JIG FOR DROPPING SOIL SPATULA AND METHOD FOR DROPPING SOIL SPATULA
To provide a jig for dropping a soil spatula and a method for dropping a soil spatula capable of securing a reaction force at a tip of a spatula with simple equipment and capable of performing work easily and reliably even at a large depth.SOLUTION: A jig for dropping a soil spatula 1 is used which comprises a main body portion 3 having an inclined member 3b connected so as to be inclined to a soil side near a lower end portion 4 of a vertical member 3a, a weight adjustable weight 5 provided on a back surface 25 of the vertical member 3a, a plurality of hanging rings 8 provided at an upper end portion 7 of the vertical member 3a, and a spatula 11 provided at a lower end portion 27 of the inclined member 3b. Then, adjustment of the hanging position by the hanging ring 8 and adjustment of the weight of the weight 5 are performed, horizontal force is secured so that the spatula 11 is pressed against a steel pipe sheet pile 43, a soil spatula 53 surrounded by the steel pipe sheet pile 3 and a steel pipe fitting 49 is dropped. The spatula 11 is attachable to and detachable from the inclined member 3b and exchanged for another spatula 31 according to a planar shape of the steel pipe sheet pile 43 and the steel pipe fitting 49.SELECTED DRAWING: Figure 1
【課題】簡易な設備でへら先端の反力を確保でき、大深度においても容易かつ確実に作業を行うことができる土べら落とし治具および土べら落とし方法を提供すること。【解決手段】鉛直部材３ａの下端部４付近に土べら側に傾斜するように斜め部材３ｂが接続された本体部３と、鉛直部材３ａの背面２５に設けられた重量調整可能な重錘５と、鉛直部材３ａの上端部７に設けられた複数の吊環８と、斜め部材３ｂの下端部２７に設けられたへら１１とからなる土べら落とし治具１を用いる。そして、吊環８による吊り位置の調整および重錘５の重量の調整を行って、へら１１が鋼管矢板４３に押し付けられるように水平力を確保し、鋼管矢板３と鋼管継手４９とで囲まれた部分の土べら５３を落とす。へら１１は、斜め部材３ｂに対して着脱可能であり、鋼管矢板４３と鋼管継手４９の平面形状に応じて他のへら３１に交換される。【選択図】図１
