Commercial Fiberglass Water Slide Installation Guide

Note: This guide applies to children's water slides, open slides, and enclosed spiral fiberglass water slides.

I. Pre-Installation Preparation

1. Qualification and Document Verification

① Manufacturer: Amusement facility production license, design appraisal report, type test report, factory certificate of conformity, fiberglass material report, equipment general drawing, foundation drawings, installation instructions, bolt torque parameters, lubricating water flow parameters.

② Installation Unit: Large-scale amusement facility installation permit; operators must be certified.

③ Civil engineering unit: Strictly follow the manufacturer's foundation embedded part drawings during construction; arbitrary modification of foundation position, elevation, and load on site is strictly prohibited.

2. Site Condition Confirmation

① Site: Clean the hoisting operation area; plan crane station positions and component stacking areas; verify foundation coordinates, elevation, and embedded bolt hole positions; installation can only proceed after the foundation concrete reaches 100% of its design strength.

② Verify key parameters: Slide platform elevation, slide exit elevation, and water depth in the drop-off pool (must be completely consistent with the equipment manual; insufficient water depth greatly increases the risk of injury from bumps and knocks).

③ Component arrival inspection

◦ Fiberglass: No cracks, no delamination, and no large-area damage to the gel coat; slide body thickness ≥ 6mm, flange thickness ≥ 8mm.

◦ Steel structure support: Hot-dip galvanized for corrosion protection, zinc coating ≥ 85μm; welds free of porosity and cracks.

◦ All bolts are made of 304/316 stainless steel, with matching spring washers and anti-loosening washers; ordinary carbon steel bolts must not be used in direct water immersion environments.

④ Tools: Total station/level, torque wrench, hoisting equipment, scaffolding, sealant, and sealing strips.

II. Key Points for Civil Engineering Foundation and Embedded Part Construction (Most Prone to Problems)

1. Position embedded parts according to the manufacturer's template, verify coordinates with a total station, elevation error ≤ ±20mm; ensure anchor bolts are securely welded, install anti-buoyancy and anti-shear structures, and apply anti-corrosion treatment to the foundation.

2. Ensure unobstructed drainage around the foundation to prevent water accumulation and immersion.

3. Reserve lubrication water supply sleeves for the sliding platform, positional deviation ≤ 4mm.

4. Maintain photographic and test block reports for all concealed foundation works, archive all data, and ensure no data is lost before equipment is scrapped.

Prohibited: Do not call the manufacturer for adaptation after foundation completion; strictly prohibit on-site cutting and alteration of embedded parts to directly align with the sliding track.

III. Overall Installation Sequence

Foundation Verification → Steel Structure Support Column and Main Beam Hoisting and Welding → Sliding Platform Installation → FRP Slide Section Ground Pre-assembly → Slide Hoisting and Positioning → Flange Tightening and Sealing → Guardrail/Side Panel Installation → Lubrication Water Supply Pipeline → Drainage Pool Confirmation → Visual Repair → No-Load Commissioning → Load Testing → Self-Inspection → Application for Special Equipment Inspection

1. Steel Structure Support Installation

① Columns are installed sequentially from lowest to highest; vertical deviation of columns is controlled within 1/1000.

② Important load-bearing welds undergo non-destructive testing; post-weld anti-corrosion treatment is applied to prevent weld rust and cracking.

③ Rubber shock-absorbing pads are added between the support bracket and the FRP slide; FRP must not come into direct contact with steel components to avoid cracking caused by operational vibration.

2. Segmented Assembly of the Fiberglass Slide (Core Process)

① Pre-assemble 2-3 sections on the ground first, check flange fit, eliminate misalignment, and then hoist the entire assembly to reduce the risk of working at height.

② Clean the flange mating surfaces thoroughly, removing burrs and dust; insert water-resistant and aging-resistant special rubber sealing gaskets; do not use sealant alone instead of sealing strips.

③ Tighten bolts evenly diagonally, strictly according to the manufacturer's specified torque value; apply Vaseline to the threads for rust prevention and anti-loosening measures; record the torque value for each flange assembly and keep a record.

④ Do not force assembly by prying or pulling; forced alignment will cause internal stress at the root of the fiberglass flange, leading to cracking after operation.

⑤ After assembly, the misalignment height of the inner wall of the slide should be ≤1mm; protrusions and steps on the inner wall may scratch the skin of visitors.

⑥ Apply water-resistant epoxy sealant to the outside of the joint, and use as little sealant as possible on the inside to prevent sealant from falling into the pool.

3. Slide Platform, Guardrails, and Safety Measures

① Guardrail height: ≥1.1m for children's slides; net clearance between vertical guardrails ≤110mm to prevent head injury.

② Anti-slip paving on the platform; water-blocking and limiting baffles at the slide starting point are complete.

③ Check ventilation openings for enclosed slides; enclosed slides should not be completely sealed to prevent air suffocation.

4. Lubrication Water Supply System Installation

① Slides must be equipped with a dedicated lubrication water supply; the flow rate must strictly adhere to the equipment manual; insufficient water flow will cause the slide to jam, while excessive water flow will cause the slide to overflow.

② Install valves and filters on the pipes; align the outlet with the starting position of the slide, ensuring the water flow evenly covers the bottom surface of the slide.

③ Secure the pipes to prevent water pressure impact and vibration.

5. Slide Exit and Drainage Pool

① The dimensions and water depth of the exit buffer zone must conform to the manufacturer's drawings; insufficient water depth is a major safety hazard.

② No protruding components or sharp corners around the outlet; all pool walls have rounded corners.

③ Confirm that all return water inlets are equipped with anti-adsorption covers.

IV. Commissioning and Testing Procedures (Trial operation is not permitted without testing after installation)

1. Appearance and Structural Self-Inspection

◦ Check the torque and loosening of all bolts; ensure all steel structures are properly protected against corrosion; ensure the fiberglass is free of cracks; ensure the inner wall of the slide is free of steps and burrs.

◦ The guardrails and handrails are intact and secure.

2. Water-Powered No-Load Trial Run

◦ Turn on the lubrication water pump and run it continuously for at least 2 hours; check for leaks at the flange joints; observe the water flow distribution within the slide.

3. Simulated Load Test Use sandbags to simulate human weight, slide repeatedly, and observe: whether the slide vibrates abnormally, whether the supports are deformed, whether the exit landing point is normal, and whether there is a risk of being thrown out.

4. Clean the Slide Interior: Remove dust, adhesive residue, and metal shavings to prevent scratches to visitors.

V. Special Equipment Inspection and Acceptance Process (Mandatory for Commercial Amusement Parks)

1. The installation unit submits an installation notification to the municipal market supervision bureau before construction.

2. Upon completion of installation, the installation unit issues an installation self-inspection record.

3. Apply to the special equipment inspection agency for installation supervision and inspection, submitting the following documents:

◦ Manufacturing license, installation license; design appraisal, type test report; factory data; basic data; installation record, torque record; equipment data sheet.

4. After passing the on-site inspection by the special equipment inspection agency and obtaining the "Supervision and Inspection Report," register for use, and affix the inspection qualification mark, the equipment can officially commence operation.

VI. Common Fatal Installation Mistakes (Avoidance Checklist)

1. Ordinary carbon steel bolts are used directly in humid water environments, leading to corrosion and breakage later.

2. Flange connections are sealed only with sealant, without rubber gaskets, causing water leakage into the interlayer and delamination and cracking of the fiberglass.

3. Forcibly prying and aligning the sliding flange causes pre-embedded stress in the fiberglass root, leading to breakage later.

4. The water depth and lubricating water flow rate in the drop-off pool do not conform to the manufacturer's parameters, causing accidents such as bumps and being swept out of the slide.

5. The supporting steel structure is directly topped with fiberglass without rubber shock-absorbing pads, leading to cracks due to vibration.

6. The vertical gaps in the guardrails are greater than 110mm, posing a risk of children getting their heads stuck.

7. Opening for business without obtaining special equipment installation notification and inspection constitutes illegal operation.

8. Excessive misalignment of the inner wall joints of the slide can cause skin scratches.

VII. Handover for Operation: List of Documents to be Delivered

1. Complete set of as-built drawings; foundation as-built data; fiberglass and steel structure material certificates.

2. Torque record sheet for each flange bolt; weld inspection report.

3. Manufacturer's operation and maintenance manual: including daily inspection points, tightening cycle, fiberglass repair methods, lubricating water parameters, and prohibited actions.

4. Complete set of special equipment documentation (notification form, inspection report, usage registration data).
