  Next, the construction procedure of the gutter block structure according to the present invention will be described with reference to FIGS. FIG. 6 is a front view showing the curb block and the block joint penetration aid before asphalt construction. FIG. 7 is a plan view and a front view showing the curb block and the block joint penetration entrance aid after asphalt construction. FIG. 8 is a side view showing a comparative embodiment of the side groove block structure. In the drawing, there is a gap between the curb block and the auxiliary tool for easy understanding, but the actual construction is in contact.

  First, as shown in FIG. 1 and FIG. 2, a side groove excavation portion (excavation hole) 18 in which the side groove block 2 is embedded is excavated at the boundary portion between the roadway 50 and the sidewalk 60, and a concrete foundation 19 is applied to the bottom portion thereof. Set up. The foundation 19 is placed such that the upper surface of the foundation gradually inclines downward toward the water collecting basin (not shown). Are connected and fixed. In addition, packing is attached to the packing groove 12 on the end face of the side groove block 2, and the side groove blocks 2 are arranged in a row through the packing. In this way, by gradually changing the embedding depth of the side groove block 2 and arranging the side groove blocks 2 in tandem, it is possible to ensure the inclination of a series of water channels (flow paths 5).

  Next, the increased concrete 10 is laid horizontally so as not to block the opening 6 in the recess 11 on the upper surface of the side groove block 2, and the curb block 3 is installed on the increased concrete 10. Even if the embedding depth of the side groove block 2 is gradually changed to ensure the inclination of a series of water channels (channel 5), the curb block 3 is installed after the increased concrete 10 is laid on the upper surface of the side groove block 2. A series of curb blocks 3 can be laid horizontally if the level of the upper surface of the increased concrete 10 is ensured, that is, if the thickness of the increased concrete 10 is gradually adjusted.

  On the gutter block 2, the curb blocks 3 are arranged in tandem along the longitudinal direction with the opening 6 closed, and the curb blocks 3 serve as a boundary between the roadway side and the sidewalk side. As shown in FIG. 6, between the adjacent curb blocks 3 and 3, a block joint squeeze mouth auxiliary tool 4 is interposed. The squeeze mouth auxiliary tool 4 has an inverted T-shaped front shape, the pair of upright plate portions 41 and 42 are positioned between the curb blocks 3 and 3, and the leg portions 43 and 44 are the curb block 3. 3 is located between the curb blocks 3 and 3 and does not come off or rattle. When the squeeze mouth assisting tool 4 shown in FIG. 4 is used, only the opening located between the curved portions (chamfered portions) 45 of the standing plate portions 41 and 42 on both sides becomes the rainwater squeeze mouth 30. Accordingly, rainwater on the roadway side is directly swallowed from the rainwater penetration port 30 located on the roadway side and guided into the flow path 5 of the side groove block 2, and the rainwater on the sidewalk is once swallowed on the curb block and then swallowed. Become.

  On the other hand, when the squeeze mouth assisting tool 4 shown in FIG. 5 is used, the sewage squeeze mouth 30 located between the curved portions 45 of the upright plate portions 41 and 42 on both sides and the part of the ceiling surface portion 48 are sunk. A mouth 31 is formed. If a part of the ceiling surface portion 48 is thus opened to form the upper penetration port 31, the rainwater on the sidewalk side can be guided directly from the upper penetration port 31 into the flow path 5 of the side groove block 2.

  The curb block 3 of the present embodiment is a barrier-free type with a small height difference between the pavement surface 51 on the roadway side and the pavement surface 61 on the sidewalk side, and the vertical dimension of the curb block 3 is small. When a normal curb block having a large vertical dimension is used, as shown in FIG. 8, the lower end portion of the curb block 33 on the roadway side can be cut out to form a rainwater penetration port 34. However, since the barrier-free type curb block 3 has a small vertical dimension, it is not possible to open the mouth 34 with the same structure as the normal curb block 33. Therefore, when the barrier-free type curb block 3 is used, a structure in which the auxiliary mouthpiece 4 is inserted in the joint between the curb blocks 3 and 3 as in the side groove block structure 1 according to the present invention is adopted. It is beneficial.

  Next, as shown in FIG. 7, asphalt pavements 52 and 62 on the roadway side and the sidewalk side are constructed. As described above, the squeeze mouth auxiliary tool 4 has a sidewalk side connecting surface portion 46 and a roadway side connecting surface portion 47, and when asphalt pavement, the asphalt mixture enters the flow path 5 from the gap between the curb blocks 3, 3. Prevents intrusion. Since the asphalt pavements 52 and 62 on the roadway side and the sidewalk side are constructed after the execution of the gutter block structure 1 in this way, a gap is simply left between the curb blocks 3 and 3 (joints) so as to swallow from here. However, there is a problem that the asphalt mixture enters the flow path 5 through the gap during the asphalt pavement 52 or 2. Furthermore, if a grating or a net is attached to the gap between the curb blocks 3 and 3 from above, it is easy to come off, so a fastening tool for preventing the comet is required.

  As described above, according to the side groove block structure 1 according to the present invention, the side groove block 2 is embedded in the boundary between the roadway 50 and the sidewalk 60 and the curb block 3 is placed on the side groove block 2. It is sufficient to excavate only the width necessary to bury 2. Therefore, compared with the prior art, the excavation width is narrow, and it is easy to reduce the number of work steps accordingly.

  Further, a block joint squeeze mouth assist tool 4 is interposed between the adjacent curb blocks 3, 3, and at least the curved portion 45 on the roadway side of each upright plate portion 41, 42 of the squeeze mouth assist tool 4. Since the rainwater penetration port 30 is opened and communicated with the opening 6 of the flow path 5, even a curb block 3 of a barrier-free type with a small vertical dimension is connected between the curb blocks 3, 3 ( ) Can be opened with a rainwater trap 30.
