A METHOD OF GROUND SOURCE CONSTRUCTION FOR PUTTING PE PIPE IN BOREHOLE WITH SPACER AND PACKED BETONITE IN WATER-SOLUBLE POLYMER

摘要

PURPOSE: A construction method of simultaneously adding bentonite and a PE pipe is provided to prevent the pump of grouting equipment from becoming clogged when bentonite is added since the bentonite is buried with a heat exchanger and thus is inflated by the water. CONSTITUTION: A construction method of simultaneously adding bentonite and a PE pipe comprises a bore(1), a 25mm PE heat exchanger(2), an inlet port(3), a water soluble polymer powder bag(4), a spacer(5) and a vent(7). If the water is added through the inlet port, the water soluble polymer powder melts in the water and the bentonite and the water make contact and thus the bentonite is inflated. The water soluble polymer powder bag is filled with the bentonite. The spacer makes the PE pipe heat exchanger maintain a straight line. The space is connected to the bentonite-filled polymer bag.
