Prefabricated concrete well internode connecting structure and construction method thereof
The invention discloses a prefabricated concrete well section connecting structure which comprises a first well section, a second well section arranged on the first well section, a well lid arranged on the second well section and a ladder stand arranged on the first well section and the second well section and comprises a connecting notch and a connecting structure. The connecting structure is arranged at the connecting notch and used for connecting the first well section and the second well section. According to the connecting structure between the prefabricated concrete well sections, a new tongue-and-groove butt joint mode is adopted, the self water blocking effect of the connecting notches is enhanced through gap meshing, the water swelling rubber water stop strips are arranged in the connecting notches, the waterproof effect is further enhanced, meanwhile, asphalt sealant is smeared on the inner construction joints and the outer construction joints of the well sections, and the direct waterproof effect is achieved; and after the well sections are installed in place, annular rake nails are arranged outside the well sections, the well sections are effectively restrained, and the integrity of the shaft is enhanced.
本发明公开了一种预制混凝土井节间连接结构，包括第一井节，设置于所述第一井节上的第二井节，和设置于所述第二井节上的井盖，以及设置于所述第一井节和所述第二井节的爬梯，包括：连接缺口和连接结构，连接结构设置于所述连接缺口处，用于将所述第一井节和所述第二井节连接。该预制混凝土井节间连接结构，采用一种新的企口对接形式，通过缝隙咬合，加强连接缺口的自身阻水效果，在连接缺口内部设置遇水膨胀橡胶止水条，进一步增强防水效果，同时在井节内外施工缝部位涂抹沥青密封膏，起到直接防水效果，井节安装就位后在外部设置环向耙钉，对井节之间进行有效约束，增强井筒的整体性。
