The invention discloses a construction method for embedding a pipe in a ground source heat pump pouring pile reinforcement cage. A steel pipe is used for substituting for a solid reinforcing steel bar as the main rib of a pouring pile reinforcement cage, and a heat transmission pipe is embedded in the steel pipe, as a result, problems caused by binding and embedding the heat transmission pipe and the reinforcement cage, including mutual interference, high probability of corrosion of a reinforcing steel bar, effect on overall bearing capacity of a pile foundation and the like, are solved. Compared with the traditional way of binding and embedding the heat transmission pipe and the reinforcement cage, the construction method is higher in survival rate of embedded pipe, compactedness of concrete is high, and embedment of the heat transmission pipe surely does not lower the overall bearing capacity of the pile foundation; compared with another traditional way of drilling and pipe embedding, the construction method greatly shortens construction period and saves underground space and engineering cost. The construction method is simple in construction process, strong in operability, convenient for quality control, and remarkable in economic benefit and heat transmission effect.
