The structure with the backfilling can support such as roads or rails.
Description
The application is that application number is 93108246.3, the applying date is on July 8th, 1993, be entitled as the dividing an application of application of " domes ".
The present invention relates to domes, the method for building this structure and some member of this structure.
As can be known, a kind of domes comprise many precast concrete rib shape members of arranging along the structure length direction from Japanese patent application No.62-9196.Member is divided into first row and second row, and they all are bearing on the base with separately footing, and first row's member and second is arranged the dome portions tabling of member in structure.At the vault place, first row's member has the right area supported of a lateral face, and this area supported is generally the right surface of the lateral face that is generally convex spill and that be used to admit second row's member.
Therefore, Japanese patent application No.62-9196 has disclosed a kind of arch structure constructing method, and this method may further comprise the steps: first row and second row that many members are positioned to meet at the structure dome portions along the structure length direction.But how this patent carries out backfill to these domes if not disclosing.
The object of the present invention is to provide a kind of can the minimizing possibility in crack to occur because of the domes natural subsidence makes domes.
From an aspect, this invention provides a kind of method of building a kind of domes, and it comprises the following steps: along the structure length direction first row and second that many members are positioned to meet at the structure dome portions to be arranged; Be characterized in by in a perithallium of abutment structure, limiting the not compacting of backfill in one first back filled region and this district, and, the backfill in this district is carried out compacting come domes are carried out backfill in a perithallium of first back filled region, limiting one second back filled region.
From another point of view, this invention provides a kind of domes, and it comprises many first row and second row's members of arranging along the structure length direction, and two rows are compiled in the vault place of structure mutually; The such backfill of this structure: first back filled region is positioned at a perithallium of abutment structure, its backfill and not compacting in construction, and second back filled region is positioned at the perithallium in abutting connection with first district, and backfill and compacting in construction.
The natural subsidence that backfill in compacting first district can hinder domes, and under serious situation, can make member produce the crack.Therefore the present invention has the advantage that can prevent these problems.Such as, domes generally are used for building tunnel or culvert, and backfill then can support road or railway.
Preferred methods comprises the backfill in slight compacting second district.In general, be that the compacting equipment that adopts weight to be no more than 1500 kilograms comes slight compacting second district.Such as, can adopt the pusher compacting equipment of walking, such as pusher vibratory roller of single/pair roller walking or the pusher vibratory plate compactor of walking.Adopt this class backfill way, can avoid member that unnecessary motion takes place.Especially, slightly compactioncan prevents that member displacement and uneven loading are in structure.
First and/or second district can be reduced to less vertical thickness to the vault place at the horizontal breadth at pier place.In a preferred approach, the thickness in first district reduces gradually to the vault place, and the thickness in second district remains unchanged from the base to the vault.In another preferred approach, the thickness in first district remains unchanged from the base to the vault, and the thickness in second district reduces to vault.Typically, the horizontal breadth of first district at the pier place can be 0.4 meter, and the horizontal breadth of second district at the pier place can be 1.6 meters, and can be decreased to 0.6 meter at the vault place.
Preferably come the backfill domes by regulation one the 3rd district outside second back filled region, the 3rd area definition is between two vertical planes that are parallel to the structure length extension of the both sides that lay respectively at structure, and be positioned on the external boundary in second district on the structure essential part or outside, heavy ground of the backfill compacting in the 3rd district but do not apply vibration.In general, be to carry out heavy compacting with the road roller that has the driver to sit onboard of weight above 1500 kilograms.Also can come further backfill domes, and carry out heavy compacting with the filler that vibrates the 4th district by regulation one the 4th district outside the vertical plane of the 3rd back filled region.Therefore can adopt a vibratory roller to the 4th district.
Preferably, to all compacting zone, backfill is densified to 95% of standard Pu Shi density (SPD).
Backfilling material can be selected according to the available material in locality, but preferably is divided into specifications such as several.Preferably, in a perithallium of abutment structure, be specified in a bulk goods back filled region.
Preferably, the external boundary with the bulk goods back filled region is positioned between the external boundary in first and second districts.Can be outside this zone with needing not to be other granular backfilling materials.Like this, for example, can adopt local available material, as long as it contains MIN clay.In general, the maximum particle size of granular materials is 150 millimeters.The preferable classification specification of granular backfill is as follows:
Screen size % throughput
150 millimeter 100
75 millimeters 75-100
0.075 millimeter 0-1 5
Granular materials backfill zone can reduce to vault at the horizontal breadth at pier place, is half of horizontal breadth of base position such as the vertical thickness at vault place.Perhaps, the thickness of granular zone remains unchanged from the base to the vault.Such as, the thickness of base position can be 1.0 meters, no matter whether this thickness reduces to vault.
For fear of excessive eccentric load is arranged on domes, preferably the backfill of structure both sides during backfill in the difference in height in any moment all remain minimum.And difference in height preferably is no more than 0.5 meter.
At least in this preferable earth-filling method, the relative displacement between the adjacent members or its potential energy can be dropped to minimum.And, also can limit the sedimentation of backfill self.
Preferable is that the member and second member of arranging that member are positioned to first row longitudinally stagger.So just do not need with the whole width of vertical connector extension in domes, this has improved the intensity and the stability of structure.And, during building, in case first of relative two rows and second member are correctly located, the relation that staggers just provides a longitudinal edge that exposes at the vault place, next member just can be against locating thereon, and the placement of this member and subsequent members is just very convenient like this.Therefore, first and second member can help the 3rd member location, and the 3rd member can help the 4th member location again, and the rest may be inferred.
Member usually should be with the crane gear hoisted in position that changes wall crane and so on, and for this reason, member is preferably in the suitable inlet part of concrete embedded set or hanger so that connect suspender when prefabricated.In case first and second member location finish, they just can self be supported and can break away from crane gear.Therefore, in a preferred approach, one group of initial member is to position with first and second crane gears, and one group of follow-up member only positions with a crane gear.This means, only need two crane gears in the starting stage of construction, only need a crane gear (or first or second) to finish assembling subsequently, this has just saved expense.Initial that group can include only first and second member, and these two members are that self supports, but want when locating follow-up member enough carefully.In some cases, for greater safety, preferably keep first or second member to be connected, after the 3rd and the 4th member location, decontrol first or second member again with its crane gear separately.Like this, that initial group just comprises first, second, third and the 4th member will installing.In two kinds of situations, domes generally all are made up of many members, so most of member all is with a single crane gear hoisting and locating.
For the both ends that make domes end at single position, rather than, be each end that a vertical width is positioned domes corresponding to the member of longitudinal biasing amount and one step, a kind of preferred approach are arranged at the vault place because of the relation that staggers.The longitudinal biasing amount can be selected in the scope less than the vertical width of member, but half of member width preferably.In general, all member all is a same widths, has only the member exception at both ends.
A kind of preferred methods comprises the following steps: to locate first member of first row; The location second row second member, make it with first member at described vault place chimeric and be in first member to the position of vertically staggering; Further locate follow-up member along the structure length direction, and the member in first row and second row is all longitudinally staggered, wherein, these members all are to locate with the equipment that is positioned at longitudinal centre line one side of domes substantially, and having only about half of space below domes at least is freely, is convenient to vehicle pass-through during construction structure.
Therefore, if go up this structure of construction at an existing railway (also may be exactly a road), the obstruction of construction period to traffic can be minimum.And come from the truck that aligns with another row's member to hang member such as if the crane that one and two row's one of members align is set, situation may can not be so just.
In a preferred approach, when align member, crane gear generally is and one of first row or second row's member positioned in alignment, and the space under another row's member is empty, is convenient to pass through.
In another preferred approach, crane gear is positioned outside the circuit of domes, and like this, the almost whole space under the domes all is freely, is convenient to pass through.
Crane gear preferably comprises first and second crane, and such as first and second derrick crane, the method comprises initial that group member that comprises first and second member with described first and second crane gear location.When adopting the method, during second member of location, need not to support first member with a supporter in inside configuration.
Therefore since the present invention in a perithallium of adjacency domes, limits one first back filled region and should distinguish in not compacting of backfill, domes of the present invention can reduce because of the structure natural subsidence makes domes and the possibility in crack occurs. Also in conjunction with the accompanying drawings some preferred embodiment of the present invention is described with way of example below, among the figure:
Fig. 1 is the phantom drawing of domes of Hot work in progress;
Fig. 2 is the plan view at the vault joint of the domes of Hot work in progress;
Fig. 3 is the sectional elevation at the vault joint of Hot work in progress;
Fig. 4 is the sectional view of the vault joint of a completion;
Fig. 5 is the plan view of vault joint before completion, and the top of joint is still exposing;
Fig. 6 is the sectional view of another embodiment of vault joint;
Fig. 7 is by the stereogram of initial two members of the domes of crane hoisting and locating;
Fig. 8 is just at the stereogram of the 3rd member of hoisting and locating;
Fig. 9 is the phantom that is carrying out the domes of hogback backfill;
Figure 10 and Figure 11 are the sectional views of domes after the backfill.
Referring to Fig. 1, domes 1 are made up of first row, 2 and second row's 3 who comprises precast concrete girt strip form member 4.Each row's member all is supported in the longitudinal fluting 5 of base 6.First row, 2 member and second is arranged 3 the member member width that longitudinally staggers half.In first row's 2 end, fill up the room that stays owing to vertically staggering with the member 7 of half width.At the other end of domes, the member (not shown) of another half width is arranged.Fig. 1 has shown a member 4 that is hung second row 3 who puts in place by the suspender 8 that is connected to the crane (not shown).
Two arrange the member intersections in the vault place of domes, and are linked to each other by a vault joint 9, and the details of vault joint 9 is shown in Fig. 2-5.First row 2 and second row, 3 member are identical, and each member all has a pipe fitting that is steel pipe 14 forms, and it is fixed on the middle part at member longitudinal extension edge 11 by two bolts 10.One rubber sheet gasket 60 (such as 3 millimeters thick) is arranged below the head of each bolt 10.During prefabricated units,, be used for admitting bolt 10 at a pair of inlet part 12 of its longitudinal edge embedded set.Longitudinal edge 11 is molded with a groove 13, and it extends the whole length at member edge.Metal sheet roof covering 40, suitably distributes by the pressure that steel pipe 14 transmits guaranteeing admitting steel pipe 14 as the bed course of groove 13.Because relative two rows longitudinally stagger between the members, the steel pipe 14 of each member is with regard to leaning on two members of row relatively and interlock with it, and crosses over the vertical joint 15 between adjacent two members.
Fig. 2 and Fig. 3 have shown the use of the supporting member 16 of angle steel form.Each supporting member 16 usefulness bolt 17 ' is fixed in the upper surface of each member 1, and is used for bearing shearing force before the backfill of the domes back side.Force members relative to two rows to move in opposite directions when having carried out a certain amount of backfill and when holding out against, can shed supporting member 16.In Fig. 2 and construction stage shown in Figure 3, owing to the rolling between the groove 13 of steel pipe 14 and relative member allows relatively rotating of two row's members.
Referring to Fig. 4 and Fig. 5,, just insert the core 50 that does not shrink mortar from the top along the entire longitudinal length of vault joint 9 in case all members finish along the length of domes is in place.Before core 50 is inserted, the inwall and the groove 13 of steel pipe 14 are sloshed, so that the vertical tying means 18 that is formed by core 50 can rotate with respect to member 4 and steel pipe 14 thereof.Like this, in the joint of finishing, can relatively rotate between first row, 2 and second row's 3 the member 4.
In order to insert core 50, be fixed to the bottom that is roughly columniform recess that forms by the groove of facing 13 with for example poly lead-in 51 earlier.Longitudinally be positioned in the cylindrical recess with a pair of reinforcing bar 17 again.The location of reinforcing bar 17 can be realized by for example they being hung with wire.Mortar filling in joint then, and make the tamping of mortar slight vibration with a vibrating head.Mortar occupies the inside of filling up steel pipe 14 and along in the vertical cylindrical recess between the relative member between the adjacent pipe 14 of vault joint length.Be bonded on the core 50 with a waterproof film 19, guaranteeing the watertight of vault joint, the band 20 that a compressible material is made is positioned in the space between the member at joint top, so that joint can slightly cut with scissors commentaries on classics.
Referring to Fig. 6, it has shown another embodiment of vault joint 9, and wherein identical label is used for representing corresponding components.This embodiment difference is that the compressible band 20 in location is pasted on waterproof film 19 on the adjacent top surface of band and member then earlier.In addition, this embodiment comprises the compressible band 21 that is positioned at the joint bottom, and it also makes relative two row's members can cut with scissors commentaries on classics slightly relatively.
Will be noted that the head of each bolt 10 is embedded in the mortar core 50, protrude in steel pipe 14 inner surfaces again, rotate with respect to pipe 14 so can prevent core.The purpose of rubber sheet gasket 60 shown in Figure 4 is for bolt head provides one compressible liner of when rotation is arranged in the vault joint, thereby prevents the stress that core 50 is added.In fact, the rotation of vault joint is minimum, and such as for high 6.2 meters, wide 12 meters domes, the relative displacement between the longitudinal edge 11 of core 50 and member 4 has only 0.2 millimeter.So can not occur any observable torsional cracking in the mortar core 50, even in the embodiment that does not have rubber sheet gasket 60 shown in Figure 6, be like this yet.But if desired, use the circumferential cover cap of making such as plastics, can make bolt head break away from rigid the contact with core 50 by encasing bolt head with the deformable material of one deck such as putty or on bolt head, putting one.
Assembling two row's members 4 are described to form the method for domes 1 below in conjunction with accompanying drawing 7 and 8.Install base 6 exactly, first member 4a is placed in the groove 5 of base.The weight of member is born by base, can make its accurate location with crowbar.At this moment, the top of this member remains in suspended state by the suspender 8 of the first heavy-duty machine 22.Second member 4b be with second crane, 23 location, longitudinal biasing or dislocation equal a member width half (along structure vertically).The top that two cranes side by side make member 4a and 4b is to drawing close together, and contacts with each other sealed.So far, two members are exactly that the oneself supports.Though at this moment two members are in place but still loosely played by crane, so can two members correctly be aimed at being erected at the transit on the structure centre line and aiming at the center of hithermost steel pipe 14.When two members on vault place and base were all correctly aimed at and staggered, two cranes all can be decontroled the member of its lifting, after this, only needed a crane locate subsequent members.Fig. 8 has shown the location of the 3rd member 4c, and this moment, first member 4a was to be in the state of self supporting as second member 4b.
Yet the most handy crane is held in place and supports a member (first member 4a or second member 4b), and hangs the 3rd member also to hold up in an identical manner and align with another crane; Place the 4th member and alignment then, also will lay the arch bar 7 (referring to Fig. 1) of half width.In case the member of four full-scale members and half width location finishes, second crane can have been decontroled with regard to no longer needing.
Each adjacent member in the same row was held together with wire before placing follow-up member, such as adopting the identical built-in fitting of built-in fitting that is used for connecting suspender 8.Will be noted that, can finish all working that the member assembling is connected with vault from structural outer, like this if this domes will be built in road or railway top, traffic in work progress below the structure can continue to keep the domes for straight, it is long that the speed of laying prefabricated units 4 is approximately 30 meters of every days, and for curved structure, it is long to be about 25 meters of every days.
The hogback backfill of domes is described referring now to accompanying drawing 9 to 11.Around the domes four different back filled regions are arranged, it is determined by the compacting situation.The A area definition is a perithallium that contacts with structure.This district's horizontal width " a " at the pier place is 0.40 meter, and in this district, backfilling material answers loosely to place and not compacting, so that do not make arcual component 4 that unwanted moving taken place.
In abutting connection with the B district in A district at the horizontal width " b at pier place
1" be 1.60 meters, reduce to 1.0 meters vertical thickness " b to the domes top
2".Backfilling material in this district can come compacting with light-duty walking driving compacting equipment 30.Should monitor number of times that compacting equipment pressed to avoid undue compacting, produce uneven load on the structure because undue compacting meeting makes member produce displacement or makes.The weight of compacting equipment 30 generally should be no more than 1500 kilograms.In case the backfill thickness on the structure top surpasses " b
2", then just can on the structure top, adopt heavier compacting equipment 31.From Fig. 9 as seen, outside lower is used equipment 31 during each stage in along continuous straight runs backfill B district.The C area definition is a rectangular area, and its two edges to the horizontal range " C " of domes footing is 2 meters.The C district extends upwardly to last backfill height, and in this specific embodiment, this height " X " is 1 meter of arch over top.In the C district, can use heavier compacting equipment 31, but not apply vibration.Equipment 31 can be only in the internal vibration of D district, and the D district is outside the vertical boundary in C district.
Consider the type of backfilling material, show area E with hacures among Figure 10.The thickness " e " that (the B district that therefore comprises A district and 0.6 meter) measured from the arch outward radial in this zone is 1 meter.In the E zone, the maximum particle size of material is 150 millimeters, and the percentage of 0.080 millimeter particulate is less than 15%.
In all each stages of backfill, note guaranteeing both sides with essentially identical speed backfill domes.Backfill difference in height in both sides should be no more than 0.5 meter, to avoid on single member 4 or the total 1 undue eccentric load being arranged.
