ーに関するものである。DETAILED DESCRIPTION OF THE INVENTION (Technical field to which the invention belongs) The present invention relates to an anchor to be attached to the tip of a drain material such as drain paper when it is driven into the ground.

照）。(Problems of the invention and their characteristic points) An anchor for a drain material having an inverted T-shape and having a lower end portion of the drain material attached to its vertical portion has been conventionally known (Japanese Utility Model Publication No. 60-27137 and Japanese Utility Model Publication No. Sho. 61-15326 publication).

業がかなり面倒である。Such an inverted T-shaped anchor is advantageous in that the vertical portion can be inserted into the lower end opening of the drain material placing mandrel to prevent the horizontal portion from shifting. However, the conventional example is made of plastic. Therefore, it is easily deformed and its strength is weak.Also, the lower end of the drain material is tacked to one side of the vertical part of the anchor, or the vertical part of the anchor material is doubled and the lower end of the drain material is inserted between them. Since the part is inserted and stopped, the work of attaching the drain material is quite troublesome.

ことを目的としているものであって、その構成上の特徴
は実用新案登録請求の範囲に記載したとおりである。The present invention is intended to provide an inverted T-shaped anchor that is durable, easy to manufacture, and extremely easy to attach a drain material, and the structural features thereof are the utility model registration request. As described in the range.

行うことがてきる。The anchor of the present invention can be made by welding two iron plates or by bending one iron plate. Then, the drain material can be attached by folding back the lower end portion of the drain material in advance and inserting the folding portion into the long hole from the side.

る。(Description by Drawings) In FIG. 1 showing an embodiment of the present invention, an anchor 1 is formed by welding two iron plates in an inverted T shape, and a vertical hole 2 has a long hole 3 formed therein. The long hole 3 has an opening 8 on one side.

がりすることがない。When the drain material is driven by using the anchor 1, the lower end portion of the drain material 5 pulled out from the mandrel 4 is folded back on the ground and the overlapping portion is stopped by the stapler 6, and the folded portion is passed through the opening 8 to form a long hole. After putting the mandrel 4 into the mandrel 3, the vertical part 2 is pulled into the mandrel 4, the mandrel 4 is driven into the ground in this state, and the mandrel 4 may be pulled out when the lower end of the mandrel 4 reaches a predetermined depth. Since 1 stops at that position due to the resistance of the soil acting on the horizontal portion 7, the anchor 1 does not rise together with the mandrel 4.

Moreover, it is easy to manufacture, it is economical, and the folded portion formed in advance at the lower end portion of the drain member can be put into the long hole from the side, so that the drain member can be attached very easily. Can be expected.
