【正文】 stalls, it still can take satisfied 20% VIII 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。s demands. of the threedimensional garage With the rapid development of Shanghai, the settlement of the difficult problem of parking of Shanghai has already reached the very urgent stage. In the city center where every inch of land is precious, especially the area which such vehicles as the hotel, market, shopping center location,etc. : concentrate, can only develop to the sky, to underground, so has built and already to a great deal of threedimensional garage parkings reached the essential stage, at the same time there are many advantages too in the threedimensional garage parking.. First, economize the space. Generally speaking, its floor space is about 1/2/25 of the level parking area, machinery type Threedimensional The garage can both be installed with the ground underground, the greatest advantage can fully utilize the small area to develop to the high altitude, try one39。s best to store more vehicles, the place that the land resource in short supply, the vehicle is big in capacity to park in the way bestly. For example, are most suitable for using vertical circulation on the limited residential quarter ground on the space Threedimensional garage of the type. 8 storeys of every groups of this kind of garage, that is to say, only parked the threedimensional garage built up on the area of a car and park 8 cars originally. Second, automation is controlled, easy to use. The threedimensional automatic degree of garage parking is very high, can hoist or lower the rotatory type, for example, district residents e off duty back and park, so long as according to the number that the brasswind instrument is corresponding with the parking stall, this parking stall will be rotated and landed to the ground, after the car owner parks the good vehicle, and then according to the number, the parking stall circles round and 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 parking 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 IX 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。s best in a situation that the area of space does not change. Fourth, it is safe and reliable and beautifying the environment. Allocate the automatic detection system, various kinds of safe anizations, autoalarm, firefighting system and other strick precautions facility. The automobile will not damage, loses. Suit measures to local conditions, utilize fragmentary vacant lot, shape beautiful garage beyond mix, beautify the urban environment. in the reality of threedimensional garage There is a very great advantage in various fields in the threedimensional garage, but the parking situation of the threedimensional garage of what Shanghai have now still allows of no optimist, developing a lot of twists of the threedimensional garage. If eight of the crossings of Zhejiang of road of Jiujiang of Shanghai reaches the garage parking, it is one of the threedimensional garage parkings set up first in the whole country, but built up so far in 1994, the cost is still unrecovered, the parking amount is only about 15% at ordinary times, it have to be dropped parking fee to from 15 yuan 10 yuan that there is no alternative. Compared with the situation that eight ones that reach the garage parking are desolate, Nanjing road surface by the pedestrian street is it is it it orders to be but as crowded as a market to charge to park. treated coldly in threedimensional garage Do not appear uglily: Put the car to calculate by the hour in the threedimensional garage parking, general working clan should stop to park for one day for last nine hours, want 90 yuan. And the parking area on the road surface charge according to it or in due order, ten yuan each time. Under this situation, has already made advantage of the threedimensional garage more, under the enticement of the money, it should know the car too what course should follow. Analysing the reason, what the threedimensional garage is treated coldly is mainly because of the following several points. First of all, the threedimensional garage is still the new industry in our country, it is X weak that enterprise39。s technical force exists, lack such questions as the ability to develop independently,etc., : guarantee that the depe
