prestressed walltype pile and manufacturing method thereof and construction method of pile wall structure using the same pile

摘要

Installation up to the upper end portion of the invention is H-beam 10 is pre-given a flex-load placement curing the concrete 45, the tensile part of the H-beam 10, but the two side portions include, but form a groove 43 striking portion 46 to and to produce a flange (41) is concrete 45, a prestressed wall-type file 40 prestress is introduced to the working up a load 30 when not exposed and gradually removing a load without placing the compression section 42 do. And to install bring up across this prestressed wall-type file 40, the wonjiban 1 is a wall-type file 40 exposed installed one after another type of the intended boundary or flange 41 to, install the file wall (50) when subsequently installing prestressed wall-type file 40, a groove 43 with each other to meet formed grouting conducted order grouting 3 to the groove 51 is exposed while the file wall 50 removed gradually digging the ground within the a flange (41) strut (sTRUT), (6) and the wale (wALE) (7) the phase remains stable to install and when the removal of the gravel has been completed the front end connected to the exposed flange 41 re-studs (sTUD the ) 60, or with a base of concrete 4 and the wall of the weld good and underground structures (9) to both end portions to the reinforced with U-shaped cast-in-place curing the concrete (45) to be integral with the shear connector step by step wales 7 and remove the strut (6) Which will open the file wall (50) and a fully synthetic ground structure 9 is installed.; Another embodiment prestressed wall-mounting file body introduces a load to the H-beam 10, and close to the compression unit 72 toryupan installation groove 71 left by being striking portion 46 and the striking portion (46) only in an example ( 40) toryupan to areas other than the predetermined length, the installation of the groove 71 is a prestressed wall-type file (40 of prestress is introduced with concrete (45) cast-in-place curing and when gradually removed upward load (30 loads a) to be installed) is produced and, the prestressed wall-type file 40, the type of the soil and form a file wall 50 by inserting a toryupan 5 to toryupan installation groove 71 to remove the earth and sand within the file wall (50) and while step by step, the installation welding the strut (6) and the wale (7) on the exposed flange (41) to remove the earth and sand completely and U shear connection re-stud 60 or the reinforcement to the exposed flange 41 characters to the form good and a weld end portions of underground formations 9 Based concrete 4 and the prestressed wall-type file 40, while placing curing the concrete (45) shear connector and to be integrated step-by-step strut (6) and the wale (7) remove the files wall 50 and completely synthesized of the installation to the underground structure (9).
