the construction of hydraulic engineering has always been an item of great importance to the country , with the advent of the new century countries have invested a lot of manpower and resources to carry out hydraulic workers Construction , to make water conservancy projects in flood control , play a positive role in drinking water irrigation, etc. . The construction of Water Conservancy project needs to start from many aspects. And it runs through the construction cycle of the Whole Water Conservancy project to ensure the construction quality of Water Conservancy project . Lining concrete technology is a kind of application in the construction of Water Conservancy channel. Technical , through the application of lining concrete technology, it can enhance water conveyance capacity of water conservancy channel and greatly enhance the service life of hydraulic engineering. .

describes the principle and function of wet shotcrete construction technology , from raw material selection and concrete mix control two aspects analysis of wet-sprayed concrete raw material control side method , Research on application of wet shotcrete technology in tunnel construction , including pre-construction preparation ,wet shotcrete Construction Technical essentials , and propose wet shotcrete Construction Notice , to ensure the construction quality of the tunnel works .

Fiber composite polymer has been widely used to structure Reinforcement to civil Engineering and Architecture because a its light weight, high strength, corrosionresistance , Fatigue resistance , Damping performance etc . Based On the about [ Progress to composites reinforced Concrete technology,this paper discussed This Constitutive model of reinforced Concrete then Ultimate bearing capacity, the The durability, the earthquake resistance To the reinforced concrete Structure and The mechanism in fiber Composites reinforced Concrete structure . Finally polyurea elastomeric Coating as a new Reinforcement material was introduced In This paper , whichcan effectively Improve the bearing capacity , The durability and this Earchquake resistance of the reinforced Concrete structure .

The purpose of this paper is to analyze and discuss the technology of clear concrete , and quality control of clear-water concrete for a referral , for reference only .
