1. The dimensions in this image: elevation in meters, all others in millimeters unless noted otherwise.
2. The pump station is designed with a scale of 0.05 m³/s, featuring two submersible污水 pumps, with one in use and the other as a spare.
3. Integrated pre-fabricated pump station equipment - The equipment listed is fully assembled and debugged by the manufacturer and supplied as a complete set. Technical briefing with the design institute is mandatory before production and ordering.
4. Pipeline and ground elevation details require further on-site verification.
5. This drawing is a process drawing, which details the specific component structures and orientations within the pump station. Manufacturers are free to make reasonable adjustments under the conditions of the process.
In addition to the above, the construction process should also adhere to the relevant national industry regulations and standards.
7. It is mandatory to assign a competent geological engineer to prepare the excavation plan and closely monitor the execution of the plan. The bottom of the pump pit must be dry and free of water; if water is present, appropriate dewatering measures must be taken. Adopt suitable pit maintenance methods to prevent the collapse of the pump pit. The bottom of the pit should be leveled, and if necessary, a layer of cobblestone or gravel should be laid, compacted with a roller, achieving a compaction level of 90% as per the compaction test results. If it is a sensitive area...
During the compaction operation, extreme caution must be exercised. The foundation must be capable of supporting a bearing capacity of no less than 140 kPa, and the backfill soil density must meet a minimum of 1.5 * 1003 kg/m².
