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-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

Embodiment Construction

[0163] figure 1 A flow chart showing an example of the construction procedure when using the steel sheet pile as the jointed steel material and the temporary steel material as the first invention of the present invention is carried out in the following order.

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

[0165] In at least one place, drive temporary sheet piles ( figure 1 b), forming an area enclosed by part of the sheet pile wall and temporary sheet piles ( figure 1 c).

[0166] Excavating to remove sand and soil in enclosed areas ( figure 1 After d), clean the joints of the steel sheet pile walls in the area ( figure 1 e).

[0167] Then, install automatic welding machines in the area ( figure 1 f), for automatic welding ( figure 1 g).

[0168] After confirming that ...

Abstract

The present invention relates to a steel plate wall and a manufacturing method thereof. The steel plate wall is formed by connecting a plurality of steel materials having joints at both ends with the above-mentioned joints, wherein: the joints are covered with steel water-proof sections, and the joints are covered along the length Continuous welding between the above-mentioned water-proof section bar and the above-mentioned steel material, and / or between the water-proof section bar and the water-proof section bar without gaps. Such welding can be performed by automatic welding or the like by ensuring a weldable space by removing sand and moisture 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 ...
