Description
Technical field
The present invention relates to a kind of ground source heat pump line method of installation, especially a kind of ground source heat pump line method of installation based on planting a process.
Background technology
Ground source heat pump technology utilizes deep layer constant temperature underground heat as a kind of means of the energy, needs the embedding ground source heat pump line to ground depths.The conventional construction method of embedding ground source heat pump line can be summarized as following three classes up to now:
The first, again insert ground source heat pump line to ground deep layer soil layer by projected depth boring with rig.Ground source heat pump line is flexible pipe body, conduct oneself with dignity relatively light, intubate work progress is subject to the buoyancy of mud or underground water, therefore the artificial intubate of general employing, but artificial intubate is difficult to the degree of depth being accurately embedded into design, speed of application is comparatively slow, also needs to pay the expenses such as rig advance and retreat field expense and working day cost, so not only can produce the defects such as the high and efficiency of cost is low, while construction quality can not be guaranteed.
The second, ground source heat pump line is embedded in concrete drilling bored concrete pile and pouring concrete one.By the colligation of ground source heat pump line in the reinforcing cage of concrete drilling bored concrete pile, imbed together with reinforcing cage in stake holes; But reinforcing cage adopts segmented to install, and the part of ground source heat pump line in underground can not have joint, therefore can not segmentation install, and must bury underground, so there is larger construction interference by the entire length of design; Require that concrete drilling bored concrete pile must be provided with the concrete super perfusion section of certain length on the absolute altitude on design stake top according to job specfication; therefore the operation that there is cutter pile crown is also needed; the ground source heat pump line being difficult to available protecting pre-buried is not in the process destroyed; once there is fracture; ground source heat pump line is just scrapped because repairing; need to take boring supplement ground source heat pump line to make up, so not only schedule delays but also increase cost and drop into.This construction method complicated operation and to be constructed into power lower, the earth source heat pump tube heat exchange performance be simultaneously cast in concrete also can affect adversely.
3rd, ground source heat pump line is embedded in the stake holes of prefabricated concrete pipe pile.After pile sinking completes, then ground source heat pump line is inserted in stake holes.Adopting the ground source heat pump line of this method of installation and the earth, soil layer is insufficient contacts, and heat exchange performance is more weak; Because stake top will embed certain length in concrete foundation, ground source heat pump line can not be crossed in the soil layer that stake top bends towards at the bottom of concrete foundation again, therefore will cut a hole poling pile lining makes ground source heat pump line bend towards in the soil layer at the end, basis, so not only to construct trouble, also can destroy pile tube roof construction, affect the bearing capacity of pile tube.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of easy construction based on the ground source heat pump line method of installation of planting a process, buried underground rear ground source heat pump line with the earth soil layer heat exchange performance good.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of ground source heat pump line method of installation based on planting a process, comprises the following steps:
1): plant stake holes with pile driver boring formation, the described internal diameter of planting stake holes is greater than the external diameter of pile tube;
2): fixedly mount at least one hook at the external surface of described pile tube near bottom place, earth source heat pump pipe is prepared by predetermined length and quantity, described ground source heat pump line is fixed on described hook, described ground source heat pump line is fixed on the tube wall of described pile tube;
3): described pile tube is vertically suspended to and described plants directly over stake holes;
4): described pile tube is put into described stake holes of planting and utilize the deadweight of pile tube to sink, described ground source heat pump line is embedded in underground by the traction of described hook.
The external surface of described pile tube is near bottom place around being provided with steel hoop, and described hook is fixedly installed on described steel hoop.Adopt this structure installment ground source heat pump line very convenient.
Described steel hoop is doughnut-shaped steel plate, and described welding hook is on described doughnut-shaped steel plate, and the two ends bolt tightening of described doughnut-shaped steel plate is fixed.Not only save the material of steel hoop, reduce costs; Earth source heat pump pipe can be close to the external surface of pile tube simultaneously, reduces the resistance be subject in ground source heat pump line embedded process.
Described ground source heat pump line curves " U " font and is articulated on described hook, the top of described hook is provided with at least two soft grommets around described pile tube, and the external surface of described ground source heat pump line and described pile tube firmly fetters by described soft grommet.Ground source heat pump line is fixed on the external surface of pile tube, and fully contact with the earth soil layer, heat exchange performance is better.
Described pile tube forms by being fixedly linked according at least two joint unit pile cutoff head and the tail of designing requirement, and the installation step of described pile tube is as follows:
1) steadily place pile extension fixed mount planting ground, stake holes place, described pile extension fixed mount is provided with the through hole that internal diameter is greater than the stake footpath of described unit pile cutoff, and described through hole aligns with described stake holes of planting;
2), when the top of first unit pile cutoff is close to ground, admittedly overlaps with hawser and first unit pile cutoff is fixed on described pile extension fixed mount through described through hole, second unit pile cutoff is vertically suspended in directly over first unit pile cutoff;
3) by first unit pile cutoff and second unit pile cutoff by weld or machinery is fixedly connected with fixing, connecting place formation internode joint.
Compared with prior art, the invention has the advantages that to plant stake holes larger than the stake footpath of pile tube, pile tube and plant between stake holes and form mud-filled space, therefore planting pile tube in a process relies on deadweight to sink, by the tractive force of hook ground source heat pump line imbedded the degree of depth at place bottom pile tube, ground source heat pump line is fully contacted with the earth soil layer, and heat exchange performance is good, avoids the trouble of artificial intubate simultaneously; The process of burying underground of ground source heat pump line with plant a course synchronization and carry out, without the need to extra punch device, reduce construction cost, and ground source heat pump line embedding time without the need to merogenesis, reduce ground source heat pump line and imbed the risk that fracture occurs under ground portion, to pile tube to plant the interference of process little, can embedding many ground source heat pump lines simultaneously under the condition that engineering design allows.
