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.

[Conventional technology]

Recently, transport vehicles have been used at golf courses to transport cargo such as golf bags and personnel such as players and team members, 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 would be better to set up the above-mentioned running path relatively far from the fairway, but if this was done, it would take time to change clubs and play. 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.

[Problem to be solved by the invention]

However, while the conventional method described in this publication can reduce problems such as deterioration of the landscape of the lawn, as mentioned above, it is necessary to excavate a trench with a width approximately equal to that of the transport vehicle during construction. There is a problem in that it is inevitable that the road and the lawn in a relatively wide area in the vicinity will be damaged, and that it requires a great deal of effort and expense when creating it.

Therefore, the inventor of the present invention has solved these problems by minimizing the damage to the lawn during construction, and because it is extremely easy to connect the track materials and sleeper timbers, the construction time and construction time are reduced. We are developing a method that costs very little.

This method is a method for creating a running road for lawn vehicles, in which the grass part corresponding to each track is peeled off, the grass roots corresponding to the sleeper lines are cut, and then the track material,
The method involves burying sleepers and inserting connectors with locking parts and slits into the connection holes of the track material and sleepers, but this method only removes the grass from the track area, so this method is not suitable. Stripping work must be carried out for each track, and it is also necessary to cut the grass roots before burying the track materials and sleepers, which is time-consuming and labor-intensive. Furthermore, since the track material and the railroad ties are connected by connectors, there is a problem in that the connection strength is not sufficient and the reliability of the connection is poor.

This invention was made to solve the above-mentioned problems, and is suitable for lawn removal work, pillow timbers,
To provide a running road for lawn vehicles that can simplify the work of burying track materials, can connect the track materials and sleepers reliably and easily, and can significantly reduce construction time and construction cost. The purpose is to obtain a method for creating.

[Means to solve the problem]

A method for creating a running road for a lawn vehicle according to the present invention involves peeling off the lawn along a predetermined running line to a width approximately equal to the width of the running vehicle, and excavating and compacting the exposed roadbed portion. After laying sleepers and track materials on the roadbed in the excavated trench, the soil around them is backfilled and the lawn is restored to form a running road for vehicles. When laying the track material, the track material is placed over the sleeper timbers in correspondence with the wheels of the traveling vehicle, and then the threaded connectors are inserted and rotated into the connection holes formed in both members, and the sleeper timbers The two members are screwed together with a female screw inserted into the connecting hole to secure the two members together.

Further, in the method for constructing a running path for vehicles running on lawns, the present invention provides a method in which sleepers and track materials are connected in advance by screwed connectors to temporarily assemble a track block made of the above-mentioned two members, and the lawn is peeled off. After performing excavation and compaction, the temporarily assembled track blocks are placed side by side on the roadbed in the excavated trench, and then the adjacent temporarily assembled track blocks are stacked with one track material and the other pillow. It is designed to be connected to wood using the above-mentioned screwed connector.

In addition, the present invention provides the above-mentioned method for creating a running path for a lawn vehicle, in which in the track material laying work, several types of track materials with different lengths are used as the track material, and in the curved portion of the running line, the curvature of the track material is used as the track material. Short raceway materials are placed on the inside and long raceway materials are placed on the outside as appropriate.

[Effect]

In this invention, since the entire surface of the lawn is removed from the area that will become the running path for the vehicle, the grass removal work does not need to be done for each wheel track, but can be done at once. This eliminates the need to cut the grass roots before burying the grass, thereby improving the work efficiency of the grass stripping work and the work of burying track materials and sleeper timbers.

In addition, since the connection between the sleeper wood and the track material is performed by firmly tightening the sleeper wood and the track material by screwing together with the female thread of the screwed connector, the track material and the sleeper wood are firmly connected. It is possible to realize a connection structure in which sleepers and track members fixed to each other support each other.
As a result, the work of laying sleepers and track materials can be made as simple as placing them on the subgrade in an excavated trench, and the sleepers that serve as the foundation for the track materials can be made smaller, and the track bed can be used as a base for the track materials. This makes it possible to eliminate the need for support for timber, which reduces the depth of the excavated trench, and reduces the width of the excavated trench by making the sleepers more compact, thereby reducing trench excavation work and making construction work easier. It can be made even simpler, and furthermore, the cost can be reduced by simplifying the construction work.
Construction costs can be reduced by reducing material costs by making the sleepers smaller and more compact.

In addition, in this invention, the track block is temporarily assembled by tightening the sleeper timbers and the track material with screw connectors, and this temporarily assembled track block is placed and connected on the roadbed in the excavated groove. , by temporarily assembling sleeper timbers and track materials at the work site.
The work of laying sleeper timbers and track materials can be done in a short time, and when transporting and storing both of the above-mentioned members, they can be handled as individual members that are not bulky.
It does not burden the worker when carrying it around, and it does not require a large space for storage.

In addition, in the present invention, in the track material laying work, track materials of different lengths are used as the track materials, and in curved portions of the travel line, short track materials are placed on the inside as appropriate according to the curve, and longer ones are placed on the outside. Since the track materials are arranged, the curved portion of the travel line can be easily created with an appropriate radius of curvature by simply changing the type and arrangement of the track materials.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

1 to 11 are for explaining one embodiment of the present invention. Although not shown, a vehicle running on a road created by the method of this embodiment has rear left and right sides. The left and right rear wheels are located in the
It is a tricycle-type vehicle with a double-tire front wheel located at the center of the front.

First, the resin track block used in the method of this embodiment will be explained with reference to FIGS. 7 to 10. In these figures, 5 is a track block in the shape of a planar isosceles trapezoid, and 7 is front, rear, and middle sleeper timbers that are reinforcements for the left, right leg, and center of the trapezoid. The wood 7 is made of a thin rod-like body with a generally inverted convex cross section. The narrow portion 7d on the lower side of the sleeper 7 serves as a reinforcing portion of the sleeper 7. Connecting seats 7a and 7b are integrally formed on the left, right (top and bottom of FIG. 8) and center upper surfaces of the sleeper 7, and connecting holes 7c are formed in the connecting seats 7a and 7b. A female screw 7e is installed in this connecting hole 7c.

Between the left and right connecting seats 7a of the front and rear sleepers 7 are the upper and lower bases of the trapezoid, and the first and the lower bases are slightly wider than the left and right rear wheels of the vehicle. 2
Rear wheel track members 28a, 28b are installed, and a front wheel track member 9, which is slightly wider than the double tire type front wheels, is installed between the central connecting seats 7b. Both end portions and the center portion of 9 are connected to the connecting seats 7a, 7b by a threaded connector 10 such as a bolt and the female screw 7e.

In addition, the front wheel track material 9 and the rear wheel track material 28
As shown in FIGS. 8 and 10a and 10b, a and 28b are rod-shaped bodies with a horizontally elongated isosceles trapezoidal shape in plan and a T-shaped cross section, and the upper sides of the wheel rests 8a and 9a are located slightly on both sides. is inclined to be higher than the central part, and each of the placing parts 8a and 9a has a large number of truncated conical protrusions 8c and 9c protruding over the entire surface.
Moreover, the heights of these protrusions themselves increase successively from the center toward both left and right sides in a plane perpendicular to the running direction. In addition, each track material 28a, 28
Soil flow stops 8e, 9e are arranged at regular intervals in the traveling direction at b, 9, and are integrally formed between the protrusions arranged in a direction perpendicular to the traveling direction. In addition, each track material 28a, 28b, 9
Oval-shaped connection holes 10b, which are elongated in the track direction, are formed at both ends and at the center connection portion. Furthermore, guide material grooves 9d for mounting guide materials are recessed at both ends of the front wheel raceway material 9 and at the center of the connecting portion at the center. Further, the buried portions 8b, 9b, which are the vertical sides of the track members 28a, 28b, 9, serve as reinforcing portions to prevent deformation of the mounting portions 8a, 9a. And these track materials 28a, 28b, 9 are the grass 11a.
The upper ends of the projections 8c and 9c are exposed from the surface of the lawn 11a.

Next, the method of this embodiment using this trajectory block 5 will be explained.

FIG. 11 shows a golf course in which a driving path was created by the method of this embodiment, and 11 in the figure shows 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 road. A driving path 17 is created within the fairway 11 and runs vertically through the fairway 11.

The working steps of the method of this embodiment will be explained with reference to FIGS. 1 to 6. (1) First, a traveling line for the traveling vehicle is set, and a width equal to the vehicle width of the traveling trajectory of the traveling vehicle, that is, A groove 17 for arranging the track block 5 by peeling off the entire surface of the lawn 11a corresponding to approximately the same width as the track block 5, and excavating the exposed soil of the roadbed shallowly.
A is formed, and the depth of the subgrade in the groove is regulated and compacted to form a foundation subgrade 17b (Fig. 1 a, b).
reference).

(2) Next, sleepers 7 are arranged on the foundation roadbed 17b at equal intervals in a direction substantially perpendicular to the traveling direction of the traveling vehicle, that is, approximately along the multiple wheel trajectories created by one traveling vehicle. A sleeper line that intersects at equal intervals is set, and the sleeper 7 is arranged along this sleeper line, and then the first and second rear sleepers are placed on the sleeper 7 along the travel trajectory of the rear and front wheels of the vehicle. The wheel raceway members 28a, 28b and the front wheel raceway member 9 are arranged (see FIGS. 1c and d).

Here, the traveling path 17 has a straight section and a curved section, but in this embodiment, in the work of arranging track materials for the straight section, short sections are placed on each side of the straight section as shown in Fig. 3. The first rear wheel track material 28a on the one side and the second rear wheel track material 28 on the longer side.
In addition, in the track material arrangement work on the curved road section, the shorter first track material 28a is placed on the inside of the curved road as shown in FIG.
, and the longer second track member 28b is successively placed on the outside thereof.

Thereafter, as shown in FIG.
8b, 9, and the connecting holes 7c of the connecting seats 7a, 7b of the sleeper 7,
The female screw 7e is rotated and inserted into the connecting hole 7c.
conclude with.

(3) Finally, if you backfill with soil up to the height of the top surface of the track material placed on the foundation subgrade 17b and cover the entire surface including the top surface of the track material, or cover the soil area excluding the track material portion, the above-mentioned Raceway material 28
The protrusions 8c, 9c of a, 28b, 9 are exposed from the lawn (FIGS. 5 and 6), and in this way, the running path 1 is exposed along the running line.
7 is formed.

In this way, in the method of this embodiment, the entire surface of the lawn that will become the running path for the vehicle is removed, so the lawn removal work does not have to be carried out for each wheel track of the vehicle, but can be done at once. In addition, there is no need to cut the grass roots before burying the track materials and sleepers, and since the excavation depth of the track placement groove 17a is shallow, the amount of backfilling soil can be reduced. It can improve the workability of burying work.
In addition, since the track material and the sleeper wood are connected by a threaded connector and a female screw inserted into the connection hole of the sleeper wood, these members can be connected reliably with sufficient strength, and the connection work is relatively easy. It can be carried out.

That is, by firmly fixing the track material and the sleeper material in this way, it is possible to realize a connection structure in which the sleeper material and the track material support each other.
With this connection structure, the work of laying sleepers and track materials can be made as simple as arranging them on the roadbed in an excavated trench, and the sleepers that serve as the foundation for the track materials can be made smaller and It becomes possible to eliminate the need to support the track material by the floor part, which reduces the depth of the excavated groove, and reduces the width of the excavated groove by making the sleepers smaller, thereby reducing trench excavation work. The construction work can be made even easier, and the construction cost can be reduced by reducing costs by simplifying the construction work and by reducing material costs by making the sleepers smaller and more compact. can.

Further, in the vehicle running path of this embodiment, since the track block 5 has an isosceles trapezoidal shape, both straight road sections and curved road sections can be easily and reliably constructed.

In other words, in the curved portion of the running line, by placing short track materials on the inside and long track materials on the outside, depending on the curvature, the creation of the curved portion of the travel line can be adjusted according to the type of track material. This can be easily done by simply changing the radius of curvature. Also, in this trajectory block 5,
Since the sleepers 7 are arranged not only on both ends of the track materials 28a, 28b, and 9 but also in the center, the wheel mounting portions 8a, 9a and reinforcing portions 8b, 9b of the track materials can be made thinner, and the sleeper materials can be made thinner. 7 itself is thin,
Significant weight reduction can be achieved. Further, in each of the raceway members 28a, 28b, 9, the protrusions 8c, 9c
The wheels are gradually higher from the center toward both sides, which prevents wheels from coming off on sideways slopes and curves of the running path 17, and increases the installation area of the wheels, improving braking performance. Moreover, since these track materials are provided with flow stops 8e and 9e at regular intervals, the soil on the track materials will not be washed away by rainwater.

Further, after construction, the only exposed objects are the protrusions 8c and 9c, which are hardly visible to the player and therefore hardly spoil the landscape of the lawn. Furthermore, the connection hole 1 of the connection part of the raceway members 28a, 28b, 9
0b has an oval shape, so when the raceway material expands during high temperatures in summer, this expansion is absorbed by the connecting hole 1.
It can be absorbed by the track material 28a,
28b, 9 etc. are damaged, the above connector 10
By removing the track material, the track material can be replaced, making repair work easier.

In addition, in the above embodiment, the case where the track material laying work is performed after the sleeper timber laying work is performed is shown, but these works may be performed at the same time.In other words, one of the front and rear sleeper timbers 7 and The track blocks 5 may be temporarily assembled by assembling the track materials 28a, 28b, 9 to the central sleeper 7, and this temporarily assembled track block may be placed and connected within the foundation subgrade 17b; in this case. Work time can be significantly reduced.

In other words, until the track blocks are temporarily assembled at the work site, they can be handled separately as bulky track materials and sleepers, which can be a burden on workers when carried, and require a large storage space. Furthermore, when laying the track materials and sleepers, the construction work can be completed in a short time by assembling them in advance at the work site and keeping them in a temporarily assembled state.

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 single-tire front wheel. Furthermore, the present invention can also be applied to a four-wheel vehicle type vehicle running track where four running trajectories occur; in this case, two track materials for the front wheels and two track materials for the rear wheels are provided,
Further, the guiding material groove may be recessed in the center of each sleeper.

Furthermore, in each of the above-mentioned embodiments, a case was explained in which a running path for vehicles was created at an existing golf course.
The basic land preparation method of the present invention can also be applied to creating a driving path on a golf course under construction, that is, a course without grass. A shallow part of the ground corresponding to the width of the running vehicle is excavated, and the course is then compacted, the sleepers and track materials are laid, the sleepers and track materials are connected, and the soil is backfilled. At the time of turfing, it is sufficient to turf this part of the running path as well. In this case, the same effects as those of the above embodiments can be obtained except for the above-mentioned lawn removal work.

〔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 entire lawn of the portion that will become the running path for the vehicle is removed, so the lawn removal work is carried out for each wheel track. It does not need to be done and can be done all at once, and there is no need to cut the grass roots before burying track materials and sleepers, which improves the work efficiency of lawn stripping work and work of burying track materials and sleepers. effective.

In addition, since the connection between the sleeper wood and the track material is performed by firmly tightening the sleeper wood and the track material by screwing together with the female thread of the screwed connector, the track material and the sleeper wood are firmly connected. It is possible to realize a connection structure in which sleepers and track members fixed to each other support each other.
As a result, the work of laying sleepers and track materials can be made as simple as placing them on the subgrade in an excavated trench, and the sleepers that serve as the foundation for the track materials can be made smaller, and the track bed can be used as a base for the track materials. This makes it possible to eliminate the need for support for timber, which reduces the depth of the excavated trench, and reduces the width of the excavated trench by making the sleepers more compact, thereby reducing trench excavation work and making construction work easier. It can be made even simpler, and furthermore, construction costs can be reduced by reducing costs by simplifying the construction work and by reducing material costs by making sleepers smaller and more compact. .

Further, according to the present invention, in the above-mentioned method for constructing a running path for lawn vehicles, the track block is temporarily assembled by tightening the sleeper timbers and the track material using screwed connectors, and the temporarily assembled track block is inserted into the excavated groove. Since they are placed and connected on the roadbed in the middle of the road, the work of laying the sleepers and track materials can be done in a short time by temporarily assembling the sleepers and track materials at the work site. When transporting or storing the product, it can be handled as a bulky individual member, which has the advantage of not being a burden to workers when carrying it or requiring a large space for storage.

Further, according to the present invention, in the method for creating a running road for lawn vehicles, in the track material laying work, track materials of different lengths are used as the track materials, and in the curved portion of the running line, the curvature In addition, we placed short track materials on the inside and long track materials on the outside as appropriate, making it easy to create curved sections of the running line by simply changing the type of track material and the way it is arranged. However, there is an effect that can be applied.
