【発明の詳細な説明】
本発明は地中アンカーを利用した護岸の築造法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of constructing a seawall using underground anchors.
従来、護岸を築造するには普通多数の鋼矢板を海底士中
に打込んで矢板壁を構成し、該壁体の上部をタィロッド
により１段又は２段繁緒して固定し該壁体背面に埋立を
行なうことにより行なっていた。Conventionally, in order to construct a seawall, a large number of steel sheet piles were driven into a seabed to form a sheet pile wall, the upper part of the wall was fixed with tie rods in one or two stages, and the back of the wall was reclaimed. This was done by doing the following.
しかしながら、この方法によると矢板打込費が高く、護

に、本発明の実施例を図によって説明する。However, this method has various drawbacks, such as the high cost of driving the sheet piles and problems with breaking strength because the arcuate sliding surface of the seawall is small. The present invention solves the problems of the conventional method as described above, and uses a new underground anchor that can strengthen the supporting capacity of the ground beneath the embankment body and provide a large arcuate sliding surface. This made it possible to easily construct a strong seawall without having to drive. Next, embodiments of the present invention will be described with reference to the drawings.

固定アンカー用ブロック４が取り付けられる。Figure 1 shows the underground anchor used in the method of the present invention, in which 1 is a plurality of parallel tension main members made of chain/wire rope, steel wire, or shaped steel, 2 is the main member 1 A plurality of parallel sub-villages made of synthetic fibers, glass fibers, net-like sheets, fiber mats, film-like sheets, asphalt mats, rubber sheets, concrete beams, H-steels or shaped steel materials, etc., loosely combined in a lattice pattern. Various methods can be considered for assembling the two materials 1 and 2 in a perpendicular direction, such as welding or weaving them in a lattice shape. The basic weave of the main material 1' is fixed to a steel material 3 such as H steel, and a fixed anchor block 4 such as a concrete block is attached to the tip.

２図に示す通り次のようにして造成される。Incidentally, each of the tip portions may be attached to a single fixed anchor shaped steel member or the like. A plurality of hinge mechanism parts 5 are formed on the steel material 3 at appropriate intervals, and a base end of a steel precast plate or a concrete plate which is to become a wall body 6 is connected to the hinge mechanism parts 5. As shown in Figure 2, the seawall will be constructed in the following manner.

ることができる。First, a mound 7 such as a rubble foundation is created on the seabed to a designed depth, and the connected body of the anchor A and the wall 6 configured as described above is sunk and laid on the mound 7 (Fig. 2A).
. Next, after reclamation is carried out on the anchor A and a backing plate 8 is turned on the upper part of the reclaimed soil (Figure 2), the wall 6 is erected and the upper part of the wall 6 and the above-mentioned backing plate 8 are tied together. 9, and then back-filling 10 with earth and sand is performed on the back surface of the upright wall 6. By sequentially connecting the upright walls 6 in this manner, a seawall can be easily constructed. In addition, the underground anchor used in the method of the present invention is particularly suitable for the main material 1 (
If necessary, the secondary material 2) is highly flexible, so the ground on which it is installed is not restricted, and the top load due to the reclaimed earth and sand on the anchor and the frictional force with the foundation ground can be effectively utilized. .
