Wuhan University of Technology Innovation Fiberglass Anti-Corrosion Project

Construction Plan

Construction Process Introduction

This project Introduction to general pool anti-corrosion engineering, The surface is coated with epoxy fiberglass, specifically three layers of fabric and five layers of resin. Anti-corrosion Engineering The specific construction process is divided into the following steps:

1. Preparations:

① Ensure the cement floor is completely dry before construction. The cement strength has reached more than 80% of the design strength. Foundation leveling The error per meter is within 1–1.5 mm. 、 The surface shall be kept clean and dry, Only then can the base coat application proceed. ， Avoid construction during the hottest part of the day. 。

② Prepare the fiberglass raw materials and construction equipment required for the project. ， In addition, implement basic fire‑prevention measures, ensure that personal protective equipment and safety precautions are in place, prepare a construction plan, and conduct technical and safety briefings for all workers to ensure safe and civilized construction practices.

③ Conduct incoming inspection of equipment to check for damage and other safety hazards; sort materials and stack them by category in designated areas, clearly marking each pile to ensure they remain dry and uncontaminated. Have qualified laboratory personnel perform testing and verification on the materials, record the relevant data, and retain the results for use during construction.

2. The specific construction procedure is as follows: ( Three layers of cloth and five layers of oil ):

1. Applying the epoxy coating: Begin by applying the first coat to corners and other hard-to-reach areas, ensuring uniformity throughout. Then proceed to coat the remaining surfaces, overlapping each pass by approximately 30–50 mm. After the first coat has cured, repeat the process for a second application, paying particular attention to corners and other difficult-to-access areas.

2. Inspect the coated surface for burrs that require sanding, as well as for any areas where coating is incomplete or the coating thickness is insufficient, among other potential issues. Only after passing inspection may the next construction step proceed. Following successful inspection, apply fiberglass cloth; the fiberglass cloth must be applied in layers and firmly compacted, and it is strictly prohibited to apply two or more layers simultaneously.

The joints of the fiberglass shall be staggered, and the lap at the seams shall be no less than 50 mm.

3. After the fiberglass has cured, inspect for common defects such as blistering, resin bleeding and whitening, or delamination, as well as any hidden issues. If any non‑conformities are found, a corrective action plan must be developed by qualified technical personnel; unauthorized modifications by the construction team are strictly prohibited. For the aforementioned defects or other unforeseen problems arising from causes not attributable to the contractor, resolve them in accordance with the contract terms if such provisions exist; otherwise, seek resolution through mutual agreement with the client. Upon successful inspection, apply the final coat of epoxy sealant, following the same procedure as the first coat.

    4 , Finished Product Protection: Throughout the aforementioned process, a specified curing period is required (the exact duration to be determined by the construction plan and schedule). During this curing phase, the project must be protected by erecting perimeter barriers and posting warning signs; where necessary, dedicated personnel may be assigned to provide on‑site supervision.

Number of Participants Plan

1. It shall be determined in accordance with the contractually agreed construction period and the specific scale of the project.

2. At least one safety officer and at least one laboratory technician are required.

Quality Requirements

1. According to the construction plan and the site conditions On-site situation Situation Ensure that construction work at each stage is carried out properly, Perform self-inspection, Mutual inspection and Special Inspector Special inspection to meet quality requirements.

2. No item may proceed to the next process without inspection, and critical control items must achieve 100% compliance.

Safety measures

1. Since the raw materials used in construction are flammable, A dedicated warehouse must be established, staffed by designated personnel and equipped with fire‑fighting facilities. All construction personnel entering the site are prohibited from smoking, and open flames are strictly forbidden.

2. Construction personnel enter the site. Real-name registration is mandatory, and personal protective equipment must be worn properly. Comply with all rules and regulations and follow the supervisor’s instructions.

3. During the application of porcelain enamel, a ventilation system must be in place to supply fresh air and maintain good air quality inside the tank, or workers should wear gas masks to ensure safe and effective work. ， A dedicated supervisor must be present to oversee the operation, and appropriate emergency equipment and an emergency response plan must be in place. 。

Completion Acceptance

Anti-corrosion Engineering Upon completion of all construction works, the workers shall conduct a self‑inspection and, upon passing it, submit the work to qualified professionals for review. Any issues identified during the professional inspection shall be rectified and addressed. Once the professional inspection is passed, a request for竣工验收 (completion acceptance) shall be submitted, and the Employer shall carry out the acceptance process. Upon successful acceptance, an acceptance report and relevant documentation, including details such as the area treated with anti‑corrosion measures, shall be provided to request payment from the Employer.

Quality period and warranty period

The warranty period for quality is one year. During this period, if any defects arise that are attributable to the工程质量 itself, the contractor shall undertake repairs without condition, with all associated costs borne by the contractor. Upon expiration of the warranty period, if Party A does not raise any objections within one week, it shall be deemed that Party A has accepted the conclusion of the warranty period, and Party A shall promptly pay the contractor the corresponding quality‑guarantee deposit. The duration of the quality warranty shall be determined by the contract; in the absence of such an agreement, the applicable national standards shall apply; if no national standards exist, industry standards shall prevail; and if no industry standards are available, enterprise‑specific standards shall be followed. Should defects emerge during the post‑warranty but still within the quality‑assurance period, Party A shall have the right to require the contractor to address them, and the contractor may not refuse; all related costs shall be borne by Party A.
