Commonly Seen Repair Methods and Requirements for Aquatic Rides-type Amusement
Devices
C.1 Repair of Glass Fiber Reinforced Plastic Parts
C.1.1 Before the repair of glass fiber reinforced plastic parts, in accordance with the design
drawings, formulate a repair scheme; clarify the procedures and steps of disassembly and
installation, necessary tools and equipment for construction, as well as requirements,
instruments and measuring tools for post-repair inspection, etc.
C.1.2 Large glass fiber reinforced plastic shell and cockpit shall be hoisted with slings, and
measures of preventing deformation and damage of the glass fiber reinforced plastics shall be
taken. The glass fiber reinforced plastics and the ground shall be isolated by soft materials. No
flame operation shall be performed near the glass fiber reinforced plastic parts.
C.1.3 Glass fiber reinforced plastics with defects, for example, surface cracks, deformation or
damage, shall not be installed.
C.1.4 The connecting interface part of the glass fiber reinforced plastic slide and the inner and
outer sides of the bolt holes shall be cleaned and glued to be uniform and continuous; there shall
be no omission or leakage of glue.
C.1.5 When connecting the slides, firstly, align two sections of slides; use positioning pins to
locate them; adopt stainless steel bolts for connection and take anti-loosening measures.
C.1.6 The interface of the slide shall be level and smooth; there shall be no sharp corners or
burrs. There shall be no reverse order difference along the sliding direction; the forward order
difference shall not be greater than 2 mm.
C.1.7 After each segment (section) of glass fiber reinforced plastic slide is hoisted in place, the
end face coordinates shall be measured. After the measurement result complies with the design
requirements, the installation may be continued, otherwise, adjustment shall be made in time,
and no instruments shall be used for forceful adjustment.
C.2 Repair of Weld Defects
C.2.1 The weld defects of the steel structure of aquatic rides-type large-scale amusement
devices are repaired by welding, and mainly through the mode of repair welding, with the
purpose of repairing cracks and compensating for wear. The selection of welding materials,
process, inspection and repair shall comply with the design documents and the stipulations of
GB 8408, so as to control the welding quality.
C.2.2 For on-site welding, in accordance with the qualified welding processes and evaluation
reports, the welding process shall be formulated. In addition, the welding shall be performed
strictly in accordance with the welding process. If necessary, welding process specimens shall
be produced on the site and pass the evaluation. On-site welding operation shall not be
performed on the parts where on-site repair welding is not allowed in the design documents.
C.2.3 When one of the following circumstances occurs on the site of welding, corresponding
protection measures shall be taken to satisfy the welding requirements, otherwise, welding shall
not be performed:
a) wind speed: for gas shielded welding, greater than 2 m/s; for other welding methods,
greater than 10 m/s;
b) relative humidity: greater than 90%;
c) rain and snow environment;
d) weldment temperature is lower than -10 C.
C.2.4 For long-distance welding (above 20 m) on the construction site, the length of cable
extension shall be compatible with the cable diameter (cross-sectional area); the cables cannot
be used in coils during operation. Before welding, the welding machine shall be debugged to
ensure that the output voltage of the welding cable is consistent with the value displayed on the
voltmeter of the welding machine.
C.2.5 The welding process shall have welding records. After welding, in accordance with the
requirements of the design documents and relevant standards, conduct non-destructive testing
or tests to ensure that the welding quality complies with the requirements.
C.3 Others
For other mechanical parts and electrical equipment that need to be repaired for health recovery
due to wear, tear, deformation, fatigue and corrosion, a specific repair scheme shall be
formulated. Repair shall be carried out in accordance with the specified process through
disassembly of equipment parts, replacement of damaged parts (including electrical control and
safety devices), assembly and system debugging.
