Description
Technical field
The utility model relates to geothermal source underground pipes, facilitate fixed combined type ground source heat buried more particularly, to a kind of
Pipe.
Background technique
Currently, geothermal heat pump air-conditioner needs the pre-buried underground pipe below earth's surface during the installation process, during Specific construction
It needs first to excavate geothermal well, then underground pipe is installed in geothermal well.Due to geothermal well in work progress depth of falling well compared with
Greatly, the slime water in geothermal well can generate biggish buoyancy to tubing, and underground pipe is generally the U-bend made of PE material
Pipe, density thus cannot rely on gravity down tube well below the density of slime water.
In the prior art, generally one stay bolt can be set at position among U-tube, construction personnel can be passed through using metal tube
Stay bolt send underground pipe to predetermined depth.
Above-mentioned prior art has the following deficiencies: that in actual use metallic rod is easy to cause to damage to pipeline
It is bad, and difficulty of construction complicated for operation is larger, before being backfilled after the completion of down tube, if underground pipe is not completely fixed, in mud
It is easy to happen floating under the buoyancy of water and exchanges thermal effect and brings adverse effect.Therefore, it is generally needed as early as possible after down tube
Backfill, so as to cause after down tube to underground pipe suppress leak detection work it is generally insufficient so that underground pipe is easy to happen damage.It is buried
Pipe will lead to entire geothermal well if being damaged and scrap to bring about great losses.
Utility model content
The purpose of the utility model is to provide a kind of geographical thermally pipe layings of combined type, have the advantages that facilitate fixed.
The above-mentioned technical purpose of the utility model has the technical scheme that
