Abstract:

The traditional construction technology of concrete sliding formwork is mainly applied to the circular silo structure and circular vertical shaft structure. As for the construction of the lining structure of the rectangular shaft, in order to guarantee the construction quality, sense quality, structural waterproof and construction of the concrete structure, and to reduce the risk of water leakage induced by dislocation of formwork joint, the sliding formwork system is studied from the aspects of design and application of sliding formwork technology in rectangular vertical shaft based on existing experience, scheme argument and the characteristics of rectangular vertical shaft structure and its cross-section. The study results show that the rectangular sliding formwork construction method is obviously superior to the conventional combined formwork construction method, which can effectively reduce the construction schedule, rapid the construction progress, ensure the concrete quality and visual quality, improve the quality of vertical shaft construction, and reduce the risk of construction safety.

Key words: rectangular vertical shaft, lining structure, sliding form construction technology
