The invention discloses a phase change expansion and shrinkage drawing pore-forming pipe and a pore-forming method, and the pore-forming pipe comprises an air expansion outer pipe body, a phase change material filled in the air expansion outer pipe body, and a heat transfer cable penetrating through the phase change material. During pore-forming, various pore-forming specifications required in engineering are formed by adopting the inflatable outer pipe body and the phase-change material, and after pore-forming is completed, the inflatable outer pipe body and the phase-change material can be recycled and reused, and the inflatable outer pipe body and the phase-change material are repeatedly utilized, so that material waste caused by pore-forming is greatly reduced, and the repeated utilization rate of the pore-forming material is increased; and the engineering cost is reduced, and the engineering construction cost is saved.
本发明公开了一种相变胀缩抽拔造孔管及造孔方法，该造孔管，包括气胀外管体、填充在气胀外管体内的相变材料以及穿过相变材料的传热电缆。造孔时，通过采用气胀外管体和相变材料，形成工程中需要的各类造孔规格，造孔完成后，气胀外管体和相变材料可回收再次利用，气胀外管体和变相材料的重复利用，大大减少了由于造孔导致的材料浪费，提高了造孔材料的重复利用率，降低了工程造价，节约了工程建设成本。
