high strength fiberglass  inspection chamber / inspection shaft

FRP Manhole is made of  fiberglass, resin as the main raw material, and add relevant materials made of a light weight, high strength, corrosion resistance, transportation and installation quick and easy, smooth wall, good water conditions and so on. According to characteristics of the project, in accordance with user requirements for processing, flexible
FRP Manhole easy installation, light weight, easy to transport and install, reliable performance, strong bearing capacity, impact resistance, corrosion resistance, aging resistance, easy connection to the plastic pipe, sealing, and effectively prevent water leakage, safety and environmental protection ; smooth wall smooth, easy dirt retention, reducing the possibility of clogging, emission rates greatly enhanced; wellbore field cut, adjust, adapt to a variety of mounting depth requirements, reduce cost, all-weather construction. Greatly improved the construction schedule, the construction rate is 10 - 20 times more than traditional inspection wells.

inspection shaft feature

1, good corrosion resistance
FRP Manhole resistant to acid, alkali, salt, water, untreated sewage, corrosive soil or groundwater, and many chemical fluid erosion. Long service life than traditional materials well chamber, the design life of up to 30 years. FRP Manhole, since it has no need to corrosion, greatly extended service life, easy installation, etc., therefore, has been widely welcomed and drainage industry

2, stain resistant borers
FRP Manhole unsaturated polyester resin surface clean and smooth, not sewage A shellfish, fungi and other microbial contamination borers attached, so as to increase roughness, increased maintenance costs.
3, heat resistance, frost resistance
FRP Manhole at -30 ℃ condition, still has good toughness and high strength, long-term use in a range of -50 ℃ -80 ℃, using specially formulated resin can also work in temperatures of more than 110 ℃.

4, low maintenance costs
FRP Manhole corrosion due to the above, frost and dirt and other properties, and therefore does not require corrosion engineering and maintenance measures can save a lot of engineering and maintenance costs.
5,strong  adaptable
FRP Manhole according to various specific requirements of the user, such as different pressures, different depths and load conditions, design and manufacture of a different specification levels well chamber structure to meet the actual needs of the project.
