Abstract

Disclosed is a screw pile. Screw blades are arranged on the outer wall of a pile column, two sealing sheets are arranged at the upper end and the lower end of the interior of the pile column respectively, a water outlet and a water inlet are formed in the sealing sheet at the upper end, the lower end of the water outlet is connected with a flow guide pipe, and the upper end of the water inlet and the upper end of the water outlet are connected with external water pipes. Due to the fact that the structure is adopted, the interior of the screw pile is sealed, a water storage space is formed, laying of a large number of water pipes is not required after pile driving operation is accomplished, a water inlet pipe and a water outlet pipe are directly connected with the screw pile, and the purpose that the construction cycle is shortened is achieved; due to the fact that the size and the number of the screw blades are increased, conduction of terrestrial heat is quickened, heat exchange between the terrestrial heat and water in the screw pile can be conducted more fully and more quickly, and the utilization efficiency of the terrestrial heat is improved; the cost for laying of the water pipes is reduced, the purpose that the construction cycle is shortened is achieved, and construction of a whole water and ground source heat pump air conditioner can be quicker and more efficient.

Description

A kind of screw pile
Technical field
The present invention relates to a kind of screw pile, particularly a kind of screw pile.
Background technology
Existing heat pump air conditioner comprises water geothermal heat pump air-conditioner and air source heat pump air-conditioner, the Energy Efficiency Ratio of water geothermal heat pump air-conditioner is roughly about the twice of air source heat pump air-conditioner, but because water geothermal heat pump air-conditioner installation period is long, need provided underground pipeline, need to excavate zanjon.So the popularity rate of present water geothermal heat pump air-conditioner is far away from the popularity rate of air source heat pump air-conditioner.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of screw pile, by directly setting up water space in screw pile, realizing the installation of water pipe, substantially reduce construction period while carrying out driving piles.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of screw pile, pile outer wall is provided with helical blade, the inner two ends up and down of pile are respectively equipped with the first diaphragm seal and the second diaphragm seal, first diaphragm seal is provided with delivery port and water inlet, delivery port lower end is connected with a mozzle, and water inlet is connected with outer water tube with delivery port upper end.
In preferred scheme, described mozzle lower end length arrives pile bottom or pile centre position.
A kind of screw pile, pile outer wall is provided with helical blade, and the inner two ends up and down of pile are respectively equipped with the first diaphragm seal and the second diaphragm seal, first diaphragm seal is provided with water inlet, second diaphragm seal is provided with delivery port, and water inlet upper end is connected with outer water tube, and delivery port lower end is connected with mozzle.
In preferred scheme, described mozzle is located at that screw pile is outer and mozzle is close to screw pile outer wall.
In preferred scheme, due to mozzle Long Term Contact current and be laid on underground, the anti-etch-proof material that gets rusty can be adopted.
In preferred scheme, in work progress, can at the outer sheathed case pile of screw pile, because the rotation difficulty of long stake is comparatively large, a smooth case pile is set, piling efficiency can be promoted.
In preferred scheme, described helical blade also can change ring-shaped blade into.
In preferred scheme, mozzle also can be connected on water inlet lower end.
In preferred scheme, pile upper end can arrange interface (as hickey or buckle), may be used for the length increasing or shorten pile, to meet the construction works of different depth demand.
In preferred scheme, described screw pile is applicable to water earth source heat pump, but is not limited to water earth source heat pump, can also be applied in other construction workss such as to lay the foundations.
A kind of screw pile provided by the invention, by adopting above structure, screw pile inside being sealed, forms a water space, after having driven piles, burying water pipe without the need to spreading in a large number, directly water inlet pipe is connected with screw pile with outlet pipe, reach the object shortening construction period, and by increasing the size and number of helical blade, accelerate thermal conductive, enable underground heat more fully carry out interchange of heat with the water in screw pile fast, add geothermal utilization efficiency.In use, pass into current by water inlet by screw pile, current and underground water, soil flow out after completing interchange of heat from outlet pipe, realize the utilization to underground heat.By above structure, having saved while paving buries the cost of water pipe, also reaching the object shortening construction period, whole water geothermal heat pump air-conditioner is constructed more rapidly and efficiently.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation of the present invention.
Fig. 2 is another kind of structural representation of the present invention.
In figure: pile 1, helical blade 2, the first diaphragm seal 3, second diaphragm seal 3 ', delivery port 4, water inlet 5, mozzle 6.
Detailed description of the invention
As in figure, a kind of screw pile, pile 1 outer wall is provided with helical blade 2, the inner two ends up and down of pile 1 are respectively equipped with a diaphragm seal 3, the diaphragm seal 3 of upper end is provided with delivery port 4 and water inlet 5, delivery port 4 lower end is connected with a mozzle 6, and water inlet 5 is connected with outer water tube with delivery port 4 upper end.By said structure, directly utilize screw pile to carry out underground heat Collection utilization, burying water pipe without the need to spreading in a large number, not only having saved cost and having shortened construction period.
In preferred scheme, described mozzle 6 lower end length arrives pile 1 bottom or pile 1 centre position.
As in Fig. 2, a kind of screw pile, pile 1 outer wall is provided with helical blade 2, the inner two ends up and down of pile 1 are respectively equipped with the first diaphragm seal 3 and the second diaphragm seal 3 ', first diaphragm seal 3 is provided with water inlet 5, second diaphragm seal 3 ' is provided with delivery port 4, and water inlet 5 upper end is connected with outer water tube, and delivery port 4 lower end is connected with mozzle 6.
In preferred scheme, described mozzle 6 is located at that screw pile is outer and mozzle 6 is close to screw pile outer wall.
In preferred scheme, described mozzle 6 can adopt the anti-anticorrosive that gets rusty.Because the mozzle in screw pile needs Long Term Contact current, can consider to adopt the anti-anticorrosives that get rusty such as stainless steel, make its application life more permanent.
In preferred scheme, pile upper end inwall can arrange interface (as hickey or buckle).Can carry out again setting up pile above screw pile pile with this, the length of whole pile is regulated, pile is beaten darker.
In preferred scheme, in work progress, because the rotation of long stake is more difficult, efficiency of construction can be caused low, by setting up a smooth case pile outside screw pile, case pile and screw pile are together driven piles, and promote the efficiency of piling with this.
Owing to being provided with smooth case pile, so helical blade also can adopt ring-shaped blade, then by increasing blade quantity and size, raising heat exchanging efficiency.
