GROUND PENETRATION STRUCTURE
To provide a ground penetration structure which can secure water-shielding property at an interface between a water-shielding layer and the ground penetration structure when being used in a control type waste disposal site, and can also increase drawing resistance thereof depending on property of constructed ground and a support object.SOLUTION: On the surface of a foundation support pile 1 that is a ground penetration structure, an uneven part 2 in which shear friction resistance from the ground in a pull-out direction is larger in a penetration direction is formed at least within a range in which the foundation support pile is penetrated into the soil. Thereby, when the foundation support pile 1 is used in a control type waste disposal site, water-shielding property at an interface between the water-shielding layer and the foundation support pile can be secured, and pull-out resistance thereof can be increased.SELECTED DRAWING: Figure 2
【課題】管理型廃棄物処分場内で使用される場合には、遮水層との界面における遮水性を確保することができ、しかも、施工する地盤性状や支持対象物の如何によってはその引抜抵抗を増加させることができる地盤貫入構造体を提供する。【解決手段】本地盤貫入構造体である基礎支持杭１は、その表面で、少なくとも土中に貫入される範囲に、引き抜き方向に対する地盤からのせん断摩擦抵抗が貫入方向に対して大きくなる凹凸部２が形成されている。これにより、本基礎支持杭１が管理型廃棄物処分場内で使用される場合には、遮水層との界面における遮水性を確保することができ、しかも、その引抜抵抗を増加させることができる。【選択図】図２
