Description

本発明は、道路の長さ方向または横断方向に配置される排水用水路の構築に使用される水路用ブロックに関するものである。 The present invention relates to a block for a water channel used for construction of a water channel for drainage disposed in a length direction or a transverse direction of a road.

従来の普通の道路構造は、道路表面にアスファルトなどの不透水性の舗装層を形成し、道路の長さ方向または幅方向に排水用水路を設置したものであり、道路表面を流れて来た雨水は、水路用ブロックの上部壁版の長さ方向の開口部に嵌められたクレーチングを通して、水路用ブロックの流水部に導かれている。 The conventional ordinary road structure is formed by forming an impervious pavement layer such as asphalt on the road surface and installing drainage waterways in the length direction or width direction of the road, and rainwater flowing on the road surface Is guided to the flowing water portion of the water channel block through the crutch fitted in the opening in the length direction of the upper wall plate of the water channel block.

これに対して、近年は雨水を地中に還流させる必要性が唱えられ、透水性の舗装が行われるようになった。しかしながら、透水性舗装層における水の浸透速度には一定の限界があるため、多量の雨が降るときには、浸透待ちの雨水が道路表面に滞留し、車両のスリップ事故の原因となるばかりか、通行車両が水を跳ね上げ、歩行者にとっても通行し難い状態となる。そのため、透水舗装道路においても道路の長さ方向または横断方向に排水用水路が設置されている。 On the other hand, in recent years, the necessity of returning rainwater to the ground has been advocated, and permeable pavement has come to be performed. However, since there is a certain limit to the water penetration rate in the permeable pavement layer, when a large amount of rain falls, rainwater awaiting penetration penetrates the road surface, causing not only vehicle slip accidents but also traffic. The vehicle splashes water, making it difficult for pedestrians to pass. For this reason, drainage waterways are also installed in the length direction or crossing direction of roads on permeable paved roads.

非透水性舗装道路と透水性舗装道路のいずれにおいても、排水用水路の最適な設置形態としては、水路用ブロックは、上部壁版の上面が舗装層の上面の延長上に来るように配置されるべきなのであるが、施工場所の個別的状況やバリヤフリー化工事等においては、舗装層の上面が水路ブロックの上部壁版の上面より相当上に来ることが最近多く発生している。 For both non-permeable and permeable paved roads, the best way to install a drainage channel is to place the channel block so that the upper surface of the upper wall slab is an extension of the upper surface of the paving layer. Although it should be, in the individual situation of the construction site and barrier-free construction, etc., it has recently occurred that the upper surface of the pavement layer is considerably higher than the upper surface of the upper wall plate of the channel block.

このような場合には、水路用ブロックの前記開口部の両側にアングル鋼材をボルト固定し、一方の側のアングル鋼材の起立板部によって舗装層の外縁部を画定し、他方の側のアングル鋼材の起立板部によって歩車道境界用ブロックの据付位置を画定し、両方のアングル鋼材の間にグレーチングを嵌めこむことが行なわれている。そして、舗装層が透水性であるときには、アングル鋼材の起立板部に多数の貫通孔を設け、舗装層の内部を浸透して来た水を前記貫通孔より前記開口部に導くことが行なわれている(例えば特許文献1参照)。 In such a case, the angle steel material is bolted to both sides of the opening of the water channel block, the outer edge portion of the pavement layer is defined by the upright plate portion of the angle steel material on one side, and the angle steel material on the other side. The standing position of the pedestrian boundary block is defined by the upright plate portion, and the grating is fitted between the two angle steel materials. When the pavement layer is water permeable, a large number of through holes are provided in the upright plate portion of the angle steel material, and the water that has permeated the inside of the pavement layer is guided to the opening through the through holes. (For example, refer to Patent Document 1).

しかしながら、ボルト固定するアングル鋼材を使用する方式では、アングル鋼材の他に多数本のボルトと、該ボルトがねじ込まれるナット型インサートと、グレーチングを必要とするため、これら金具の材料費が高価なものとなる上に、多数のナット型インサートの型枠への定着作業、多数のボルトの締め付け作業を必要とするため、加工・取付の労賃コストも高価なものとなっている。透水性舗装層を対象とする場合には、アングル鋼材への穿孔作業も必要であるため、労賃コストは更に増加した。 However, in the method using angle steel material to fix the bolt, in addition to the angle steel material, a large number of bolts, a nut type insert into which the bolt is screwed, and a grating are required. In addition, fixing work for a large number of nut-type inserts on a mold and tightening work for a large number of bolts are required, so that labor costs for processing and mounting are also expensive. When the target is a permeable pavement layer, drilling work on angle steel is also necessary, and labor costs have increased further.

特許第2676493号公報Japanese Patent No. 2676493

したがって、本発明の課題は、舗装層上面に対して水路用ブロックの上面が低い位置にあるような設置場所においても、材料費や労賃コストをいたずらに増大させることなく、必要十分な排水機能を付与できるようにすることである。 Therefore, an object of the present invention is to provide a necessary and sufficient drainage function without unnecessarily increasing the material cost and labor cost even in an installation place where the upper surface of the water channel block is located at a position lower than the upper surface of the pavement layer. It is to be able to grant.

There is nothing to do. Further, when the water-permeable pavement layer 11 is applied to the other divided section, the upright plate portion 4 b of the second frame plate 4 is not distorted and deformed in the direction of the first frame plate 3.

互いに平行に接合されたアングル型材製の第1枠板3と第2枠板4の各起立板部3b,4bは、鉛直方向に沿って配置されているため、両者間の排水用間隙13に落ち込んだゴミは起立板部3b,4bに引っかかり難く、目詰まりしたゴミによって排水性能を低下させることがない。 Since the upright plate portions 3b and 4b of the first frame plate 3 and the second frame plate 4 that are joined in parallel with each other are arranged along the vertical direction, the drainage gap 13 between them is disposed. The fallen dust is not easily caught by the upright plate portions 3b and 4b, and the drainage performance is not deteriorated by the clogged dust.
