Embodiment Construction
[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only some embodiments of the present invention; rather than all embodiments. Based on the embodiments of the present invention; all other embodiments obtained by persons of ordinary skill in the art without creative work; all belong to the protection scope of the present invention.
[0034] Such as Figure 1 to Figure 5 As shown, the present invention takes Rwanda’s Gorsaha swamp improvement project as an example. The curved overflow surface 2 of the project is divided into 6 positions, which are 1#~6# from left to right, and the overflow top elevation is 1166.92 m, the bottom elevation is 1162.41m, the height difference is 4.51m, the length of the overflow surface 2 is 11m, the minimum radius of the overflow surface 2 arc is 2...

The invention belongs to the technical field of water conservancy and hydropower construction, and relates to a construction method for a curved overflow surface of reinforced concrete with a special-shaped formwork. The overflow surface is poured in several continuous bins; the method includes the following steps: making a special-shaped formwork; Install templates and waterstops on both sides of the warehouse where the surface is located; bind steel bars on the overflow surface on the foundation of the warehouse, and the bending curve of the steel bars is the overflow curve; fix special-shaped formwork on both sides of the warehouse; Leveling; Concrete on the overflow surface is poured layer by layer between the special-shaped formwork, and the reinforcement on the overflow surface is poured into the concrete; the overflow surface is plastered and maintained. Under the condition of limited construction conditions, common wooden formwork can be used to process it into a special-shaped wooden formwork that can be simple, efficient, and cost-effective. It saves costs while ensuring the quality of the project. Efficient construction also achieves the sliding formwork Engineering quality during construction; this special-shaped wooden formwork is easy to make and can be used repeatedly.
Description
technical field [0001] The invention belongs to the technical field of water conservancy and hydropower construction, and in particular relates to a construction method for a curved overflow surface of reinforced concrete with special-shaped formwork. Background technique [0002] The traditional domestic overflow surface pouring technology is slip-form construction, which has fast construction speed and reliable quality. However, due to the technical limitations of some foreign countries, and the structural design of the overflow surface, it is very difficult to realize slip-form construction, and the input cost is also high. increase. Therefore, a simple construction method can be adopted, using special-shaped formwork to control the shape and elevation of the overflow surface, and adopting the method of pouring the overflow surface in separate bins. On the premise of ensuring the quality and progress, the construction cost can be greatly saved. [0003] In the field of w...
