Of pay enough name . K. Device device D10-KjKS-1, KS-: called j capacity lo. Line Line 10 Road, 0. 030, ooo ~ mlip, 000 (KS-1.1z, 400 (KS-2 uses l city exchange. City exchange and outside the city and the city's transformation machine machine I used heavy machine j l replacement (2) power supply telephone exchange's daily electricity supply and installation of commercial batteries with power supply. When a power failure, set the generator can automatically replace the power supply bureau, or by battery. To prevent power outages, to foolproof increase the capacity of the battery or with a portable generator and rectifier. (3) Wireless telephone cable disruption due to disasters caused by, the need to use a wireless telephone. Therefore, as a one-off measures, the use of wireless telephones. wireless phone varied, from small capacity to a radio relay stations are used in wireless phones. For example, long-distance mobile wireless phone use 'rY-4p, 6P, short-range wireless mobile phone with' I and so on. The former suitable for microwave transmission lines used on the relay stood in relief, which is suitable for coaxial transmission lines, microwave transmission lines, etc. to use in the rescue. TZ-403 type mobile radio telephone, TZ-68-based mobile wireless phone for transmission lines under centralized bureau used in the rescue. (4) the use of satellite wide area from the visible region of Xin, the line made of the rapidity, TV in the trunk to a temporary phone line, with the use of elasticity, in Disaster is the most effective system. (5) emergency repair job on the line cable, the most time is the connecting cable wire used for connecting devices can easily continue operations. in the restoration work, lightweight fiber-optic cable easy to handle,[link widoczny dla zalogowanych], use the wide range of Si can be used in wide-area disasters and high-speed line repair. (Zhang Daming trial) * Technology News Japan into the world's largest wind tunnel testing facilities, according to the Journal Japan's bridge-building with the world record plane, under construction in the Tatara Bridge is a cable-stayed bridge main span of 890m, and its record over the span of the French to keep the world record Luo Mandi bridge (main span 856m), in one fell swoop cable-stayed bridge in the world who the world record. I987 opened to traffic in April like the South prepared Seto Bridge, is a main span of 1100m of the dual-rail suspension bridge, although the dual-rail suspension bridge to the world record,[link widoczny dla zalogowanych], but the span of more than pod Kwok-hang, not Bill Bridge (main span of 1410m), this, Japan has the design and construction of a bridge spanning the Straits I990m - Akashi Kaikyo Bridge, the span set a world record. In the Akashi Kaikyo Bridge design, construction process, using a number of new Zhu surgery, one of which is the use of advanced air leak test equipment. Since suspension is a very soft structure, so wind-resistant design that is the question, for which Soil Research Institute Ministry of Construction of Japan built the technical world's largest wind tunnel test facilities, and the Akashi Kaikyo Bridge were the overall model test of the wind tunnel tests of building size t length 75.4 × width 53x high 17.5 ~ 19. 5m, for I measured the size of some long-30x W 4l × providers 4m, wind speed range of 0.5 ~ 12.0m/see, into the fan 1.8m × 36 units. The wind-driven wind heir width 41m facility in Tokyo, Japan University of 16m wide compared to the existing significant increase, and the width of the world's largest person (20m) twice. Akashi Kaikyo Bridge, the proportion of test model is a real bridge I/100. test, first remove the beam part of the ,[link widoczny dla zalogowanych], Spring support, according to two-dimensional loading test, and then to evaluate the structural characteristics and the complete three-dimensional dynamic characteristics of the overall model base test. Accordingly, the bridge's wind resistance for more rigorous checking. in the development of test plans, In order to reproduce the high-precision structure of the Akashi Kaikyo Bridge, the aerodynamic properties, Taiwan reasonable model for many aspects than the reverse, the results, select the 1 / 100 scale management units as a basis for determining the wind tunnel equipment specifications. the construction of the wind one of the purposes is to verify drain the world's largest bridge span of the Akashi Strait, the wind resistance dip too, so seek the best economic design of the bridge. June 1991, to 1 / 100 side of the barrier of the bridge than the overall model was wind test, test the left from the bridge's wind resistance to 6m/sec built right into the wind,[link widoczny dla zalogowanych], measured across the largest deformation (bending to the right) about 30ram, the test results and accounting standard results. It can be seen, the bridge can withstand strong typhoons 60m/sec. (Chen Kaili Liu Kuide) 30
