It is a wallpaper photograph of Kurobe Dam, autumnal leaves, and sightseeing water-drainage
Kurobe Dam at the time of autumnal leaves was visited. The Ushiro Tateyama mountain range covered snow and became white, the autumnal leaves of the outskirts of Kurobe Dam were carried out, and they were brilliant scenery. Kurobe Dam is an arch type dome shape dam called the fourth dam (Kuroyon dam) of alias Kurobe. This name is so called from supplying power generation city water to the fourth plant of the Kansai Electric Power Kurobe river. It is proud of 186m in height of the No.1 bank of Japan as an arch type concrete dam, and is a dam famous for the difficulty construction seen rarely. Moreover, the length of a bank is no less than 492m, and, as for what, about 200 million cubic meters, and area, 349ha also has the total pondage. It is said that it can also be 160 cups if this total pondage is converted into what and TOKYO DOME. Start will be in 1956 (Showa 31) and completion of having been built although it was the dam which Kurobe Dam dammed up the water of the Kurobe river and was made is 1963 (Showa 38). It completed at last in the end of the carpenter of taking seven years. It is because there was the purpose that the serious electric power shortage after the end of the war had to be canceled as to why such a carpenter thing is needed. It is the point how having become a problem most on the occasion of the Kurobe Dam construction carries a construction material. It is a canyon where the mountains in the 2500m-3000m class north Alps, such as the Tateyama mountain range and a Ushiro Tateyama mountain range, stand in a row back, and is the beginning of the carpenter who builds the dam of a scale like this [ how ] or from whom it has become a part of Tateyama Kurobe Alpine route of the future. The Omachi tunnel which falls out from Shinano-Oomachi to Kurobe Dam by the present Alpine route is made in order to carry a construction material also as a basis. Although the tunnel which amounts to 5.4km directly under [ Mt. Akazawa (altitude of 2687m) ] a Ushiro Tateyama mountain range for this Omachi route construction is dug, the large crush zone which a lot of cold water spouts from the Omachi side at the point of the 2.6km hit where a tunnel falls out directly under the Mt. Akazawa summit of the mountain exactly in this case is encountered,Since many victims were sacrificed, construction is obliged to the middle. Although opening of traffic was also considered to be despair, the civil engineering of that time newest and the technical essences were collected, an 80m crush-zone breakthrough took no less than seven months, and opening of traffic of the Omachi tunnel was reached at last in May, Showa 33. However, since opening of traffic of the Omachi tunnel took time too much in one side, it is the period till then,Materials carrying in is the Tateyama Ichinokoshi peak with an altitude of 2700m. It is said that the load over 50kg is carried on the back, and it exceeds by human power, or there were difficulties [ say / rising and falling a steep incline by bulldozer ] which are desperate and the method of a way does not have, either. Moreover, the temporary waterway was dug using materials and the machine which it was or it has dammed up and built water how, but arrived the dam of a scale like this at the spot across the mountain before tunnel opening of traffic, water was poured there, and dam construction was performed. Moreover, in order to support dam both sides, the structure which supports water pressure by a base rock directly is needed on the dam of a scale like this. Since the arch type dome shape dam can distribute water pressure, compared with a gravity dam, it can make comparatively thinly, but it cannot finish supporting only by it. Kurobe Dam completed at last also serves as a vestibule leading to the outside of Omachi of the Tateyama Kurobe Alpine route now. Sightseeing water-drainage of the Osako power which blows off no less than 10 cubic meters/s can be seen till June 26 to October 15. If fate will avoid the best time to see of the autumnal leaves around Kurobe Dam or the Kurobe lake in mid-October, three-step autumnal leaves will also be seen.
