【正文】 d rises, restored to the throne again. Form a plete set and install the intellectual administrative system of the parking area after installing the largescale underground parking of the threedimensional garage, go on one on duty to manage hour through professional staff member of technical training. Third, threedimensional garage build cost lower than the traditional parking area greatly. It is reported, the occupation of land and building cost in the traditional pa rking area is quite high. Do not generally get on very well, ordinary each occupation of land in the parking stall, about 15 square meters, the floor space of each parking stall of XIV underground parking is above 25 square meters at least on the ground. If use the threedimensional garage parking, can park one group and 8 parking stalls of threedimensional garage parkings on the vacant lot of 30 square meters, the average floor space of each parking stall is less than 4 square meters. In respect to building cost, the house property developer of the district builds an underground parking stall to need to invest 60,00080,000 yuan at present, the construction cost of some topgrade underground parking stalls of office building is up to more than ten ten thousand yuan especially. If install the threedimensional garage, is it increase parking stall is can cost stand thin to reach 50,00060,000 yuan each construction of parking stall to try one39。 And daily in operation that here work charging, security personnel, staff of maintaining etc. : have nearly 20 people, personnel of one day salary expenditure is more than 1000 yuan。 The investor of threedimensional garage should innovate actively too, improve the engineering level and management level, change the idea of managing. Believe in the near future, the development of the threedimensional garage of our country will be like developed country too, the traffic and urban environment of the city can get very great improvement. List of references QiJun L threedimensional garage39。s road..In addition, citizens still think, though the threedimensional garage saves the space, go to the ground all over the world, worries the pet car is hung up high, or deepen underground oneself. It is that the threedimensional garage develop the winding basic reason at abovementioned two o39。 Improve of the threedimensional garage The highspeed development of national economy and urbanization level of our country are being accelerated constantly, make the contradiction congested in traffic of the city conspicuous day by day. The increasing constantly of the vehicle, facilities of urban road can not catch up with the paces of economic development, has caused the blocking seriously of dynamic traffic, park whom place set up unreasonable, appear parking dish serious at the same time, take up the green land of inhabited region, cause the confused phenomenon of static traffic, thus aggravated the traffic jam further, have destroyed the living environment of the city and urban image. The relation of dynamic traffic and static traffic has formed the vicious circle. According to statistics, China is by the end of 2020, the recoverable amount of motor vehicle has already been up to more than 96,490,000, according to the present growth rate, by 2020, the recoverable amount of automobile of our country will reach 30 million, among them car recoverable amount will be up to 1000 ten thousand. However, the recoverable amount of the urban motor vehicle of our country is probably 5 pared with the parking stall at present: 1, that is to say the satisfication rate of the parking stall is about 20%. The parking stall is insufficient seriously, cause motor vehicle park, park phenomenon to be day by day serious dish illegally, Shanghai center account for dish is it is it park 64% of vehicle always to account for to park. Automobile recoverable amount of 1,600,000 calculate at present according to Shanghai, ideal parking stall should have 208 ten thousand, but only there are 30,000 parking stalls in the open social garage of Shanghai at present, this causes a lot of vehicles to be homeless. : By the look of experience of the international urban construction, should guarantee the traffic does not have stopping up, not merely take satisfied 100% of the basic parking stalls, it still can take satisfied 20% XIII of the public parking stalls. Unless in recent years for on the every year when it increase by car newly in the 2 million vehicle about, it in a ratio of on the 1:1 counting according to parking stall and car. : calculate 2, need to increase by 2,900,000 parking stalls newly every year, could meet parking stall39。 In addition, the garage building and equipment gross investment are 27 million yuan, calculate with useful life 20, depreciation of every day should 3700, so thick to is it e to calculate while being thick, the business ine XI could break even in 5000 yuan at least this threedimensional every day such as garage . The actual conditions are, opening the door will stick 2020 yuan each day each time, 60,000 yuan of loss in one month. The operater39。s technical force exists, lack such questions as the ability to develop independently,etc., : guarantee that the dependability, security, durability of the products can39。經營商的投資得不到相應的回報，極大的打擊了他們的投資熱情，立體車庫的經營更是陷入困境，為收回成本，只能通過提高立體車庫停車的價位，然而，越是價位高，越是無人問津 ，車位閑置的狀況也越來越嚴重，由此便形成了惡性循環(huán)，嚴重的阻礙了立體車庫的順利發(fā)展。 其次，市民長期的意識也很難在短時間內改變，雖然有明文禁止路邊空地停車，但 VI 在大街小巷仍可隨處見到違規(guī)停車的。如上海九江路浙江路口的八達停車庫，它是全國最早設立的立體停車庫之一，但 1994 年建成至今，成本仍未收回，平時停車量僅 為 15% 左右，不得已只好將停車費由 15 元降至 10 元。如果使用立體停車庫，在 30 平方米的空地上就可以停放一組 8 車位立體停車庫，平均每個車位占地面積不到 4 平方米。例如，在空間有限 V 的居民小區(qū)地面上最適合使用“垂直循環(huán)”式立體車庫。停車位嚴重不足，造成機動車非法停放、占道停放現(xiàn)象日益嚴重，上海市中心占道停放占總停放車輛的64% 。 III 畢 業(yè) 設 計 題目： 立體車庫傳動系統(tǒng)設計 學 生：
