FRP Integrated Pumping Station

The integrated prefabricated FRP (Fiber-Reinforced Polymer) pumping station is a novel type of sewage lifting device that utilizes FRP piping as its flow-carrying component and pumps as its motive power equipment.
It offers numerous advantages, including ease of installation, stable operation, and a long service life; furthermore, it allows for significant savings in construction investment and land resources.

Structural Components of the Integrated Prefabricated FRP Pumping Station:
1. Foundation Section (including the ground slab, base, concrete well walls, etc.)
2. Inlet Chamber
3. Outlet Chamber
4. Inlet and Discharge Piping System
5. Control Cabinet
6. Electrical Control System
7. Pipe Supports
8. Cable Trench
9. Lighting Facilities
10. Lightning Protection and Grounding System

Construction Methodology:
1. Earthwork Excavation:
The elevation of the trench bottom should be approximately 0.1 meters above the groundwater level
2. Layout and Positioning
3. Foundation Pit Support
(1) Underground Continuous Wall Enclosure
(2) Underground Waterproof Slab Enclosure
(3) Rock Anchor Retaining
(4) Internal Support using Steel Mesh and Cement Mortar
(5) Steel Sheet Pile Enclosure
(6) Crushed Stone Cushion Layer

Foundation Pouring:
1. Concrete Pouring for the Base Slab
2. Installation of Formwork for the Top Slab
3. Installation and Commissioning of Vertical Axial-Flow Pumps
4. Installation and Commissioning of Horizontal Centrifugal Pumps
5. Installation of the Piping System
6. Wiring of Electrical Equipment
7. Trial Run
8. Final Acceptance

Precautions:
1. During foundation treatment, care must be taken to prevent water infiltration into the foundation pit
2. The compaction density of the foundation concrete, achieved through vibration, must exceed 95%
3. During winter construction, adequate thermal insulation measures must be implemented
4. During summer construction, appropriate sun-shading measures must be adopted

Scope of Application:
The integrated prefabricated FRP pumping station boasts a wide range of applications. It is suitable for use in urban sewage treatment plants or industrial wastewater discharge systems—specifically for preliminary rainwater collection, intermediate-stage advanced sewage treatment, and final-stage sludge dewatering processes.
