Description

TECHNICAL FIELD The present invention relates to a method for constructing a structure that requires rigidity, such as a warehouse such as an explosives store and an ammunition store.

<Prior art> Among various warehouses, in particular, explosives and ammunition storage, as shown in Fig. 4, is an underground type in which a concrete building K is built in the tunnel T for the safety measures of the surroundings. Has been adopted.

<Problems to be Solved by the Present Invention> The above-mentioned underground warehouse has the following problems.

(B) The moisture that permeates the concrete wall of the building in the tunnel raises the temperature in the warehouse, and the heat insulation property of the concrete is not good, so the internal temperature in the warehouse drops and dew condensation occurs. May adversely affect the storage state of.

(B) In order to construct a concrete structure in the tunnel, a work space is required above the tunnel, and the volume of the structure is limited accordingly.

(C) In an explosives storage or ammunition storage, which are often used in underground warehouses, in the unlikely event of an accident such as an explosion, the buildings may be scattered and the damage may increase.

<Purpose of the invention> The present invention has been made in view of the above points, and prevents adverse effects on the storage state of storage materials due to temperature, dew condensation, etc., and does not leave a wasteful space in the tunnel. It is an object of the present invention to provide a method for constructing a warehouse or the like, which can have a large volume in the warehouse and can minimize the damage in the event of an accident or the like when used for an explosives warehouse or the like.

It is another object of the present invention to provide a method of constructing a warehouse or the like, which can be constructed not only in a tunnel but also generally outside.

<Means for Solving Problems> The present invention relates to a method for constructing a structure requiring rigidity such as a warehouse, in which a plurality of hermetically sealed tube groups are arranged and both sides of the tube groups are impermeable. Use a flexible continuous structure covered with a sheet and formed on the outer shell of a warehouse to be constructed, and partition it with a tube so that the curable fluid and air do not mix in the contracted continuous structure. It is a method for constructing a warehouse or the like, which is characterized by injecting and raising a continuous structure into a predetermined shape for construction.

<Example> Next, of the construction methods of the present invention, a construction method of an underground warehouse will be described as an example based on the drawings.

(A) Illustration of the whole In the underground warehouse of the present invention, as shown in FIG. 1, the tubes 1 having a membrane structure are juxtaposed to each other and connected by two impermeable wall sheets S, and inside a predetermined tunnel T. The continuous structure A having a similar shape is installed in the tunnel cross section.

Note that FIG. 1 shows a state in which the curable fluid is expanded without being injected for the sake of description.

(B) Tube The tube 1 is a hermetically sealed cylinder having a membrane structure with both ends closed, and is a member that functions as an inverted U-shaped column by injecting air and a curable fluid into the inside.

If the total length thereof is substantially equal to the total length of the side wall and arch of the predetermined tunnel T, the volume in the tunnel can be effectively used.

Then, an injection hole for air or the like is opened at the end.

(C) Wall Sheet The wall sheet S is a water-impermeable sheet having a rectangular shape.

As for the wall sheet S, the sheet located on the inner peripheral surface of the continuous structure A is formed as the lining sheet S1, and the sheet located on the outer peripheral surface of the continuous structure A is formed as the outer covering sheet S2.

(D) Formation of continuous structure An example of the method for forming the continuous structure A will be described. For example, the tubes 1 are arranged on the outer sheet S2 at a predetermined interval in parallel with each other, and each tube 1 A part of the peripheral surface of the tube 1 is fixed to the outer sheet S2 using an adhesive, and the opposite side of each tube 1 fixed to the outer sheet S2 is covered with the inner sheet S1. If the portion is fixed to the lining sheet S1 with an adhesive or the like, the flexible continuous structure A can be formed.

The continuous structure A formed as described above is not actually integrally formed over its entire length, but the continuous structure a formed for every arbitrary number of tubes is connected to form a continuous structure of a predetermined length. Form body A.

The connection of each continuum a is such that, for example, a method of adhering an end side parallel to the tube 1 of the continuum a as an adhering piece a1 or a method of using an airtight fastener, the connecting portion maintains airtightness. Any method will do.

Next, a method of constructing an underground warehouse or the like will be described.

A tube of approximately the same length as the inside diameter of the tunnel to be installed
The required number of continuous bodies a having a predetermined size are prepared in advance in a factory or the like by the above method by using the wall sheet S and

The above continuum a is loaded into a predetermined tunnel, and each continua a
To connect.

The continuous body a can be carried in by folding it in a small size before injecting the air and the curable fluid into the tube 1.

That is, it is much easier than carrying in a lot of equipment and materials as in the case of constructing a concrete structure in a tunnel.

After connecting the continuous body a to form a predetermined continuous structure A,
The filler J and air are injected into the continuous structure A by partitioning with the tube 1 so as not to mix.

As a result, a semi-cylindrical continuous structure A, which is similar to the cross-sectional shape of the tunnel and is almost filled in the tunnel interior, is formed.

As the filling material J to be injected, a curable fluid such as urethane foam, concrete foam, or lightweight concrete is used.

In short, any material can be used as long as it has good heat insulation performance and can be used as a reinforcing member.

By hardening the filler J, the continuous structure A is strongly reinforced, and even if air leaks out, the entire shape of the continuous structure A does not change.

Further, as shown in FIG. 2, the method of injecting the filler J and the air is such that the filler J is alternately or at arbitrary intervals in the tube 1.
And air are injected into the space formed between the group of tubes 1 and both sheets S1 and S2, and only air or the filler J
If only inject.

In addition, as shown in FIG. 3, the case where all the air is injected into the tube 1 and the filler J is all injected into the space around the tube 1.

Further, on the contrary, there may be a case where the filling material J is injected into the tube 1 and air is injected into the space around the tube 1.

<Effects of the Invention> Since the present invention is as described above, the following excellent effects can be obtained.

(B) Air and a curable fluid are injected into a continuous structure consisting of a tube group and a water impermeable sheet to start up the continuous structure to build a structure.

Therefore, the construction is easy, and the structure can be firmly held by the hardened curable fluid.

Therefore, it can be applied to a structure requiring rigidity such as a warehouse.

(B) Since the continuous structure is covered with a double-walled sheet that is lined inside and outside, it is excellent in waterproofness and can prevent an increase in humidity in the warehouse.

(C) Due to the heat insulating effect of the air in the tube and the filler having a heat insulating property, it is possible to suppress the internal temperature decrease and thus prevent dew condensation.

(D) Since the building in the tunnel is of a membrane structure, it can be carried in easily and quickly for construction,
Further, the structure to be constructed can be filled up in the air in a predetermined tunnel, and the volume of the warehouse can be increased.

(E) There is nothing like a concrete structure that scatters when an accident occurs, so safety is high.
