Description
Technical field
The invention belongs to energy stake technical fields, and in particular to the cast-in-place pile type energy stake of kind novel belt energy storage device.
Background technique
Energy stake is to combine pile foundation with earth source heat pump, can both carry fabric structure, while using shallow-layer
The a large amount of low-temperature heat sources stored in lower soil, rock, underground water or other media provide heating, air-conditioning and heat for space
Water, it overcomes the defect of the ground-source heat pump system of vertical drilling hole pipe laying, while can reduce the land occupation face of ground-source heat pump system
Product and investment are a kind of green building techniques of low cost highly widelyd popularize.
Currently, the building basis in China is using cast-in-situ bored pile as principal mode, energy stake refers generally in cast-in-situ bored pile
In pre-buried plastics heat exchange tube (usually PE pipe), then removed in stake well with steel reinforcement cage one, then casting concrete forms.Its
In, plastics heat exchange tube there are mainly five types of type, respectively it is single it is U-shaped, connect double-U-shaped (W type), be in parallel double-U-shaped, in parallel three U-shaped
With single-screw type.
In the research application of domestic and international existing energy stake heat exchanger tube few in number at present, plastic heat exchanger tube is mainly continued to use
U-shaped, W type or screw type cloth Manifold technology.In order to increase heat transfer area, the service efficiency of energy stake is improved, W type is often used
Or U-shaped, spiral shape piping mode in parallel, the heat exchange efficiency of energy stake is mentioned with the increase of pipe laying quantity or length on the whole
It is high.For energy stake, heat exchange is generated with surrounding soil while heat transferring medium (water) flows in pipe laying, when water in pipe laying
When reaching near the soil body of deeper, closer to the temperature of the underground deep layer soil body, heat transfer effect is better.
Current research relates generally to heat interference, different piping modes and increase heat transfer area between inlet and outlet pipeline section
Etc., purpose is intended to improve the heat exchange efficiency of energy stake, and the investigation of materials used for pipeline itself is also less, generally makes
It is managed with PE.And based on current existing measure technology, why still not fully up to expectations the heat exchange efficiency of energy stake is, pipe laying it is final
It is one of most significant reason that exit water temperature, which preferably cannot closely descend deep soil temperature,.
Summary of the invention
The technical problem to be solved by the present invention is to solve the above shortcomings of the prior art and to provide a kind of novel belt energy storage dresses
The cast-in-place pile type energy stake set.
To realize the above-mentioned technical purpose, the technical scheme adopted by the invention is as follows：
A kind of cast-in-place pile type energy stake of novel belt energy storage device, wherein：Including the energy stake to be formed, energy are perfused by pore-forming

Equipped with inlet and outlet, import is connect with heat conducting pipe, outlet connect with insulating tube, heat conducting pipe from energy stake top face vertically into,
Extend to the import of energy storage device；Insulating tube is drawn upwards from the exit normal of energy storage device, extends to energy stake top face, thermally conductive
Water circulating pump and heat pump heat exchanger are connected in series between the upper end of pipe, the upper end of insulating tube, heat transferring medium is in energy storage device
Cavity in advance energy storage, after being preheated to the underground soil temperature of the depth, water circulating pump operates again, make heat transferring medium along
The series loop flowing of water circulating pump, heat conducting pipe, energy storage device, insulating tube and heat pump heat exchanger composition.
To optimize above-mentioned technical proposal, the concrete measure taken further includes：
Above-mentioned heat conducting pipe and insulating tube upper end is mounted on temperature flow sensor, and temperature flow sensor can be according to heat conducting pipe
And the temperature of the heat transferring medium in insulating tube adjusts the power of water circulating pump.
Above-mentioned energy storage device is the hollow cylindrical cabinet that steel plate is welded, and is connected into one with steel reinforcement cage, is mixed
After solidifying soil pours, the hollow space of energy storage device will be filled, and be wrapped in outside the outer ring of energy storage device.
The vertical support frame for improving energy storage device structure intensity is fixed in above-mentioned energy storage device.
The madjack pipe for vertically extending to energy stake lower part is provided in above-mentioned energy stake.
Above-mentioned madjack pipe makes together when making the steel reinforcement cage of energy stake, and symmetrically binds in steel reinforcement cage, mud jacking
Pipe grout outlet is located at the stake end under energy storage device.After the completion of pile concrete pours, post grouting under pile is carried out.
Above-mentioned heat conducting pipe is copper pipe or steel pipe, and insulating tube is crosslinked polyethylene pipe or chlorinated polyvinyl chloride pipe.

Above-mentioned heat conducting pipe and insulating tube is straight type pipe.
Energy storage device containing heat transferring medium is placed in pile foundation bottom in advance by the present invention, is filled to heat transferring medium and ambient enviroment
After dividing heat exchange, underground energy " conveying " is arrived by ground by circulation loop, completes heat exchange.This advantageously accounts for heat exchange not
Abundant problem improves the heat exchange efficiency of energy stake.The present invention uses steel pipe in the descending branch (i.e. inducer) of heat exchange pipeline
The equal biggish metal tube of heat transfer coefficients, increases its heat transfer efficiency.Import pipeline section and outlet pipe section use the pipeline of different materials.Such as
Preceding described, there are mainly five types of type, single U-shaped, series connection double-U-shaped (W type), double-U-shaped, in parallel three U-shaped and spirals in parallel for pile foundation pipe laying
Type, but no matter which kind of form, pipeline material all do not change.The underground soil body according to Temperature Distribution difference, from top to bottom successively
Troposphere, thermostat layer, thermosphere can be divided into, and as pile foundation is deeper and deeper, Practical Project pile foundation is in thermostat layer or shallow
When layer thermosphere, the temperature difference is bigger, is more conducive to the progress of heat exchange.Enter in this segment pipe of underground at heat transferring medium (water), it should
Using the big pipeline of heat transfer coefficient (such as steel pipe), to carry out heat exchange sufficiently.But for ascent stage, heat transferring medium will be with
The soil body carries out opposite heat exchange, so the lesser pipeline of heat transfer coefficient should be used, such as with insulating tube (such as crosslinked polyethylene
Pipe PEX, chlorinated polyvinyl chloride pipe CPVC), to reduce unnecessary energy loss.
The present invention because of the above scheme, has the following advantages that：
1, energy storage is carried out in advance, and energy stake heat exchange efficiency is high, and heat exchange is sufficiently and energy loss is smaller；
2, the service efficiency of energy stake is improved, it is not necessary to worry the problem of pipe laying stroke deficiency in energy stake；
3, different engineering-environments are adapted to, wide usage is strong.
4, energy storage heat-exchanger rig is made into hollow ring, and is furnished with post jacking pipeline, makes energy storage heat-exchanger rig and pile body coagulation
Soil, which can pour, builds up an entirety, and eliminates pile bottom sediment or pour not firm hidden danger.
