玻璃钢检查井井室具有以下特点：
FRP inspection well chamber has the following characteristics:
1)耐腐蚀性好。
1) Good corrosion resistance.
玻璃钢井室能抵抗酸、碱、盐、海水、未经处理的污水、腐蚀性土壤或地下水及众多化学流体的侵蚀。比传统材质井室的使用寿命长，其设计使用寿命可达30年以上。
FRP well chamber can resist the erosion of acid, alkali, salt, sea water, untreated sewage, corrosive soil or groundwater and many chemical fluids. The service life of the chamber is longer than that of the traditional well chamber, and its design service life can reach more than 30 years.
对玻璃钢井室而言，由于其具有无需防腐、使用寿命大大延长、安装简便等优点，因此，受到了市政排水行业的广泛欢迎。
As for the FRP well chamber, it is widely welcomed by the municipal drainage industry because of its advantages such as no need of anti-corrosion, long service life and simple installation.
2)防污抗蛀。
2) Antifouling and mothproof.
玻璃钢井室的不饱和聚酯树脂表面洁净光滑，不会被污水中的甲贝、菌类等微生物玷污蛀附，以致增大糙率，增加维护费用。
The surface of unsaturated polyester resin in FRP well chamber is clean and smooth, which will not be contaminated by shellfish, fungi and other microorganisms in sewage, so as to increase the roughness and maintenance cost.
3)耐热性、抗冻性好。
3) Good frost resistance and heat resistance.
在-30℃状态下，仍具有良好的韧性和极高的强度，可在-50℃－80℃的范围内长期使用，采用特殊配方的树脂还可在110℃以上的温度工作。
At - 30 ℃, it still has good toughness and high strength. It can be used for a long time in the range of - 50 ℃ - 80 ℃. The resin with special formula can also work at the temperature above 110 ℃.
4)自重轻、强度高，运输安装方便：
4) Light weight, high strength, convenient transportation and installation
采用纤维缠绕生产的玻璃钢井室，其比重在1.8－2.0，但强度可达50-120Mpa，这样它就可以按用户的不同要求，设计成满足各类承受内、外压力、轴向受力要求的结构。它与配管之间的承插连接方式，安装快捷简便，同时降低了吊装费用，提高了安装速度。
The fiberglass reinforced plastic well chamber produced by filament winding has a specific gravity of 1.8-2.0, but its strength can reach 50-120mpa. Thus, it can be designed to meet the requirements of various types of internal and external pressure and axial stress according to different requirements of users. The socket connection between it and piping is quick and easy to install. At the same time, the hoisting cost is reduced and the installation speed is improved.
