Problems solved by technology
[0006] To sum up, in the traditional construction process, operators invest more, the number of formwork turnover is limited, the scaffolding increases with the increase of construction height, the investment of construction raw materials is relatively large, and the next layer can only be poured after the concrete is poured. The construction progress is slow. After the construction is completed, due to the joint problem of the concrete construction joint surface, it is easy to produce quality defects such as misalignment and grout leakage.

Embodiment Construction
[0053] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Such as Figure 1 to Figure 5 middle,
[0054] The "open"-shaped elevating frame 1 is a structural form of the sliding template body, and the "open"-shaped elevating frame 1 is the main component that jacks are installed and connected with the enclosure and the template as a whole. The main function of the lifting frame is to control the displacement and deformation of the formwork and enclosure due to the lateral pressure and impact force of the concrete; at the same time, it bears the vertical load acting on the entire formwork and transmits the above load to the jack and the support rod. When the hoist is working, it drives the enclosure, template and operating platform to slide upward together.
[0055] The enclosure truss beam 2 is used to reinforce the sliding formwork panels so that the formwork has sufficient rigidity and stability. Its main f...

The invention discloses a hydropower station rectangular high tower hydraulic climb slip form system and construction method; the system comprises a Chinese character Kai-shape lifting rack, an enclosure truss girder, a F-type lifting rack, jacks, templates, [phi] 48 climb poles, auxiliary disc hooks, 5cm thickness riding track plates, auxiliary discs, maintenance water pipes, to-be-casted concrete, casted concrete, demoulded concrete, a maintenance gate slot, and a gate body; the method comprises the following steps: 1, slip form bodies are processed in a factory to form module members, the members are assembled on site, and the length and weight of the members are proper to transport; 2, module support platform construction; 3, module assembling order. The advantages are that the hydropower station rectangular high tower hydraulic climb slip form system can realize contentious construction, is fast in speed, simple in structure, saves template making quantity, reduces safety troubles, and reduces safety cost.
Description
technical field [0001] The invention relates to a hydraulic climbing sliding form system and a construction method for a rectangular high tower of a hydropower station, and belongs to the technical field of hydropower station construction. Background technique [0002] At present, for vertical reinforced concrete structures, according to the traditional construction technology during construction, the height of each pouring is 2.0-4.0m, and the formwork usually adopts large steel formwork, composite steel formwork, and bamboo plywood formwork. [0003] For example, the patent application number CN201010546376.4 discloses a reliability analysis method for a wind power generation high tower system, which includes the following steps: selecting the external load random parameters of the wind power generation high tower; selecting or generating external loads corresponding to the random parameters; Load; establish the shell element model of the wind power tower system in the ANS...
