首先，施工前需要仔细检查铝合金衬塑管是否存在裂纹、变形等质量问题，确保管道无缺陷。在接头处需要采用相关的接头件，严禁使用过大或过小的接头，同时避免在接头处过度拉伸塑料管导致脆裂。

　　First of all, it is necessary to carefully check whether there are cracks, deformation and other quality problems in aluminum alloy lined plastic pipe before construction to ensure that the pipe is free of defects. It is necessary to use the relevant joint at the joint, it is strictly forbidden to use too large or too small joint, and avoid overstretching the plastic pipe at the joint to cause embrittlement.

　　拧紧螺纹应力要适当，不应过度。同时，管道与管道之间的接口应尽量减少，保证管道的整体性和不漏水性。需要注意管道的支撑和固定。

　　Tighten the thread stress properly and should not be excessive. At the same time, the connection between the pipeline and the pipeline should be reduced as much as possible to ensure the integrity and non-leakage of the pipeline. Attention should be paid to the support and fixation of the pipe.

　　在管道悬挂和支撑的地方，应当使用专用的管架和吊顶，并且定位准确，以确保管道的垂直度和水平度。铝合金衬塑管的埋地敷设需要预留一定的张力余量，以防止因地面沉降等原因产生管道变形。

　　In the place where the pipe is suspended and supported, a special pipe frame and ceiling should be used, and the positioning shall be accurate to ensure the verticality and level of the pipeline. The buried laying of aluminum alloy lined plastic pipe needs to reserve a certain tension margin in order to prevent pipeline deformation due to land subsidence and other reasons.

　　总之，铝合金衬塑管在施工过程中需要注意多个方面，并严格按照相关要求操作在进行对接前，需要先清除连接口的杂物和灰尘，以确保热熔连接的质量。然后再进行加热和对接，对接成功后需要立即采用专业的工具压实接口，在接口压实适当之后，冷却后即可在正常使用。
