Description

The fast accurate installation method of large-scale space division device overall skid-mounted formula ice chest
Technical field
The present invention relates to the installing area of large scale equipment, specifically a kind of large-scale space division device overall skid-mounted formula ice chest it is fast The accurate installation method of speed.
Background technique
In recent years, promotion of the petrochemical industry to space division gas demand promotes gradually changing for making oxygen by air separation technology Into with it is perfect.Large-scale overall skid-mounted formula ice chest relies on its incomparable huge advantage in terms of construction quality, safety, progress, It is increasingly becoming the mainstream of large-scale space division device, new challenge also is proposed to the reform of construction technology.Large Air Separation Devices entirety ice chest Not only specification is big, quantity is more for the fixed foundation bolt used, requires also very the whole precision between foundation bolt Height, the offset of any one foundation bolt all can cause whole ice chest in place.And cold box foundation pour vibrate, concrete support Shield is shunk and the strange land of ice chest bottom plate processes the uncontrollable offset that can all lead to foundation bolt or bolt hole.
In existing traditional construction technology, usually using design drawing as foundation, on the one hand in cold box foundation construction, by force The installation accuracy and stability of pre-embedded anchoring bolts are adjusted, the positioning of reduction bolt, concrete vibrating and maintenance as far as possible was shunk Installation deviation in journey.On the other hand, it is desirable that composing room carry out the fabrication and installation of ice chest bottom plate when, bed bolt hole site with set Meter requires the high accuracy of position.The deformation generated in control welding and installation process as far as possible.But either cold box foundation is applied Foundation bolt deformation during work or the welding deformation in ice chest bottom plate assembling process, all have very strong uncontrollability, Once it is cumulative deflection occur, will lead to whole ice chest can not be in place.If continued to increase to the two deformation amount controlling requirement, It will cause the increased costs of geometry times.And relative to the deviation requirement between the two and design drawing, whether whole ice chest can Fast accurate is in place, and it is accurate right between ice chest bed bolt hole and cold box foundation pre-embedded anchoring bolts group that more aspects are It should be related to.
Summary of the invention
It is an object of the invention to overcome drawbacks described above, providing one kind can ensure that ice chest is in place, and bed bolt hole is smooth Be put into foundation bolt, complete the fast accurate of whole ice chest method in place.
In order to achieve the above object, the present invention is implemented as follows:

Step 7 checks ice chest column root-plate hole location according to again assembled positioning measurement mold;
Step 8, ice chest bottom plate are marched into the arena review;
Step 9, whole ice chest adjust in place;
Wherein,
Cold box foundation foundation bolt position mark in step 1 is on cold box foundation bed course, using total station or other benchmark Measuring tool, according to cold box foundation cushion cap floor plan by each foundation bolt position line setting on bed course, it is desirable that every Catercorner length is surveyed between two foundation bolts and design requirement error is not greater than 2mm;
The fixed support of ice chest pre-embedded anchoring bolts in step 2, is to use angle steel after foundation bolt straightening in place, will to each group Reinforcement is fixed in foot bolt point upper layer and lower layer, controls every group of inner bolt relative position by determining hole steel plate, it is desirable that every group of bolt Between relative position deviation be not more than 7mm;
Cold box foundation in step 3 pours maintenance, concrete vibrating and basic maintenance contraction distortion when being to cold box foundation construction It is controlled, after cold box foundation reaches curing condition requirement, foundation bolt fixation steel plate can be removed;
Cold box foundation pre-embedded bolt positioning measurement mold in step 4, consider convenient transportation, reinforcing bar set a roof beam in place can a point three parts combine Splicing, and steel seal number is marked for distinguishing on truss-steel beam, wherein mould steel framework beam is for measuring record cold box foundation each group Relative position between foundation bolt, mould template are used to measure the relative position in record each group between foundation bolt;
In step 5, mold truss-steel beam is in place by figure requirement first, mould template is then put into foundation bolt;Use steelframe Beam holds up mould template from bottom, adjusts mould template surface in the same horizontal absolute altitude, template is weldingly fixed on truss-steel beam On, after weld seam natural cooling, check adjusts all templates on the same horizontal plane absolute altitude again;
In step 6, positioning mold is integrally hung out to foundation bolt position, is placed on ground grading, checks each component number of mold, And the diagonal bolt hole in repetition measurement part away from data and draws schematic diagram record, in case ice chest checks bed bolt hole after marching into the arena;Remove mold Bolt is connected, template is returned into ice chest composing room;
In step 7, workshop is bolted assembled mold, and according to diebolt according to steelframe beam assembly connecting plate groove position Hole site makes ice chest bottom plate;
In step 8, after ice chest is marched into the arena, ice chest bed bolt pitch of holes is checked, is further ensured that ice chest bed bolt hole and ice chest The accuracy of basic foundation bolt;
Ice chest lifting in step 9 is in place, after determining ice chest installation direction according to ice chest drawing, arrange special messenger to every group of bolt into Row nurse adjusts ice chest screwhole position by tools such as scaffolding steel pipe, flitches, while ice chest being kept to stablize, to all bolts It is slowly in place when corresponding screw hole.
The accuracy and stabilization of pre-embedded anchoring bolts when this method ensures that cold box foundation is constructed by angle steel fixing support rack Property, effectively prevent vibrate deformation and the contraction distortion in concreting and maintenance processes.Meanwhile whole ice chest lower margin spiral shell The use of anchoring position Measurement die, which can accurately react cold box foundation foundation bolt relative position, gives ice chest composing room, guarantees The accurate positioning in ice chest bed bolt hole, the bed bolt hole repetition measurement after ice chest is marched into the arena then further ensure that ice chest is disposable Accuracy in place;Ensure that the safe and efficient smooth lifting of skid-mounted type ice chest is in place, greatly reduce in hoisting process there may be Bottom plate reaming risk, ensure that ice chest precisely it is in place safely and fast.
