Abstract
This invented method and device can realize integral original position lift-up protection to Wudang mountain ancient construction groups(walls, gates, palaces and corridors) and lift-up reconstruction of ancient construction groups or the existing buildings in cities and countryside.
Description
Technical field:
The present invention relates to a kind of method and apparatus of building jacking, particularly relate to the method and apparatus of a kind of building or heritage buildings/group's integral jacking.
Background technology:
China is an ancient civilized country, a considerable amount of ancient buildings and ancient buildings that various places are keeping; These ancient buildings and ancient buildings be as the history of solidifying, and write down and keeping a large amount of in history information, be the treasure that ancestors leave we descendant for, great protection and researching value are arranged.Since nearly 20 years; China's economy continues with surprising rapidity, stable development; the large-scale city process is constantly accelerated; big object of construction production is more and more; the contradiction of engineering construction and historical relic's protection is very outstanding; many important, valuable ancient buildings and ancient buildings have caused repairable never loss and sorry because technical having no idea and be forced to the misfortune of removing or removing inevitably is damaged these ancient buildings and ancient buildings to some extent.
Example: the south water to north work centerline that China goes into operation in recent years, by increasing the Danjiangkou Reservoir dam, improve normal pool level, increase storage capacity, thereby realize to North China's water transfer.After the completion of south water to north work centerline, the Danjiangkou Reservoir water level that is in flooding area will be risen to 168 meters by present 156 meters, this gap of 12 meters will make the important component part of the world cultural heritage Ancient Building Comoplex at Wudangshan that is positioned at the reservoir periphery---and meet true palace and forever flooded.Meet true palace and be built in the Ming Dynasty before more than 500 year, 33 in room, existing mausoleum is one of Wudang Mountain 33 place's ancient buildings, is positioned at chance Zhen Gong village, North Road, Wudang under the Wudang Mountain.All flooding in the historical relic below waterline, meeting true palace is to be worth maximum.Meeting true palace is " world cultural heritage ", and its existence is the symbol of long cultural and historical.Although important historical relic point in design, is thought with doing one's utmost to avoid departments in charge of cultural and historical relics by design department, meet true palace and flooded really and can't avoid.How protecting the true palace of chance has been extremely urgent problem.It should be noted that special " identity " of meeting true palace; agreement according to " protection world cultural and natural heritage pact "; all change the World Heritage Commission's approval that the way of meeting true palace present situation all must be reported UNESCO by world cultural heritage China Committee, just can implement.Whether the protected mode in the true palace of end-on science, rationally, will be directly connected to the attitude that China treats world cultural heritage.
Protection is met the present relevant department in true palace and has been proposed four kinds of rescuing schemes: 1. will meet true palace and remove the high reconstruction of original place frame; 2. will meet the disposable resettlement in true palace to other areas rebuilds; 3. outside meeting true palace, build check dam one, itself and reservoir area are isolated; 4. build dam in Danjiangkou Reservoir and Wudang Mountain intersection, directly cut off big flood in the future.Above-mentioned 4 kinds of rescuing scheme essence are 2 kinds of technical schemes, i.e. reconstruction technique scheme and build the dam technical scheme.
The reconstruction technique scheme: the high or disposable resettlement of original place frame promptly on the spot or the strange land build again, must remove meeting true palace earlier, to relic numbering, reorganization again.Can occur inevitably damage in the engineering, its original appearance also will be had a greatly reduced quality, and the most important thing is, meet the information in ancient times that true palace layout, structure, material preserve and will be subjected to considerable damage and eternal losing.The expert says in this way: artifact is all non-renewable, can not copy, and in a single day historical information loses, and what bring is irretrievable loss and shortcoming, " cries and all has little time " very till that time.As truly it being relocated, it will be a largest engineering of Ancient Chinese historical relic single building resettlement, and the estimation fund will be up to 4,000 ten thousand yuan.
Build the dam technical scheme: it not is a lot of meeting that the height above sea level in true palace and waterline differ, and it is less to build dam embankment engineering quantity, and protection is convenient to preserve the authenticity of meeting true palace and the integrality of Ancient Building Comoplex at Wudangshan total arrangement on the spot.Simultaneously, build check dam and also help near many places ancient building and the ruins true palace of protection chance, do convenient and swift really like this.Meeting true palace in front of the door but dam is horizontal, there is bigger drawback in head up to 12 meters---how draining? if cofferdam Zha Ba protects on the spot, wooden construction makes moist in low-lying location throughout the year, must quicken the deterioration of wooden structures.Also have inland river, streamlet around meeting true palace, flow is little, but problem is not little, uses water pump to draw water, and must adhere to for a long time, relates to personnel's establishment and cost issues.Count and, protection institute cost gold and rebuilds unlike resettlement and lack on the spot, and the maintenance cost with whole system of not considering throughout the year to draw water is only built dam fund about 60,000,000.
The method and apparatus of inventor's patent application in November, 2,005 2005100485111 described whole building jackings, limited because of top lifting height, cost is high, can't implement to solve the problem that true palace ran into of meeting.The awkward situation that above-mentioned case runs into illustrates that present engineering, historical relic lack a kind of method and technology of whole original position jacking relatively cheap, that extensively be suitable for to protection building, ancient building or ancient buildings.
Summary of the invention:
First purpose of the present invention provides the method for a kind of heritage buildings or ancient buildings integral jacking, makes similar south water to north work centerline meet the ancient building of true palace case or ancient buildings is avoided removing or tearing down and building, can whole original position jacking to design height.
Second purpose of the present invention provides the method for a kind of modern building or architectural complex integral jacking, can make building or architectural complex economically integral jacking can be widely used in the lifting reconstruction of modern existing building or architectural complex to design height.
The 3rd purpose of the present invention provides the device of a kind of building or the whole original position jacking of heritage buildings/group, for the method for above-mentioned building or heritage buildings/group's integral jacking provides technical guarantee.
The present invention still solves the technical scheme that its technical problem was adopted to meet the case explanation of true palace.

Three. the palace class is returned the whole original position jacking of type basis ancient building
Meet Zhen Gong palace and corridor, hall stylobate, comprise the dragon and tiger hall, thing side hall in a palace or temple, room, thing corridor, the residual location of Zhen Xiandian, group hall claustra stylobate.1.8 meters of dragon and tiger hall stylobates, 3.1 meters of very celestial hall stylobates, 1.6 meters of thing side hall in a palace or temple stylobates.Stylobate, room, corridor all around all the people present palace closely are connected to the type overall structure one time, actual situation folding up and down, and bilateral symmetry is rigorous, and front and back are in picturesque disorder.If true Xian Dian ruins, dragon and tiger hall, thing side hall in a palace or temple, group's hall claustra and stylobate are disassembled into single integral jacking monomer respectively, then meet Zhen Gong palace architectural complex and group hall claustra stylobate will be subjected to great destruction; For the integrality of protecting its structure and ancient times information authenticity, this programme is designed to a complete integral jacking monomer with true Xian Dian ruins, dragon and tiger hall, thing side hall in a palace or temple, group's hall claustra and stylobate.Do like this, very difficult, but for meeting the protection of true palace, may be best scheme.Meeting the whole original position jacking of true palace main shrine, side hall in a palace or temple and vestibule stylobate comprises following content and finishes construction by following order:
Reinforce climbing structure form reinforce system-→ make-up room in joist and laterally connecting on steel or the steel concrete, excavate indoor making steel or reinforced concrete upright column from top to bottom, following joist, laterally, oblique be connected to form framework joist system-→ the indoor and outdoor pile or enlarge the basis and establish foundation connection beam be connected to basis system-→ between framework joist system with the basis is, install jack-→ many jack, pipeline, oil pump, sensor and computer software and hardware constitute computer-controlled Hydraulic Synchronizing jack-up system (top power system)-→ in the hall around the basis fasten, the framework joist be both sides make some steel or steel concrete position limiting pile-→ make steel or steel concrete or concrete pad-→ a jacking/pad/jacking-→ build steel concrete fore-set or weldering/connect steel fore-set-→ weld/connect or build steel or steel concrete stub wall-→ fill out ram soil or scaffolding-→ jacking certain altitude level establish steel or steel concrete contact beam-→ repeat above-mentioned operation jacking reach design height-→ between grade beam and following joist damping device is being set or is being rigidly connected-→ the basis be and the framework joist be between filling, grouting-→ dismounting top power system, position limiting pile, reinforcing system-→ the arrangement recovery-→ periodic observation.
Position limiting pile), foundation underpinning system (comprising: pallet system or framework joist system), top power system, basis system (comprising: cushion block, stub) four major parts whole original position jacking technical scheme method of above-mentioned palace wall, palace door, palace and flow process, its common feature are to contain to reinforce system and (comprising:.Be described in further detail below in conjunction with meeting the whole original position jacking of true palace architectural complex.
Reinforcing system's (containing position limiting pile) is meant: in order to prevent excessive deformation and the damage of jacking building in the jacking process, guarantee the jacking job safety, to the structure and the basic interim strengthening measure of being taked of jacking building; As position limiting pile, be for prevent jacking building level to lateral drift, for making its rigidity big, generally adopt reinforced concrete structure; Palace gate arch circle is reinforced can adopt masonry and steel work; The palace reinforces can adopt wooden construction and steel work; Palace wall is reinforced can adopt wooden construction and reinforced concrete structure.
Foundation underpinning system is meant different foundation underpinning method and the structure that different type of foundations is taked; Palace wall basis is bar shaped, and in order to prevent deflection deformation excessive in the jacking process, pallet system lifts beam greatly and adopts steel concrete to build to form; Door basis, palace is rectangle Shitai County, rams soil in the platform, goes into a complete integral body in order to avoid excessive distortion in the jacking process in order to make it, and door foundation bottom complete underpining in palace is the steel concrete pallet; The design feature in palace generally is that the roofing load born of timber frame is lighter, and body of wall and Shitai County's base be from great, in order to alleviate jacking weight, can be in Shitai County's base from top to bottom base for post and stylobate be underpined and is the framework joist; If do not consider jacking weight, the palace foundation underpinning also can be taked the same method of palace door.
Top power system is meant that many jack, pipeline, oil pump, sensor and computer software and hardware constitute computer-controlled Hydraulic Synchronizing jack-up system.Meet the whole original position jacking in true palace 350 jack need be set approximately, be distributed under the palace door, palace wall, palace architectural complex of 45 mu of areas, require so many jack together to move synchronization of jacking up; Although existing computer-controlled Hydraulic Synchronizing jack-up system a complete set of equipment solves the Synchronization Control problem of meeting the whole original position jacking in true palace jack cluster, remain a difficult problem of not separating both at home and abroad.The key of a difficult problem is the economy and the integrity problem of resolution system; Existing computer-controlled Hydraulic Synchronizing jack-up system a complete set of equipment costs an arm and a leg both at home and abroad, adopts these equipment if meet true palace architectural complex jacking engineering, and total cost will rise at double, and then jacking scheme superiority will be lost to the greatest extent; Computer-controlled Hydraulic Synchronizing jack-up system is still common jack, there are several to go wrong in the hundreds of platform jack, in the jacking process, all may cause catastrophic consequence, especially list the national treasure level historical relic of World Cultural Heritage List as meeting true palace in, it is insecure that such system is adopted in jacking.
The thinking that the present invention solves its difficult problem is: if in many jack, because of one of equipment fault or part jack quit work, and another part must definitely be safe by the structure of jacking then still in operate as normal.Concrete measure by this thinking is the jack that manufactures and designs the special use of a kind of jacking building, and highly short and small, weight is frivolous, is beneficial to the jacking operation, and tonnage is determined by jack layout, tonnage, load, joist cross section and arrangement of reinforcement optimization; Its principal character is that the jacking range that this jack manufactures and designs is no more than the mid-span deflection value that jack span standard is allowed; Because the admissible value of Code for design of steel structures regulation common buildings flexural member amount of deflection is span 1/400-500, the admissible value of Code for design of concrete structures regulation common buildings flexural member amount of deflection is span 1/300-400; Suppose that the span that jack is arranged is 10 meters, then the standard mid-span deflection value of allowing is the 20-25 millimeter, and the jacking range that this jack manufactures and designs is 20 millimeters; When using this jack cluster jacking, if hindering for some reason, a jack quits work, the span of adjacent two jack quite doubles and promptly becomes 20 meters, then the standard mid-span deflection value of allowing is the 40-50 millimeter, the jacking range that manufactures and designs because of this jack is 20 millimeters, the actual span centre maximum immunity value of adjacent two jack this moment is 20 millimeters, also has one times safety stock, so be very safe and reliable with this jack jacking important building especially historical relic as the true palace of chance.Because of actual jacking design span can not be the same, for improving the versatility of this jack, the top lifting height trimmer that some ring-type steel sheets make can be set under jack jacking dish, around the lifting pin, on the oil cylinder, be used for adjusting the maximum jacking stroke of jack; Suppose that the jacking range that jack manufactures and designs is 20 millimeters, jacking is actual to require 10 millimeters, then needs 2 millimeters 5 of trimmers; Adopt this method, actual jack jacking amplitude can realize very little jacking amount, during this jack cluster jacking operation, jacking amount difference each other is very little, is not only as safe as a housely, and can be similar to and thinks synchronization of jacking up.
Adopt its jacking operation of this jack to be achieved in that every jack is passed through to adjust the jacking pad according to its load, span, set its maximum jacking stroke; According to its maximum jacking stroke, the billet of configuration certain thickness and quantity, the gross thickness of the billet of every jack configuration should be above 2 times of this jack overall height; According to the architectural complex top lifting height, dispose a considerable amount of steel or steel concrete or steel fibre reinforced concrete composite material cushion block, pad thickness equals the jack overall height, and cushion block is established and is given embedded part, is beneficial to cushion block welding or bolt; Between pallet beam and grade beam jack is set, installs repeatedly for avoiding jack, the jack adjustment is fixed under the pallet beam; Expect or concrete leveling with grouting above the grade beam and between the jack bottom surface that contiguous jack is placed a cushion block, and reserve the reinforcing bar jointing of stub; Artificial or electronic startup jack, and the jacking speed of control jack; When jack reaches maximum jacking stroke, between cushion block and pallet beam slit, fill in a billet; After inspection finished, jack slowly bounced back, and load passes on the grade beam by billet, cushion block; Fill in a billet in the slit below jack, repeat said process, billet above jack below, cushion block and jack overall height etc. are neat, and this moment, load passed on the grade beam by billet, cushion block; The billet that takes out the jack below is replaced by cushion block, starts jack, and load passes on the grade beam by jack, cushion block, and the billet that takes out pallet beam below is replaced by cushion block; The process of repeat above-mentioned plug steel plate, changing cushion block; Cushion block surpasses two, will weld rapidly or bolt each other, to increase rigidity and stability; Cushion block piece number or highly surpass certain numerical value as 0.5 meter, is then laid reinforcing bar around the cushion block, main muscle is reserved joint with grade beam and is connected, and upwards continues to reserve main muscle joint, and formwork erection is built from levelling rapid hardening high-strength concrete, jack below formation stub basis; Repeat above-mentioned plug steel plate, cushion block, build the process of stub, when pallet beam below headroom reaches 1.5 meters, scaffold erecting or the underfooting is filled out and rammed soil as scaffold, fill out and ram soil and simultaneously stub is worked the effect of going along with sb. to guard him; Repeat above-mentioned plug steel plate, cushion block, build stub, scaffold erecting or the process of ramming soil is filled out in the underfooting, until with the building jacking to design height, between stub and pallet beam damping device is set or is rigidly attached to simultaneously.Meet true palace architectural complex jacking and adopt to fill out and make scaffold on the rammer, and the buildings in general jacking is adopted and scaffolded erecting; The building jacking is to design height, and the jacking stub can be used as permanent frame column, also can reset frame column between grade beam and pallet beam, newly frame column is set after, the jacking stub can be removed.
Basis system comprises expansion basis, basic, the box foundation of pile cap, and is identical with the common buildings engineering, and execution conditions are difficulty relatively; The job practices of jacking stub as above saves described.
To meet the whole original position jacking technical scheme of true palace architectural complex be with the reconstruction technique scheme and build dam technical scheme a kind of new technical scheme arranged side by side.Meeting the whole original position jacking technical scheme of true palace architectural complex has drawn the reconstruction technique scheme and has built the advantage of dam technical scheme and avoided its shortcoming; the authenticity of meeting true palace and the integrality of Ancient Building Comoplex at Wudangshan total arrangement have been preserved on the spot; protected to greatest extent and met the information in ancient times of preserving in true palace and avoid destroying and losing, and provide a kind of new method for this type of ancient building or the protection of ancient buildings original position integral jacking.
The invention has the beneficial effects as follows: utilize method and apparatus provided by the invention, can realize meeting the whole original position jacking protection of true palace architectural complex (comprising palace wall, palace door, palace and vestibule stylobate) safely, economically; This method and apparatus also can be widely used in the lifting reconstruction of ancient building or ancient buildings and town and country existing building or architectural complex simultaneously.
