Abstract
The invention discloses a wharf transportation and loading/unloading process for a slender structure. The process comprises the following steps: I, placing a barge and the slender structure properly; II, arranging two groups of jacking slippage devices at the bottom of the slender structure, and arranging the other two groups on the barge; III, arranging H-shaped steel on the barge; IV, placing the two groups of jacking slippage devices at a higher position, jacking the slender structure, transporting the slender structure to the front edge of a wharf, and stopping advancing; V, performing a first weight transfer process on the slender structure; VI, continually transporting a jacking slippage device onto the barge for the slender structure, and stopping advancing; VII and VIII, performing a second weight transfer process on the slender structure; transporting the slender structure to a proper position on the barge; IX, dropping the slender structure on the H-shaped steel for fixing, and ending shipping. By adopting the wharf transportation and loading/unloading process, the influence on the loading and unloading transportation operation of the slender structure due to insufficient carrying force is avoided, and the problem of the dependence of the conventional marine engineering structures on floatation hoisting and ship unloading is solved.
Description
Technical field
The present invention relates to the quay transportation of works, handling technology, particularly relate to a kind of quay transportation, handling technology of slender structure thing.Belong to Offshore Engineering field.
Background technology
At present, in ocean engineering, the quay transportation for slender structure thing mainly adopts crane barge, and is characterized in: lower to the requirement of harbour and barge, uses more convenient, but costly, and the impact by crane barge sailing date is very large.And generally adopt crane barge lifting or multiple stage crawler crane to combine the method for lifting in shipment exit for the loading, unloading ship of slender structure thing.But due to the restriction by crawler crane Lifting Capacity, the module that weight is greater than 500 tons all can only adopt crane barge to complete its loading, unloading ship operation, this makes small modules or piling bar when the operation of loading, unloading ship, the dependence of large caterpillar or crane barge is increased greatly, this not only makes Large-scale Hoisting device resource more nervous, and, limit the cycle of small modules or piling bar loading, unloading ship, increase cost and incur loss through delay construction speed simultaneously.
Summary of the invention
Main purpose of the present invention is the above-mentioned shortcoming overcoming prior art existence, and a kind of quay transportation technique of slender structure thing is provided, it can not only by slender structure thing in loading, unloading ship process, avoid contacting with bearing capacity lower region, wharf apron, overcome the impact of Lack of support on the operation of slender structure thing loading, unloading Ship Transportation, solve the not enough problem that Conventional marine engineering structure relies on crane barge loading, unloading ship; And, greatly alleviate the nervous present situation of resource of crane barge and crawler crane, reduce the use cost of the medium-and-large-sized crane barge of traditional approach; Meanwhile, ensure that the shipment cycle of slender structure thing, guarantee its stability and safety.
The object of the invention is to be realized by following technical scheme:
The quay transportation of slender structure thing, a handling technology, is characterized in that: adopt following steps:
The first step: barge and slender structure thing are all completed in place perpendicular to harbour direction, and make slim-lined construction thing and barge line of centers point-blank;
Second step: be arranged in bottom slender structure thing by the 3rd, the 4th liang of group jacking slide device being parked in land, first, second two groups of jacking slide devices are arranged on barge in addition, and complete debugging efforts;
3rd step: arrange H profile steel on barge desired location;
4th step: while the 3rd, the 4th liang of group jacking slide device is placed in a high position, by slim-lined construction thing jack-up, and halt when being transported to bearing capacity lower region, wharf apron, now, first, second two groups of jacking slide devices are in low level armed state;
5th step: first group of jacking slide device jack-up is placed in high-end trim, and the 3rd group of jacking slide device decline is placed in low-end trim, then, the weight of slender structure thing is transferred to first group, the 4th group two groups of jacking slide devices from the 3rd group, the 4th group two groups of jacking slide devices, completes first time weight transfer process;
6th step: slim-lined construction thing continues to transport on barge by first group, the 4th group two groups of jacking slide devices, when the 4th group of jacking slide device closes on the 3rd group of jacking slide device, halts;
7th step: second group of jacking slide device jack-up is placed in high-end trim, 4th group of jacking slide device declines and is placed in low-end trim, the weight of slender structure thing is transferred on first group, second group two groups of jacking slide devices from first group, the 4th group two groups of jacking slide devices, completes second time weight transfer process;
8th step: by two groups of jacking slide devices (1A, 1B) slim-lined construction thing 2 is transported to the on-station position on barge 3;
9th step: synchronously declined by first, second two groups of two groups of jacking apparatus and be placed in low-end trim, then, falls to slim-lined construction thing in the H profile steel of layout in advance, and completes fixing, terminate shipment process.
The model of described jacking slide device is: SS650 type, and this jacking slide device can complete two actions usually: one is module jacking, and another is module slippage.
In described 5th step, the concrete steps of first time weight transfer are:
1. the 3rd group, the 4th group two groups of jacking slide devices being parked in land are placed in high-end trim, and first group, the second group two groups of jacking slide devices be arranged on barge are placed in low-end trim
2. the first group of jacking slide device being in low-end trim is adjusted to high-end trim, now, three groups of jacking slide devices are in high-end trim simultaneously, and form 6 supports;
3. the 3rd group of jacking slide device being in high-end trim is dropped to low-end trim, now, first group, the 4th group two groups of jacking slide devices are placed in high-end trim simultaneously, complete first time weight transfer process.
In described 7th step, the concrete steps of second time weight transfer are:
(1) first group, the 4th group two groups of jacking slide devices are in high-end trim, second group, the 3rd group two groups of jacking slide devices are in low-end trim;
(2) the second group of jacking slide device being in low-end trim is adjusted to high-end trim, now, first group, second group, the 4th group three groups of jacking slide devices are in high-end trim simultaneously, form 6 supports;
