B, start high-pressure injection pump, when carrying brill, carry out the high pressure jet grouting of clear water or cement-based grout with the pressure of 20 1 40MPa in the bottom of anchor hole, to designing requirement, and drilling rod and drill bit are withdrawed from anchor hole gradually with the diameter that enlarges the anchor hole bottom;
C, utilize isolation locating rack (8) to install Grouting Pipe (2), feed tube (5) and drain pipe (6) to be connected, allow the bottom of Grouting Pipe (2) pass swelling heat exchanger (7) along axis direction, again swelling heat exchanger (7) is wrapped on Grouting Pipe (2), forms an anchor hole plug-in unit;
D, the anchor hole plug-in unit is inserted into design attitude in the anchor hole slurries along anchor hole, by feed tube (5) to the interior pressure injection entry of swelling heat exchanger (7) or contain the water of antifreezing agent, swelling heat exchanger (7) is expanded, then shutoff is carried out at the two ends of feed tube (5) and drain pipe (6), to prevent that mud from entering in pipe, keep simultaneously swelling heat exchanger (7), feed tube (5) and the interior water of drain pipe (6), swelling heat exchanger (7) during with assurance slip casting, feed tube (5) and drain pipe (6) are indeformable,
E, backfill is pressed in anchor hole from bottom to top from the anchor hole bottom by Grouting Pipe (2) with grouting pump or slush pump, carries out slip casting in anchor hole, until fill with whole anchor hole.
10. the job practices that the ground source heat with swelling heat exchanger as claimed in claim 9 can anchor pole, it is characterized in that: the high pressure jet grouting method in described step B can adopt single pipe method or dual pipe method or tri-tube method or multiple pipe method, and the aperture of described anchor hole is 120-300mm; Also comprise in described step C and utilize isolating frame that connection is installed anchor bar steel twisted wire (3) or band sleeve pipe reinforcing bar; Grouting Pipe in described step e (2) slip casting on one side promotes it on one side; Also be included in described step e horizontal feed tube (15) and horizontal drain pipe (16) are set in bed course (11), the import of described feed tube (5) is connected with the outlet of horizontal feed tube (15), and the outlet of described drain pipe (6) is connected with the import of horizontal drain pipe (16).
