The invention provides an implanted type regional underground water multielement information acquisition system loaded on a prefabricated tube pile and relates to the field of geotechnical engineeringfield test and monitoring. The system comprises a first prefabricated tube pile segment, a specially-made second prefabricated tube pile segment and a testing system, wherein the first prefabricatedtube pile segment is generated in engineering construction. Firstly, the testing system is prefabricated in the tube pile segments; the second prefabricated tube pile segment is in abutting joint withthe first prefabricated tube pile segment; and the prefabricated tube pile with the testing system is driven into an underground designated detection position at a designated position. Data acquiredby the testing system are transmitted to a ground radio transmitter through a data line and transmitted to relevant personnel for analysis. According to the system, the first prefabricated tube pile segment serves as a carrier; the second prefabricated tube pile segment is connected into the first tube pile segment; cast-in-place of the prefabricated tube pile is not needed; the environment is protected, and construction is conducted rapidly; hole drilling is not needed when underground water information is acquired; and information acquisition cost is lowered.
