Watertight Caisson for Underwater Pier Construction Work and Dry Construction Method of Underwater Pier Foundation Work Using Thereof

摘要

The present invention is installed in a watertight revocation of the piers in the riverbed and dry while the inside of the water drain foundation or start a dry construction method for building the underwater piers based on underwater piers Vacation watertight and using it to construct the piers will be. ; The purpose of this invention is a watertight installation is possible without removing the bottom sediments of water Vacation equipped with a watertight plan to reduce costs and ease of pier construction as such, and the air is reduced. ; To this end, the present invention is wedge-shaped or concave panel at the bottom of the slope portion is formed to be inserted into a watertight material features that form a "V" shape. ; In addition, these indications of the assembly to install in the ground in the land of the bed to the construction process and the pier foundation or pier, watertight Vacation interior of the ground tosacheung and remove accumulated in the process to install multiple files and multiple file and to cure leveling pouring concrete on the ground that the construction process, by pressing a Vacation to leveling concrete step of blocking the oesu influx of internal Vacation a step of draining the water, and cut files to the construction of piers and pier foundation based on the installed process and demolish Vacation characterized in that the process to recover the tosacheung around the pier foundation. ; Accordingly, the present invention is formed by a slope installed watertight material into the bottom of the watertight Vacations, prior to the operation to remove the tosacheung of soil is necessary for installation of watertight Vacation improved ease of operation and cost reduction and air doemeun course, overcome the buoyancy of the ground by its own weight and the external pressure of tight and efficient Vacations is kept watertight, the watertight Vacation leveling the ground that the installed concrete pouring curing is improved adhesion and shear stress by the material, concrete piers by protective panels It is the prevention of damage is the useful effect, such as to improve the durability of the structure.
