Embodiment 2
[0048] Embodiment 2, build a height and be 18 meters small-diameter observation wells,
[0049] 1. Formwork production, according to the height of the observation well and the height of each concrete pouring, design a reasonable size of the shaped steel formwork. In the case of this construction method, the observation well is 18m, and the shaped steel formwork is processed to 6m, which can be used for turnover. According to the standard modulus, each section is 1.5m, and the inner and outer steel formworks each need 4 sections. According to construction experience and related calculations, the inner and outer steel formwork panels are made of 5mm thick steel plates, the longitudinal and transverse reinforcement ribs are made of 10×80 ring-shaped steel plates, and the bolt holes of the formwork connecting flanges and longitudinal connecting plates are M20 high-strength Bolt preparation. Each section of outer steel formwork is composed of 2 semi-circular arc steel formworks. ...
