Upward pressing and downward hanging combined water pressure method prepressing and construction method for movable formwork
The invention discloses an upward pressing and lower hanging combined hydraulic method prepressing and construction method for a movable formwork, which comprises the following steps of: laying a plurality of sand bags on the top surface of the movable formwork, and hanging a plurality of water bags on the bottom surface of the movable formwork to form the upper pressing and lower hanging combined hydraulic method; and pre-pressing and unloading the movable formwork through the upper-pressing and lower-hanging combined hydraulic method, and carrying out settlement observation on the movable formwork in the pre-pressing and unloading process to obtain observation data. The upper pressing and lower hanging combined water pressure method is matched with the movable formwork to eliminate inelastic deformation of the movable formwork under the condition of meeting safety and economy, the elastic deformation value of the movable formwork is more accurately measured, whether the whole movable formwork meets the safety requirement is verified, meanwhile, the water bag and the sand bag can be repeatedly utilized, the construction cost is reduced, a water pump is used for filling and draining water for each sealed water bag, so that the safety risk of hoisting is reduced.
本发明公开了一种用于移动模架上压下挂组合水压法预压及施工方法，包括以下步骤：在移动模架顶面铺设多个砂袋，同时在移动模架底面挂载多个水袋，形成上压下挂组合水压法；通过所述上压下挂组合水压法对移动模架进行预压和卸载处理，在预压和卸载的过程中对移动模架进行沉降观测，得到观测数据。本发明通过上压下挂组合水压法配合移动模架在满足安全、经济的情况下消除移动模架的非弹性形变，更精准的测出移动模架的弹性形变值，验证了移动模架整体是否满足安全要求，同时可多次反复利用水袋和砂袋降低了施工成本，通过水泵为各密封水袋进行灌水、放水作业，降低了起重吊装的安全风险。
