12. After the acceptance of water and electricity is qualified, it is acceptable to use a 1:3 cement mortar to fill the density (it should be divided into two levels of powder wall).
Hydropower installation budget
Hydropower installations occupy a large part of the installation of civil buildings. The installation project budget is a professional, knowledgeable and policy-oriented job. It not only has to master certain pre-clearing expertise and relevant national policies and regulations, but also understands the basic knowledge of related majors, design and construction methods, procurement of materials and equipment, and investment control.
