擁壁やコンクリート水路などのコンクリート構造物には、一般的に、裏込め土中の水を排水して揚圧力を減少させるため、水抜き用の孔（「ウィープホール」と一般に呼ばれている）が設けられている。ウィープホールは典型的には、コンクリート構造物に設けた貫通孔に、パイプを通すことによって形成されている。   Concrete structures such as retaining walls and concrete channels are commonly called drain holes ("weep holes") to drain the water in the backfill soil and reduce the lifting pressure. ) Is provided. A weep hole is typically formed by passing a pipe through a through hole provided in a concrete structure.

しかしながら、設置した後数年経過すると、ウィープホールは目詰まりを起こすが、従来のウィープホールは、いわゆる“埋め殺し式”であるため、目詰まりを起こした場合であっても容易に交換することができなかった。また、ウィープホール裏面の集水材兼吸い出し防止フィルタ材等が、コンクリート構造物の背面の圧密沈下等により破壊したり脱落したりして土砂が流出する等の問題を生じていた。   However, when a few years have passed since installation, the weepholes become clogged, but the conventional weepholes are so-called “fill-in type” so that they can be easily replaced even when clogging occurs. I could not. In addition, the water collecting material and anti-suction filter material on the back side of the weep hole has been damaged or dropped off due to the consolidation settlement on the back side of the concrete structure, causing problems such as earth and sand flowing out.

Moreover, the weephole of this invention can be utilized also for a waterway or a river structure by attaching a backflow prevention valve.

次に、図面を参照して、本発明の好ましい実施の形態に係るカートリッジ式ウィープホールについて詳細に説明する。図１は、本発明の好ましい実施の形態に係るカートリッジ式ウィープホールの分解図である。図１において全体として参照符号１０で示される本発明の好ましい実施の形態に係るカートリッジ式ウィープホールは、外管１２を備えている。外管１２は、第１部分１４と、第２部分１６とによって構成されている。   Next, a cartridge type weep hole according to a preferred embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is an exploded view of a cartridge type weep hole according to a preferred embodiment of the present invention. A cartridge-type weep hole according to a preferred embodiment of the present invention, indicated generally by the reference numeral 10 in FIG. The outer tube 12 includes a first portion 14 and a second portion 16.

外管１２の第１部分１４は、両端が開放し、両端にフランジ１４ａ、１４ｂが設けられた管状部材によって形成されている。外管１２の第２部分１６は、開口した一端にフランジ１６ａが設けられ、他端が閉鎖した管状部材によって形成されている。第２部分１６の外面には、水抜き用の複数の開口部１６ｂが設けられている。第１部分１４と第２部分１６は、同じ内径を有する管状部材で形成されており、対向するフランジ１４ｂ、１６ａを当接させてボルト等の締結具１８で互いに接続されている。なお、第１部分１２の長さは、ウィープホールを取り付けようとするコンクリート壁の厚さと略等しくなるように選定されている。   The first portion 14 of the outer tube 12 is formed by a tubular member having both ends open and flanges 14a and 14b provided at both ends. The second portion 16 of the outer tube 12 is formed by a tubular member provided with a flange 16a at one open end and closed at the other end. A plurality of openings 16 b for draining water are provided on the outer surface of the second portion 16. The first portion 14 and the second portion 16 are formed of a tubular member having the same inner diameter, and are connected to each other by a fastener 18 such as a bolt with the opposing flanges 14b and 16a abutting against each other. In addition, the length of the 1st part 12 is selected so that it may become substantially equal to the thickness of the concrete wall which attaches a weep hole.

カートリッジ式ウィープホール１０は又、外管１２内に収容される内管２０を備えている。内管２０は、開口した一端にフランジ２０ａが設けられ、他端が閉鎖した管状部材によって形成されている。内管２０は、外管１２内に収容することができるように、その外径が外管１２の内径よりも僅かに小さくなるように選定されている。また、内管２０の閉鎖端の側の半部の外面に、水抜き用の複数の開口部２０ｂが設けられている。   The cartridge-type weep hole 10 also includes an inner tube 20 that is received in the outer tube 12. The inner tube 20 is formed by a tubular member provided with a flange 20a at one open end and closed at the other end. The inner tube 20 is selected so that its outer diameter is slightly smaller than the inner diameter of the outer tube 12 so that it can be accommodated in the outer tube 12. Further, a plurality of openings 20b for draining are provided on the outer surface of the half of the inner tube 20 on the closed end side.

カートリッジ式ウィープホール１０は更に、内管２０内に収容される本体２２を備えている。本体２２は、一端が開放し、他端が閉鎖した管状部材によって形成されている。本体２２は、内管２０内に収容することができるように、その外径が内管２０の内径よりも僅かに小さくなるように選定されている。また、本体２２の閉鎖端の側の半部の外面に、水抜き用の複数の開口部２２ａが設けられている。   The cartridge-type weep hole 10 further includes a main body 22 accommodated in the inner tube 20. The main body 22 is formed by a tubular member having one end opened and the other end closed. The main body 22 is selected so that its outer diameter is slightly smaller than the inner diameter of the inner pipe 20 so that it can be accommodated in the inner pipe 20. In addition, a plurality of openings 22 a for draining water are provided on the outer surface of the half portion on the closed end side of the main body 22.

好ましくは、外管１２は、鋼管で形成されており、内管２０及び本体２２は、塩化ビニル樹脂等の合成樹脂材料で形成されている。   Preferably, the outer tube 12 is formed of a steel tube, and the inner tube 20 and the main body 22 are formed of a synthetic resin material such as vinyl chloride resin.

以上のように構成されたカートリッジ式ウィープホール１０の使用について説明する。まず、第１部分１４をコンクリート構造物の型枠に取り付けた後、型枠内にコンクリートを打設する。型枠内のコンクリートが硬化した後、第１部分１４に第２部分１６を接続し、第１部分１４と第２部分１６とによって構成される外管１２内に、内管２０及び本体２２を挿入する。なお、第２部分１６の開口部１６ｂから土砂がウィープホール１０内に侵入しないように、第２部分１６の外面を土砂侵入防止ネット（図３参照）で被覆するのが好ましい。また、内管２０を外管１２に固定しようとする際、フランジ１４ａとフランジ２０ａとの間に、パッキン２４を介在させるのが好ましい（図２参照）。さらに、本体２２を内管２０内に収容する際、本体２２にＯリング２２ｂを装着するのがよい。   The use of the cartridge type weep hole 10 configured as described above will be described. First, after attaching the 1st part 14 to the formwork of a concrete structure, concrete is laid in a formwork. After the concrete in the mold is cured, the second portion 16 is connected to the first portion 14, and the inner tube 20 and the main body 22 are placed in the outer tube 12 constituted by the first portion 14 and the second portion 16. insert. In addition, it is preferable to cover the outer surface of the second portion 16 with an earth-and-sand intrusion prevention net (see FIG. 3) so that the earth and sand do not enter the weep hole 10 from the opening 16b of the second portion 16. Moreover, when trying to fix the inner pipe 20 to the outer pipe 12, it is preferable to interpose the packing 24 between the flange 14a and the flange 20a (see FIG. 2). Further, when the main body 22 is accommodated in the inner tube 20, an O-ring 22 b is preferably attached to the main body 22.

ウィープホール１０に目詰まり等が生じた場合には、外管１２に対して内管２０を回転させて、外管１２の開口部１６ｂと内管２０の開口部２０ｂが整列しないようにした後（開口部１６ｂから内管２０内に土砂が入り込まないようにするためである）、内管２０及び本体２２を引き抜き、新しいものに交換する。内管２０及び本体２２を引き抜いた際、外管１２の内部を洗浄することもできる。   When the weep hole 10 is clogged, the inner tube 20 is rotated with respect to the outer tube 12 so that the opening 16b of the outer tube 12 and the opening 20b of the inner tube 20 are not aligned. (This is to prevent earth and sand from entering the inner tube 20 from the opening 16b), and the inner tube 20 and the main body 22 are pulled out and replaced with new ones. When the inner tube 20 and the main body 22 are pulled out, the inside of the outer tube 12 can be cleaned.

本発明は、以上の発明の実施の形態に限定されることなく、特許請求の範囲に記載された発明の範囲内で、種々の変更が可能であり、それらも本発明の範囲内に包含されるものであることはいうまでもない。   The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say, it is something.

例えば、前記実施の形態においてカートリッジ式ウィープホール１０は、３つの構成部分（外管、内管、及び本体）から構成されているが、裏込め土の状況等に応じて、内管を省略して２つの構成部分（外管と本体）でカートリッジ式ウィープホールを構成してもよい。   For example, in the above-described embodiment, the cartridge type weep hole 10 is composed of three components (the outer tube, the inner tube, and the main body), but the inner tube is omitted depending on the conditions of the backfill soil. Alternatively, the cartridge type weep hole may be constituted by two constituent parts (the outer tube and the main body).

また、カートリッジ式ウィープホール１０を水路や河川構造物等に使用する場合には、図５に示されるような逆流防止弁２６をウィープホール１０に取り付けるのがよい。図５に示される逆流防止弁２６は、両端が開放した略筒状の形状を有しており、水路又は河川側の端部に開閉式の蓋２６ａが取り付けられている。蓋２６ａは、上端においてピン２６ｂでヒンジ止めされており、Ａ方向（裏込め土側）からの水流に対しては開放し（図５（ａ）において二点鎖線で図示）、Ｂ方向（水路又は河川側）からの水流に対しては閉鎖する（図５（ａ）において実線で図示）ようになっている。蓋２６ａは好ましくは、ゴムで形成されている。また、逆流防止弁２６の内面底部には、Ａ方向からの僅かな水流に対しても対応することができるように、溝２６ｃが設けられている。   Further, when the cartridge type weep hole 10 is used for a water channel or a river structure, a backflow prevention valve 26 as shown in FIG. 5 is preferably attached to the weep hole 10. The backflow prevention valve 26 shown in FIG. 5 has a substantially cylindrical shape with both ends open, and an openable / closable lid 26a is attached to the end of the waterway or river. The lid 26a is hinged at the upper end with a pin 26b, and is open to the water flow from the A direction (backfill soil side) (shown by a two-dot chain line in FIG. 5A), and in the B direction (water channel). Alternatively, the water flow from the river side is closed (illustrated by a solid line in FIG. 5A). The lid 26a is preferably made of rubber. Further, a groove 26c is provided at the bottom of the inner surface of the backflow prevention valve 26 so as to cope with a slight water flow from the A direction.
