On-site manufacturing underground indentation method and underground structure formation method

摘要

It relates to a field-produced underground press-fit method and an underground structure forming method using the same, After transporting a number of steel plates cut in a predetermined width and length according to the site conditions to the site, the underground press assembly was manufactured so that horizontal blades were integrally formed on both sides of the rectangular work area and the rectangular work area directly at the site. By adopting a method of forming an underground structure in a special way in the underground using this, Since it is to cut a number of steel plates in a predetermined width and length according to the site conditions and transport them to the site, the volume can be minimized and a large amount can be transported at once, so transport is easy and transport costs can be drastically reduced. After transporting to the site, the underground press unit is manufactured so that the horizontal blades are integrally formed at the upper and lower sides of the rectangular work area and the rectangular work area directly in a large space of the site, so the production of the underground press unit is very easy and the manufacturing time is dramatically reduced. Of course, The vertical gap width of the underground press unit can be accurately manufactured as the thickness of the slab formation, so when the manufactured underground press unit is pressed into the ground, the slab forming space is naturally formed. Slabs can be formed with a simpler, quicker and more accurate thickness than using the method of securing the slab formation space by using the underground press fittings, reducing the number of underground press fittings, and forming a structurally strong underground structure. Material can be drastically reduced and at the same time there is no waste of materials. The waterproofing is accomplished perfectly by welding the ends of the upper horizontal blades of the post-propelled underground press unit to each other or by welding the ends of the upper horizontal blades of the post-propelled sub-ground press unit to the square tube. Therefore, the present invention is not only impossible because there are obstacles that cannot be transferred, such as buildings, roads, and railroads, and it is particularly a low-topic section, so even when the existing construction method cannot install the underground structure in a predetermined form, It is safe, structurally safe, and has the characteristics of quickly and safely constructing a perfect underground structure even waterproof.
