Description
Technical field
The present invention relates to it is a kind of can adjust automatically bottom elevation bridge incremental launching construction equipment, belong to bridge Construction Technology neck
Domain.
Background technology
The traffic form that science of bridge building is wanted as Modern Heavy, the implementation of science of bridge building, which has to pass through, accurately to be calculated and sets
Meter, the requirement in construction to technology are also high.Incremental launching construction method is because with safe, strong operability and at low cost etc.
Advantage becomes the fundamental technology of science of bridge building in recent years, especially in the bridge and continuous bridge of prestressed reinforced concrete construction type
Extensive use in the construction of beam.
Bridge incremental launching construction is along bridge y direction, precasting yard is set to pour beam section after abutment, after reaching design strength,
Apply prestressing force, pushing tow, vacates pedestal and continue to pour beam section forward, is coupled with after-applied prestressing force with first one section of beam, until will
Entire bridge beam section pours and pushing tow finishes, and finally carries out system transform and forms bridge.
Incremental launching construction mode common at present mainly has two kinds of pull-alongs (towed) and walking.Either walking top
Construction or pull-alongs incremental launching construction are pushed away, in order to eliminate dead load and often amount of deflection caused by the long-term effect of effect mobile load, is led to
It often needing to reserve the correcting value opposite with direction of displacement in construction or making, this correcting value is known as camber, and on bridge top
It pushes away in work progress, due to the presence of camber, Temporary Piers are constantly changing relative to the bearing height at beam bottom, can cause certain
Temporary Piers seat empty and the phenomenon that excessive other Temporary Piers bearing support reactions, and then influence the safety of Temporary Piers and the office of beam
Portion's stability, it is therefore desirable to adjust the bottom elevation of Temporary Piers pier top in time during the pushing tow of bridge.
At present during bridge incremental launching construction, beam bottom mark is typically adjusted by the way of manually increase and decrease billet
Height, this mode is not only cumbersome, waste of manpower, Adjustment precision is low, speed is slower, and a fixing is caused to speed of application
Ring, and billet due to specification it is different, be difficult to realize it is reusable.In addition, either walking incremental launching construction still drags
Pull-type incremental launching construction, is required for adjustment bottom elevation in work progress, but since the two form of construction work is there are apparent difference,
Therefore previous walking incremental launching construction and pull-alongs incremental launching construction are all the respective bottom elevations of each self-adjusting, in addition, walking
With the difference of pull-alongs, also result in current bottom elevation adjusting apparatus and be only applicable to walking incremental launching construction or pull-alongs pushing tow
Construction, it is impossible to the two dual-purpose, restricted application.

It is of the present invention can adjust automatically bottom elevation bridge incremental launching construction equipment use when：
First after the Temporary Piers of bridge 1 are provided with, jack 7 is determined according to the maximum support reaction during pushing tow
The number of jack 7 between tonnage and upper beam 4, central sill 5 and underbeam 6, according to bottom elevation variation during pushing tow and in fact
Border situation determines the size of upper beam 4, central sill 5 and underbeam 6；Then as shown in figure 4, automatic adjustment equipment is installed on Temporary Piers 1
Between beam body 2 (upper beam 4 is set on the bottom of beam body 2, and underbeam 6 is set on the top of Temporary Piers 1)；
After the completion of equipment assembling, according to different push construction method, different height regulation methods is taken, specifically such as
Under：
During walking incremental launching construction, thrustor 3 is walking type pushing device, which carries pushing tow thousand
(including jack and level jack), the jack for walking type pushing device being controlled to carry first is risen on jin top
Drop, if jack reaches range, the top surface of the sliding babinet 32 of thrustor 3 can't effectively contact beam body 2
Bottom, adjustment jack 7 positioned at central sill 5 and underbeam 6 between rises at this time, until slide box top effective contact beams bottom,
The jack 7 between upper beam 4 and central sill 5 is controlled to lift to required bottom elevation, the exact numerical values recited of the control lifting of measurement ruler 8 again,
It is achieved thereby that the adjustment of the bottom elevation to walking incremental launching construction；
During pull-alongs (towed) incremental launching construction, thrustor 3 is identical with walking incremental launching construction, is also walking pushing tow
Device, the walking type pushing device carry pushing tow jack (including jack and level jack), control stride first
The jack that formula thrustor carries is lifted, while the jack 7 between upper beam 4 and central sill 5 is controlled to lift, and is made
It needed for be unable to reach during bottom elevation, then controls in sustained height the top surface of the top surface of beam 4 and the sliding babinet of thrustor 3
It sets up the jack 7 between central sill 5 and underbeam 6 to lift, the exact numerical values recited of the control lifting of measurement ruler 8, it is achieved thereby that pull-alongs
The adjustment of the bottom elevation of incremental launching construction.
In conclusion the bridge incremental launching construction equipment of the present invention, can be suitable for walking incremental launching construction and pull-alongs simultaneously
The bottom elevation adjust automatically of (towed) incremental launching construction, and accuracy height is adjusted, mechanization is adjusted, regulates the speed
Soon, manpower is saved, ensure that the safety and stability of bridge, relative to the prior art, there is conspicuousness progress, have and promote
Application value.
It is last it is necessarily pointed out that：The foregoing is merely the preferable specific embodiment of the present invention, but the present invention
Protection domain be not limited thereto, any one skilled in the art in the technical scope disclosed by the present invention,
The change or replacement that can be readily occurred in, should be covered by the protection scope of the present invention.
