Abstract
The present invention belongs to the field of marine traffic engineering, particularly to the design of a high-plied wharf and a construction technique thereof. The present invention is characterized in that the upper structure adopts a bidirectional prestressed integral box plate type structure which is assembled in subsections along the wharf in the longitudinal direction, and the present invention is designed according to a slug matching box girder prefabricating construction technique. When a longitudinal subsection is prefabricated, a transverse prestressed member is formed. After the prestressed longitudinal subsection is installed on a pile foundation, prestressing force stretching is conducted in a prepared hole and a pipeline, and the longitudinal prestressing force is formed. Prestressed fiber concrete is adopted in the connecting position of the integral box plate and the pile foundation. After the construction is finished, the upper structure of a standard section wharf forms the integral box plate. The present invention has the effect and the benefit that the durability of the wharf can be improved, and the problem of the durability of the high-piled wharf which troubles the marine traffic industry for many years is solved.
Description
Technical field
The invention belongs to the marine traffic engineering technical field, specially refer to the design and construction of high pile pier structure.
Background technology
High pilework is a kind of form of structure that the harbour engineering generally adopts, and it mainly is applicable to soft base.Long piled wharf mainly is made up of pile foundation and superstructure, wherein the pile foundation technology development is very fast, design and construction technology such as reinforced concrete pile, prestressed reinforced concrete stake, prestressing force Big Pipe Pile, steel pipe pile are day by day ripe, adapt to different geological conditionss and service condition, select for use different stake types can reach instructions for use; But the technical development of long piled wharf superstructure is slow, and alternative form of structure is less, up to the present, all adopts the beam and slab type structure basically.Through the practice of decades, it is to be solved that traditional beam and slab type structure exists following problem to have: 1. harbour superstructure return pulley is wide complicated, and the many spaces that can gather the salt fog moisture laden air are arranged, poor durability, and application life is short; 2. globality is poor, and rigidity is less; 3. the over-water construction workload is big; 4. cast-in-place joint workload is big; 5. speed of application is slower.
Along with developing rapidly of Chinese national economy, the application meeting of long piled wharf is more and more wider, and the problem that how to solve the Durability of High-pile Wharf difference is that present China water transport industry is badly in need of one of subject matter that solves.
Summary of the invention
The purpose of this invention is to provide a kind of novel high pile pier structure that can significantly improve Durability of High-pile Wharf, construction simple and fast, the beam and slab type high pile pier structure of construction costs and existing routine is more or less the same simultaneously.
Technical solution of the present invention is, the harbour superstructure adopts two dimension prestressing boxboard formula structure, along the assembly unit of harbour longitudinal divisions, design by the beam prefabricated construction technology of slug matching case, form the transverse prestress member when longitudinal divisions is prefabricated, prefabricated longitudinal divisions carries out prestressed stretch-draw in the hole of reserving after installing on the pile foundation, form vertical post-tensioned prestressing, make each plate be coupled to an integral body; In whole boxboard and pile foundation junction, prefabricated boxboard reserving hole, the back pouring concrete adopts the three dimension prestressing fibrous concrete in the hole, and after construction was finished, the superstructure of a standard paragraphs harbour formed a whole boxboard.
Effect of the present invention and benefit are: 1. harbour superstructure bottom profile is a plane, can not gather the space of salt fog moisture laden air; 2. adopt two dimension prestressing and high performance concrete, structural entity rigidity is big, service condition good, harbour good endurance, long service life; 3. the aquatic work amount is few, and the cast-in-situ concrete amount is few, and speed of application is fast.In addition, the beam and slab type high pile pier structure of this structural system construction costs and existing routine is more or less the same.

The specific embodiment
Below in conjunction with technical scheme and accompanying drawing, be described in detail the most preferred embodiment of integrated casing board type long piled wharf structure:
A harbour standard paragraphs length is 54 meters, and width is 34.5 meters.Every boxboard width of harbour superstructure is 6 meters, high 1.5m, wherein top board, base plate is thick is 0.3 meter, the horizontal rib width of boxboard is 0.8 meter, vertical rib width is 2.6 meters and 2.2 meters in the stake, it is 0.5 meter and 0.8 meter that rib width is gone up in non-stake.A harbour standard paragraphs is made up of 9 blocks of prestressing force boxboards.The two dimension prestressing boxboard laterally adopts prefabricated prestressing without bondn structure along harbour, vertically adopts the post-tensioning prestress with bond structure along harbour.Superstructure connects into an integral body by the longitudinally on-the-spot post-tensioned prestressing muscle in scene, on whole 54 meters harbour sections, form the whole two dimension prestressing box plate superstructure of a long 54m * wide 34.5m * high 1.5m, have great horizontal rigidity, do not need to be provided with any taper pile.
Prefabricated boxboard is at place, stake top reserving hole, and hole diameter is than the big 0.6m of steel pipe pile external diameter, and back pouring concrete adopts the three dimension prestressing fibrous concrete, makes steel pipe pile and boxboard connect into integral body.
Consider stretch-draw and wear the needs of muscle; the prefabricated boxboard in end at harbour segmentation two ends adopts special-shaped prestressing force boxboard; after prestressed stretch-draw is finished at the scene; cast hole concrete; ground tackle with the protection prestressed cable; form harbour segmentation both ends wide and be 3.4 meters concrete sidewall, guarantee the ground tackle of on-the-spot post-tensioned prestressing, in the whole operating period from now on, can not relax and by corrosion.
