2. Description of the Related Art A conventional underground continuous wall working method involves digging a deep groove around a ground area of a foundation of a site to be erected first, and a pre-assembled rebar cage (or integrally molded) in the deep groove. PC (Precast Concrete,
Put the pre-formed concrete plate), pour concrete (or pour mixed reinforcing agent into both sides of PC board, and after hardening, form a wall integrally with PC board) from above. Form one unit wall of the continuous wall. However, the conventional method of forming a continuous wall has the following disadvantages.

(1) In the configuration, a plurality of stepped walls formed as described above are successively installed and connected to form a continuous wall. Therefore, there is no good mutual connection between the two unit walls, the connection is not tight, and the water tightness and strength required of all the continuous walls cannot be fulfilled.

(2) There is a gap between the two unit walls constituting the unit because they are not tightly connected, and this gap naturally becomes a guide port into which water seeps. Therefore, the continuous wall is infiltrated with water, which poses a danger in construction and annoying that the wall may leak when used later.

(3) In the method of pouring concrete after placing a reinforcing steel basket in a deep groove, since a pouring hole is left in the reinforcing steel cage in advance, concrete is poured from the pouring hole and the unit wall is strengthened. Is formed. However, because the groove is deep and the width is narrow (usually 10 meters or more)
In addition, the reinforced basket affects the binding force due to the contamination of the stabilizing liquid, and the deep dirt wall soil, mud and sand are easily mixed into the concrete, and the strength of the concrete is weakened. A decrease occurs.

(4) After the PC board is inserted into the deep groove, the mixed and prepared hardener is poured into the deep groove to cover both sides of the PC board and form a wall together after hardening. A good connection mechanism between the PC boards Does not exist and merely depends on the curing agent. Therefore, when mixing and preparing the curing agent liquid, there is a change in quality due to an error in the proportion and time of the material, which has a bad effect on the whole.

(5) A traditional underground wall is formed by digging a deep groove, placing a reinforcing steel basket, and then pouring concrete into the work, but the condition of the ground is always poor, and the construction management Is not good, its vertical accuracy, the degree of smoothness of the concrete wall, and the lack of thickness of the reinforcing steel protection layer, etc., easily cause cracks in the wall, and the reinforcing steel will rust and corrode, making it useful as an earth wall. In addition to harm, construction work will be increased.

(6) The work is performed by filling the deep groove with the stabilizing solution. However, since the rebar or the PC board has an extremely large volume integrally formed, it is difficult to perform the work and it is difficult to secure the quality of the wall. For that purpose, it is often necessary to form another wall inside the wall in the groove to decorate the continuous underground wall that is rough or cracked, reducing the space of the basement and repeatedly It is not economical because it requires reinforcement work and increases costs such as manpower, construction time and material operation.
