Summary of the invention
The present invention seeks to: propose the pre-buried earth source heat pump pile tube of a kind of castinplace pile cap node; by being set in stake top bit, stake emits node; effectively protect pre-buried ground source heat pump line, guaranteed the survival rate of ground source heat pump line, guaranteed the stress structure requirement of pile body and base plate simultaneously.
Technical scheme of the present invention is: the pre-buried earth source heat pump pile tube of a kind of castinplace pile cap node, comprise engineering the drilling stake and be embedded in the ground source heat pump line in engineering the drilling stake, the top of described engineering the drilling stake is provided with described ground source heat pump line top parcel concrete pile follower within it.
Described concrete pile follower comprises the pile cover body of concrete material, is provided with structure muscle and the some ring-shaped stirrups that distribute up and down of some horizontal distribution in described pile cover body.
Described concrete pile follower also comprises and is coated on this external rubber thermal insulation casing of described pile cover.
The outline of described concrete pile follower is cylindrical, and it is highly 100mm, and diameter is 1300mm.
Described ring-shaped stirrup has three, and the vertical spacing between adjacent two ring-shaped stirrups is 30mm.
Described ground source heat pump line is PE pipe.
Described engineering the drilling stake comprises the some vertical reinforcements that distribute ringwise of arranging in it and is wrapped in the spiral stirrup that these vertical reinforcements have outward, described ground source heat pump line is close to described spiral stirrup inner side and vertical reinforcement sidepiece is arranged, and by Plastic Bandage, bands together between ground source heat pump line and vertical reinforcement.
Advantage of the present invention is:
1, effectively guarantee to arrange in a survival rate of position, top ground source heat pump line and stake the feasibility of ground source heat pump line;
2, met the design structure requirement on base plate and engineering the drilling stake stake top.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be described further:
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Wherein: 1 engineering the drilling stake, 1-1 vertical reinforcement, 1-2 spiral stirrup, 1-3 Plastic Bandage,
2 ground source heat pump lines,
3 concrete pile followers, 3-1 pile cover body, 3-2 ring-shaped stirrup, 3-3 rubber thermal insulation casing,
4 base plates.
The specific embodiment
As shown in Figure 1, the pre-buried earth source heat pump pile tube of the castinplace pile of the present embodiment cap node, comprises engineering the drilling stake 1 and is embedded in the ground source heat pump line 2 in engineering the drilling stake, and wherein ground source heat pump line 2 is PE pipe.The top of described engineering the drilling stake 1 is provided with concrete pile follower 3, and this concrete pile follower 3 wraps up the top of described ground source heat pump line 2 within it, thereby the pipe that picks out of place, 1 top of protection engineering the drilling stake ground source heat pump line 2 exempts from destruction in the base arrangement construction stage.
As shown in Figure 2, described concrete pile follower 3 comprises the pile cover body 3-1 of concrete material, is provided with structure muscle (not shown) and the some ring-shaped stirrup 3-2 that distribute up and down of some horizontal distribution in described pile cover body 1.
In the present embodiment, the outline of concrete pile follower 3 is cylindrical, and it is highly 100mm, and diameter is 1300mm.Described ring-shaped stirrup 3-2 has three, and the vertical spacing between adjacent two ring-shaped stirrup 3-2 is 30mm.During Specific construction, increase by three ring-shaped stirrup 3-2 divide other to construct muscle with many levels in engineering pile drilled pile 1 base plate dowel position, disturbing concrete then, just forms that 100mm is high, the concrete pile follower of diameter 1300mm 3.
In order to make this concrete pile follower 3 have good heat-insulating property, the concrete pile follower 3 in this example also comprises the rubber thermal insulation casing 3-3 being coated on outside described pile cover body 3-1.
Described engineering the drilling stake 1 comprises the some vertical reinforcement 1-1 that distribute ringwise that arrange in it and is wrapped in the spiral stirrup 1-2 that these vertical reinforcements have outward, described ground source heat pump line 2 is close to the inner side of described spiral stirrup 1-2 and is close to the sidepiece of vertical reinforcement 1-1 simultaneously, and with Plastic Bandage 1-3, bands together between ground source heat pump line 2 and vertical reinforcement 1-1.
The pre-buried earth source heat pump pile tube of castinplace pile cap node in the present embodiment completes before base plate 4 constructions; the Structural Tectonics form of pile cover has been guaranteed 1 top of engineering the drilling stake and base plate 4 design structure requirements, earth source heat pump pipe 2 has been played to protective effect in the construction stage simultaneously.
