Description
Technical Field
The utility model belongs to the port engineering field relates to a novel assembled high stake beam slab wharf structure.
Background
The conventional high-pile beam-slab wharf is one of the main structural forms of the high-pile wharf, and a series of long piles are driven into a foundation to form a foundation to bear the load transmitted from an upper structure, wherein the upper structure generally comprises pile caps, cross beams, longitudinal beams, ship-leaning members, panels, surface layers and the like.
1. The traditional structure description and construction process has the advantages and disadvantages that:
the traditional superstructure mostly adopts two structural forms:
one is a water cast-in-place pile cap, which is divided into a whole span and prefabricated with a beam, a longitudinal beam and a cast-in-place concrete joint. The transverse beam is usually directly placed on the pile or pile cap and combined with foundation pile to form transverse main body structure, the longitudinal beam is generally supported on the transverse beam, but with the increase of wheel pressure of loading and unloading machine, the height of longitudinal beam is almost similar to that of transverse beam, and all the longitudinal beam and transverse beam are supported on the pile (pile cap) to form grid beam with space structure, and the face plate is placed on the transverse beam and longitudinal beam, and mainly directly bears concentrated load action of loading and unloading machine, etc.
The main disadvantages of this construction are: 1. the cross beam, the longitudinal beam and the panel need to be prefabricated in a prefabricated field, the self weight of the components is large, and hoisting equipment needs to meet corresponding hoisting requirements; 2. the construction method is characterized in that a water ship is transported to a site, a large-sized crane ship is needed for operation and installation, the component installation efficiency, the installation efficiency and the installation accuracy are greatly affected by the single loading capacity of the component transport ship and the operation performance of the crane ship besides the influence of the cross operation of a cast-in-place procedure in the operation process, the different models of ships needed by different projects often occur, the universality of equipment is lacked, and the dispatching cost of ship equipment is increased.
The second structure form considers adopting a cast-in-place process form, and can utilize a cast-in-place lower beam to replace a pile cap: the construction process mainly comprises the following steps: pile sinking → pile core concrete construction → cast-in-place lower beam → prefabricated installation of the mooring element → cast-in-place longitudinal beam (track beam) → cast-in-place upper beam → cast-in-place panel → cast-in-place slab joint and surface layer casting → installation of wharf auxiliary facilities and the like.
The main disadvantages of this construction are: although large hoisting equipment and hoisting ships are not needed, the overwater cast-in-place quantity is large, and the construction period is short due to the influence of factors such as overwater mixing capacity restriction, reduction of the number of effective operation days in the whole year and the like. When the wharf structural design specification (JTS167-2018) requires that the upper structure is integrally cast with concrete on site, the number of the structural sections is not larger than 35m, the number of pile foundations is increased, the construction cost is high, the number of overwater construction procedures is large, and on-site workers, techniques and managers are large, so that the standardized management is difficult, and the on-site safety and the engineering quality are difficult to control.
2. Analyzing the advantages and disadvantages of the structure stress:
firstly, as a port develops to deep water, the size of a beam plate of the wharf is increased, the influence of the rigidity of each component on the integral internal force distribution of the integral structure of the wharf cannot be ignored, and the current design and calculation considers selecting a structure section to calculate according to a space structure and fully considers the mutual influence of the space of each component. At present, in the construction process, particularly for precast beam plates, a rigid support continuous beam is formed by pouring joint concrete after the precast beam plates are prefabricated and installed in a span-divided mode, and the difference exists between the rigid support continuous beam and a calculation simulation continuous rod piece; the pile cap is connected with the upper component or the cast-in-place joint through the embedded overhanging steel bar of the pile cap, and is connected with the lower pile foundation through the overhanging steel bar of the pile top; the pile top overhanging steel bar can not be directly connected with the upper component, the longitudinal beam, the pile cap and the pile can not be integrally and rigidly connected, and the structural integrity of the upper part is to be improved.
Secondly, the pile cap is taken as a permanent structure in the traditional structure form, the stress condition of the pile cap is complex, the size, the longitudinal and transverse reinforcing bars of the pile cap are obviously increased for resisting larger external force and bending moment, and the construction cost is correspondingly increased.
And thirdly, reserving reinforcing steel bars at the prefabricated beam slab component, and welding the reinforcing steel bars at cast-in-place nodes. Most overseas processes adopt international general specifications, and part of the international specifications consider that the brittleness of joints is increased after steel bars are welded, the defects of undercut, slag inclusion, incomplete welding seams and the like are easily generated during welding, and the joints are easily brittle and broken under the action of external force; mechanical connection is required to replace welding, so that the existing code structure type has construction problems.
3. Novel structure simplification and defect analysis

The invention has the following disadvantages: the types of the prefabricated parts are different, so that the construction difficulty is increased; the integral construction condition and the stress condition of the L-shaped prefabricated part of the cantilever part are poor; the connection between the lower pile foundation and the prefabricated composite beam is not considered, and the prefabricated composite beam is difficult to install under the condition of low water level.
