The main methods for embedding channels are as follows:
Open cut method: This is the most common method of pre buried channels. Firstly, excavate a trench along the pipeline route, then place the pipeline into the trench and backfill it with sand, gravel or soil. This method is suitable for most situations, with simple construction and low cost.
Underground excavation method: This method involves directly burying pipelines underground without excavating trenches. The underground excavation method is usually used in situations where the burial depth is large or the surrounding environment is complex, and the construction difficulty is high, but it can reduce the impact on the ground.
Pipe jacking method: Dig a vertical shaft above the pipeline, then place the pipeline into the shaft and use a pipe jacking machine to push the pipeline underground. This method is suitable for situations with deep burial or complex geological conditions, and can reduce damage to the ground.
Method for reserving pipeline openings and pipeline sleeves: Draw an opening diagram before construction, perform opening positioning and technical review, and then install sleeves. This method ensures the accuracy of the hole location and size.
Pre embedding of waterproof conduit: Produce waterproof conduit according to design requirements, and perform positioning, fixation, and technical review. The material, specifications, and dimensions of waterproof conduit must comply with standards to ensure that it is flush with the wall or at a certain distance above the floor finish.
