Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for creating a running path for vehicles running on a lawn such as a golf course.

[Prior art]

Recently, transport vehicles have been used at golf courses to transport luggage such as golf bags and personnel such as players and players, and the portions where these transport vehicles travel relatively frequently are designated travel routes. Conventionally, when constructing this driving path, asphalt, concrete, or the like is paved along the driving line. However, in this conventional method, the paved road is relatively wide, exceeding the vehicle width of the transport vehicle, resulting in a problem that the appearance of the lawn area becomes poor. On the other hand, in order to prevent this scenery from becoming as bad as possible, it is possible to set up the above-mentioned drive at a location relatively far from the fairway, but if this is done, it will take time to change the clubs used, making it difficult to play. Problems arise in that progress is delayed or play is hindered.

Therefore, as a method of creating a driving path that can solve the above-mentioned problems of deterioration of the scenery and delay in play progress, there is a method described in Japanese Patent Application Laid-Open No. 59-27002, which is a method for creating a driving path. A trench slightly wider than the transport vehicle is excavated along the road, a roadbed is constructed on this roadbed, a concrete foundation is placed along the wheel trajectory on the roadbed, and a concrete rail unit is connected and fixed on the foundation with mortar. However, after that, the grooves around the rails were backfilled.

With the conventional method described in this publication, problems such as deterioration of the landscape of lawn areas can be reduced. However, as mentioned above, during construction, it is necessary to excavate a trench with approximately the same width as the transport vehicle, so this conventional method inevitably damages the running path and a relatively wide area of lawn in the vicinity during construction. Another problem is that it requires a great deal of effort and expense during construction.

[Purpose of the invention]

The present invention was made in view of the problems of the conventional method described above, and it is possible to minimize damage to the lawn during construction, and it is very easy to connect track materials and sleeper timbers, reducing construction time and To provide a method for creating a running road for lawn vehicles that requires very little construction cost.

[Structure of the invention]

The present invention provides a method for constructing a running path for a vehicle along a predetermined running line on a grass ground, in which a lawn on a track portion through which the wheels of the vehicle pass along the running line in a width approximately equal to the width of the wheel. The roots of the lawn are cut so that cuts in the grass in a direction perpendicular to the running line are made at predetermined intervals along the running line and straddle each track section, and then the roots of the lawn are cut at the cuts in the lawn. Then, a flat sleeper with a connecting hole in a predetermined part and a cutter-shaped lower end is driven and buried, and then a track material with connecting holes in both ends is inserted between adjacent ones to form a connecting hole. A connector is placed between the sleepers so that the positions coincide with each other, and a connector having a locking portion at its tip that is larger than the diameter of the connecting hole and having a slit in the center of the locking portion is press-inserted into both the connecting holes. The sleeper timbers and track materials are connected to each other, which minimizes damage to the lawn during construction, and also facilitates work such as forming excavation grooves along the running path and constructing the roadbed. This makes it possible to easily and securely connect sleepers and track materials, and to greatly reduce construction time and construction costs.

The buried portions 8b and 9b, which are the vertical sides of the track members 8 and 9, serve as reinforcing portions to prevent deformation of the mounting portion 9a, and the lower ends of the buried portions 8b and 9b are provided with cutting edges. It is formed into a shape.

Next, the driving machine 4, the sleeper material 7, the track material 8,
The method of this embodiment will be explained using No. 9. No. 7 showing the golf course where the driving path was created by the method of this example.
In the figure, 11 is the fairway, 12 is the teeing ground, 13 is the green, 14 is the bunker, 1
5 is a managed road around the course, 16 is rough,
A travel path 17 is created within the fairway 11 so as to traverse the fairway 11 longitudinally.

The working steps of the method of this embodiment will be explained with reference to FIGS. 1 to 6. (1) First, a running line is set, and along the line, the lawn 11 corresponding to the trajectory of the fairway 11 is moved.
Part a, that is, the raceway materials 8 and 9 for the rear wheels and front wheels.
Peel off a lawn part with approximately the same width as the wheel rest parts 8a and 9a, and further plow the soil in the peeled off part with approximately the same thickness as the wheel rest parts 8a and 9a to create rear and front wheel tracks. Stripes 17a and 17b are formed (see FIGS. 2a and 2b).

(2) Next, position the driving machine 4 so that the rear wheel and front wheel track positioning parts 2 and 3 are located on the rear and front wheel track traces 17a and 17b, respectively (Fig. ), in this state, each of the positioning parts 2 and 3 is aligned with the track line parts 17a and 17.
Drive the driving tool 4 into the soil until it touches the bottom of the plate (Fig. 2 d, Fig. 3 b), and then excavate the soil between the strip-shaped rigid plates 2a and 3a of each of the positioning parts 2 and 3. (Fig. 1 e), and then the driving machine 4 is removed (Fig. 1 f, Fig. 2 c). Then, the rear wheel and front wheel track traces 17a, 17
Rear wheel and front wheel raceway grooves 18a, 18b are formed in b, and sleeper grooves 19 are recessed in a direction perpendicular to these grooves 17a, 17b, and the grass in these grooves 18a, 18b, 19 is recessed. This means that the roots have been severed. Further, using the driving machine 4, the raceway grooves 18a, 18 are
b. Following the sleeper grooves 19, these grooves are sequentially formed along the traveling line.

(3) Then, insert the embedded portion 7d of the sleeper 7 into the sleeper groove 19 so that the upper surface of the connecting seats 7a, 7b is closer to the wheel mounting portion 8 of the track material 8, 9 than the lawn 11a surface.
Drive the sleeper timber 7 into the soil so that it is slightly lower than the thickness of the track materials 8 and 9a (g in the same figure), and in this state insert the buried portions 8b and 8b of the track materials 8 and 9 into their connecting holes 8d and 9e. are inserted into the raceway grooves 18a, 18b so that they are aligned with the connecting holes 7c of the sleeper 7, and the lower surfaces of the wheel rests 8a, 9a are aligned with the connecting seats 7a, 7.
The track members 8, 9 are driven into the soil so as to contact the upper surface of b, and then the track members 8, 9 are connected to the connecting seats 7a, 7b of the sleeper 7 by the connectors 10. The protrusions 8c and 9c of No. 9 will be exposed from the surface of the lawn 11a.

(4) To explain the above connection work in more detail, first align the connection holes 7c of the sleeper 7 with the connection holes 8d and 9e of the track members 8 and 9, and in this state, Align the lower end of the connector 10 with the connector 10 and press the connector 10. Then, the locking portion 10c of the connector 10 is pressed inward and its diameter becomes smaller, and the locking portion 10 passes from the lower surface of the connecting seats 7a, 7b through the connecting holes 8d, 7c or 9e, 7c.
When the base of c protrudes, the locking portion 10c now expands to its original diameter, thereby causing the locking portion 10c to expand to its original diameter.
The base of the sleeper 7 is engaged with the lower surface of the connecting seats 7a and 7b of the sleeper 7 (FIG. 1).

(5) Finally, if the peeled grass is vegetated on the track members 8 and 9, the projections 8 of the track members 8 and 9
c, 9c are exposed from the lawn (Fig. 2h), and in this way a running path 17 is formed along the running line.

In this way, in this example, only the grass that has approximately the same shape as the wheel mounting portions 8a, 9a of the track materials 8, 9 is removed, so damage to the grass during construction can be minimized. In addition, the track materials 8, 9 and sleeper timbers 7 are driven into the soil, and the oval-shaped connecting holes 7c, 8d of the sleeper timbers 7 and track materials 8, 9,
Since the connector 10 is press-inserted into the connector 9e, it is easy to install and connect the track members 8 and 9, which greatly reduces construction time and costs. When thermal expansion occurs, the amount of expansion is measured through the connecting holes 7c, 8d, and 9e.
It can be absorbed by Furthermore, after construction, the only protruding objects from the lawn are the protrusions 8c and 9c, which are hardly visible to the players and therefore hardly spoil the landscape of the lawn.

In the above embodiment, the lawn root cutting work was performed after the lawn peeling work, but this work may be performed in the reverse order, and in the above embodiment, the track material is removed after the sleeper timbers 7 are driven. 8 and 9 are driven in and then the two are connected, but in the present invention, the sleeper timbers 7 and the track materials 8,
It is also possible to connect the parts 9 and 9 with a connector 10, and then drive the connecting units at the same time. Further, in the above embodiment, the sleeper timbers and track materials were installed by driving, but in the present invention, grooves corresponding to the shapes of the sleeper timbers and track materials are formed,
It is also possible to embed sleepers and track materials in the groove.

Further, in the above embodiment, the case of a vehicle having a double tire type front wheel has been described, but the present invention can of course be applied to a traveling road for a vehicle having a single tire type front wheel, and in this case, the front wheel track material is Just make it a little wider than the front wheel of a single-tire type. Furthermore, the present invention can also be applied to a running track for a four-wheeled vehicle that has four running trajectories, in which case two track materials each for the front wheels and two rear wheels are provided,
Further, the guiding material groove may be recessed in the center of each sleeper.

〔Effect of the invention〕

As described above, according to the method for creating a running path for a lawn vehicle according to the present invention, the grass on the track portion through which the wheels of the running vehicle pass is peeled off along the running line with a width approximately equal to the width of the wheel; The roots of the lawn are cut so that cuts in the lawn in a direction perpendicular to the running line enter at predetermined intervals along the running line and straddle each track section, and then cut the roots of the lawn at predetermined intervals along the running line. A flat sleeper with a connecting hole and a cutter-shaped lower end is driven and buried, and then track members with connecting holes at both ends are installed so that the positions of the connecting holes match between adjacent pieces. A connector having a locking part larger than the diameter of the connecting hole at the tip and a slit in the center of the locking part is press-inserted into both the connecting holes to connect the sleeper and the track. Since the materials are connected to each other, damage to the lawn during construction can be minimized, and there is no need to form excavation grooves or construct roadbeds along the running path.
The connection between the sleeper timber and the track material becomes easy and reliable.
This has the effect of greatly reducing construction time and construction cost.
