In recent years, interest in basements has increased due to soaring land prices, land overcrowding, sunlight problems, noise problems, energy conservation problems, and other reasons. Traditional basements are generally
The on-site casting method of RC is the mainstream, and in the case of RC construction, in order to make the external wall waterproof, waterproof construction with mortar coating, waterproof sheet, etc. is required on the outside of the RC wall, and there is no need for people to enter for this purpose. Additional excavation was needed so that the work could be done comfortably. However, in recent years, structures have been built to fill the boundaries of neighboring properties, making it impossible to excavate more. In such cases, instead of external waterproofing, a double wall structure using blocks etc. is adopted as internal waterproofing, or before constructing an RC wall, the external frame board of the formwork for concrete pouring is preliminarily attached to the indoor side. There is also a proposal to form a waterproof layer and pour concrete in contact with this layer to make the outer surface of the RC wall waterproof. However, if additional excavation is not possible, the construction is complicated and costly, and the reliability of water-stopping performance is low.

This underground structure has the above-mentioned configuration, and the outer, end, and inner edges of this structure are covered with a waterproof layer, and the joints between panels are the wide flat areas between the waterproof layers from the inside to the inner edges. Since the panels are sealed with joints, there is no risk of water permeating through the panel or penetrating through the gaps between the joints, resulting in excellent water-stopping properties and easy repair and management. In addition, the outer, end, and inner edges of the panels are coated with a waterproof layer in advance, and after being attached to the steel frame of the building, the joints can be pasted from the indoor side to close the joints and provide significant water-stopping properties. There is no need for additional excavation, and underground structures can be constructed easily in narrow spaces. In addition, since we use factory-produced cement-based panels, RC
The construction period is shorter and the construction cost is lower than that of conventional construction, and the water-stopping reliability is also improved.
