摘要： A piping travelling apparatus having a plurality of continuous treads (15) driven by motors (10) through transmission gearing (11). The continuous treads are mounted to a frame (20) and spaced apart a predetermined distance peripherally of the inner wall surface of the piping (3). At least one of the continuous treads is kept in contact with the inner wall surface of the piping no matter what the posture of the apparatus may be, so that the apparatus can travel without any trouble even if its posture undergoes a change when it moves along elevations and depressions on the inner wall surface of the piping or negotiates the boundary between different levels of the inner wall surface or bends of the piping. The apparatus enables a travel through piping of relatively small diameter having vertical or steeply slanted pipes to be made without any trouble.

摘要： PURPOSE:To prevent underground water from penetrating into the bottom of an underground tank by providing a freezing pipe near the contact area between a skeleton concrete of the underground tank and the ground to freeze the surrounding concrete and ground by circulating nonfreezing low temperature fluid. CONSTITUTION:A freezing pipe 11 is laid near the contact area between a bottom plate 7 of an underground tank of concrete and the ground 5 comprising a water-impermeable layer along the circumference of the plate 7. Next, a nonfreezing low temperature fluid such as a water solution of ethylene glycol is circulated through the pipe 11 to freeze the concrete and ground around the pipe 11 to obtain a frozen part 13, thus preventing the underground water from penetrating into the bottom of the tank. As a result, water stopping can be surely achieved. And since the concrete and ground having large specific heat is located deep in the ground and frozen, once the concrete and ground have been frozen, a large amount of heat is not required to keep the frozed state. Particularly in the case that, as is the case of an LNG underground tank, the ground around the tank has been cooled by the cold load of LNG, required amount of heat is small and hence a refrigerator 15 of small capacity can be used.

摘要： PURPOSE:To make it possible to make a tank roof on the spot and place the roof on the top of an underground tank main body as it is while keeping the shape of the roof to be flat and the height to be approximately 1-2m by a method wherein beam members made of reinforced concrete are arranged into a grille shape, and at the same time, reinforced concrete plates are placed between the beam members to constitute a flat shaped self-standing roof, and this roof is attached to an underground tank. CONSTITUTION:For a roof 2, roof beams 3 are assembled into a grille shape using a reinforced concrete material (or prestressed concrete material), and between the roof beams 3, reinforced concrete plates 4 are installed. In the case of a normal underground tank, the diameter of the roof 2 reaches 60-70m, and therefore, the roof 2 is manufactured at a place close to an underground tank main body 1. For this reason, in the place of the reinforced concrete plate 4, raw concrete may be poured between the roof beams 3 on the spot, to manufacture the roof 2. The roof 2 manufactured in such a manner is moved and placed on the top of the underground tank main body 1 using a moving device, to complete the underground tank.
