The curtain grouting project for the dam of Xiaolangdi Multipurpose Project is large in size, big in difficulty, complex in geological conditions and high in technical requirements. In the grouting construction, the construction unit has made full use of the successful construction methods at home and abroad, and combined the foreign advanced construction technologies with the domestic matured construction techniques to form a series of perfected grouting techniques. The new techniques and technologies such as stable grouting slurry production, GIN grouting method, grouting monitoring and automatic recording have been developed and introduced. Some construction tools or devices have been developed and improved, such as hydraulic and pneumatic packers, and the pressure and discharge monitors used in the grouting supervisory system. All these advanced techniques and tools have wide application and popularization value. The construction technologies of curtain grouting for the dam of Xiaolangdi Multipurpose Project have provided new way of the development of grouting technology in our country.
