Embodiment Construction

[0038] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The protection scope of the present invention is not limited only to the description of this embodiment.

[0039] Such as Figure 1-Figure 10 As shown, a prefabricated energy pile is composed of a prefabricated pile body 8 , a prefabricated pile can 9 and a prefabricated pile cap 11 . The outer surface of the prefabricated pile body 8 is polygonal, and the inner surface is polygonal or circular. The reinforcement cage in the prefabricated pile body 8 is composed of hollow steel pipes 3, solid steel bars 4 and stirrups 5. The heat transfer tubes 6 are arranged in the hollow steel pipes. 3; the heat transfer elbow 7 and the heat transfer pipe joint 10 are pre-embedded in the prefabricated spud can 9; the heat transfer elbow 7 and the heat transfer pipe joint are pre-embedded in the prefabricated pile cap 11 in the form of a W-shaped heat transfer...

Abstract

A construction method for a precast energy pile is characterized in that a heat transfer tube is embedded into a hollow steel tube, the hollow steel tube replaces a traditional solid reinforcement and serves as a main reinforce ement of the precast pile, and for being connected with the heat transfer pipe in the precast pile, a heat transfer elbow and a heat transfer tube joint are embedded into a precast pile shoe and a precast pile cap. As the heat transfer tube is embedded into the hollow steel tube, the technical problems of mutual interference, poor concrete compactness, reinforcement corrosion, effect on the overall bearing capacity of a pile foundation and the like caused by binding and embedding of the heat transfer tube and the main reinforcement are effectively solved. Moreover, the embedded tube is higher in survival rate, a large number of piles are conveniently stacked and safely transported, construction period is short, and underground space and construction cost are saved.

Description

[0001] technical field [0002] The invention relates to the technical field of pile buried pipes of a ground source heat pump system, in particular to a construction method of a prefabricated energy pile. It is mainly applicable to the field of construction pile foundation and ground source heat pump technology. [0003] Background technique [0004] Ground source heat pump technology is a new technology that effectively utilizes underground renewable energy, which is of great significance to the national energy conservation and emission reduction strategy. This technology takes advantage of the relatively stable temperature characteristics of underground soil, surface water, and groundwater, and uses the earth as an energy storage body to exchange heat (transfer underground heat to the upper building in winter; store upper heat underground in summer). Air-conditioning system, which can replace traditional air-conditioning technology. Buried heat exchangers underground i...
