The movement regulation means 5 is constituted so as to press down the outside of any leg part of the foot protection block 12 by this rail-like movement regulation means 5, by fixing a rail-like object of extending in the parallel direction to a boundary line between the inclined plane 3 and the slope tip outer peripheral part 4, on the ground of the slope tip outer peripheral part 4.SELECTED DRAWING: Figure 1

Description

本発明は、港湾、海岸、漁港等の構造物のマウンドの構造に関する。   The present invention relates to a structure of a mound of a structure such as a harbor, a coast, and a fishing port.

港湾、海岸、漁港等の構造物は、地盤上に捨石等を積み上げて形成された台形状のマウンドを基礎とするものが多く、このようなマウンドは、傾斜面、天端面が被覆ブロックによって被覆されるとともに、洗掘の防止、及び、傾斜面の被覆ブロックの移動の防止等の理由から、法先外周部の地盤上に根固めブロックが配置されるのが一般的である。   Many structures such as harbors, coasts, fishing ports, etc. are based on trapezoidal mounds formed by stacking rubble on the ground, and such mounds are covered with covering blocks on the inclined surfaces and the top end surfaces. In addition, for reasons such as prevention of scouring and prevention of movement of the covering block on the inclined surface, it is common to place a consolidation block on the ground at the outer periphery of the tip.

法先外周部に配置される根固めブロックは、条件によっては波浪に対する安定性が低いという問題があり、例えば、波浪等の影響を受けて根固めブロックが外側方向へ移動してしまうと、傾斜面に配置されている被覆ブロックが法先側に順次スライドして、各被覆ブロック間に隙間が生じ、緊密な配列によって担保されているマウンド全体の安定性が損なわれてしまうという問題がある。   The root block placed on the outer periphery of the tip has a problem that the stability against waves is low depending on the conditions.For example, if the root block moves outward due to the influence of waves, etc. There is a problem that the covering blocks arranged on the surface slide sequentially to the tip side, and a gap is generated between the covering blocks, and the stability of the entire mound secured by the close arrangement is impaired.

本発明は、このような従来技術における課題を解決しようとするものであって、法先外周部に配置される根固めブロックにおける安定性の飛躍的な向上を期待できるマウンドを提供することを目的とする。   An object of the present invention is to provide a mound that is intended to solve such a problem in the prior art and can be expected to drastically improve the stability of a consolidation block disposed on the outer periphery of the tip. And

本発明に係るマウンドは、被覆ブロックが傾斜面に配置されるとともに、根固めブロックが法先外周部に配置され、法先外周部に配置した根固めブロックの外側方向への移動を規制する移動規制手段を、法先外周部の地盤上に設置したことを特徴としている。   In the mound according to the present invention, the covering block is disposed on the inclined surface, the root-solidifying block is disposed on the outer periphery of the tip, and the movement for restricting the outward movement of the root-setting block disposed on the outer periphery of the tip It is characterized in that the regulating means is installed on the ground at the outer periphery of the law.

尚、根固めブロックとしては、本体底部よりも下方へ突出した脚部を有するものを使用することが好ましく、また、傾斜面と法先外周部との境界線と平行な方向へ延在するレール状の移動規制手段を法先外周部の地盤上に設置し、このレール状の移動規制手段により、根固めブロックのいずれかの脚部の外側を押さえるように構成することが好ましい。   In addition, it is preferable to use what has a leg part which protrudes below from the bottom part of the main body as the rooting block, and the rail extends in a direction parallel to the boundary line between the inclined surface and the outer periphery of the tip. It is preferable that the shape-like movement restricting means is installed on the ground of the outer periphery of the legal tip, and the rail-like movement restricting means is configured to press the outside of any leg portion of the rooting block.

また、レール状の移動規制手段の代わりに、リング状の移動規制手段を法先外周部の地盤上に配置し、一つの移動規制手段の内側に、二列×二列の四つの根固めブロックにおける最も内側の脚部をそれぞれ一つずつ挿入することにより、四つの根固めブロックを移動規制手段によって結束するように構成してもよい。   Also, instead of the rail-shaped movement regulating means, a ring-shaped movement regulating means is arranged on the ground of the outer periphery of the legal tip, and four rooting blocks of two rows × two rows are placed inside one movement regulating means. The four innermost legs may be inserted one by one, so that the four root blocks are bound by the movement restricting means.

また、根固めブロックとして、天端面から底面まで貫通する穴が形成されたものを使用し、移動規制手段として、ベースから上方へ突出した二列×二列の四つの突起を有するものを使用し、一つの移動規制手段の上に、二列×二列に配列された四つの根固めブロックを載置し、移動規制手段の四つの突起が、載置される四つの根固めブロックの各穴に一つずつ嵌合されるように構成してもよい。   In addition, use a root block that has a hole that penetrates from the top surface to the bottom, and use a movement control means that has four projections in two rows x two rows that protrude upward from the base. The four rooting blocks arranged in two rows and two rows are placed on one movement restricting means, and the four protrusions of the movement restricting means are placed in the holes of the four rooting blocks to be placed. May be configured to be fitted one by one.

本発明に係るマウンドは、法先外周部に設置した移動規制手段によって、根固めブロックの脚部が押さえられることにより、又は、二列×二列に配列された四つの根固めブロックが結束或いは連結されることにより、外周側への移動が規制されるようになっているため、波浪等に対する根固めブロックの安定性の飛躍的な向上が期待できる。   In the mound according to the present invention, the leg portions of the root block are pressed by the movement restricting means installed on the outer periphery of the tip, or four root blocks arranged in two rows × two rows are bound or bound. Since the movement to the outer peripheral side is regulated by being connected, a dramatic improvement in the stability of the consolidation block against waves and the like can be expected.
