Heat transfer pipe embedded in a prefabricated pipe pile and embedding method

摘要

A heat transfer pipe embedded in a prefabricated pipe pile and embedding method, the heat transfer pipe comprising: several prefabricated pipe piles (2) arranged side by side, a heat transfer pipe module and a pump apparatus group (9). A base portion of the prefabricated pipe pile (2) is sealed by closing the bottom thereof. Inclined holes are provided at both sides of a top portion of the prefabricated pipe pile (2). A locking pin (6) is provided at an inner wall of the pipe pile. A steel plate (7) is provided on the locking pin (6). A steel bar structure is bound on the steel plate (7). The heat transfer pipe module comprises a horizontal heat transfer pipe (1) and a vertical heat transfer pipe (4). One end of the horizontal heat transfer pipe (1) communicates with the vertical heat transfer pipe (4). Another end of the horizontal heat transfer pipe (1) connects to the pump apparatus group (9). Another end of the vertical heat transfer pipe (4) also connects to the pump apparatus group (9). The horizontal heat transfer pipe (1) is embedded and fixed via the steel bar structure. An embedded portion of the vertical heat transfer pipe (4) passed through the inclined holes and via a steel bar bracket is fixed in the prefabricated pipe pile (2). The mode of connection of the heat transfer module in each prefabricated pipe pile (2) comprises a serial and a parallel connection. The required costs for manufacture and embedding are low, the engineering efficiency is high, and the survival rate of the embedded pipes is high.
