Description

The pre-buried earth source heat pump pile tube of castinplace pile cap node
Technical field
The present invention relates to the civil engineering field, specifically is the pre-buried earth source heat pump pile tube of a kind of castinplace pile cap node.
Background technology
For responding the relevant policies of national green building, keep the comprehensive and sustainable utilization of the energy, wide model adopts ground source heat pump technology in new construction at present.
In deep-foundation pit engineering, engineering was embedded in earth source heat pump U type pipe in the diaphragm wall mostly in the past, and pre-buried in the engineering the drilling stake also do not have successful case, but because the stake top bit was prone to be destroyed in the base plate construction stage, need node is designed.
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; Through being set in the 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 the engineering the drilling stake and be embedded in the ground source heat pump line in the engineering the drilling stake that the top of said engineering the drilling stake is provided with said ground source heat pump line top parcel concrete pile follower within it.
Said concrete pile follower comprises the pile cover body of concrete material, is provided with structure muscle and some ring-shaped stirrups that distribute up and down of some horizontal distribution in the said pile cover body.
Said concrete pile follower also comprises and is coated on this external rubber thermal insulation casing of said pile cover.
The outline of said concrete pile follower is cylindrical, and it highly is 100mm, and diameter is 1300mm.
Said ring-shaped stirrup has three, and the vertical spacing between adjacent two ring-shaped stirrups is 30mm.
Said ground source heat pump line is the PE pipe.
Said engineering the drilling stake comprises the some vertical reinforcements of arranging in it that distribute ringwise and is wrapped in the spiral stirrup that these vertical reinforcements have outward; Said spiral stirrup inboard is close to by said ground source heat pump line and the vertical reinforcement sidepiece is arranged, and bands together through Plastic Bandage between ground source heat pump line and the vertical reinforcement.
Advantage of the present invention is:
1, effectively guarantees to be provided with in a survival rate of position, top ground source heat pump line and the stake feasibility of ground source heat pump line;
2, satisfied the design structure requirement on base plate and engineering the drilling stake stake top.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further introduction:
Fig. 1 is the structural representation of the embodiment of the 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 present embodiment cap node comprises engineering the drilling stake 1 and is embedded in the ground source heat pump line 2 in the engineering the drilling stake, and wherein ground source heat pump line 2 is the PE pipe.The top of said engineering the drilling stake 1 is provided with concrete pile follower 3, and this concrete pile follower 3 wraps up the top of said 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, said concrete pile follower 3 comprises the pile cover body 3-1 of concrete material, is provided with structure muscle (figure does not show) and some ring-shaped stirrup 3-2 that distribute up and down of some horizontal distribution in the said pile cover body 1.
In the present embodiment, the outline of concrete pile follower 3 is cylindrical, and it highly is 100mm, and diameter is 1300mm.Said ring-shaped stirrup 3-2 has three, and the vertical spacing between adjacent two ring-shaped stirrup 3-2 is 30mm.During concrete construction, increase by three ring-shaped stirrup 3-2 in engineering piles drilled pile 1 base plate dowel position and divide with many levels and else construct muscle, disturbing concrete then just forms the concrete pile follower 3 of 100mm height, diameter 1300mm.
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 that is coated on outside the said pile cover body 3-1.
Said 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; Said ground source heat pump line 2 is close to the inboard of said spiral stirrup 1-2 and is close to the sidepiece of vertical reinforcement 1-1 simultaneously, and bands together with Plastic Bandage 1-3 between ground source heat pump line 2 and the vertical reinforcement 1-1.
The pre-buried earth source heat pump pile tube of castinplace pile in present embodiment cap node is accomplished before base plate 4 constructions; The structure construction form of pile cover has been guaranteed 1 top of engineering the drilling stake and base plate 4 design structure requirements, simultaneously earth source heat pump pipe 2 has been played protective effect in the construction stage.
Certainly, the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let people can understand content of the present invention and implements according to this, can not limit protection scope of the present invention with this.The all spirit of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
