Description
Technical Field
The utility model belongs to the technical field of bridge construction, relates to bridge underwater pile foundation construction, and in particular relates to a deep water pile foundation reinforcement cage lowering and back pressure suspension cage.
Background
The construction of the pile foundation drilling in water requires inserting and beating a steel pile casing, the upper end of the steel pile casing is higher than the water surface, and a drill bit of a drilling machine drills downwards along the steel pile casing; and after pile hole construction is completed, a reinforcement cage is placed in the hole, and pile foundation concrete is poured.
When pile foundation concrete is poured, back pressure is needed to be carried out on the reinforcement cage in order to prevent the reinforcement cage from floating upwards. Because pile top elevation of the pile foundation in water is lower than the water surface, a common back pressure mode is to directly lengthen the uppermost section of steel reinforcement cage of the pile foundation to a steel casing nozzle, and limit clamps are arranged at the steel casing nozzle to back pressure the steel reinforcement cage; after pile foundation concrete pouring is completed, constructors cut off the lengthened portion reinforcement cage in the steel casing. The steel cage steel pile casing has small space, so that the work difficulty is high and the time consumption is long; for deep water pile foundations, the length of the extension part of the reinforcement cage is generally more than 10m, and the cut reinforcement cage is difficult to reuse, so that great waste is caused.
Disclosure of Invention
The utility model aims to solve the problems, and provides a deep water pile foundation reinforcement cage lowering and back pressure hanging cage which is used for lowering the uppermost section of reinforcement cage of a pile foundation, can back pressure the reinforcement cage, is convenient to install and detach and reduces material waste.
The technical scheme of the utility model is as follows:
the utility model provides a deep water pile foundation steel reinforcement cage descends and back pressure cage which characterized in that: the pile foundation reinforcement cage comprises at least two hoops, the diameter of each hoop is consistent with the diameter of a pile foundation reinforcement cage, a certain distance is reserved between each hoop, the axes of the hoops are opposite, 4 pairs of hanging bars are welded at equal intervals in the circumferential direction, the hanging bars are parallel to the axes of the hoops, each pair of hanging bars comprises two reinforcing bars, a lifting lug is welded between the upper ends of the two reinforcing bars of each pair of hanging bars, an upper connecting plate is longitudinally welded between the lower ends of the two reinforcing bars along the reinforcing bars, a certain length is extended from the lower ends of the upper connecting plate to the lower sides of the hanging bars, and two pin holes are formed in the parts, below the hanging bars, of the upper connecting plate.
The utility model is connected with the reinforcement cage by a bolt, so that the quick disassembly is convenient after the pile foundation concrete pouring is finished; the structure is light, the rigidity is strong, the deformation is not easy, and the effective back pressure can be carried out on the reinforcement cage; can be repeatedly used, and can save the construction cost of pile foundations.

FIG. 2 is a schematic top view of the present utility model;
fig. 3 is a schematic view of the use state of the present utility model.
Detailed Description
As shown in fig. 1 and 2, the utility model comprises at least two hoops 1, the diameters of the hoops are consistent with the diameters of pile foundation reinforcement cages, a certain interval is arranged between the hoops, the axes of the hoops are opposite, 4 pairs of hanging bars 2 are welded in the circumferential equidistant mode on each hoop, the hanging bars are parallel to the axial line of the hoops, each pair of hanging bars comprises two reinforcing bars, a lifting lug 3 is welded between the upper ends of the two reinforcing bars of each pair of hanging bars 2, an upper connecting plate 4 is welded between the lower ends of the two reinforcing bars of each pair of hanging bars 2 longitudinally along the reinforcing bars, a certain length extends from the lower ends of the upper connecting plate to the lower sides of the hanging bars, and two pin holes 41 are formed in the parts of the upper connecting plate 4 extending to the lower sides of the hanging bars.
In the processing of the utility model, the hoop can be formed by adopting angle steel; the length of the hanging bar is not less than the height from the design elevation of the pile top to the opening of the steel casing.
As shown in fig. 3, 4 pairs of main ribs 6 are selected on the uppermost section of reinforcement cage 5 of the pile foundation, the upper ends of each pair of main ribs are lengthened, a lower connecting plate 7 is welded between the upper ends of each pair of main ribs 6, two pin holes 71 are formed in the lower connecting plate 7, and the pin hole spacing on the lower connecting plate is consistent with the pin hole spacing on the upper connecting plate.
When the pile foundation reinforcement cage is lowered in sections by adopting a conventional process, and the uppermost reinforcement cage is lowered, the lifting cage is lifted by a crane, the pin holes 41 on the upper connecting plate 4 of the lifting cage are aligned with the pin holes 71 on the lower connecting plate 7 of the uppermost reinforcement cage and are connected by bolts, the lifting cage is lifted by the crane to lower the uppermost reinforcement cage, after the reinforcement cage is lowered in place, the upper end of the lifting cage is positioned at the cylinder mouth of the steel casing, and the limiting clamp is arranged at the cylinder mouth of the steel casing to limit the upper end of the lifting cage, so that the back pressure of the reinforcement cage is realized, and the floating cage is prevented from occurring during concrete pouring.
Pouring pile foundation concrete, and taking down the connecting bolt of the suspension cage and the steel reinforcement cage in the steel casing by constructors after the concrete is initially set, and hoisting the suspension cage to the next construction point.
