本発明は海浜、河川等を侵食から有効に防止す
るマツトの布設方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for laying pine to effectively prevent seashores, rivers, etc. from erosion.
従来、波や流れによつて起される土砂の侵食に
対する防止対策として、侵食部をシートで被覆
し、シートが外力で飛ばされないようにシートの
上に簡易な重錘をのせる方法がとられて来てい

Conventionally, as a preventive measure against earth and sand erosion caused by waves and currents, a method was used to cover the eroded area with a sheet and place a simple weight on top of the sheet to prevent it from being blown away by external forces. It's coming.
その一例として、実公昭51−9135号公報に記載
されているように、多数のコンクリートブロツク
をシートの上に接着した小規模の実施例がある。 As an example, there is a small-scale embodiment in which a large number of concrete blocks are glued onto a sheet, as described in Japanese Utility Model Publication No. 51-9135.
しかし、かかる構造体は、引張力に対しては有

抗することができなかつた。 However, while such structures were effective against tensile forces, they were less effective against tearing shear forces. That is, although sheets have a large allowable tensile stress, they are susceptible to tearing and cannot be relied on for shear resistance. Also, since the blocks were not interconnected, they were similarly unable to resist tearing shear forces.
更に、また従来の構造体では、実公昭51−9135

定した場合は、同工法の施工は不可能であつた。 Furthermore, in the conventional structure,
As in the method described in the publication, when the weight of the concrete block is small and the block mount is installed at the site, the method of grabbing the sheet and suspending it within the limit of the tensile stress of the sheet is used, so it is difficult to increase the weight of the block. This method was impossible if the weight of the blocks was assumed to be able to handle waves and currents with large external forces.
本発明は上記問題点を解決しようとするもので

In order to solve the above problems, in the present invention, a required number of blocks formed in shapes that can be connected to each other are connected to each other, and the blocks are bonded in advance to a sheet-like material, so that the blocks can be used for construction such as beaches where erosion prevention is required. When laying the cable at the installation location, the center of gravity of each of the required number of blocks is grasped with a hanging bracket, and the blocks and the sheet-like material are laid as one, which prevents undue stress from being applied to the sheet-like material. Erosion prevention mats can be installed without any damage.
以下本発明を添付図に示す実施例に基づいて具
体的に説明する。
The present invention will be specifically described below based on embodiments shown in the accompanying drawings.
第４図において、１はシート状物であり、２は

おり、これらは隣接するブロツク２の水平回転支
承用突起Ｂ及び水平回転支承用溝部Ａと回転自在
にかつ重合状態に係合する。 As shown in the figure, each of the blocks 2 has a horizontal rotation support groove A on the upper surface of one end, and a horizontal rotation support protrusion B on the lower surface of the other end. It engages with the support protrusion B and the horizontal rotation support groove A in a rotatable and overlapping state.
かかる構成によつて、各ブロツク２は隣接する
ブロツク２に対して垂直方向に十分な角度で回転

は水平回転支承用溝部Ａに重合状態に支持される
ので、各ブロツク２は隣接するブロツク２と一体
化され、単独で陥没するのを防止できる。 Such a configuration allows each block 2 to rotate through a sufficient angle in the vertical direction with respect to the adjacent block 2. In addition, horizontal rotation support protrusion B
Since each block 2 is supported by the horizontal rotation support groove A in an overlapping state, each block 2 is integrated with the adjacent block 2, and can be prevented from collapsing independently.
これらのブロツク２をシート状物１に取り付け

による結合力を利用するとともにシート状物１に
同ブロツク２を群体として接着剤等で結着する方
法を採る。 When attaching these blocks 2 to the sheet-like material 1, there is a method of connecting the blocks 2 to each other, utilizing the bonding force of the connection, and also bonding the same blocks 2 to the sheet-like material 1 as a group with adhesive or the like. take.
次に海浜等に侵食防止マツトを設置する本発明

可能となる。 Next, to explain the method of the present invention for installing anti-erosion mats on beaches, etc., the present invention does not involve grasping the sheet material 1 and suspending it, but instead grasping the center of gravity of each heavy block 2 with a hanging metal fitting. The sheet material 1 is suspended as a group to prevent stress from acting on the sheet material 1. This makes it possible to freely select a weight that can resist the large external forces of waves and currents.

Using a support frame 10 made of angle materials etc., block clamping tools 11 are provided at intervals of blocks 2,
A method is adopted in which the blocks 2 can be moved as a group by suspending them by a crane or the like using a chain 12 or the like.

As described above, according to the method for installing erosion prevention mats according to the present invention, instead of suspending the sheet to which concrete blocks are tied together,
Since the center of gravity of the required number of blocks is grasped with a hanging bracket and suspended together with the sheet, and then moved and lowered, no stress is applied to the sheet. It can be applied even in rough coastal areas, and compared to the conventional method of suspending both ends of a sheet with concrete blocks tied together and laying it at the required location.
This has the effect of greatly expanding the field of application.
