Abstract
The invention relates to a method for building offshore deep water channel, comprising building two dykes against sand with rubble slope protection and dipping deep water channel between two dykes according to the demand of ship navigation. Said building dyke against sand is the building promotion spur dike as hydraulic sliding promotion spur dike sheet with sliding channel, sliding plate, flow pipe, water distribution pipe and separating-water channel is combined with spur dike plate to enter into the stratum. Firstly, the promotion dike plate fabricated according to design is slung by special construction machine for hydraulic sliding plate; secondly, high pressure water pump is run so that high pressure water is jetted from jetting port distributed on the water distribution pipe to cut the stratum out through flow pipe set in the promotion dike plate and the water distribution pipe on the low end of flow pipe, and the promotion dike plate is sent to the presetting depth of stratum; thirdly, the second promotion dike plate is slung, of which at one side presetting sliding plate inserting into the sliding channel preset on the one side of the first plate, and it is sent into the stratum by the same method, now promotion dike is formed; fourthly, spur dikes insert into two side of promotion dike plate, the connecting position of two plate combination is integrated connection, then grout loaded by special film bag is use to envelop two separating-water channels at the connection position of two plates so as to form inner cavity isolated with outside completely; finally, pipe is sent into the cavity and the grout is jetted from bottom to top so as to form concrete whole structure with sandwich steel plate at the connection position of two plates.
Description
One, technical field
The present invention relates to marine harbor approach construction project, relate in particular to a kind of method of building deep sea passage.
Two, background technology
The depth of water situation in navigation channel has extremely important influence to building marine port and pier, solve the not enough problem of fairway depth and mainly contain two kinds of methods at present, a kind of is to adopt dredge boat to desilt and dredge to form the navigation channel, frequent alluvial can appear in the navigation channel that this method forms, and is difficult to form stable deep water fairway; Another kind is to build two navigation channel sediment trapping dykes and dams at sea, forms the navigation channel between two dykes and dams.This method can be built up stable deep water fairway, and entrance of Changjiang River, the PORT OF HUANGHUA of the river mouth, Mississippi of the U.S., China all is to adopt this method to build.But the subject matter that it exists is that difficulty of construction is big, the construction costs height, construction period is long, the safety and stability problem is not easy to solve, there are two fatal weakness in particularly this dykes and dams: the one, and the dykes and dams basis is placed on the ground, seabed, dam configuration is placed by combinations such as one one rubble and concrete barrier board, concrete twist-shaped blocks and is formed, and under the effect that current scour is at sea emptied, exists the unstable problem in basis; The 2nd, there is the not firm problem of dam body in dykes and dams under the stormy waves percussion.
Three, summary of the invention
The technical problem to be solved in the present invention provides that a kind of construction costs is low, speed of application is fast, can guarantee the method for the sediment trapping dam construction deep sea passage of safety and stability performance, adopts hydraulic sheeting to insert and forms navigation channel sediment trapping dykes and dams in the stratum, seabed.
The method of construction deep sea passage of the present invention, comprise that building two is provided with the sediment trapping dykes and dams of rubble mound and need designs the deep water fairway that scrapes out according to ship's navigation between it, the construction of described sediment trapping dykes and dams is with being provided with slideway, slide plate, cross water pipe, the hydraulic sheeting longitudinal dike plate in water yield distribution pipe and water proof road and groynes harden to close and are lowered to the stratum, build along groynes, earlier with the special-purpose construction operation facility of hydraulic sheeting, to connect water supply line by the prefabricated longitudinal dike plate of design, sling, start high-pressure hydraulic pump, make water under high pressure by being arranged at the water yield distribution pipe of crossing water pipe and lower end in the longitudinal dike plate, cut the stratum open from the spray-hole ejection that distribution pipe distributes, and the longitudinal dike plate is lowered to the predetermined degree of depth in stratum, lift by crane second block of longitudinal dike plate then, the default slide plate of one side is inserted in the default slideway of first plate one side, use the same method and be lowered to the stratum, form longitudinal dike like this, insert the groynes plate in longitudinal dike plate both sides by design, implement whole the connection in two plate joint portions, use special-purpose film bag again, two water proof roads of dress cement paste sealing two plate joint portions, form and outside inner cavity chamber of separating fully, in inner cavity chamber, be lowered to pipeline then, fills with water mud from bottom to up, make two plate joint portions form a kind of concrete overall structure that has sandwich steel plate, the rubble of jettisoninging in its both sides again forms the bank protection of certain altitude.
Wherein, described groynes plate is to insert the stratum in the one side near the longitudinal dike plate, inserts the groynes plate at interval 1-5 piece or by the longitudinal dike plate side of the spacing distance of designing requirement.Described groynes plate top can be the beveled structure, also can be trapezoidal, flat shape structure.The also available hydraulic sheeting T of described sediment trapping dykes and dams shape plate inserts the stratum, forms T shape dam.Described T shape hydraulic sheeting inserts the stratum in the mode that intermeshes.Described T shape plate top surface is the beveled structure.
The present invention compared with prior art has following advantage:
1, the embankment safety stability obviously strengthens, because the ground degree of depth is gone into considerably beyond the height of the above dykes and dams in ground in the basis, the problem of effectively having avoided the hydraulic sheeting dykes and dams to be pushed over by stormy waves, do not exist the basis to be washed away the problem of emptying, dam body is the steel bar concrete overall structure, does not also exist by the problem of stormy waves impact failure.
2, construction costs is low.At the navigation channel sediment trapping dike of the equal same absolute altitude of depth of water marine site construction, construction costs can reduce more than 70%.
3, speed of application is fast.The dykes and dams agent structure is the prefabricated profiled reinforced concrete slab in ground, owing to adopted the special hydraulic sheeting facility that advance a technology and special use to construct, the engineering construction cycle can shorten more than 80%.
4, maintenance workload was few after engineering construction became, and operating cost is low.
5, can form stable deep water fairway between two sediment trapping dykes and dams.
