Description

  The present invention relates to a method for constructing a road drainage system that allows rainwater or groundwater for snow removal sprayed on a road to penetrate into the ground.

  A general paved road has a drainage section on the side of the road. For example, rainwater that falls on the road flows from this drainage section into a rainwater basin and drains into a nearby river through underground piping. It has come to be.

  For this reason, a large amount of rainwater flows from the road into the river during heavy rain, which may increase the river and cause flooding.

  Many snowfall areas are equipped with road snow removal equipment that pumps groundwater and sprinkles the roads. However, the above-mentioned road drainage equipment does not return the groundwater for snow removal to rivers, etc. In many areas, subsidence due to groundwater pumping is a problem.

  Therefore, conventionally, a drainage facility has been attempted in which a side wall portion and a bottom wall portion of a gutter block are made of a water-permeable material so that rainwater and the like permeate into the ground from the water-permeable material.

  However, the side groove block in which the side wall portion and the bottom wall portion are made of a water-permeable material has a low durability because the strength of the water-permeable material portion is low.

  In addition, if this water-permeable material becomes clogged due to aging, there is no appropriate means for restoring the water permeability, and the water-permeable function may be lost in some cases.

  In view of such a current situation, the present invention is intended to solve this problem, and while the side groove block has a drainage function, the side groove block can be constructed without causing a significant decrease in strength, and clogging occurs.

  Since the present invention is configured as described above, water that has flowed into the bottom of the side groove block arranged side by side on the road side during rain or when the snow-melting equipment is in operation (when watering the groundwater) has a plurality of side grooves through the water-permeable material. As it surely flows into each mounting recess at the bottom of the block, it is drained from each mounting recess to the gravel layer at the bottom of the foundation through drainage pipes and penetrates well into the ground. It becomes possible to construct drainage equipment for roads, and the mounting recesses formed at the bottom of each side groove block are formed without penetrating the bottom, so the strength of this side groove block may be greatly impaired. Or, although it penetrates part of the bottom part of the side groove block vertically, it is not configured to form a penetration part over a wide area of the bottom part, so that the strength drop of the bottom part is kept small and has almost the same durability as existing products. Side groove block In addition, drilling holes that reach at least the gravel layer below the foundation part are formed by drilling the foundation part. Since it is inserted and fixed in the buried state, water flowing from the ground through this drain pipe can be surely drained to at least the gravel layer, and the drain pipe inserted in the dug hole prevents the foundation from collapsing In order to do so, it becomes a construction method that does not damage the foundation, and in addition, a water-permeable material is fitted in each mounting recess and the upper opening of each drain pipe is closed with this water-permeable material The drainage pipe is hidden by the water-permeable material and looks good, and a thin water-permeable material can be fitted in the mounting recess that does not penetrate the bottom of the side groove block.

  Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  A plurality of side groove blocks 3 such as L-shaped side grooves 3A and U-shaped side grooves are fixed side by side on a base portion 2 formed in the ground beside the road 1, and each side groove block 3 is fixed on the base portion 2. Before or after fixing, an upper surface portion of the bottom portion 4 is recessed in the bottom portion 4 of each side groove block 3 to form an attachment recess 5 that does not penetrate the bottom portion 4 vertically. The place 5 is formed to the full width of the side groove block 3 in the juxtaposed direction.

  Then, the mounting recess 5 is continuous with the bottoms 4 of the plurality of side groove blocks 3 fixed in parallel along the direction in which the side groove blocks 3 are arranged side by side.

  At this time, since the mounting recess 5 formed on the upper surface of the bottom of the side groove block 3 is formed without penetrating the bottom 4, the strength of the side groove block 3 (the bottom 4 thereof) may be greatly impaired. Absent.

  Subsequently, a part of each of the mounting recesses 5 is drilled downward to form a digging hole 6 that penetrates the bottom part 4 of the side groove block 3 and reaches at least the gravel layer 2A of the foundation part 2 below. When a drain pipe 7 having a length equivalent to the digging length of the digging hole 6 is inserted into each digging hole 6 and fixed in an embedded state, a drainage channel that leads from the mounting recess 5 to at least the gravel layer 2A. Will be formed.

  At this time, although a part of the bottom part 4 is vertically penetrated, the digging hole 6 does not penetrate the wide area of the bottom part 4, so that the strength of the bottom part 4 is not greatly impaired.

  Accordingly, the strength originally possessed by the side groove block 3 (the bottom portion 4) is maintained as much as possible while being configured to form a recess or a through hole in the bottom portion 4, and is as high as the existing product. The side groove block 3 exhibiting durability can be constructed.

  Moreover, since the drain pipe 7 inserted in the digging hole 6 prevents the foundation part 2 from collapsing, the foundation part 2 will not collapse, although the foundation part 2 is dug down.

  Subsequently, when the water permeable material 8 is fitted in the fitting recesses 5 and the upper openings of the drain pipes 7 are closed with the water permeable material 8, the drain pipes 7 are connected to the water permeable material 8. Hidden and good appearance.

  Moreover, since the mounting recess 5 that does not penetrate the bottom portion 4 of the side groove block 3 is formed with a shallow bottom, a thin water-permeable material 8 can be fitted therein. Therefore, for example, it is possible to adopt a thin water-permeable material 8 whose water-permeable function can be easily recovered simply by washing. For such a road, the water-permeable material 8 has excellent maintainability. It becomes possible to construct drainage equipment.

  In the drainage system for roads constructed in this way, water flows into the bottom part 4 of the gutter block 3 on the side of the road 1 when it rains or when the snow extinguishing equipment is in operation (when the groundwater is sprinkled). The dead water surely flows through the water-permeable material 8 of the bottom 4 into the mounting recess 5 formed to the full width of the side groove block 3 in the side-by-side direction. And it flows down from the recessed part 5 for attachment through the drainage pipe 7, is drained to the gravel layer 2A of the foundation part 2 lower layer, and osmose | permeates into the ground.

  Therefore, rainwater that has fallen on the road 1 can be infiltrated into the ground without draining into rivers and sewers, so it is possible to reduce the increase in rivers and water in sewers during heavy rains, contributing to flood prevention. It will be.

  In addition, since groundwater for snow removal during winter can be permeated and reduced into the ground, land subsidence can be mitigated.

  In urban areas, heat islands are reduced due to heat on the paved road 1 in the summer, but the effect of suppressing the rise in temperature can be expected by infiltrating water into the ground.

  In addition, the road drainage system of the present invention can be applied to the bottom 4 of the gutter block 3 that has already been installed on the side of the road 1 in the same manner as described above.

  In addition, a mounting recess 5 that does not penetrate through the bottom 4 in the vertical direction is integrally formed in advance on the upper surface of the bottom 4 to the full width in the side-by-side direction of the side groove block 3, and a part of the mounting recess 5 is formed in advance. A gutter block 3 integrally formed with a through hole 9 vertically passing through the bottom part 4 is brought into the field and fixed on the base part 2, and then the base part 2 positioned below each of the pipe through holes 9 is fixed. A part of the hole 6 is drilled downward to form a digging hole 6 that reaches at least the gravel layer 2A in the lower part of the base part 2, and the digging holes 6 and the pipe through holes 9 are provided in communication with each other. After each drain hole 7 having a length equivalent to the hole length of the communication hole portion is inserted into each communication hole portion composed of each dug hole 6 and each tube passage hole 9 and fixed in an embedded state, The water-permeable material 8 is attached to the fitting recess 5 in a fitted state, and the water-permeable material 8 Serial may be to close the upper opening of each tube through the hole 9.

  For example, if the depth of the mounting recess 5 is set to 30 mm or less, the shallow mounting recess 5 can be easily formed and has excellent maintainability. The thin water-permeable material 8 can be used for fitting, and the strength reduction of the bottom portion 4 of the side groove block 3 due to the formation of the mounting recess 5 can be made very small, so that the side groove block 3 has the desired strength. The close strength can be reliably maintained.

  Further, for example, if the water-permeable material 8 is formed of a porous plate having a thickness of 30 mm or less, the water-permeable material 8 may cause clogging due to aging, but a thin porous material having a thickness of 30 mm or less. If it is a plywood, it can be removed by rinsing it with water pressure of water, so it is excellent in maintainability.

  Further, for example, the water-permeable material 8 has deformation resistance, and the surface of the water-permeable material 8 is substantially flush with the upper surface portion of the bottom portion 4 of the side groove block 3 when fitted in the mounting recess 5. If it is composed of a plate material that is in a single state, a person can walk on the water-permeable material 8 and a vehicle wheel or the like can travel as well as a normal gutter block 3, and a drain pipe 7 can also be attached. Since the recess 5 is also hidden by the water-permeable material 8 and has the same appearance as the existing gutter block 3, the appearance is good.

  Further, for example, a part of the mounting recess 5 is perforated downward so as to penetrate the bottom portion 4 of the side groove block 3 and the base portion 2 below the side groove block 3, and the ground below the base portion 2. If the digging hole 6 reaching to the inside is formed, and the drainage pipe 7 having a length equivalent to the digging length of the digging hole 6 is inserted into the digging hole 6 and fixed in an embedded state, Rainwater flowing into the side of the road 1 will surely penetrate into the ground.

  Further, for example, if the drainage pipe 7 is formed with a plurality of drainage small holes 10 scattered on the circumferential surface of the pipe, the drainage pipe 7 is connected not only from the lower end opening of the drainage pipe 7 but also through the plurality of drainage small holes 10. Since the water drains from the surface and penetrates into a wide area, it becomes difficult to form a brittle part in the ground compared to the case where the drainage points are concentrated in one place, and even if the geology directly under the drainage pipe 7 is clay Even if it is a stratum that is difficult for water to penetrate, such as quality, water is drained around the drainage pipe 7 through the drainage small hole 10, so that it is difficult to cause poor drainage such as backflow. Become.

  A first embodiment of the present invention will be described with reference to FIGS.

  A present Example concerns the construction method of the drainage equipment for roads provided in 3 A of L-shaped side grooves as the side groove block 3 fixed to the road 1 side by the side-by-side state as shown in FIG. Moreover, in drawing, the construction method with respect to the L-shaped side groove 3A already constructed is shown.

  Specifically, first, the bottom 4 of the L-shaped side groove 3A fixed in a side-by-side manner on the side of the road 1 is recessed in the upper surface of the bottom 4 so that the bottom 4 does not penetrate vertically. A recess 5 is formed.

  More specifically, as shown in FIG. 2, the concrete cutter 12 cuts several portions 13 on the upper surface of the bottom 4 of the L-shaped side grooves 3A in the vicinity of the rising portion 11 along the parallel direction of the L-shaped side grooves 3A. 2 is inserted into the container by smashing and removing the portion sandwiched between the right and left cuts 13 in FIG. 2 to form a rectangular container in a plan view. The working recess 5 is formed over the entire width in the juxtaposed direction of the L-shaped side groove 3A (the entire width).

  Therefore, in this embodiment, the mounting recess 5 is provided along the direction in which the L-shaped side grooves 3A are arranged at the bottom 4 of the plurality of L-shaped side grooves 3A arranged in parallel. In this embodiment, as shown in FIG. 1, drainage basins 17 are installed between L-shaped side grooves 3A at appropriate intervals, and rainwater flowing into the basin 17 is transferred to rivers as usual. It is configured to be drained.

  Further, the mounting recess 5 has a width dimension in a direction orthogonal to the juxtaposed direction of the L-shaped side grooves 3A set to about 70 to 120 mm and a recessed depth dimension set to about 15 to 20 mm. When the formation dimension of the mounting recess 5 is set in this way, the strength drop of the L-shaped side groove 3A due to the formation of the mounting recess 5 is small, and is substantially equal to the strength that the L-shaped side groove 3A originally has. It has been confirmed that it exhibits the strength of.

  Next, a portion of each of the mounting recesses 5 is drilled downward to penetrate the bottom portion 4 of the side groove block 3 and at least the gravel of the lower layer of the base portion 2 formed in the ground below the side groove block 3. A digging hole 6 reaching the layer 2A is formed. In the figure, reference numeral 2B denotes a concrete layer that is an upper layer of the foundation part 2.

  More specifically, as shown in FIG. 3, a hole having a length in the vertical direction of about 30 mm in diameter is formed at an appropriate position of the mounting recess 5 by using a drill 15 equipped with a drilling bit 14 for drilling. Even if the hole penetrates the bottom part 4, the hole is continuously drilled to the base part 2, and the hole formed from the bottom part to the base part 2 is defined as the digging hole 6. That is, the digging hole 6 is configured by a through-hole formed in the bottom portion 4 and a digging hole formed in the base portion 2. In the present embodiment, the dug hole 6 is dug until reaching the ground below the base portion 2 (see FIG. 3).

  Moreover, as shown in FIG. 1, the case where the dug-down hole 6 is formed in two places for each mounting recess 5 (one L-shaped side groove 3A) is shown.

  Next, a drain pipe 7 having a length equivalent to the digging length of the digging hole 6 is inserted into each digging hole 6 and fixed in an embedded state.

  As shown in FIGS. 4 and 5, the drain pipe 7 has a pipe diameter substantially matching the inner diameter of the digging hole 6, that is, a pipe diameter of about 30 mm, and has a vertically elongated slit-like drain hole in the pipe peripheral surface. Adopts a tube with multiple 10s.

  In addition, a short pipe-shaped filter 16 having a mesh attached to the upper part thereof is detachably fitted to the upper opening of the drain pipe 7 so as to prevent dust from entering the drain pipe 7. . The filter 16 can be removed and cleaned when clogged, and can be replaced when broken.

  Next, a water-permeable material 8 is attached to each of the mounting recesses 5 in a fitted state, and the upper openings of the drain pipes 7 are closed with the water-permeable material 8.

  The water-permeable material 8 is formed into a hard porous body by solidifying gravel, rubber chips, plastic pieces, wood pieces, etc. with an adhesive, has water permeability, and deformation resistance that does not easily deform when a load is applied. Thus, a person can walk on the water-permeable material 8 and wheels can run. In addition, the description “the water-permeable material has deformation resistance” in claim 6 is not a description intended only for deformation resistance that does not cause deformation at all when a load is applied. It is used in the meaning including those having deformation resistance that causes deformation.

  Further, as shown in FIGS. 6 and 7, the water-permeable material 8 is just fitted into the mounting recess 5, and at this time, the surface of the water-permeable material 8 is the bottom 4 of the L-shaped side groove 3A. It is formed in a thin plate having a substantially rectangular shape in plan view that is substantially flush with the upper surface portion. That is, this water-permeable material 8 has a width dimension in a direction orthogonal to the juxtaposed direction set to about 70 to 120 mm and a plate thickness dimension set to about 15 to 20 mm.

  According to the applicant's prototype experiment, if the water-permeable material 8 has a thickness of about 15 to 20 mm, even if clogging occurs, the clogging can be easily eliminated by washing with water pressure of about the water level. It has been confirmed that

  Further, the water-permeable material 8 is configured to be press-fitted into the mounting recess 5 so that it can be removed from the mounting recess 5 during maintenance. In addition, since the water-permeable member 8 can be removed, for example, when a component is damaged, it can be easily repaired and replaced at the site, so that the maintenance performance is excellent.

  Next, the operation of the road drainage system of this embodiment constructed in this way will be described with reference to FIG.

  When it is raining or when snow-melting equipment is in operation (when groundwater is sprinkled), water flows into the bottom 4 of the L-shaped side groove 3A on the side of the road 1, and the water that has flowed into the bottom 4 passes through the water-permeable material 8 at the bottom 4. It will surely flow into the respective mounting recesses 5 that are continuously present in the direction in which the L-shaped side grooves 3A are arranged side by side.

  Then, the water flows down from the mounting recess 5 through the drain pipe 7, drains into the ground below the base portion 2, and penetrates into the ground.

  At this time, as shown by the arrows in FIG. 7, the water is drained not only from the lower end opening of the drain pipe 7 but also from the peripheral surface of the pipe through the plurality of drain holes 10 so that the water penetrates in a wide range. It will be. Therefore, it becomes difficult to form a brittle portion in the ground as compared with the case where the drainage points are concentrated in one place.

  Even if the geology directly under the drainage pipe 7 is a layer such as clay that is difficult for water to permeate, water is drained to the periphery of the drainage pipe 7 through the small drainage holes 10 so Insufficient drainage.

  In the figure, reference numeral 18 is a sidewalk, and 19 is a reinforcing bar provided in the L-shaped side groove 3A.

  In the present embodiment, the case where road drainage equipment is constructed for the L-shaped side groove 3A that has already been constructed is shown, but this drainage equipment may be constructed when the L-shaped side groove 3A is newly installed. Moreover, in the case of construction at the time of new installation, the said mounting recess 5 may be formed before fixing each L-shaped side groove | channel 3A on the base part 2, and may be formed after fixing.

  A second embodiment of the present invention will be described with reference to FIG.

  In this embodiment, when the L-shaped side groove 3A is newly installed, the bottom recess 4 has the L-side groove 3A in which the mounting recess 5 and the through-hole 9 for inserting the drainage pipe 7 are integrally formed in advance during concrete molding. Is used.

  Further, the L-shaped side groove 3A of the present embodiment shows a type having a length as compared with that of the first embodiment.

  In the case of the present embodiment, although not shown in detail, a plurality of L-shaped side grooves 3A are fixed in a juxtaposed state on the base portion 2, and the L-shaped side grooves are formed on the bottoms 4 of the plurality of L-shaped side grooves 3A fixed in parallel. After the mounting recesses 5 are provided so as to be continuous along the juxtaposed direction of 3A, a part of the base portion 2 located at the lower part of each of the through holes 9 is drilled downward, for example, at least The digging holes 6 reaching the gravel layer 2 </ b> A of the lower part of the foundation portion 2 are formed, and the digging holes 6 and the pipe through holes 9 are provided in communication with each other, and the digging holes 6 and the pipe through holes 9 that communicate with each other. The drainage pipe 7 having a length equal to the length of the communication hole is inserted into each communication hole and fixed in an embedded state, and then the water-permeable material 8 is inserted into each mounting recess 5. It attaches to a fitting state and obstruct | occludes the upper opening part of each said tube through-hole 9 with this water-permeable material 8. FIG.
