Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and through specific examples. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0019] A construction method of a large-diameter circular hydraulic structure pool wall support system, the steps are:
[0020] Step 1: according to the design parameters of the drawing, determine the standard length of the standard section of the concave surface shaped square timber 1 of the standard curvature and the curvature of the curved surface 2, and the standard section length of the convex curved surface shaped square timber 4 and the curvature of the convex surface 3; In this example, the length of the 1 / 2 segment of the standard curvature shaped square timber is 3m, and the curvature of the concave surface is R 池 体外半径 = 13.45 meters, the convex surface curvature is R 池体内半径 = 13 meters, process...

The invention relates to a construction method of a large-diameter round hydraulic building pool wall support system. The method comprises the following steps that: according to drawing design parameters, processing is carried out after lofting; inner and outer pool wall bamboo plywood is erected and arranged inside and outside pool walls; vertical back beams made of steel pipes are uniformly distributed outside the inner and outer pool wall bamboo plywood at intervals; curve surface shaping square timbers are arranged on the outer sides of pool wall top opening templates arranged on the top of the steel pipe back beams, and in addition, the templates and the shaping square timbers are primarily fixed by self-tapping screws; a step-by-step tightening tool is used for reinforcing the outer sides of the shaping square timbers; and the support system is completed. A novel template combination mode is formed; the standard section length range of the standard curvature shaping square timbers is 1m to 4m; pine with low water contents is selected as the materials; the lofting is carried out according to the design curvature parameters; the problem of curved structure line style control is solved; and the construction quality is ensured, and meanwhile, the problem of higher cost of shaping steel templates is avoided.
Description
technical field [0001] The invention belongs to the field of construction, and relates to large-diameter circular hydraulic structures, in particular to a construction method for a large-diameter circular hydraulic structure pool wall support system. Background technique [0002] Large-scale hydraulic structures have various structures, and the large-diameter circular pool wall structure is one of the common types. Since the vertical surface of the pool wall is a curved surface, line shape control is the difficulty and focus of construction under the condition of meeting the waterproof requirements. At present, although the conventional steel formwork support system can meet the quality requirements, the cost is relatively high; the cost of the steel pipe wood formwork support system is relatively low, but there is a problem of poor top line control. [0003] By searching, no published patent documents identical with the application of the present invention have been found....
