Fig. 2 is the front schematic view of lifting gear.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Figures 1 and 2, steel boxed cofferdam integral elevating equipment, including lifting gear, hoisting platform, platform for lining with
And steel boxed cofferdam ontology；Steel boxed cofferdam ontology is located on platform for lining, and hoisting platform is located at platform for lining both sides, lifting dress
It sets to be evenly distributed and be fixed on hoisting platform；The lifting gear includes a L bracket 1, and frame bottom is pedestal 2, after pedestal
Side is equipped with hoist engine 3, and pedestal front end is equipped with two steel pipe posts 4, is connected by crossbeam 5 at the top of steel pipe post, steel pipe post top
It is also connected by tie-beam 6 between end and pedestal rear；Pedestal front end is equipped with a fixed pulley 7, and crossbeam center is equipped with fixed pulley group
8, fixed pulley group lower section is equipped with running block 9, and the steel wire rope 10 of hoist engine is protruded horizontally up from hoist engine, passes through pedestal front end
Fixed pulley is upwards about being located on fixed pulley group and running block；Running block bottom is equipped with suspension hook 11.
Your it is applied at present in this equipment in the remaining construction for believing Bridge Main Pier cushion cap of Yingtan, steel boxed cofferdam ontology is single wall
Without bottom structure, the box structure being mainly made of side plate and inner support, effect is blocked water temporarily together with bottom concrete,
Anhydrous dry construction condition is provided for cushion cap and pier construction.Since casing size is larger, for convenience of constructing, steel jacket box, which uses, to be divided
Block makes, on-site consolidation, and hoist engine promotes the thinking of decentralization.
Main pier (11#, 12#) cofferdam height 14.5m, points three restrainings are made, from bottom to top the high 2.5m of first segment successively, the second section
High 6.0m, the high 6.0m of third section.It tears open and transports for convenience of peace, side plate is mainly the calibrated bolck of width 3.0m, remaining is adjusting block,
Connecting flange is done using 180 × 110 × 12 angle steel of ∠ between block and block, 2 holes row spacing 20cm φ 20mm are set on flange, by plum blossom
Shape arranges that φ 18mm are bolted.
Single steel jacket box weight is 360t.
(1) side plate
Side plate uses single-wall structure, is made of siding and ribbed stiffener.The section of siding first and third is using 6mm steel plates, second section
Using 8mm panels, ribbed stiffener is using [[18 channel steels erect rib, erect rib spacing 60cm, cross rib spacing 40cm for 10 channel steel cross ribs, Two bors d's oeuveres 2.
Cofferdam siding surrounding sets 180 × 110 × 12 angle steel flanges of ∠.
(2) steel jacket box inner support
Set 5 inner supports on the inside of cofferdam, first of inner support is located at away from the base opening 5.7m height of cofferdam, then upward inner support
Spacing is successively：2.3m、2.3m、2.5m、1.5m.2 are all made of at support, and [25a makees outer waistband, and with 2, [30b makees interior waistband；Cofferdam
First and second layer of lateral inner bracing piece uses φ 820mm × 8mm steel pipes, third and fourth, five layers use φ 630mm × 8mm steel pipes, steel
Pipe end sets 2 [25a diagonal braces；First and second layer of cofferdam vertical supporting bar uses φ 630mm × 8mm steel pipes, third and fourth, five layers adopt
With φ 402mm × 6mm steel pipes；Cofferdam transverse ends are supported using shape steel bracket, and it is 2I45b, diagonal brace 2 that holder, which directly supports,
[25a.2 [18 channel steel power transmissions of φ 820mm steel pipes outsourcing are used at longitudinal and transverse inner support lateral.
Steel cofferdam is in assembly, using drilling platform transformation as the platform for lining in cofferdam.Steel jacket box assembly utilizes periphery
Steel pile casting steel corbel supports, and is unified in a plane according to casing size using shaped steel and carries out piecemeal assembly, first segment is assembled
Steel corbel support platform is removed by 10 hoist engine Synchronous liftings to be transferred to the water surface, then carry out the spelling of two, three segments after the completion
Dress and sinking.
Cofferdam, which is saved, to be bolted between section using φ 18, and bolt hole uses the quincunx spacing 20cm of 2 rows, and seam is using double
The ripe glue of face glue+18mm (width) × 4mm (thickness) is clogged, it is ensured that seam is waterproof.
When transferring cofferdam, since hanging device limits in water, hoisting platform is set up using steel jacket box periphery and places 10
The double group Synchronous lifting decentralizations of 10 ton of 6 pulley blocks, pulley blocks select 80 ton of 6 wheel pulley blocks, by 22 import steel wire ropes of theoretical calculation φ
Every crane capacity of bidirectional slide wheel group reaches 80t, and 80t × 10=800t ﹥ 360t can meet lifting requirements.Hoist engine rotating speed 22m/
Min, 22 ÷ 12=1.83m/min of lowering velocity.
Since this steel jacket box is single-wall structure, inside dimension is larger, to ensure uniformly to sink in sinking watching, ensures flat
Face height difference is no more than 20cm.
Since casing is bulky, certain guider is must be provided in sinking, steel shield is corresponded on the siding of cofferdam
8 bearing arrangements are arranged in the position of cylinder, resist steel pile casting, prevent decentralization hour offset, ensure after sinking in place, meet setting for cushion cap
Count size.
Remaining your bottomless steel boxed cofferdam of Bridge Main Pier single wall of letter, structure construction is easy to process, spells and tears open conveniently, can repeatedly have enough to meet the need
It uses, subsidence process is simple, saves the time, achieves remarkable effect.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
