Abstract
A lifting platform system for placing a large caisson in water comprises a plurality of prefabricated platforms and lifting platforms supported in water. One side of the lifting platform leans on the edges of the prefabricated platforms. The tops of the prefabricated platforms and the tops of the lifting platforms are the same in structure and each sequentially comprise a face plate and a truss beam of a mesh structure from top to bottom. The lower sides of the truss beams of the prefabricated platforms are supported by the top ends of steel pipe columns which are arrayed in a matrix mode. The lower ends of the steel pipe columns are hit into a water bottom mud field. The lower sides of the truss beams of the lifting platforms are hinged to the top ends of the lifting rods. The bottoms of the lifting rods with the lower ends extending in the steel pipe columns are supported by a prefabricated concrete foundation at the lower ends of the steel pipe columns through a plurality of supporting bases. Without renting a semi-submersible barge prefabricated and transported large caisson, the prefabricating and transporting cost of the large caisson is greatly reduced, and the transporting safety of the large caisson is improved. After a project ends, the prefabricating platforms and the lifting platforms can be repeatedly used after being detached, and the resource utilization rate is increased.
Description
Technical field
The present invention relates to a kind of lower water transport communication system of box concrete precast element for building large pier, embankment, particularly relating to a kind of large-sized concrete caisson and being transported to plateform system in water from land or pier, belonging to hydraulic engineering technical field.
Background technology
it is prefabricated that Large Caisson is typically chosen in land precasting yard, and then barge transport is dived to half and refuted, and adopts half to dive to refute Large Caisson is transported to waters, erecting bed installs.But some regional population is intensive, available land resources is less, does not have the prefabricated Large Caisson in place be applicable to, need floating afloat half dive refute prefabricated; Though also there are some engineerings can build land precasting yard, do not have large-scale half to dive and refute, even cannot leasing partly dives refutes and has influence on normally carrying out of engineering.Adopt concrete prefabricatedly form the closed box reaching more than 20 meter because caisson is one, can swim on the water surface, but because its thousands of tons of that weighs is to ton up to ten thousand, how heavy caisson descend water to be a great problem of construction hydraulic engineering project.Dive as long-term lease ton half and refute, not only will spend a huge sum of money, and half dives and refute as a raft, because its drinking water area is large, moldeed depth is dark, both sides wing wall is high, and thus wind, flowing water are half-and-half dived and refuted impact very greatly, and its rocking property can have influence on the prefabricated quality of caisson.Meanwhile, the wind in work progress, flowing water half-and-half dive to refute all larger impact, and half dives refutes traction and location of casting anchor in port and all there is larger danger, and running into strong wind needs to hide.Therefore, in the urgent need to research and develop a kind of Large Caisson precasting yard or pier prefabricated, directly descended the system of water by precasting yard harbour or pier, effectively solve the problem.
Summary of the invention

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1 to 4, the present invention includes and be severally supported on prefabricated platform 1 in water and lift platform 2, several prefabricated platform 1 is spliced into a platform harbour, the length of its quantity needed for platform harbour and determining.Lean against on prefabricated platform 1 limit of platform harbour on the left of lift platform 2, prefabricated platform 1 is all obliquely installed with two adjacent side of lift platform 2, to reduce both splicing seams, is convenient to the movement of Large Caisson 3.Prefabricated platform 1 is identical with lift platform 2 top structure, be followed successively by the girder truss 12 of panel 11, network from top to bottom, girder truss 12 comprises crisscross and by the many longerons 121 that are welded and fixed and Duo Gen crossbeam 122, be supported on by welding steel pipe pile 13 top that many become matrix arrangement on the downside of the girder truss 12 of prefabricated platform 1, steel pipe pile 13 can adopt pile driving barge that vibration hammer also can be adopted to be thrown in water-bed mud ground, the wall thickness of steel pipe pile 13, on the basis meeting bearing capacity, should meet piling requirement.The steel pipe pile 13 of lift platform 2 also adopts same method to construct, and difference is, the steel pipe pile 13 of lift platform 2 inserts elevating lever 21, and the steel pipe pile 13 upper end end face of supporting elevation bar 21 is concordant with water-bed mud face.
Elevating lever 21 top becoming matrix to arrange with 12 respectively by latch on the downside of the girder truss 12 of lift platform 2 is hinged, and lateral force when avoiding lift platform 2 to be elevated causes adverse influence to elevating lever 21.Elevating lever 21 lower end puts in steel pipe pile 13.As shown in Figure 1,2 meters of thick concrete foundations 131 are built in bottom the steel pipe pile 13 of supporting elevation bar 21, concrete foundation 131 is placed several bearing 211, and by soldered to bearing 211 and steel pipe pile 13 inwall, be supported on by several bearing 211 bottom elevating lever 21 on the precast concrete foundation 131 of steel pipe pile 13 lower end, 12 become the elevating lever 21 of matrix arrangement to support by the girder truss 12 of lift platform 2 and panel 11 Large Caisson 3 be carried on lift platform 2.
Elevating lever 21 is the lifting plunger cylinder of more piece plunger, to meet the longer needs of elevating lever 21 stroke.Inside there is steel pipe pile 13 internal diameter of elevating lever 21 to be greater than maximum size bottom elevating lever 21, be convenient to elevating lever 21 to insert in steel pipe pile 13.Push up at steel pipe pile 13 pole 23 that mouth is provided with several support cylinder cylinder body, make elevating lever 21 stably remain on plumbness, thus guarantee that lift platform 2 is elevated steadily.
In order to improve the stability that lift platform 2 is elevated further, as shown in Figure 4, lifting and guiding device 22 is also respectively equipped with at the two ends of lift platform 2 side adjacent with prefabricated platform 1, described lifting and guiding device 22 comprises guide collar 221 and junction plate 222, guide collar 221 and lift platform 2 top surface being parallel, be enclosed within the steel pipe pile 13 of the contiguous prefabricated platform lower with lift platform, be welded and fixed on the downside of vertically disposed junction plate 222 upper end and girder truss 12, the extended end of lower end and guide collar 221 is welded and fixed and connects.When lift platform 2 is elevated, the steel pipe pile 13 that guide collar 221 is overlapped along it moves up and down, and prevents lift platform 2 from occurring crooked.
As shown in Figure 2, elevating lever 21 stroke after being greater than Large Caisson 3 times water undersurface depth H 1 and lift platform 2 end face apart from low water stage water surface distance H2 sum.When guaranteeing that lift platform 2 drops to underwater, Large Caisson 3 can swim in waterborne completely, is convenient to tugboat band cable and tows to destination, replaces partly diving of cost of use costliness and refutes.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of application claims.
