Application of integrated prefabricated pumping station
Burks Prefabricated pumping station is suitable for sewage disposal where gravity can not be relied on. It collects sewage below sewage level through sewage tank and is far from municipal sewage network.
Wastewater discharged from sewage pipes and sanitation facilities is transported to the sewage pipe network by means of the lifting of Sewage pumps.
application area
1. Urban rainwater and sewage drainage
2. Rain and sewage drainage in shopping malls of residential districts
3. Drainage of Railway and Highway Passenger Stations
4. Emergency Drainage of Rainfall and Flood
Advantage
1. Burks integrated pumping station system has high integration, small area and compact equipment.
2. When the pre-installed pumping station is transported to the site, only the excavation of the foundation pit is completed.

2. The guide rail is made of reliable material and has good corrosion resistance.
3. Pump outlet and pipeline are closely connected to ensure the efficient operation of the device.
Notes on Submersible Pump Selection
1. The medium temperature shall be below 40°C and the medium pH shall be 5~9 (except for special customisation).
2. burks products are currently available in three speeds — 2900 rpm, 1450 rpm and 960 rpm — corresponding to different pump types. We will select the most cost-effective product that meets the user's requirements.
3. The station must not be installed in a pump pit deeper than the allowable water depth.
Transportation Notes
When unloading the pumping station, flexible lifting slings, belts or lifting ropes shall be used; steel wire ropes or chains are strictly prohibited. Lifting must be carried out by two-point hoisting, and the station shall be placed on flat ground.
When lifting the station from the horizontal position to the vertical position, the lifting lugs on the station must not be used, so as to avoid stress concentration damaging the cylinder.
When the station is lowered vertically from the ground into the pump pit, a balancing lifting beam must be used to prevent the upper pump cover from being pinched and damaged by the slings.
Installation Plan
Before the pumping station is installed, an installation plan shall be prepared, covering the following aspects: 1. excavation plan; 2. foundation plan; 3. civil works plan; 4. foundation pit drainage plan. The most important of these is the excavation plan, which should normally be prepared by a professional geological engineer and followed up during installation to avoid subsequent difficulties. When, after survey, the geological conditions of the project site meet the requirements, the foundation pit shall be excavated with local or full sloping, and the slope gradient shall meet its stability requirements. When the geological conditions on site do not meet the requirements for open excavation, we recommend selecting the corresponding foundation pit support conditions according to the following safety grades.
Safety Grade of Foundation Pit Side Walls and Importance Coefficient
| Grade 1 | If the support structure fails, soil instability or excessive deformation will have a very serious impact on the surrounding environment of the foundation pit and the construction of underground structures; importance coefficient γ0 = 1.10 |
| Grade 2 | If the support structure fails, soil instability or excessive deformation will have a general impact on the surrounding environment of the foundation pit and the construction of underground structures; importance coefficient γ0 = 1.00 |
| Grade 3 | If the support structure fails, soil instability or excessive deformation will have no serious impact on the surrounding environment of the foundation pit and the construction of underground structures; importance coefficient γ0 = 0.90 |
Support Structure Selection Table
| Row piles or diaphragm wall | 1. Suitable for foundation pit side-wall safety grades 1, 2 and 3; 2. Cantilever structures should not be greater than 5 m in soft soil sites; 3. When the groundwater level is higher than the bottom of the foundation pit, dewatering, row piles with a water cut-off curtain, or a diaphragm wall should be adopted |
| Cement-soil wall | 1. The foundation pit side-wall safety grade should be 2 or 3; 2. The bearing capacity of the foundation soil within the cement-soil pile construction area should not be greater than 150 kPa; 3. The foundation pit depth should not be greater than 8 m |
| Soil nail wall | 1. Soft soil sites with foundation pit side-wall safety grade 2 or 3; 2. The foundation pit depth should not be greater than 12 m; 3. When the groundwater level is higher than the bottom of the foundation pit, dewatering or water cut-off measures shall be adopted |
| Top-down arch wall | 1. The foundation pit side-wall safety grade should be 2 or 3; 2. Not suitable for silt and silty soil sites; 3. The rise-to-span ratio of the arch wall axis should not be less than 1/8; 4. The foundation pit depth should not be greater than 12 m; 5. When the groundwater level is higher than the bottom of the foundation pit, dewatering or water cut-off measures shall be adopted |
| Sloping | 1. The foundation pit side-wall safety grade should be 3; 2. The construction site must meet the sloping requirements; 3. Can be used independently or in combination with the other structures above; 4. When the groundwater level is higher than the slope toe, dewatering measures shall be taken |
Prefabricated Foundation
1. The sewage tank shall be installed on a concrete foundation.
2. The pit bottom shall be levelled and compacted with a compactor. If the pumping station is large in volume and high in height, deep foundation piles shall be driven in advance as required by the anti-floating calculation.
3. The anchor bolts fixing the pumping station on the concrete foundation shall be embedded in advance; where expansion bolts are used, holes may be drilled on site.
4. The concrete foundation shall be prefabricated in advance and lifted into place by crane.
Backfilling
1. After the pumping station is in place and its verticality has been checked, backfilling can begin. Fine sand shall be used as the backfill material, and the particle size must not exceed 30 mm, so as to avoid damage to the tank.
2. Backfilling shall be carried out layer by layer, with each layer 0.5 m high.
3. Each layer shall be compacted after backfilling. The compactness shall reach 0.9, and the dry unit weight shall not be less than 15.5 kN/m³. During backfilling, the area around the foundation pit shall be filled evenly to prevent excessive soil on one side from tilting the tank.
4. The soil under the inlet and outlet pipes in the pit shall be compacted, so as to provide corresponding support if the pumping station settles. The use of an earth rammer for compaction is strictly prohibited.
This product is warranted for one year from the date of purchase against failures caused by non-human factors under normal use (see the warranty certificate in the user manual for details).
