2), existing PE heat exchange of heat pipe buried in silt, and major part is arranged in building basement, does not possess recoverability；
3), under the conditions of existing heat exchanger group hole, it is easily generated cold heat accumulation, long-lasting, the rare research of stability of system；
4), building bottom and surrounding intensive cloth hole, boring ratio ground is deep, and, layout is without the PE flexible pipe of rigidity in the hole in, and the impact of foundation structure is required study by it；
5), numerous dense arrangement, do not consolidate the boring of filling, supporting course shear resistance will be had a strong impact on；
6), tradition PE heat exchange of heat pipe, the problems such as the poor heat exchange area contacted with ground of heat exchanger tube heat conductivility is little, pressure-bearing is little；
Due to above-mentioned technical bottleneck so that more than 70% new building does not possess the condition using this technology, old building transforming is more difficult to use, and the popularization and application to ground source heat pump technology form serious hindrance.
