Description
Technical field
The present invention relates to ground source heat pump imbedded pipe method of construction, especially a kind of underground pipe earth source heat pump horizontal pipe construction method based on quarrel stratum, the pool.
Background technique
As everyone knows, energy and environment are two hang-ups of 21 century facing mankind, and are in the China of Rapid development stage, and its problem is especially outstanding.In order to address this problem, the earth-source hot-pump system of energy-conserving and environment-protective is progressively promoted at home, wherein buried pipe ground-source heat pump system is one of most widely used mode of geothermal heat pump air-conditioning system, be characterized in by buried in rock-soil layer the circulatory mediator in PE pipe and rock-soil layer complete heat exchange,, there is not the geological problem causing because of groundwater abstraction in the not direct exploiting groundwater of which.But because China is vast in territory, geological condition complexity, is greatly limited the construction quality of underground pipe and Economy.Especially for the quarrel stratum, the pool of the coastal south, the construction of underground pipe earth source heat pump horizontal pipe is greatly limited.For region following the line of the sea, in the time that pool quarrel layer thickness exceedes for 2.6m, often because of stratum settlement occurred level pipe fracture accident.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of underground pipe earth source heat pump horizontal pipe construction method based on quarrel stratum, the pool is provided, safety that can level of protection pipe, can ensure again certain bearing capacity, prevents land subsidence.
For achieving the above object, technological scheme of the present invention is: a kind of underground pipe earth source heat pump horizontal pipe construction method based on quarrel stratum, the pool, according to outdoor ground designing requirement, outdoor ground design relative elevation is-0.4m, terrain face relative elevation is-1.2m, the about 2.6m of pool thickness of slag layer, at the bottom of the slag of the pool, absolute altitude is-3.8m, the design buried depth of horizontal pipe is subsurface 2m, horizontal pipe center absolute altitude is-2.4m, first carry out the pool slag blanket excavation of the large size 1.2m degree of depth, then carry out the pre-lower 2m sleeve pipe in underground pipe boring location, sleeve pipe adopts bellows, after having holed, bellows is stayed in hole and can be played and ensure to return effect on mud, under sleeve pipe, pipe completes, carry out again the construction of rig vertical tube, after vertical tube has been constructed, first carry out the 0.6m degree of depth, put slope at 1: 1, the horizontal ditch excavation that bottom width is 1 meter, then the thick plastic shape cohesive soil of backfill 0.4m, the yellow sand that backfill 0.4m is thick, carry out again horizontal pipe construction and be placed in the middle of yellow sand, thereafter above yellow sand, carrying out the plastic shape cohesive soil that 0.4m is thick covers, and carry out the parcel of geotextiles.
Horizontal pipe comprises that a horizontal pipe water pipe, a horizontal pipe return pipe and a horizontal pipe backwater are with journey pipe, and 2m cannula tip and horizontal pipe center are contour, and 2m sleeve pipe is between horizontal pipe water pipe and horizontal pipe return pipe.
Vertical tube is high density polyethylene pipe, and two high density polyethylene pipe head ends connect respectively horizontal pipe water pipe and horizontal pipe return pipe, and end is connected and is connected by single U-shaped pipe, the outside backfill that covers of high density polyethylene pipe.
The invention has the beneficial effects as follows: safety that can level of protection pipe, can ensure again certain bearing capacity, prevent land subsidence.
