【考案の詳細な説明】
この考案は、砂防堰堤や水流調節堰堤などの角
部分を保護する材料に関する。[Detailed description of the invention] This invention relates to a material for protecting the corner portions of erosion control dams, water flow control dams, etc.
これらの堰堤は、増水等に溢流する際に、上流

う深い亀裂を伴うことがあり、このような亀裂は
堰堤の崩壊の原因になる。 When these dams are overflowing due to rising water, rocks brought from upstream collide violently with them, and the corners in particular can be severely damaged by the collision. Such corner failures are sometimes accompanied by deep inward cracks, which can cause the dam to collapse.
この考案は、堰堤の角部分を岩石等の衝突から
保護することを目的とする。 The purpose of this idea is to protect the corners of the dam from collisions with rocks, etc.
この考案による保護体は、堰堤の角部分に取付

の取付座の中心には、補強体を貫通し堰堤に接す
る側の面に達する取付孔が穿設されている。 The protector according to this invention has a roughly L-shaped cross section and is made of thick rubber material in order to be attached to the corner of the dam. A plate-shaped reinforcing body is embedded in this rubber material close to the surface in contact with the dam, and a mounting seat is recessed at a suitable location on the outer surface. A mounting hole is bored in the center of this mounting seat, passing through the reinforcing body and reaching the surface on the side that contacts the dam.
以下この考案の実施例を図に基いて説明する。 Examples of this invention will be described below with reference to the drawings.

における保護体４及び６は、折曲げ角度が90゜よ
り大きい点を除けば、保護体５と同構造である。 Figures 2 and 3 show the protective body 5 in Figure 1.
This protector 5 has a rounded rubber member 7 bent at 90 degrees, and has a steel plate 8 embedded therein close to the back surface 5b, and an oblong mounting seat 9, 9 are recessed, and oval mounting holes 10, 10... are bored through the steel plate 8 from the bottom surface of these mounting seats toward the back surface 5b. Note that the protectors 4 and 6 in FIG. 1 have the same structure as the protector 5 except that the bending angle is greater than 90 degrees.

6 is fitted into the recess 12 after the concrete hardens, and the bolts 14, 1 are inserted through the mounting holes 10, 10...
4. It is fixed by...
洪水時等には、水流１５は堰堤を越えて激しく
溢流するが、その際に岩石１６，１６を押流す。
この岩石１６，１６は堰堤の各所に衝突するが、
平坦な面に衝突した際に堰堤に大きな被害を与え

しばしばコンクリート部分１１の内部へ向う亀裂
を生ずることがある。この亀裂は、気候変化によ
つて生長し、遂には堰堤そのものを破壊に至ら
せ、洪水時等に欠壊により人命財産に多大の被害
をもたらす原因を作る。 During a flood or the like, the water flow 15 violently overflows over the dam, but at this time it washes away the rocks 16, 16.
These rocks 16, 16 collide with various parts of the dam,
It is rare for a dam to be seriously damaged when colliding with a flat surface. However, if it collides with a corner,
Cracks often develop into the concrete part 11. These cracks grow due to climate change and eventually lead to the destruction of the dam itself, causing great damage to human life and property due to failure during floods.
ところが、第１図並びに第４図に示すように、
堰堤の角部分にこの考案による保護体を取付けて
おけば、ゴム材が持つ緩衝作用と耐摩耗性とによ
つて、最も脆弱な角部分を効果的に保護する。 However, as shown in Figures 1 and 4,
If a protector according to this invention is attached to the corner of a dam, the most vulnerable corner will be effectively protected by the cushioning effect and abrasion resistance of the rubber material.
以上のように、この考案によるときは、堰堤の
最も脆弱な部分を保護できるので、堰堤の寿命を
延長し、かつ堰堤の欠壊による人命財産の被害を
予防するのに貢献する。 As described above, this invention can protect the most vulnerable part of the dam, thereby extending the life of the dam and contributing to preventing damage to human life and property due to dam failure.
