れるようにしている。(Prior Art) Fig. 5 shows a conventional product, which has a structure in which an opening 13 is directed from the inside to the outside in the horizontal portion 11 of a strip plate 10 in which horizontal portions 11 and inclined portions 12 are alternately bent. This structure has a structure in which the pile is installed downward, and even if earth and sand or stone blocks collapse from the hole wall during pile shaft excavation work, those that collide with the slope part 12 will be removed from the slope part 12.
The concrete is prevented from falling further downward and entering the inside of the liner plate, and when concrete is poured, a part of the concrete flows relatively smoothly from the opening 13 along the slope 12 to the outside of the liner. The gap between the hole and the hole wall, that is, the over-excavation space, is filled with concrete evenly and completely.
（考案が解決しようとする問題点）
叙上の従来品は杭坑掘削作業中における落石が
傾斜部を傷め、同傾斜部の梁としての強度が低下

よる損傷から保護する防護手段がない。(Problems to be solved by the invention) The conventional product mentioned above has the problem that falling rocks during pile shaft excavation work damage the sloped part, reducing the strength of the sloped part as a beam. There are no safeguards to protect against damage from falling rocks.

めに、開口部におけるコンクリートの流出具合は
一層悪い問題がある。 Another problem is that it is difficult to smoothly fill the voids with concrete during concrete placement. That is, since the opening is provided in a horizontal portion and does not face the direction of concrete pressure acting diagonally downward from the inside to the outside, concrete does not pass smoothly through the opening. Moreover, the concrete flowing down the slope after passing through the opening attempts to flow back into the opening at the lower end of the slope, i.e. near the opening, and tries to check each other. has an even worse problem.

……を設けると共に各流通口４の上縁から制流板
５を夫々背面側に向けて庇状に垂設している。 The liner plate 1 is suitably in the shape of a horizontally long flat plate or a bow plate shape as shown in the drawings, and the plate surface 2 is made of a single sheet steel plate exhibiting a corrugated shape, and a flange 3 is provided on the periphery of the plate surface 2. , flange 3
On the plate surface 2 surrounded by
. . . are provided, and a flow control plate 5 is provided hanging from the upper edge of each flow port 4 in the shape of an eave toward the back side.
フランジ３はプレート面２で隔てられている正
面側の上下左右の各フランジ面に相隣れるライナ
ープレート１の接続ボルト用通孔６…を開穿し、
背面側の左右各フランジ面にはコンクリートの流
通孔７…を開口している。 The flange 3 is made by opening connection bolt through holes 6 of the liner plate 1 adjacent to each of the upper, lower, left, and right flange surfaces on the front side separated by the plate surface 2,
Concrete flow holes 7 are opened in each of the left and right flange surfaces on the back side.
流通口４は、ライナープレート１の長さに比例
して、斜面部２ａに沿い等間隔状に適宜数設けら
れており、この流通口４は正面側に上向いている
斜面部２ａにおける上下すなわち谷部２ｂ最底部
から山部２ｃ最高部に亘り開口している。 The communication ports 4 are provided in an appropriate number at equal intervals along the slope portion 2a in proportion to the length of the liner plate 1, and the communication ports 4 are arranged in the upper and lower portions of the slope portion 2a facing upward to the front side, that is, in the valley. It is open from the bottom of part 2b to the highest part of mountain part 2c.
制流板５は各流通口４の上縁４ａから流通口の
背面側ほぼ上半部を覆い可能な庇状に垂下してお
り、且つその張出し角ａは板の両面に沿い流動す

砂の流入を最も阻止し得る。 The flow control plate 5 hangs down from the upper edge 4a of each flow port 4 in the shape of an eave that can cover almost the upper half of the back side of the flow port, and its projecting angle a is such that flowing concrete flows along both sides of the board. Both are set at favorable angles to facilitate smooth flow. In addition, it is desirable that the lower end of the flow control plate 5 has a horizontal angle b of approximately 20 degrees with respect to the lower edge 4b of the flow opening, so that even if the hole plate collapses, the slope portion 2a is protected from falling rocks, and the flow opening 4 is can best prevent the inflow of sediment.
流通口４および制流板５は斜面部２ａに対し
