Description

The present invention relates to an installation structure and an installation method for suppressing the removal of the buried member in a configuration in which a buried member such as an anchor nut is fixed to a drainage pavement provided with a water-permeable surface layer.

In general, as a pavement body having a water-permeable surface layer in which voids for water permeability are formed, a pavement body having a surface layer formed of a mixture of aggregate and asphalt is known.

Conventionally, as such a pavement, a functional pavement having improved strength and the like has been proposed by injecting a slurry containing a functional material and exhibiting a reinforcing effect into the voids of the surface layer and solidifying the slurry. (See, for example, Patent Document 1).

Similarly, in order to improve the strength of the pavement, a road pavement method in which the surface of the pavement is filled and coated with a non-permeable reinforcing material has been proposed (see, for example, Patent Document 2).

Further, as the material to be injected in this way, it is disclosed that a material for preventing a decrease in rigidity or a material having a specific hardness is used (see, for example, Patent Document 4).

By the way, in a roadway using such a pavement, a structure such as a shock absorber or a pole for separating lanes is provided on the pavement, and the structure is fixed to the pavement. It is necessary to provide an embedded member such as an anchor nut. In such a case, the buried member such as an anchor nut is hardened by providing the buried member in the hole drilled in the pavement and filling the gap between the hole and the buried member with a fixing material such as cement mortar or adhesive. It was fixed to the pavement by letting it.

However, structures such as cushioning bodies and poles provided on the pavement body via the buried member may collide with a vehicle traveling on the pavement body, and at this time, the buried member may collide with the vehicle. It receives a momentary impact in the horizontal direction through the structure.

Therefore, in the case of ordinary drainage pavement in which voids are formed in the surface layer, the pavement together with the surface layer will peel off when subjected to such a momentary impact from the horizontal direction.

Further, even if the functional pavement is solidified by injecting a slurry containing a functional material and exhibiting a reinforcing effect into the voids of the surface layer as in the conventional functional pavement described in Patent Document 1, the functional pavement is solidified. The body is configured to prevent freezing of the road surface, improve wear resistance against vehicle running, etc., and as a specific configuration, selectively pave the slurry in the upper void while leaving the lower void. Only the configuration for injecting and solidifying is disclosed, and the momentary impact received from the horizontal direction as described above is not taken into consideration. Therefore, a buried member is provided in such a functional pavement to provide a buffer or the like. When a structure is provided, when the cushioning material collides with a vehicle, the entire surface layer of the functional pavement is peeled off.

Even in the case of a pavement in which the surface of the drainage pavement is filled and coated with a non-permeable reinforcing material as in the road pavement method described in Patent Document 2, the structure takes wear resistance into consideration, as described above. Since the momentary impact received from the horizontal direction is not taken into consideration, the entire surface layer will be peeled off.

This is not solved even if the material injected into the void is changed to the one disclosed in the above-mentioned conventional patent documents 3 and 4.

The present invention has been made in view of such circumstances, and in a configuration in which a buried member such as an anchor nut is fixed to a drainage pavement provided with a water-permeable surface layer, an installation structure and installation for suppressing the removal of the buried member.

Hereinafter, embodiments according to the present invention will be described with reference to the drawings.

FIG. 1 shows an outline of the overall configuration of the installation structure of the buried member 1 according to the present invention, and FIGS. 2 to 4 show the installation method of the buried member 1.

The installation structure of the buried member 1 is a structure in which the buried member 1 is installed on a drainage pavement 2 having a water-permeable surface layer 21 in which a gap for water permeability is formed, and the buried member 1 is the surface layer. The surface layer 21 which is housed in the recess 20 formed in the recess 20 and orbits around the recess 20 is formed with a reinforcing portion 3 formed by solidifying the reinforcing material 30 which has flowed into the gap of the surface layer 21. Is what you are doing.

The buried member 1 is an anchor nut that is constructed while being buried in the drainage pavement 2 and is configured so that a structure 4 such as a buffer or a pole provided on the drainage pavement 2 can be fixed after the construction. A member similar to the fixed member is used. The buried member 1 is a fixed member such as an anchor nut for fixing the structure 4 provided on the drainage pavement 2, and if it can be buried in the drainage pavement 2, the diameter and size thereof are particularly high. Is not limited, and various diameters, pitches, and lengths are used.

Drainage pavement 2 is a pavement in which water drainage is improved during rainfall by forming many voids for water permeability, and is basically an asphalt having a porosity of 5 to 25%, preferably 15 to 20%. It is composed of a surface layer 21 made of pavement. The asphalt pavement constituting the surface layer 21 is constructed by laying an asphalt mixture in which an aggregate made of crushed stone or the like is bonded with an asphalt composition. At this time, as the asphalt mixture, a porous asphalt mixture or an open particle asphalt mixture is used. Further, the lower layer of the surface layer 21 may be formed with a base layer 22 made of the same asphalt pavement in which the voids are reduced to eliminate water permeability. As the asphalt composition constituting the base layer 22, a coarse-grained asphalt mixture is used. The thickness of the drainage pavement 2 varies depending on the traffic volume, regional characteristics, durability, location, etc., but the surface layer 21 has a thickness of 20 to 80 mm, more preferably a thickness of 30 to 50 mm, and the base layer 22 has a thickness of 20 to 50 mm. The thickness is 20 to 130 mm, more preferably 30 to 100 mm, and the total thickness of the surface layer 21 and the base layer 22 is 40 to 150 mm, preferably 60 to 150 mm. In the present embodiment, the drainage pavement 2 has a surface layer 21 having a thickness of 40 mm and a base layer 22 having a thickness of 30 mm, and is constructed on the roadbed 5. In the case of a highway or the like, the roadbed 5 may be configured by providing a waterproof sheet 52 on a concrete skeleton 51.

In the present embodiment, the drainage pavement 2 is configured by providing a base layer 22 and a surface layer 21 on a roadbed 5 in which a waterproof sheet 52 is provided on a concrete skeleton 51, but this is a highway or the like. This is because the roadbed 5 is not limited to the one in which the waterproof sheet 52 is provided on the concrete skeleton 51, and may be provided on the ground. Further, although the base layer 22 is provided under the surface layer 21, in a pavement having a small load such as a sidewalk, the drainage pavement 2 may be formed only by the water-permeable surface layer 21.

The drainage pavement 2 is perforated with a recess 20 for providing the above-mentioned buried member 1. The recess 20 is not particularly limited as long as it has a diameter and a depth that can accommodate the entire buried member 1 and fix the buried member 1 in the recess 20, but the diameter is φ56 to 160 mm, more preferably. The diameter is φ65 to 160 mm, and the depth is appropriately determined in the range of the depth from 20 mm or more to the bottom surface of the base layer 22. Regarding the depth of the recess 20, in order to obtain a sufficient reinforcing effect by the reinforcing portion 3, it is preferable that the recess 20 is perforated to a depth on the upper surface of the base layer 22, preferably in the middle of the base layer 22. The buried member 1 is provided in the recess 20, and the buried member 1 is fixed by filling the gap between the two with the fixing member 10 and solidifying the recess 20.

As the fixing material 10 that is filled in the gap between the recess 20 and the buried member 1 provided in the recess 20 and fixes the buried member 1 in the recess 20, the asphalt pavement of the surface layer 21 constituting the recess 20 is used. The adhesive is not particularly limited as long as it can secure the adhesion to the metal constituting the buried member 1, and for example, an adhesive made of a polymer-based material made of a synthetic resin such as an epoxy resin. It may be a cement material such as mortar.

The reinforcing portion 3 is formed by impregnating the surface layer 21 with the reinforcing material 30 so as to orbit the recess 20 in which the buried member 1 is provided and solidifying the reinforcing member 30. As the reinforcing material 30, any material that can reinforce the surface layer 21 by penetrating into the surface layer 21 and solidifying can be used, and a material that solidifies from a liquid can be used. For example, when an adhesive made of a polymer-based material made of a synthetic resin such as an epoxy resin is used for the reinforcing material 30, it is preferable to use one having a glass transition point higher than the summer temperature (70 ° C.) of the asphalt pavement. Further, a cement material such as mortar, which does not have a glass transition point, can also be suitably used as the reinforcing material 30. Further, when the surface layer 21 is impregnated with the reinforcing material 30, the reinforcing material 30 may be impregnated with a viscosity-adjusted material mixed with a filler or the like so as to solidify in a state of being spread over the entire surface layer 21. Examples of the filler include silica, talc, mica, and glass fiber.

The size of the reinforcing portion 3 can be appropriately determined according to the size of the recess 20. Specifically, on the upper surface of the surface layer 21, the reinforcing material 30 is sprayed in a substantially circular range having a size of about 2 to 8 times, more preferably 3 to 6 times the diameter of the recess 20. , It is provided so as to be a reinforcing portion 3 having a substantially columnar size that goes around the recess 20. However, if the reinforcing portion 3 is made too large, the area of the portion of the drainage pavement 2 that impairs the water permeability will be increased. Therefore, the surface of the surface layer 21 is abbreviated as having a diameter of up to φ350 mm. It is provided so as to be cylindrical, preferably substantially cylindrical in the range up to a diameter of φ320 mm. Further, the spraying range of the reinforcing material 30 on the upper surface of the surface layer 21 is not limited to the substantially columnar shape as described above, but the reinforcing material 30 is sprayed so as to include the substantially circular shape range as described above to provide the reinforcing portion 3. It is preferable to form.

The reinforcing material 30 permeates the surface layer 21, but when it reaches the base layer 22 having no water permeability, it does not substantially permeate the base layer 22, so that the boundary portion between the base layer 22 and the surface layer 21, that is, the upper surface of the base layer 22. It spreads radially and solidifies, increasing the anchor effect. The degree of spread can be adjusted by the viscosity of the reinforcing material 30.

Further, the surface layer 21 of the drainage pavement may soften when the asphalt pavement rises near the summer temperature (70 degrees), and the strength of the reinforcing portion 3 may decrease. Therefore, the upper surface of the surface layer 21 is concerned. On the surface portion of the reinforcing portion 3 that is exposed to the surface, a heat insulating layer made of a heat insulating material is provided to prevent the temperature from rising due to the irradiation of direct sunlight and to prevent the asphalt pavement constituting the reinforcing portion 3 from softening. It may be constructed, or the asphalt pavement itself constituting the surface layer 21 may be made of a heat-shielding pavement material.

Next, a method of installing the buried member 1 will be described.
As shown in FIG. 2, first, the reinforcing material 30 is poured over the surface layer 21 of the portion where the buried member 1 is to be provided, and the surface layer 21 is impregnated with the reinforcing material 30.

At this time, as the reinforcing material 30, a reinforcing material 30 whose viscosity is adjusted by adding a filler to the reinforcing material 30 is used according to the degree of impregnation of the surface layer 21. As a result, the reinforcing material 30 permeates the surface layer 21, but it is difficult for the reinforcing material 30 to permeate into the non-permeable base layer 22 under the surface layer 21, so that the reinforcing material 30 permeates the surface of the base layer 22 corresponding to the boundary portion between the base layer 22 and the surface layer 21. As a result, the reinforcing portion 3 is formed by solidifying the mixed layer of the surface layer 21 and the reinforcing material 30 in a state where the projected area in the plan view of the lowermost portion is larger than the projected area in the plan view of the uppermost portion. Will be done.

When forming the reinforcing portion 3, one type of reinforcing material 30 whose viscosity has been adjusted may be infiltrated to form the reinforcing portion 3, or a plurality of types of reinforcing materials 30 adjusted to different viscosities may be formed. It may be permeated to form the reinforcing portion 3. That is, with one type, the lower end is difficult to spread, but if the low-viscosity reinforcing material 30 is infiltrated and spread, and then the high-viscosity reinforcing material 30 is infiltrated, the lowermost end is as shown in FIG. The projected area of the portion in a plan view can be easily formed, the anchor effect can be expected more, and the reinforcing portion 3 can be formed into a desired anchor shape.
After forming the reinforcing portion 3 in this way, as shown in FIG. 2C, the recess 20 is drilled from above the surface layer 21 corresponding to the reinforcing portion 3. At this time, the recess 20 is perforated to a depth extending to the middle of the base layer 22 below the surface layer 21, that is, a depth formed so as to be below the upper surface of the base layer 22.

Then, after the buried member 1 is provided in the recess 20, the gap between the buried member 1 and the recess 20 is filled with a fixing material 10 such as mortar or an adhesive to solidify the buried member 1 in the recess 20. Fix it. Until the fixing material 10 is filled and solidified, the buried member 1 is maintained in a suspended state by a jig (not shown) provided on the drainage pavement 2 so as to be in the fixing material 10. It is constructed so that it will not settle.

According to the installation structure of the buried member 1 configured in this way, the surface layer 21 that circulates around the recess 20 already has a reinforcing portion 3 in which the reinforcing material 30 that has flowed into the voids of the surface layer 21 is solidified. Since it is formed, when the embedded member 1 is fixed in the recess 20, the fixing material 10 filled in the recess 20 is filled in the recess 20 without spreading to the periphery, and is firmly integrated with the reinforcing portion 3. Will be transformed into. Moreover, since the reinforcing portion 3 solidifies in a shape that spreads radially on the surface of the base layer 22 below the surface layer 21, it exerts an anchor effect.

Further, since the fixing material 10 filled in the recess 20 is solidified in the recess 20 without spreading to the surroundings, the liquid level of the fixing material 10 filled during curing does not drop, so that the liquid level does not drop. The buried member 1 can be fixed in the recess 20 without performing the replenishment filling work for the reduced amount.

As a result, as shown in FIG. 2D, the buried member 1 housed in the recess 20 is reinforced by solidifying the periphery of the fixing member 10 that fixes the buried member 1 to the surface layer 21 into a shape having an anchor effect. Since the structure 4 is reinforced by the portion 3, the structure 4 fixed to the buried member 1 exhibits sufficient durability even if it receives a momentary impact from the horizontal direction. Therefore, even if a vehicle traveling on the drainage pavement 2 collides with the structure 4 fixed to the buried member 1, it is possible to prevent the surface layer 21 of the drainage pavement 2 from peeling off. You will be able to do it.

FIG. 3 shows another installation method of the buried member 1.
As shown in FIG. 3B, first, the recess 20 is drilled from above the surface layer 21 of the portion where the buried member 1 is to be provided. At this time, the recess 20 is perforated to a depth extending to the middle of the base layer 22 below the surface layer 21, that is, a depth formed so as to be below the upper surface of the base layer 22.

After the buried member 1 is provided in the recess 20, the gap between the recess 20 is filled with a fixing material 10 such as mortar or an adhesive and solidified to fix the buried member 1 in the recess 20. To do. At this time, since the surface layer 21 around the recess 20 has water permeability, the fixing material 10 is partially impregnated with the surface layer 21, but the viscosity is adjusted so as not to spread as much as possible.

Then, as shown in FIG. 3C, the reinforcing material 30 is poured from above the surface layer 21 so as to orbit around the recess 20, and the surface layer 21 is impregnated with the reinforcing material 30 and solidified to solidify the reinforcing member 3. To form.

Also in this case, the reinforcing material 30 is used in which the viscosity is adjusted by adding a filler to the reinforcing material 30 according to the degree of impregnation of the surface layer 21. As a result, the reinforcing material 30 permeates the surface layer 21, but it is difficult for the reinforcing material 30 to permeate into the non-permeable base layer 22 under the surface layer 21, so that the reinforcing material 30 permeates the surface of the base layer 22 corresponding to the boundary portion between the base layer 22 and the surface layer 21. As a result, the reinforcing portion 3 is formed by solidifying the mixed layer of the surface layer 21 and the reinforcing material 30 in a state where the projected area in the plan view of the lowermost portion is larger than the projected area in the plan view of the uppermost portion. Will be done. In the case of the method shown in FIG. 2 described above, since the recess 20 is drilled after the reinforcing portion 3 is formed, the reinforcing material 30 impregnated in the recess 20 is wasted, but in the case of this method, the surface layer 21 is used. Since all the reinforcing materials 30 to be impregnated in the recess 20 are impregnated so as to go around the recesses 20, the reinforcing material 30 can be used without waste.

Further, since the fixing material 10 is filled in the recess 20 and solidified before the reinforcing portion 3 is formed, the fixing member 10 fixes the buried member 1 in the recess 20 and forms the surface layer 21 around the recess 20. A part of it is impregnated and is firmly integrated with the surface layer 21. Moreover, since the reinforcing portion 3 impregnated with the reinforcing material 30 and solidified is formed in the peripheral portion of the surface layer 21 impregnated with a part of the fixing material 10 in this way, the buried member 1 is reinforced with the fixing material 10. It can be firmly integrated with the portion 3 to exert an anchor effect. Further, since the fixing material 10 is impregnated not only with the recess 20 but also with a part of the surface layer 21 during solidification, even if the fixing material 10 is filled in the recess 20 so as to be flush with the surface layer 21, after solidification. The surface becomes lower than the surface layer 21, but the reinforcing material 30 impregnated in the surface layer 21 so as to circulate around the recess 20 in the subsequent process flows into the surface of the lowered fixing material 10 to form the reinforcing portion. It will be solidified as 3.

Here, after the surface of the fixing material 10 has become lower than the surface layer 21, the reinforcing member 30 is formed by flowing and solidifying the reinforcing material 30 into the lowered portion so as to be flush with the surface layer 21. Although finished, the surface of the fixing material 10 may be provided flush with the upper surface of the surface layer 21 so that the surface of the fixing material 10 is not lower than the surface layer 21. For example, before filling the fixing material 10, a primer or an adhesive or the like is applied to the inner peripheral surface or the bottom surface of the recess 20 to solidify it, thereby preventing the fixing material 10 from penetrating into the surface layer 21 of the fixing material 10. It may be such that the surface of the surface is not lower than the surface layer 21. In this case, the member that suppresses the penetration of the fixing material 10 is not limited to the liquid such as the primer and the adhesive as described above, but the fixing material is obtained by inserting a tubular body such as a metal pipe or a resin pipe into the recess 20. Permeation of 10 may be suppressed.

Further, in the embodiment shown in FIG. 3, since the reinforcing portion 3 is formed after the buried member 1 is installed, the reinforcing portion 3 is provided in the same manner as described above for the installed existing buried member 1. Extraction can be effectively suppressed.

FIG. 4 shows yet another installation method of the buried member 1.
As shown in FIG. 4B, first, the recess 20 is drilled from above the surface layer 21 of the portion where the buried member 1 is to be provided. At this time, the recess 20 is drilled to a depth extending to the middle of the base layer 22 below the surface layer 21, that is, a depth formed so as to be below the upper surface of the base layer 22.

Then, as shown in FIG. 4C, the reinforcing material 30 is poured from above the surface layer 21 so as to orbit around the recess 20, and the surface layer 21 is impregnated with the reinforcing material 30 to be solidified and reinforced. Part 3 is formed. Also in this case, the reinforcing material 30 is used in which the viscosity is adjusted by adding a filler to the reinforcing material 30 according to the degree of impregnation of the surface layer 21. As a result, the mixed layer of the surface layer 21 and the reinforcing material 30 is solidified in a state where the projected area in the plan view of the lowermost end portion is larger than the projected area in the plan view of the uppermost portion, as in the above-described embodiment. The reinforcing portion 3 can be formed. Moreover, a part of the reinforcing material 30 also flows into the recess 20 recessed in the base layer 22 and solidifies, so that it is firmly integrated with the base layer 22.

Then, as shown in FIG. 4D, after the buried member 1 is provided in the recess 20, the gap between the recess 20 is filled with a fixing material 10 such as mortar or an adhesive to solidify the recess 20. As a result, the buried member 1 is fixed in the recess 20.

At this time, since the recess 20 is formed with a reinforcing portion 3 formed by pouring a reinforcing material 30 from above the surface layer 21 so as to go around the periphery and impregnating the recess 20 to solidify the recess 20, the buried member 1 is fixed in the recess 20. At that time, the fixing material 10 filled in the recess 20 is filled in the recess 20 without spreading to the periphery, and is firmly integrated with the reinforcing portion 3. Moreover, the reinforcing portion 3 solidifies in a shape that spreads radially on the surface of the base layer 22 below the surface layer 21, and flows into the recess 20 of the base layer 22 to solidify, so that an excellent anchor effect is exhibited.

Further, since the fixing material 10 filled in the recess 20 is solidified in the recess 20 without spreading to the surroundings, the liquid level of the fixing material 10 filled during curing does not drop, and once. The buried member 1 can be fixed in the recess 20 by the filling operation of.

In each of the above-described embodiments, the lower end of the buried member 1 is located above the upper surface of the base layer 22, but the lower end of the buried member 1 is located below the upper surface of the base layer 22. You may.

Further, in each of the above-described embodiments, the buried member 1 may be a buried member 1 such as an anchor bolt whose upper end is configured to project upward from the surface layer 21.

Further, in each of the above-described embodiments, the buried member 1 is fixed by the fixing material 10 filled in the recess 20, but the method is not limited thereto. For example, even in the installation structure of the buried member 1 such as an anchor bolt, which is installed by expanding the portion of the buried member 1 inserted into the recess 20 and firmly contacting the inner peripheral surface of the recess 20. With the configuration of the present invention in which the reinforcing portion 3 is provided around the 20th portion, the removal thereof can be effectively suppressed.

The present invention can be practiced in various other ways without departing from its spirit or key features.
