However, such conventional aeration methods can be implemented in the case of storage tanks where holes can be made in the side walls of the storage tank, but they cannot be used in underground storage tanks where holes cannot be made in the side walls of the storage tank.
This was not possible for storage tanks with concrete outer walls.

In a storage tank a formed by a concrete outer wall b with
A hoisting rope f is attached to the outer periphery of the hoisting machine (not shown) via a rope sheave g temporarily installed on the outer periphery support e of the roof installed at the top of the side wall of the concrete outer wall b. The rope f was wound up and the roof c was lifted up to the outer peripheral support part e of the roof. Also, a method was adopted in which a rod was used in place of the rope f, and a hydraulic jack was used in place of the hoisting machine, but both methods required temporary installation of the rope sheave g and rod, and the use of the hoisting machine and hydraulic jack. There was a problem that the cost and construction period increased due to usage.

The present invention was invented to effectively solve the problems of the prior art, and is an above-ground storage tank that does not have a construction opening for introducing air into the storage tank from the side wall, which is impossible with the conventional air raising method. The purpose of the present invention is to provide a method for air raising the roof of an underground storage tank.

In order to achieve the above object, the method for constructing an air raising type storage tank roof of the present invention includes disposing an air blower on the upper part of a storage tank roof having an opening, communicating the outlet of the air blower with the opening, and connecting the air blower with the opening. Air is blown below the roof, the storage tank roof with a seal to prevent air leakage is floated on the side of the roof, and the roof that has floated to the top is supported on the outer periphery of the roof installed on the side walls. It is characterized by being fixed to the part.
以下、図面に基づいて本発明のエアレイジング

る。 A concrete outer wall 2 is cast underground, and a membrane 8 is attached to the inner surface to form a storage tank 1. A blower 4 for feeding air is installed on the top of a roof 3 that is assembled at the inner bottom of the storage tank 1 and has an opening 6 for feeding air. Connect with 5. Furthermore, a sealing material 7 is attached to the side of the roof 3 to prevent air leakage.

As explained above, according to the method for constructing an air-raising type storage tank roof of the present invention, a blower is installed on the upper part of the roof and air is sent to the lower part of the roof to perform air raising. Of course, even above-ground storage tanks without construction openings on the side walls,
The roof assembled at the inner bottom of the storage tank can be floated with air, making it possible to eliminate the need for a roof lifting device. In addition, since the distance from the blower to the roof is shorter, the length of the piping can be shortened, and losses within the piping can also be reduced, resulting in an excellent effect of reducing energy consumption.
