Description

The present invention relates to a method for laying a water channel that uses a new concrete U-shaped groove and a new lid for an existing water channel laid with, for example, a concrete U-shaped groove and a concrete lid, and extends a new water channel, for example. It is.

  Conventionally, so-called drop lid side grooves such as side grooves have been laid and formed using a concrete U-shaped groove and a cover body having a substantially square plate shape made of concrete that covers the entire upper surface opening.

  In this case, when rainwater or the like accumulates on the ground surface, the grating lid 16 is placed on the upper surface of the existing U-shaped groove in the longitudinal direction of the existing water channel, for example, every 5 meters, in order to smoothly flow the rainwater into the lateral groove. The location was used as a water collection hole for smoothly collecting rainwater or the like in the side groove.

  However, there is a concern that providing the grating lid 16 formed of a special member at intervals of, for example, 5 meters in the above-mentioned side groove may considerably increase the cost.

  Further, conventionally, when the U-shaped groove is laid, if the concrete lid that closes the upper surface opening is completely fixed to the U-shaped groove upper surface opening, the inside of the U-shaped groove cannot be cleaned. The concrete lid was simply placed on the upper surface opening of the U-shaped groove and was not completely fixed.

However, if the concrete lid is placed in a free state on the upper surface opening of the U-shaped groove, a rattle occurs each time a heavy object such as a vehicle passes through the lid, and noise is generated each time. At the same time, there was concern that the concrete lid would be damaged.

By the way, in recent years, the time of existing side groove extension laying work or existing side groove replacement work for the side groove, for example, which has been laid by the conventional U-shaped groove and the conventional lid body has come one after another. There is a demand for laying a water channel using a newly-developed U-shaped groove and lid instead of using an existing U-shaped groove lid.

  Here, when collecting rainwater or the like collected on the ground surface in the gutter, the so-called “urban ditch” is constructed with extremely good water collection and good quality with excellent durability. Is a side groove with a slit groove (refer to Japanese Patent Application Laid-Open No. 2003-49476), but when the side groove with a slit is connected to the existing U-shaped groove and extended and laid, the portion appearing on the ground surface is substantially equivalent. Even if the width and the length were substantially the same, there was a construction client who refused to use it because the width of the internal waterway portion was different.

  Therefore, even if the so-called “urban side gutter” is replaced with the side gutter, it is a U-shaped gutter and a cover body with extremely excellent water collection, and the width and height of the water channel portion of the existing U-shaped gutter are substantially equal. As a result, an extension of existing waterway or replacement of existing waterway was requested.

Japanese Patent Laid-Open No. 2003-49476 FIG.

Thus, the waterway laying method according to the present invention was devised to cope with the above-mentioned problems, and is superior to the conventional waterway formation for the extension laying work or replacement work of the waterway laid in the past. Dust is not deposited inside, and a waterway with good water collection efficiency such as rainwater from the ground can be laid using a new U-shaped groove and lid, and the width and height of the waterway part existing inside An object of the present invention is to provide a waterway laying method that can be made substantially equivalent to an existing U-shaped groove.

With the waterway laying method according to the present invention, it is superior to the conventional waterway formation in the extension laying work or replacement work of the waterway laid in the past.For example, in the ditches, dust etc. does not accumulate inside the waterway, and It has an excellent effect that a water channel with good water collection efficiency such as rainwater can be installed at low cost.

Hereinafter, the present invention will be described based on embodiments shown in the drawings.
1 and 2, reference numeral 1 denotes an existing U-shaped groove having a so-called substantially U-shaped cross section. The existing U-shaped groove 1 is configured to have both side walls 5 and 5 rising substantially vertically from both ends in the width direction of the bottom wall 4, and has a U-shaped water channel portion 6 having a substantially U shape inside. is doing.
Reference numeral 2 denotes an existing lid having a substantially rectangular plate shape that closes the upper surface opening 3 of the U-shaped groove 1.
Conventionally, the upper surface opening 3 of the existing U-shaped groove 1 is entirely covered and covered with the existing substantially rectangular plate-like lid body 2, so that rainwater collected on the ground surface can be smoothly removed from the upper surface. In addition, water could not be collected in the water channel inside the gutter.
Therefore, conventionally, a catching cover 16 for collecting water is provided to the upper surface opening 3 of the existing U-shaped groove 1 as shown in FIG. It was intended for smooth water collection such as rainwater that was placed on the ground surface.
However, the use of a large number of the grating lids 16 is expensive in cost, and earth and sand also flows into the gutter along with rainwater from the gap in the grating, and the earth and sand are U-shaped. Accumulation at the bottom of the water channel 6 would stop the flow of sewage.
Further, the conventional existing lid body 2 is merely placed on the upper surface opening 3 of the existing U-shaped groove 1 and is not fixed.
That is, for example, when the sewage is clogged at a predetermined position of the side groove laid in the ground, it is intended that the existing lid body 2 that is not fixed is opened and the inside of the side groove can be inspected.
However, conversely, when a vehicle or the like passes through the upper surface of the existing lid 2, the existing lid 2 often rattles and generates noise or breaks.
In the present invention, the existing side grooves having the above-mentioned problems can be extended and laid using new members such as the new U-shaped groove 7 and the new lid 8, or the conventional problems can be solved. It has been solved.
Reference numeral 7 indicates a new U-shaped groove. The new U-shaped groove 7 has a U-shaped water channel portion 6 having a width and height substantially equal to those of the existing U-shaped groove 1.
However, the difference from the existing U-shaped groove 1 is that the bottom wall 4 of the new U-shaped groove 7 is provided with a groove 9 for high water flow extending in the longitudinal direction at a substantially central position in the width direction.
As understood from the drawing, the groove of the high water flow groove 9 has a substantially semicircular cross section, but is not limited to such a shape. For example, a shape such as an inverted triangle shape or an inverted trapezoidal shape may be used.
By the way, such a high water flow groove 9 is not formed in the existing U-shaped groove 1. Therefore, in the conventional U-shaped water channel portion 6, the location where water such as sewage flows is the flat surface of the entire top surface of the bottom wall 4 and the pair of side walls 5 rising from both ends of the bottom wall 4 in the width direction. 5 between the inner surface.
Here, since the bottom wall 4 of the existing U-shaped groove 1 is formed as a wide flat surface, the water flowing on the bottom wall 4 tends to spread over the entire width direction of the bottom wall 4.
Therefore, there is no problem when the amount of flowing water is large and the water flow is high and strong. Sludge and garbage are heavy and do not flow with water, and eventually stay on the bottom wall 4.
Then, sludge and garbage that have flowed one after another collide with accumulated sludge and garbage, and eventually accumulate, and the sludge and garbage become a major obstacle, and even the water flow is completely blocked. It happened.
Therefore, the new U-shaped groove 7 according to the present invention first copes with such a situation.
That is, instead of the conventional bottom wall 4 which is a flat surface through which water flows, the high water flow groove 9 is formed at a substantially central position in the width direction of the bottom wall 4, so that even when the amount of water is small. Therefore, it was designed so that sludge, dust and the like do not stay on the upper surface of the bottom wall 4 even when the amount of water is small.
Thus, the high water flow groove 9 is formed in a shape that forms various concave grooves that can make the flowing water flow faster, that is, a high water flow.
The basic design method for the high water flow groove 9 is how quickly a weak water flow is converted into a high water flow, that is, when the amount of flowing water is small, A method of increasing the depth of the water and speeding up the water flow can be considered.
Accordingly, the width of water flow is narrowed and the depth is set to be approximately semicircular or substantially U-shaped so that the water flows quickly even with a small amount of water.
That is, when the amount of water is small and the water flow is weak, the water flowing in the high water flow groove 9 having a shape such as the substantially U shape is collected and flows, and as a result, sludge, dust, etc. are accumulated. It will not be deposited or deposited.
As described above, as the shape of the groove 9 for high water flow, a groove having an inverted mountain shape, a groove formed with an acute angle like the apex angle of an inverted triangle, a groove formed in an inverted trapezoidal shape, etc. Can be considered.

Next, the configuration of the new lid 8 will be described.

The structure of the new lid 8 is greatly different from that of the conventional existing lid 2. As is understood from FIG. 3, it has a substantially rectangular plate shape, and a slit 10 penetrating in the vertical direction is provided at a substantially central portion in the width direction.

  As understood from FIG. 3, the slit 10 has a shape in which the slit width on the lower surface 13 side of the lid 10 is wider than the slit width on the upper surface 12 side of the lid 10.

  That is, on the ground surface, the upper surface side slit width is narrowed so as to limit the rainwater to be introduced into the internal U-shaped water channel 6 as much as possible, thereby preventing the entry of leaves, tree branches or other solid waste. On the other hand, since the taken rainwater is smoothly introduced into the internal water channel, the slit structure is expanded thereafter.

  However, if the slit 10 is formed entirely in the longitudinal direction of the new lid 8, the new lid 8 is divided into two. Therefore, since the new lid 8 is connected to the slit 10 and the connecting and introducing groove portions 11 for guiding the rainwater on the ground surface and smoothly introducing it into the slit 10 are provided at a plurality of locations in the longitudinal direction. is there.

  Therefore, in this embodiment, the new lid 8 is provided at three convenient locations, ie, two locations on both ends in the longitudinal direction and one location in the central portion in the longitudinal direction. However, the installation location and the number of installations of the connecting portion / introducing groove portion 14 are not limited at all.

  Further, the connecting / introducing groove portion 14 is not configured to be connected from the upper part to the lower part of the slit 10 in the height direction. That is, it is configured to connect the intermediate position in the height direction to the lower slit 10 of the new lid body 8 without connecting to the substantially intermediate position in the height direction depending from the upper slit 10 of the new lid body 8. Thus, the connecting / introducing groove 14 has a concave groove shape.

  And the bottom wall 14 of the connection part and introduction groove part 14 is comprised as a bottom face of the same inclination angle toward the other end side from the longitudinal direction one end side of the new cover body 8, and the upper slit 10 vicinity position or a connection part and introduction groove part The rain water collected on the upper surface of the bottom wall 4 of 14 can be efficiently introduced into the U-shaped water channel portion 6.

  Further, the upper surface of the new lid body 8 is also configured as an inclined surface that slopes downward from both ends in the width direction toward the slit 10, so that drainage such as rainwater collected on the upper surface of the new lid body 8 is improved. ing.

  Next, as shown in FIG. 3, a plurality of notches 15 are provided on the outer peripheral end surface of the new lid 8, and after fitting the new lid 8 into the upper surface opening 3 of the new U-shaped groove 7, An adhesive such as mortar is poured into the notch 15 to fix the new lid 8 to the new U-shaped groove 7.

  As a result, a heavy object such as a vehicle is placed on the existing lid 2 which has been a conventional concern and does not rattle and no noise is generated or the existing lid 2 is not damaged.

  Next, the case where the existing side groove laid by the existing U-shaped groove 1 and the existing lid 2 is further laid using the new U-shaped groove 7 and the new lid 8 will be described.

  As shown in FIG. 1, conventionally, an existing U-shaped groove 1 and an existing lid 2 are used to lay and form side grooves, for example. However, since the existing lid 2 completely blocks the upper surface opening of the existing U-shaped groove 1, the water drainage on the ground surface becomes worse. Therefore, as described above, conventionally, the grating lid 16 has been fitted into the upper surface opening 3 of the existing U-shaped groove 1 at an interval of about 5 meters to consider draining of the ground surface.

  Therefore, in recent years, the new U-shaped groove 7 and the new lid 8 having the above-described characteristics and excellent quality are used. The new U-shaped groove 7 and the new lid 8 are configured in such a manner that the existing U-shaped groove 1 and the U-shaped water channel portion 6 that have been laid in the same manner have substantially the same width and height.

  Since these U-shaped grooves are buried leaving the upper surface, the width of the U-shaped water channel portion 6 is different if the width of the upper surface is the same as that of the existing U-shaped groove 1 and the existing lid 2. Although there is not much problem, it is taken into consideration for the above-mentioned construction client.

  Here, the new U-shaped groove 7 is provided with a groove 9 for high water flow extending in the longitudinal direction at a substantially central position in the width direction of the bottom wall 4. Therefore, from the place where the new U-shaped groove 7 is laid, even if the amount of sewage flowing through the U-shaped water channel portion 6 is small and the water flow is slow, the water flow is accumulated in the high water flow groove 9 and relatively flows. It flows faster and has the effect of preventing sludge and garbage from accumulating.

  Next, the new lid 8 is fitted into the upper surface opening 3 and fixed. Since the existing existing lid 2 is not fixed, there are various concerns as described above. However, since the new lid 8 is fixed to the new U-shaped groove 7, the problem has been solved.

  Further, a slit 10 is provided at a substantially central position in the width direction, so that water collecting work such as rainwater collected on the ground surface can be smoothly performed.

  In addition, the upper surface of the new lid 8 is more so because it is formed as an inclined surface having a downward gradient from both ends in the width direction toward the slit 10.

  Further, in the longitudinal direction of the slit 10, there are provided a connecting part / introducing groove part 14 for connecting the new lid body 8 divided by the slit 10 at three places and intended to introduce rainwater collection on the ground surface. The structure considering the durability and water collecting property of the new lid 8 is remarkable.

  Therefore, the grating lid 16 must be used every 5 meters in the longitudinal direction of the side grooves that have been conventionally laid and formed. However, when the new lid 8 is used as in the present invention, for example, at intervals of 5 meters. The use of the grating lid 16 is completely unnecessary.

  By the way, FIG. 9 shows an embodiment in which a new water channel is extended and laid by connecting a new U-shaped groove not equipped with a new lid to the existing U-shaped groove 1 not equipped with an existing lid. is there. As shown in the figure, the width and height of the U-shaped water channel portion 6 are formed to have the same dimensions. However, the new U-shaped groove 7 has a bottom wall 4 that is long at a substantially central position in the width direction. Grooves 9 for high water flow extending in the direction are provided.

  Therefore, if it is a connection like a present Example, about the location which formed the water channel newly, even if it is a thing with little water volume and a weak water flow, a water flow will become quick by the said groove 9 for high water flows, and, Sludge and garbage do not stay.

  Moreover, a new lid 8 can be put on and fixed to the upper opening 3 of the existing U-shaped groove 1 and the upper opening 3 of the new U-shaped groove 7 after the connection work. Even where 1 is already laid, it is possible to provide the same scenery as when a new waterway was laid.

  10 and 11 show an example in which a new water channel is extended and laid, and FIG. 10 shows an example in which the water is laid and extended at a substantially right angle on an intersecting road.

  FIG. 11 shows an example in which a new waterway is newly laid across a crossing road.

  Further, for example, in the example shown in FIG. 10 or FIG. 11, a place where the existing U-shaped groove 1 is laid is selected at a place where severe damage is caused, and the place is replaced with a new U-shaped groove 7 and a new lid 8. It can also be laid.

  Note that the bottom wall 14 of the connecting / introducing groove 11 of the new lid 8 may be formed at a height substantially equal to the upper surface of the new lid 8, and in this case, there is almost no groove. , Only the connecting part.

The place where such an embodiment is adopted is preferably a place where a new water channel is formed at a sloped location, and even if the slit 10 does not have an introduction groove such as rainwater, the U-shaped water channel portion 6 of the side groove can be relatively smoothly formed. Can collect water.
