However, in the conventional side wall construction method, the construction accuracy was not good because it was difficult to adjust the formwork while it was being raised. This necessitated rework and repair work on the concrete surface, prolonging the construction period and causing safety issues during construction. Therefore, the reality is that the conventional slipform construction method is not suitable for constructing structures with continuous side walls, such as underground tanks, which require high precision. In other words, the conventional method of constructing side walls using slipforms had problems in terms of construction accuracy, lengthened the construction period due to rework, and caused problems in terms of safety during construction.

In the side wall construction method using the slip form of the present invention, the distance from the underground continuous wall is adjusted using a distance adjustment device so that the guide is vertical, and then concrete is poured between the underground continuous wall and the formwork. The side wall is constructed continuously by operating the jack while setting and raising the formwork. Therefore, the lateral pressure of the concrete is transmitted to the underground continuous wall from the riser and the guide through the distance adjustment device, making it possible to construct the side wall with high precision.

る。 The underground continuous wall 1 is a wall that is continuous underground and serves as a foundation, and side walls are constructed along this underground continuous wall 1. The guide 5 is made of H steel, and the anchor 6, wall connecting member 7, wood bracket 8, fully threaded bolt 9, and nut 10 are used to connect the underground continuous wall 1 and the guide 5.
constitutes a distance adjustment device between the This distance adjusting device has one side in contact with the guide 5 via the roller 13 and the other side attached to the back surface of the formwork 11.

を構築する。次にその手順について説明する。 In constructing the side wall, first, anchors 6 are driven into the previously constructed underground continuous wall 1 at equal intervals, and wall connections 7 are attached. Then, set the guide 5 to the bottom plate 2.
erect it from the beginning and fix it to the wall joint 7. that time,
Use a wooden cone 8, a fully threaded bolt 9, and a nut 10. That is, the distance from the underground continuous wall 1 is adjusted so that the tip of the fully threaded bolt 9 screwed into the wooden concrete 8 passes through the side plate of the guide 5, and the guide 5 becomes vertical. Next, a beam is installed between the underground continuous wall 1 and the guide 5, and a hydraulic jack 3 is placed on the beam.
Attach it and hang Rod 4 from it. Note that although a hydraulic jack is used here, the jack is not limited to this and may be an electric jack. After assembling the formwork 11 and the riser 12 on the bottom plate 2, this is attached to the rod 4. A roller 13 with low frictional resistance is attached to this riser 12, and by bringing this into contact with the guide 5, the riser 12 and the formwork 11 are prevented from shifting. Note that although a roller is used here, it is needless to say that the roller is not limited to this, and a sled-shaped member or the like may be used as long as the frictional resistance can be reduced. After this preparation, actually build the side walls. Next, the procedure will be explained.

築される側壁に固定する。 First, while pouring concrete 14, the rod 4 is pulled up using the hydraulic jack 3, and the formwork 11 is pulled up.
and raise the whole belly-up 12. As it is raised in this way, when the formwork 11 and riser 12 come to a position where the fully threaded bolts 9 stretched between the underground continuous wall 1 and the guide 5 are obstructed, the fully threaded bolts 9 are temporarily removed and the concrete is removed. 14 was poured,
The formwork 11 is raised. When the formwork 11 further rises, the wood concrete 8 appears on the surface of the concrete that has been removed from the lower end of the formwork 11. A full-threaded bolt 9 is screwed into this wooden bracket 8 again, and the tip of the wooden bracket 8 is screwed onto the guide 5 with a nut 10 and tightened to fix the guide 5 to a side wall constructed of poured concrete 14.
このようにしてコンクリート１４の側圧は、型

While preventing the bending of the raised 12 and the displacement of the formwork 11,
You can continue building the side walls.

As is clear from the above description, according to the present invention, it is possible to eliminate rework and repair work on the concrete surface of the side wall due to the poor construction accuracy of the conventional slip form side wall construction method, and to shorten the construction period. Safety inside can be ensured.
In other words, the construction accuracy is improved, and it is possible to construct a highly reliable side wall that is excellent in terms of economy and safety.
