Abstract
The utility model relates to a vertical positioning device for a deep water steel hanging box applied in the construction of a tidal river. The vertical positioning device is characterized in that a steel hanging box (1) adopt an integrated jacket-type structure; an interlayer cavity is formed by the double-layered wall plate of the peripheral structure thereof; a well-shaped cross-span beam is arranged in the steel hanging box (1), so that a pile foundation steel protective sleeve (6) passes through the well-shaped cross-span beam; pile top reaction beams (3) are welded at the top ends of the pile foundation steel protective sleeve (6) and a temporary steel pipe pile (2); the top part of the wall plate of the steel hanging box (1) is connected with a back pressure steel beam (5); and the pile top reaction beams (3) are connected with the back pressure steel beam (5) through a positioning upright column (4); and welding stiffener plates (11) are arranged in the welded connection positions of the pile top reaction beams (3), as well as the temporary steel pipe pile (2) and pile foundation steel protective sleeve (6). The vertical positioning device has the advantages of short construction time, and high vertical positioning accuracy.
Description
Technical field
The utility model belongs to large bridge construction equipment technical field, especially a kind of vertical positioner of deep water steel box that is applied in the construction of morning and evening tides section.
Background technology
Along with the continuous development of Bridges in Our Country construction technology, deep water multi-column pier foundation, highrise pile cap obtain very using widely as the main base form of striding the river Oversea bridge.Such bearing platform construction mainly adopts the steel box to enclose the water constructing structure as it.In the morning and evening tides section, because tidal range can reach 2～3m, construction environment brings very big adverse effect for the vertical location construction of steel box.Therefore the location construction of bridge steel box on this class section generally is selected in the time of low water section and carries out.Vertical locate mode in the past often adopts between steel box wallboard and steel casing the welding location structure to position, but because large-scale steel box relative positioning point is more, workload is bigger, if in a time of low water section, finish the welding job of all location structures, just must drop into a large amount of man power and materials, concentrate and carry out simultaneously, not only waste resource, and the also difficult assurance of positioning accuracy, there is bigger construction risk.
Summary of the invention
In order to overcome the long and not high deficiency of positioning accuracy of existing vertical location working procedure duration, the purpose of this utility model provides short, the vertical high vertical positioner of deep water steel box of positioning accuracy of a kind of construction operation time.
The technical solution adopted in the utility model is: design the vertical positioner of a kind of deep water steel box, it is characterized in that: steel box 1 is whole chamber type structure, the double-deck wallboard of its peripheral structure forms the interlayer cavity, well word shape is arranged across beam 10 in the steel box 1, and pile foundation steel casing 6 is passed; Be welded with a top reaction beam 3 on the top of pile foundation steel casing 6 and temporary steel pile tube 2, be connected with back-pressure girder steel 5 in the top of panels of steel box 1, stake top reaction beam 3 is connected by locating column 4 with back-pressure girder steel 5; Stake top reaction beam 3 is provided with welding stiffener 11 with the place of being welded to connect of temporary steel pile tube 2 and pile foundation steel casing 6.
When adopting this device vertically to locate construction, at first select vertical anchor point, at the pile foundation steel casing 6 of anchor point correspondence and welded and installed stake top, the top reaction beam 3 of temporary steel pile tube 2, and utilize stiffener 11 to guarantee firm welding, make it be enough to resist vertical location counter-force; Next installs back-pressure beam 5, makes itself and box wallboard firm welding; According to the length of design elevation compute location column 4, and be transported to the job site in back court processing; When steel box 1 is transferred to floating certainly state, in box wallboard interlayer body cavity, add water rapidly in the low tide period, make steel box 1 sink down into design elevation, and rapid horizontal lock, while installing and locating column 4, make itself and stake top reaction beam 3 and back-pressure beam 5 firm welding, the vertical location of finishing the steel box.
The main feature of the vertical positioner of box of the present invention is that positioner is decomposed processing in advance, the accessory structure of mounting and positioning device in advance, in the time of low water section, only need to install main positioner, reduce workload with this, shorten the operation duration, the vertical positioning operation of box can be finished smoothly fast in the low tide stage; In addition, by calculating the vertical extension of determining the location column, by rigid support and the connection of welding the hierarchy of control, vertical positioning accuracy is enhanced.
Description of drawings
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
Fig. 1 is the facade structures schematic diagram of the utility model device.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1, steel box; 2, temporary steel pile tube; 3, stake top reaction beam; 4, location column; 5, back-pressure girder steel; 6, pile foundation steel casing; 7, construction water surface curve; 8, water surface curve in the steel box wallboard; 9, above-ground route; 10, well word shape is across beam; 11, welding stiffener.
The specific embodiment
As depicted in figs. 1 and 2, a top reaction beam 3 is arranged, back-pressure girder steel 5 is installed, between stake top reaction beam 3 and the back-pressure girder steel 5 column 4 of location is arranged in the top of panels of steel box 1 in the top welded and installed of pile foundation steel casing 6 and temporary steel pile tube 2.
When adopting this device vertically to locate construction, adopt following construction sequence:
2. back-pressure beam 5 is installed at the vertical anchor point place of steel box 1 wallboard, back-pressure beam 5 must with box wallboard firm welding.
3. be transported to the job site according to the length of design elevation compute location column 4, and in back court processing.
5. utilize low slack period,, make itself and stake top reaction beam 3 and back-pressure beam 5 firm welding, the vertical location of finishing the steel box at each vertical anchor point while installing and locating column 4.
