【発明の詳細な説明】 産業上の利用分野 本発明は、築堤のために基礎上に設置した複数のブロッ
ク相互の間隔部を上下方向に沿って密封する目地材に関
するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint material which seals a space between a plurality of blocks installed on a foundation for a bank in a vertical direction.

いは油等が露出することになる。Prior art When constructing gravity-type revetment walls, breakwaters, and oil breakwaters, unless the space (joint) between blocks such as caisson and cellular blocks arranged and installed on a foundation is closed by a sealing means. The soil, oil, etc. behind the wall bank will be exposed through that part.
従来、目地材としては、可撓性材料（例えばゴム、合成

て、コストが増大する。Problems to be Solved by the Invention However, the joint material between the embankment blocks may move due to a pressure difference or wave force on both sides of the embankment. In order to prevent this, as shown in FIG. , A notch was provided on one of the surfaces that contact the interval between the opposing blocks, and joint material was inserted into this notch, but as a result, the manufacturing cost of the block increased and the notch The seal width of the joint material expands by the depth, the joint material becomes large, and the cost increases.
また目地材に浮力が加わって、基礎と目地材とに間隙が
生じ易い。Further, buoyancy is applied to the joint material, and a gap is likely to be formed between the foundation and the joint material.

のブロック相互の間隔部を密封することができる。MEANS FOR SOLVING PROBLEMS AND OPERATING EFFECTS The present invention relates to an improvement in a joint material for an embankment block that overcomes such difficulties, and one side edge of a flexible bag that is inflatable by injecting a filler, The flexible bag is jointly fixed to one surface of the surfaces facing the interval between the plurality of blocks in the vertical direction and integrally fixed, and a filler is injected into the flexible bag. By expanding the flexible bag, the space between the blocks can be sealed.

され、密封性能が確実に保持される。Further, in the present invention, in a state in which the side edges of the flat flexible bag are oriented in the vertical direction, the fixed side ear portion of the flat flexible bag is provided on one of the surfaces facing each other of the interval between the plurality of blocks. Since the flexible bags are integrally fixed, even if buoyancy or impact force due to waves is applied to the flexible bag, the flat flexible bag is stably clamped between the blocks without being flipped. , The sealing performance is surely maintained.

力が作用せず、該可撓性袋の耐久性も高い。Furthermore, in the present invention, since only the fixed side ears of the sea-side edge of the flat flexible bag are fixed to the end faces of the blocks, even if the degree of expansion by the filler changes, the flat flexible bag is Freely deformed without being constrained by fixing both ends, with close contact to both surfaces facing the gap between the blocks reliably and with high sealing performance, without excessive tensile stress acting on the flexible bag, The durability of the flexible bag is also high.

該可撓性袋の耐久性の一段の向上が可能となる。Furthermore, in the present invention, the flat flexible bag is reinforced with a reinforcing canvas, and a pressing metal fitting is applied to the surface of the fixed side ear portion of the flat flexible bag, and the block and the pressing metal fitting are attached by an anchoring means. Since the fixed side ear of the flat flexible bag is sandwiched in
A fixed side ear of the flat flexible bag does not generate a large stress around the hole like a bolt having a hole formed in the ear portion of the flat flexible bag and a nut is screwed to the bolt penetrating the hole. The mounting stress of the flat flexible bag is substantially evenly distributed over the entire portion and the strength of the flexible bag itself is significantly improved,
The durability of the flexible bag can be further improved.

土砂の流れを確実に阻止することができる。Moreover, in the present invention, since the fixed side ear portion of the flat flexible bag is fixed to the sea side of the block, the force from the land side to the sea side due to waves or ebb and flow can be applied to the flat side between the end faces of the block. When acting on the flexible bag, the free side edge of the flat flexible bag is strongly pressed against the block end surface of the opposite partner of the block to which the fixed ear of the flat flexible bag is attached. , It is possible to reliably block the flow of sediment that is about to flow from the land side to the sea side.
実施例 以下、第１図ないし第５図に図示された本発明の一実施
例について説明する。Embodiment An embodiment of the present invention shown in FIGS. 1 to 5 will be described below.
コンクリート製のケーソン１は、築堤のために、第１図
に図示されるように、複数個相互に隣接して基礎３上に
敷設されるようになっている。A concrete caisson 1 is laid on a foundation 3 adjacent to each other as shown in FIG. 1 for embankment.
一方、ケーソン１の相対する壁面２の間隙を塞ぐゴム製
可撓性袋10は、上端縁のみが開放し、その袋部11の外周
は全周に亘って補強帆布14で補強されるとともに、固定
側耳部12から自由端縁側耳部13に亘って補強帆布15で補
強されている。On the other hand, in the rubber flexible bag 10 that closes the gap between the wall surfaces 2 of the caisson 1 facing each other, only the upper edge is opened, and the outer periphery of the bag portion 11 is reinforced with the reinforcing canvas 14 over the entire circumference, It is reinforced with a reinforcing canvas 15 from the fixed side ear section 12 to the free edge side ear section 13.
また第２図に図示されるようにケーソン１の相対する一

る。As shown in FIG. 2, anchor bolts 4 are integrally planted on the sea side of one wall surface 2 of the caisson 1 facing each other in the horizontal direction at predetermined intervals in the vertical direction. After inserting the anchor bolt 4 through the fixed side ear portion 12 of the flexible bag 10, the pressing metal fitting 6 is placed on the surface of the fixed side ear portion 12, and the anchor bolt 4 protruding outward from the pressing metal fitting 6 is placed.
A flexible bag 10 is integrally attached to the wall surface 2 of the caisson 1 by screwing and tightening a nut 7 on the thread portion 5 of the.

可撓性袋10は第４図に図示されるように膨張し、同可撓
性袋10は、同可撓性袋10が付設されているケーソン１の
壁面２のみならず、これに相対した他方の可撓性袋10の
壁面２にも密着し、築堤の目地が閉塞される。After laying the caisson 1 provided with the flexible bag 10 on the foundation 3, the flowable filler 20 such as sand with water, underwater concrete, asphalt, and swelling material is press-fitted to obtain the same flexibility. The bag 10 expands as shown in FIG. 4, and the flexible bag 10 is not limited to the wall surface 2 of the caisson 1 to which the flexible bag 10 is attached, and the other flexible bag 10 opposite thereto. It also adheres to the wall surface 2 of the flexible bag 10 and blocks the joints of the embankment.
そして自由端縁側耳部13が陸側に配置されているため、
沖合からの波浪が築堤に打寄せられた後、海水が沖に向
って引いた時に、可撓性袋10をケーソン１の壁面２に押
付ける力が働いて、可撓性袋10は壁面２に強く密着する
ため、築堤の陸側海底部の土砂が沖に向って流出するこ
とが未然に防止される。And since the free edge side ear 13 is arranged on the land side,
After sea waves from the offshore hit the embankment, when the seawater is pulled offshore, the force that presses the flexible bag 10 against the wall surface 2 of the caisson 1 acts, and the flexible bag 10 is attached to the wall surface 2. Since it strongly adheres to the seawall, sediment on the land-side seabed of the embankment is prevented from flowing offshore.
また相対するケーソン１の壁面２の間隙が広い場合に
は、可撓性袋10の巾中央部が壁面２に接触しえなくなっ
ても、可撓性袋10の自由端縁側耳部13が、相対する壁面
２に押付けられるため、密封性は保持される。When the gap between the wall surfaces 2 of the caisson 1 facing each other is wide, even if the width center portion of the flexible bag 10 cannot contact the wall surface 2, the free edge side ear portion 13 of the flexible bag 10 is Since it is pressed against the opposing wall surfaces 2, the hermeticity is maintained.
さらに可撓性袋10はケーソン１の壁面２に固定されて付
設されているため、可撓性袋10に浮力が働いても、可撓
性袋10が上昇することはなく、可撓性袋10と基礎３との
間隙が広がる惧れはない。Furthermore, since the flexible bag 10 is fixedly attached to the wall surface 2 of the caisson 1, even if buoyancy acts on the flexible bag 10, the flexible bag 10 does not rise, and the flexible bag 10 does not rise. There is no fear of widening the gap between 10 and foundation 3.
第６図に図示するように、袋部の両端を耳部12,13を帆
布16で補強してもよく、また第７図に図示するように、
アンカーボルト４の頭部が突出しないように、固定側耳
部12を薄く形成してもよい。As shown in FIG. 6, both ends of the bag portion may be reinforced with ears 12 and 13 by canvas 16, and as shown in FIG. 7,
The fixed ear portion 12 may be formed thin so that the head portion of the anchor bolt 4 does not protrude.
また第８図に図示するように、固定側耳部12を厚さ方向
に亘って２分割してもよく、このような可撓性袋10で
は、製作が容易である。Further, as shown in FIG. 8, the fixed side ear portion 12 may be divided into two in the thickness direction, and such a flexible bag 10 is easy to manufacture.
