WANG JIANGTAO / MO JIANHUA / WANG WANCHUN / YE XUEYUN / WANG ZHAORUI

The invention relates to the technical field of prefabricated concrete inspection wells, in particular to a prefabricated concrete inspection well and pipeline flexible connecting structure which comprises a prefabricated concrete inspection well, a prefabricated concrete short pipe and an inspection well sealing rubber ring. A round preformed hole is formed in the inner side of the prefabricated concrete inspection well body, a prefabricated concrete short pipe is installed on the inner side of the round preformed hole through an inspection well sealing rubber ring, inner surface protruding ridges are arranged on the periphery of the inner surface of the inspection well sealing rubber ring, and outer surface protruding ridges are arranged on the outer surface of the inspection well sealing rubber ring. According to the prefabricated concrete short pipe and the prefabricated concrete inspection well, in the installation process, the prefabricated concrete short pipe and the prefabricated concrete inspection well can be connected easily through the cooperation of the press-fit device, and meanwhile the prefabricated concrete short pipe and the prefabricated concrete inspection well can be connected conveniently through the deformation quantity of the sealing rubber ring. And the sealing performance of the prefabricated concrete short pipe can be ensured by the inclined surface of the end of the prefabricated concrete short pipe.

本发明涉及预制混凝土检查井技术领域，尤其为一种预制混凝土检查井与管道柔性连接结构，包括预制混凝土检查井、预制混凝土短管和检查井密封胶圈，预制混凝土检查井包括预制混凝土检查井主体，预制混凝土检查井主体内侧开设有圆形预留孔，圆形预留孔内侧通过检查井密封胶圈安装有预制混凝土短管，检查井密封胶圈内表面周围设有内表面凸脊，检查井密封胶圈外表面设有外表面凸脊，内表面凸脊和外表面凸脊一侧固定连接有外法兰，本发明中，在安装的过程中配合压配合装置能够使预制混凝土短管和预制混凝土检查井之间的连接工作变得容易，同时通过密封胶圈的形变量，以及预制混凝土短管端头斜面可以确保预制混凝土短管密封性。
