〔産業上と利用分野〕
本考案は漏水箇所の発見の容易な止水構造に関
する。[Detailed description of the invention] [Industrial and field of application] The present invention relates to a water stop structure that allows easy detection of water leakage points.
第３図に示すように、地中に円筒状のコンクリ

囲に渡つて配設し、背面部からの漏水を抑える。
As shown in Figure 3, when constructing a cylindrical concrete wall underground, a method is adopted in which the total depth is divided into several stages, and concrete is poured and solidified in order from the upper stage. At this time, water stop material is placed around the entire periphery of the joints between the concrete of adjacent tiers to prevent water from leaking from the back.

ｇ−ｈ−ｉ−ａのように止水材１を配設する。 That is, as shown in FIG. 2, a-b-c-d-e-f-
The water stop material 1 is arranged like ghia.
しかしながら、この場合に、Ｗの箇所で漏水が
起きると、浸入水は接合面の止水材内側部分全体
に拡散浸透してしまい、広範な部分から内部に漏
水が起きる。したがつて、漏水箇所の発見、特定
が難しく、修理に手間取るという問題点があつ
た。 However, in this case, if water leaks at the location W, the infiltrated water will diffuse and permeate the entire inner part of the water stop material on the joint surface, causing water to leak inside from a wide area. Therefore, there was a problem in that it was difficult to discover and identify the water leakage point, and it took time to repair it.
本考案はこの問題点を改善するもので、本考案
の止水構造は、円筒状コンクリート構造物打継部

The present invention aims to improve this problem, and the water-stopping structure of the present invention is a water-stopping structure in which a water-stopping material is continuously disposed on the joint surface of a cylindrical concrete structure joint. It is characterized in that the water-stopping material is arranged so that the joint surface inside the provided water-stopping material is divided into a plurality of water-stopping sections.
本考案の止水材は、コンクリート接合面用止水
材であればいかなるものでもよいが、特に水膨潤
性物質からなる水膨潤性止水材が好ましい。 The water-stop material of the present invention may be any water-stop material for concrete joint surfaces, but water-swellable water-stop materials made of water-swellable substances are particularly preferred.
そのような水膨潤性物質として適当なものは、
例えばビニル系、アクリル系の単一重合体、もし
くは共重合体、ポリウレタン系重合体、セルロー
ス、デンプン、またはその変性物、架橋物などが
挙げられる。なかでも好ましいものは、水膨潤性
ポリウレタン含有可撓性物質であり、特に好まし
いものは、水膨潤性ポリウレタンと天然ゴム、合
成ゴム、もしくは再生ゴム等の混合物からなる可
撓性物質である。 Suitable water-swellable substances include:
Examples include vinyl-based or acrylic-based homopolymers or copolymers, polyurethane-based polymers, cellulose, starch, or modified or crosslinked products thereof. Among these, preferred are flexible materials containing water-swellable polyurethane, and particularly preferred are flexible materials comprising a mixture of water-swellable polyurethane and natural rubber, synthetic rubber, recycled rubber, or the like.
本考案の止水構造の１実施例を第１図に示す。 An embodiment of the water-stopping structure of the present invention is shown in FIG.
コンクリート構造物２の接合面に、止水材１

る。 Water stop material 1 on the joint surface of concrete structure 2
are arranged as a-b-c-d-e-f-g-h-i-a, and the same waterproof material is arranged as a-a', b-b',
..., i-i', to protect the inside of the water-stopping structure.
It is divided into water-stop sections a'-b', b'-c', ...i'-a'.
第１図において、点Ｗで漏水が起きた場合、浸

水材ａ−a′，ｂ−b′に遮られて他の止水区画には
浸透しない。よつて内側への漏水は止水区画a′−
b′のみに起こり、漏水箇所の発見、特定が大変容
易である。 In Fig. 1, when a water leak occurs at point W, the seepage water diffuses into the water-stopping section a'-b', but is blocked by the water-stopping materials a-a' and bb' and goes elsewhere. It does not penetrate into the water-tight compartment. Therefore, water leakage to the inside is blocked by the water stop section a′−
This occurs only in b', and it is very easy to find and identify the leakage point.
なお、このような止水区画の数と大きさは、工
事の目的と状況により適当に設計することがで
き、上記の態様に限られるものではない。 The number and size of such water-stopping sections can be appropriately designed depending on the purpose and situation of the construction work, and are not limited to the above embodiments.
このように、本考案の止水構造によれば、漏水
