【考案の詳細な説明】
本考案は砂防ダム、コンクリート貯水槽、貯水
ダム等漏水問題を有するコンクリート構造物に関
するものである。[Detailed Description of the Invention] The present invention relates to concrete structures having water leakage problems, such as erosion control dams, concrete water tanks, and water storage dams.
昔に施工した砂防ダムが最近ではコンクリート
のクラツク、又は工法が悪くてコンクリート打継
ぎ目の隙間等による漏水が問題になつている。こ
のための防水工法として
(イ) コンクリートを前面に新しく打継ぐ、
(ロ) コンクリート注入する
等の方法が考えられているが、前者は工事費が高
く、又クラツクの心配がある、後者はうまくいか
ない。 Recently, erosion control dams that were constructed in the past have become problematic due to concrete cracks or water leakage due to poor construction methods, such as gaps between concrete pouring joints. Possible waterproofing methods for this purpose include (a) pouring new concrete on the front, and (b) pouring concrete, but the former is expensive and has the risk of cracking, while the latter does not work. .
上記に鑑み本考案は簡易確実に前記漏水問題を
解決したものである。以下例示図面に就いて本考
案を詳細に説明する、ただしこれだけに限定され
るものではない。 In view of the above, the present invention solves the water leakage problem simply and reliably. The present invention will be described in detail below with reference to the illustrative drawings, but the present invention is not limited thereto.
さて第１図に一般的な砂防ダムの正面図を例示
した。この砂防ダムの止水面に本考案の防水工法
を施したものの断面は第２図の如くである。 Figure 1 shows an example of the front view of a typical erosion control dam. The cross-section of this sabo dam with the water-stopping surface applied with the waterproofing method of the present invention is shown in Figure 2.
本考案に於いてはダム本体１の６面側即ち上流
水側にゴム又はゴム引布の防水シート３を貼付け
防水工法をする。 In the present invention, a waterproofing method is used in which a waterproof sheet 3 made of rubber or rubberized cloth is pasted on six sides of the dam body 1, that is, on the upstream water side.
しかし乍ら防水シートのみを貼付けた場合
流木等により、上流水が越流する頂点部の防
水シートが損傷を受ける。 However, if only a waterproof sheet is attached, the waterproof sheet at the top where upstream water overflows will be damaged by driftwood, etc.
堆積した土砂圧と水圧等により防水シートが
損傷を受ける。 The tarpaulin sheet is damaged by the accumulated soil pressure and water pressure.
等の問題点が考えられる。この対策として、防水
シートとコンクリートの間にクツシヨン２を設
け、流木や堆積した土砂、水圧により、防水シー
トが破損することを防止する。Possible problems include: As a countermeasure against this problem, a cushion 2 is provided between the waterproof sheet and the concrete to prevent the waterproof sheet from being damaged by driftwood, accumulated earth and sand, and water pressure.
なおシートの下部及び上部は第２図に示すよう
に４と５のコンクリートにて固定する。 The lower and upper parts of the seat are fixed with concrete 4 and 5 as shown in Figure 2.
以上の様な本考案によると下記のような利点が
ある。 The present invention as described above has the following advantages.
越流する流木等流下物に対し、シート下にク
ツシヨンを設けているので、これがシートを保
護する、即ちシートの損傷を防ぐことができ
る。 Since a cushion is provided under the seat from overflowing objects such as driftwood, this can protect the seat, that is, prevent damage to the seat.
ダムの上流側の水、土砂に接する面にシート
下にクツシヨンを設けているので、このクツシ
ヨン効果により旧ダムのコンクリート面が荒れ
ていて凹凸になつていても仕上げる必要なく直
接施工することができ石や砂圧等によるシート
の損傷をも防止できる。 A cushion is installed under the sheet on the upstream side of the dam, which is in contact with water and soil, so even if the concrete surface of the old dam is rough and uneven, it can be directly constructed without the need for finishing. It can also prevent damage to the sheet due to stones, sand pressure, etc.
コンクリート工事量が減り施工が簡単であ
る。従つて工費が安く工期も短かい。 The amount of concrete work is reduced and construction is easy. Therefore, the construction cost is low and the construction period is short.
