Embodiment Construction

[0040] Please refer to the attached figure 1 to attach image 3 As shown, the present invention is a method for determining the size of the inner formwork of a circular platform hydraulic structure, which includes determining the height h of the concrete inner formwork and determining the length of the concrete inner formwork.

[0041] Wherein, the method for determining the height h of the inner formwork in the concrete is as follows:

[0042] The volume of concrete poured during this period is equal to the volume of concrete construction that the formwork can protect: since only one concrete pouring equipment is used, the part with the largest volume of concrete is located at the uppermost part of the structure, that is, the place with the largest radius ;have to

Abstract

The invention relates to a circular truncated cone hydraulic structure inner formwork size determination method. According to the method, a circular truncated cone hydraulic structure inner formwork size calculation method is given, and the problem that reasonable calculation of formwork size is not available at present is solved; formwork size design is optimized, so that the formwork size is more reasonable, and construction is more convenient. Through practical engineering application, the calculation method is accurate and efficient, and the blank of the project in China is filled up.

Description

[0001] 【Technical field】 [0002] The invention relates to a method for determining the size of a formwork, in particular to a method for determining the size of a formwork in a circular platform hydraulic structure, and belongs to the technical field of construction engineering. [0003] 【Background technique】 [0004] At present, there is no unified method for determining the size of the internal formwork of large-area curved shell hydraulic structures, and it is impossible to give a determination method for the internal formwork from the perspectives of the initial setting time of concrete, the error requirements of concrete flatness, and the convenience of construction and resource conservation. Unnecessary waste of resources. [0005] Therefore, in order to solve the above technical problems, it is indeed necessary to provide an innovative method for determining the size of the formwork in the circular platform hydraulic structure, so as to overcome the defects in the prio...
