Description

本発明は、河川や海岸等の護岸を目的として、土手や堤防の法面等に連続して配設されるコンクリート製の護岸ブロックに関し、特に、隣接するブロック間で、相互に連結できるように構成された護岸ブロックに関する。   The present invention relates to a concrete revetment block arranged continuously on a bank or bank slope for the purpose of revetment such as rivers and coasts, and in particular, so that adjacent blocks can be connected to each other. Concerning the revetment block constructed.

従来より、土手や堤防の法面等にコンクリート製の護岸ブロック（被覆ブロック）を多数設置して、土手等の表面を被覆するという工事が行われており、かかる護岸工法に使用される護岸ブロックとしては、現在まで、実に様々な形状、或いは、構造のコンクリートブロックが開発され、実用化されている。   Conventionally, many revetment blocks (covering blocks) made of concrete have been installed on the slopes of banks and embankments to cover the surfaces of banks, etc., and the revetment blocks used for such revetment methods Until now, concrete blocks of various shapes or structures have been developed and put to practical use.

例えば、特開平１１−３１５５２７号公報には、端部にそれぞれ蝶番状連結部（連結手段）を形成し、隣接するブロック同士を連結した状態で法面等に設置できるようにして、河川水流や波浪等に対し所望の安定性が得られるように構成した護岸ブロックが開示されている。
特開平１１−３１５５２７号公報 For example, in Japanese Patent Application Laid-Open No. 11-315527, a hinge-shaped connecting portion (connecting means) is formed at each end so that adjacent blocks are connected to each other so that they can be installed on a slope or the like. A revetment block configured to obtain desired stability against waves and the like is disclosed.
JP 11-315527 A

しかしながら、上記のような従来の護岸ブロックは、相互に連結可能であるとは言え、一方のブロックの溝内に嵌合させた他のブロックの突起は、上方に対して規制されておらず、自重によって（つまり、重力に従って）連結状態が維持される構造となっているため、作用する水流の圧力のうち、上又は斜め上向きに作用する力（揚力）に対して充分な安定性を得ることができない、という問題がある。   However, although the conventional revetment blocks as described above can be connected to each other, the protrusion of the other block fitted in the groove of one block is not restricted to the upper side, Since the connection is maintained by its own weight (that is, according to gravity), sufficient stability is obtained with respect to the force (lift) acting upward or obliquely upward in the pressure of the acting water stream. There is a problem that can not be.

本発明は、このような従来技術における問題を解決すべくなされたものであって、隣接する護岸ブロック間で強固な連結状態を得ることができ、揚力に対しても充分な安定性を期待できる護岸ブロックを提供することを目的とする。   The present invention has been made to solve such problems in the prior art, and can provide a strong connection between adjacent revetment blocks, and can be expected to have sufficient stability against lift. The purpose is to provide a revetment block.

本発明に係る護岸ブロックは、連結手段（本体の側方へ向かって開口し、対向する二つの顎部間において上方が開放された構造の溝と、本体の側方へ向かって突出するように構成された突起とからなる）を有し、この連結手段を介して、隣接するブロック同士を連結できるように構成されており、他の護岸ブロックに対する傾斜角度が所定の範囲にある場合のみ、他の護岸ブロックの顎部間からその溝内へ、突起を進入させることができるように構成されていることを特徴としている。   The revetment block according to the present invention includes a connecting means (a groove having a structure that opens toward the side of the main body and is open between two opposing jaws, and protrudes toward the side of the main body. It is configured so that adjacent blocks can be connected to each other through this connecting means, and only when the inclination angle with respect to the other revetment block is within a predetermined range. It is characterized in that the projection can be made to enter from between the jaws of the revetment block into the groove.

尚、「傾斜角度の範囲」は、所定の進入角±３°（許容誤差）であることが好ましく、更に、前記進入角は、３０〜６０°の範囲内で設定されることが好ましい。また、溝の内径は、内部側から外側へ向かって次第に大きくなるように設定されていることが好ましい。   The “inclination angle range” is preferably a predetermined entry angle ± 3 ° (allowable error), and the entry angle is preferably set within a range of 30 to 60 °. The inner diameter of the groove is preferably set so as to gradually increase from the inner side toward the outer side.

本発明に係る護岸ブロックは、他の護岸ブロックの溝内に係合させた突起が、上方に対して規制される構造となっているため、隣接する護岸ブロック間で強固な連結状態を得ることができ、その結果、揚力に対しても、充分な安定性を期待することができる。   The revetment block according to the present invention has a structure in which the protrusion engaged in the groove of another revetment block is restricted to the upper side, so that a strong connection state is obtained between adjacent revetment blocks. As a result, sufficient stability can be expected for lift.

また、溝の内径が、内部側から外側へ向かって次第に大きくなるように設定した場合には、護岸ブロックを配設しようとする地盤において多少の凹凸がある場合や、地盤の勾配が緩やかに変化している場合であっても、地盤が平らである場合と同様に、好適に連結させることができる。即ち、断面方向にも延長方向にも自由に変形可能な継ぎ目（いわゆるユニバーサルジョイント）の機能を有することとなり、設置時の護岸勾配の変化や、不陸に対し、柔軟に対応できる。また、洪水時の土の吸い出しによる地盤の変形にも柔軟に対応でき、法面の保護機能を損ないにくい構造とすることができる。   In addition, when the inner diameter of the groove is set to gradually increase from the inside to the outside, there may be some unevenness in the ground where the revetment block is to be installed, or the slope of the ground will change slowly. Even if it is the case where it is doing, it can connect suitably like the case where the ground is flat. That is, it has the function of a seam (so-called universal joint) that can be freely deformed in both the cross-sectional direction and the extension direction, and can flexibly cope with changes in the revetment slope during installation and unevenness. In addition, it is possible to flexibly cope with the deformation of the ground due to the sucking out of soil during a flood, and it is possible to make a structure that does not impair the protective function of the slope.

以下、添付図面に沿って、本発明を実施するための最良の形態について説明する。図１は、本発明の第１の実施形態に係る護岸ブロック１の斜視図、図２は平面図、図３は側面図である。   The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of a revetment block 1 according to a first embodiment of the present invention, FIG. 2 is a plan view, and FIG. 3 is a side view.

図示されているように、この護岸ブロック１においては、本体の一端側（先端部側）に溝２が一つ形成され、他端側に突起３（３ａ，３ｂ）が二つ形成されている。これらの突起３ａ，３ｂは、本体の側方（左右方向）へ向かってそれぞれ突出し、溝２は、中心線（中心軸線）が、突起３ａ，３ｂの突出方向と平行となるような向きに形成され、本体の側方（左右方向）へ向かって開口するとともに、対向する二つの顎部２ａ，２ｂ間において上方が開放された構造となっている。   As shown in the figure, in this revetment block 1, one groove 2 is formed on one end side (tip side) of the main body, and two projections 3 (3a, 3b) are formed on the other end side. . These protrusions 3a and 3b protrude toward the side (left and right direction) of the main body, respectively, and the groove 2 is formed so that the center line (center axis) is parallel to the protruding direction of the protrusions 3a and 3b. In addition, the structure opens to the side (left and right direction) of the main body, and the upper part is opened between the two jaw portions 2a and 2b facing each other.

本実施形態の護岸ブロック１も、特開平１１−３１５５２７号公報等に記載されている従来の護岸ブロックと同様に、連結手段を介して（即ち、一のブロックの突起３を、他のブロックの溝２内へ係合させることによって）、隣接するブロック同士を連結できるように構成されている。   Similarly to the conventional revetment block described in Japanese Patent Application Laid-Open No. 11-315527, etc., the revetment block 1 of the present embodiment is also connected via a connecting means (that is, the protrusion 3 of one block is connected to the other block). By being engaged into the groove 2), adjacent blocks can be connected.

尚、従来の護岸ブロックにおいては、自重によって連結状態が維持される構造となっているため（一方のブロックの溝内に係合させた他のブロックの突起が、上方に対して規制されていないため）、揚力に対して充分な安定性を得ることができないという問題があったが、本実施形態の護岸ブロック１においては、一方の護岸ブロック１の溝２内に係合させた他の護岸ブロック１の突起３が、上方に対して規制される構造となっており、揚力に対しても、充分な安定性を得ることができる。   In addition, in the conventional revetment block, since it has a structure in which a connection state is maintained by its own weight (the protrusion of the other block engaged in the groove of one block is not restricted upward. However, in the revetment block 1 of the present embodiment, there is another problem that the revetment block engaged in the groove 2 of one revetment block 1 is not obtained. The protrusion 3 of the block 1 has a structure that is restricted upward, and sufficient stability can be obtained even with respect to lift.

この点について具体的に説明すると、図１及び図３に示されているように、溝２は、護岸ブロック１の上面において上方が開放された、断面の内側輪郭形状が円弧状となるような形状となっている。この溝２の内部には、図４（３）に示すように、他の護岸ブロック１の突起３を嵌合させることができるようになっている。つまり、突起３は、溝２よりも僅かに小さい寸法に設定されている。   Specifically, as shown in FIG. 1 and FIG. 3, the groove 2 is open at the upper surface of the revetment block 1, and the inner contour shape of the cross section becomes an arc shape, as shown in FIGS. 1 and 3. It has a shape. As shown in FIG. 4 (3), the protrusions 3 of other revetment blocks 1 can be fitted inside the groove 2. That is, the protrusion 3 is set to a size slightly smaller than the groove 2.

但し、図３に示すように、溝２は、中央部付近の横幅（横幅寸法Ｗ２）に比べて、上面における顎部２ａ，２ｂ間の寸法（開放幅寸法Ｗ１）が若干狭くなっているところ、図４（１）に示すように、突起３は、護岸ブロック１を水平に保持した場合における横幅寸法Ｖ１が、顎部２ａ，２ｂ間の開放幅寸法Ｗ１よりも大きくなるように設定されているため、連結しようとする二つの護岸ブロック１，１が平行な状態にある場合には、一方の護岸ブロック１の突起３を、他方の護岸ブロック１の顎部２ａ，２ｂ間から（つまり、上面側から）溝２内へ進入させることはできない。   However, as shown in FIG. 3, the groove 2 has a slightly narrower dimension (open width dimension W1) between the jaws 2a and 2b on the upper surface than the lateral width (lateral width dimension W2) near the center. As shown in FIG. 4 (1), the protrusion 3 is set so that the lateral width dimension V1 when the revetment block 1 is held horizontally is larger than the open width dimension W1 between the jaw portions 2a and 2b. Therefore, when the two revetment blocks 1 and 1 to be connected are in a parallel state, the protrusion 3 of one revetment block 1 is moved from between the jaw portions 2a and 2b of the other revetment block 1 (that is, It cannot enter into the groove 2 (from the top side).

ところが、本実施形態においては、突起３が特徴的な形状をしており、図４（２）に示すように、連結しようとする護岸ブロック１を、他方の護岸ブロック１に対して、４５°傾斜させた場合、突起３の横幅寸法Ｖ２が、顎部２ａ，２ｂ間の開放幅寸法Ｗ１よりも小さくなるように構成されている。このため、連結しようとする護岸ブロックを、４５°という傾斜角度を維持しつつ移動させていけば、突起３を、顎部２ａ，２ｂ間から溝２内へ進入させることができる。   However, in this embodiment, the protrusion 3 has a characteristic shape. As shown in FIG. 4B, the revetment block 1 to be connected is 45 ° to the other revetment block 1. When inclined, the lateral width dimension V2 of the projection 3 is configured to be smaller than the open width dimension W1 between the jaw portions 2a and 2b. For this reason, if the revetment block to be connected is moved while maintaining an inclination angle of 45 °, the protrusion 3 can enter the groove 2 from between the jaws 2a, 2b.

尚、突起３を、他のブロックの溝２内へ進入させることが可能となる護岸ブロック１の傾斜角度を、ここでは特に「進入角」と言う。上述の通り、本実施形態においては、進入角は４５°に設定されているが、必ずしもこの角度には限定されず、３０〜６０°の範囲内で、任意の角度に設定することができる。また、護岸ブロック１が、設定されている進入角から１°でも外れると、溝２内への突起３の進入が不可能になる、という訳ではなく、実際には、設定されている進入角を中心として上下３°の範囲（許容誤差の範囲）内にあるときに（つまり、進入角が４５°である場合には、４２°から４８°までの６°の範囲内にあるときに）、突起３を他のブロックの溝２内へ進入させることができるようになっている。   In addition, the inclination angle of the revetment block 1 that allows the protrusion 3 to enter the groove 2 of another block is specifically referred to herein as an “entrance angle”. As described above, in this embodiment, the approach angle is set to 45 °, but is not necessarily limited to this angle, and can be set to an arbitrary angle within a range of 30 to 60 °. In addition, if the revetment block 1 deviates even by 1 ° from the set approach angle, it does not mean that the protrusion 3 cannot enter the groove 2 but actually the set approach angle. Is within the range of 3 ° up and down (tolerance range) around the center of the angle (that is, when the approach angle is 45 °, it is within the range of 6 ° from 42 ° to 48 °) The protrusion 3 can be inserted into the groove 2 of another block.

そして、突起３を、他方の護岸ブロック１の溝２内へ進入させ、完全に嵌合させたら、連結した一方の護岸ブロック１を、他方の護岸ブロック１に対する傾斜角度が４５±３°の範囲外となるように（例えば、図４（３）に示すように、他方の護岸ブロック１と同一の角度姿勢となるように）回動させる。そうすると、突起３の横幅寸法が、顎部２ａ，２ｂ間の開放幅寸法Ｗ１よりも大きくなり、突起３は、上方に対して移動が規制されることになる。つまり、突起３は溝２から外れない状態となり、隣接する護岸ブロック１間で強固な連結状態が得られ、その結果、揚力に対しても、充分な安定性を期待することができる。   When the protrusion 3 is inserted into the groove 2 of the other revetment block 1 and completely fitted, the one revetment block 1 connected to the other revetment block 1 has an inclination angle of 45 ± 3 °. It is rotated so that it is outside (for example, as shown in FIG. 4 (3), the angle and posture are the same as the other revetment block 1). Then, the lateral width dimension of the protrusion 3 becomes larger than the open width dimension W1 between the jaw portions 2a and 2b, and the protrusion 3 is restricted from moving upward. That is, the protrusion 3 is not detached from the groove 2, and a strong connection state is obtained between the adjacent revetment blocks 1, and as a result, sufficient stability can be expected for lift.

以上に説明したような本実施形態の護岸ブロック１の特徴的な構造をより端的に表現すると、ある護岸ブロックの突起を、他の護岸ブロックの上面側から溝内へ嵌合させて両者を連結しようとする場合、当該護岸ブロックの傾斜角度（他の護岸ブロックに対する傾斜角度）が所定の範囲（本実施形態においては４５°（進入角）±３°（許容誤差）の範囲）にある場合のみ、他の護岸ブロックの上面側から（顎部間から）その溝内へ、当該護岸ブロックの突起を進入させることができ、また、当該護岸ブロックの突起を他の護岸ブロックの溝内に嵌合させた状態にある場合には、当該護岸ブロックの傾斜角度が所定の範囲（本実施形態においては４５±３°の範囲）にある場合のみ、当該護岸ブロックの突起を、他の護岸ブロックの上面側から取り外して連結を解除することができ、その角度範囲外にある限り、連結状態を解除できないようになっている、ということである。   When the characteristic structure of the revetment block 1 according to the present embodiment as described above is expressed more simply, a protrusion of a revetment block is fitted into a groove from the upper surface side of another revetment block and the two are connected. When trying to do so, only when the inclination angle of the revetment block (inclination angle with respect to other revetment blocks) is within a predetermined range (in this embodiment, 45 ° (entrance angle) ± 3 ° (allowable error)). The protrusion of the revetment block can be inserted into the groove from the upper surface side of another revetment block (between the jaws), and the protrusion of the revetment block fits into the groove of another revetment block In the case where the revetment block is in an inclined state, only when the inclination angle of the revetment block is within a predetermined range (in this embodiment, a range of 45 ± 3 °), the protrusion of the revetment block is placed on the upper surface of another revetment block. Take from the side The connection state can be released and the connection state cannot be released as long as it is outside the angular range.

図５は、河川の堤防（土手）に本実施形態の護岸ブロック１を多数配置して構築した被覆工の施工例を示す図である。この図において４は堤防の下面、５は堤防の法面、６は堤防の天端面であり、図示されているように、本実施形態の護岸ブロック１を使用すれば、連続的に配置した護岸ブロック１をそれぞれ強固に連結することにより、堤防の下面４から、法面５、そして天端面６に至るまで、被覆工を一体化することができる。   FIG. 5 is a diagram showing a construction example of a covering work constructed by arranging a large number of revetment blocks 1 of the present embodiment on a river bank (bank). In this figure, 4 is the bottom surface of the levee, 5 is the slope of the levee, and 6 is the top end surface of the levee. As shown in the figure, if the revetment block 1 of this embodiment is used, the revetment continuously arranged By firmly connecting the blocks 1, the covering work can be integrated from the bottom surface 4 of the dike to the slope 5 and the top end surface 6.

尚、本実施形態の護岸ブロック１は、溝２の内径が、図６に示すように、内部側から外側（水平方向外側）へ向かって次第に大きくなるように設定されている（図６に示すＹ１（最奥部の内径）、Ｙ２（最も外側の内径）参照）。このため、護岸ブロック１を配設しようとする地盤において多少の凹凸がある場合や、地盤の勾配が緩やかに変化している場合にも柔軟に対応することができ、地盤が平らである場合と同様に、好適に連結させることができる。   In addition, the revetment block 1 of this embodiment is set so that the internal diameter of the groove | channel 2 may become large gradually toward an outer side (horizontal direction outer side) from an inner side, as shown in FIG. Y1 (innermost inner diameter), Y2 (outermost inner diameter)). For this reason, when there is some unevenness in the ground on which the revetment block 1 is to be disposed, or when the slope of the ground is gently changing, it is possible to flexibly cope with the case where the ground is flat. Similarly, it can connect suitably.
