Integrated manufacturer of anti floating buried box pumps for the production of fire booster water supply equipment in underground fire pump stations

Description :

Underground fire pump stationFire booster water supply equipment water tanks can be mainly divided into three different types, and the products presented by these three different materials are also different. Let me take you to understand the differences between them! This article briefly discusses the importance of foundation engineering and construction management status in buried integrated fire water tank projects, and proposes specific measures to do a good job in foundation construction management for reference.

　　With the rapid development of the social economy, people's dependence on fire protection is also increasing. Therefore, integrated fire water tanks will inevitably have a huge impact on people's work and life, as well as the prosperity and stability of society. Especially for the construction of fire water tank foundations, which require strong technical expertise and large capital investment, and are prone to various problems during the construction process, it seriously affects the progress of fire engineering.

　　Material of buried integrated fire water tank

　　1、 Stainless steel material: commonly used for welding water tanks on the ground or roof. Stainless steel is also divided into 304 and 201 stainless steel, and the cost of stainless steel material is high.

　　2、 3.4 Composite board material: commonly used for integrated buried or anti floating box pumps. It is a commonly used material in the fire protection industry. It is made by one-time stamping of 3.0 galvanized steel plate and 0.4 stainless steel plate with a machine. It is characterized by good corrosion resistance, low price, and strong durability.

　　3、 Galvanized steel plate material: commonly used for buried water tanks. It is a material that is less commonly used in the fire protection industry and does not comply with fire safety regulations due to its lack of corrosion resistance.

　　The two words' buried integrated fire water tank 'are easy to understand, which means buried underground. The underground integrated fire water tank means that the water tank and the fire pump unit are integrated. The underground integrated fire water tank refers to separating a part of the space from the fire water tank and placing the fire pump unit directly inside the water tank, eliminating the design defect of covering a concrete pump room outside the water tank. This design saves costs and space. But there are also those who place the fire pump unit on top of the water tank, which also uses water tank panels to make a pump room on top of the water tank.

　　Schematic diagram of equipment foundation for buried fire pump station:

　　1. Design the foundation of the buried integrated fire water tank according to drainage requirements; The operating weight and top covering soil of buried water tanks

　　2. The equipment foundation is a two-layer seat foundation layer of mudstone and limestone, and the low-level bearing capacity value is designed according to fak=1000kpa

　　3. Concrete strength: The concrete strength of the bottom plate is c25, all of which are waterproof concrete with an impermeability grade of p6, a waterproof grade of 2, a cantilever grade of c25, and a cushion layer of c15

　　4. The thickness of the entire board foundation is 250mm, and there must be a distance of at least 800mm between the edge and the breakthrough position for seat installation space

　　5. In addition to meeting the design elevation, the base elevation also needs to enter the bearing layer by 300mm; a 100mm thick C15 plain muddy soil cushion layer should be made under the bottom plate

　　6. Slope protection is required around the excavation to avoid tower defense during construction

　　7. The reinforcement of the foundation slab is usually double layered and bi-directional

　　8. Admixtures: Construction shall refer to the "Technical Specification for Application of Concrete Admixtures" GB50119-2003. SY-K mixed expansion fiber crack resistant waterproofing agent can be used, and the parameters are mainly determined by different manufacturers' ratios.

　　9. Refer to the plan drawing 16G106-3 for detailed drawings of steel reinforcement structures related to local annotations
