[0001] This utility model belongs to the field of integrated equipment technology, and relates to a special underground pumping station for railway transportation projects, and in particular to a fully underground prefabricated integrated water supply pumping station for railway systems. Background Technology

[0002] With the rapid development of industrial sectors, the demand for road transportation is gradually increasing. The passenger flow in cities in developed economic regions is constantly increasing, and the demand for water supply for railway transportation is becoming more and more urgent.

[0003] Currently, railway fire-fighting water supply systems generally utilize concrete water tanks. However, the construction process for concrete water tanks is complex, involving numerous procedures (including formwork, rebar tying, pouring, and curing), resulting in a long construction period and significant susceptibility to seasonal and weather conditions. Furthermore, the structural and construction requirements of concrete water tanks impose specific conditions on the construction site. In addition, the heavy weight of concrete water tanks makes them prone to uneven settlement; the low load-bearing capacity of the tank surface prevents reuse, and water quality cannot be guaranteed. In summary, various combined factors have a significant impact on the construction and renovation of railway fire-fighting water supply facilities.

[0004] Therefore, there is an urgent need for a water supply facility for railway systems to solve the above problems. Summary of the Invention

[0005] To address the aforementioned issues, this utility model discloses a fully underground prefabricated integrated water supply pumping station for railway systems, which has a shorter construction period, shorter installation period, smaller construction volume, is easier to move and disassemble, and can be reused compared to traditional pumping stations.

[0006] When constructing railway system projects, the installation and commissioning time of the pump station of this utility model is greatly shortened compared with that of traditional pump stations; at the same time, the pump station of this utility model is more cost-effective and occupies less space than traditional concrete pump stations.

[0007] In summary, this utility model pump station has unparalleled advantages over traditional concrete pump stations: small size (the sunken design maximizes the use of available water, reducing volume by approximately 95% compared to traditional concrete pools), new materials, low cost, high integration, safe operation, time-saving and labor-saving installation and maintenance, low requirements for installation season, weather, and site, and recyclable; all metal components undergo special anti-corrosion treatment, extending their service life and adapting to various harsh working environments. It represents a significant advancement in integrated equipment and an optimization of pump station systems, possessing broad application prospects.

[0008] The technical solution of this utility model is as follows:

[0029] The side walls and top of the water tank 1 and the pump room 2 are assembled from multiple modular panels using bolts and sealing strips. The modular panels are integrally formed metal modular panels.

[0030] Preferably, the module is a high-rigidity molded module for assembled stainless steel water tanks as described in Chinese Patent ZL2015211181034.

[0031] The pump station foundation is set in a pit, including a concrete cushion layer (C15 concrete cushion layer 3) and a concrete slab foundation (C30 concrete raft slab 4) arranged from bottom to top.

[0032] The C30 concrete raft slab 4 is connected to the bottom side walls of water tank 1 and pump house 2 via a secondary concrete pouring process. Specifically, grooves are created on the C30 concrete raft slab 4 at positions corresponding to the four sides of water tank 1 and pump house 2.
