The specific embodiment:
It is that various prefabricated caisson type devices are sat heavy essential elements of laying in the foundation construction equipment that equipment loads with operation ship, and the equipment loading is driving cabin and personnel residential community with the forefront of operation ship like this, follows and stirs and conveying device (2) by cement slurry.
That lays submersible type pile foundation and column making apparatus lays platform (4), preferably be produced on stern, and for increasing tall and big submersible type pile foundation and column making apparatus, stability in transportation, submersible type pile foundation and the column making apparatus on the quarter made are laid platform (4), preferably will the height decrease such as figure.
Hang the crane (3) of the special-purpose pile driver of submersible type pile foundation and column making apparatus and submersible type etc., generally in the fore-body surface making of laying platform (4) near submersible type pile foundation and column making apparatus.And between the cement slurry stirring and conveying device (2) of crane (3) and front portion, then make the materials such as the very large cement of the degree of depth, sandstone, reinforcing bar, and cement collar tie beam formula foundation is made the storage space of mould.
Topmost in such material storage space is manufactured with the foldable cover that two sides ride over side of a ship position.Such foldable cover when folding packing up upwards, the intermittence space that forms between folding cover plate, can be used for that the material such as sandstone loads from cargo ship to equipment and operation ship in conveying.And after these folding cover plate sets level, then can place at an upper portion thereof the special-purpose pile driver of submersible type, or make cage of reinforcement (44) in the cement collar tie beam of laying prefabricated caisson type device basic, and the collar tie beam formula foundation making mould of making cage of reinforcement (44).
On equipment loading and operation ship, make cement slurry except need and stir with conveying device (2), crane (3), submersible type pile foundation and column making apparatus and the special-purpose pile driver of submersible type and lay the platform (4) etc., also should be made as the compressor of submersible type pile foundation and column making apparatus and submersible type special use pile driver ventilation; And be various motors in the special-purpose pile driver of submersible type pile foundation and column making apparatus and submersible type, the generator, hydraulic pump, pulsometer of operation power etc. are provided; The cement slurry that stirs is transported to submersible type pile foundation and column making apparatus, or cement collar tie beam formula foundation is made the conveying device of carrying cement slurry in the mould.
Load above the submersible type pile foundation of carrying with the operation ship rear portion and the column making apparatus on the building berth at equipment no matter be, or on the hull above the special-purpose pile driver of the submersible type of parking in crane the place ahead, all should be as seeing in Fig. 1, make the fixedly fastening devices (46) of submersible type pile foundation and column making apparatus or submersible type special use pile driver.
Load submersible type pile foundation and the column making apparatus that carries with the operation ship rear portion at equipment, see it is to import and export, can promote that various motors move in submersible type pile foundation and the column making apparatus by the material that the personnel that do not paint in disk (6), submersible type pile foundation and column making apparatus vertical operation spatial enclosure (7), air chimney (16) and the figure and various needs are stablized in the bottom of submersible type pile foundation and column making apparatus from appearance, ajutage or hydraulic oil carrier pipe and power line, cement slurry input port etc. are common to be consisted of.
Stablize the below, four mutual equidistant positions of disk (6) periphery in submersible type pile foundation and column making apparatus bottom in addition, but four folding and unfolding sea-anchors that link to each other with longer cable wire also can be set.So that at submersible type pile foundation and column making apparatus, hang onto position, the seabed process of islands and reefs reef dish downwards, can help submersible type pile foundation and column making apparatus by being put in advance the mutual tractive of sea-anchor of seabed different parts on every side, carry out the accurate location of pile foundation and column production location
Ground column and pile foundation manufacturing process in prefabricated caisson type device is laid the basis, for helping pile foundation and column in submersible type pile foundation and the column making apparatus, production location is accurately located, near the top of submersible type pile foundation and column making apparatus, two very large searchlights of luminosity of installing with the 90 degree angles of cut are set.And at the height and position close to each other with searchlight, make and observe and measured hole.Meanwhile on the ground pile foundation that has completed and column, add irritability fluorescence and generate material or light reflector.Stablize within the disk (6) in submersible type pile foundation and column making apparatus bottom in addition, also should be similar for radio antenna with past tense with two of the complete equidirectional making of searchlight, the scalable distance measurement bar of rod-pulling type of the angle of cut 90 degree.So just can be by the cooperatively interacting of these measurement mechanisms, finally make each prefabricated caisson type device lay ground column and pile foundation in the basis, all under the condition of more accurate location, make forming.
And inner in submersible type pile foundation and column making apparatus, be submersible type pile foundation and column making apparatus internal work space (30).And in such device interior working space, then exist to make to extend to the drilling well facility that upright post basic is used on the surface, seabed from depths, stratum, seabed, reinforced concrete ground column making apparatus is with the piling facility of squeezing into the steel pipe pile foundation toward the seabed earth formation deep.Stablize in disk (6) district at submersible type pile foundation and column making apparatus and special-purpose pile driver in addition, also be manufactured with the water storage cabinet of help equipment lifting in seawater.
Wherein making the drilling well facility that extends to upright post basic on the surface, seabed from depths, stratum, seabed, be by air pressure, hydraulic pressure or electro-motor (8), drill bit (9), drilling rod (10), the outer casing (11) of drilling rig, can to open with the locking device that seals outer casing bottom opening (12), outer casing top seal device (47) be main making.The drilling well facility take drilling rod, outer casing etc. as the master like this is when carrying out work, then by at first being positioned at submersible type pile foundation and column making apparatus bottom, can open with the locking device that seals outer casing bottom opening (12) and open, and then by outer casing top seal device (47) power transmission, promote outer casing (11) drilling rod (10) inboard with it of drilling rig, and the drill bit (9) of drilling rod bottom together, creeps into to the earth formation deep of islands and reefs reef panel surface.
Casing (11), drilling rod (10) and drill bit (9) etc. are main whole drilling well facility in addition, it creeps into downwards in the deep formation of seabed, bore so mobile power resources under the drill bit, can provide by air pressure, hydraulic pressure or electro-motor (8).But preferably adopt special-purpose CD-ROM drive motor (23) to provide.And promote the power resources of these motor operations, then can be loaded with operation ship by equipment fully equally provide.
The concrete grammar that moves up and down as for such drilling well facility, can be as Fig. 4,6 interior draftings, use is casing (11) outside outside drilling rig, that installs promotes central drilling well facility lifting ratch (24), and the tooth bar that exists with the outer casing of drilling rig surface interacts to provide.Equally also can as Fig. 4,6 interior, the swing pinion that adopts casing top seal device (47) position outside to install interacts and provides with the central drilling well facility lifter rack (24) that promotes of casing arranged outside outside.Certainly also can be as drawing in Fig. 5, with the formed rotary power of special-purpose CD-ROM drive motor (23), the top seal plate (18) that is sent to submersible type pile foundation and column making apparatus top by power transmission pole (21) is the position up and down, pass through again the effect of top gear train (22), with such rotary power, convert liftable ratch (20) lifting drive with the interconnective drilling well facility of whole drilling rig center of top to.In addition can also be as drawing in Fig. 5, by the hydraulic-driven power from equipment loading and operation ship, the interior bar of top hydraulic means (26) that promotes to be connected with drilling rig moves, and promotes the drilling well facility and moves up and down.
Within the casing (11), also be manufactured with for the seawater of removing deposit that drilling process produces and be blown into pipe outside the drilling rig in submersible type pile foundation and column making apparatus, with the outer comb that will be cleared up the outside power discharge of sea bed material.And the two extend upward the position, all be at first to pass top outer casing top seal device (47), and then extend to outside the scope of whole submersible type pile foundation and column making apparatus.The seabed reef panel surface material that drilling rig bottom bit cleans out, by with seawater be blown in the pipe be blown into sea water mixing after, just can be by by the outer comb discharge of cleaning material.
In order to be conducive on the very rugged surface, islands and reefs reef dish seabed of morphosequent, make some at seawater inner height and bottom, ground, the seabed ground column that all development length is larger, so within submersible type pile foundation and column making apparatus, the outer casing (11) of drilling rig and drilling rod (10), preferably all being made as can be by interconnecting the structure that prolongs.Locating detent adjustable height control screw rod (14) also is preferably designed as and can passes through to connect the structure that prolongs in addition.
Some position, surface at islands and reefs reef dish, the accumulation of thick such as more open coral and sandstone, when the position makes the ground column like this, just can not be with the bottom of ground column, get into down the islands and reefs basement rock position with competent bed always, so at the such foot of hole at position, just can only increase in the pile foundation of further squeezing into subsequently the part steel pipe intensity of lower part ground.So within submersible type pile foundation and column making apparatus, also be provided with by some piling devices such as the stand-by pile foundation pipe of deposit (28) of the pulley (17) that uses behind rotatable 90 degree, gravity drop hammer (27), drag cable (29), reef dish earth formation deep to be squeezed into, the device that the pile foundation pipe is positioned in the casing outside, hoist engines.
But carry out lower brill from wanting deep, column below foundation pit, when being transformed in the ground datum hole that has got out further the driven pile parent tube, should be at first to decomposing being connected between part or the nearly outer casing (11) that all stretches into down submersible type pile foundation and column making apparatus bottom and the outer casing top seal device (47), then outer casing top seal device (47) is extracted by upwards promoting with drill bit (9) together with the drilling rod (10) of below in it, and removed the drilling rod (10) and drill bit (9) of outer casing top seal device (47) below.And then in the outer casing that has not had outer casing top seal device (47), put into bottom the to be squeezed into pile foundation pipe that includes pile foundation pipe positioner, behind pulley (17) 90-degree rotation that the top can be arranged with that again, start again the hoist engine equal power device and drive gravity drop hammer, pile foundation pipe in the outer casing is constantly squeezed into the depths, stratum of islands and reefs reef panel surface, until pile foundation pipe bottom invades the certain depth position of earth formation deep, or invade down till the basement rock position of earth formation deep always.
And exceed cement post process on the plane, seabed in the making of islands and reefs reef panel surface, and then be to finish the lower brill of upright post basic, with in the column foundation ditch that carries out lower brill formation, further squeezed into increase foundation strength steel pile tube pile foundation and just begun to carry out afterwards.Its concrete preparation method is, at first in the outer casing that still is present in the column foundation ditch, put into the cage of reinforcement of making in advance, and then will squeeze into the outer casing top seal device (47) that the steel pipe pile process has been removed, reconnect the top that is fixed to outer casing (11), and will originally down bore column foundation ditch process, once used seawater was blown into pipe and was extracted by cleaning sea bed material discharge pipe, therefore and one of opening that forms from, that evenly arranges puts into the many cement vibrating spears that can always reach down outer casing (11) bottom, puts into the cement slurry carrier pipe at another opening part simultaneously.After just can mentioning one section outer casing (11) again, just by in the space of vacating toward its underpart, send into cement slurry and vibrate to make one section upright post basic.Rise to till the top of islands and reefs reef panel surface upright post basic of designing requirement always.
But on the upright post basic top that upwards reaches the surface, seabed, as also continuing to be produced on further upwardly extending column fragment in the seawater, then outside between the cage of reinforcement and outer casing (11) in the casing (11), just need further to add the lining of being close to outer casing (11) that a sheet iron and so on material is made, and then send into cement slurry make one section extend upward column after, upwards mention one section outer casing (11), until reach till the column height that needs.
In fact the prefabricated caisson type device itself that designs because of the author, mostly has larger volume and buoyancy, and these devices are dragging when wanting riding position, will be by in this sampling device, injecting a certain amount of seawater, just they can be sat the heavy seabed that is placed to islands and reefs reef panel surface, so as long as there is the removable seawater can form lift, then they are just not too large to the pressure of position, seabed, the below steel pipe pile pile foundation that will lay them or reinforced concrete column below so prefabricated caisson type device.Thereby such as the prefabricated riding position of caisson type device in islands and reefs reef panel surface seawater, so long as in the seabed or the near Sea Bottom position, and the submarine geomorphy of islands and reefs reef panel surface is also relatively smooth, just can only adopt fully toward islands and reefs reef panel surface, squeeze into a large amount of steel pipe pile pile foundations, make prefabricated caisson type device and sit heavy basis.And rising and falling little islands and reefs reef panel surface, and also can make by the higher part position in the seabed steel pipe pile pile foundation, and make the reinforced concrete column at the shorter position in seabed, jointly make prefabricated caisson type device foundation.Thereby lay in the basic making apparatus at the author's prefabricated caisson type device, also designed the submersible type special-purpose pile driver of Fig. 9,10 interior draftings.
In the machine of the special-purpose pile driver of submersible type in the space, the pile driving rig that has is hoist engine of not drawing in pulley (17), gravity drop hammer (27), drag cable (29), Fig. 9,10 and so on power set too, surpass and need length pile foundation pipe cutter sweep, pile foundation pipe top big diameter disc welder etc.And in the special-purpose pile driver of such submersible type, also should lay in the in a large number stand-by pile foundation pipe (28) of reef dish earth formation deep to be squeezed into.And near the top of the special-purpose pile driver of submersible type, also should make air chimney (16).And in the position near the top, two high luminosity searchlights of installation that mutual 90 degree intersect.Stablize within the disk (6) at the special-purpose pile driver of submersible type, also answer installation that 90 degree intersect to make two measurement loop bars with searchlight class radio telescopic antenna in the same way, and stablize the periphery of disk (6) at the special-purpose pile driver of submersible type, make by the common submersible type special use pile driver height control system that consists of of locating detent (13) and locating detent adjustable height control screw rod (14).Yet need simultaneously to stablize four equidistance peripheral positions of disk (6) at the special-purpose pile driver of submersible type, but four folding and unfolding sea-anchors that are connected on the longer cable wire are set.And in the special-purpose pile driver of submersible type stablize disk (6) district, also make the water storage cabinet of controlling the lifting in seawater of special-purpose pile driver.
And the special-purpose pile driver of submersible type pile foundation and column making apparatus or submersible type, before in hanging onto seawater, positioning placement, should be first by the annular movement of equipment loading with operation ship, first submersible type pile foundation and column making apparatus or the special-purpose pile driver of submersible type bottom stablize the sea-anchor below the disk (6), be placed into the certain distance position on every side, position of to drive piles, then by the movement of equipment loading with operation ship, be connected with the sea-anchor tractive of cable wire, class radio telescopic antenna type under the searchlight irradiation is measured loop bar and is accurately measured, the correct movement and the location that help the special-purpose pile driver of submersible type to carry out, finally make each steel pipe pile pile foundation pipe, all squeeze into very accurately the specific needs position in seabed.
As for the concrete manufacturing process at steel pipe pile pile foundation pipe; should be screwed at the top of steel pipe pile pile foundation pipe first and impact the protection head; mounted steel pipe pile pile foundation pipe is being driven underground substantially; and when also not reaching the projected depth that steel pipe pile needs; that should back out top impacts the protection head; then be screwed into new stand-by pile foundation pipe on the top of steel pipe pile pile foundation pipe and impact the protection head; again use again drag cable (29) pull-up gravity drop hammer (27) to continue to begin to impact; until the subordinate reaches the degree of depth that needs under the steel pipe pile pile foundation pipe, or arrive till the basement rock position in deep, seabed.And steel pipe pile pile foundation pipe will reach need the degree of depth after, adopt cutter sweep to prescind the residue pile foundation pipe on the steel pipe pile pile foundation pipe large load-bearing disk in top (61) top, and make it to weld with the steel pipe pile pile foundation pipe large load-bearing disk in top (61).Then just can in the steel pipe pile pile foundation pipe large load-bearing disk in top (61) installing hole, the new steel pipe pile pile foundation pipe large load-bearing disk in top (61) and steel pipe pile pile foundation pipe be installed.Then after opening removable device for opening (60), the pile foundation pipe of the steel pipe pile pile foundation Guan Ding bottom by top and the large load-bearing disk (61) on top, it is finally got to leave the special-purpose pile driver of submersible type, and arrive the degree of depth in the stratum, seabed that stretches into that needs.
In the designed various prefabricated caisson type device of the author, the overwhelming majority be should sit end property be placed in islands and reefs reef panel surface, thereby in so prefabricated caisson type device riding position bottom, except the very large rugged especially position of Partial Height fluctuating, only need generally speaking the surface at the islands and reefs reef dish in seabed, the basis that makes simple column or steel pipe pile foundation gets final product, and not necessarily must make the foundation with horizontal gird structure.But in sea water advanced king-sized islands and reefs reef panel surface (such as the Zhongsha Islands, Zengmu Reef etc.), or sea bed surface, sea water advanced very large coastal waters (being necessary to lay prefabricated caisson type device sea bed such as in the East China Sea and the Yellow Sea some), when making some prefabricated caisson type device basics such as ring-type or the prefabricated caisson type personnel of common unit building formula residential building, for the underwater penetration that lowers prefabricated caisson type device bottom to improve safety.And at the very large rugged especially position of some earth's surface height relief of islands and reefs reef panel surface, when making various prefabricated caisson type devices and laying the basis, in order to increase the stability of laying the basis, prefabricated caisson type device bottom foundation in these two kinds of situations, as be made as top and have the interconnective collar tie beam formula of crossbeam structure, all can be so that the stability of foundation and load-bearing property be better.Even and in the seabed milder general islands and reefs reef panel surface, the prefabricated caisson type device foundation that end property is laid is sat in making, as be made as top and have the interconnective structure of crossbeam, also can make the stability of foundation higher, so in these several situations, just all must consider to make the mould support by collar tie beam formula foundation, make top and had the prefabricated caisson type device of the interconnective collar tie beam formula of crossbeam foundation.
When top has the making of the prefabricated caisson type device of the interconnective collar tie beam formula of crossbeam foundation, as the prefabricated caisson type device of collar tie beam formula foundation, when the surface of being close to islands and reefs reef dish makes, can adopt collar tie beam formula foundation in Figure 12-14 to make mould structure and make.As in the seawater that leaves islands and reefs reef panel surface, when making prefabricated caisson type device and laying the basis, then can adopt collar tie beam formula foundations in Figure 15,16 to make mould structures and make.
The interconnective collar tie beam formula of top tool crossbeam foundation is made mould, is by the upper mould (31) of making mould, make two side templates (32) of mould, make mold bottom template (33), axis of rotation (34), bottom fixing templates (35), further and the knob of fixing two side templates (36), further and the screw rod of fixing two side templates (37), cement vibrator (38), cement vibrator base plate (39), cement vibrator base plate elevating control knob (40), strut the knob (41) of bottom template, strut the screw rod (42) of bottom template, two side template suspension arrangements (43), the lower bolster (54) of collar tie beam body bottom will be retained in, Liftable type mould urceolus (55), liftable supporter (56), make mould and place levelness rotation regulating rod bottom (57), class hinge rotary body (58), liftable supporter top connector (59) is main formation.
Have the interconnective collar tie beam formula of crossbeam foundation on top and make mould top, also should install itself and equipment load and operation ship between cement slurry stirring and the conveying device (2), the cement pipe that mutually connects.Also should install collar tie beam formula foundation and make mould and make local collar tie beam connecting portion, the needed light fixture that thrown light on when mutually docking under water, and can the underwater observation image be sent to equipment load with operation ship on camera.Furthering and the knob of fixing two side templates (36) in Figure 11-16, and cement vibrator base plate elevating control knob (40), although all can operate by diver's handwork, but preferably on these knobs, install flywheel and chain additional, couple together with power drive system again.As for its work required drive, can be the effect of screw mandrel and gear etc. by provide the moving motor of air pressure, hydraulic pressure or the electricity of power to reach being connected with it by equipment loading and operation ship, be delivered among the power drive system that links to each other with two kinds of knobs.
And in the foundation actual fabrication process of collar tie beam formula, should at first make needed special-purpose the making in the mould of such foundation, install the internal lining pipe that sheet iron or thicker plastics and so on material is made additional, and in such internal lining pipe, install simultaneously cage of reinforcement (44) in the crossbeam additional, and cooperatively interact with the screw rod of fixing two side templates (37) etc. and act on furthering by furthering of installing simultaneously and the knob of fixing two side templates (36), so just can be assembled and form make the reinforced concrete collar tie beam, the reinforced concrete collar tie beam formula foundation with certain area makes mould.Subsequently such Combined type reinforced cement collar tie beam is being made mould, hang onto make steel pipe pile pile foundation or cement post want riding position after, just can by the cement of in such collar tie beam formula foundation is made mould, annotating, make top and have the interconnective collar tie beam formula of crossbeam foundation.
Has the interconnective collar tie beam formula of crossbeam foundation making mould top, should make clamping ring beam type foundation and make that mould and equipment loads with operation ship, cement slurry carrier pipe Active Interface, also should collar tie beam formula foundation make mould top from different cement slurry carrier pipes, the cement slurry of the carrying mould template position, position of mutually confluxing, and collar tie beam formula foundation is made the position, top of mould, make the poroid dewatering orifice of some class sieves, and for sending device under the cement slurry carrier pipe making cement slurry pressure, in order to make the cement slurry that flows into space in the collar tie beam formula foundation making mould template, can be full of whole collar tie beam formula foundation fully and make die space.
The various prefabricated caisson type device floor space and the volume that design because of the author are all very huge, so generally speaking, we can not just make a great collar tie beam formula foundation quickly and make mould, and the disposable foundation that hangs the seabed will make riding position, makes the prefabricated caisson type device of the collar tie beam formula foundation of a fully integrated property.But can only with the complete prefabricated caisson type device of collar tie beam formula foundation, be divided into a plurality of localities zone and make successively.So just must be each made foundation segmentation and will make between the foundation segmentation next time, making can interconnective linkage.Can interconnect so a wherein side connector of device, it is cage of reinforcement (44) end points in the reinforced concrete crossbeam that completes, but weld the steel plate that the whole collar tie beam formula of a shutoff foundation is made the mould port, and the outside of this steel plate near middle further many of welding than bar reinforcement, and with the rectangle bar reinforcement circle of the inboard welding of these bar reinforcements, form together the interpolation type connector of the rectangular-shaped distribution of class.As for interconnective with such interpolation type connector, be positioned at collar tie beam formula foundation and make the jacket-type connector of mould, the diameter of its connector inboard is identical with the diameter of cage of reinforcement (44) in the present crossbeam, but should further add side by side many bar reinforcements in such rectangle cage of reinforcement inboard equally, and with its outside many welding rectangle bar reinforcement circle, be made as a jacket-type connector that can be enclosed within the reinforced concrete crossbeam end points interpolation type connector outside that completed.
Although the manufacturing process in cement post and steel pipe pile pile foundation, we can accomplish to want so that different cement post and steel pipe pile pile foundation overhead height are consistent with each other as far as possible, in any case but different cement posts and steel pipe pile pile foundation top, still can there be some differences in height, so make the mould installation course at such collar tie beam formula foundation, should be according to the result of accurate measurement, be adjusted at each special cement column and steel pipe pile pile foundation top, the collar tie beam formula foundation of parking is made mold height, finally makes the upper surface maintenance level of the prefabricated caisson type device of the collar tie beam formula foundation making mould that completes.
For as much as possible the making in the mould toward collar tie beam formula foundation filled cement slurry, make toward collar tie beam formula foundation in the mould before the perfusion at cement slurry, should promote by cement vibrator base plate the rotation of knob (40), make collar tie beam formula foundation make the cement vibrator base plate (39) at mould top, rise to position, mould inner top the top.And after finishing the filling process of cement slurry, then promote knob (40) by the cement vibrator base plate of outwarding winding, make cement vibrator base plate (39) can be arbitrarily movable with descend, like this with regard to so that cement vibrator (38) but freely-movable finish and vibrated the effect of cement slurry.
When making the collar tie beam formula foundation of various prefabricated caisson type device installation site, should adopt the comparable cement material that faster condenses.So just can when the collar tie beam of finishing whole ground basic parts is made, solidify through the cement slurry than blink, just can carry out after the form removal special-purpose collar tie beam perfusion making mould re-started and recycle.
After the cement slurry rapid condensation in the collar tie beam formula foundation, remove collar tie beam formula foundation and make the form removal method of mould, then be to promote knob (40) by significant rotary cement vibrator base plate first, the cement vibrator base plate (39) that cement vibrator (38) is installed is promoted, separate with Manufactured collar tie beam formula foundation upper surface, and then significantly outward winding and further and the knob of fixing two side templates (36), making furthers separates with the screw rod of fixing two side templates (37) with furthering with the knob of fixing two side templates (36), and in rotatable collar tie beam formula foundation making mold bottom template (33) limit section of opening, leave two side templates (32) the bottom fixing templates (35) of making mould simultaneously, the knob (41) of significant rotary opening bottom template, make the screw rod (42) that struts the bottom template by moving down, cause collar tie beam formula foundation making mold bottom template (33) to begin to open by the rotation of axis of rotation (34) downwards, again subsequently just can be by the traction of loading with work ship-mounted crane (3), collar tie beam formula foundation is made mold hoisting be put into the top of loading with workboat, the cage of reinforcement (44) in the crossbeam of side installation is within it prepared to have reused again.
