Description

  The present invention relates to a gutter embedded in a side of a road.

  A general side groove is composed of a side groove main body and a lid portion, and the side groove main body is formed with a substantially U-shaped cross section and a lid portion is provided near the upper opening end of the side groove main body. Met. In this case, the lid receiving portion is formed by widening the vicinity of the upper opening portion of the opposing side wall constituting the side groove main body, and the lid portion is placed on the lid receiving portion.

  Since the side groove as described above is configured to place the lid portion near the upper opening of the side groove body, a slight gap is generated between the lid receiving portion and the lid portion, and the adjacent lid portions. Also, there was a gap between them. Therefore, when the vehicle passes over the lid portion, the lid portion moves slightly and the gap portion collides. When the collision sound at that time is loud, it is noisy. It was. Further, as described above, due to the collision of the gap portion, the lid portion is subjected to a severe impact, which causes damage to the lid portion. In addition, a large force is applied when the vehicle or the like passes, which causes the unstable lid portion to vibrate and also causes detachment from the side groove body.

Therefore, in order to solve such problems, as a conventional technique, a lid hanging portion is provided above the inner wall of the U-shaped side groove main body, and the lid portion has a lower surface side that bulges to the back side thereof. The bulging portion is configured, and inclined portions are provided on both sides of the lower surface side bulging portion, and the distance between the facing corner portions of the lid hanging portions provided on both inner walls of the side groove main body There was a configuration in which one of the inclined portions was in contact with one corner of the side groove body and the lid portion was fixed by narrowing the interval between the inclined portions on both sides of the lower surface side bulge portion ( Patent Document 1).

  However, in the above prior art, when a biased load is applied to the lid portion, the lid portion is prevented from moving in the lateral direction. Although it can be avoided by the fact that the part constituting the both side walls of the main body and the both side ends of the lid can be contacted without any gap, the inclined part of the lower surface side bulging part is the lid hanging part, and according to the inclination The lid portion may move in the vertical direction when a large load acts downward, such as when a heavy object such as a vehicle passes, because the structure has a gap. Then, since the lid portion is not fixed to the side groove main body, the installation state of the lid portion may be changed by the movement of the lid portion in the vertical direction as described above.

  Recently, a side groove block that does not use a lid has been developed, and there is a structure that is constructed integrally with a curbstone or the like (see Patent Document 2). Since it is configured to be very narrow so as not to be derailed, it caused a new problem that it cannot be easily cleaned when various kinds of debris accumulate in the side grooves. .

  The present invention has been made in view of the above-mentioned points, and the object of the present invention is a configuration using a lid portion having a relatively wide opening and a side groove while being a concrete product. It is to provide a side groove that can firmly fix the lid to the main body.

  Accordingly, the present invention is a side groove composed of a side groove body made of concrete and a lid part, and the side groove body has a drainage channel having a substantially rectangular or substantially circular cross-sectional shape and a longitudinal direction above the drainage channel. A side groove body comprising a water collecting groove formed along the water collecting groove and a groove-shaped opening formed by opening an upper portion of the drainage channel along the water collecting groove, and the lid portion The gist of the present invention is a gutter characterized by a lid portion having a substantially wedge-shaped cross section with an upper portion wider than the opening width and a lower portion that can be loosely fitted into the opening. In this case, the lid portion can be configured to be shorter than the unit length of the gutter body. Moreover, it can be set as the opening part end surface which comprises the contact area | region which contact | abuts with a cover part, and the non-contact area | region which does not contact | abut on the end surface of an opening part.

  Further, the present invention is a side groove composed of a side groove body made of concrete and a lid part, and the side groove body has a drainage channel having a substantially rectangular or substantially circular cross-sectional shape and a longitudinal direction above the drainage channel. A side groove body comprising a water collecting groove formed along the water collecting groove and a groove-shaped opening formed by opening an upper portion of the drainage channel along the water collecting groove, and the lid portion is formed on the opening. When engaging, it comprises a contact region that contacts the end face of the opening and a non-contact region that does not contact, and the contact region has an upper part wider than the opening width of the opening, and in the opening. The gist also includes a side groove characterized by a substantially wedge-shaped cross section with a lower part that can be loosely fitted.

  In the above, the opening may be configured such that at least one end surface is formed in an oblique shape, while the lid portion is configured such that at least one side surface is formed in an inclined shape. In this case, the oblique end surface of the opening and the oblique side surface of the lid can be configured with the same inclination angle.

  As described above, according to the present invention, the lid portion is engaged with the opening of the side groove main body in the same state as the wedge, and even if the weight of the vehicle or the like acts on the lid portion, it is easy. Will never change its state. Therefore, even when a vehicle or the like passes, the side groove main body and the lid portion do not collide with each other, thereby preventing the occurrence of a collision sound and eliminating the noise. In addition, as described above, the side groove main body and the lid portion do not collide with each other, so that the lid portion can be prevented from being damaged at the same time, thereby prolonging the service life of the entire side groove. If the lid portion is configured to be short, a portion where the lid portion is not engaged with the opening portion of the side groove main body can be formed, and rainwater or the like flowing into the water collecting groove of the side groove main body can be included in the lid portion engaging portion. It is made to flow into the drainage channel from the opening which is not made and drainage is enabled.

  Moreover, since the opening part of a side groove part main body can be provided sufficiently wide, when cleaning a drainage channel, the tool for cleaning can be inserted in a drainage channel. And although the downward movement of the lid portion is restricted as an effect of the wedge, the lid portion can be moved upward, so that the lid portion can be easily removed during cleaning.

  Furthermore, in the invention in which a non-contact area is provided in the lid, in the non-contact area, a narrow groove is formed between the end surface of the opening and the side surface of the cover, and the narrow groove is a side groove body. Since rainwater that has flowed into the drainage channel is guided to the drainage channel, rainwater and the like can flow down to the drainage channel even when a lid is engaged in the entire opening of the side groove body. It will be possible.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the present embodiment is composed of a gutter body 1 and a lid 2, both of which are composed of concrete. The side groove body 1 is provided with a drainage channel 11, a water collecting groove 12 and an opening 13 all continuously in the longitudinal direction. The lid portion 2 is formed in a wedge shape in cross section, and can be engaged with the opening portion 13 of the side groove main body 1 and can close the opening portion 13. And the said cover part 2 is long enough, and makes the opening part 13 close simultaneously by predetermined length.

  The drainage channel 11 is disposed at substantially the center of the gutter body 1 and has a cross-sectional area enough to allow rainwater or the like to flow down sufficiently. The water collecting groove 12 is configured such that the upper surface of the side groove main body 1 has a concave shape with a predetermined width, and is provided along the longitudinal direction of the drainage channel 11. The opening 13 opens the drainage channel 11 along the water collecting groove 12 and is continuous from the drainage channel 11 to the water collecting groove 12, and has a sufficient width and the drainage channel 11. Is opened. Therefore, when embedding the gutter body 1 on the side of the road, rainwater or the like flowing from the road toward the gutter body 1 once flows into the water collecting groove 12 and then flows into the drainage channel 11 from the opening 13 to be drained. It becomes the composition which is done. Although there are various cross-sectional shapes of the drainage channel 11, in the present embodiment, an example having a substantially circular cross-section will be described.

  Here, the relationship between the opening 13 and the lid 2 will be described in detail. As shown in FIG. 2A, the opening 13 is composed of two diagonal end faces 13a and 13b facing each other. The oblique end faces 13a and 13b are configured such that the width W2 at the lower end is narrower than the width W1 at the upper end. On the other hand, the lid portion 2 having a wedge-shaped cross section is configured such that the side surfaces 21a and 21b engaged with the opening 13 are slanted, and the side surfaces 21a and 21b have the thickness W3 at the uppermost end. In addition to increasing the thickness, the bottom wall thickness W4 is made the thinnest. Further, the thickness W3 at the upper end is thicker than the width W1 at the upper end of the opening 13, and the thickness W4 at the lower end is thinner than the width W2 at the lower end of the opening 13.

  With the above configuration, as shown in FIG. 2B, when the lid portion 2 is engaged with the opening portion 13 of the side groove main body 1, the lower periphery of the lid portion 2 is loosely fitted with the opening portion 13 and the drainage portion 11. On the other hand, on the upper periphery of the lid portion 2, both side surfaces 21 a and 21 b come into contact with the oblique end surfaces 13 a and 13 b of the opening portion 13. Therefore, when the lid portion 2 is pressed down strongly, the lid portion 2 is sandwiched by the opening portion 13, and the lid portion 2 can be stably fixed.

  As described above, in the present embodiment, when the weight of a vehicle or the like acts on the lid portion 2 in a state where the lid portion 2 is engaged with the opening portion 13 of the gutter body 1, the center of the lid portion 2 is affected. When a downward load is applied, both side surfaces 21a and 21b of the lid portion 2 are evenly distributed to the oblique end surfaces 13a and 13b of the opening portion 13, so that the engagement state of the lid portion 2 is There is no change.

  Further, when a biased load is applied to the lid 2, as shown in FIG. 3, only one of the upper edges 22 a and 22 b of the lid 2 (for example, the left side in the figure) Edge 22a) Even if a load is applied, in order for the edge 22a to move downward, the lid 2 must rotate around the opening upper end 14b with which the opposite side surface 21b abuts. Since the thickness of the lid portion 2 is increased upward, it cannot be rotated as described above, and the initial engagement state is maintained.

  In this way, since the engagement state does not change due to the passage of the vehicle or the like, the side groove main body and the lid portion do not collide, and the cause of the collision noise, that is, noise can be eliminated. Further, as shown in the figure, the shape of the lid portion 2 is a vertically long shape different from the conventional one, and thus, even when a vehicle or the like passes, the portion that contacts the wheel of the vehicle or the like is small, and the lid portion It is also possible to prevent a lateral load from acting on 2. Even if a load is applied in the lateral direction, the lid 2 is largely engaged with the opening 13 so that the lid 2 can be prevented from being detached.

  Next, a modified form of the above embodiment will be described. As shown in FIGS. 4A and 4B, the inclined end surfaces 13a and 13b of the opening 13 are inclined at angles different from those of the above embodiment. There is a configured form. In the form shown in FIG. 4A, the inclination angles of the oblique end faces 13 a and 13 b of the opening 13 are made to coincide with the angles of the side surfaces 21 a and 21 b of the lid 2, and the lid 2 is opened to the opening 13. In this state, the entire end faces of the two are in surface contact with each other. According to such surface contact, since they are in close contact with each other over a wide area, they are integrated to improve stability.

  In the form shown in FIG. 4B, the oblique end surfaces 13 a and 13 b of the opening 13 are inclined rather than the side surface of the lid 2. Such a form may be formed by chance due to the relationship with the side groove main body 1 that has already been installed when the inclination angle is consciously adjusted, or when only the lid 2 is replaced. obtain. Even if it is such a form, as shown in FIG.4 (c), when a load acts on the cover part 2, if the cover part 2 does not rotate using the lower end of the opening part 13 as a fulcrum, the cover part 2 cannot move, and the rotation of the lid portion 2 is prevented by the difference in thickness of the lid portion 2, so that the state of the lid portion 2 cannot be changed. In the above, when the load acts only on one side, as shown in FIG. 4D, the opening end face 13a and the lid 2 on the side on which the load acts (for example, the left side in the figure). By making the side surface 21a vertical, the rotation of the lid 2 as described above can be more sufficiently prevented.

  In any form, the lid portion 2 includes an upper portion having a width W3 wider than the opening width W1 of the opening portion 13 (see FIG. 2), which protrudes upward from the upper end of the side groove main body 1. It doesn't let you. That is, a flat surface is formed on both sides of the water collecting groove 12 at the upper end of the side groove main body 1, and the upper end surface of the lid portion 2 engaged with the opening 13 is substantially equal to the upper end flat portion of the side groove main body 1. It stops at a certain height. Then, the upper end surface of the lid portion 2 receives contact with the tire surface and the like when the vehicle or the like passes along with the upper end flat portion of the side groove main body 1. Therefore, it is possible to prevent the upper end surface of the lid portion 2 from greatly protruding from the side groove main body 1 to concentrate the weight of the vehicle or the like.

  Next, usage modes of the present embodiment will be described. As shown in FIG. 5, a plurality of same-type side groove bodies 1 a, 1 b, 1 c... Configured with a predetermined unit length are made continuous and embedded in the side of the road. In this way, by continuing the side groove main bodies 1a, 1b, 1c,..., The water collecting grooves 12a, 12b, 12c,... Are also continuous, and the drainage channel 11 and the opening 13 are also continuous. Then, the lid 2 is not made continuous, but is engaged with the opening 13 with a predetermined gap. At this time, for example, a plurality of lid portions 2 of the same type are configured to be slightly shorter than the unit length of the side groove main body 1, and the lid portions 2 are engaged with the side groove main bodies 1a, 1b, 1c,. Thus, a gap can be formed in the middle of the adjacent lid portions 2 with the length of the side groove main body 1 as a unit. According to such use, both ends of the lid 2 that closes the opening 13 of the gutter main body 1 are opened, and rainwater can flow into the drainage channel 11.

  In addition, a lid portion 2 having an individual unit length is provided regardless of the side groove main body 1, and the lid portion 2 is appropriately continued to close the opening 13 of the side groove main body 1 to thereby drain the water channel 11. Inflow can be restricted. Then, by installing the lid 2 with a gap only at a position suitable for inflow into the drainage channel 11, it is possible to allow rainwater to flow into the drainage channel 11 from that position.

  Next, a second embodiment of the present invention will be described. In the present embodiment, the lid portion 2 in the first embodiment is modified, and as shown in FIG. 6A, at least one of the side surfaces 121a and 121b of the lid portion 102 is shown (both in the figure). (Ii) Notches 123a and 123b are formed. With this configuration, as shown in FIG. 6B, when the lid 102 is engaged with the opening 113 of the side groove body 101, the wedge-shaped portion of the lid 102 abuts on the opening 113 ( On the other hand, the abutting area is referred to as an abutting area), while the notches 123a and 123b formed on the side surfaces 121a and 121b of the lid 102 are not in contact (the non-abutting area is referred to as a non-abutting area). ).

  When the opening portion 113 of the gutter body 101 is closed by the lid portion 102, the contact region is locked while being in contact with the end surface of the opening portion 113, as in the first embodiment. Is stably fixed. On the other hand, in the non-contact region, narrow grooves 124a and 124b to the extent that rainwater can be injected between the oblique end surfaces 113a and 113b of the opening 113 are formed. 124b reaches the drainage channel 111, and the rainwater once flowing into the water collecting groove 112 can be allowed to flow into the drainage channel 111. Therefore, when the plurality of lid portions 102 are engaged with the opening 113 along the longitudinal direction of the side groove main body 101, there is no need to provide a gap for flowing rainwater or the like into the drainage channel 111. It can be constructed by engaging the lid 102 over the entire area.

  The embodiments of the present invention are as described above, but various aspects can be taken without departing from the spirit of the present invention. For example, in the second embodiment, the contact region and the non-contact region that constitute the lid 102 may be provided in the opening 113 of the side groove main body 101. In this case, as shown in FIG. 7A, the entire lid portion 102 is configured to have a wedge shape in cross section, and intermittent notches 115a, 115b... In the opening 113 of the side groove body 101. Is provided. If comprised in this way, as shown in FIG.7 (b), when closing the opening part 113 by the cover part 102, the side surface of the cover part 102 will be carried out by the part in which the notch parts 115a, 115b ... are provided. Can be configured as a non-contact region (this is a non-contact region), while the portions not provided with the notches 115a, 115b,... An area that abuts against the side surface of 102 (this is an abutment area) can be configured. As described above, by providing the contact area and the non-contact area in the opening 113 of the side groove main body 101, rainwater or the like flowing into the water collecting groove can be allowed to flow down to the drainage channel 111.

  In addition, although the water collecting grooves 12 and 112 of each of the above embodiments are only illustrated with a rectangular cross-sectional shape, the shape is not limited to a rectangular shape, and may be appropriately set to a shape that can exhibit the water collecting effect. It can be changed. For example, in the first embodiment, if the lid portion 2 is provided so that the upper surface of the lid portion 2 is lower than the upper surface of the side groove body 1 without configuring the water collecting groove 12 having an obvious groove shape, It is also possible for the upper surface of the lid portion 2 to function as a water collecting groove. Further, in changing the shape, a curved water collecting groove 212 may be configured as shown in FIG.

  Further, as shown in FIG. 8, both end surfaces 213a and 213b of the opening 213 provided in the side groove main body 201 are configured to have a plurality of steps (FIG. 8 has three steps), and the side surfaces 221a and 221b of the lid 202 are also formed. Similarly, a configuration having a plurality of steps (three steps in FIG. 8) is also possible. In this case, the lid 202 is fixed as a wedge at any step between the opening end faces 213a and 213b of the gutter body 201. That is, as shown in FIG. 9, when the vicinity of the lower end of the lid portion 202 is locked at the lower stage of the side groove main body 201 (FIG. 9A), the vicinity of the center of the lid portion 202 is locked at the middle stage of the side groove main body 201. When it is done (FIG. 9B), the lower end of the lid 202 may be formed in the upper stage of the side groove main body 201. By adopting such a configuration, even if the function as a wedge is not exhibited due to the side surfaces 221a and 221b of the lid portion 202 being scraped off, it can be replaced by other portions. is there.

    Moreover, although the specific numerical value is not shown about the width | variety of the opening parts 13 and 113, the drainage channels 11 and 111 can be cleaned by setting it as the structure which has sufficient width. The lids 2 and 102 are engaged with the openings 13 and 113, so that even if the openings 13 and 113 are wide, it is possible to prevent the wheel from being removed or the pedestrian falling.

  Furthermore, although the opening parts 13 and 113 showed only the form opened along the centerline of the water collection grooves 12 and 112 so that the water collection grooves 12 and 112 may be arrange | positioned at the both sides, this opening part 13 is shown. , 113 may be configured to open on one side of the water collecting grooves 12, 112, that is, the water collecting grooves 12, 112 may be disposed beside the openings 13, 113. In such a configuration, when embedding the gutter body 1, 101, the side where the water collecting grooves 12, 112 are provided is installed close to a road or the like. Thereby, the rain water etc. which should be drained from the surface, such as a road, can be made to flow in into the water collecting grooves 12 and 112 before the opening parts 13 and 113. In the above configuration, when the contact region and the non-contact region as shown in the second embodiment are provided, the non-contact region is configured only on the side where the water collecting grooves 12 and 112 are configured. Then, the object according to the second embodiment can be achieved.
