Description of the drawings
It is further illustrated the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is the floor map for automating case field and conventional case field；
Fig. 2 is conventional case field diagrammatic cross-section；
Fig. 3 is automation case field diagrammatic cross-section；
Fig. 4 is the level schematic diagram that construction channel is formed in this example.
Specific implementation mode
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is further explained.
This part illustrates the implementation process of this programme by taking certain harbor automatic stockyard as an example.
It is long and narrow layout that automatic yard design in this example, which uses ARMG track crane operating types, each case area,.Its
On design scheme with conventional container stockyard difference lies in：
1) setting collection card channel, stockyard are used as truck transport container channel, construction period during runing in conventional case area
It can also be used as construction channel and transport the construction materials such as three slags, concrete.And case field is automated using unattended, realization case field nothing
Peopleization manages, therefore no longer sets collection card channel, can not be using collection card channel as the construction channel of three slags, concrete, such as Fig. 1 institutes
Show.
2) conventional case field uses tire crane operation, only need to arrange tyre crane concrete track in case field both sides.And this example
In automatic yard design scheme, unmanned automation case field uses ARMG track crane operations, case field both sides to arrange Novel U-shaped track
Slot (as shown in Figure 2).Construction channel is can be used as from the floor plan design as it can be seen that repair track between only two track grooves,
Right maintenance channel only has 3.9m wide, and construction machinery, vehicle must can enter case field across track crane basis, carry out three slags
Equal raw materials paving and being compacted.This method will certainly cause the damage for being completed track U-type groove concrete wall.
3) conventional case field because case sector width it is limited, case is not provided with gutter in field；And it automates among each case area in case field
Open drain is set, cause three slag of case base can not be formed it is elongated pave, influence three slag spreading qualities, and construction efficiency is low.
4) in this example fractional orbital basis across hydraulic fill sand, jackstone back filled region and area of cutting into a mountain, different geological conditions and
Differential settlement caused by track infrastructure segmentation dead weight is different will lead to the absolute altitude problem of later stage track installation.
In this way, the automatic yard in this example is when carrying out case field foundation construction, charging car and road roller then need to be from dimensions
Repair into cartonning field, certainly will will be across track foundation and track groove, and in work progress, track groove is first constructed, and from
Dynamicization stockyard track cell wall absolute altitude is above the ground level absolute altitude, this will lead to the breakage of work progress middle orbit cell wall.Similarly, it drains
Bright ditch has blocked the continuous construction of case field, influence basis pave and consolidation effect.
According in this case, this example according to automatic yard layout characteristics, the change working procedure of innovation, by track groove and
Open drain is constructed in two times, that is, carries out secondary connecing high construction：It constructs for the first time, reduces the height of track cell wall and furrow bank, the
Secondary construction is poured again to designed elevation.
Principle accordingly, the secondary basic process for connecing high construction here are as follows：
First, it carries out track groove and open drain is constructed for the first time, and construction elevation of track groove and maintenance channel are mixed
Solidifying soil padding designed elevation is consistent, and open drain absolute altitude is consistent with the basic three slag bed course top surface absolute altitudes in case angle；
When the step is constructed, track groove and the positioning of open drain baseline are first carried out, foundation trench excavation, Zhi Limo are then carried out
Plate, reinforcing bar binding, finally carry out track groove and open drain concreting；
Then repair channel concrete cushion pour with track groove railway ballast roll compacting construction；To avoid railway ballast from compressing
It may be rolled damaged problem, a little higher than track groove Sidewall Height of track groove railway ballast packed height with track groove sidewall；
Then, case area's construction is carried out；
When case area constructs, repair track concrete cushion between the adjacent areas Liang Xiang is poured first, is returned after the completion of bed course maintenance
Railway ballast stone is filled out to track groove, railway ballast backfills absolute altitude to having poured bed course, is rolled railway ballast to closely knit after the completion of backfill, until
This, forms construction channel；
Then it carries out three slag of case area to pave and be compacted, when construction first covers open drain with customization steel plate, prevents road roller
Damage open drain side wall by pressure；After three slags are compacted and reach designed elevation and intensity, carries out case angle base concrete and pour, at this time
Using maintenance channel and the track groove basis for filling in railway ballast collectively as construction channel；
It then carries out filling out three slags of shelves between paving case angle basis, pour and fill out a grade facing concrete；
Finally, track groove is carried out on the basis of the track groove formed in first time construction and open drain connects high second
Construction, and to absolute altitude.
Track groove and open drain is secondary when connecing high construction, first carries out track groove and the cleaning of open drain side wall top surface, really
Protect free from admixture and dust；It then carries out connecing high-order bit reinforcing bar binding and welding, it is ensured that connect high-order bit reinforcing bar and once construct with lower part
Position reinforcing bar forms entirety, and ensures the ratio of reinforcement；Template is finally carried out to set up and concreting.
This example is connect high arrangement and method for construction and can be formed efficient construction channel using secondary, meets earthwork balance, three slags booth
Paving and case angle basis, the crossed construction for filling out shelves, lifting construction efficiency.Meanwhile to ensure the construction quality, this example is also reinforced pair
The compacting measure of the dirt road base, three slags of case field.On the other hand, this example is also according to construction time track foundation, case angle basis, synthesis
The important features such as pipe trench position is in different geological conditions, settling amount and Subsidence trend, by reserved heavy to pre-embedded bolt
Drop, cell wall is secondary connects high working measure, enhances flexibility and the adaptability of construction.
Carrying out the secondary Specific construction process for connecing high construction in this example as a result, is：
1) first time construction, track U-type groove and row are carried out to 4 track U-type grooves in construction cell and open drain first
Water bright ditch spread working hour reserves 15cm and 45cm respectively.
In this step when once constructing to track groove, keep its absolute altitude consistent with maintenance channel concrete cushion absolute altitude, i.e.,
Reserved 15cm, it is secondary to pour when connecing high；Simultaneously in order to which subsequent construction can make vehicle smoothly cross over track groove, track groove in the process
Wall reinforcing bar can not be inserted into former design position, and reinforcing bar is inserted at an a little higher than construction elevation by this example.
In this step when once constructing to open drain, keep its absolute altitude consistent with three slag bedding design absolute altitude of case area, i.e.,
Reserved 45cm, it is secondary to pour when connecing high；Simultaneously in order to which vehicle can be made smoothly to cross over open drain during subsequent construction, drain
Bright ditch reinforcing bar can not also be inserted into former design position, and open drain vertical reinforcement is inserted into a little higher than primary construction in this example
At absolute altitude, the steel plate of customization is used in combination to carry out open drain bedding.
2) it pours and repairs track concrete cushion between the adjacent areas Liang Xiang, backfill railway ballast stone is to track after the completion of bed course maintenance
U-type groove, railway ballast backfill absolute altitude to having poured bed course, after the completion of backfill using exciting force >=400kN vibrated rollers to railway ballast into
Row rolls, it is ensured that railway ballast is closely knit.
In the working procedure of the step so that railway ballast absolute altitude and repair track are mixed in track cell wall absolute altitude, track groove
Solidifying soil padding absolute altitude is consistent, to may make Construction traffic that can walk in track groove, and unlikely destruction track cell wall, to make
Maintenance channel both sides track groove can also be used as driving channel, the thus broadening walking width (as shown in Figure 4) of Construction traffic.
3) three slag bed courses in case area are carried out to pave and roller compaction construction, once constructing because of open drain reduces furrow bank absolute altitude,
After open drain reduces 45cm constructions, it is identical as the basic three slag top surface absolute altitudes in case angle that bright ditch pours top surface absolute altitude for the first time, thus
Can guarantee that three slags are when paving and rolling in case area, construction machinery can directly across open drain, and it is unlikely damage open drain by pressure, together
When three slag bed courses near open drain can be also compacted, avoid the phenomenon of heavily loaded base corner compactness deficiency from occurring, improve
The construction quality of engineering key structures.
4) three slag curing periods it is up to standard after can pour case angle base concrete.
5) three slags of shelves are filled out between the basis of paving box angle after the basis form removal of case angle, pours and fills out a grade facing concrete.
6) it carries out track groove and the secondary of open drain connects height.Track groove and open drain is secondary when connecing high construction, it is advanced
Row track groove and the cleaning of open drain side wall top surface, it is ensured that free from admixture and dust；It then carries out connecing high-order bit reinforcing bar binding and weldering
It connects, it is ensured that connect high-order bit reinforcing bar and form entirety with the construction part reinforcing bar of lower part one time, and ensure the ratio of reinforcement；Template is finally carried out to take
And if concreting.
7) carry out track groove railway ballast pave, sleeper and track installation process, ultimately form ARMG crane operation casees area.
The secondary ARMG crane operation casees area for connecing high arrangement and method for construction and being formed, gantry crane load are transmitted by rail accordingly
Lower part railway ballast is passed to sleeper, then by sleeper；Since sleeper bottom absolute altitude will be less than the overlap joint absolute altitudes of track groove one or two times, and cell wall
Actually free end, therefore the secondary part that pours is by notable load action, it is secondary pour track groove will not be caused completely quality and
Appearance effects.
Furthermore since the place scale of automatic yard is bigger, construction period is long, if disposably that track groove is complete
Portion's construction is completed, and in entire work progress middle orbit slot there will be big problem is settled, certainly will influence completion of works quality even
Influence normal operation；In this example high construction technology, track groove construction for the first time to second are connect using secondary for track groove
Secondary construction gap periods are up to 2 years as long as, can be applied for the second time for due to track groove sedimentation caused by uneven settlement of foundation
Working hour completion makes up, and effectively ensures the operation of entire construction quality and later stage engineering.
