Description
Technical field
The present invention relates to a kind of construction techniques, specifically a kind of narrow regional combined type dragging suspension basket merogenesis installation side
Method.
Background technique
Combined type dragging suspension basket is to be cared in Hanging Basket stringer front end using the suspension cable of segment to be poured to form front fulcrum,
Hanging Basket rear end is anchored at and has been poured on beam section bottom plate, since bridge need to set for single cable plane architecture front end mould to stability is poor
It sets central bearing point to be balanced, load is transmitted to by girder and king-tower using the mode of transfer force that hanging and guy rope combine respectively, is used for
Beam face, wing plate be wider and section is approximately the single cable plane cantilever prestressed concrete cable-stayed bridge of up-side down triangle, bears beam body self weight
And construction loads and the large scale equipment that can continuously push ahead construction.This Hanging Basket is that comprehensive central bearing point Hanging Basket and dragging suspension basket are applied
Work process characteristic and formed, it is more heavier than common Hanging Basket and in large scale.Its mounting means, which just seems, to be even more important, conventional to install
There are mainly two types of engineering methods, the first, it sets up temporary construction platform and large-scale lifting appliance assemble in situ combined type guy rope is recycled to hang
Basket engineering method；Second of utilization lifting appliance first installs temporary continuation tackling system on beam face, then immediately below predetermined position
Bottom basket system is completed in face, and entire bottom basket is promoted to predetermined altitude using the tackling system of installation and is installed in place.But in recent years
To build investment with national basis and increase, bridge need to be built in many places deep in the mountains, encounter that bridge height is larger and place is narrow
Small area is constructed according to above-mentioned engineering method, and not only cost is big, and some also needs progress massif excavation that can just vacate place, security risk
Greatly actually unwise act, therefore, it is necessary to a kind of actual installation methods in more fitting scene, and can not destory the scene natural environment
Natural hybridized orbit is reduced, safety, completion installation task quickly, economic are reached.
Summary of the invention
It is above-mentioned to solve the purpose of the present invention is to provide a kind of narrow regional combined type dragging suspension basket merogenesis installation method
The problem of being proposed in background technique.
To achieve the above object, the invention provides the following technical scheme:
A kind of narrow regional combined type dragging suspension basket merogenesis installation method, includes the following steps；
Step 1: using distribution beam plank and dragging track is completed on 0# block bracket, one Pin frontal arc head of tower crane installation is utilized
Step 2: forming entirety using main longitudinal grider after tower crane installation lateral ties and the 2nd Pin makes ballast completely on bracket；
Step 3: slowly Hanging Basket is migrated in place along track using 5t cucurbit；
Step 4: it migrates and triangle main couple above arc first section is installed afterwards in place and slings main longitudinal grider, after so that bracket is reduced stress
2nd Pin segmental arc is installed；
Step 5: inside main couple is all installed and lifts main longitudinal grider；
Step 6: installation carrying platform truss and outer triangle main couple；
Step 7: various operation platforms, slide plate, template etc. are installed；
Step 8: tension structure, thrust structure are installed after to the construction of 1# block；
Step 9: removing main couple lateral ties inside and outside top, main couple walking 3.6m in top, outer main couple walking 3.4m,
After all walkings in place, lateral ties are installed again；
Step 10: it is laid with track, pulley is installed under girder, when main longitudinal grider skids off about 20cm, by intermediate bracket anchoring temporarily
In 1# block bottom plate；
Step 11: the connection steel band between installation piston shoes and carrying platform；
Step 12: walking about 2m or so will can walk on after the anchoring in place of second bracket until in place；
Step 13: spreading main longitudinal grider II and first time sliding rail are installed into walking section anchoring again；
Step 14: first time sliding rail root preformed hole is buried in construction 1# block segment, by the mobile 2.6m of bottom sliding rail, then spells
Subsequent main longitudinal grider III and second of sliding rail are filled, good after installation to move 3.4m again, so far Hanging Basket is whole all installs, and carries out
The construction of 2# block section standard paragraphs.
As a further solution of the present invention: lifting by crane in the step 4 on mounting rail and it is anchored simultaneously after triangle main couple
The jack up units such as lifting jack are installed.
As further scheme of the invention: distribution beam is securely welded with bracket in the step 1, distribution beam bottom
Add lateral diagonal brace.
Compared with prior art, the beneficial effects of the present invention are: this method efficiently solves and field larger in bridge height
The bottom basket in the narrow area in ground is promoted to predetermined altitude and installs installation lifting problem in place, and being not required to excavation massif can lift by crane,
Construction cost is greatly reduced, safety reliability is high, while not destroying local natural environment, reduces natural hybridized orbit.
