为实现雨水口井施工的机械化和装配化,加快施工进度,提高工程质量,解决现场用砖砌筑雨水口井的笨重劳动(如用砖砌雨水口井,勾缝有时要人工爬在地上工作)。由市政工程管理处和市政工程研究所,在市政设计院的协助下,有关人员于1980年研究试制了三种预制装配式混凝土雨水口井。这几种装配式雨水口井由市政处芦沟桥构件厂 In order to realize the mechanization and assembly of rainwater well construction, speed up the construction progress, improve the quality of the project, and solve the heavy and laborious work of building rainwater wells with bricks (such as using brick rainwater wells, and sometimes work to work on the ground manually) ). With the assistance of the Municipal Design Institute and the Municipal Engineering Management Office and the Municipal Engineering Research Institute, the relevant personnel studied three types of prefabricated concrete rainwater wells in 1980. These types of fabricated rainwater wells are prepared by the municipal office Lugouqiao Component Factory
