Design of Hydraulic Structures
During the design of small hydropower plants, the main stage of engineering work is the design and working documents. The expanded format of the proposed documents can be submitted as follows:
- General layout solutions;
- Technological solutions;
- Constructive solutions;
- Environmental assessment;
- Feasibility study.
Design of dams
Earth dams are the most common hydraulic structures. They make it possible to block the flow of water (river or stream) and ensure minimal costs by using relatively simple technologies.
Concrete dams are one of the most common hydraulic structures we use to block rivers. As a rule, a concrete dam is designed in the absence of ground materials (for an earth dam), or if the river valley is quite narrow.
The main stages of design and calculations are:
- Connecting the dam to the foundation
- Comparison of the core and screen of an earth dam
- Filtration strength of the dam core
- Dam crest
- Berms
- Galleries in the body of a concrete dam
Design of water intake and spillway structures
- Tower spillway
- Stepped spillways
- Floodgates and water passages
- Conjugation of spillway edge with tail water
- Spillway apron
Design of other hydraulic structures
- Fishway
- Cesspool
- Retaining walls
- Coast guard structures
- Waterproofing structures
- Waterproofing of collectors and tunnels
- Waterproofing of deformed joints
- Waterproofing during the reconstruction of structures
