Claims

[Claims for Utility Model Registration] (1) A support cylinder 6 consisting of a lower vertical pipe 3, an upper cylinder body 4 with a larger diameter than the lower vertical pipe 3, and an intermediate step plate 5 penetrates the bottom plate 2 of the underground structure 1. A support plate 8 is fixed to the upper end of the vertical tube 7 which is embedded and fixed in the lower vertical tube 3 and arranged concentrically within the lower vertical tube 3, and a seal ring 9 made of an elastic material is attached to the lower end of the vertical tube 7. The closing plate 10 and the support plate 8 are connected to each other by a tightening bolt 11, and the upper cylinder body 4 has locking protrusions 12 on both sides in the diametrical direction. is fixed, a closing plate 14 is placed on the intermediate stage plate 5 via an elastic packing 13, and a tightening member 16 having wedge surfaces 15 inclined in opposite directions at the upper part of both ends is attached to the closing plate 14. The opening/closing device for investigation and grouting of underground structures is placed on the ground, and the wedge surfaces 15 at both ends of the tightening member 16 are pressed against the lower part of the locking protrusion 12. (2) An outer horizontal pipe 34 is installed on the side wall 33 of the underground structure 1.
A support cylinder 6 consisting of an inner cylinder body 35 having a larger diameter than that and an intermediate stage plate 5 is embedded and fixed in a penetrating state,
