本考案は擁護壁が施工された法面やトンネル壁
の裏面での排水を効果的に行わしめるための排水
材に関する。[Detailed Description of the Invention] The present invention relates to a drainage material for effectively draining water from the back side of a slope or tunnel wall where a protection wall has been constructed.
例えば、第１図に例示されている造成地Ａ等の
法面A1にその擁護壁Ｂが施工されている場合、
地中に浸入した雨水や地下水の排水を効果的に行
わしめるために、一般に、法面A1と擁護壁Ｂと
の間に排水材１を施工すると共に、この排水材１
の下端に有孔排水管１００を埋設しておくことに
よつて、法面A1から出る水を排水材１によつて
有孔排水管１００に導いて排水するようにしてい
る。 For example, if the protection wall B is constructed on the slope A 1 of the developed land A etc. illustrated in Fig. 1,
In order to effectively drain rainwater and groundwater that have entered the ground, generally a drainage material 1 is constructed between the slope A 1 and the protection wall B, and this drainage material 1 is
By embedding a perforated drain pipe 100 in the lower end of the slope A1, water coming out of the slope A1 is guided to the perforated drain pipe 100 by the drainage material 1 and drained.
従来、この種の用途に使用される排水材として

より礫や小石等の間隙が泥詰まりを起し、良好な
排水性能を長期に亘つて維持し難い問題があつ
た。また、その施工が面倒で、多大な労力と時間
を要する問題もあつた。 Conventionally, the drainage material used for this type of purpose was to place gravel, pebbles, etc. between the slope and the protection wall, but it has been found that over time, gravel, pebbles, etc. The gap became clogged with mud, making it difficult to maintain good drainage performance over a long period of time. There was also the problem that the construction was troublesome and required a great deal of labor and time.
本考案は従来の問題点に鑑みてなされたもの
で、長期に亘つて良好な排水性能の維持を期待で
き、しかもその施工を容易かつ迅速にできる排水
材を提供することを目的とする。 The present invention was made in view of the conventional problems, and the purpose is to provide a drainage material that can be expected to maintain good drainage performance over a long period of time and can be constructed easily and quickly.
上記目的を達成するために、本考案による排水

である。 In order to achieve the above object, the drainage material according to the present invention has a plate having ribs with a large number of holes, and prevents mud from passing through the holes and impairing the drainage performance of the drainage material. In order to do this, a screen that allows only water to pass through is provided on the plate.
以下、図示した実施例にしたがつて本考案を説
明する。 The present invention will be described below with reference to the illustrated embodiments.

る。 In the drainage material 1 illustrated in FIG. 2, the plate 2 is made of a plastic molded product made of high-density polyethylene, polypropylene, etc., and has a large number of through holes 3. That is, the plate body 2 has rib-like protrusions 4 having a V-shaped cross section that protrude toward the back side thereof and are arranged side by side so as to extend along each other. In the illustrated example, a plurality of rib-like protrusions 5 in a direction perpendicular to the protrusion 4 are arranged side by side along each other,
As is clear from FIG. 3, this protrusion 5 is located closer to the bottom of the back than the protrusion 4. On the other hand, as shown in FIG.
is placed by pasting or other appropriate means.

ように、スクリーン６及び板体２の透孔３を通過
した後、通水路Ｒを経て下方へ排出される。この
場合、スクリーン６は水のみの通過を許し、泥土
等の固形物の通過を阻止するので、経年によつて
もこれらの固形物が透孔３や通水路Ｒを塞ぐこと
はない。 This drainage material 1 is used as a protection wall B as explained in FIG.
When using the screen 6 as a drainage material, as shown in Fig .
It is interposed between the slope A 1 and the protection wall B so that the tall protrusion 4 is in contact with the slope and in the vertical direction.
In this way, the tall protrusion 4 is placed on the slope A 1
A plurality of water passages R partitioned off by the protrusions 4 are formed on the back side of the protection wall B, since they serve as spacers to set a predetermined distance between the protection wall B and the protection wall B. Therefore, the underground water passes through the screen 6 and the through holes 3 of the plate body 2, and then is discharged downward through the water passage R, as shown by the arrow in the figure. In this case, the screen 6 allows only water to pass through and prevents solid matter such as mud from passing through, so that these solid matters will not block the through holes 3 and the water passageway R even over time.
また、排水材１は、上記のように所定の板体２
にスクリーンを配設してなる平板状のものである
ので、その施工にあたつては、排水材１を例えば
第４図に示した法面A1に沿つて縦横に配置する
だけで済む。 In addition, the drainage material 1 is attached to a predetermined plate body 2 as described above.
Since the drainage material 1 is in the form of a flat plate with a screen disposed on its surface, the drainage material 1 need only be arranged vertically and horizontally along the slope A1 shown in FIG. 4, for example.

ことにも役立つ。 Furthermore, since the drainage material 1 explained in FIG. 2 has the plate body 2 made of a plastic molded product, there is no risk of rusting, etc., and good drainage performance is maintained over a long period of time. Instead, the tall rib-like projection 4 can exert a hinge action at its head, so even if the slope A 1 in FIG. 4 is curved or bent in plan view,
There is an advantage that the drainage material 1 can be easily constructed by curving or bending it along the slope A1 using the hinge action of the top of the projection 4. In addition, if the slope A 1 in Fig. 4 is curved in a vertical cross-sectional view,
By utilizing the hinge action performed at the top of the low protrusion 5, there is an advantage that the drainage material 1 can be bent and constructed along the slope A1 . Furthermore, the above-mentioned 2
The seed protrusions 4 and 5 are not only effective in ensuring that the drainage material 1 follows the slope B as described above, but also in the rectangular flat area surrounded by these protrusions 4 and 5. It also serves to reinforce the structure due to its ribbed effect.

く、長期に亘つて良好な排水性能が維持される。 FIG. 5 shows a modification of the construction method for the drainage material 1. That is, in this construction method, the plate body 2 is backed up by filling the passageway R explained in FIG. 4 with pebbles and gravel 7. In this case, the water that has passed through the screen 6 and the through holes 3 is
The mud is discharged downward through the gap, but at this time, the screen 6 prevents the mud from entering as described above, so the gap is not blocked and good drainage is maintained for a long time. Performance is maintained.

The spacer action of the rib-like protrusions provided on the plate securely holds the water passage, and it can also be easily arranged vertically and horizontally along the slope, making construction quick and easy. Furthermore, mud clogging and the like are reliably prevented by the action of the screen disposed on the surface of the plate, and good drainage performance is maintained over a long period of time. Note that the drainage material of the present invention is not limited to being used as a drainage material for the protection wall described in the embodiment, but can be similarly used as a drainage material constructed on the back side of a tunnel wall, etc.
