QUAY WALL OR REVETMENT STRUCTURE, AND CONSTRUCTION METHOD OF THE SAME
To provide a quay wall or a revetment structure and a construction method of the same which make a precast member lightweight in transportation and construction, make a whole structure rigid, improve an aseismatic performance, is easily constructed, and is economical.SOLUTION: A quay wall or a revetment structure 1 is formed of a plurality of precast PC slabs 4a stacked on a subsoil 2, in which continuous tendons 12 are disposed in at least two holes 6 per one PC slab from the uppermost portion to a predetermined depth in the subsoil 2. The tendon 12 disposed in the subsoil is formed of an anchor fixing portion 3 and a PC connection portion 5, and a lower end of the tendon 12 is fixed in the subsoil 2 via the PC connection portion 5 by cured grout 13 filled in the anchor fixing portion 3. Prestress is applied to the PC slabs 4 tensely fixed and stacked on the subsoil 2 at the uppermost portion of the PC slab 4, the PC slabs are integrated with each other by PC press-bonding, and perforated PC slabs 4a are used, to make members lightweight in transportation and construction.SELECTED DRAWING: Figure 1
【課題】運搬時及び施工時にプレキャスト部材を軽量化し、構造全体を強固し、耐震性能を向上させると共に、施工が簡単で且つ経済的な岸壁または護岸構造およびその構築方法を提供する。【解決手段】地盤２上に複数のプレキャストＰＣ版４ａを積み上げて形成される岸壁または護岸構造１であって、少なくともＰＣ版一枚当たり２箇所以上の孔６に連続した緊張材１２が最上部から地盤２の所定深さまで配置され、地盤内に配置される緊張材１２は、アンカー定着部３とＰＣ連結部５とで形成され、該緊張材１２の下端がＰＣ連結部５を介してアンカー定着部３に充填されたグラウト１３の硬化によって地盤２内に定着し、ＰＣ版４の最上部において緊張定着され地盤２の上に積み上げてなるＰＣ版４にプレストレスが付与されると共に、ＰＣ版同士がＰＣ圧着接合して一体化され、孔あきＰＣ版４ａを用いることにより、運搬時や架設時に運搬時や架設時に部材の軽量化を図る。【選択図】図１
