Description
The invention belongs to the job practices of open caisson and coffer work.
It mainly is applicable to Structures in Port Engineering, also is applicable to the construction of the building that is made of a plurality of open caissons or caisson in the civil engineering.
Here be that example compares and narrate characteristics of the present invention with the port works.
General Structures in Port Engineering, as harbour (berth), existing building method kinds such as mole, shore protection, bulkhead wall are more, but all exist the problem that compliance is relatively poor, construction cost is big.As present widely used caisson job practices, exist following shortcoming: (1) is along with the increase of caisson volume and weight, its manufacturing, following water, transportation, in place and denidation all need large scale prefabricated factory (field) or dock, large-scale special purpose ship, large-scale floating crane etc., making construction become difficult; (2) because of caisson weight is big, drinking water often is subjected to the restriction of dock and fairway depth deeply during transportation; (3) caisson need be established riprap foundation, and the smooth amount of its earthwork and bedding is big, is unfavorable for rapid construction; (4) temporory structure and large-scale special equipment are many, cause the operating expenses height, and the working procedure complexity.Square gravity and sloping breakwater construction method for another example also exist shortcoming: it is many that (1) consumes building stones; (2) depth of water is big more uneconomical more.For another steel sheet pile and steel sheet pile lattice body structure job practices, also exist the some shortcomings part: (1) integral rigidity is poor, constructional difficulties under the big flood deep feeling condition; (2) etching problem is arranged in seawater; (3) aspect anti-seismic performance, X factor is arranged; (4) on batholith or at offshore construction, have any problem.Also have steel caisson structure job practices, have only under special circumstances and just use, uneconomical in general.
Recently develop and a kind of many formulas lattice body structure job practices that belongs to the open caisson class, than said method have large improvement.Belong to the shell structure that does not have base plate as (1), good integrity, smooth less demanding to riprap foundation, easier denidation in place; (2) caisson of the same size that compares, its towage depth of water in light weight can be littler, and following water, towage, capacity of equipment in place and that denidation is required are also little; (3) because the length of many formulas lattice body is equivalent to the length of 3～5 caisson combinations, thereby reduce sea faring number of times, can shorten the construction period, reached economy purpose fast.But this kind job practices also exists some shortcoming, as (1) also need establish riprap foundation and increase bedding and many formulas lattice body between the underwater grouting measure; Need the increased area seal cover during (2) automation process of towage and denidation in place requirement height, and towage; (3), thereby need more large-scale floating dock or crane barge (Japan has built ton floating dock and four kiloton crane barges for this reason) because the weight of many formulas lattice body is equivalent to the weight of 2～4 caissons.
A common ground of above-mentioned Structures in Port Engineering job practices is exactly that the water surface and underwater operation amount are big, and professional equipment is many, and professional technical is strong, influenced greatly by the stormy waves regimen.
The application of open caisson and coffer work is also a lot of in the civil engineering, and as some hydraulic structure in the Hydraulic and Hydro-Power Engineering, the leg of intake strucure, sewage pumping station, large equipment base, underground structure etc. all have the construction of the drop shaft sinking of employing.The construction of open caisson in the civil engineering also needs more equipment and facility, working procedure also very complicated.
