Shenzhen Longcheng Special Service Fire Station, situated at the intersection of Qingshui Road and Yishan Road, Longcheng Street, Longgang District, Shenzhen, is the first special service fire station built in line with the “standardized design of Shenzhen New Fire Station” in Longgang District. The ground is square in shape, but the surrounding environment of the base is complex. The cultural and sports center on the west side has noise interference to the fire station. There are high voltage lines on the northeast side and planned refined oil and high-pressure natural gas facilities on the north side. It is a high-risk zone on the city boundary, posing major security risks to the city and buildings.
Therefore, the building is constructed on the south side, leaving the site on the north side, so as to avoid the refined oil and high-pressure natural gas facilities as well as high-voltage lines, and make room for gardens, the “breathing space” as far as possible. In the meantime, fast response from the city street, just like the “winged general” in the Longcheng Special Service Fire Station, guards the safety of one region.
The project is located in Longcheng Street, Longgang District, Shenzhen, with a square shape. Yuhu Shanpan high-rise residential community is on south side of the site, the factory on the east side, and cultural and sports center on the west side, adjacent to Shenzhen Outer Ring Highway on the north side.
Covering a construction area of 5187.09㎡, it is a special service fire station, which can accommodate 12 fire trucks, with the floor area ratio of 1.06. The total construction area is 6914.5㎡, of which the capacity building area is 5520㎡, and non-capacity building area is 1394.5㎡, including a 4-story fire service building, an 8-story training tower and a basement. Located at the junction of suburban areas, it is a typical “centralized” fire station that connects the city and green space.
The cultural and sports center on the west side of the land of Longcheng Special Service Fire Station has noise interference to the fire station, and high voltage lines on the northeast side, as well as the planned refined oil and high-pressure natural gas facilities on the north side have a significant impact on the architectural design. Therefore, the building is designed to be constructed on the south side and the site on the north side, avoiding refined oil, high-pressure natural gas facilities and high voltage lines.
In order to meet the rapid response of fire cases within one minute, “inner courtyard” exit of the traditional fire station is changed to the “drive-out by street” of the new fire station, directly facing the Yishan Road on the south side. The exit of the fire garage is 59.4m wide, and the distance from the roadside is 15m, leaving an open “breathing space” for the north side.
The south side of the project land is adjacent to Yishan Road, where the main entrance is set up, including the exit of the fire garage and the exit square, for the firefighters to go in and out. The southwest side is the main entrance for firefighters and visitors. The secondary entrance on the east side is the logistics and basement entrance. The fire training field, running track and basketball court are on the north side, leaving gardens, the “breathing space” as large as possible.
Due to the shortage of land for the project, setback line could not be made in accordance with the requirements of Shenzhen local regulations. After communicating with the Planning Bureau for many times to demonstrate the setback line, more reasonable setback lines were finally proposed: moving 1.8m on the east side, 15.0m on the south side, 2.2m on the west side and 50m on the north side, so as to ensure scientific and reasonable fire station and sports ground in the tense land.
Longcheng Special Service Fire Station adopts the “centralized” layout, consisting of a 4-storey business building with the height of 17.7m and an 8-storey training tower with the height of 32.75m. There is various interference around the land, so it is necessary to rationally arrange the station, the dispatch square and the training ground, and properly solve the contradiction between the project and the surrounding environment.
Fire trucks directly drive out from the street, and 12 fire trucks can park on first floor, greatly improving the efficiency of the police. The main access is on south side of the site, through which firefighters and visitors enter the fire station. The open area is located on the ground floor and mezzanine. The fire garage faces the vehicle square. The hall, the restaurant, the equipment warehouse, etc., are on the first floor, the standby room, the cadre standby room, and the squadron office are on second floor. The washing room and the shower room are on the north side, and the business room and the auxiliary room are on the third and fourth floor, which mainly function as emergency rescue warehouses and equipment rooms, and the basement entrance is in the northeast corner of the building.In addition, hanging gardens are set up in many parts of the building to enrich the lives of firefighters.
This project adopts green building and sponge city technology, absorbs and accumulates rainwater by rooftop orchards, sunken green spaces and so forth, effectively controlling rainwater runoff in the site.
On the south side of the Longcheng Special Service Fire Station is the main entrance for firefighters and visitors to enter the fire station. When visiting on weekends and holidays, the public can reach the corridor on second floor through elevator on the first floor, visit the fire garage and the green orchard on the roof of the garage, and overlook the training ground. When booking a visit, the open area can be visited through a complete streamline line, and the connection between the closed area and the open area is equipped with a management port, so that it does not affect the daily training and attendance of firefighters.
The design is optimized and upgraded on the basis of “Shenzhen new fire station standardized design”, adds personalized elements, and adopts a more modern and simple design method. Through the contrast of white, grey, wood and other materials, as well as the combination of the volume and the folding plate, it clearly expresses the corresponding relationship between the function and form of the building in the intensive and compact form. At the same time, vertical grille, facade holes, wooden boxes, local aerial, hanging garden and so forth are used to adapt to the hot and rainy climate of Lingnan. The solemn and dignified architectural form also shows the solemn and stable “security guard” image of Longcheng Fire Station.
