Summary of the invention:
The object of this invention is to provide the application of a kind of hydraulic pressure sedimenting system in Platform Deck reforming technology, adopt cutting column, according to triangle stability characteristic (quality), matrix distribution mode every a top one installs hydraulic jack, the unified technology mode falling to installing of final Platform Deck entirety, effectively overcomes or avoids the shortcoming that exists in above-mentioned prior art or deficiency.
The application of hydraulic pressure sedimenting system of the present invention in Platform Deck reforming technology, comprises cutting support post and cutting antiskid column, installs hydraulic jack.Described cutting support column and antiskid column, 15 support posts and 6 antiskid columns that hydraulic jack need be installed, 0.9-1.0 rice is up sliced off from mat case, support column and the antiskid column cutting 0.45-0.55 rice of hydraulic jack will be installed, upper deck entire lowering is welded and fixed again to the At The Height of upper deck back gauge baseline 4.5m; Described installation hydraulic jack, be first all pipings of the support post of upper deck and antiskid column top are cut off, then utilize triangle stability characteristic (quality), take to intersect in length and breadth, matrix distribution mode every a top one installs hydraulic jack, and hydraulic jack controlled by switch board.
Wherein, described installation hydraulic jack is provided with pallet, hydraulic jack and reinforcement support in turn in the support post after cutting.Described installation hydraulic jack, be provided with hanging basket in the antiskid column after cutting, be provided with pad and hydraulic jack in turn in hanging basket, hanging basket is provided with clips outside top.Described pallet top is channel-section steel, the bottom of cross welding is round table-like welded unit.After described 21 hydraulic jack install, operation hydraulic jack, safety switches the cutting of each support column steadily.By remaining 15 support posts and antiskid column, up slice off 0.45-0.55 rice, then operate hydraulic jack from mat box top, slowly transfer and fall on mat case to support column, it is firm again to be welded.Construct according to this step successively, at the bottom of upper deck, withdraw from hydraulic jack during distance 2.4 meters, mat box top, to the support column after the every root cutting declined, correspond on original position and carry out full weld, the entirety completing upper deck falls.
The present invention compared with prior art tool has the following advantages:
1, reasonable in design, easy to operate, reliable and secure.
2, cost is low, good economy performance.
3, less by sea situation meteorological effect.
4, for the deck-landing convenient construction that span is larger.

Detailed description of the invention
Consult Fig. 1-Fig. 6, the application of a kind of hydraulic pressure sedimenting system in Platform Deck reforming technology, comprise cutting support post 3 and cutting antiskid column 4, hydraulic jack is installed.Cutting support column 3 and antiskid column 4, by laterally 4 rows of support platform upper deck 1 overall weight, longitudinally 9 rows totally 36 root posts, 15 support posts 3 and 6 antiskid columns 4 of hydraulic jack 7 need be installed, 0.9-1.0 rice is up sliced off from mat case 2, the support post 3 and antiskid column 4 of not installing hydraulic jack 7 are cut 0.45-0.55 rice, upper deck 1 entire lowering is welded and fixed again to the At The Height of upper deck 1 back gauge baseline 4.5m; Hydraulic jack 7 is installed, be first all pipings of the support post 3 of upper deck 1 and antiskid column 4 top are cut off, then utilize triangle stability characteristic (quality), take to intersect in length and breadth, matrix distribution mode every a top one installs hydraulic jack 7, and hydraulic jack 7 controlled by switch board 5.
Installing hydraulic jack 7, is be provided with pallet 8 hydraulic jack 7 in the support post 3 after cutting in turn and strengthen support 6.Install hydraulic jack 7, be provided with hanging basket 10 in the antiskid column 4 after cutting, be provided with pad 11 and hydraulic jack 7 in hanging basket 10 in turn, hanging basket 10 is provided with clips 9 outside top.Pallet 8 top is channel-section steel, the bottom of cross welding is round table-like welded unit.After 21 hydraulic jack 7 install, operation hydraulic jack 7, safety switches the cutting of each support column steadily, by remaining 15 support columns 3 and antiskid column 4, up slices off 0.45-0.55 rice from mat case 2 top.Then operate hydraulic jack, slowly transfer and fall on mat case 2 to support post 3 and antiskid column 4, it is firm again to be welded.Construct according to this step successively, at the bottom of upper deck during distance 2.4 meters, mat box top, the support post 3 on hydraulic jack 7 top hangs up properly jack, and other end hangs up properly jack, hydraulic jack 7 is pulled out and transports on the bank.To the support post 3 after the every root cutting declined and antiskid column 4, correspond on original position and carry out full weld, the entirety completing upper deck 1 falls.
In operation, hanging basket plays support hydraulic jack 7.As shown in Figure 2, a support post at its center is provided with two hydraulic jack 7 for 3 times, to strengthen its holding power and balance.Hydraulic jack 7 reaches control cabinet 5 on the bank by withstand voltage manifold, carries out unifying lock control, and unification is transferred, and unification is closed down.By operating personnel's operating control handle, slowly transfer hydraulic jack 7 to support post 3 and antiskid column 4 fall mat case 2 welds firm.
