Integrated casing board type long piled wharf

Abstract

This invention belongs to the marine conveyance industry, it concretely relates to the design of the high peg dock and its construction technology. The characteristic of it is as follows: Its upper side adopts the whole pre-stressed box board structure, and consolidates longitudinally along the dock. It is designed according to the short match method and prefabricated construction of box beam. During the segmented prefabrication, it can form the cross pre-stressed component. After finishing the longitudinal segmented prefabrication on the base of peg, the pre-stress is stretched in the residual hole or pipe, and this can form longitudinal prefabrication. There is three-dimensional prefabricated fiber concrete at the conjunction of the whole box board and peg base, and a standard upside structure of dock can form a whole box board after the finishing of construction. The effect and benefit of this invention are effectively improvement of the durability of the dock, and it overcomes the durability of the high peg dock which troubles the marine conveyance many years.

Description

technical field [0001] The invention belongs to the technical field of water transportation engineering, and in particular relates to the design and construction of high pile wharf structures. Background technique [0002] The high pile structure is a structural form commonly used in wharf engineering, and it is mainly suitable for soft foundations. The high-piled wharf is mainly composed of pile foundations and superstructures. Among them, the technology of pile foundations has developed rapidly. Depending on the conditions and conditions of use, different pile types can be selected to meet the use requirements; however, the superstructure technology of high-piled wharfs is developing slowly, and there are few structural forms to choose from. So far, beam-slab structures are basically used. After decades of practice, the traditional beam-slab structure has the following problems to be solved: 1. The bottom contour of the superstructure of the wharf is complicated, and ther...

AI Technical Summary

Problems solved by technology

After decades of practice, the traditional beam-slab structure has the following problems to be solved: 1. The bottom contour of the superstructure of the wharf is complicated, and there are many spaces where salt spray and humid air can accumulate, which has poor durability and short service life; 2. Poor integrity, The rigidity is small; 3. The workload of water construction is large; 4. The workload of cast-in-place joints is large; 5. The construction speed is slow
