《电工技术》编辑部:我是江西省棉花研究所的一名电工,在照明电气安装施工中,我深深感到预埋件如果预埋不好,对电气安装工作是一个很大的困难。特别是对新建房屋工程如果预埋工作跟不上,则要用人力去打混凝土(或墙)洞来埋置预埋件,这样增大了工程量,工效低,而且也不经济,同时对建筑物也有一定程度的损坏。 “Electrical Engineering” Editorial Department: I am an electrician of the Cotton Research Institute of Jiangxi Province. During the installation of lighting electrical equipment, I deeply felt that if the embedded parts were not embedded well, it would be a great difficulty for the electrical installation work. In particular, if the newly built housing project fails to keep up with the pre-buried work, it will be necessary to use human power to play concrete (or wall) holes to embed the embedded parts. This increases the amount of work, has a low work efficiency, and is not economical. The building also has some degree of damage.
