Layout is carried out according to the medical procedures of infectious diseases, and the basic divisions are divided into clean areas, restricted areas (semi-clean areas), and isolation areas (semi-polluted areas and polluted areas). Buffer rooms and isolation measures are set up between the corresponding areas.
patients enter the isolation observation ward through the patient corridor for isolation observation. Medical staff set up sanitary entrance rooms and sanitary entrance rooms from the entrances and exits of the polluted area from the cleaning area. Sanitation is divided into inlet and outlet streamlines, and between men and women.
The specific entry process is: cleaning area enters the contaminated area through one dressing (wear work clothes), second dressing (wear protective equipment, wear protective supplies), and buffer zone; the return process is: take off protective clothing, buffer transition room (take off protective clothing and other protective supplies), and return to the cleaning area. After the pollution protection supplies in the undressing buffered area of the observation ward are packaged, they are stored together with the waste generated in the observation ward in the garbage temporary storage room in the observation ward area, and the medical waste from the disposal room is packaged and shipped out directly.
The bathrooms and wash basins used by patients are all set inside a single "ward cabin". Each ward has about 1 finished toilet, 1 shower room and 1 wash basin, respectively, and considering the needs of the elderly, the weak, the sick and the disabled, some finished toilets and shower rooms are equipped with handrails.

structural design
Decheng District Fangcai Hospital is a floor-level prefabricated light steel mechanism system , and the structural design has a service life of 5 years . The above-ground structure adopts a box structure, and the foundation uses raft foundation . The project has a north-south length of 153m and an east-west length of 103m, making it an ultra-long structure.
This project is a temporary disaster prevention building for the response to the new coronavirus pneumonia . The construction period is tight, the time is short and the tasks are heavy. In order to ensure the smooth delivery of the project on schedule, the construction site will directly lay the 250mm gravel cushion layer after the current site is leveled and compacted as the foundation of the building.
Because this project is located in Dezhou, Shandong, according to the experience of the surrounding project, the soil bearing capacity of the site is poor. In order to reduce the impact of uneven site and consider the construction period requirements, and reduce the workload of on-site steel bar processing and support molds, the foundation adopts a 250mm thick raft foundation, and a double-layer bidirectional steel bar mesh is installed, without a post-pouring strip, raft uses C30 early-strength fast hard concrete, and at the same time, the addition of expansion agent, low-hydration hot cement, and strict control of the water-cement ratio and other measures to reduce raft cracking. The superstructure adopts a modular box structure, with a standard module size of 3m×6m×3m, and is assembled on site after the strength of the foundation concrete meets the installation and construction requirements. The box structure and the foundation are connected through embedded parts that are pre-embedded in advance.
water supply and drainage design

A backflow preventer is installed before the water supply system in the polluted area is connected; the water supply system in the semi-polluted area and the safety area adopts the municipal direct supply method. The system uses standardized, integrated and highly assembled equipment, pipeline systems and accessories; the equipment adopts integrated bathrooms, integrated shower rooms and other facilities, and reserves a group of extended interfaces and space; the pipeline systems and accessories are preferred to use pipes that are easy to install and disassemble and reusable.
wash basin uses a small volumetric electric water heater (Xiaochubao) to prepare domestic water. The concentrated shower hot water is prepared by an electric water heater.
separate drinking water utensils are set up in the contaminated area and in the cleaning area.
Install purification and sterilization devices at the outlet of the drainage vent pipe of the drainage system in the contaminated area for processing.The air-conditioned condensate water in the polluted area is indirectly drained to the sewage pipes. The drainage of the medical area and the drainage of the ward are discharged into the sewage treatment station for treatment. The secondary biochemical treatment should be used to meet the requirements of the environmental impact assessment report and then discharged into the urban sewage pipeline and sent to the urban sewage treatment plant for further treatment. The sewage inspection well uses a sealed plastic drainage inspection well, and the inspection well should be equipped with an anti-fall net.
sewage treatment facilities are closed, and exhaust gas should be collected, disinfected and discharged after uniform collection. According to the actual conditions on site, the finished septic tank and disinfection tank are made of reinforced concrete. A fire hose reel water supply system is installed inside, which contains a 19mm fire hose reel, a length of 30m, and comes with a vacuum destroyer.
Indoors, according to the serious hazard level Class A fire, the portable ammonium phosphate dry powder fire extinguisher is added. The minimum configuration of a single fire extinguisher is 3A, and the maximum protection distance shall not be greater than 15m. CT, network computer rooms and other areas that are not suitable for water protection are all set up for heptafluoropropane gas fire extinguishing system. Adopt a prefabricated fire extinguishing system of heptafluoropropane.

Health Station isolation point and other major functional rooms have exterior windows, which can be used for natural ventilation. The public bathroom is equipped with a dedicated exhaust shaft and a ventilator with a check device, and a centralized unpowered ventilator is installed on the roof.
2 Square Hospital Ventilation
In order to ensure the orderly flow of airflow, form a reasonable pressure gradient, and avoid cross-infection, this project uses ventilation system design in accordance with the "Code for Building Design of Infectious Disease Hospitals" (GB50849-2014).
clean area design fresh air volume 3 times /h, and semi-polluted areas and polluted areas design fresh air volume 6 times /h.
sets up a mechanical air supply and exhaust system to make the building airflow organization form an orderly pressure gradient from the clean area (doctor's passage) to the semi-polluted area (medical corridor), and then to the polluted area (negative pressure ward). The difference in air supply and exhaust volume maintains the air pressure gradient in each area to prevent infectious air from seeping from the gap from the ward to the cleaning area and outdoors.
negative pressure ward uses airflow tissue that is sent up and discharged from the upper and lower. air supply vent is located in the ward corridor area, with a top air supply vent; 4 lower air exhaust vents with a bottom of 100mm from the ground are each installed on the outside of the bed head of the bed; so that the clean air can first flow through the possible working area of the Chinese medicine personnel in the room, and then flow through the source of infection and enter the air exhaust vent to prevent short circuits of the air supply and exhaust. The lower exhaust outlet at the bottom of the ward bathroom is 100mm away from the ground, which discharges the bathroom odor.
Each ward and clinic air exhaust branch is equipped with a multi-condition air control unit (with its own electric closed air valve), which can be turned off separately to disinfect the room. All air supply and exhaust ports are equipped with a capsule square constant air volume valve to ensure constant air volume in each room.
sets up delivery and exhaust units according to the supply methods of layered and partitions to reduce the ward ventilation operation system, which is conducive to layered and partitioned operation management and reduces operating costs.
All air supply systems are equipped with initial, medium and sub-high efficiency filters in the positive pressure section of blower to ensure clean air supply.
Install a fresh air inlet electrostatic dust removal air purification device at the fresh air inlet (negative pressure section) of the fresh air unit, with the initial resistance ≤ 30Pa. The fresh air inlet type electrostatic dust removal air purification device and the fresh air unit are connected to the joint control, and are turned on and stopped delayed. All exhaust systems in
contaminated and semi-polluted areas are equipped with initial, medium-effect filters and high-efficiency filters in the negative pressure section of exhaust fan , and pipeline-type ozone-free ultraviolet sterilization lamps are installed in the negative pressure section of the exhaust fan to be linked to the exhaust fan. To reduce exhaust air pollution or backflow affects the indoor environment during shutdown.
blower and exhaust fan are both installed outdoors on the first floor. The feeding and exhaust fans are arranged horizontally, and the minimum horizontal distance between the edges of the two should be greater than 20m. When the horizontal distance is less than 20m, the exhaust outlet should be higher than the air inlet and should not be less than 6m. The exhaust port should be no less than 3m higher than the roof, and the air port should be equipped with a conical hood and hood to discharge at high altitude. All delivery and exhaust fans of
use digital energy-saving centrifugal fan chassis. Fan equipment should be purchased for backup equipment so that the equipment failure can be replaced in time.
