Description
Technical field
The present invention relates to a kind of geothermal energy and utilize technology, be primarily adapted for use in the technical fields such as building pile foundation, especially
It relates to a kind of CCHP pile for prestressed pipe device and preparation method thereof.
Background technology
Shallow layer geothermal energy, has another name called shallow layer ground-temperature energy, belongs to low-grade renewable and clean energy resource, is current techniques economic condition
Under one of heat resource of earth interior possessing value of exploiting and utilizing most.During shallow layer geothermal energy is develop and useedd at present, mainly
It is the feature directly utilizing the long-term constant temperature of thin solum, utilizes heat pump cycle to reach surface structures heating in winter or summer
The effect of refrigeration.Ground source heat pump technology, belongs to one of most common form that shallow layer geothermal energy directly utilizes, and this technology utilizes underground
Soil, surface water, the metastable characteristic of subsoil water equitemperature, by with the earth for storage bodies carry out heat exchange can be again
The air conditioning system of the raw energy;This technical scheme can substitute traditional heating system such as conventional boiler or city planting ductwork and air-conditioning system
System, reaches the purpose of energy-saving and emission-reduction.Embedded underground heat exchanger tube, is construction Difficulties and the investment priority of ground source heat pump technology;And ground
Lower heat exchanger tube bury underground needs take bigger land area and the underground space, cause that its initial stage is buried underground wait construction cost height, thus
Affect the application of its large-scale popularization.By the underground heat exchange pipe burial and construction in ground source heat pump technology and traditional architecture pile foundation construction phase
In conjunction with, construction procedure and the underground heat exchange pipe that can effectively solve special pipe laying take underground space problem, thus are greatly saved
Construction costs;Based on this underground buried tube form formed the piling strtucture with underground heat exchange pipe be referred to as energy stake (or claim energy
Source stake, energy heat exchange stake).Energy stake technology is one of most typically technical scheme the most effectively utilizing shallow layer geothermal energy;
In conjunction with the difference of concrete piling strtucture form, create the energy stake type (document 1 that different shallow layer geothermal energy heat transfers utilizes
~16).
