Description
Technical field
The present invention relates to a kind of hydraulic engineering field, and in particular to a kind of production method of water channel gool prefabricated component.
Background technology
Water channel is the main tool of the filling such as irrigation and water conservancy, traffic, municipal administration, sewage, rainy day draining row's engineering, and concrete
The U-shaped gool mould of soil is one of main tool for producing gool.
With greatly developing for China's modern agriculture and water resource infrastructure, country and place are built to agricultural and water conservancy basis
If scale of investment it is increasing.China is one to the relatively backward country of agricultural technology, vast in territory, water resource assignment ten
Divide inequality, it is particularly very in short supply to west area, the water resource of drug in some provinces.At the same time, due to filling row's mode and material
It is unreasonable, great lot of water resources is not utilized and protected well, is had become in China's agriculture project and water conservancy construction
The poorly efficient serious problems utilized of water resource.Over more than 20 years, precast concrete gool（Referred to as U-shaped gool）It is special in China each province and city
It is not popularization and application in western water resources regional agricultural water conservancy project in short supply, it is agriculture abundant with hydraulic department has obtained various regions
Certainly, significant economic benefit and social benefit are achieved.
Also there is many through retrieving the Chinese patent literature about water channel gool prefabricated component, it is as follows：
