Problems solved by technology

[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

Embodiment Construction

[0163] Fig. 1 shows a flow chart of an example of the construction procedure when using steel sheet piles as steel materials with joints and temporary steel materials as the first invention of the present invention, and work is performed in this order below.

[0164] According to the construction capacity of the steel sheet pile driving machine and the number of machines used, the construction of the steel sheet pile wall starts from any part of the water-resistant steel sheet wall (Fig. 1a).

[0165] In at least one place, temporary sheet piles are driven in (Fig. 1b) to create an area enclosed by a part of the sheet pile wall and the temporary sheet piles (Fig. 1c).

[0166] After excavating to remove sand and soil in the enclosed area (Fig. 1d), the joints of the steel sheet pile walls in the area were cleaned (Fig. 1e).

[0167] Then, install an automatic welding machine (Figure 1f) in the area for automatic welding (Figure 1g).

[0168] After confirming that the water is...

Abstract

The invention relates to a steel wall and a manufacturing method thereof. The steel sheet wall is constructed by connecting plural steel sheets with joints on both ends by the joints, wherein, the sectional steels for cutting off water cover the joints to weld the sectional steels for cutting off water and the steel sheets, and/or between the sectional steels for cutting off water along a length direction in a continuously gapless welding manner. Thereby, the weldable space can be ensured and the welding can be performed by automatic welding, etc, through removing sand and water near the welding position.

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 steel plate wall suitable for places requiring water isolation, such as waste disposal sites, underground walls of buildings, and road retaining walls, and a manufacturing method thereof. 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 ...
