JP5791403B2 - Construction method of free-gradient gutter - Google Patents

Description

The present invention relates to a method for constructing a gutter that is laid and constructed, for example, on the side of a road or across a road.

  Conventionally, as described in JP-A-10-140641, many patent applications and many patents have been obtained for variable side grooves forming so-called water channels.

  However, the conventional variable gutter must hit the invert on-site, and a certain amount of time is required for the work, and also the curing time until the invert solidifies, especially across the road in the width direction. When the gutter was laid and constructed, the road had to be closed for a long time.

Furthermore, due to the situation at the side gutter construction site, when the slope of the water channel in the gutter must be reversed to the slope of the side gutter construction site, or when laying the gutter across the road, Unlike the slope of the road formed as a downward slope facing sideways, there was a case where it was desired to make the water channel in the side groove of the downward slope from one end to the other end in the width direction of the road. In order to construct a water channel with cast-in-place concrete, a long working time is required, and it is a technically difficult task.

Japanese Patent Application Laid-Open No. 10-140641

Thus, the present invention was devised to solve the above-mentioned conventional problems, and it is not necessary to hit the invert on-site, so that the work time and the invert curing time are not required, and the road is particularly wide. When laying a gutter across the road, it is not necessary to block the road for a long period of time. From the situation of the gutter construction site, the slope of the water channel in the gutter must be opposite to the slope of the gutter construction site. No, or when laying a gutter across the road, it is completely different from the road slope formed as a downward slope facing the both sides in the width direction from the center. It is intended to provide a method for constructing a free-gradient side gutter that can be constructed easily and at a low cost when it is desired to make the water channel in a side grove inclined downward toward the side. A.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows the configuration of the first embodiment of the present invention. The construction inclination of the side groove 1 itself is 0%, that is, it is laid in the horizontal direction, but the direction of the water channel in the side groove 1 is inclined. Is configured so as to be inclined downward from the left side to the right side in FIG.

  A description will be given of performing the laying construction of the side groove 1 as shown in FIG. 1 by the construction method of the present invention.

  First, at the construction site where the gutter 1 is constructed, the inclination of the construction location where the gutter 1 is to be laid is measured and determined. In other words, first, the upper surface inclination of the side groove 1 to be laid and constructed is measured and determined.

  As shown in FIG. 1, in the first embodiment, the side groove 1 is laid and installed by connecting free gradient side groove units 9... In the horizontal direction. That is, the upper surface inclination of the side groove 1 is 0%.

  Next, the inclination of the water channel formed in the side groove 1 is determined. That is, the inclination required of the water channel in the side groove 1 on site is determined to be a water channel having a downward slope from the left side to the right side in FIG.

  Therefore, the required side groove top surface inclination and the water channel inclination of the side groove water channel are determined in advance by the measurement work performed at the construction site as described above.

  Next, based on the respective inclinations determined at the construction site, the side groove unit 4 and the invert unit formed in the split connection type so as to have the inclination corresponding to the required side groove upper surface inclination and water channel inclination at the time of connection. The free-gradient side groove unit 9 consisting of 5 is manufactured in advance at the factory.

  In addition, regarding the side groove unit 4, the existing side groove unit 4 may be used depending on the case. In this case, only the invert unit 5 may be manufactured at the factory, and may be combined with the existing side groove unit 4 at the construction site and used as the free gradient side groove unit 9.

  Therefore, even when the existing gutter unit 4 is a product of another company, a product that can sufficiently meet the request and can respond can be manufactured.

  Here, as shown in FIG. 1, the code | symbol 6 is a basic crushed stone, and laying | laying of this basic crushed stone 6 becomes a construction in the field.

  Next, a reference numeral 7 is a base block having a substantially rectangular parallelepiped shape, which is manufactured in advance in a factory, and the base block 7 is placed on the basic crushed stone 6 and laid on the construction site.

  An invert unit 5 having the predetermined inclination set in advance at the factory via a mortar 8 on the laid base block 7 and a side groove unit 4 connected to the invert unit 5 Each of the free-gradient side groove units 9 is laid at predetermined locations on the construction site.

  In this case, it is important that when the free-gradient side groove unit 9 is laid in the longitudinal direction, as described above, based on the inclination determined at the construction site, the required side groove upper surface inclination, In this embodiment, since it is a horizontal direction, the inclination is 0% and the channel inclination, and in this embodiment, the downward inclination is inclined from the left side to the right side in FIG. When you do, you have to be connected to have it as a whole.

Any Therefore, factory base block up to 7 depth of laying places, each of the free slope groove unit 9 is laid is the difference or the (dimension), the free slope groove unit 9 which is laid in its place, in particular the invert unit 5 For example, it is necessary to clarify whether the shape is formed by adding a serial number.

  By laying as described above, the inclination of the upper surface of the side groove is 0% as shown in FIG. 1, but the inclination of the water channel inside the side groove 1 is a downward slope from the left side to the right side as viewed in FIG. The slopes of the side grooves as a whole when connected.

  Here, a specific configuration of the free gradient side groove unit 9 will be described with reference to FIGS. 4 to 7.

  First, the side groove unit 4 is provided with a slit 10 penetrating vertically in the center of the upper surface in the width direction, and the upper surface of the side groove is configured to be a downward inclined surface toward the slit 10, and the upper surface of the side groove is formed by the slit 10. The rainwater or the like accumulated in the water can flow into the side groove 1. Further, the side wall 11 of the side groove unit 4 is also configured so as to be able to easily manufacture the side groove units 4 having different heights.

Further, as can be understood from the drawing, the invert unit 5 can be manufactured by freely selecting ones having different inclinations, that is, different gradients.

  FIG. 2 shows a second embodiment of the present invention, in which the construction site of the side groove 1 laid and constructed according to the present invention is a road surface 3 formed as a downward inclined surface from the center toward both sides in the width direction. It is a construction site where the gutter 1 must be laid across the road 2 in the width direction.

  As can be understood from FIG. 2, the direction of the water channel in the side groove 1 laid is from the right side to the left side in FIG. 2, and has a downward slope, and rainwater or the like descends in the water channel. It is configured to flow with a gradient.

  Here, the laying construction method according to the present invention will be described with reference to Example 2.

  First, when it is necessary to lay the gutter 1 across the road 2 as described above, the most important point is to perform the laying work quickly and shorten the traffic blocking period. This is because if the traffic blocking period is long, it will cause a great hindrance to economic activities.

  Conventionally, since the inverted portion of the side groove 1 is made of cast-in-place concrete, time such as a curing period of the invert concrete is required, and the traffic blocking period cannot be shortened. It can be said that the present invention has solved such a problem.

  First, the inclination of the construction location where the gutter 1 is to be laid is measured at the construction site. In other words, the upper surface inclination of the side groove 1 to be laid is measured.

  As shown in FIG. 2, the road 2 is configured as a downward inclined surface from the center in the road width direction toward both ends. As can be understood from FIG. 2, specifically, it is configured as a downward inclined surface having a gradient of about 2% from the center in the width direction toward both ends. Therefore, it is necessary to form the upper surface of the side groove 1 laid across the road 2 with the same inclination.

Next, the inclination of the water channel formed in the side groove 1 is determined.
That is , as described above, the inclination to be laid in the side groove 1 is a downward inclined surface having a gradient of about 2% from the center in the width direction toward both ends, whereas the inclination of the water channel in the side groove 1 is This is because, as understood from FIG. 2, it is determined by setting the water channel to have a downward slope from the left side to the right side in FIG. 2.

  Therefore, the required side groove top surface inclination and the water channel inclination of the water channel in the side groove are measured and determined in advance by the measurement work at the construction site.

  Next, based on the slope measured and measured at the construction site, the slope formed in the split connection type so as to have the required construction surface slope, that is, the side groove top slope and the water channel slope at the time of connection. The side groove unit 4 and the invert unit 5 having the inclination are manufactured in advance in a factory.

  In FIG. 2, reference numeral 6 denotes a basic crushed stone, and the laying of the basic crushed stone 6 is an on-site construction as in the first embodiment.

  Next, a reference numeral 7 is a base block having a substantially rectangular parallelepiped shape, which is manufactured in advance in a factory, and the base block 7 is placed on the basic crushed stone 6 and laid on the construction site.

  Then, the invert unit 5 having the predetermined inclination set in advance at the factory via the mortar 8 on the laid base block 7 and the side groove unit 4 to be connected to the invert unit 5 are provided. The free-gradient side groove unit 9 is connected to each predetermined place on the construction site and laid.
