Abstract
The present invention discloses a pile supporting cylinder large wharf structure which is composed of a pile foundation, an upper structure, panels and other wharf accessories, wherein the upper structure is formed by arranging prefabricated concrete cylinders along the direction of a wharf shoreline (cylinder axial lines are perpendicular to the wharf shoreline); adjacent cylinders are connected through a poured concrete block body; each cylinder is supported on 2 to 12 top pile caps which are arranged on an oblique pile foundation by pairs; the inner side of each cylinder in the supporting position of the pile foundation is provided with a reinforcing annular beam; the upper parts of the cylinders are provided with concrete longitudinal orbit beams and the panels; concrete blocking walls are constructed on both ends of spaces among the panels and two adjacent cylinders; sandrock material is filled in the middle. The present invention is suitable for constructing large wharves on soft soil seabed foundations. The upper space of a wharf has the advantages of large space dimension, light weight, good integrity, high bearing capacity, good durability, easy construction and correspondingly low engineering cost.
Description
Technical field
The present invention relates to a kind of cylinder large pier structure of pile bearing.Belong to the building structure in the port works field.
Background technology
At present, the large pier form of structure that adopts in the engineering has two kinds, i.e. gravity structure and piling strtucture.Gravity structure bearing capacity height, good endurance, but need reasonable foundation.Piling strtucture is applicable to soft foundation.
Traditional pile foundation wharfs are made up of pile foundation and superstructure, and superstructure can be the solid concrete piece, are called the highrise pile cap structure, or for beam in length and breadth adds the structure of panel, are called the high-pile beam structure.For large-scale pile foundation wharfs, highrise pile cap structural meterials consumption is big, from great, requires the bearing capacity height of pile foundation, and the on-site concrete amount of building is big, the construction cost height; The high-pile beam structural-load-carrying capacity is limited, and very responsive to overload, durability is relatively poor, and the maintenance workload of operating period is bigger.For off-lying sea large-sized deep water harbour, also require harbour end face absolute altitude higher, if satisfy by increasing pile foundation length, then the drift of the above stake of mud face increases, harbour is under boats and ships mooring force or impact effect, bigger moment of flexure to occur in the pile body, and so just need the section of stake is strengthened, increase the pile foundation cost; If satisfy the requirement of harbour end face absolute altitude by increasing superstructure, then the material usage of superstructure will strengthen, and the cost of superstructure increases on the one hand, and on the other hand, the deadweight of superstructure also strengthens, and the bearing capacity of pile foundation also requires to improve.
So for the large-scale pile foundation wharfs on the deep water soft foundation, superstructure should be accomplished bigger space scale, in light weight, good integrity, anti-bending bearing capacity height, good endurance, is easy to construction.The present invention will solve the problem of these aspects.
Summary of the invention
The object of the present invention is to provide a kind of cylinder large pier structure of pile bearing, adopt the harbour of this structural shape to have the superiority of supporting capacity height, structure tension performance and good endurance, have simultaneously easy construction, the characteristics that construction costs is relatively low again.
For achieving the above object, the present invention is realized by following technical proposals: the cylinder large pier structure of pile bearing, form by pile foundation, superstructure, panel and other harbour ancillary facility, it is characterized in that, superstructure is formed along the frontage direction and with cylinder axis and frontage vertical arrangement by the precast concrete cylinder, connects by the concret block of building between adjacent cylinders; Each cylinder is supported on the top pile cover of 2 to 12 groups of oblique pile foundations arranged in pairs, in the cylinder inboard of pile foundation bearing position strengthened ring beam is set; Concrete long rails beam and panel are established in cylinder top; The concrete wall is built, middle heap sand building stones in the two ends in the space between panel and adjacent two cylinders.
The drum diameter of above-mentioned accumbency precast concrete is 2m～16m, and length is 8m～50m, and wall thickness is 0.1m～1.0m.
In the space between above-mentioned panel and adjacent two cylinders, put the precast concrete cylinder of a minor diameter earlier, the crest level of little cylinder is not higher than the crest level of large cylinder, the diameter of little cylinder is 0.2 to 0.5 times of large cylinder diameter, the concrete wall is built, middle heap sand building stones in two ends in the space of remainder.
Superiority of the present invention is: the cylinder large pier structure of pile bearing, be suitable in weak soil sea bed ground or Deepwater Open Sea environment, building large-scale pile foundation wharfs, the harbour of this structural shape has the advantage of supporting capacity height, structure tension performance and good endurance, have simultaneously easy construction, the characteristics that construction costs is relatively low again.

The specific embodiment
One embodiment of the invention is as follows: the cylinder large pier structure of a pile bearing as shown in Figures 1 to 4, it is made up of pile foundation, pile cover, concrete cylinder, longitudinal beam, panel and other harbour ancillary facility.Wharf apron mean depth 22m, pile foundation is the steel pipe pile of diameter 1.4m, the concrete pile follower end face of preceding campshed is apart from mud face 24m, the pile foundation segment length 28m that buries; 4 pairs of 8 gradients are the accumbency accumbency concrete cylinder diameter 10m of the taper pile supporting of 1: 3 and 1: 5, long 36m (being the width of harbour), wall thickness 0.3m, 4 road strengthened ring beams are arranged in the pile bearing place cylinder, and its section is trapezoidal shape, highly is 1.0m, top width 0.5m, bottom width 2m; The minimum outer wall spacing that cylinder is arranged is 0.5m, with the elongated cast-in-situ concrete that highly is 2.0m adjacent two cylinders is connected; The outer upside of the front row of distance harbour leading edge and each 3m of trailing edge and adjacent two cylinders of back campshed bearing position build the thick concrete wall of 0.5m to the harbour end face as the long rails beam, establish the track of loading mechanization walking on the beam, two the track space 30m in front and back; Space between the twice concrete wall is filled closely knit with the sandstone material, on establish panel, constitute the harbour end face.
This harbour can be stopped the boats and ships of 20 tons, can install corresponding loading mechanization on the harbour, also can act on 80kN/m on the harbour face
2Cargo load.
The cylinder large pier structure of pile bearing is suitable for building large pier on weak soil sea bed ground, the upper space yardstick of harbour is big, in light weight, good integrity, bearing capacity height, good endurance, be easy to construction, engineering cost is relatively low.
