Abstract
The invention discloses a joining method of a dock gate. The method is characterized by sequentially comprising the following steps: (1) dividing the dock gate into a plurality of subsections which are manufactured respectively, and respectively hoisting the plurality of the subsections to corresponding positions by utilizing a floating crane; (2) correspondingly moving the plurality of the subsections to an iron pier at a certain height from the ground by utilizing pulley trolleys; (3) welding, polishing and coating the subsections; (4) closely pasting two ends of the dock gate with sealing rubber strips, then jacking up the dock gate by a plurality of jacks, and tensioning inwards the dock gate by the pulley trolleys and a pipe roller so that the dock gate is attached to a dock entrance; and (5) fully jacking up the dock gate by the plurality of the jacks, removing the iron pier, and finally laying down the dock gate. In the method, the pulley trolleys and the floating crane are adopted according to a pulley principle, which saves manpower and material resources; and the method has the advantage of good sealing effect, and is simple in operation and convenient in construction.
Description
Technical field
The present invention relates to a kind of folding method of dock dock gate, especially before the explosion of dock cofferdam, guarantee the use of dock gate integraty.
Background technology
Because the dock gate length overall 47x8x13.5 rice of dock, about 800 tons of total weight, volume too greatly, too heavy, now mainly rely on the harbour crane barge to lift, but crane barge itself to turn angle limited, and dock gate mouth place is less, it turns difficulty greatly, be difficult to appointed positions is hung in the segmentation of dock gate, and the factor of some geographical environments, lifting more is difficult to put in place; And expend great amount of manpower and material resources.
Summary of the invention
Technical matters to be solved by this invention provides a kind of folding method of dock dock gate, and it utilizes the pulley principle, has saved human and material resources, avoids using large-scale gauntry crane equipment.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of folding method of dock dock gate is characterized in that: steps in sequence is:
1) the dock dock gate is divided into a plurality of segmentations, makes respectively, a plurality of segmentations are hung corresponding position with crane barge respectively;
2) adopt the pulley dolly accordingly a plurality of segmentations to be moved on the iron pier of liftoff certain altitude;
3) then to segmentation weld, polishing, application;
4) be adjacent to the dock gate two ends with sealing rubber strip, use many jacks then, inwardly strain dock gate with pulley dolly and pipe roller and touch the dock gate doorway dock gate jack-up;
5) use many jacks with the complete jack-up of dock gate again, move the iron pier, at last dock gate is put down.
As preferably, described dock gate is divided into four segmentations.
As improvement, described jack is the rectangular distribution setting in the dock gate front and back.
At last, the liftoff height of described iron pier is designed to 80～100cm.
Compared with prior art, the invention has the advantages that: utilized the principle of pulley, adopted pulley dolly and crane barge, saved human and material resources, avoid using large-scale gauntry crane equipment, and sealing effectiveness has been good; Simple to operate, easy construction.
Description of drawings
Fig. 1 is a dock dock gate scheme drawing of the present invention;
Fig. 2 closes up the process scheme drawing for the dock dock gate.
The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Shown in Fig. 1-2: a kind of folding method of dock dock gate, its dock gate 1 length overall 47x8x13.5 rice, about 800 tons of total weight, it is 2 section 1.2 that dock gate is divided into 70T, 280T is 2 section 1.1, amounts to 4 segmentation manufacturings; Four segmentations are hung corresponding position with crane barge respectively and since crane barge itself to turn angle limited, and the dock entrance place is less, it turns difficulty greatly, 4 segmentations can't be hung assigned address; Utilize the pulley principle, adopt four segmentations of four pulley dollies, 2 usefulness steel ropes, 3 tractions, accordingly four segmentations are moved to assigned address, welding for convenience, polishing, painting work are placed four segmentations on the iron pier of liftoff 90cm; Weld then, polishing, application, with four segment foldings, dock gate 1 is carried out tightness test; Because dock gate has the distance of 60cm from dock entrance, is close to the dock gate two ends with sealing rubber strip, then with jack with dock gate jack-up, inwardly strain dock gates 1 with pulley dolly 2 and pipe roller 4 and touch dock dock gate mouth; Be arranged in the front and back of dock gate again with the jack of 16 100T respectively equably,, move objects such as iron pier, at last dock gate 1 is put down dock gate jack-up; Because soft by Haiti base, difficulty is bigger, the whereabouts amplitude is 5cm, uses close implementations good at present; Adopt pulley dolly and crane barge, saved human and material resources, simple to operate, easy construction.
Claims (4)
