The corresponding specification of the return road section is to meet the requirement of one-time rotation of one vehicle. The size of the vertical parking space is standard: width 2.5m, length equal to or greater than 5m, with the general standard being 2.5m by 5.3m being the optimum standard parking space size. The size standard of the inclined parking space is as follows: the width is 2.8 meters, the length of the oblique line reaches 6 meters, and the vertical distance between the two oblique lines is still kept at the standard of 2.5 meters. The underground parking lot mainly used for parking small vehicles adopts the parking space size of 2.5-2.7 multiplied by 5-6 meters, the width of a single lane rotary lane is not less than 3.5 meters, and the width of a double lane is not less than 5 meters.
When the underground garage is designed, the requirements of length, width and road are met, and the design requirement of at least 2.2 meters of height is also met. However, the current engineering related personnel generally draw two-dimensional engineering drawings, and the defects are as follows: 1. the three-dimensional data of the garage can not be intuitively known, the air height condition is not clear, and the requirement that the garage needs to meet the height of the vehicle can not be met. 2. The two-dimensional engineering drawing is a static drawing, and the design defect of the vehicle in dynamic operation in the garage cannot be predicted.

The three-dimensional structure can not only embody the garage size height directly perceived, can also establish out door frame, crossbeam, stand, the arrangement of water and electricity pipe network in the garage.
Furthermore, in the fourth step, according to the BIM garage data map, the height of the passageway and the lane space between the floors is verified, the passageway and the lane space meeting the parking space height requirement are connected with the lane, the parking spaces are updated, the number of the parking spaces before and after modification is compared, and the optimal scheme is determined.
Furthermore, in the fifth step, according to the BIM garage data map, according to the standard width of the lane and the standard requirements of the parking spaces, a blank area which is not included in the lane and the parking spaces is marked, the area of the blank area is calculated, when the area of the blank area is larger than the area of one parking space but the length and the width are not suitable for arranging the parking spaces, the direction of the parking space close to the blank area is changed, whether the number of the parking spaces can be increased or not is compared, and a preferred scheme is determined.
Furthermore, in the sixth step, according to the BIM garage data diagram, the driving, turning, intersection and parking of the BIM vehicle are simulated on the lane, when the BIM vehicle cannot meet the requirements of driving, turning and intersection, the road marking is modified, when the BIM vehicle cannot normally park and enter the garage, the direction of the parking space is modified, after the direction of the parking space is modified, the BIM vehicle still cannot park and enter the garage, and when the BIM vehicle cannot additionally connect the road, the parking space is deleted, the number of the parking spaces of the whole garage is determined, and the parking space arrangement diagram of the whole underground garage is drawn.
The BIM vehicle can be designed in a garage by utilizing the modeling function of the BIM system and the fuzor software to simulate the vehicle running, simulate the running in a road and simulate the vehicle entering and leaving the garage. And completing dynamic vehicle library simulation and effect pre-judgment.
Furthermore, according to the arrangement diagram of the parking spaces of the whole underground garage, the arrangement diagram of the sewer and the inspection well cover of the whole underground garage is drawn by combining BIM, the area overlapped with the parking spaces is marked, and the sewer and the inspection well cover in the area are marked for reinforcement.
In the design of reality garage, want to avoid sewer and inspection shaft lid as far as possible, but this interests that can sacrifice the owner by a wide margin, so, when the design side carries out the parking stall planning, neglected sewer and inspection shaft lid that do not have the bearing design completely, the garage design can be intervened in advance to the BIM unit, and the water course and the inspection shaft lid in key region can obtain the safety guarantee in advance, have eliminated the potential safety hazard for the later stage is used.
The invention has the beneficial effects that: the three-dimensional data and the air height condition of the garage can be intuitively known, and the requirement on the vehicle height of the garage is effectively met. And the dynamic design can predict the design defects of the vehicle in the dynamic operation in the garage and eliminate the potential safety hazard when the garage is used. The parking space arrangement is optimized, and the quality and the quantity of the parking spaces are improved.
