1. Project Background
Water resource conservation is a key public infrastructure focus in the United States. Many local irrigation and water delivery canals have served for decades.
These traditional canals mostly use concrete lining or natural soil structures. They face serious water leakage problems all year round.
Long-term water seepage causes huge waste of fresh water resources. It also leads to uneven ground settlement along the canal.
The canal slopes often crack and collapse in rainy and dry alternating seasons. This damages the stability of the entire water delivery system.
In addition, leaked canal water easily carries sediment and agricultural chemicals into underground soil and groundwater.
It causes potential environmental pollution risks. It increases the daily maintenance cost of local water conservancy departments.
To solve these problems, the local water conservancy bureau launched a canal upgrading and renovation project. The core goal is to reduce water seepage, extend canal service life and improve water delivery efficiency.
After strict product screening and solution comparison, the client finally chose BPM professional impermeable membrane liner products and overall lining solutions.
2. Key Project Challenges
The construction environment and functional requirements of this American canal project bring many strict challenges.
First, the canal covers a long distance with complex terrain. The canal base has uneven soil and scattered small sharp stones. Ordinary thin lining materials are easy to be punctured and damaged during use.
Second, the local climate has obvious seasonal differences. Summer has high temperature and strong ultraviolet radiation. Winter has low temperature and frost.
The lining material must resist aging and low-temperature cracking.It needs to keep stable performance in long-term outdoor exposure.
Third, the project requires ultra-low permeability. The client has strict standards for water seepage rate. The lining system must form a complete closed waterproof structure. No leakage points are allowed in the long-term operation process.
Fourth, the construction period is tight. The project needs to be completed before the local irrigation season. The selected materials must be easy to transport and install. They need to adapt to rapid on-site construction and shorten the project cycle.
Most traditional lining materials cannot meet the above comprehensive requirements. Traditional concrete lining has poor flexibility and is easy to crack. Ordinary plastic films have low strength and weak anti-aging ability.
Therefore, the client needed a high-performance, durable and cost-effective canal impermeable lining product.
3. BPM Customized Canal Lining Solution
As a professional manufacturer and supplier of geosynthetic materials, BPM has rich experience in global water conservancy and canal lining projects.
According to the actual site conditions and technical standards of the USA canal project, our technical team designed a targeted HDPE impermeable membrane liner solution.
The main product adopted is BPM high-density polyethylene (HDPE) impermeable membrane with a thickness of 2.0mm.
This product is specially optimized for canal water seepage prevention scenarios. It has excellent physical and chemical stability. It is the most suitable material for large-scale canal lining renovation and new construction projects.
First, BPM HDPE canal liner has ultra-low permeability. Its internal molecular structure is dense and uniform. It can effectively block water penetration.
It greatly reduces the water seepage rate of the canal. It ensures stable water volume in the water delivery process.
Second, the product has high tensile strength and puncture resistance. It can resist the friction and impact of canal base soil and stones.
It avoids material damage caused by terrain changes and external forces. It adapts to the complex and uneven foundation conditions of the project site.
Third, BPM canal impermeable membrane has strong weather resistance. It adds special anti-ultraviolet and anti-aging ingredients during production.
It can resist long-term sun exposure, high temperature oxidation and low-temperature frost cracking. It will not deform, harden or leak after years of outdoor operation. The service life can reach more than 25 years.
Fourth, the material has good flexibility and ductility. It can adapt to slight foundation settlement and slope deformation of the canal. It effectively solves the cracking and leakage problems of traditional rigid lining materials. It improves the overall stability of the canal structure.
In addition to high-quality products, BPM also provides one-stop supporting services. Our professional technical team provided on-site construction guidance for the USA project.
We formulated standardized laying, welding and fixing processes. We ensured the perfect combination of products and on-site construction to guarantee the project quality.
4. On-site Construction Process
The construction of this USA canal lining project strictly follows international geotechnical engineering construction standards. The whole process is standardized and efficient, which ensures the final anti-seepage effect and project quality.
The first step is site preparation and foundation treatment. The construction team cleaned all sundries, sharp stones and weeds on the canal base and slope. They leveled the uneven soil surface.
A flat, clean and stable foundation surface was formed to prepare for membrane laying. This step avoids sharp objects piercing the impermeable membrane and affects the anti-seepage effect.
The second step is geotextile cushion laying. Before paving the impermeable membrane, a layer of non-woven geotextile was laid on the canal base. The geotextile acts as a buffer and protection layer.
It reduces the friction between the membrane and the foundation. It further prevents the membrane from being punctured. It also plays a role in drainage and isolation.
The third step is HDPE impermeable membrane laying. BPM large-size membrane rolls were used for laying. The membrane was laid flat along the canal slope and bottom.
We reserved a reasonable expansion joint gap according to the local temperature change characteristics. This prevents the membrane from shrinking and cracking in low temperature or bulging and deforming in high temperature.
The fourth step is hot-melt welding and seam inspection. All overlapping joints of the membrane adopt professional hot-air fusion welding technology. The welding seam is tight and seamless to form an integral waterproof structure.
After welding, the staff conducted strict air leakage detection and visual inspection on all welding parts. No missing welding, virtual welding or leakage points were allowed.
The fifth step is edge fixing and protective backfilling. After the membrane laying and welding were completed, the membrane edges were fixed with special fixing parts.
Soil and fine sand were backfilled and compacted on the surface. The overall protection of the lining system was completed to ensure long-term stable operation.
