Description
Technical field
The invention belongs to the lossless method increased of existed concrete bridge water gate.
Background technology
Concrete gate is cheap, and processing is easy with maintenance, and many regulating dam type plants without storage are all happy at present
Using the structure of this kind of concrete gate is：Stoplog type groove profile concrete gate door board is connected by consolidating steel plate strip from bottom to top
Being connected on the inside of gate, gate has support arm to connect each door-plate, and the height of the support arm is higher than the height of door-plate.Because engineering operation will
Ask, igfet gate can not meet head requirement, output of hydraulic turbine is affected, it is therefore desirable to increase.With metal structure gate phase
Than, concrete gate can not be welded directly, other directly modes of increasing are required for cutting concrete gate door,
The problems such as welded reinforcement, second stage concrete, both existed and the formation of former gate structure had been damaged, and also influenceed the operation of sluice.
The content of the invention
