Description

  The present invention relates to a traffic system at a construction site, and more particularly, to a traffic system used at an additional construction site for plant equipment such as a power plant.

  Generally, in various plants such as nuclear power plants, thermal power plants, chemical plants, etc., plant facilities are often expanded, and when installing plant facilities adjacent to existing plant facilities, In addition, there are not only general vehicles that go in and out of the existing plant equipment, but also construction vehicles that go in and out of the construction site of the extension plant equipment.

  By the way, when performing expansion work with a super large facility such as a plant, a vehicle such as a huge dump truck (for example, a 45-ton dump truck) is often used as a construction vehicle. It is extremely dangerous when mixed with vehicles.

  Therefore, conventionally, when a construction vehicle needs to pass through the area of existing plant equipment or when a general vehicle passes through the area of additional plant equipment, it is a safety measure against an increase in traffic volume and the passage of large construction vehicles. In addition, traffic lights and traffic guides are arranged to perform traffic control and vehicle guidance.

  On the other hand, a transportation system for pedestrians, vehicles, supplies, etc. on slopes is known. In this transportation system, a terminal is provided in contact with a road near the slope, and a general parking lot and a commercial parking lot are provided. We are going to install.

  In this transportation system, passenger elevators and vehicle / material transport cables are installed in the aerial direction starting from the terminal, and connected to the general parking lot and the commercial parking lot. The road for pedestrians and vehicles is installed on the ground or on the ground so as to follow the contour line as the lateral movement line, and the three-dimensional intersection with the longitudinal movement line, and each of them is the movement line to the passenger elevator and the vehicle / material transportation cable. (For example, refer patent document 1).

  However, when installing additional plant equipment adjacent to the existing plant equipment, including the construction site of this additional plant equipment, that is, associating the existing plant equipment with the construction site, depending on the arrangement of traffic lights and traffic directors If you try to guide the vehicle, traffic constraints will inevitably occur with the construction work of the additional plant equipment, and if you try to operate the existing plant equipment as before, the operational costs of the existing plant equipment will increase. There is a problem that increases.

  Furthermore, to prevent accidents, traffic lights and traffic directors must be assigned, and compared to the case of constructing a new plant facility, there are general vehicles coming in and out of the existing plant facility. The cost will increase. And even if it arrange | positions a traffic light and a traffic guide, there exists a subject that anxiety remains in terms of traffic safety as a result of mixing a large construction vehicle and a general vehicle.

  Therefore, an object of this invention is to provide the traffic system which can aim at traffic safety, suppressing the increase in the operating cost of existing plant equipment, and the construction cost of expansion plant equipment.

  (1) The present invention is a traffic system used when constructing an extension plant facility adjacent to an existing plant facility in a plant, the first road passing through the site of the plant, and the first And a second road connected to the three-dimensional intersection, and the construction vehicle used for the construction of the additional plant facility is the first road or Only one of the second roads is allowed to pass.

  In the traffic system described in (1), the construction vehicle is connected to the first road passing through the plant by crossing the second road via a three-dimensional intersection. Since only one of the road and the second road is allowed to pass, if the general vehicle mainly passes the second road, it will be a construction vehicle, in particular, a large construction vehicle and a general vehicle. As a result, the increase in the operation cost of the existing plant equipment and the increase in the construction cost of the extension plant equipment can be suppressed, and traffic safety can be achieved.

  (2) The present invention is the transportation system according to (1), wherein the existing plant equipment is positioned on both sides of the first road, and the second road is installed through the three-dimensional intersection. It is provided to connect plant facilities to each other, and the construction vehicle is allowed to pass only on the first road.

  In the transportation system described in (2), when the existing plant equipment is positioned on both sides of the first road, the second road is provided so as to connect the existing plant equipment to each other through a three-dimensional intersection, Since the construction vehicle is allowed to pass only on the first road, the construction vehicle is rarely mixed with ordinary vehicles, and the construction vehicle does not pass through the three-dimensional intersection. The part can secure the structural safety.

  (3) The present invention is the transportation system according to (2), wherein a general vehicle entering and exiting the existing plant facility moves between the existing plant facilities through the second road and the three-dimensional intersection. It is characterized by.

  In the traffic system described in (3), since the general vehicles entering and exiting the existing plant facilities move between the existing plant facilities through the second road and the three-dimensional intersection, Can be reliably separated to prevent the construction vehicle and the general vehicle from being mixed.

  (4) In the traffic system according to (3), the present invention is characterized in that a mark is provided on the general vehicle when the general vehicle passes through the first road.

  In the transportation system described in (4), when a general vehicle passes through the first road, a mark is provided on the general vehicle. Therefore, a driver of a construction vehicle, in particular, a large construction vehicle is generally used. Traffic safety can be ensured without overlooking the vehicle.

  As described above, according to the present invention, the second road is three-dimensionally intersected with the first road passing through the plant via the three-dimensional intersection, and the construction vehicle is the first road. Or, since only one of the second roads is allowed to pass, there are few cases where construction vehicles and general vehicles are mixed, and as a result, the operating cost of the existing plant equipment and the construction cost of the additional plant equipment are reduced. There is an effect that traffic increase can be achieved by suppressing the increase.

  In FIG. 1, the illustrated plant is, for example, a power generation system (power plant), and this plant has plant facilities such as a plurality of buildings (hereinafter referred to as existing plant facilities) 11 constructed on the ground. is doing. On the other hand, in the plant, a plant facility such as another building (hereinafter, this plant facility is referred to as an extension plant facility) 12 may be added adjacent to the existing plant facility 11.

  When the expansion plant facility 12 is expanded adjacent to the existing plant facility 11, not only there are general vehicles that enter and exit the existing plant facility, but also there are construction vehicles that enter and exit the construction site of the expansion plant facility. There is a large vehicle such as the 45t dump truck described above as a construction vehicle that enters and exits the construction site.

  In the plant shown in FIG. 1, a main road (first road) 13 is laid along the existing plant equipment 11 and the extension plant equipment 12 (construction site). A sub-road (second road) 14 that enters and exits the plant facility 11 is provided. These secondary roads 14 are connected to each other by a three-dimensional intersection 15 that straddles the main road 13 (connected).

  Referring to FIGS. 2 and 3, parking lots 16 are provided around the building of the existing plant equipment 11, and ordinary vehicles other than construction vehicles park using these parking lots 16. That is, ordinary vehicles entering and leaving the existing plant equipment 11 use these parking lots 16. And in the existing plant equipment 11, when a general vehicle moves from the building located on one side of the main road 13 to the building located on the other side of the main road 13, the secondary road 14, the three-dimensional intersection 15 and the sub-road 14 will be moved. That is, the general vehicle moves through the three-dimensional intersection 15 without actually crossing the main road 13.

  As shown in FIG. 3, the sub road 14 is formed on an inclined portion 14a that forms an inclined surface. The three-dimensional intersection 15 straddles the main road 13 by the bridge pier 15 a, and the plurality of secondary roads 14 are connected to each other by the three-dimensional intersection 15. That is, the secondary road 14 passes above the main road 13 by the three-dimensional intersection 15.

  Referring to FIG. 4, FIG. 4 (a) is a diagram showing an example of a 45 ton (45t) dump truck 21. The dump truck 21 has a height of 4.4 m and a width of 5.1 m, It is a construction vehicle used exclusively for the construction of the extension plant equipment, and only the main road 13 shown in FIG. 3 is allowed to pass, and the sub-road 14 and the three-dimensional intersection 15 are not allowed to pass.

  FIG. 4B is a diagram showing an example of the 10t dump truck 22. The dump truck 22 has a height of 3.1 m and a width of 3.0 m, and is used for the construction of additional plant equipment. Here, it is included in general vehicles. Therefore, the dump truck 22 is allowed to pass not only the main road 13 shown in FIG. 3 but also the secondary road 14 and the three-dimensional intersection 15.

  FIG. 4C is a diagram showing an example of the 4t truck 23. The truck 23 has a height of 2.5 m and a width of 2.2 m, and mainly includes the secondary road 14 and the three-dimensional intersection 15. It is included in general vehicles that are allowed to pass. FIG. 4D is a diagram showing an example of the ordinary passenger car 24. The ordinary passenger car 24 has a height of 1.4 m and a width of 1.7 m, and mainly includes the sub road 14 and the three-dimensional intersection. It is included in general vehicles that are allowed to pass through the section 15.

  Also in the truck 23 or the ordinary passenger car 24, it is necessary to temporarily enter and exit the construction site in connection with the expansion work of the expansion plant equipment (for example, the presence of the work). That is, it is necessary to pass through the main road 13.

  In such a case, since it is difficult to see a general vehicle from the driver's seat of the 45t dump truck 21, for example, as shown in FIG. 4 (d), a flag 24a is attached to the roof of the ordinary passenger car 24 as a mark. . When the flag 24a is attached, the height of the ordinary passenger car 24 is 3.0 m. Similarly, the flag 23a is attached to the roof as a mark when the 4t truck 23 enters and exits the construction site.

  As described above, when the construction of the extension plant facility 12 is performed adjacent to the existing plant facility 11, the construction vehicle is connected to the main line by separating the traffic between the general vehicle and the construction vehicle by the three-dimensional intersection 15. The general vehicle moves in and out of the construction site through the road 13 and moves between the existing plant facilities located on both sides of the main road 13 through the sub road 14 and the three-dimensional intersection 15.

  For example, as shown in FIG. 5, the 45-ton dump truck 21 passes through the main road 13 toward the construction site, and the 10-ton dump truck 22 and the ordinary passenger car 24 move between the existing plant facilities 11 (the existing plant facilities). (When entering and exiting the vehicle), the vehicle travels through the secondary road 14 and the three-dimensional intersection 15 so that the 45t dump truck 21 and the ordinary passenger car 24 do not encounter the same plane, and the 45t dump truck 21 operates. Drivers such as hands and ordinary passenger cars 24 can travel on the road with peace of mind.

  As described above, in the traffic system according to the present embodiment, when the expansion plant facility 12 is expanded adjacent to the existing plant facility 11, the existing plant facility and the construction site are associated with each other, and the traffic lights and traffic guides are arranged. This eliminates the need to guide the vehicle. As a result, traffic restrictions do not occur with the expansion work of the extension plant facility 12, and the operation cost of the existing plant facility 11 does not increase.

  And even if general vehicles come in and out of existing plant equipment, general vehicles and construction vehicles are separated, so there is no mixing of large construction vehicles and general vehicles. Anxiety is resolved. That is, according to the embodiment of the present invention, it is possible to suppress the increase in the operating cost of the existing plant equipment 11 and the construction cost of the additional plant equipment 12 and to achieve traffic safety.

  Further, in the above-described embodiment, the large construction vehicle such as the 45t dump truck 21 does not pass through the three-dimensional intersection 15, so that an excessive load is not applied to the pier 15a and the like, and the structure of the three-dimensional intersection 15 is provided. The above safety can be ensured.
