Abstract
The invention relates to a reinforced concrete well pile utilizing geothermal energy. In a well which is 5 to 300m deep and is manually dug or mechanically dug, a closed well is cast by reinforced concrete, and two pipelines with inflow and outflow fluids are inserted into the well. The diameter of the well, the thickness of the well wall and the reinforced bar structure are enlarged along with the increase of the pressure of a building. Heat exchange is carried out between cold and hot media fluids circulating in the well and underground soil rocks by the well wall. The system application refers to that a plurality of concrete well piles are connected in parallel into a net after being connected in series. Adopting the reinforced concrete well pile utilizing geothermal energy saves power and electricity, and is beneficial to a geothermal energy central air condition to be popularized in common housing districts. The closed well and a building pile are combined into a whole, thereby saving the application cost of the geothermal energy and the land utilization area.
Description
Technical field
The present invention relates to a kind of reinforced concrete well pile that utilizes the ground energy.
Technical background
Can make the air-conditioning of heat exchange at present, the mode that adopts pipe laying mostly or dig a well and draw water and recharge with utilizing.The pipe laying mode, because low, the complex process of heat exchange efficiency does not reach Air-conditioner design standard and actual instructions for use, very difficult large tracts of land is promoted the use of; Draw water and recharge, owing to be rich in the hard water of mineral matters such as calcium, magnesium, easily fouling in heat exchanger of air condition descends air-conditioner efficiency.And this mode can only be used for the earth source heat pump central air conditioner system of conventional junction configuration, and traditional structure earth source heat pump central air conditioner system operation control is complicated, essential outfit personal management, maintenance, repair.Be used for residential quarters, share the expenses and operating cost are all higher, and inconvenience is promoted.
Summary of the invention
Purpose of the present invention is will provide a kind of can utilize ground energy resource, and can be used as the sealing reinforced concrete well pile of building pile foundation or accessory building pile foundation.
Technical scheme of the present invention is: in the pile foundation position of building, with artificial or machinery excavates 5---in the dark well of 300M, with sealing well of armored concrete cast, have in two pipeline fill-in wells of fluid, wherein one is the bottom of well-insulated pipeline fill-in well.The diameter of well, thickness of shaft wall and bar construction strengthen according to the increasing of aboveground building pressure and height.
Be circulated in the cold and hot media fluid in the well, carry out heat exchange by the borehole wall and underground rock.System applies, generally by after the series connection of a plurality of concrete well piles again and be unified into net.Adopt the present invention, energy saving is convenient to ground energy central air-conditioning in general residential quarters penetration and promotion.Sealing well and building pile foundation are integrated, and save applicable cost in ground and land use area.This well irrigation is annotated cold and hot medium of exchange water and is forced into more than the 0.02MPa non-leakage.
Description of drawings
Accompanying drawing is an organigram of the present invention.
Among the figure 1, the sealing well, 2, the borehole wall, 3, go up pipeline, 4, pipeline down, 5, water-guiding hole.
The specific embodiment
Introduce the present invention below in conjunction with accompanying drawing.
With reference to accompanying drawing, under the pile foundation position of building, excavating one 10---30M is dark, and the well of diameter 1.2---2M is poured into a mould the sealing well 1 of a reinforced concrete structure then.In the sealing well, top has one to go up pipeline 3, and following pipeline 4 is from top to down near the shaft bottom, and there is water-guiding hole 5 lower end.Be convenient to convection current for making entery and delivery port keep the bigger temperature difference, following pipeline 4 adopts effect of heat insulation plastic pipe preferably.Upper and lower pipeline in the sealing well can be used separately as inlet tube and outlet tube, promptly is circulated in the cold and hot media fluid in the well, can advance by above pipeline, and following pipeline goes out; Also can advance by following pipeline, last pipeline goes out.
Claims (3)
- One kind utilize ground can reinforced concrete well pile, it is characterized in that:, excavate one 5 with artificial or machinery in the pile foundation position of building---the well that 300M is dark with sealing well of armored concrete cast, has in two pipeline fill-in wells of fluid.
- 2. by the described reinforced concrete well pile of claim 1, it is characterized in that: go up the top that pipeline (3) places well, following pipeline (4) is from top to down near the shaft bottom.
- 3. by the described concrete well pile of claim 1, it is characterized in that: described sealing well (1) is combined as a whole with building pile foundation; Described pipeline (4) adopts the plastic pipe of good heat-insulation effect.
