Description

本発明は、路面上の雨水を流入させるための蓋装置に関するものである。   The present invention relates to a lid device for flowing rainwater on a road surface.

一般的な車道においては、雨天時の雨水等が速やかに車道から排出されるように、道路中央部から歩道に向けて緩やかな下り勾配が付けられ、車道と歩道との境界に側溝が設置されている。また、道路を横切るように横断側溝が設置されている場合がある。これらの側溝の上方には、路面上の雨水を側溝内に流入させるための蓋装置が設置されている。このような蓋装置は、長方形をした周縁枠の内側を複数の格子部材で縦横に区画することによって複数の貫通孔を全面的に配列した格子状の金属製の蓋（グレーチング）が周知となっている。   In general roadways, a gentle downward slope is added from the center of the road toward the sidewalk so that rainwater, etc. in rainy weather is quickly discharged from the roadway, and a gutter is installed at the boundary between the roadway and the sidewalk. ing. In addition, there are cases where a transverse ditch is installed so as to cross the road. Above these side grooves, a lid device is installed for allowing rainwater on the road surface to flow into the side grooves. In such a lid device, a grid-like metal lid (grating) in which a plurality of through holes are arranged in a whole manner by dividing the inside of a rectangular peripheral frame vertically and horizontally by a plurality of grid members is well known. ing.

しかしながら、グレーチングは直交する格子部材を縦横均等に全面的に配置しただけのものであり、雨水の流れ方向や雨水の流入容易性等を考慮したものではないため、実際の道路に設置した場合、雨水が格子部材に衝突することにより、側溝内に流入しにくく、雨水の集水能力が低いという問題があった。また、格子部材が人や車両等の進行方向に沿って直線状に配置されているため、歩行者が足を載せたときに滑って転倒したり、自転車やバイクがその上を通過するときタイヤが滑り、バランスを崩したり転倒したりするおそれがあった。   However, since the grating is simply arranged vertically and horizontally across the lattice members that are orthogonal, and does not consider the flow direction of rainwater or the ease of inflow of rainwater, etc., when installed on an actual road, When the rain water collides with the lattice member, there is a problem that it is difficult for the rain water to flow into the side groove and the rain water collecting ability is low. Also, since the lattice members are arranged linearly along the direction of travel of people, vehicles, etc., tires when the pedestrian slips and falls when a pedestrian puts his foot on it, or when a bicycle or motorcycle passes over it May slip and lose balance or fall.

滑りの防止を図った滑り止めつきグレーチングが特許文献１に記載されている。しかしながら、特許文献１のグレーチングは、雨水の集水能力の点で問題を残したままである。   Patent Document 1 discloses a non-slip grating that prevents slipping. However, the grating of Patent Document 1 still has a problem in terms of the ability to collect rainwater.

特開２０００−２７２７８号公報JP 2000-27278 A

請求項３の発明では、請求項１又は２の発明において、前記凸部上面の高さが前記外縁枠上面と同一高さに形成されていることを特徴としている。 According to a second aspect of the present invention, in the first aspect of the invention, the convex portions in the convex portion row adjacent to the convex portions in the convex portion row are displaced from each other in the longitudinal direction of the top plate portion. It is characterized by.
According to a third aspect of the present invention, in the first or second aspect of the present invention, the height of the upper surface of the convex portion is formed at the same height as the upper surface of the outer edge frame.

請求項４の発明では、請求項１〜３のいずれかの発明において、前記流水口の開口幅は前記天板部の外縁枠側が最も大きいことを特徴としている。
請求項５の発明では、請求項１〜４のいずれかの発明において、前記天板部の裏面に設けられ、前記天板部の短手方向に沿って配された補強リブと、該補強リブが配された位置における前記天板部の表面に設けられ、前記流水口に連通する窪み部とをさらに備えたことを特徴としている。 The invention of claim 4 is characterized in that, in the invention of any one of claims 1 to 3, the opening width of the water flow port is the largest on the outer edge frame side of the top plate portion.
According to a fifth aspect of the present invention, in any one of the first to fourth aspects of the present invention, a reinforcing rib provided on the back surface of the top plate portion and arranged along the short direction of the top plate portion, and the reinforcing rib It is provided in the surface of the top plate part in the position where it was arranged, and further provided with the hollow part connected to the flowing water mouth.

請求項１の発明によれば、天板部の断面が両端に向けて下り傾斜となる略円弧状であるため、蓋材の長辺側から流入する雨水は天板部上面の傾斜を上るようにして流れる。このため、雨水の流れが弱まり、天板部を越えて流れることを防止できる。そして雨水は、天板部に穿設された流水口に流入される。また、天板部には凸部が複数備わるため、天板部上を流れる雨水をこれに衝突させ、雨水の流れを弱めることができ、流水口に流入させ易くすることができる。また、凸部により、蓋装置上を人や車両が通過する際のスリップ防止を図ることができる。また、凸部は流水口に沿って配設されているため、流水口に雨水を流入させるためのガイドとして作用させることができる。   According to the first aspect of the present invention, since the cross section of the top plate portion has a substantially arcuate shape that is inclined downward toward both ends, rainwater flowing from the long side of the lid member rises on the top surface of the top plate portion. And flow. For this reason, the flow of rainwater is weakened and can be prevented from flowing beyond the top plate. And rainwater flows in into the flowing water hole drilled in the top plate part. Moreover, since the top plate part is provided with a plurality of convex portions, it is possible to make rainwater flowing on the top plate portion collide with this, weaken the flow of rainwater, and easily flow into the water outlet. Further, the convex portion can prevent slippage when a person or vehicle passes over the lid device. Moreover, since the convex part is arrange | positioned along the water flow port, it can be made to act as a guide for making rainwater flow in into a water flow port.

請求項２の発明によれば、凸部列における凸部は、隣接する凸部列の凸部と天板部の長手方向においてずれて配置されている。このため、雨水が手前の流水口を越えたとしても凸部に衝突するので、次列の流水口に雨水を流入させることができる。   According to invention of Claim 2, the convex part in a convex part row | line | column is shifted | deviated and arrange | positioned in the longitudinal direction of the convex part of an adjacent convex part row | line | column, and a top-plate part. For this reason, even if rainwater exceeds the water outlet in front, the rainwater can flow into the water outlet in the next row because it collides with the convex portion.

請求項３の発明によれば、凸部上面高さが外縁枠上面と同一高さに形成され、天板部上面両端が外縁枠上面から外縁枠の内側面を介して下がった状態に形成される。このため、天板部上に流入した雨水が再び天板部上から流出することを抑制し、効率よく雨水を流水口に流入させることができる。また、凸部上面が同一高さにあるため、蓋装置上を車両が通行したり、あるいは歩行者が歩行したりした際に、違和感なく通過することができる。   According to the invention of claim 3, the height of the upper surface of the convex portion is formed to be the same height as the upper surface of the outer edge frame, and both ends of the upper surface of the top plate portion are formed in a state of being lowered from the upper surface of the outer edge frame via the inner surface of the outer edge frame. The For this reason, it can suppress that the rain water which flowed in on the top-plate part flows out from the top-plate part again, and can make rain water flow in into a flow outlet efficiently. Moreover, since the convex part upper surface is the same height, when a vehicle passes over the lid | cover apparatus or a pedestrian walks, it can pass without discomfort.

請求項４の発明によれば、流水口の開口幅は、流水口列でみると天板部の外縁枠側が最も大きい。このため、天板部の長辺側の流水口列に配された幅広の流水口を用い、雨水を効率よく流水口に流入させることができる。   According to the invention of claim 4, the opening width of the flowing water port is the largest on the outer edge frame side of the top plate portion when viewed from the flowing water port array. For this reason, rainwater can be efficiently made to flow into a water flow port using the wide water flow port distribute | arranged to the water flow port row | line | column of the long side of a top-plate part.

請求項５の発明によれば、天板部の裏面に補強リブが設けられ、天板部の表面に流水口に連通する窪み部がさらに設けられるので、補強リブがあるために流水口を設けられない位置においても、窪み部により効率よく雨水を流水口に案内することができる。また、補強リブと流水口が交差することがあっても、補強リブは天板部の裏面に設けられているため、補強リブ上面は流水口の下面に位置することになり、流水口への雨水流入の妨げにならない。   According to the fifth aspect of the present invention, the reinforcing rib is provided on the back surface of the top plate portion, and the recess portion communicating with the flowing water port is further provided on the surface of the top plate portion. Even at a position where it is not possible, rainwater can be efficiently guided to the water outlet by the depression. In addition, even if the reinforcing rib and the water outlet intersect, the reinforcing rib is provided on the back surface of the top plate, so the upper surface of the reinforcing rib is located on the lower surface of the water outlet, Does not interfere with rainwater inflow.

本発明に係る蓋装置の平面図である。It is a top view of the lid device concerning the present invention. 図１のＡ−Ａ断面図である。It is AA sectional drawing of FIG. 本発明に係る蓋装置を用いた側溝の概略図である。It is the schematic of the side groove | channel using the cover apparatus which concerns on this invention.

図１に示す本発明に係る蓋装置１の例では、蓋材２と、流水口３と、凸部４とを有している。蓋材２は、天板部２ａと、側板部２ｂと、フランジ部２ｃと、外縁枠２ｄとを有している。蓋装置１の材質は例えばダクタイル鋳鉄である。蓋装置１は、後述するように、地中に埋設された側溝本体の上側開口部を覆うものである。天板部２ａは、図２を参照すれば明らかなように、天板部２ａの短手方向において断面が両端に向けて下り傾斜となる略円弧状に形成されている。天板部２ａは、蓋材２を側溝本体１３に取り付けたときに、路面に露出する部分である。天板部２ａは、平面視で略矩形形状をなしている。側板部２ｂは、天板部２ａの両側縁から連続して下側に延びている。フランジ部２ｃは、側板部２ｂの下端から外方に延び、天板部２ａと段差を有して突出している。外縁枠２ｄは、天板部２ａの外周縁に立設し、その内側面８が下方に傾斜して天板部２ａに連なっている。   The example of the lid device 1 according to the present invention shown in FIG. 1 includes a lid member 2, a water flow port 3, and a convex portion 4. The lid member 2 includes a top plate portion 2a, a side plate portion 2b, a flange portion 2c, and an outer edge frame 2d. The material of the lid device 1 is, for example, ductile cast iron. The lid | cover apparatus 1 covers the upper side opening part of the gutter body embed | buried under the ground so that it may mention later. As is apparent from FIG. 2, the top plate portion 2a is formed in a substantially arc shape whose cross section is inclined downward toward both ends in the short direction of the top plate portion 2a. The top plate portion 2 a is a portion exposed to the road surface when the lid member 2 is attached to the side groove main body 13. The top plate portion 2a has a substantially rectangular shape in plan view. The side plate portion 2b extends continuously downward from both side edges of the top plate portion 2a. The flange portion 2c extends outward from the lower end of the side plate portion 2b and protrudes with a step from the top plate portion 2a. The outer edge frame 2d is erected on the outer peripheral edge of the top plate portion 2a, and the inner side surface 8 is inclined downward and is continuous with the top plate portion 2a.

天板部２ａには、天板部２ａを貫通する流水口３が穿設されている。この流水口３は、天板部２ａの長手方向に沿った開口長さ３ａと、天板部２ａの短手方向に沿った開口幅３ｂとを有している。開口長さ３ａは、開口幅３ｂよりも長く、流水口３は長尺である。流水口３は天板部２ａの長手方向に沿って断続的に複数設けられ、流水口列５を形成している。この流水口列５は、天板部２ａに複数列設けられている。天板部２ａ上に流れ込んだ雨水は、この流水口３に流入する。このとき、天板部２ａは断面が両端に向けて下り傾斜となる略円弧状であるため、蓋材２の長辺側から流入する雨水は天板部２ａ上面の傾斜を上るようにして流れる。このため、雨水の流れが弱まり、天板部２ａを越えて雨水が流れることを防止し、効率よく雨水を流水口３に流入させることができる。また、各流水口列５の流水口３は、天板部２ａの長手方向においてずれて配置されている。これにより、流水口３への雨水の流入効率をさらに向上させることができる。   In the top plate portion 2a, a flowing water port 3 penetrating the top plate portion 2a is formed. The flowing water port 3 has an opening length 3a along the longitudinal direction of the top plate portion 2a and an opening width 3b along the short direction of the top plate portion 2a. The opening length 3a is longer than the opening width 3b, and the flowing water port 3 is long. A plurality of water outlets 3 are provided intermittently along the longitudinal direction of the top plate portion 2 a to form a water inlet array 5. A plurality of the water flow outlet rows 5 are provided in the top plate portion 2a. Rainwater that has flowed onto the top plate portion 2 a flows into the water outlet 3. At this time, since the top plate portion 2a has a substantially arc shape whose cross section is inclined downward toward both ends, rainwater flowing in from the long side of the lid member 2 flows so as to rise on the top surface of the top plate portion 2a. . For this reason, the flow of rainwater is weakened, it is possible to prevent rainwater from flowing over the top plate portion 2a, and rainwater can efficiently flow into the water outlet 3. Moreover, the water flow port 3 of each water flow port row | line | column 5 has shifted | deviated and arrange | positioned in the longitudinal direction of the top-plate part 2a. Thereby, the inflow efficiency of the rainwater to the flowing water port 3 can be further improved.

また、流水口列５のうち、少なくとも一の列は外縁枠２ｄの内側面８の下端に沿って配されている。そして、この外縁枠２ｄに沿った流水口列５の流水口３の開口幅３ｂは、最も大きく形成されている（例えば１３ｍｍ）。また、天板部２ａの短手方向の中心軸線側にある流水口列５の流水口３の開口幅３ｂが最も小さく形成されている（例えば８ｍｍ）。このため、天板部２ａの長辺側の流水口列５に配された幅広の流水口３を用い、雨水を効率よく流水口３に流入させることができる。   In addition, at least one of the flowing water port rows 5 is disposed along the lower end of the inner side surface 8 of the outer edge frame 2d. And the opening width 3b of the water flow port 3 of the water flow port row | line | column 5 along this outer edge frame 2d is formed the largest (for example, 13 mm). Moreover, the opening width 3b of the water flow port 3 of the water flow port row | line | column 5 in the center axis line side of the transversal direction of the top-plate part 2a is formed the smallest (for example, 8 mm). For this reason, rainwater can be efficiently made to flow into the water flow port 3 using the wide water flow port 3 arranged in the flow port array 5 on the long side of the top plate portion 2a.

天板部２ａ及び外縁枠２ｄの内側面８には、凸部４が設けられている。凸部４は、流水口３に沿って設けられている。凸部４は、天板部２ａの長手方向に沿って断続的に複数配され、凸部列６を形成している。この凸部４により、天板部２ａ上を流れる雨水をこれに衝突させ、雨水の流れを弱くすることができ、流水口３に流入させ易くすることができる。また、凸部４により、蓋装置１上を人や車両が通過する際のスリップ防止を図ることができる。また、凸部４は流水口３に沿って配設されているため、流水口３に雨水を流入させるためのガイドとして作用させることができる。   Convex portions 4 are provided on the inner surface 8 of the top plate portion 2a and the outer edge frame 2d. The convex portion 4 is provided along the flowing water port 3. A plurality of the convex portions 4 are intermittently arranged along the longitudinal direction of the top plate portion 2 a to form a convex portion row 6. By this convex portion 4, rainwater flowing on the top plate portion 2 a can collide with this, the flow of rainwater can be weakened, and it can be made easy to flow into the water outlet 3. Further, the protrusion 4 can prevent slipping when a person or vehicle passes over the lid device 1. Moreover, since the convex part 4 is arrange | positioned along the water flow port 3, it can be made to act as a guide for making rainwater flow in into the water flow port 3. FIG.

また、凸部列６における凸部４は、隣接する凸部列６の凸部４と天板部２ａの長手方向においてずれて配置されている。このため、雨水が長辺側の外縁枠２ｄから流入し、雨水が流水口３を越えて流れたとしても、この雨水は凸部４に衝突するので、戻って流水口３に流入させることができる。また、凸部４の上面の高さが外縁枠２ｄの上面の高さと同一高さに形成され、天板部２ａの上面は外縁枠２ｄの上面から外縁枠２ｄの内側面８を介して下がった位置に形成される。このため、天板部２ａ上に流入した雨水が再び天板部２ａから流出することを抑制し、効率よく雨水を流水口３に流入させることができ、蓋装置１上を車両が通行したり、あるいは歩行者が歩行した際に、凸部４の上面がそろっているため、違和感なく通過することができる。凸部４の上面高さを揃えるため、天板部２ａの両端付近の低い位置に配される凸部４は小径及び大径の円柱部材を２段重ねて形成されている。一方、天板部２ａの頂上面２４及び外縁枠２ｄの内側面８のような天板部２ａの両端付近よりも高い位置に配される凸部４は１段の円柱部材で形成されている。なお、凸部４の最上面は例えば直径５ｍｍであり、隣接する凸部４の中心間の距離は例えば２５ｍｍで形成されており、流水口３の配置により、１３．６３ｍｍ〜３３．８７ｍｍの範囲で形成される箇所もある。   Moreover, the convex part 4 in the convex part row | line | column 6 has shifted | deviated and arrange | positioned in the longitudinal direction of the convex part 4 of the adjacent convex part row | line | column 6, and the top-plate part 2a. For this reason, even if rainwater flows in from the outer edge frame 2d on the long side and the rainwater flows over the water flow port 3, the rain water collides with the convex portion 4, so that it can return and flow into the water flow port 3. it can. Further, the height of the upper surface of the convex portion 4 is formed to be the same as the height of the upper surface of the outer edge frame 2d, and the upper surface of the top plate portion 2a is lowered from the upper surface of the outer edge frame 2d through the inner side surface 8 of the outer edge frame 2d. Formed at different positions. For this reason, it is possible to prevent rainwater that has flowed onto the top plate portion 2a from flowing out of the top plate portion 2a again, and to efficiently cause rainwater to flow into the water outlet 3 so that the vehicle passes over the lid device 1. Or, when the pedestrian walks, since the upper surfaces of the convex portions 4 are aligned, the pedestrian can pass without a sense of incongruity. In order to make the upper surface height of the convex part 4 uniform, the convex part 4 arranged at a low position near both ends of the top plate part 2a is formed by stacking two small-diameter and large-diameter cylindrical members. On the other hand, the convex portions 4 arranged at positions higher than the vicinity of both ends of the top plate portion 2a, such as the top surface 24 of the top plate portion 2a and the inner side surface 8 of the outer edge frame 2d, are formed of a single column member. . In addition, the uppermost surface of the convex part 4 is 5 mm in diameter, for example, and the distance between the centers of the adjacent convex part 4 is formed at 25 mm, for example, and it is the range of 13.63 mm-33.87 mm by arrangement | positioning of the water flow port 3. There is also a place formed by.

図２を参照すれば明らかなように、天板部２ａの裏面には、天板部２ａの短手方向に沿って配された補強リブ７が設けられている。そして、図１に示すように、補強リブ７が配された位置における天板部２ａの表面には、流水口３に連通する窪み部９が設けられている。このように、天板部２ａの裏面に補強リブ７が設けられ、天板部２ａの表面には流水口３に連通する窪み部９がさらに設けられるので、補強リブ７があるために流水口３を設けられない位置においても、窪み部９により効率よく雨水を流水口３に案内することができる。また、補強リブ７と流水口３が交差することがあっても、補強リブ７は天板部２ａの裏面に設けられているため、補強リブ７の上面は流水口３の下面に位置することになり、流水口３への雨水流入の妨げにならない。なお、図の例では、天板部２ａの長手方向の裏面に沿った位置にも補強リブ１０が配設されている。   As is apparent from FIG. 2, reinforcing ribs 7 are provided on the back surface of the top plate portion 2a along the short direction of the top plate portion 2a. And as shown in FIG. 1, the hollow part 9 connected to the water flow port 3 is provided in the surface of the top-plate part 2a in the position where the reinforcement rib 7 was distribute | arranged. In this way, the reinforcing rib 7 is provided on the back surface of the top plate portion 2a, and the recess portion 9 communicating with the flowing water port 3 is further provided on the surface of the top plate portion 2a. Even in a position where 3 is not provided, rainwater can be efficiently guided to the water outlet 3 by the recess 9. Even if the reinforcing rib 7 and the water flow port 3 may intersect, the upper surface of the reinforcing rib 7 is located on the lower surface of the water flow port 3 because the reinforcing rib 7 is provided on the back surface of the top plate portion 2a. And does not hinder the inflow of rainwater into the water outlet 3. In the example shown in the figure, the reinforcing ribs 10 are also disposed at positions along the back surface in the longitudinal direction of the top plate portion 2a.

図２に示すように、側板部２ｂには雨水を流入させるための貫通孔１１が穿設されている。この貫通孔１１は、蓋装置１を設置した周囲の舗装が透水性の場合に、透水した雨水を取り込むためのものである。また、側板部２ｂには舗装を掘削して埋め戻す際の目印としての段差部１２が設けられている。この段差部１２の代わりに線を描いてもよい。   As shown in FIG. 2, a through hole 11 for allowing rainwater to flow is formed in the side plate portion 2b. This through-hole 11 is for taking in the rainwater which permeate | transmitted when the surrounding pavement which installed the cover apparatus 1 is water-permeable. Further, the side plate portion 2b is provided with a step portion 12 as a mark when excavating and refilling the pavement. A line may be drawn instead of the step portion 12.

上述したような蓋装置１を側溝に用いると、図３に示すように、天板部２ａの上面が路面に露出される。この設置方法は、以下に示すようにして行われる。まず、上側が開放された断面Ｕ字形状であって、地中に埋設された長尺の側溝本体１３に対し、アンカーボルト１６を設置する。具体的には、アンカーボルト１６は、側溝本体１３を形成する両側の側壁１３ａの上部にそれぞれ形成された孔に埋め込んで設置される。これにより、アンカーボルト１６は側壁１３ａの上端面からそれぞれ上方に延びるように立設される。次に、アンカーボルト１６のそれぞれに高さ調整部材１４を螺合する。高さ調整部材１４は、アンカーボルト１６に沿って螺合しながら上下動可能である。フランジ部２ｃに設けられたマーク１８（図１参照）を目印としてフランジ２ｃを貫通する外側の４箇所の挿通孔１９（図１参照）にアンカーボルト１６を挿通し、ナット２０にて固定する。このとき、高さ調整部材１４により、フランジ部２ｃの高さを調節することができる。したがって、蓋材２を傾かせることができるので、流路の傾斜が道路の傾斜と異なる場合に、道路の傾斜にあわせて天板部２ａを傾かせる傾斜施工を容易に行うことができる。そして、フランジ部２ｃと側壁１３ａの上端面との間にモルタル１５を充填する。この充填時、モルタル１５が漏れないように側壁１３ａの内側は内板１７で押さえられ、外側は外板（不図示）で押さえられる。   When the lid device 1 as described above is used for the side groove, the top surface of the top plate portion 2a is exposed to the road surface as shown in FIG. This installation method is performed as follows. First, an anchor bolt 16 is installed on a long side groove main body 13 which has a U-shaped cross section with an open upper side and is buried in the ground. Specifically, the anchor bolts 16 are installed by being embedded in holes formed in the upper portions of the side walls 13a on both sides forming the side groove main body 13, respectively. Accordingly, the anchor bolts 16 are erected so as to extend upward from the upper end surface of the side wall 13a. Next, the height adjusting member 14 is screwed into each of the anchor bolts 16. The height adjusting member 14 can move up and down while being screwed along the anchor bolt 16. The anchor bolts 16 are inserted into four outer insertion holes 19 (see FIG. 1) that penetrate the flange 2c using the marks 18 (see FIG. 1) provided on the flange portion 2c as marks, and are fixed with nuts 20. At this time, the height of the flange portion 2 c can be adjusted by the height adjusting member 14. Therefore, since the lid member 2 can be tilted, when the channel is inclined differently from the road, the slope construction for tilting the top plate portion 2a according to the road can be easily performed. And the mortar 15 is filled between the flange part 2c and the upper end surface of the side wall 13a. At the time of filling, the inner side of the side wall 13a is pressed by the inner plate 17 and the outer side is pressed by the outer plate (not shown) so that the mortar 15 does not leak.

モルタル固化後、まず土砂２１を埋め戻し、その上側をアスファルト等の舗装材２２で舗装する。このような蓋装置１を有する側溝２３は、側溝本体１３が地中に埋設され、路面に露出しているのは側溝本体１３に一体に固定された蓋材２の天板部２ａであるため、車両の通行によってガタつきが発生することを抑制することができる。   After the mortar is solidified, the earth and sand 21 are first backfilled, and the upper side thereof is paved with a paving material 22 such as asphalt. In the side groove 23 having such a lid device 1, the side groove main body 13 is buried in the ground, and it is the top plate portion 2 a of the lid member 2 that is integrally fixed to the side groove main body 13 that is exposed to the road surface. It is possible to prevent the rattling from occurring due to the passage of the vehicle.
