Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for transporting a relatively small-sized plant in an area with poor transportation in an underdeveloped country.

<Prior art and its problems> The cost required for conventional plant construction, especially when building in a relatively underdeveloped region, is
(Civil work, installation, etc.) will be enormous, and if you include the cost of transporting various materials to the site, the cost may exceed the cost required to procure the plant equipment itself.

In other words, on-site costs account for more than half of the total plant construction cost, and this trend has become increasingly strong recently, becoming a factor that worsens the economic efficiency of plants.

Moreover, in such areas, gathering a large number of highly skilled construction engineers is not only expensive but also extremely difficult, which can lead to technical problems at construction sites. Even if sophisticated equipment is delivered, it is often the case that it is not able to fully demonstrate its functions.

Even so, in the case of relatively large plants, the problem is not so big because the proportion of construction costs in the product cost is relatively small, but in the case of relatively small plants, the proportion of construction costs is unavoidable. This increases the cost of the product and makes it uncompetitive.

In order to solve these problems, the entire plant was
The so-called purge method, in which the purge is placed on two purges, and the so-called module construction method, in which it is placed on multiple large common platforms, have also been put into practical use.This method significantly reduces construction costs on site and shortens the delivery time. On the one hand, it has the advantage of shortening the construction process and eliminating many technical problems, but on the other hand, it is difficult to transport modules to the site, so transportation costs are relatively high, and these construction methods can only be used in areas such as coastal areas. The drawback is that it is extremely limited, such as by a large river.

Furthermore, since areas with small demand units that require small-scale plants are usually relatively remote locations away from waterfronts such as coasts, it is natural that the purge method and module construction method described above are suitable. It is unsuitable for application and puts pressure on the economics of building increasingly small plants.

<Purpose of the Invention> The present invention has been made in view of the above-mentioned problems, and when constructing various types of plants, especially relatively small-sized plants, the present invention reduces costs related to on-site construction, installation, etc. as well as transportation costs. The purpose of the present invention is to provide a method for economically constructing various plants.

<Means for Solving the Problems> In order to achieve the above object, the plant transportation method of the present invention is such that a steel frame structure to be used as a platform for installing plant equipment is transported at a plant construction site. The system is characterized in that a required number of containers are made roughly according to the dimensions of the container, and plant structures such as equipment, piping, and construction materials are stored in the framework structure and transported to the construction site.

That is, the plant construction method according to the present invention basically takes advantage of the various advantages of the modular construction method (reduced construction costs, short delivery times, ensuring quality, etc.), while also addressing its disadvantages:
The aim is to eliminate soaring transportation costs and restrictions on installation locations.

Therefore, each piece of equipment that makes up the plant is planned to be placed in an extremely limited space, as in the case of the module construction method.

<Example> An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a plant embodying the concept of the present invention;
FIG. 2 is a perspective view showing equipment installed on a container-sized frame structure according to the transportation method of the present invention.

In Figures 1 and 2, reference numeral 1 denotes a frame structure made of structural steel or the like sufficiently strong to match the dimensions of one or more types of shipping containers, preferably the dimensions of a standard container. Adapted.

The frame structures 1 are later connected at a construction site by arranging the necessary number of them in a pre-planned order in the form of a platform, as shown in FIG. The upper surface of the container-like framework 1 is
It is processed (the holes are only processed) so that each equipment 3 can be installed therein. For small equipment 3,
As shown in FIG. 2, it is planned to be installed via an appropriate small base plate (substitute for a civil foundation) 2 as required. The framework structures 1 are bolted together if necessary, but remain separated in the presence of vibration sources.

The frame structure 1 stores equipment 3, piping, construction materials, etc. therein, and is used as a container for transportation to a construction site. In order to effectively pack and unpack these items to be transported, the reinforcing member 4 of the frame structure 1 may be made removable. Furthermore, the holes for attaching each of the equipment 3 described above can be used to secure the transported object to the framework structure 1.

Furthermore, if the size of the container-like framework 1 is made the same as the size of a standard container, existing cargo handling equipment (yards, cranes, trailers, etc.) can be used as is. Furthermore, for remote areas, a trolley (not shown) may be attached directly to the frame structure 1 and transported from a port to a construction site.

At a construction site, only level and level ground is required to accommodate the extremely limited space described above. This ground only needs to be leveled to the extent that it has been rolled over, and there is no need to take any reinforcing measures such as piling unless it is extremely soft.

<Effects of the Invention> As described above, the plant transportation method of the present invention has the following effects.

(1) The framework structure is connected to plant equipment, piping,
By using it as a container for transporting construction materials, etc., it is not only possible to reduce direct costs such as packaging, but also by making its dimensional specifications match those of conventionally used standard containers. , existing cargo handling equipment can be used, further contributing to rationalization of transportation and cost reduction.

■ Simply arrange the frame structures on leveled ground;
Since it is used as a base for the plant in place of the civil foundation, the cost of the current civil construction work can be significantly reduced, which greatly contributes to reducing the total construction cost.

■ The unused space inside the frame structure can be used as a storage tank for raw materials or products, or as various facilities (electrical room, operation room, warehouse, etc.), so the entire plant can be can be placed in a more limited space.
