Description

      The present invention relates to a side groove block for draining rainwater or the like buried in connection with a road or the like, and the degradation / sinking of the pavement portion at the boundary between the side groove block main body and the pavement portion connected to the side groove block, Suppresses / reduces the sinking of the pavement at the boundary with a step perpendicular to the gutter block body, and at the same time, sinks smoothly into the pavement central part of the road, etc. The present invention relates to a gutter block that can be controlled.

      Until now, for example, a side groove block for drainage of rainwater or the like buried in connection with a road or the like has been used, for example, a concrete substantially U-shaped side groove block body covered with a concrete groove cover. Yes.

      That is, in the conventional side groove block, the side wall outer surface of the groove lid portion at the upper part of the side groove block main body and the subsequent side wall outer surface of the drainage channel portion are made smooth and substantially vertical. The pavement connected to the gutter block body is constructed and built in contact with the smooth and vertical surface. For this reason, when an automobile load or the like is loaded on the pavement portion at the boundary portion, the pavement portion is a step where the pavement portion at the boundary portion is perpendicular to the gutter block main body with this smooth and vertical slippery surface as a boundary. It is in a state that is liable to cause subsidence.

      In addition, the gutter block body and the pavement are designed, manufactured and constructed based on their technical standards, etc., so that they both work together and integrally resist mutual sliding caused by external forces such as automobile loads. Such structures are generally not designed, manufactured or constructed.

      Further, the pavement such as a roadway or a sidewalk is usually constructed after the gutter block body is installed at a position / height based on a plan such as a road. The pavement compaction work is usually performed using large heavy machinery such as Macadam rollers and tire rollers, but pavement work near the structure such as the boundary between the side groove block body and the pavement is large. Due to construction restrictions that make it difficult to use heavy machinery, compaction work is being carried out with small machines such as tamper and rammer. For this reason, the pavement compactness of the pavement at the boundary between the gutter block main body and the pavement is relatively low compared to the compaction of the pavement central part such as a road. It is customary.

      In addition, the pavement at the boundary between the gutter block body and the pavement is subject to the wheel load of the vehicle traveling on the roadway, etc. after the start of use on the road, etc. Since it receives repeatedly, it is in an environment where deterioration and subsidence of the pavement portion is more likely to proceed than the central portion of the pavement such as a road.

      When deterioration and subsidence of the pavement at the boundary between the gutter block main body and the pavement progresses, and rainwater accumulates in the depression generated in the pavement layer, drainage of rainwater etc. to the drainage facility such as the gutter block is delayed. As a result, the penetration of rainwater and the like into the roadbed will be accelerated, and the deterioration of the roadbed will progress further. If it becomes so, degradation of the whole pavement part will progress further, a pavement-like crack will generate | occur | produce in a pavement layer, or the subsidence with a level | step difference perpendicular | vertical with respect to a gutter block main body will arise.

      Pavement repair work in the case where the pavement deteriorates and a tortoise-shaped crack generated in the pavement layer or a subsidence with a step perpendicular to the gutter block main body occurs, the pavement layer of the deteriorated and subsidized part is The pavement layer is reconstructed after stripping off and replenishing and repairing a part of the roadbed below it. It suppresses and reduces the subsidence of the pavement again, and controls the subsidence shape as a subsidence that smoothly rubs toward the center of the pavement, such as roads. It is not added to the pavement part, but is simply being performed as a work to restore the conventional pavement function.

      As described above, the side wall outer surface of the conventional side groove block main body is smooth and substantially vertical, so the pavement connected to the side groove block main body side wall outer surface and the side groove block main body side wall outer surface are mutually attached by loading such as an automobile load. The situation is slippery. In addition, the side groove block main body and the pavement are not designed, manufactured, and constructed in general in a structure that actively resists mutual sliding at the boundary. Also, in the construction of pavement work at the boundary between the gutter block main body and the pavement part, there are restrictions on the use of large heavy machinery, and the pavement finish density of that part is relative to the pavement center part such as roads Tend to be finished low. In addition, the pavement part of the boundary part has characteristics according to the road structure regulations that repeatedly receive automobile loads after the start of use of roads, etc. It starts earlier than the part, and with the progress of its deterioration and settlement, a tortoise-like crack is generated in the pavement layer, and a settlement with a step difference perpendicular to the gutter block main body also occurs. Also, the pavement repair work for the degraded part of the pavement at the boundary part is simply a work to restore the previous pavement function, so it is expected that the pavement part will deteriorate and sink again, resulting in pavement repair work. This has led to an increase in costs.

      A gutter block 1 according to a first embodiment for carrying out the present invention will be described with reference to the drawings.

      1 to 4 relate to a first embodiment of the present invention, FIG. 1 is a perspective view showing an example of a side groove block 1, and FIG. 2 shows a stepping plate 7 on a receiving surface 8 of a receiving block portion 9. FIG. 3A is a plan view of an example of a stepping plate 7 provided with a through-hole 25, and FIG. FIG. 3 (C) is a plan view of an example of a stepping plate 7 in which one stepping plate 7 corresponds to one side groove block main body 3, and FIG. FIG. 4A is a longitudinal sectional view showing a main part of an example of the side groove block 1 having a configuration in which the stepping plate 7 is mounted on the receiving surface 8 of the receiving block portion 9 with a hinge structure, and FIG. It is a longitudinal cross-sectional view which shows the principal part of an example of the side groove block 1 with the form which places it on the receiving surface 8 of the receiving block part 9 with a fixed structure.

      The side groove block 1 is a side groove block 1 made of, for example, a side groove block with a beam, for draining rainwater or the like that is buried in connection with a road or the like. The side groove block 1 includes a side groove block main body 3, a receiving block portion 9 protruding from the side wall outer surface 4 of the side groove block main body 3, an insertion hole 11 formed in the side wall 6, and a stepping plate on the insertion hole 11. A tread plate 7 into which the insertion convex portion 10 is inserted is provided. The tread plate 7 is installed across the three surfaces of the bottom surface 29 of the insertion hole 11, the receiving surface 8 of the receiving block portion 9, and the installation surface of the pavement portion 12, and is a boundary portion between the side groove block main body 3 and the pavement portion 12. The side groove block main body 3 and the pavement portion 12 share and support each other via the tread plate 7 with respect to the automobile load or the like loaded on the pavement portion 12.

      The side groove block main body 3, the receiving block portion 9, and the insertion hole 11 are made of concrete and are manufactured integrally. The illustrated gutter block main body 3 has a drainage channel 2 and has a rectangular cross-sectional shape, the central top wall 14 in the longitudinal direction is an opening, and the top wall 14 is closed at both ends. It has a cross-sectional shape. The opening 15 of the top wall 14 can be fitted with a plurality of concrete or steel groove lids 16 so as to be detachable like a conventional U-shaped groove block. The places where the top walls 14 at both ends of the side groove block main body 3 are closed have a combined length that is almost one half of the total length, and function as a beam in the upper part of the side groove block main body 3.

      A block mounting portion 18 on which a part of the lower surface of the pedestrian boundary block 17 is mounted and fixed is provided at the end of the top wall 14 on the side where the stepping plate 7 of the side groove block body 3 is not installed. The walking road boundary block 17 is placed and fixed on the placing portion 18.

      The receiving block portion 9 is provided so as to protrude from the side wall outer surface 4 so that the receiving surface 8 is substantially perpendicular to the side wall outer surface 4 of the side groove block main body 3. The projecting portion lower end of the illustrated receiving block portion 9 is rubbed to the side wall outer surface 4 of the side groove block main body 3 with a smooth inclined surface 21, and the cross section has a trapezoidal shape. Note that the cross-sectional shape does not necessarily have a trapezoidal shape. For example, when the lower end of the projecting portion is rectangular, the pavement finish density at the boundary between the gutter block main body 3 and the pavement portion 12 in the pavement construction is road. Compared to the pavement center portion such as the above, the finish is relatively low, and the tendency of the deterioration and subsidence of the pavement portion 12 at the boundary portion to progress is intensified. In order to suppress this, the trapezoidal cross section of the receiving block 9 is desirable.

      If the length of the vertical surface 19 of the receiving block portion is the rectangular receiving block portion 9 that extends to the bottom surface of the bottom wall 20 of the side groove block body 3, the pavement portion side of the receiving block portion 9 is used. The side surface is a smooth and vertical surface from the receiving surface 8 to the bottom wall 20, which leads to an increase in pavement workability.

      The width of the receiving surface 8 of the illustrated receiving block portion 9 corresponds to the horizontal displacement of the stepping plate 7 according to the vertical step sinking of the pavement portion 12 with respect to the side groove block body 3 and is formed to have a width of about 10 cm. However, the width is the magnitude of the load loaded on the receiving surface 8 and the characteristics of the side groove block 1 (type of side groove block 1: U-shaped side groove block, portal-type gradient variable type side groove block, culvert type Side groove block, side groove block with beam, slit type side groove block, etc.), characteristics of the foot plate 7 (size, shape, material, type of structure), structure in which the foot plate 7 is placed on the receiving surface 8 (movable structure) Hinge structure, fixed structure), pavement construction workability, gutter block 1 manufacturability, and maintenance management of stepping plates and the like.

      Roundness 22 is attached to the pavement side end of the receiving surface 8 of the receiving block 9. In the illustrated example, the receiving block portion 9 is continuously provided along the longitudinal direction of the side groove block main body 3. However, in order to reduce the weight of the side groove block main body 3, the longitudinal length of the side groove block main body 3 is provided. You may provide intermittently along a direction.

      The position of the receiving surface 8 of the receiving block portion 9 from the top surface 5 of the side groove block main body 3 is provided at the boundary between the pavement layer 23 and the roadbed 24, but becomes the pavement layer 23 or the roadbed 24. It is good also as a position. In addition to the above, the characteristics of the side groove block 1, the characteristics of the stepping plate 7, the structure in which the stepping plate 7 is placed on the receiving surface 8, the workability of paving work, the manufacturability of the side groove block 1, the stepping plate 7, etc. It will be optimal in relation to maintenance and management.

      The insertion hole 11 into which the stepping plate insertion convex portion 10 is inserted crosses the stepping plate insertion convex portion 10 along the receiving surface 8 of the receiving block portion 9 from the side wall outer surface 4 to the side wall 6 substantially vertically at both right and left. Drill slightly larger than the surface. In some cases, the vertical direction may be formed in the side wall 6 from the side wall outer surface 4 toward the bottom wall 20 of the side groove block main body 3. The shape of the entrance portion of the insertion hole 11 is the same cross-sectional shape as the stepping plate insertion convex portion 10 to be inserted, and the insertion hole 11 is drilled so as not to hinder the function of the reinforcing bars arranged in the side groove block main body 3. Set up. The insertion position of the stepping plate 7 is automatically determined by the position of the insertion hole 11 formed in the side groove block body 3 because the insertion portion 11 and the stepping plate insertion convex portion 10 to be inserted are fitted to each other. Come.

      In the illustrated example, two insertion holes 11 correspond to one stepping plate, and there are two insertion holes 11 of the same size and shape for the two stepping plates along the longitudinal direction of the side groove block body 3. There are 4 holes. For example, the stepping plate insertion convex portion 10 that is formed by deeply and widely drilling the insertion hole 11 at the location where the top wall 14 at both ends of the side groove block main body 3 is closed deeply and widely is also inserted into the top wall 14. If it is formed in a suitable shape, one insertion hole 11 drilled near the opening 15 of the top wall 14 at the center of the side groove block main body 3 may be made smaller or omitted together with the stepping plate insertion convex portion 10. it can.

      The dimensions of the insertion hole 11 correspond to the stepping plate insertion convex portion 10 to be fitted. In particular, the insertion depth into the side wall 6 is the width of the receiving surface 8 of the receiving block portion 9 and the side groove block main body 3. It is preferable to consider the strength of the side wall 6 and the reinforcing bars arranged in the side groove block main body 3 and to arrange reinforcing reinforcing bars around the insertion hole 11.

      The number, size, shape, position, and drilling direction of the insertion holes 11 are the above, the characteristics of the side groove block 1, the characteristics of the stepping plate 7, the structure in which the stepping plate 7 is placed on the receiving surface 8, and the paving work. It is optimal in relation to the workability of the construction, the manufacturability of the side groove block 1 and the maintenance management of the stepping plate 7 and the like.

      The tread plate 7 has a flat plate shape and is made of synthetic resin, metal, concrete, reinforced concrete, fiber reinforced concrete, or the like. Further, the length of the width (the length from the side groove block 3 side end portion of the stepping plate 7 to the end portion of the flat plate portion 26) is expected to be about 100 cm, but the shape (planar shape of the stepping plate 7 and the stepping plate 7) Installation of through holes 25 in the plate 7), dimensions (vertical length, horizontal length, thickness), material (synthetic resin, metal, concrete, reinforced concrete, fiber reinforced concrete, etc.), type of structure (Elastic structure, rigid structure), a structure (movable structure, hinge structure, fixed structure) in which the stepping plate 7 is placed on the receiving surface 8 is the size of the load loaded on the stepping plate 7 and the characteristics of the side groove block 1 In relation to the characteristics of the receiving surface 8 of the receiving block part 9 (shape, dimensions, position from the top surface 5 of the top wall), pavement workability, side groove block 1 manufacturability, maintenance management of the tread plate 7, etc. It shall be optimal. The exemplary footplate is made of metal.

      Since the side groove block main body 3 and the pavement 12 have a structure in which an automobile load or the like is shared and supported via the stepping plate 7, appropriate elasticity and rigidity are given to the stepping plate 7. . The illustrated stepping plate 7 that inserts the stepping plate insertion convex portion 10 into the insertion hole 11 of the side groove block main body 3 is made of a metal having a flat plate shape and appropriate elasticity and rigidity. In the case where the insertion hole 11 is formed in the side wall 6 from the side wall outer surface 4 toward the bottom wall 20 of the side groove block main body 3, a synthetic resin stepping plate 7 having excellent flexibility is desirable.

      In the illustrated example, two side plates 7 having the same size and shape correspond to one side groove block main body 3. The number may be one or three or more. Each stepping plate 7 is provided with two stepping plate insertion convex portions 10 at the end portion on the side to be put on the receiving surface 8 of the receiving block portion 9, followed by a substantially rectangular shape having a flat plate portion 26. It has a planar shape. The flat plate portion 26 of the stepping plate 7 installed in the illustrated pavement portion 12 does not have the through hole 25 opened in the front and back directions, but the flat plate portion 26 has appropriate elasticity and rigidity for the stepping plate 7. Within a range, a circular plate, an elliptical shape, a square shape, a diamond shape, a triangular shape and the like may be formed in a perforated plate shape in which the flat plate portion 26 is provided with the through holes 25.

      In the illustrated side groove block main body 3, a total of four insertion holes 11 having the same dimensions and shape are drilled so that the tread plate insertion convex portions 10 for two tread plates are inserted. Also, the two adjacent foot plates 7 are connected to each other via two connecting tools 27. The number of the connecting tools 27 may be one or three or more. The tread plate 7 may be installed so as to bridge the side groove block main bodies 3 adjacent to each other.

      It is not necessary for all of the tread plate insertion convex portions 10 to have the same size and shape. For example, the tread plate insertion convex portion 10 to be inserted into a place where the top walls 14 at both ends of the side groove block main body 3 are closed is formed to be wide and large. In addition, if the insertion hole 11 is also formed into a shape corresponding to the insertion hole 11 and fitted to each other, one of the tread plate insertion convex portions 10 formed in the vicinity of the opening 15 of the top wall 14 at the center portion of the side groove block main body 3 is The insertion hole 11 can be made smaller or omitted. In the illustrated example, two stepping plates 7 correspond to one gutter block main body 3, but the number thereof may be one or three or more.

      In the illustrated example, two insertion holes 11 correspond to one stepping plate, and there are two insertion holes 11 of the same size and shape along the longitudinal direction of the side groove block main body 56. There are 4 holes. For example, the stepping plate insertion convex portion 10 is formed by deeply and widely drilling the insertion hole 11 where the top wall 14 at both ends of the side groove block main body 56 is closed in the top wall 14. If it is formed in a shape suitable for it, the one insertion hole 11 drilled near the opening 15 of the top wall 14 at the center of the side groove block main body 56 may be made smaller or omitted together with the stepping plate insertion convex portion 10. it can.

      The size of the insertion hole 11 corresponds to the stepping plate insertion convex portion 10 to be fitted. In particular, the insertion depth into the side wall 6 is the width of the receiving surface 8 of the receiving block 57 and the side wall of the side groove block main body 56. It is desirable to consider the strength of No. 6 and the reinforcing bars arranged in the side groove block main body 56 and to arrange the reinforcing reinforcing bars around the insertion hole 11.

      In addition to the above, the number, size, shape, position and drilling direction of the insertion holes 11 are the characteristics of the side groove block 55, the characteristics of the stepping plate 7, the structure in which the stepping plate 7 is placed on the receiving surface 8, and the paving work. It is optimal in relation to the workability of the construction and the maintenance management of the stepping plate 7 and the like.

      The tread plate 7 has a flat plate shape and is made of synthetic resin, metal, concrete, reinforced concrete, fiber reinforced concrete, or the like. Further, the width (the length from the end of the side groove block 56 on the side groove block 56 side to the end of the flat plate portion 26) is expected to be about 100 cm, but the shape (the planar shape of the stepping plate 7, the stepping plate 7) Installation of through holes 25 in the plate 7), dimensions (vertical length, horizontal length, thickness), material (synthetic resin, metal, concrete, reinforced concrete, fiber reinforced concrete, etc.), type of structure (Elastic structure, rigid structure), the structure (movable structure, hinge structure, fixed structure) in which the stepping plate 7 is placed on the receiving surface 8 is the size of the load loaded on the stepping plate 7, the characteristics of the side groove block 55 The receiving surface 8 of the receiving block 57 is optimal in relation to the characteristics (shape, dimensions, position from the top surface 5 of the top wall), the workability of the paving work, the maintenance management of the stepping plate 7, and the like. The exemplary footplate is made of metal.

      The side groove block main body 56 and the pavement 12 have a structure in which an automobile load or the like is shared and supported via the stepping plate 7, so that the stepping plate 7 has appropriate elasticity and rigidity. . The illustrated stepping plate insertion convex portion 10 for inserting the stepping plate insertion convex portion 10 into the insertion hole 11 of the side groove block body 56 is made of a metal having a flat plate shape and appropriate elasticity and rigidity. In addition, when the insertion hole 11 is drilled in the side wall 6 from the side wall outer surface 4 toward the bottom wall 20 of the side groove block main body 56, the synthetic resin stepping plate 7 having excellent flexibility is desirable.

      In the illustrated example, two side plates 7 having the same size and shape correspond to one side groove block main body 56. The number may be one or three or more. Each stepping plate 7 is provided with two stepping plate insertion convex portions 10 at the end portion on the side where the receiving block 57 is put on the receiving surface 8, followed by a substantially rectangular plane having a flat plate portion 26. It has a shape. The flat plate portion 26 of the stepping plate 7 installed in the illustrated pavement portion 12 does not have the through hole 25 opened in the front and back directions, but the flat plate portion 26 has appropriate elasticity and rigidity for the stepping plate 7. Within a range, a circular plate, an elliptical shape, a square shape, a diamond shape, a triangular shape and the like may be formed in a perforated plate shape in which the flat plate portion 26 is provided with the through holes 25.

      A total of four insertion holes 11 having the same size and shape are formed in the illustrated side groove block main body 56 so that the tread plate insertion convex portions 10 for two tread plates are inserted. Also, the two adjacent foot plates 7 are connected to each other via two connecting tools 27. The number of the connecting tools 27 may be one or three or more. The tread plate 7 may be installed so as to span the adjacent side groove block main bodies 56 to be connected.

      It is not necessary for all of the tread plate insertion convex portions 10 to have the same size and shape. For example, the tread plate insertion convex portion 10 to be inserted into a place where the top wall 14 at both ends of the side groove block main body 56 is closed is formed to be wide and large. In addition, if the insertion hole 11 is also formed in a shape corresponding to the insertion hole 11 and fitted to each other, one of the tread plate insertion convex portions 10 formed in the vicinity of the opening 15 of the top wall 14 at the center portion of the side groove block main body 56 is The insertion hole 11 can be made smaller or omitted. In the illustrated example, two of the stepping plates 7 correspond to one gutter block main body 56, but the number thereof may be one or three or more.

      When the stepping plate 7 is placed on the receiving surface 8 with a movable structure, an elongated movable groove 30 extends from the vicinity of the front end of the stepping plate insertion convex portion 10 to the flat plate portion 26 of the stepping plate 7 so that the stepping plate 7 faces in the front and back direction. It is drilled to penetrate.

      The side plate 28 of the tread plate insertion convex portion 10 may be formed in a wave shape or the like so that the tread plate insertion convex portion 10 has a friction pulling resistance with the insertion hole 11.

      The illustrated stepping plate 7 is installed at the boundary between the pavement layer 23 and the roadbed 24. The stepping plate insertion convex portion 10 is inserted into the insertion hole 11 of the side groove block main body 56, and the end portion 40 of the stepping plate 7 following the stepping plate insertion convex portion 10 is, for example, the receiving surface of the receiving block 57. 8 is mounted as a movable structure. Thereafter, the flat plate portion 26 of the tread plate 7 is installed at a boundary portion between the pavement layer 23 and the roadbed 24 substantially parallel to the pavement surface 13. The tread plate 7 is installed across the three surfaces of the bottom surface 29 of the insertion hole 11 of the side groove block main body 56, the receiving surface 8 of the receiving block 57, and the installation surface of the pavement 12.

      Since the illustrated stepping plate 7 is installed at the boundary between the pavement layer 23 and the roadbed 24, a sheet 36 for preventing the pavement layer 23 and the stepping plate 7 from adhering to each other is provided on the upper portion of the stepping plate 7. Further, sand 37 is spread on the sheet 36.

      Since the stepping plate 7 is structured to be detachable from the side groove block main body 56, the material made of a metal material such as the stepping plate 7, the metal rod 31, the bolt 33, the insert nut 34, etc. is not easily rusted. It is desirable to use rust prevention treatment. Further, it is desirable to update the pavement plate 7 and the like by judging the degree of deterioration when repairing the pavement 12 at the boundary between the side groove block main body 56 and the pavement 12.

      An example of the movable structure in which the stepping plate 7 is placed on the receiving surface 8 will be described. An elongate movable groove 30 is drilled from the vicinity of the tip of the stepping plate insertion convex portion 10 to the flat plate portion 26 of the stepping plate 7 so as to penetrate the stepping plate 7 in the front and back direction. The stepping plate insertion convex portion 10 is inserted into the insertion hole 11, the end 40 of the stepping plate 7 following the stepping plate insertion convex portion 10 is placed on the receiving surface 8 of the receiving block 57, and the flat plate portion 26 is paved. 12 is further inserted into the end of the movable groove 30 on the pavement side. Thereafter, the metal bar 31 is driven vertically into the pavement 12 along the side of the pavement of the receiving block 57, and the tread plate 7 is inserted into the bottom surface 29 of the insertion hole 11, the receiving surface 8 of the receiving block 57, and the pavement 12. Fix it so that it covers the three installation surfaces. The upper end of the metal bar 31 has a protruding bar 32 bent at a right angle, and the lower end is needle-shaped.

      The tread plate 7 is guided by the metal rod 31 within the length of the movable groove 30 according to the sinking of the pavement 12 at the boundary between the side groove block main body 56 and the pavement 12, and the bottom surface of the insertion hole 11. 29, The receiving block 8 of the receiving block 57 and the installation surface of the pavement 12 are displaced while sliding. When the horizontal displacement of the tackle plate 7 reaches a horizontal displacement amount determined from the length of the movable groove 30, the metal rod 31 temporarily restrains the horizontal displacement, but the horizontal displacement amount determined from the length of the movable groove 30 is reduced. If it exceeds, the metal rod 31 will be pushed by the foot plate 7, and will fall to the pavement part 12 side, and the foot plate 7 will fall to the pavement part 12 from the receiving surface 8 of the receiving block 57. After falling off, the influence of the horizontal displacement of the stepping plate 7 does not reach the side groove block main body 56. The side groove block main body 56 is inclined or damaged by the side groove block protecting function by the movable structure of the stepping plate 7 is smaller than in the case of the hinge structure or the fixed structure.

      An example of a hinge structure on which the tread plate 7 is placed on the receiving surface 8 will be described with reference to FIG. An insert nut 34 for attaching a bolt 33 that functions as a hinge is embedded in the receiving surface 8 of the receiving block 57 when the receiving block 57 is manufactured. A hinge hole 41 for inserting a bolt 33 that functions as a hinge is formed slightly larger than the diameter of the bolt 33 at the end 40 of the pedal plate 7 following the convex plate insertion convex portion 10. The stepping plate 7 placed on the receiving surface 8 of the receiving block 57 is passed through the bolt 33 that functions as a hinge through the hinge hole 41, and a slight margin is provided between the upper surface of the stepping plate 7 and the bolt head. It is attached to the insert nut 34 by bolting so as to have it.

      An example of a fixing structure in which the tread plate 7 is placed on the receiving surface 8 will be described with reference to FIG. An insert nut 34 for attaching the stepping plate 7 with a fixed structure is embedded in the receiving surface 8 of the receiving block 57 when the receiving block 57 is manufactured. A bolt hole 35 for fixing and attaching the stepping plate 7 is formed in the end portion 40 of the stepping plate 7 subsequent to the stepping plate insertion convex portion 10. The tread plate 7 placed on the receiving surface 8 of the receiving block 57 is attached to the insert nut 34 by bolting so as to be fixed to the receiving surface 8 of the receiving block 57 by the bolt 33.

      For example, the situation of construction when the gutter block 55 is buried in connection with the boundary between the sidewalk 38 and the roadway 39 and a continuous drainage channel 2 for draining rainwater or the like is constructed will be described. The gutter block main body 56 is usually constructed at the boundary between the sidewalk 38 and the roadway 39 prior to the sidewalk 38 and the roadway 39. The gutter block main body 56 is installed so that the top wall top surface 5 is at the same height as the pavement surface 13 of the roadway 39. After the gutter block main body 56 is installed at a position and height based on the road plan, a receiving block 57 manufactured separately at the factory is installed in contact with the gutter block main body 56, or the gutter block main body 56 is installed. The receiving block 57 is manufactured by placing concrete on the construction site so as to abut against. Thereafter, the sidewalk 38 and the paved portion 12 of the roadway 39 are constructed.

Thereafter, the metal bar 31 is inserted into the movable groove 30 of the stepping plate 7, the metal bar 31 is driven vertically into the pavement portion 12 along the side surface of the pavement portion of the receiving block 57, and the stepping plate 7 is inserted into the bottom surface of the insertion hole 11. 29. Fixing is carried out so as to span the three surfaces of the receiving surface 8 of the receiving block 57 and the installation surface of the pavement 12. Since the foot plate 7 has a structure that can be attached to and detached from the side groove block main body 56, a material made of a metal material such as the foot plate 7 and the metal rod 31 is made of a material that does not easily rust or has a rust prevention treatment. Apply. Since the stepping plate 7 is installed at the boundary between the pavement layer 23 and the roadbed 24, a sheet 36 for preventing the pavement layer 23 and the stepping plate 7 from adhering to each other is provided on the upper portion of the stepping plate 7. Further, sand 37 is distributed on the sheet 36. After the installation of the stepping plate 7 or the like is completed, the pavement layer 23 is constructed.

A hinge hole 41 for inserting a bolt 33 that functions as a hinge is formed in the end portion 40 of the tread plate 47 slightly larger than the diameter of the bolt 33. The stepping plate 47 placed on the receiving surface 8 of the notch receiving portion 82 is passed through the bolt 33 that functions as a hinge through the hinge hole 41, and there is some margin between the upper surface of the stepping plate 47 and the bolt head. The insert nut 34 is bolted and attached so as to have a space.

      An example of a fixing structure in which the tread plate 47 is placed on the receiving surface 8 will be described with reference to FIG. An insert nut 34 for attaching the stepping plate 47 with a fixed structure is embedded in the receiving surface 8 of the notch receiving portion 82 when the gutter block main body 86 is manufactured. A bolt hole 35 for fixing and mounting the stepping plate 47 is formed in the end portion 40 of the stepping plate 47. The stepping plate 47 placed on the receiving surface 8 of the notch receiving portion 82 is bolted to the insert nut 34 so as to be fixed to the receiving surface 8 of the notch receiving portion 82 by the bolt 33.

      For example, the situation of construction when the gutter block 85 is buried in connection with the boundary between the sidewalk 38 and the roadway 39 of the road and a continuous drainage channel 2 for draining rainwater or the like is constructed will be described. The gutter block main body 86 is usually constructed at the boundary between the sidewalk 38 and the roadway 39 before the sidewalk 38 and the roadway 39. The gutter block main body 86 is installed so that the top wall upper surface 5 is at the same height as the pavement surface 13 of the roadway 39. After the gutter block main body 86 is installed at the position and height based on the road plan, the sidewalk 38 and the pavement 12 of the roadway 39 are constructed. The construction of the pavement 12 at the boundary between the side groove block main body 86 and the pavement 12 needs to be carefully performed even when there are restrictions on the use of large heavy machinery. The position of the receiving surface 8 of the notch receiving portion 82 from the top surface 5 of the gutter block main body 86 is provided at the boundary between the pavement layer 23 and the roadbed 24. After the roadbed 24 is constructed to the same height as the receiving surface 8, the end 40 of the stepping plate 47 is notched and placed on the receiving surface 8 of the seating portion 82, and then the flat plate portion 26 of the stepping plate 47 is paved. It is installed at the boundary between the pavement layer 23 and the roadbed 24 substantially parallel to the surface 13. Thereafter, the metal rod 31 is inserted into the movable groove 30 of the stepping plate 47, and the metal rod 31 is driven vertically into the pavement portion 12 along the side of the pavement portion of the notch receiving portion 82, so that the stepping plate 47 is cut out. Fixing is performed so as to span the two surfaces of the receiving surface 8 of the seat portion 82 and the installation surface of the pavement portion 12. Since the tread plate 47 is structured to be detachable from the side groove block main body 86, a material made of a metal material such as the tread plate 47 and the metal rod 31 is made of a material that does not easily rust or has a rust prevention treatment. Apply. Since the stepping plate 47 is installed at the boundary between the pavement layer 23 and the roadbed 24, a sheet 36 for preventing the pavement layer 23 and the stepping plate 47 from adhering to each other is placed over the stepping plate 47. Further, sand 37 is distributed on the sheet 36. After the installation of the stepping plate 47 and the like is completed, the pavement layer 23 is installed.

      When the gutter block 85 is installed at the boundary between the sidewalk 38 and the roadway 39 of the road and the use of the road is started, an automobile load or the like is loaded on the pavement 12 at the boundary between the gutter block main body 86 and the pavement 12. Become. Since the stepping plate 47 is installed across two surfaces of the receiving surface 8 of the notch receiving portion 82 and the installation surface of the pavement portion 12, the loaded automobile load or the like is applied to the side groove block main body 86 through the stepping plate 47. And the pavement 12 share and support each other. Appropriate elasticity and rigidity are imparted to the tread plate 47. For this reason, the tread plate 47 resists the sinking of the pavement portion 12 at the boundary portion caused by the loading of an automobile load or the like, and further follows the deformation / displacement of the pavement portion 12 to follow the deterioration / sinking of the pavement portion 12 and the boundary. Subsidence that suppresses / reduces the sinking of the part of the pavement 12 with a vertical step with respect to the gutter block main body 86 and, at the same time, smoothly sinks the shape of the subsidence toward the pavement central part of the road, etc. Can be controlled as.

      The side groove block 85 has the function of suppressing / reducing deterioration and subsidence of the pavement 12 and the shape control function of the subsidence, thereby causing deterioration of the lane line, poor drainage of rainwater stored in the pavement layer 23 depression, and the side groove block main body 86. It is possible to suppress and reduce the occurrence of serious fall accidents, water splashes, noise, vibration, etc. that occur when a two-wheeled vehicle running in a depression with a step perpendicular to the wheel is taken off. While ensuring smooth driving, it is possible to provide safety and security to the local residents. Further, since the pavement portion 12 leads to a longer pavement repair cycle period, it is extremely effective in reducing the burden of pavement repair work costs and improving construction investment efficiency.

      Next, a gutter block 90 according to a ninth embodiment of the present invention will be described with reference to the drawings.

      33 to 35 relate to the ninth embodiment of the present invention, FIG. 33 is a perspective view showing an example of the side groove block 90, and FIG. 34 is a structure in which the tread plate insertion convex portion 10 is movable in the insertion hole 11. 35 is a longitudinal sectional view showing an example of the side groove block 90 having a form to be inserted, FIG. 35A is a plan view of an example of the stepping plate 7 provided with the through holes 25, and FIG. FIG. 35C is a plan view of an example of the stepping plate 7 in which one stepping plate 7 corresponds to one side groove block main body 91.

      The side groove block 90 is a side groove block 90 made of, for example, a side groove block with a beam, for drainage of rainwater or the like embedded in a road or the like. The side groove block 90 includes a side groove block main body 91, an insertion hole 11 formed in the side wall 6 from the side wall outer surface 4 of the side groove block main body 91, and a stepping plate 7 in which the stepping plate insertion convex portion 10 is inserted into the insertion hole 11. And. The tread plate 7 is installed across the bottom surface 29 of the insertion hole 11 and the installation surface of the pavement 12, and an automobile load or the like is loaded on the pavement 12 at the boundary between the side groove block main body 91 and the pavement 12. The side groove block main body 91 and the pavement 12 are configured to share and support each other via the tread plate 7.

      The side groove block main body 91 and the insertion hole 11 are made of concrete, and are manufactured integrally. The illustrated gutter block main body 91 has the drainage channel 2 and has a rectangular cross-sectional shape. The central top wall 14 in the longitudinal direction is an opening, and the top wall 14 is closed at both ends. It has a cross-sectional shape. The opening 15 of the top wall 14 can be fitted with a plurality of concrete or steel groove lids 16 so as to be detachable like a conventional U-shaped groove block. The places where the top walls 14 at both ends of the side groove block main body 91 are closed have a combined length of approximately one half of the total length, and function as a beam in the upper part of the side groove block main body 91.

      At the end of the top wall 14 on the side of the side groove block main body 91 where the stepping plate 7 is not installed, there is provided a block mounting portion 18 on which a part of the lower surface of the walkway boundary block 17 is mounted and fixed. The walking road boundary block 17 is placed and fixed on the placing portion 18.

      The insertion hole 11 into which the tread plate insertion convex portion 10 is inserted is substantially parallel to the top surface 5 of the side groove block main body 91 in the longitudinal direction of the side wall 6 from the side wall outer surface 4 to the side wall 6 both vertically and horizontally. In addition, it is made slightly larger than the cross section of the tread plate insertion convex portion 10. In some cases, the vertical direction may be formed in the side wall 6 from the side wall outer surface 4 toward the bottom wall 20 of the side groove block main body 91. The shape of the entrance portion of the insertion hole 11 is the same cross-sectional shape as the stepping plate insertion convex portion 10 to be inserted, and the insertion hole 11 is drilled so as not to hinder the reinforcing bar function arranged in the side groove block main body 91. Set up. Since the insertion hole 11 and the stepping plate insertion convex portion 10 to be inserted are fitted to each other, the installation position of the stepping plate 7 is automatically determined by the position of the insertion hole 11 formed in the side groove block main body 91. Come.

      In the illustrated example, two insertion holes 11 correspond to one stepping plate, and there are two insertion holes 11 of the same size and shape along the longitudinal direction of the side groove block main body 91. There are 4 holes. For example, the stepping plate insertion convex portion 10 is formed by deeply and widely drilling the insertion hole 11 where the top wall 14 at both ends of the side groove block main body 91 is closed deeply and widely in the top wall 14. If it is formed in a shape suitable for it, one insertion hole 11 drilled near the opening 15 of the top wall 14 at the center of the side groove block main body 91 may be made smaller or omitted together with the stepping plate insertion convex portion 10. it can.

      The dimension of the insertion hole 11 corresponds to the stepping plate insertion convex portion 10 to be fitted, and in particular, the insertion depth into the side wall 6 corresponds to the vertical step sinking of the pavement portion 12 with respect to the side groove block main body 91. It is appropriate for the horizontal displacement amount of the tread plate 7 and is optimum in consideration of the strength of the side wall 6 of the side groove block main body 91, the reinforcing bars arranged in the side groove block main body 91, and the like. It is desirable to arrange reinforcing bars around the insertion hole 11. Further, a roundness 92 is provided at the lower part of the entrance portion of the insertion hole 11.

      The position of the insertion hole 11 from the top surface 5 of the side groove block main body 91 is provided at the boundary portion between the pavement layer 23 and the roadbed 24, but may be a position to become the pavement layer 23 or the roadbed 24.

      Further, the number, size, shape, position, and drilling direction of the insertion holes 11 are the characteristics of the side groove block 90, the characteristics of the stepping plate 7, the workability of the paving work, the manufacturability of the side groove block 90, the stepping plate 7, etc. It shall be optimal in relation to maintenance management.

      The tread plate 7 has a flat plate shape and is made of synthetic resin, metal, concrete, reinforced concrete, fiber reinforced concrete, or the like. Further, the length of the width (the length of the side plate 7 from the side groove block main body 91 side end to the end of the flat plate portion 26) is expected to be about 100 cm. Installation of through holes 25 in the plate 7), dimensions (vertical length, horizontal length, thickness), material (synthetic resin, metal, concrete, reinforced concrete, fiber reinforced concrete, etc.), type of structure (Elastic structure, rigid structure) are the magnitude of the load loaded on the stepping plate 7, the characteristics of the side groove block 90, the position of the insertion hole 11 from the top surface 5 of the ceiling, the workability of the paving work, the side groove block 90 It shall be optimal in relation to manufacturability and maintenance of the stepping plate 7. The illustrated foot plate 7 is made of metal.

      Since the side groove block main body 91 and the pavement 12 have a structure in which an automobile load and the like are shared and supported via the stepping plate 7, appropriate elasticity and rigidity are given to the stepping plate 7. . The illustrated stepping plate 7 for fitting the stepping plate insertion convex portion 10 into the insertion hole 11 of the side groove block main body 91 is made of a metal having a flat plate shape and appropriate elasticity and rigidity. In addition, when the insertion hole 11 is drilled in the side wall 6 from the side wall outer surface 4 toward the bottom wall 20 of the side groove block main body 91, the synthetic resin stepping plate 7 having excellent flexibility is desirable.

      In the illustrated example, two side plates 7 having the same size and shape correspond to one gutter block main body 91. The number may be one or three or more. Each stepping plate 7 has a two-step stepping plate insertion convex portion 10 at one end portion of the stepping plate 7 and has a substantially rectangular planar shape having a flat plate portion 26 subsequently. The flat plate portion 26 of the stepping plate 7 installed in the illustrated pavement portion 12 does not have the through hole 25 opened in the front and back directions, but the flat plate portion 26 has appropriate elasticity and rigidity for the stepping plate 7. Within a range, a circular plate, an elliptical shape, a square shape, a diamond shape, a triangular shape and the like may be formed in a perforated plate shape in which the flat plate portion 26 is provided with the through holes 25.

      In the illustrated side groove block main body 91, a total of four insertion holes 11 having the same size and shape are drilled so that the tread plate insertion convex portions 10 for two tread plates are inserted. Also, the two adjacent foot plates 7 are connected to each other via two connecting tools 27. The number of the connecting tools 27 may be one or three or more. The tread plate 7 may be installed so as to bridge the side groove block main bodies 91 adjacent to each other.

      It is not necessary for all of the tread plate insertion convex portions 10 to have the same size and shape. For example, the tread plate insertion convex portion 10 to be inserted into a place where the top wall 14 at both ends of the side groove block main body 91 is closed is formed wide and large. In addition, if the insertion hole 11 is also formed in a shape corresponding to it and fitted to each other, one of the tread plate insertion protrusions 10 formed in the vicinity of the opening 15 of the top wall 14 at the center portion of the side groove block main body 91 is The insertion hole 11 can be made smaller or omitted. In the illustrated example, two of the stepping plates 7 correspond to one gutter block main body 91, but the number thereof may be one or three or more.

      Since the stepping plate insertion convex portion 10 is inserted into the insertion hole 11 for inserting the stepping plate insertion convex portion 10 as a movable structure, from the vicinity of the tip of the stepping plate insertion convex portion 10 to the flat plate portion 26 of the stepping plate 7, An elongated movable groove 30 is formed so as to penetrate the tread plate 7 in the front and back direction.

      The side plate 28 of the tread plate insertion convex portion 10 may be formed in a wave shape or the like so that the tread plate insertion convex portion 10 has a friction pulling resistance with the insertion hole 11.

      The illustrated stepping plate 7 is installed at the boundary between the pavement layer 23 and the roadbed 24. The stepping plate insertion convex portion 10 is inserted into the insertion hole 11 of the side groove block main body 91 as a movable structure, and then the flat plate portion 26 of the stepping plate 7 is substantially parallel to the pavement surface 13, and the pavement layer 23 and the roadbed 24 Installed at the border. The tread plate 7 is installed across the two surfaces of the bottom surface 29 of the insertion hole 11 of the gutter block main body 91 and the installation surface of the pavement 12.

      Since the illustrated stepping plate 7 is installed at the boundary between the pavement layer 23 and the roadbed 24, a sheet 36 for preventing the pavement layer 23 and the stepping plate 7 from adhering to each other is provided on the upper portion of the stepping plate 7. Further, sand 37 is spread on the sheet 36.

      Since the foot plate 7 can be attached to and detached from the side groove block main body 91, a member made of a metal material such as the foot plate 7 and the metal rod 31 is made of a material that does not easily rust, or is rust-proof. It is desirable to perform processing. Further, it is desirable to update the pavement plate 7 and the like by judging the degree of deterioration when repairing the pavement 12 at the boundary between the side groove block main body 91 and the pavement 12.

      An example of a movable structure in which the tread plate insertion convex portion 10 is inserted into the insertion hole 11 as a movable structure will be described. An elongate movable groove 30 is drilled from the vicinity of the tip of the stepping plate insertion convex portion 10 to the flat plate portion 26 of the stepping plate 7 so as to penetrate the stepping plate 7 in the front and back direction. The stepping plate insertion convex portion 10 is inserted into the insertion hole 11, and the subsequent stepping plate 7 in which the flat plate portion 26 is installed in the pavement portion 12 is further provided with a metal rod 31 at the flat plate portion side end of the movable groove 30. Is inserted. Thereafter, the metal rod 31 is driven vertically into the pavement 12 along the side wall outer surface 4 of the gutter block main body 91, and the tread plate 7 is hung over two surfaces of the bottom surface 29 of the insertion hole 11 and the installation surface of the pavement 12. To fix. The upper end of the metal bar 31 has a protruding bar 32 bent at a right angle, and the lower end is needle-shaped.

      The tread plate 7 is guided to the metal rod 31 within the range of the length of the movable groove 30 according to the sinking of the pavement 12 at the boundary between the side groove block main body 91 and the pavement 12, and the bottom surface of the insertion hole 11. 29, It will displace while sliding on the installation surface of the pavement 12. When the horizontal displacement of the tackle plate 7 reaches a horizontal displacement amount determined from the length of the movable groove 30, the metal rod 31 temporarily restrains the horizontal displacement, but the horizontal displacement amount determined from the length of the movable groove 30 is reduced. If it exceeds, the metal bar 31 will be pushed by the foot plate 7, and will fall to the pavement part 12 side, and the foot plate 7 will fall to the pavement part 12 from the bottom face 29 of the insertion hole 11. After dropping off, the influence of the horizontal displacement of the stepping plate 7 does not reach the side groove block main body 91. Due to the side groove block protection function by the movable structure of the stepping plate 7, the side groove block main body 91 is less likely to be inclined or damaged.

The position of the insertion hole 11 from the top wall upper surface 5 of the side groove block main body 91 is provided at the boundary between the pavement layer 23 and the roadbed 24. After the roadbed 24 is constructed to the same height as the bottom surface 29 of the insertion hole 11, the stepping plate insertion convex portion 10 is inserted into the insertion hole 11 of the side groove block main body 91, and subsequently, the flat plate portion 26 of the stepping plate 7 is paved. It is installed at the boundary between the pavement layer 23 and the roadbed 24 substantially parallel to the surface 13. Thereafter, the metal rod 31 is inserted into the movable groove 30 of the stepping plate 7, the metal rod 31 is driven vertically into the pavement portion 12 along the side wall outer surface 4 of the side groove block main body 91, and the stepping plate 7 is inserted into the insertion hole 11. Fixing is performed so as to span the two surfaces of the bottom surface 29 and the installation surface of the pavement 12. Since the stepping plate 7 has a structure that can be attached to and detached from the side groove block main body 91, a member made of a metal material such as the stepping plate 7 and the metal rod 31 is made of a material that does not easily rust or has a rust prevention treatment. Apply. Since the stepping plate 7 is installed at the boundary between the pavement layer 23 and the roadbed 24, a sheet 36 for preventing the pavement layer 23 and the stepping plate 7 from adhering to each other is provided on the upper portion of the stepping plate 7. Further, sand 37 is distributed on the sheet 36. After the installation of the stepping plate 7 or the like is completed, the pavement layer 23 is constructed.

      When the gutter block 90 is installed at the boundary between the sidewalk 38 and the roadway 39 of the road and the use of the road is started, an automobile load or the like is loaded on the pavement 12 at the boundary between the gutter block main body 91 and the pavement 12. Become. Since the stepping plate 7 is installed across the bottom surface 29 of the insertion hole 11 and the installation surface of the pavement 12, the loaded automobile load and the like are passed through the side plate 7 and the side groove block main body 91 and the pavement 12. Will share and support each other. Appropriate elasticity and rigidity are given to the tread plate 7. For this reason, the stepping plate 7 resists the sinking of the pavement 12 at the boundary portion caused by the loading of an automobile load or the like, and further follows the deformation / displacement of the pavement portion 12 to follow the deterioration / sinking of the pavement 12 and the boundary. The subsidence of the pavement 12 of the part is suppressed / reduced with a vertical step with respect to the gutter block main body 91, and the subsidence is smoothly rubbed toward the central part of the pavement such as a road. Can be controlled as.

      The side groove block 90 has a function of suppressing / reducing deterioration and subsidence of the pavement 12 and a shape control function of the subsidence, thereby causing deterioration of lane lines, poor drainage of rainwater stored in the pavement layer 23 depression, and side groove block main body 91. It is possible to suppress and reduce the occurrence of serious fall accidents, water splashes, noise, vibration, etc. that occur when a two-wheeled vehicle running in a depression with a step perpendicular to the wheel is taken off. While ensuring smooth driving, it is possible to provide safety and security to the local residents. Further, since the pavement portion 12 leads to a longer pavement repair cycle period, it is extremely effective in reducing the burden of pavement repair work costs and improving construction investment efficiency.
