Static drill rooted energy pile and production method and construction method thereof

Abstract

The invention provides a static drill rooted energy pile and a production method and a construction method thereof. The static drill rooted energy pile comprises a pile body, wherein a heat exchangingpipe is pre-buried in a concrete pipe wall of the pile body; joints are reserved at the two ends, close to the pile body, of the heat exchanging pipe; pile extension connection is realized between the pile bodies through a sleeve; when pile extension is carried out, the sleeve are arranged outside the two pile bodies in a sleeving manner; and the heat exchanging pipe joint at the end part of thepile body is connected with the heat exchanging pipe joint corresponding to the end part of the other pile body, and the connecting structure of the two heat exchanging pipe joints is positioned on the outer side of the pile body. The static drill rooted energy pile has the advantages of improving the durability and the construction efficiency of the heat exchanging pipe, being reliable in connection between piles, ensuring the bearing capacity of the energy pile and being stable in working.

Description

technical field [0001] The invention belongs to the technical field of ground source heat pump pile foundation buried pipes, and relates to a static drilling and rooting energy pile, a production method and a construction method thereof. Background technique [0002] With the rapid development of human society, energy consumption is also increasing, and it is imperative to develop new energy sources. Geothermal energy is gradually replacing traditional energy sources through ground source heat pump technology in building heating and cooling due to its environmental friendliness. The temperature of geothermal energy at a certain depth under the surface remains constant all year round. It is lower than the outdoor temperature in summer and higher than the outdoor temperature in winter. The ground source heat pump transfers the heat generated in the building to the soil through the exchange medium in summer, and transfers the heat to the soil through the exchange medium in wint...

AI Technical Summary

Problems solved by technology

[0007] In the domestic field test research on the thermal response of static drilling and rooting piles, the heat exchange tubes in different arrangements are bound and fixed on the side walls of the prefabricated pipe piles, and then sink together with the piles in the cement soil. The heat exchange tubes are welded and connected, and the construction is relatively simple, but the heat exchange tubes and joints on the pile side are also easily deformed and damaged during on-site construction, which affects the working quality of the entire ground source heat pump system, and the construction efficiency is not high

[0008] In summary, in order to solve the problems of traditional pile-to-pile connection, heat exchange tube embedding, joint damage, and energy pile bearing capacity, it is necessary to design a pile-to-pile system that can improve the durability and construction efficiency of heat exchange tubes. The connection between the piles is reliable, the bearing capacity of the energy pile is guaranteed, and the new energy pile works stably
