Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pavement road having a surface layer made of asphalt or the like laid on a road foundation surface made of concrete or the like to repair a floating phenomenon in which the surface layer is separated from the road foundation surface. The present invention relates to a layer repairing method, a surface layer repairing system for a pavement road, and a fluid injection pump with a counter used therein.

[0002]

2. Description of the Related Art For example, pavement of a highway is usually performed by forming a road base surface with concrete and then covering it with a water absorbing type asphalt layer. When such a road surface is used for a long period of time, a floating phenomenon occurs in which the surface layer is separated from the road base surface. If you leave the surface layer with this floating phenomenon, it will roll up when the car is running,
This could cause a serious accident in the following vehicle.

[0003] Therefore, the road manager arranges inspectors in the width direction of the lane, moves the lane along the lane while hitting the road surface with a hammer, and when a floating phenomenon is discovered, uses chalk or the like at the place. Marked. Then, a plug for injecting a high-pressure fluid as shown in FIG. 10 is inserted into a fluid-injection hole 36 formed in a road surface, and an adhesive such as an acrylic resin that does not leak environmental hormones or the like is injected into the high-pressure fluid infusion. High pressure injection was performed using a pump. The plug 100 for high-pressure fluid injection shown in FIG.
12, a male screw member 114, and a cylindrical rubber packing material 116.

[0004] The nipple member 112 is connected to the nipple head 11.
A nipple main body 112b having a hexagonal nut portion engaging with a rotating means such as 2a and a spanner is integrally formed. The outer shape of the nipple head 112a is adapted to be liquid-tightly connected to a device for injecting a high-pressure fluid, for example, an injection coupling or a chuck nozzle of a high-pressure pump.

The male screw member 114 is formed integrally with a large diameter check valve portion 114c having a check valve formed therein and a stem portion 114a having a male screw 114b cut on the outer peripheral surface. Things. As described above, the nipple member 1
12 female screw 112e is the male screw 1 of the stem 114a.
14b. At the center of the male screw member 114, a center hole 114d penetrating in the longitudinal direction is formed.

In the illustrated example, the check valve is a check valve part 1.
The center hole 114d is bored in the longitudinal direction inside 14c.
A leaf valve comprising a ball storage portion 114e having a larger inner diameter, a ball 114f stored in the ball storage portion 114e, and a leaf plate 114g for pressing the ball 114f against a center hole 114d with a predetermined force. ing. The leaf plate 114g which is thin in the longitudinal direction presses the ball 114f against the center hole 114d with a predetermined force. The packing material 116 is a cylindrical rubber packing material.

The above-described conventional plug 10 for injecting high-pressure fluid
The injection operation using 0 is performed as follows. A fluid injection hole 36 having a diameter slightly larger than the outer diameter of the high-pressure fluid injection plug 100 is formed in a repair target, for example, a road surface of a highway. The fluid injection hole 36 is provided in the surface layer 34.
It is necessary to have a depth to reach the gap 37 formed between the concrete part 35 and the concrete part 35. The high-pressure fluid injection plug 100 is inserted into the fluid injection hole 36 (see FIG. 5A), and the nipple member 12 is rotated in the direction of arrow X by a rotating means such as a spanner. Male screw member 11
4 male screw 11 of check valve part 114c and stem part 114a
The packing material 116 sandwiched between the end face of the nipple member 112 screwed to 4b is compressed and contracted in the longitudinal direction and expanded in the circumferential direction to be tightly fixed to the fluid injection hole 36. Thereafter, an injection coupling (not shown) of a device used for injecting a fluid is attached to the nipple head 112a, and an adhesive such as an acrylic resin is injected (see FIG. 5B).

Immediately after the completion of the injection of the adhesive, the nipple member 112 is rotated in the direction opposite to the arrow X by rotating means such as a spanner. As a result, the packing material 116 returns from the state of being compressed and contracted in the longitudinal direction and expanded in the circumferential direction to the original cylindrical state, and can freely move in the fluid injection hole 36. Then, the high-pressure fluid injection plug 100 is pulled out from the fluid injection hole 36, and if necessary, the joint material 38 is filled in the fluid injection hole 36 to complete the operation.

[0009]

In the conventional plug 100 for injecting high-pressure fluid described above, the plug 10 for injecting high-pressure fluid is used.
0 is inserted into the fluid injection hole 36 to inject the fluid,
It is necessary to rotate the portion of the nipple body 112b with a hexagon wrench or the like to expand the rubber packing material 116 and tightly fix it in the fluid injection hole 36. In addition, after the injection, the rubber packing material 116 is opened from the inner surface of the fluid injection hole 36, and when the high-pressure fluid injection plug 100 is pulled out, it is necessary to rotate the nipple body 112b with a hexagon wrench or the like. Therefore, the trouble of rotating the nipple member 112 a predetermined number of times is not ridiculous when the number of the nipple member 112 is several hundreds or thousands, and it is an extremely complicated and time-consuming operation.

In the conventional method, after the fluid is injected, the nipple member 112 is rotated in a direction opposite to the arrow X by a rotating means such as a wrench to return the packing material 116 to its original cylindrical shape, and High pressure fluid injection plug 100 from 36
I was pulling out everything. However, the fluid injection hole 3
If the repair fluid in 6 has a residual pressure, there is a possibility that the repair fluid such as an adhesive blows out in a spray state. When an acrylic resin is used as an adhesive, the risk of skin damage is reduced as compared with an epoxy resin, but the adhesive is dangerous when entering the eyes and may damage the eyeball. Also, the amount of adhesive actually injected into each gap,
The number of injections into the same site, etc., was not originally measured, and there was no record at all. Therefore, when to replace the next surface layer depends on the visual inspection and experience of the inspector at the site, and the momentum and the timing will be set earlier, causing the rise in maintenance costs. Had become.

Accordingly, an object of the present invention is to provide a method for repairing a surface layer of a pavement road and a system for repairing a surface layer of a pavement road for repairing a floating phenomenon in which a surface layer is separated from a road foundation surface in a short time and surely. And Another object of the present invention is to provide a method for repairing a surface layer of a paved road and a system for repairing a surface layer of a paved road that repair a floating phenomenon in which a surface layer is peeled off from a road foundation surface systematically and automatically without relying on humans. With the goal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for repairing a surface layer of a pavement for fluid injection, a system for repairing a surface layer of a pavement road, and a fluid injection pump with a counter used therein according to the present invention will be described based on the illustrated embodiments. This will be described in more detail. FIG. 1 is a perspective view of an embodiment in which a surface layer repair system for a pavement road according to the present invention is constructed as a drag-type automatic repair vehicle. FIG. 2 is a cross-sectional view of a main part of the pavement road surface layer repair system shown in FIG.

The illustrated self-repair vehicle 10 is connected to the rear of another towing vehicle and is dragged, but of course, it can be a self-propelled vehicle as a dedicated vehicle. The automatic repair vehicle 10 has a frame structure,
The four tires can move on the road surface. A first platform 14 that supports the drilling device 12 and a second platform 20 that supports the high-pressure fluid injection device 16 and the joint filling device 18 are arranged inside the automatic repair vehicle 10. First platform 14
Is attached to the automatic repair vehicle 10 so as to be able to reciprocate in the traveling direction and the vertical direction of the automatic repair vehicle 10. The position can be precisely controlled using a conventionally known linear guide device and a ball screw mechanism. Platform 20
May be fixed to the automatic repair vehicle 10 or may be attached so as to be able to reciprocate in the traveling direction and / or the vertical direction of the automatic repair vehicle 10.

In the preferred embodiment shown, three drilling devices 12 are mounted on the first platform 14, but are arbitrarily modified by the number of fluid injection holes 36 to be formed per predetermined area. Normally, a floating phenomenon in which a surface layer is separated from a road foundation surface occurs intensively at a rut portion of a pavement road. Therefore, it is preferable to provide these devices in a number that can include both of the two ruts in at least one lane. By using a plurality of devices, repair of the one lane can be completed at once.

Further, means for adjusting the lateral spacing, for example, the mounting hole for the first platform 14 may be an elongated hole 14a long in the width direction of the automatic repair vehicle 10. It is preferable that the drill device 12 is driven by an air motor that does not cause a fire due to a spark. Compressor 24
Thus, compressed air is formed, and the compressed air is supplied to each drill device 12 using the pipe 26 having flexibility on the way. Platform 2 of the first platform 14
The fork member 22 that can be inserted into the fluid injection hole 36 that is already drilled is attached to the side surface on the 0 side so as to be able to reciprocate in the vertical direction. The fork member 22 is moved up and down at a predetermined timing by a conventionally known ball screw mechanism (not shown) and a control device for controlling the same.

A predetermined number of high-pressure fluid injection devices 16 and joint material filling devices 18 are also provided on the platform 20. In the surface layer repair system for paved roads,
A buried plug for fluid injection is used so that safety and automation of work can be achieved. FIG. 3 is a cross-sectional view showing one embodiment of such an embedded fluid injection plug. As shown in FIGS. 3A and 3B, the self-tightening plug 1
Is schematically an inner member 3 made of a high-grade plastic such as Delrin resin, and an elastic material slidably mounted on the outer periphery of the inner member 3 so as to be slidable in the axial direction of the inner member 3, for example, The outer sleeve 5 made of NBR rubber is composed of only two members. Inside member 3
Is provided with a central hole 3a in the axial direction and a horizontal hole 3b in the radial direction that is fluidly connected near the tip end thereof. On the opening side of the central hole 3a, a female screw 3c for attaching the nozzle 7 for injecting the high-pressure fluid in a liquid-tight manner is formed. The outer peripheral surface of the inner member 3 is provided with a conical surface 3d having an inverse taper toward the opening of the central hole 3a.

On the other hand, the outer sleeve 5 is manufactured by injection molding so as to have a valve portion 5a for opening and closing the lateral hole 3b of the inner member 3 and a cylindrical portion 5b following the valve portion. The inner peripheral surface of the cylindrical portion 5 b is a conical inner surface 5 c having a shape that complements the inverted tapered conical surface 3 d of the inner member 3. In the illustrated preferred embodiment, the outer peripheral surface of the cylindrical portion 5b of the outer sleeve 5 is provided with a plurality of axial projections 5d extending in the axial direction and a plurality of ring projections 5e extending in the circumferential direction. ing. Contact with the fluid injection hole 36 creates a frictional force, thereby preventing the outer sleeve 5 from slipping against the fluid injection hole 36.

As a material of the inner member 3 and the outer sleeve 5, the frictional force between the outer sleeve 5 and the inner member 3 is larger than the frictional force between the fluid injection hole 36 of the structure and the outer sleeve 5. Is selected to be smaller by a predetermined ratio.
The angle of the inverted tapered conical surface 3d of the inner member 3 and the conical inner surface 5c of the outer sleeve 5 having a shape complementary thereto with respect to the axis is 3 to 10 °. When the inner member 3 is made of Delrin resin and the outer sleeve 5 is made of NBR rubber, only a slight contact between the outer sleeve 5 and the fluid injection hole 36 is obtained within this range, and the friction is caused by the friction. Since the frictional force between the outer sleeve 5 and the inner member 3 is smaller than the force, the inner member 3 slides outward with respect to the outer sleeve 5 in the axial direction. Thereby, the outer sleeve 5 is connected to the inner member 3.
3d pushes and expands outward in the circumferential direction to tightly fix the outer sleeve 5 and the inner surface of the fluid injection hole 36 (see FIG. 3B). Of course, it should be understood that this angle will vary depending on the material used.

The valve portion 5a of the outer sleeve 5 is provided so as to surround the portion where the horizontal hole 3b of the inner member 3 is located, and can seal the periphery of the horizontal hole 3b with a wide area. Therefore, there is no problem in performance at all even when used at a high pressure such as 40 MPa or more. Further, the inner member 3
And the valve portion 5a of the outer sleeve 5 can be easily sealed by surface contact and have a central hole 3a of the inner member 3.
In addition, since there is no member to be caught in the lateral hole 3b, even when a filler such as a reinforcing fiber is contained, it can be almost completely sealed.

FIGS. 4 and 5 differ from FIG. 3 in that a valve member 9 having elasticity for opening and closing the lateral hole 3b of the inner member 3 is provided instead of the valve portion 5a. Different from the ones.

The number of the lateral holes 3b of the inner member 3 may be one or more. A rectangular groove (FIG. 4) or a circular groove (3 e) into which an O-ring 9 having a circular cross section (FIG. 5) is fitted on the outer periphery including the position where the horizontal hole 3 b is formed in the inner member 3. A groove 3f is formed. Central hole 3a and side hole 3 at high pressure
The fluid discharged through b opens the O-ring 9 to form a flow path, and then is discharged to the fluid injection hole 36.

The O-ring 9 has grooves 3d, 3f formed on the outer periphery including the position where the lateral hole 3b of the inner member 3 is formed.
And is in surface contact with the contact surface. Thereby, the sealing between the inner member 3 and the O-ring 9 can be performed almost completely despite its simple structure. In addition, since sealing is performed not with a line but with a surface, the sealing can be relatively completely performed even when a filler such as a reinforcing fiber is contained in the fluid. The O-ring 9 is made of rubber or metal and elastically expands. In the case of metal, a cut is required like a piston ring, but the cut is arranged so as to deviate from the position of the lateral hole 3b formed in the inner member 3. O-ring 9
When made of rubber, it has a continuous ring shape, but when made of metal, it needs to extend over a central angle of 180 degrees or more and less than 360 degrees. Thereby, the O-ring 9 is fitted without falling into the grooves 3e and 3f of the inner member 3.

Each of the valve members 9 has a simple and simple structure and can reliably close and open the lateral hole 3b of the inner member 3 in an openable and closable manner. Because of the simple structure, the outer diameter of the entire automatic fastening plug 1 can be reduced (downsized). Since the elastic modulus or strength of the valve member 9 can be changed in any way, a malfunction does not occur even with a high-pressure fluid of 40 MPa or more.

FIGS. 6 (a) and 6 (b) are cross-sectional views of still another embodiment of a self-clamping plug for fluid injection.
Shows the state before fluid injection and the state after injection. In the illustrated preferred embodiment, two or more axially formed inverted tapered conical surfaces 3d of the inner member 3 and the conical inner surface 5c of the outer sleeve 5 of a complementary shape. At a plurality of points in the axial direction, the inner member 3 expands the outer sleeve 5 in the circumferential direction outward, and tightly fixes the outer sleeve 5 and the inner surface of the fluid injection hole 36. Thus, there is an effect that the possibility that the fluid is ejected to the outside of the fluid injection hole 36 can be reduced to the utmost.

The buried type fluid injection plug is not limited to the one described above, and any plug may be used as long as the fluid injection plug including the portion having the check valve mechanism in the fluid injection hole is left tightly fixed. It may be something like this. For example, a tappable high-pressure fluid injection plug and the like described in JP-A-11-62260 can be used.

In the preferred embodiment shown, the high-pressure fluid injection device 16 has a nozzle 7 that is threadedly connected to the self-tightening plug 1 for fluid injection shown in FIGS. Therefore, the tip of the nozzle 7 is provided with the automatic tightening type plug 1
A male screw 7a screwed with the female screw 3c formed on the inner member 3 is formed. The high-pressure fluid injection device 16 is provided with a hand device 28 adjacent to the high-pressure fluid injection device 16. Supply just below.
The linear guide device 30 with a ball screw mechanism, which supports the nozzle 7 in the high-pressure fluid injection device 16 so as to be movable in the vertical direction, drives the linear guide device 30 with the ball screw mechanism so that the lower end of the nozzle 7 has Make contact. As a drive source of the ball screw mechanism, it is preferable to use an air motor that does not generate sparks. Activate the rotation drive mechanism not shown,
The nozzle 7 is rotated in the tightening direction to securely fasten the automatic tightening type plug 1 and the nozzle 7. Thereafter, the finger of the hand device 28 is opened, and the nozzle 7 is further lowered,
It is inserted into the hole 36 for fluid injection. In the preferred embodiment shown, a fork member 32 similar to the fork member 22 is provided below the platform 20 and is inserted into a fluid injection hole 36 drilled by the drilling device 12.

In order to reliably position the nozzle 7 and the fluid injection hole 36, it is preferable to provide the fork members 32 extending in two rows in the traveling direction of the automatic repair vehicle 10. The lowering of the fork member 32 corresponds to the platform 2
0 itself may be moved up and down, or the fork member 32 may be moved up and down independently. Due to the existence of such a positioning mechanism,
The nozzle 7 having the automatic tightening type plug 1 screwed to the tip can be reliably guided into the fluid injection hole 36. With the automatic tightening type plug 1 tightly fixed to the inner wall of the fluid injecting hole 36, high-pressure fluid is injected into the fluid injecting hole 36 from the high pressure fluid injecting device 16 through the nozzle 7 and the automatic tightening type plug 1. inject.

As soon as the injection is completed, the nozzle 7 is rotated in the loosening direction. Since the automatic tightening type plug 1 is tightly fixed to the inner wall of the fluid injection hole 36, the female screw 7a of the nozzle 7 is disengaged from the female screw 3c of the central hole 3a. next,
By driving the linear guide device 30 with the ball screw mechanism, the nozzle 7 is returned to the initial position, and the entire platform 20 is moved by one pitch in the traveling direction of the automatic repair vehicle 10,
The joint material 38 is injected from the joint material filling device 18. For example, the fork member 22 is moved down to
Insert Then, the automatic repair vehicle 1 (not shown)
With the moving mechanism between the zero and the first platform 14 opened, the entire automatic repair vehicle 10 is pulled toward the towing vehicle by one pitch. This makes it possible to accurately position the discharge port of the nozzle 7 and the joint filling device 18 with the fluid injection hole 36.

Of course, the hole 3 for fluid injection using a sensor
Various positioning methods such as a method of accurately determining the position of No. 6 and matching the discharge port of the nozzle 7 and the joint filling device 18 can be adopted. In addition, a small roller 33 is provided behind the joint filler 18 so that the joint 38 can be leveled. Thus, a road surface that does not hinder the running of the vehicle can be provided.

As described above, the system for repairing a surface layer of a pavement road according to the present invention pierces a predetermined number of fluid injection holes per predetermined area regardless of whether or not the surface layer has peeled off. Therefore, even on a road surface in a state where the surface layer has not been separated from the road base surface, fluid injection holes are drilled at a predetermined ratio,
A repair fluid such as an adhesive is injected at a high pressure. When the repair work is repeatedly performed on the same road surface, the position of the fluid injection hole can be shifted intentionally with reference to the white line dividing the lane. Thereby, the peeling phenomenon can be made more difficult to occur.

Although not shown, it is possible to provide a pavement surface hitting device for hitting the pavement surface and detecting the floating phenomenon of the surface layer by the echo. In this case, the high-pressure fluid injection device 1
6 controls so as to inject a large amount of high-pressure fluid into a site found by the pavement hitting device. In such an embodiment, the high-pressure fluid injection device 16 automatically stops the fluid supply when the amount of the supplied high-pressure fluid reaches a predetermined amount for each of the fluid injection holes 36, and the restart signal by the field worker is provided. , The supply can be controlled to be restarted. The amount of the repair fluid supplied to each of the fluid injection holes 36 can be measured and recorded in a memory of a computer (not shown). Further, the total amount of the repair fluid injected into the whole or the predetermined area can be measured and recorded separately from the individual one.

As described above, when measuring and managing the injected repair fluid, it is desirable to use a pump of a type that can easily measure the amount of the injected repair fluid. It is preferable that the high-pressure fluid injection device 16 use a reciprocating displacement pump, for example, a diaphragm pump, which can measure the fluid supply amount by counting the number of reciprocating movements. A spool for controlling the movement of the diaphragm is projected outward from the pump body, and the number of reciprocations of the diaphragm can be counted by detecting the movement of the projection electrically or mechanically using a limit switch or the like. .

On the other hand, by detecting a change in the pressure of the repair fluid injected into each fluid injection hole 36, control is performed so that the fluid supply is automatically stopped when the supplied high-pressure fluid reaches a predetermined pressure. You can also. The stopped high-pressure fluid injection device 16 can be controlled so as to restart supply by transmitting a restart signal by a field worker.

Next, a method of operating the pavement road surface layer repair system according to the present invention in the form of the above-described automatic repair vehicle 10 will be described. In the system of the present invention,
The automatic fastening type plug 1 shown in FIGS. 3 to 6 is used. The self-repair vehicle 10 according to the present invention is connected to the towing vehicle, and moves to a place where a road requiring repair is present. For example,
The two-component acrylic resin is stored in a required amount in the tank 11. In addition, a large amount of the automatic tightening type plug 1 is supplied to an automatic tightening type plug supply device (not shown). These consumable materials and components are replenished as needed.

In the first stage of the operation, the fork member 32
Platform 2 so that the tip of the
The 0 and / or fork member 32 is lifted to a raised position by driving the up-down mechanism. Similarly, the tip of the fork member 22 is lifted to a raised position so as not to contact the road surface. In addition, the first platform 14 is arranged behind the automatic repair vehicle 10 by at least one pitch (the interval between the fluid injection holes 36 in the lane longitudinal direction).

After confirming that the automatic repair vehicle 10 is oriented in the longitudinal direction of the lane by using a sensor (not shown), the first platform 14 is lowered, and a plurality of drilling devices 12 are used to simultaneously form the lane. A plurality of fluid injection holes 36 are formed in a line in the width direction. After drilling to the depth reaching the gap 37 generated between the surface layer 34 and the concrete 35, that is, at least the depth reaching the concrete portion 35, the hole is returned to the initial ascent position. next,
The first platform 14 is connected to the automatic repair vehicle 10 using a linear guide device with a ball screw mechanism (not shown).
Is moved forward by one pitch. Fork member 2
2 is lowered, and the fork member 22 is inserted into the drilled fluid injection hole 36 for positioning. Fork member 2
2 at the same speed while raising the first platform 14 relative to the first platform 14.
Is lowered with respect to the automatic repair vehicle 10. In the same manner as described above, after the plurality of fluid injection holes 36 are formed, the operation of returning to the original ascending position is performed a plurality of times.

In the illustrated preferred embodiment, a total of four
With the fluid injection holes 36 in the row drilled, injection of the repair fluid is started (see FIG. 2). That is, as described above, the fork member 22 is
Then, the plurality of drilling devices 12 are lowered to form a new row of holes 36 for fluid injection. At the same time, the fork member 32 is lowered and inserted into the fluid injection hole 36 in two rows. Since the positioning is performed in two rows, not only the longitudinal pitch can be precisely controlled, but also the rear of the automatic repair vehicle 10 can be prevented from swinging in the width direction of the road.

The hand device 28 holds one automatic tightening type plug 1, holds the automatic tightening type plugs 1 one by one from an automatic supply device (not shown), and supplies the plugs directly below the nozzle 7. I do. The linear guide device 30 with a ball screw mechanism that supports the nozzle 7 is driven to bring the lower end of the nozzle 7 into contact with the opening of the central hole 3 a of the automatic tightening type plug 1. Before or after this, the rotation driving mechanism (not shown) is operated to rotate the nozzle 7 in the tightening direction, and the automatic tightening type plug 1 and the nozzle 7 are securely fastened. After the self-tightening plug 1 and the nozzle 7 are securely fastened, the fingers of the hand device 28 are opened to allow the nozzle 7 to move. Then, the linear guide device 30 with the ball screw mechanism is driven to further lower the nozzle 7 and insert it into the fluid injection hole 36.

In the illustrated preferred embodiment, the automatic tightening type plug 1 is screwed to the tip by providing a positioning mechanism over two rows, that is, a combination of the fork member 32 and the fluid injection hole 36. The nozzle 7 can be reliably guided into the fluid injection hole 36. The automatic tightening type plug 1 shown in FIGS. 3 to 6 is automatically and reliably tightly fixed to the inner wall of the fluid injection hole 36 by injecting the repair fluid, so that the system is completely automated. This is extremely advantageous. In this manner, in a state where the automatic tightening type plug 1 is tightly fixed to the inner wall of the fluid injection hole 36, the high pressure fluid is injected from the high pressure fluid injection device 16 to the pipe 16 a including the flexible portion, the nozzle 7. Then, the fluid is injected into the fluid injection hole 36 via the automatic tightening type plug 1.

As soon as the injection is completed, the nozzle 7 is rotated in the loosening direction. Since the automatic tightening type plug 1 is tightly fixed to the inner wall of the fluid injection hole 36, even if there is a large residual pressure in the repair fluid in the fluid injection hole 36, it will be ejected to the outside. Will not cause. When the nozzle 7 is rotated in the loosening direction, the female screw 7a of the nozzle 7 is rotated.
Comes off from the female screw 3c of the central hole 3a.

Next, the linear guide device 3 with a ball screw mechanism
0 to return the nozzle 7 to the initial position,
The fork member 32 is drawn out of the fluid injection hole 36. On the other hand, the fork member 22 is lowered and inserted into the fluid injection hole 36. The entire platform 20 is moved by one pitch, and the joint filler 38 is injected from the joint filler 18. That is, the entire automatic repair vehicle 10 is pulled toward the towing vehicle by one pitch in a state where the moving mechanism between the automatic repair vehicle 10 and the first platform 14 (not shown) is opened. Thereby, the outlet of the nozzle 7 and the joint filling device 18 and the hole 3 for fluid injection are formed.
6 can be accurately positioned.

Of course, the fluid injection hole 3 using the sensor
Various positioning methods such as a method of accurately determining the position of No. 6 and matching the discharge port of the nozzle 7 and the joint filling device 18 can be adopted. Joint filling device 18
The small rollers 33 disposed behind the joints flatten the joint material 38, and can provide a road surface that does not hinder the running of the vehicle.

As a result, it is possible to suppress or eliminate the occurrence of the floating phenomenon itself in which the surface layer is peeled off from the road base surface, significantly prolong the life of the pavement surface, and eliminate the need for manual work to detect the floating phenomenon. Therefore, road management costs can be reduced, the adverse effects of high-pressure injection (leakage, backflow, waiting time for the adhesive to harden, etc.) are eliminated, and there is no problem with materials containing fibrous reinforcing agents. It has the advantages of all or any of these or any combination thereof, such as being able to be used for delicate injection at a low pressure due to low inflow resistance, and easy to manufacture small diameter ones.

The above-mentioned automatic repair vehicle 10 is constructed as a fully automated model of the pavement road surface layer repair system according to the present invention. Of course, one or more of the components or all The operation of the components can be performed manually.

Next, the method for repairing the surface layer of a pavement according to the present invention will be described in detail. FIG. 9 is a block diagram of an embodiment of a method for repairing a surface layer of a pavement road according to the present invention. The method for repairing a surface layer of a pavement road according to the present invention generally includes a step S1 of forming a predetermined number of fluid injection holes per a predetermined area regardless of the presence or absence of a floating phenomenon,
Step S2 of supplying a repair fluid from a high-pressure fluid supply source using the buried type fluid injecting plug 1 and injecting the high pressure through the fluid injecting hole, and leaving the embedded type fluid injecting plug in the fluid injecting hole. And disconnecting the connection with the high-pressure fluid supply source, loading the joint material into the fluid injection hole, and performing a surface treatment.

The illustrated preferred embodiment further includes the step of measuring the amount of fluid injected into each fluid injection hole and / or the fluid injection hole within a predetermined range and recording it on a recording device S4. I have. The data recorded in this recording device can be used later when repair work is performed on the same road surface. Alternatively, the data is used as basic data for studying the relationship between the use of roads, for example, the degree of influence on the floating phenomenon of tire chains and snow tires in snowfall areas and its repair effect. The relationship when many heavy vehicles such as trucks pass, and the relationship with the simple traffic amount, etc., are valuable basic data on what frequency of repair work should be performed.

As described above, the fluid supply amount can be easily measured by counting the number of reciprocating movements of a reciprocating displacement pump, for example, a diaphragm pump. Fluid supply is provided by providing a control device to automatically stop the supply when the amount reaches a predetermined value for each fluid injection hole, and restart the supply by sending a restart signal by a field worker. Can be configured. For example, prior to the fluid injection hole drilling step S1, a pavement surface is hit and a reverberation is used to find a floating phenomenon of the surface layer in step S5.
In the case of the embodiment shown in the figure, it can be controlled to inject a large amount of high-pressure fluid into the site found by the floating phenomenon finding step. As described above, when the method of the present invention is performed on a pavement road at an appropriate period, the floating phenomenon itself is drastically reduced or eliminated. Therefore, the floating phenomenon discovery step S5 can be a step to be added only in special cases.

Although not shown, fluid supply can also be performed by controlling the pressure determined for each fluid injection hole. When the pressure becomes equal to or higher than a predetermined pressure, the supply of the repair fluid is automatically stopped, and the supply is restarted by transmitting a restart signal from a site worker.

EXAMPLE In a periodic inspection in a tunnel of a highway, an experiment was conducted to demonstrate the difference between the conventional method and the method of the present invention. The purpose of the periodic inspection is to discover floating phenomena on highways beyond winter. A two-component acrylic resin was injected into the found floating phenomenon site, and it was confirmed whether or not the surface layer 34 could be fixed to the concrete portion 35. The cross section in the tunnel is as shown in FIG. 7A, and a concrete section 35 having a thickness of about 500 mm is bridged below the concrete foundation pipe 40 having a circular cross section. On the upper surface, a surface layer 34 made of moisture-permeable asphalt is adhesively fixed at a thickness of 30 to 50 mm. Note that a tile 42 is attached to the inner peripheral surface of the concrete foundation pipe 40.

When the road manager guides the user into the tunnel,
Five inspectors were placed on the traveling lane side of the ascending lane, and each hammer hit a hammer on the road surface to check for floating phenomenon due to the echo. As a result of a percussion inspection of the entire 1.7 km tunnel section, floating phenomena of various sizes were found at an average interval of 2 to 5 m (see FIG. 7B).

At a place where a plurality of floating phenomena occurred, a center portion thereof was determined, and a fluid injection hole 36 reaching the concrete portion 35 was formed in the center portion (13 mm in diameter).
90 mm deep). To this, various adhesives were injected to test the adhesive effect. As a result of the experiment, good results were obtained when a commercially available two-pack acrylic resin was used. The pump is NGN9538 type "Gokutokun (trade name)" made by Nippon Grease Nipple which can inject high pressure (Japan Grease Nipple Co., Ltd .:
7-23, Hinodemachi, Sakado-shi, Saitama). FIG.
(B) The first floating phenomenon site from the top is 50 cm X 5
Since it was 0 cm, 770 mL at a pump pressure of 7 MPa
Injected. The injection was confirmed by visually checking that the injection liquid emerged on the asphalt from the entire floating phenomenon site.

Since the second floating phenomenon site from the top in FIG. 7B was 75 cm × 150 cm, the injection point was 2 cm.
Divided into two places. The pump pressure in the upper fluid injection hole 36 was 12 MPa and 4060 mL was injected. The pump pressure in the lower fluid injection hole 36 is 2800 at 9 MPa.
mL was injected. Since the third floating phenomenon site from the top in FIG. 7B was 85 cm × 85 cm, the pump pressure 8
1008 mL was injected with MPa. 4 from the top of FIG.
The second floating phenomenon site is the same 50cmX50c as the first
m, 1500 mL at a pump pressure of 24 MPa
Injected. Here, a two-component urethane resin of another manufacturer was used for comparison.

In this experiment, the automatic tightening type plug 1 described above was used.
Since the production of the product was not made in time, a plug for fluid injection which was not a buried type was used. Therefore, immediately after the injection of the repair fluid, the screw was loosened, and all the fluid injection plugs were taken out. After a lapse of 4 hours from the injection, the state of the injection and the fixation was inspected, and it was evaluated that "the filling and fixing state was extremely good." The evaluation criteria were that the work was completed in a short time, that all parts where the floating phenomenon had appeared were completely filled, and that it was recognized that they had penetrated into small gaps in the surrounding area. Was.

In addition, due to the nature of the pavement of the road, the conventional metal fluid injection plug used as a substitute for the automatic tightening type plug 1 does not allow the embedding of metals for safe driving of automobiles. It was a judgment. Since the automatic tightening type plug 1 is a type that does not use any metal,
There is no problem. The urethane resin has a disadvantage that the injection pressure is increased because the viscosity at the time of injection is higher than that of the acrylic resin. Also, at a location different from the above-mentioned repair work site, regardless of the presence or absence of a floating phenomenon, the number of fluid injection holes determined per predetermined area, specifically, at 30 cm intervals in the longitudinal direction and width direction of the lane. And the above-described two-part acrylic resin was injected. The pump is also NGN9538 made by Nippon Grease Nipple, which is capable of injecting high pressure as described above.
The model "Kaketo-kun (trade name)" (Japan Grease Nipple Co., Ltd .: 7-23 Hinode-cho, Sakado-shi, Saitama) was used.
The injection was continued at a pump pressure of 30 MPa until the injection pressure reached this value, and the injection was stopped when the fluid pressure reached 30 MPa. The injection amount of each fluid injection hole 3 until the fluid pressure reached 30 MPa was grasped by measuring the number of reciprocating movements of the pump. This was recorded on a paper as a matrix table. The method according to the method of the present invention was also evaluated as “the filling and fixing state is extremely good.” Since no continuous construction experiments have been conducted, the effect on the life of paved roads has not been confirmed.
