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 install the above-mentioned running path relatively far away from the fairway, but if this is done, it will take time to change the clubs being used, and The problem arises that the progress of the game is delayed or that the 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 grass 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 has been made in view of the problems of the conventional method described above, and is a lawn vehicle that can minimize damage to the lawn during construction, and that requires very little construction time and construction cost. The purpose is to provide a method for creating driving routes.

[Structure of the invention]

The present invention is a method for constructing a running path for vehicles along a predetermined running line on a lawn ground, in which sleepers are buried at predetermined intervals along the running line so that cuts in the lawn in a direction perpendicular to the running line are formed. Moreover, this is done by cutting the roots of the lawn so as to straddle each track portion, and driving a flat sleeper whose lower end is shaped like a cutting edge into the cut in the lawn. As a result, the lawn only needs to be removed from the track section where the wheels of vehicles pass, minimizing damage to the lawn when constructing the running track, and also making it easier to form excavated grooves along the running track. This eliminates the need for roadbed construction and roadbed construction, making it possible to significantly reduce construction time and construction costs.

〔Example〕

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

A, 9a have a large number of truncated conical protrusions 8c, 9c protruding over the entire surface, and the wheel mounting portion 9a of the front wheel track material 9 has an induction material groove 9d for installing an induction material. is recessed. The buried portions 8b, 9b, which are the vertical sides of the track members 8, 9, serve as reinforcing portions to prevent deformation of the placement portions 8a, 9a, and the lower ends of the buried portions 8b, 9b are It is shaped like a cutting edge.

In addition, in FIG. 9 showing the front wheel track material 29 of the track block buried at the automatic stop position of the traveling vehicle, the wheel mounting portion 29a of the front wheel track material 29 has a guiding material groove 9a in the traveling direction and a guide material groove 9a orthogonal thereto. A guiding material groove 9e is recessed in the direction in which the guiding material 20 is wound around the guiding material grooves 9d and 9e in a roughly figure 8 shape. A magnetic field is obtained, which can be used to automatically stop the vehicle.

Next, the driving machine 4, the sleeper material 7, the track material 8,
The method of this embodiment will be explained using No. 9 and No. 29. In FIG. 6, which shows a golf course with a driving path created by the method of this embodiment, 11 is a fairway, 12 is a teeing ground, 13 is a green, 14 is a bunker, 15 is a management road around the course, and 16 is a 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 5. (1) First, a running line is set, and along the line the lawn 11 is moved along the trajectory of the fairway 11.
A portion a, that is, a lawn portion 11 having approximately the same width as the wheel mounting portions 8a and 9a of the rear wheel and front wheel track members 8 and 9.
a, and then remove the wheel mounting portions 8a and 9a.
The soil in the peeled off portion is removed with approximately the same thickness as the rear wheel and front wheel track traces 17a and 17b.
(see Figure 1 a, b).

(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. 1d, Fig. 2b), and then remove the soil between the strip-shaped rigid plates 2a and 3a of the positioning parts 2 and 3. After that, the driving machine 4 is removed (FIG. 1 f, FIG. 2 c). Then, the rear wheel and front wheel track traces 17a, 17b
Rear wheel and front wheel raceway grooves 18a and 18b are formed in the grooves, and a sleeper groove 19 is recessed in a direction perpendicular to the raceway grooves 17a and 17b, and the grass roots in this groove 19 portion are cut. becomes. Further, using the driving machine 4, following the raceway grooves 18a, 18b and sleeper grooves 19, these grooves are sequentially formed along the running 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 timbers 7 into the soil so that they are slightly lower than the thickness of the track materials 8 and 9a (g in the same figure).
8a, 18b, wheel rest parts 8a, 9
Drive the track materials 8 and 9 into the soil so that the lower surfaces of the connecting seats 7a and 7b contact the upper surfaces of the connecting seats 7a and 7b,
After that, the track members 8 and 9 are attached to the connecting seat 7 of the sleeper timber 7.
a, 7b by the connector 10, the protrusions 8c, 9c of the track members 8, 9 will protrude slightly above the surface of the lawn 11a.

(4) Furthermore, the sleeper timbers 7 are successively driven into the adjacent sleeper grooves 19, the raceway materials 8 and 9 are driven into the raceway grooves 18a and 18b, these are connected by the connector 10, and finally the said raceway materials 8 and 9 If the peeled grass is planted on top of the grass, the protrusions 8c and 9c of the track materials 8 and 9 will be slightly exposed from the grass (Figures 4 and 5), and in this way, the running line will be A running path 17 is constructed along the road.

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. , track materials 8, 9 and sleeper timbers 7
Since it is driven into the soil, construction time and costs can be greatly reduced. Moreover, after construction, the only things exposed 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 addition, since the connecting holes 7c are long in the track direction, when the track materials 8, 9 thermally expand during high temperatures such as in summer, this expansion can be absorbed by the holes 7c, and furthermore, the track materials 8, 9, etc. If the connector 10 is damaged, the track material in that part can be removed by pulling out the connector 10, making it easy to repair the part.

FIG. 10 shows a modified example of the track material and sleeper used in the present invention. In this modified example, an inclined surface 27b is formed by chamfering on the front and rear ends of the upper surface of the connecting seat 27a of the sleeper 27. Upper and lower inclined surfaces 21b are formed by chamfering on the upper and lower surfaces of the front and rear ends of the wheel mounting portion 21a of the material 21.

In this modification, a horizontal running path is created in exactly the same manner as in the above embodiment, and when an inclined running path is created, as shown in the figure, the track material 21 is placed on the inclined surface 27b of the sleeper 27. The lower surface of the wheel rest part 21a of
The lower inclined surface 21b of the track material 21 may be brought into contact with the upper surface of the track member 7a, thereby making it possible to easily create an inclined running path. Further, as described above, in this case, the upper surface of the end of the track material 21 is chamfered, so that the end can be prevented from protruding from 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 are driven in. Although the case has been described in which the sleepers and track members are connected in advance by driving and then connecting them, the present invention may also be such that the sleeper timbers and the track members are connected in advance with connectors, and then the connecting units are driven at the same time. Furthermore, in the above embodiment, the sleeper wood and track material were installed by driving, but in the present invention, a groove corresponding to the shape of the sleeper wood and track material is formed, and the sleeper wood and track material are embedded in the groove. It can also be installed at

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 be applied to a running track for a four-wheeled vehicle that has four running trajectories. In this case, two track materials are provided for the front wheels and two track materials for the rear wheels, and the guiding material grooves are A recess may be provided in the center of each sleeper.

〔Effect of the invention〕

As described above, according to the method for constructing a running path for a lawn vehicle according to the present invention, sleepers are buried at predetermined intervals along the running line, and sleepers are buried at predetermined intervals along the running line. This was done by cutting the grass roots of the lawn so that the sections straddle each other, and driving flat sleepers whose lower ends were shaped like cutting edges into the cuts in the lawn, so that the lawn could not be peeled off. This only needs to be done on the track section where the wheels of vehicles pass, minimizing damage to the lawn when constructing the running track, and eliminating the need to form excavated grooves or construct the roadbed along the running track. This has the effect of greatly reducing construction time and construction costs.
