Abstract
The utility model discloses a connection structure of a box girder and a tubular pile, which comprises the box girder, a cross beam, a hollow tubular pile, and is characterized in that the cross section of the box girder is n-shaped; two ends of the cross beam are provided with bearing platforms which are transversely provided with through grooves; the through grooves are internally provided with through holes; two ends of the box girder are respectively embedded into the through grooves of the cross beam; and the cross beam is supported on the hollow tubular pile so as to connect the box girder, the cross beam and the hollow tubular pile into a whole by cast-in-situ reinforced concrete in the through holes. Compared with the prior art, the connection structure has the advantages of having more reasonable structure stress, little using amount of reinforced concrete material, simple and convenient construction and short construction period, reducing pile-sinking dangers, and lowering engineering construction cost.
Description
Technical field
The utility model relates to the hydro-structure technical field, the specifically a kind of box crossbeam of arine railway and connection structure of pile tube of being used for.
Background technology
At present, the slideway crossbeam structural shape that the engineering of slideway under water of conventional ultra-large type building berth is used all adopts solid prefabricated cross beam, it is by longitudinal slipway crossbeam and two slideway structures that transverse strut is formed of two two ends cantilevers, it is installed on the precast reinforced concrete square pile of band major part by behind the cast-in-place point of attachment under water.The hoisting capacity waterborne of single Pin slideway crossbeam of this structural shape is (to comprise that the land and water boundary place is also identical) more than 140 tons, its planar dimension be 9 meters * more than 10 meters, every Pin slideway crossbeam must be installed in aslope 4 under water on the precast reinforced concrete square pile with major part, therefore, the slideway crossbeam structural shape difficulty of construction of prior art is big, setting accuracy is high.Load-carrying ability must reach more than 150 tons and will satisfy certain width of cloth requirement of hanging on the water, preferably there is big part harbour to use for lifting, and the requirement that major part stake under water is prefabricated and pile sinking is located is than higher, its pile sinking positioning requirements will be higher than the regulation of 10 centimeters deviations of permission of national regulation, also has high absolute altitude control requirement, otherwise cross beam will be difficult to guarantee to install stablize, and the major part precast pile can not be repaired if any damage in the pile sinking, the construction costs height.
Summary of the invention
The purpose of this utility model is a kind of box crossbeam that provides at the deficiencies in the prior art and the connection structure of pile tube, it adopts cast-in-situ steel concrete to connect the structure of box crossbeam and hollow shell pill, stressed more reasonable, making under water, pile foundation effectively reduces difficulty of construction, thereby saved material of construction effectively, further reduce construction costs, made easy construction, duration shorten.
The concrete technical scheme that realizes the utility model purpose is: the connection structure of a kind of box crossbeam and hollow shell pill, comprise box crossbeam, crossbeam, hollow shell pill, and characteristics are that the cross section of box crossbeam is " door " font; The crossbeam two ends are provided with cushion cap, laterally are provided with groove on the cushion cap, are provided with through hole in the groove; Box crossbeam two ends are embedded in respectively in the groove of crossbeam mutually, and beam supporting is an one by cast-in-situ steel concrete captive joint box crossbeam, crossbeam and hollow shell pill in the through hole on hollow shell pill.
Described through hole is a truncated cone-shaped.
Described groove and box crossbeam are with wide.
The utility model compared with prior art has the following advantages.
1., crossbeam is connected reliably with pile tube, overall construction intensity improves greatly.
2., help strengthening the stake quantity that pilespacing reduces whole slideway, and can suitably reduce the control requirement of pile sinking, reduced the pile sinking risk, reduce construction costs.
3., construction install convenience, workable, can adapt to various construction situations, the single prefabricated components biggest lifting capacity alleviates, and only must control the planimetric position and the absolute altitude of 2 piles during assembling, but and secondary regulation and control on absolute altitude.

The specific embodiment
Consult accompanying drawing 3, the utility model is to install like this: the cushion cap 4 at crossbeam 2 two ends is placed on the hollow shell pill 3, the two ends of box crossbeam 1 are embedded in the groove 5 of cushion cap 4 mutually, an end of the adjacent two box crossbeams 1 of phase embedding in the groove 5, behind the installation in position in the through hole 6 of crossbeam 2 cast-in-situ steel concrete 7, cast-in-situ steel concrete 7 is fixedly connected into steel concrete integral structure with adjacent two box crossbeams 1 and crossbeam 2, hollow shell pill 3.
