The specific embodiment
The utility model steel truss embedding rock dock structure comprises following structure, hereinafter is described in detail with reference to the accompanying drawings.
The utility model relates to the steady stake of the socketed pile 2 beddings technology of a kind of deep-water bare basement rock or the more shallow geological environment of basement rock covering layer, is suitable for opening wide in the off-lying sea large-scale long piled wharf or the bridge of building on the shallow covering batholith in waters or exposed batholith.
As shown in Figure 2, set up horizontal support 13 and oblique support 14 on column 11, reduce the drift of column 11, strengthen horizontal rigidity and the globality of structure, make structure stress more reasonable.Steel pipe is adopted in horizontal support 13 and oblique support 14, is welded to connect fixing between steel pipe and steel pipe.
The steel truss structure unit makes on land, then carries out over-water construction and is arranged on through repairing on smooth bedding, and like this, the water project amount is little, and technical risk is little, has certain capacity of anti-storm.
Steel truss embedding rock dock structure construction process is: preparation of construction, underwater foundation levelling, steel truss 1 are made, steel truss 1 transports, steel truss 1 is installed, the embedding rock is constructed, harbour superstructure 5 is constructed, ancillary service is installed.Concrete operation step is as follows:
1) steel truss 1 underwater foundation levelling.When steel truss 1 is installed the natural ground out-of-flatness in waters, leveling layer 33 should be set.Leveling layer 33 can adopt throwing rubble or cast Underwater Concrete.The planeness of leveling layer 33 and intensity thereof need satisfy the construction requirement of steel truss 1, and mud mat 15 can be considered to configure in steel truss 1 column 11 bottoms.
2) steel truss 1 processing and fabricating.Steel truss 1 is made and should be selected suitable place, and considers to store and go out arc manipulation spare.Can at shipyard or produce in factory, also can process in interim prefabricated place.Node 12 welding of horizontal support 13 and oblique support 14 should be undertaken by technical measures such as the method for welding procedure regulation, program, parameter, checks.
3) steel truss 1 transportation.According to steel truss 1 size and the suitable constructure scheme of ambient conditions establishment, guarantee safety.Steel truss 1 water transportation can be adopted the methods such as crane ship handling, barge carrying and transportation by driving.
4) steel truss 1 installation waterborne.The general crane barge that adopts lifts, and needs natural ground is carried out levelling under water before installing.Steel truss 1 is installed and should be selected trend little, and the period that tidal level is low, stormy waves is little is carried out operation.After steel truss 1 puts in place, should carry out the leveling operation, its horizontal error should be in the design allowed band.
5) at the water area condition that The water is deep and the current fast, after installing, steel truss 1 should take certain engineering measure to guarantee steel truss 1 monolithic stability, should before arriving, during typhoon period complete Anti-Typhoon required Pile simultaneously.
6) the embedding rock of the column 11 of steel truss 1.After installing, steel truss 1 can be used as operation platform, the double sleeve of doing socketed pile 2 of the column 11 of steel truss 1, arrange that rig carries out basement rock boring along the column 11 of tubulose, then carry out the construction of embedding rock, insert boring in and fluid concrete along the cavity of column 11 the socketed pile reinforcing cage.The diameter dimension of the embedding rock degree of depth and socketed pile 2 all reduces than prior art, has reduced difficulty of construction.
7) when steel truss 1 is prefabricated, the template processing of the cast-in-place structural of harbour superstructure (5) can be completed simultaneously according to construction technology, to reduce over-water construction workload, accelerating construction progress.
Above-mentioned design example only is used for the utility model is described, and does not consist of the restriction to the claim scope, and other substantial equivalence means that it may occur to persons skilled in the art that are all in the utility model claim scope.
