Parking lot (garage) The main function of the parking lot (garage) is to store and park vehicles. According to its storage conditions, it can be divided into four categories: warm garage, cold garage, carport and open-air parking lot; according to its space utilization, it can be divided into single-storey parking lot and multi-storey parking lot. Multi-storey parking lots usually need to be equipped for vehicles. Ramps, rotating lanes, or elevators where vertical displacement occurs. In the parking lot (garage), in accordance with the technological process after the vehicle returns to the site, relevant facilities such as cleaning, routine maintenance, refueling and inspection, as well as necessary lighting, sanitation and fire-fighting facilities should be set up. 2. Freight station. Car freight station is sometimes called bus station or auto yard. Its main task is to complete cargo transportation production operations safely, conveniently and in time. In addition to the production and living rooms, the layout of the freight station is mainly the setting of parking lots. Large bus stations also have maintenance yards, repair shops and gas stations, and small stations have garages and first- and second-level maintenance stations. 3. Highway Highway is a linear engineering structure. It mainly bears the repeated action of automobile load and the long-term influence of various natural factors. Therefore, the requirements for highways must not only have gentle longitudinal slopes and smooth lines, but also have strong and reliable artificial structures, stable and solid roadbeds, smooth and non-slip roads, and other necessary protective engineering and auxiliary equipment. The basic components of the highway include: roadbed, pavement, bridges, culverts, tunnels, protection works (guardrails, retaining walls, foot protection), drainage equipment (side ditch, intercepting ditch, blind ditch, water drop, rapid trough, ferry (Throwing) water troughs, water crossing roads, seepage embankments), special structures in mountainous areas (banshan bridges, embankments, Mingdongs). In addition, in order to adapt to traffic, traffic signs, gas stations, road houses, communication facilities, affiliated factories and green planting are also set up. The commonly used roads in our country mainly include gravel pavement, gravel graded pavement, reinforced soil pavement, asphalt surface treatment pavement, asphalt pavement, asphalt gravel pavement, asphalt concrete pavement and cement concrete pavement. Different surface layer types are suitable for different grades of pavement. 4. Bridges and tunnels Bridges and tunnels are short for bridges, culverts and tunnels. They are all buildings built for vehicles to pass through natural obstacles (river, mountain) or cross other three-dimensional traffic lines. The common point of bridges and culverts is that vehicles run on them, mainly used to cross rivers. Generally, the single span of bridges is larger than culverts, and the total length is longer than culverts. According to the relevant regulations on highways, any single-hole standard span is less than 5m or the total length of the multi-hole span is less than 8m is a culvert; the bridge is larger than the above-mentioned regulations. The tunnel is similar to the culvert, but the tunnel is mainly used to cross hills, and the vehicle runs in the tunnel.
