Preparation before installation

1.Foundation production

• Foundation type: Design a concrete foundation or steel frame platform according to the size and shape of the water tank.

• Load-bearing requirements: The foundation must be able to withstand the weight of the water tank when fully loaded (water weight + tank weight).

• Flatness: The horizontal error of the foundation surface is ≤3mm to avoid deformation of the tank due to uneven force.

• Drainage design: Drainage ditches are reserved around the foundation to prevent water accumulation from corroding the bottom of the tank.

2.Check materials and tools

• Check whether the water tank module, bolts, sealant (such as neutral silicone), rubber gasket and other accessories are complete.

• Prepare tools: level, wrench, screwdriver, cleaning cloth, etc.

Water tank assembly steps

1.Bottom plate installation

• Put the bottom plate module flat on the foundation according to the drawing, align the joints, and use bolts to fix it initially.

• Use a level to check the flatness of the bottom plate, adjust it to be completely horizontal, and tighten the bolts.

2.Installation of side panels and partitions

• Sequence: Splice from the bottom layer to the top layer, and each layer of side panels needs to be installed with staggered seams (avoid through seams).

• Sealing treatment:

• Rubber sealing strips are embedded in the joints of the panels, and sealant is applied on the outside (thickness is about 2-3mm).

• Bolts need to be tightened evenly diagonally to prevent local stress concentration.

3.Top panel installation

• The top panel module covers the top of the side panel, and the joint treatment is the same as the side panel.

• Reserve the position of the inspection hole (manhole) to ensure that the opening size is consistent with the design.

Installation of key accessories

1.Pipeline connection

• Inlet and outlet pipes: flange connection, lined with rubber gaskets, check for leakage after tightening the bolts.

• Overflow pipe and sewage pipe: The overflow pipe mouth should be 5-10cm lower than the top of the water tank, and the slope of the sewage pipe should be ≥2% to facilitate drainage.

• Valves and instruments: Install water level gauges, valves, etc. for daily monitoring.

2.Safety accessories

• Install escalators and guardrails (1.2m above the top of the water tank), and lock the manhole cover to prevent foreign objects from entering.

• Lightning rods must be installed on outdoor water tanks, and the grounding resistance must be ≤10Ω.

Sealing test

1.Full water test

• Fill water to the designed water level, let it stand for 24 hours, and observe whether the joints and pipe connections are leaking.

• If leakage is found, drain the water and reapply sealant or adjust the tightness of the bolts.

2.Air pressure test (optional)

• Introduce 0.05MPa compressed air into the closed water tank, maintain pressure for 30 minutes, and the pressure drop is ≤10% to be qualified.

Environment and safety measures

Spacing requirements: reserve ≥0.8m maintenance passages around the water tank, and leave ≥0.5m space on the top.

Insulation and antifreeze: In cold areas, insulation materials (such as polyurethane foam) must be covered, and heating belts are activated when the water temperature is below 0℃.

Anti-pollution measures: Regularly clean and disinfect the inner wall of the water tank, and install insect-proof nets on the vents.

Acceptance and maintenance

1.Acceptance standards

• Sealing, verticality (deviation ≤1‰), water quality testing.

2.Daily maintenance

• Clean once every six months, check the aging of the sealant, and replace it in time.

• Drain idle water tanks in winter to prevent freezing and cracking.

3.Precautions

• Prohibited operations: Welding and knocking on the tank to avoid damaging the fiberglass layer.

• Professional construction: It is recommended that large water tanks (≥50m³) be installed under the guidance of the manufacturer to avoid structural errors.

• Emergency treatment: If cracks appear on the tank, stop using it immediately and contact the manufacturer for repair.
