water-stopping material with a metal core, or a water-swellable water-stopping material with a metal core. This method is characterized by driving a fixing metal fitting into the joint, then injecting a backing material deep into the joint, and then applying a surface coating material to the joint without removing or removing the fixing metal fitting.
第４図はこの第三の止水工法を示すもので、
