随着建筑业的发展和现浇主体工艺的广泛使用，对安装工程预留工艺也提出了新的要求。传统的安装工程预留工艺的作法是多种多样的：有的是直接预埋永久性套管；有的预埋木材或铁皮做的模具；有的被埋丙。烯泡沫块；有的预埋竹筒；还有的预埋红砖或加气砖。这些作法虽各有所长， With the development of the construction industry and the widespread use of cast-in-place main processes, new requirements have also been put forward for the installation engineering. There are many ways to set aside a traditional installation process: Some are directly embedded in permanent casing; some are made of wood or metal sheet; some are buried. Efficient foam blocks; embedded bamboo tubes; and embedded bricks or bricks. Although these practices have their own strengths,
