保定泰鼎路桥工程有限公司，我司多年来与国内京石高铁、石太铁路、津秦铁路、沈丹铁路、沪昆高铁、郑徐高铁、南京高铁等国内多条高速公路，水利工程建设工作。
第一阶段产品为方型，顶部和底部略小，若是分开就是上下两个梯形。加工时先加工出来两个凹槽状的模型，再把它们合在一起，即成为一个成品。这种产品解决了传统产品不耐腐蚀，易渗漏堵塞的缺点，但是严密性还不够好，抗压性也一般，无法制作大型产品。
The first stage of product is the side, top and bottom is slightly smaller, if separate upper and lower two ladder. Two grooves are processed in the process of processing, and then they are combined together to become a finished product. This product solves the shortcomings of traditional products, such as no corrosion resistance, easy leakage and blockage, but the tightness is not good enough, and the compression resistance is also general, so it can not make large products.
第二阶段产品基本为横卧的圆柱体，但顶部和底部还是设计为平面。车轮状凹凸面封头开始使用。因为是筒状模具，这一阶段的产品一般采用对接的方法连接结合。这种产品的抗压性能要比第一阶段的好，但是产品的严密性还可以再加以改良，而且这种产品的加工程序复杂，不利于工厂化生产。
The second stage product for the horizontal cylinder, but the top and bottom is designed into a plane. The wheel - shaped concave convex head begins to use. Because of a cylindrical mold, the product of this stage is usually connected by a butt connection. This product has better compression performance than the first stage, but the tightness of the product can be further improved, and the processing program of this product is complex, which is not conducive to factory production.
第三阶段产品也叫手糊玻璃钢化粪池。这种产品保持了第二阶段的车轮状封头设计，筒体为圆筒状，基本上一次成型，但无层次工艺，很难同时满足制品对于强度和抗漏渗、防腐蚀的要求。
The third stage product is also called the hand paste glass steel septic tank. This product has maintained second stages of wheel shaped head design, the cylinder is cylindrical, basically once formed, but no level process, it is difficult to simultaneously meet the requirements for products for strength and anti leakage and corrosion protection.
第四阶段产品即为机械缠绕玻璃钢化粪池，这种产品筒体两端采用力学凹凸面设计制作，筒体采用机械缠绕工艺、高抗压结构设计制作，产品整体成型后抗压、抗冲击性强度以及韧性都比传统手糊玻璃钢化粪池的安全系数增加数倍，弥补了传统手糊玻璃钢化粪池、波纹型玻璃钢化粪池罐体手糊厚薄不均匀、制造粗糙等不足。
The fourth stage of the product is mechanical winding FRP septic tank, making mechanical design using this product both convex and concave cylinder, the winding process, high compressive mechanical structure design by cylinder, the overall molding products after the compressive strength, impact strength and toughness than the traditional safety coefficient hand paste glass reinforced plastic septic tank increases several times, make up the traditional hand lay-up FRP septic tank, corrugated glass steel septic tank tank hand uneven, rough manufacturing defects.
