BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant construction method and construction equipment.

[0002]

2. Description of the Related Art In the construction of a conventionally known nuclear power plant, in order to carry a large product into a nuclear power plant building, a reinforced ground is constructed outside the building and a large mobile crane is operated. This is used to carry in a product, or a lifting jig dedicated to carrying in a specific large product (for example, a lifting device for setting RPV) is installed to take in and carry in a product.

Further, when carrying in a large-sized product to be transported by sea, the product loaded at a port facility provided in the vicinity of a construction plant is once lifted up to the ground and a land transportation means such as a transporter is used. After moving to a large crane operating range, the crane was hoisted and the hoisting procedure was carried out at a predetermined position in the building.

In the case of hoisting a product which requires erection, the erection yard is secured within the range where the crane can be loaded, the product is made into a large block and modularized, and the product is hoisted by the crane, and the predetermined yard inside the building is set. I used the method of hanging in position.

Further, in order to set and dismantle a large-sized lifting machine for carrying in products, a large flat site was constructed, and a large-sized lifting machine was assembled on it and an auxiliary heavy machine for dismantling was operated.

Further, a large mobile crane used in a conventionally known construction method for a nuclear power plant,
The tower crane has a smaller lifting capacity as the distance from the installation position increases.For products that are located outside the lifting capacity range of the lifting machine, they can be moved to a predetermined setting position by means such as roller pulling. Was there.

Further, in Japanese Patent Laid-Open No. 56-141592, when constructing a reactor building of a nuclear power plant, a gate crane is arranged so as to run across the reactor building from an adjacent processing site. It is disclosed to bring the product to be used for construction to the construction position.

In order to carry out the conventionally known method for constructing a nuclear power plant, first,
In order to install or operate a large lifting machine used for construction, it is necessary to provide a vast temporary yard near the construction site. Even when trying to apply the modular construction method in which the product is made into a large block and is carried into the building, a large temporary yard is also required near the construction site, and it is difficult to secure a large temporary yard on a narrow site. If it is secured, the economic burden is large and it is uneconomical.

Therefore, there is a demand for a method of constructing a nuclear power plant on an economical and narrow site that does not require a vast temporary site in the vicinity of the building.

Further, in the conventionally known method of constructing a nuclear power plant, the product transported by sea must be drained once at the port facility and then transported by land to the operating range of the crane. Therefore, it was necessary to secure a transportation route from the port facility to the crane operating range, and it was necessary to construct roads and adjust the yard accordingly.
In addition, land transportation is uneconomical because it is necessary to secure transportation means such as large trailers and transporters and to secure transportation roads.

Therefore, there is a demand for a construction method which is economical and can shorten the process by reducing the land transportation of the product members at such a site.

Mobile cranes and tower cranes used in conventional construction methods have a lower lifting capacity as the distance from the installation position of the crane increases. Does not contribute to the setting. In addition, the products installed in the nuclear power plant are
Many of them are heavy in weight, and in the future, it is strongly required to further reduce the installation man-hours at the construction site.Therefore, multiple products should be assembled before being carried into the site and then carried into the building. The modular construction method is often used. Therefore, it is desirable that the lifting capacity of the crane is large in the entire construction building. In order to fulfill this hope, it has been conventionally proposed to install a gate crane across the buildings so that it can run freely and use the gate crane for cargo handling for construction work. Doing is uneconomical. Therefore, there is a demand for construction technology that can economically support the large block module construction method, which is expected to have a wider range of application in the construction of nuclear power plants.

BEST MODE FOR CARRYING OUT THE INVENTION Construction of a nuclear power plant using the combination of the I-type arrangement and the gate crane of the present invention will be described below with reference to the drawings.

Various patterns can be considered for the arrangement of the nuclear power plant to which the present invention is applied, but in the present embodiment, the plot plan shown in FIG. 1 is used as the basis.

In the nuclear power plant described in this embodiment, the heat exchanger equipment, the turbine (generator) equipment, and the reactor equipment are arranged in series in this order from the side near the coastline 91 in the longitudinal direction (type I). Placement) of the plot plan is applied.

Further, the reactor facility constitutes the reactor building 1 with a single building.

The nuclear power plant to be constructed is a twin implant, and the waste treatment building 3, the control building 4, and the service equipment, which are common equipment for the odd number unit 81 and the even number unit 82, are arranged in the middle of the two units. Shows the case.

In the following explanation, an embodiment of the present invention will be explained based on the plot plan shown above.

FIG. 2 shows a gate crane 11 used in the present invention.
It shows an outline of.

The traveling rail 21 on which the portal crane 11 is set and travels is installed along the outer wall in the longitudinal direction (serial direction) of the reactor building 1 and the turbine building 2 which constitute the nuclear power plant.

The gate-type crane 11 is equipped with a gate-type structure as a frame when viewed from the traveling direction, and is equipped with a traveling device 22 at the lower part of the vertical leg structure so that it can travel by itself.

The main body of the gate crane 11 is installed so as to straddle the nuclear power plant stand (reactor building 1, turbine building 2).

The portal crane 11 is provided with an upper girder of the frame so that the trolley can traverse in the horizontal direction perpendicular to the traveling direction of the portal crane 11 by the traverse device 23.

The trolley is equipped with a hoisting device 24 so that the hoisted product 51 and construction materials can be hoisted to any position in the construction building.

By the way, when the gate crane 11 is arranged so as to straddle the reactor building 1 and the turbine building 2 in the plot plan of the I type tool implant shown in FIG. 1, the entire area of the reactor building 1 and the turbine building 2 Is covered in the operating range of the gate crane 11, whereas the waste treatment building 3
Then, the control building 4 is completely out of the operating range of the gate crane 11, and the product 51 and materials cannot be carried in.

Therefore, an overhanging arm structure 25 is provided from the portal type main body structure of the portal crane 11, and a trolley equipped with a traverse device 23 and a hoisting device 24 is traversably provided in this portion, whereby the portal crane 11 is provided. The product 51 and materials can be carried into an area outside the operating range of the main body.

FIG. 3 shows an example of the portal crane 11 provided with the projecting arm structure 25 so that the product 51 and the material can be carried into the waste treatment building 3 and the control building 4 side.

If the projecting arm structure 25 and the trolley with the traversing device and the hoisting device are provided on the side opposite to that shown in FIG. 3, the on-site transformer 5 and the main transformer 6 adjacent to the odd number machine side 81 are provided. It can also be applied to the installation and installation of transformer equipment.

In the construction of a nuclear power plant, in addition to heavy products, a large number of products and members must be carried into the building in large quantities.

Although the large-sized gate crane 11 is suitable for carrying in a heavy product, it is not suitable for carrying in several products because of its low speed.

Therefore, in order to carry in several products to the nuclear power plant under construction, a method of installing a tower crane 14 in addition to the gate crane to carry in products and members can be considered.

To carry in products and members using the tower crane 14, a truck or transporter 1 is used.
The products and components that were brought to the vicinity of the nuclear power plant under construction in 5 were lifted over the rails of the gate crane,
Bring in.

It shows the situation that they are arranged so as to pass through.

FIG. 8 shows a portal crane 1 applied to the present invention.
1 shows an example of a method for setting 1 in the operation site.

When the members constituting the gate crane 11 used in the present invention are transported by sea, if a large ship is used,
It can be mounted as a fairly large member.

In the conventionally known crane setting method, the crane constituent members are once lowered from the sea to the land, transported by land, and assembled and set near the construction site.
As shown in, if the traveling rails 21 of the portal crane 11 are extended to the vicinity of the coastline 91, which is a quay, the components of the portal crane 11 that have been transported by sea can be transferred to the sea by using the floating crane 12. It is possible to set it by lifting it from the top and hanging it on the traveling rail 21.

In this case, the yard for assembling the crane, which was required in the conventional crane setting, is not required.

As a method of setting the gate crane,
It is also possible to use a crane (tower crane, mobile crane, etc.) provided on the land side to lift the gate-type crane constituent members from the ship and to set them down on the traveling rail 21 of the gate-type crane.

FIG. 9 shows an example of the arrangement of the nuclear power plant and the gate crane 11 in consideration of the product loadability.

One of the objects of the present invention is to efficiently carry products (especially large products) transported by sea into a building under construction.

Large products that cannot be transported by land are coastal ships,
Alternatively, it is transported to the construction site (site port) by sea transportation using the barge 13.

In this figure, the traveling rail 21 of the portal crane 11 is installed so as to extend to the sea portion, and the portal crane 1 is installed.
1 is capable of traveling to the sea, and a coastal ship or a barge ship 13 loaded with products 51 is a gate-type crane 11
It is possible to enter below the operating range.

The gate-type crane 11 moves to a position directly above the product 51 to be picked up, hoists the product 51, moves to the loading position of the product 51, and sets the hoisting position.

As shown in FIG. 9, an entry passage 94 for the product transport ship is provided continuously to the seawater intake passage 93 of the nuclear power plant.
Both sides of the approach path 94 are surrounded by a structure that supports the extended portion of the traveling rail 21 to the sea, and contributes to secure a quiet area of seawater intake during operation of the power plant.

Next, the arrangement pattern of the ground yard 95 of a large module product will be described.

In the conventional module construction method using a large-sized mobile crane or tower crane, the module groundwork area needs to be arranged within the crane lifting capacity range.

However, according to the present invention, it is possible to directly load the large-sized products transported by sea from the product transport ship, so that it is far from the construction site (module factory, etc.).
The large module assembled in 2 above may be directly loaded from the product transport ship and brought to the installation location.

Therefore, no module assembly yard is required near the site.

However, when the products 51 transported by land are assembled and modularized near the construction site, if the rails for traveling the gate crane 21 are extended to the module assembly area, the products 51 transported by land, Alternatively, the product 51 assembled in the field yard can be hoisted by the gate crane 11 and carried into the set place.

In FIG. 10, the traveling rail 21 for operating the portal crane is extended to the yard portion 95, and the products transported by land and the large-scale assembled module are hoisted by the portal crane 11 and traveled on the portal crane 11. It shows the situation in which it is hung down and loaded into the building.

Next, a method of effectively using the gate crane 11 to set a large product 51 outside the building range will be described.

Due to its nature, the gate crane 11 has a large hoisting ability for products located within the operating range of the crane, but if it deviates from the operating range even a little, it becomes impossible to load it at all. .

The portal crane 11 described so far.
For the reactor building 1 and the turbine building 2,
All areas are included in the operating range of the gate crane 11,
The region sandwiched between the odd-numbered units 81 and the even-numbered units 82 in the twin implant arrangement is out of the operating range of the portal crane 11.

However, in order to make it possible to carry the heavy product 51 into the large product 51 installed in the waste treatment building 3 or the control building 4 and to shorten the construction period, it is included in the operating range of the gate crane. Should be devised.

FIG. 11 shows a rail 21 for running a gate type crane.
1 on the waste treatment building 3 and control building 4 side
The figure shows an arrangement in which the products 51 can be loaded in a range sandwiched between the odd-numbered machines 81 and the even-numbered machines 82 by being assembled and installed.
