【考案の詳細な説明】
本考案は道路の側縁や圃場整備に使用する集水
用排水溝に関するものであり、特に集水機能の低
下を防止せんとしたものである。[Detailed Description of the Invention] The present invention relates to a drainage ditch for collecting water used for road side edges and field maintenance, and is particularly aimed at preventing deterioration of the water collection function.
従来、集水を目的とした排水路は、側壁に孔が
穿設され、そこから集水されていたが、土砂の重
力や、乾燥の操り返えしで徐々に、集水孔周囲の
土砂の空隙率が減少して透水性が低下するため、
集水機能を果さなくなる現象が多くみられた。つ
まり土砂が溝の側壁にそつて徐々に下除し、その
ため集水孔の周囲の土砂が締つて空隙率が低下す
ることによるのである。 Traditionally, drainage channels for the purpose of collecting water had holes drilled in the side walls to collect water, but due to the gravity of the sediment and the repeated drying, the sediment around the holes gradually disappeared. As the porosity decreases and the water permeability decreases,
There were many cases where the water collection function was no longer fulfilled. In other words, the earth and sand gradually move down along the side walls of the ditch, and as a result, the earth and sand around the water collection hole becomes compacted, reducing the porosity.
そこで本考案は、排水溝の側壁に、きわめて簡
単な庇を設けるだけで、集水孔周囲の土砂が締る
ことを防止し、集水機能を保持する排水溝を提供
せんとしたものであり、その要旨は適数個の集水
孔を穿設した排水溝の側壁において、該集水孔列
の上側と下側に、庇を延設し、さらに排水溝の側
壁上部から各集水孔までに導水溝を刻設したこと
にある。 Therefore, the present invention aims to provide a drainage ditch that maintains its water collection function by preventing the earth and sand around the water collection hole from compacting by simply installing an extremely simple eave on the side wall of the drainage ditch. The gist of this is that on the side wall of a drainage ditch with an appropriate number of water collection holes, eaves are extended above and below the row of water collection holes, and each water collection hole is opened from the top of the side wall of the drainage ditch. This is due to the fact that water guide grooves were carved in the area.
次に本考案を図面に示した実施例で説明する。 Next, the present invention will be explained with reference to embodiments shown in the drawings.
鉄筋コンクリート製の排水溝１の側壁２の下方
部に集水孔３を穿設し、該集水孔３に雨水等の浸
透水を導くための、導水溝４を刻設し、また該集
水孔３列の上側、下側に庇５，５′を突設し、さ
らに各溝体の接合部６がずれないように、接合部
６は印ろうチイプにしたり、楔を挿入したりし各
溝体の接合を、確実なものとする。 A water collection hole 3 is bored in the lower part of the side wall 2 of the reinforced concrete drain 1, and a water guide groove 4 is carved to guide percolated water such as rainwater to the water collection hole 3. Eaves 5 and 5' are provided protruding above and below the three rows of holes, and in order to prevent the joints 6 of each groove body from shifting, the joints 6 are made of stubs or wedges are inserted. To ensure the joining of groove bodies.
このように集水機能を持たせた排水溝１は、集
水孔のまわりの土砂の空隙率がきわめて重要であ
るが、施工時に、埋め土１３を踏み固めてしま
い、空隙率を減少させて、集水機能を低下させて
しまうことがよくみられた。 The porosity of the soil around the water collection hole is extremely important for the drainage ditch 1 that has a water collection function as described above, but during construction, the fill soil 13 is compacted and the porosity is reduced. , it was often seen that the water collection function was reduced.
それを防ぐ作用を果すのが、集水孔の上側に設
けられた庇５である。 The eaves 5 provided above the water collection holes serve to prevent this.
このように一見簡単な庇を設けるだけで、埋め
戻し土の集水孔付近の土砂に、適度な空隙を与
え、それが年月が経ても、その空隙率を維持させ
る機能を持つことが、長年の実験の結果より知得
したのである。以下実験例を図示する。 Just by installing a seemingly simple eave like this, it creates a suitable amount of porosity in the soil near the water collection hole in the backfill soil, and it has the ability to maintain that porosity even over time. This was learned from years of experimentation. An experimental example is illustrated below.
排水性のあまり良くない圃場の土を従来の排水
溝を使つて埋め戻したときの透水係数が8.3×
10-5cm／ｓでそのときの集水孔１箇所からの集水
量がせいぜい50c.c.／hrであつたものが、本考案の
庇を設けた排水溝の場合には、集水孔のまわりの
土の浸透係数が4.6×10-3cm／ｓで、集水量950
c.c.／hrを確保することができた。 When field soil with poor drainage is backfilled using conventional drainage ditches, the hydraulic conductivity is 8.3×
10 -5 cm/s, the amount of water collected from one water collection hole at that time was at most 50c.c./hr, but in the case of the drainage ditch with the eaves of the present invention, the amount of water collected from one water collection hole is The permeability coefficient of the surrounding soil is 4.6×10 -3 cm/s, and the water collection capacity is 950.
We were able to secure cc/hr.
ところで、きわめて排水性の悪い土質たとえば
透水係数が10-6cm／ｓ以下の粘土質の場合には、
集水パイプ７や集水ネツト８をこの上下庇間に装
着し、集水能力を確保することもできる。 By the way, in the case of soil with extremely poor drainage, such as clay with a hydraulic conductivity of 10 -6 cm/s or less,
A water collection pipe 7 or a water collection net 8 can be installed between the upper and lower eaves to ensure water collection capacity.
その際、砕石９や、モミガラ１０等を用いて
も、十分にその機能を果し、経済的にも、きわめ
て安価にできる。 In this case, even if crushed stone 9, rice husk 10, etc. are used, the function can be sufficiently performed and it can be done economically at a very low cost.

できる。 Furthermore, in places where the soil has relatively low permeability and there is a local amount of spring water, it is also effective to attach a sand mat 11 made of coconut fiber or the like. When applying this type of auxiliary construction method, especially the lower eaves 5'
This can serve as a support and make installation and installation easier.
逆に透水性は良いのだが、粘性の低い土質の場

よつて微粒子が洗い出されて空隙ができ、安定し
た導水路となり、集水作用が円滑に持続する利点
を有するものである。 On the other hand, if the soil has good water permeability but low viscosity, the surrounding earth and sand will flow into the drainage ditch when water is collected and obstruct the flow in the drainage ditch, so a filter 12 to prevent sand outflow is provided. Sometimes.
Overall, the water collection hole 3 is oriented internally and slightly upward to prevent soil and sand from flowing into it. (Refer to Figure 7) The present invention further has water guide grooves 4 carved from the upper part of the side wall of the drain to each water collection hole. The backfill soil around the area is gradually consolidated, preventing the voids from being blocked, and at the same time, before the consolidation phenomenon occurs, the fine particles are washed out by seepage water, spring water, etc., and the voids are closed. This has the advantage that it becomes a stable water conduit, and the water collecting action continues smoothly.
以上のように、きわめて簡単な庇を集水孔の上

大きな効果を奏するのである。 As mentioned above, by installing extremely simple eaves above and below the water collection hole, the porosity of the backfill soil is secured, and in addition, it is possible to install pipes or nets when the soil has extremely poor drainage conditions. This makes it easy and reliable, and prevents mats from shifting or peeling off when installing in areas with a large amount of spring water.Furthermore, by providing a water guide groove, it is easy to drain water that seeps during rain. This has extremely great effects, such as draining water.
