Steel wall manufacturing method

Abstract

The invention provides a method for manufacturing a steel wall by connecting a plurality of steel elements with joints at two terminals with each other, wherein: embedding joints of the steel elements with each other while punching, forming a dual-wall structure steel wall with a close space at the internal side, then removing sand and / or water in the close space, welding the joints of the steel wall automatically. Thereby, comparing with manual welding, the evenness of welding is confirmed by setting the welding process to be automatic welding, requiring no special device and technique used in underwater welding since sand and / or water in the close space is removed, besides no requirement for large working area.

Description

[0001] This application is a divisional application, the application number of its parent application: 200310113838.3, the application date: 2003.10.31, the name of the invention: steel plate wall and its manufacturing method technical field [0002] The invention relates to a method for manufacturing a steel plate wall suitable for places requiring water isolation, such as waste disposal sites, underground walls of buildings, and road retaining walls. Background technique [0003] Steel sheet piles are often used for retaining walls in the construction of underground structures and temporary embankments in the construction of harbor and water facilities. The reason is that the high-rigidity wall made of steel, a high-quality material, not only can be built in a short construction period, but also has relatively good water-proof performance. [0004] Of course, the steel material itself of the steel sheet pile main body does not pass water at all, but in the fitted state, si...

[0015] In addition, in the invention described in Japanese Laid-Open Patent Publication No. 07-324329 (Patent Document 2), the joint is welded, but it is different from that for discarded water because it is water-proof for buildings, that is, water-proof for groundwater in the foundation. For the water-proofing of waste disposal sites, etc., the degree of water-proofing property only needs to match the degree of drainage facilities installed on the side of buildings, which is not the same as the purpose of the present invention is to seek higher water-proofing property and reliable function.

[0016] In addition, in the invention described in Japanese Laid-Open Patent Publication No. 07-324329 (Patent Document 2), since the female joint material 73 with a special shape is used, it is worried that the female joint material 73 will be deformed when driving in, and it is suspected that the groundwater in the excavated foundation The reliability of the vertical welding of the exposed joints in the wet state or in the water state, in addition, the above method cannot be used with automatic welding machines
