PILE LOADING TEST APPARATUS
PROBLEM TO BE SOLVED: To provide a pile loading test apparatus capable of executing a pile load test even in a narrow and small area using a general anchor pile which has no special shape and does not require to be inserted up to a front-tip support layer.SOLUTION: A pile load test apparatus 10 is constituted of including: an anchor pile 1 which has a diameter larger than that of a test pile 2 and a length longer than that of the test pile 2, and which has cylindrical shape into which the test pile 2 is inserted and does not reach to a bearing layer G2; and a jack 3 which is disposed to the pile head of the anchor pile 1 to push down or pull out the test pile 2 by take a reaction on anchor pile 1.SELECTED DRAWING: Figure 1
【課題】特殊な形状を有していない一般的な反力杭を使用しながら、反力杭を先端支持層まで貫入させることを必要とせず、狭小なエリアでも杭の載荷試験を実施することのできる杭の載荷試験装置を提供すること。【解決手段】試験杭２よりも杭径が大きく、かつ試験杭２よりも杭長が短く、試験杭２が挿入される筒状で支持層Ｇ２まで到達していない反力杭１と、反力杭１の杭頭に配設され、反力杭１に反力を取って試験杭２を押込むもしくは引き抜くジャッキ３と、からなる杭の載荷試験装置１０である。【選択図】図１
