Description
Affiliated technical field:
The present invention relates to architectural engineering scraps precipitation well packing technology and combines with closed ground source heat pump technology, be that a kind of utilize in the scrapped project precipitation well inserted the tubular exchanger device and carried out cryogenically a kind of direct burial ground heat exchanger of thermal power transfer, this device not only can be scrapped architectural engineering precipitation well safety packing but also possess the cryogenically multi-functional direct burial ground heat exchanger of heat energy cycle heat exchange ability.
Background technology:
At present, known engineering dewatering well mainly is meant the pipe well that is the engineering dewatering service, and their pot life is limited, generally is accompanied by the end of major project or excavation project construction and finishes.35), influence problem such as other concealed work normal construction the precipitation well of scrapping is packing in time, and (close superly, when well will have eaten the people, labour protection magazine, 2000 (6): otherwise will gang up polluted underground water, cause potential safety hazard.Local government also puts into effect relevant policies and scraps the essential packing (city, Harbin City using water wisely management rules, Taiyuan City's water resources management way etc.) in time of well.The design of present engineering dewatering well mainly be according to engineering dewatering require, the hydrogeologic condition in place and related specifications (building and municipal dewatering project technical specification JGJ/T111-98), after main body or subdivisional work finish, adopt materials such as gravel, clay, cement according to actual conditions packing well, concrete grammar mainly contains full well packing method, uses method (Guo Fusheng etc. such as bridge formation packing method, open-work packing method, static blasting packing method, cement embedding, clay packing, the discussion of discarded well packing technical method, mineral exploration engineering, 1999 (increasing): 417).
The structure of each bore engineering dewatering well generally is to be made of gravel material, casing, worry water pipe, sand sediment pipe, water pump etc., works to reduce to descend partly water level, and engineering finishes the back packing.But the function of still not having the geothermic gradient utilized, this has ignored the heat exchange effect of burying of precipitation well.And in the middle-latitude zone, ground temperature is compared with ground environment, the following annual ground temperature of 5-10m can be stable at year-round average temperature substantially, can be respectively provide in two seasons of winter in summer relatively low condensation temperature and higher evaporating temperature (Gaoqing, in ring, the development and utilization of efficient height, heating and cooling equipment one earth source heat pump that environmental protection efficacy is good, the Jilin Industry University natural science journal, in April calendar year 2001, Vol.31 (2): 96-102), this is the operation principle of earth source heat pump.The pipe laying method of ground source heat pump technology mainly is that U type polyethylene pipe is directly buried in prebored hole underground at present, its expense is very high, generally can account for the over half of gross investment, initial cost (Jiang Baocheng, the Wang Yong boomerang of electric heat pump under the same terms etc., LiBing Xi, the Technological Economy evaluation of earth source heat pump, Harbin Institute of Technology's journal, the 35th the 2nd phase of volume of February in 2003,195-202), this causes difficulty for the development of this technology.About pipe laying in the stake, the domestic people of having proposed the notion of U type stake buried tube heat exchanger, but this method in essence still the boring of traditional earth source heat pump directly bury the improvement of U type heat exchanger tube underground, only the filler in the boring is changed into cement mortar.(Zhao Jun, Li Xinguo etc., earth source heat pump be in actual application in engineering and research, building construction technology (tianjin building science and technology), and 2003, No.5:14-16).Though external also someone put forward the notion that heat exchanger is buried in stake, but all be based on high-strength polyethylene U type coil pipe concrete perfusion solid section stake (Laloui Lyesse, Moreni Matteo, Vulliet Laurent, Behavior of a bi-functional pile, foundation and heat exchanger, Canadian Geotechnical Journal, v 40, and n 2, April, 2003, p 388-402.), these based on the shortcoming of burying tubular exchanger in boring or the various cast-in-place concrete pile underground are: boring expense height, coil heat exchanger construction in the cast-in-place concrete pile is complicated, needs operations such as coil pipe assembling reinforcement cage.And the coil pipe position local material softened zone and stress can occur and concentrates in all kinds of solid section stakes, influence pile quality, to traditional load-carrying properties generation detrimental effect of pile foundation.The tubular exchanger of various in addition polyethylene materials is extruded the risk of destruction in addition.In addition, the open utility model of domestic existing is called " a kind of underground energy resource collecting pile ", its application number be (200410082851.1,200520090102.3) publication number be (CN1786615, CN2780832).It has only considered that tubular exchanger is the tubular exchanger of one group of U type coil pipe or open similar thimble tube, and their heat exchanger efficiency is not high, and does not acquire backfilling material at the pile tube hollow stake heart, directly the heat exchange efficiency of influence and soil layer.In addition, when pile tube during, do not consider the pipeline heat insulation problem of near surface in winter as fender post or stake top near surface.
Summary of the invention
What is called is heat energy (Low Temperature Earth-heat-energy) cryogenically, is meant the low-temperature heat energy that absorbs solar energy, geothermal energy in surface soil, underground water or river, the lake and contain.Scrap the precipitation well and handle and only to consider its packing and to ignore the function that it utilizes the geothermal using gradient in order to overcome existing engineering, and it is complicated and to the reality of the adverse effect of cast-in-place concrete pile base to change the construction of expensive, all kinds of tubular exchanger of closed ground source heat pump technology initial bore hole, the present invention can provide a kind of direct buried underground heat exchanger of engineering abandored water lowering well, this ground heat exchanger can not only the packing engineering be scrapped the precipitation well, and can carry out the cryogenically closed circulation conversion of heat energy of shallow-layer easily.
The technical solution adopted for the present invention to solve the technical problems is: the design of the engineering dewatering well that the present invention adopts, construction technology, examination are just the same with at present normal engineering dewatering well, all by national existing relevant specification (People's Republic of China's industry standard " building and municipal dewatering project technical specification JGJ/T111-98 ") execution.
After the engineering dewatering well construction finishes, by the normal precipitation operation of designing requirement, treat the end of major project or excavation project construction after, its pot life expires, and needs the packing operation.Patent of the present invention was meant before the packing operation, in the precipitation well of need packing, at first pass through the tubular exchanger of manpower or mechanical underlying high-strength polyethylene or PVC or PPR material, caliber is generally 19mm-38mm, the pipe vertical height is equal to well depth approximately, its tubular exchanger bottom is apart from shaft bottom 1m-2m, its tubular exchanger outlet makes progress and the certain thickness insulation material of colligation, the length of colligation is about 0.5m-2.0m, the outer span casing inwall of tubular exchanger is between 10mm-100mm, shape can be a U type heat exchanger tube, the screw type coil pipe, other type heat exchanger tube in thimble tube heat exchanger tube or " boring direct burial " method is scrapped one or more groups all kinds of tubular exchangers of arrangement in the precipitation well according to the actual heating load needs in engineering.Secondly, according to reality shut-in well designing requirement layering or all kinds of shut-in well backfilling materials of not stratified landfill in the abandoned well well, as clay, cement, gravel, 0m-2m inserts high-strength insulation backfilling material (as foamed plastics or perlite etc.) on distance well top.Operation mechanism according to earth source heat pump, these tubular exchangers are fixed on to be scrapped in the precipitation well, filling heat-exchange fluid in the tubular exchanger, this fluid adopts water, salt solution or various antifreezing agent solution usually, form cryogenically heat energy circulating system of enclosed type, each model earth source heat pump unit of face of land exchange pipeline, water pump and the satisfied actual different capacity that requires is installed.Thermostat layer by the exchange media in the tubular exchanger and backfilling material, former casing and shallow soil water system carries out the cycling hot exchange, and reach the purpose that energy transforms by the earth source heat pump unit, play the effect of central air-conditioning, if auxiliary then can provide central hot-water heating system institute calorific requirement with devices such as central heaters.
The invention has the beneficial effects as follows, can be when precipitation well safety packing be scrapped in architectural engineering, the tubular exchanger that is lowered in well promptly can not influence the packing effect, can carry out the closed circulation conversion of superficial part geothermal energy again easily, these engineerings are scrapped tubular exchangers such as U type pipe in the precipitation well, screw type coil pipe, can play the same effect of traditional closed earth source heat pump boring pipe laying, but save the correlative charges of prebored hole.
The engineering that adopts in this ground heat exchanger all kinds of tubular exchanger technology of underlying in the precipitation well of scrapping can be eliminated the various defectives (in the solid section bored concrete pile because the pile body local material softened zone that polyethylene exchange pipe causes) of pile foundation buried tube heat exchanger, can reach all indexs of the embedding heat exchanger of vertical drilling fully.In addition, this technology can also arbitrarily be provided with the group number of tubular exchanger, is example with U type heat exchanger tube, can require to be provided with 1 group, 2 groups or organize U type heat exchanger tube according to thermic load more.Tubular exchanger does not influence other engineer operation in the engineering of packing is scrapped the precipitation well.In addition, this technology is to construct in the sleeve pipe of scrapped project precipitation well, and this construction technology problems such as undergauge, the quicksand that may occur, the hole of collapsing of can avoiding holing having overcome the constructional difficulties that tubular exchanger is buried in boring underground.
Secondly owing to around the tubular exchanger of scrapped project precipitation well, need all kinds of backfilling materials of filling, can save the sealing material expense and the labour cost of scrapping the precipitation well, also finish the packing of scrapped project precipitation well simultaneously.Last because backfilling material can Artificial Control, on the basis of satisfying the packing designing requirement, can distribute the backfilling material of the optimum coefficient of conductivity rationally according to different areas, different geological conditions, to increase heat exchanger effectiveness.
This technology at first is a kind of of closure earth source heat pump, has the innate advantage of closed ground source heat pump technology.It can eliminate the underground water pollution problem in the source heat pump technology openly, also can avoid the operating groundwater resources usage charges of open system.Secondly at the closed ground source heat pump technology prebored hole of tradition, directly bury the not high construction shortcoming of complex procedures, precision such as U type heat exchanger tube underground, and the expensive excessive problem of ground source heat pump technology initial outlay that causes of whole embedding heat exchanger, this underground heat exchanger technology can be avoided prebored hole and bury the heat exchanger tube cost underground, the construction problem that only this item cost-saved nearly half and the direct-burried heat exchanger tube of avoiding holing bring.The various heat exchanger tube of varying number can be set in the precipitation well in addition flexibly: U type heat exchanger tube, screw type coil pipe or their combination, further reduce construction cost.As seen these technical measures will lower the comprehensive cost of whole earth source heat pump, earth source heat pump itself has the environmental protection and energy saving function, and China is manually cheap, scrapped project precipitation well huge amount, if cooperate promoting the use of of present technique, to bring hundreds of millions of economic benefits and environmental benefit every year, can save a large amount of non-renewable strategic resources such as oil coal for country again.
