The invention relates to a deep pit tube formwork anti-floating reinforcement system and a construction method thereof. A formwork structure is supported in a deep pit, an accommodating space is reserved for the formwork structure, and a tube formwork is arranged in the accommodating space. The deep pit tube formwork anti-floating reinforcement system is characterized by comprising a press beam arranged at the top of the tube formwork, wherein two ends of the press beam extend out of the tube formwork and are fixed to the formwork structure through fixing parts. According to the deep pit tube formwork anti-floating reinforcement system, the press beam is arranged on the tube formwork in a pressed mode and is fixed to the formwork structure by utilizing the fixing parts, accordingly the tube formwork is limited in the formwork structure by the press beam, the influence of a buoyancy force on tube formwork positioning is effectively offset, and the technical problems of floating and deviation of the tube formwork are solved.
Description
technical field [0001] The invention relates to the field of building construction, in particular to an anti-floating reinforcement system and a construction method for a deep pit barrel form. Background technique [0002] In the field of building construction, super high-rise buildings are designed with deep foundation pit elevator shafts, water collection wells and other structures. However, in the process of concrete construction, the cylinder formwork in the deep foundation pit is often due to its large volume and the large buoyancy generated by the concrete, which will cause problems such as floating or misalignment of the cylinder formwork, which will cause the concrete in the elevator shaft of the deep foundation pit after the formwork floats up. The molding size will have a large deviation from the drawing, which will greatly increase the cost of labor and materials caused by rework. Contents of the invention [0003] The purpose of the present invention is to ove...
