is an anchor bolt made of a metal rod of an appropriate length with a male thread cut into the peripheral wall on the distal end side, and the anchor bolt 1 is connected to the reinforcing bar 2 for reinforcing the concrete wall on the proximal end side, Further, the male threaded portion on the distal end side of the anchor bolt 1 is screwed into the proximal end side of a connecting pipe 5 having a male thread carved on the inner circumferential surface, and the connecting pipe 5 is connected to another reinforcing bar 3 spaced apart from and parallel to the reinforcing bar 2. Approximately the middle portion is held by a holder 4 fixed to the
By changing the degree of threading with the anchor bolt 1, expansion and contraction with the anchor bolt 1 can be freely adjusted.

所10が形成される。After constructing the pile-stopping concrete 9 walls, a space for constructing an underground wall is formed by excavating and removing the pond bed 8 at the underground wall construction site surrounded by the walls, and the pile-stopping concrete 9 walls on the side of the space are Since the end face of the piece 7 is exposed, by crushing and removing the piece 7 from the exposed end face side, it is possible to easily remove several headed bolts 6 around the headed pole 16 of the mountain stopper concrete 9 wall using a tool or the like. A recess 10 is formed.

られるのである。Therefore, the headed bolt 6 is removed from the connecting pipe 5 by using the recess 10, and a separator 11 for supporting the formwork is screwed and continuous with the connecting pipe 5, and the separator 11 is used for constructing an underground wall. A concrete formwork panel is installed and supported, and after reinforcing is placed between the panel and the above-mentioned 9-wall concrete wall, concrete is cast and hardened to obtain an underground concrete wall that is integrated with the 9-wall concrete wall. It will be done.

ものとすることがきる。Note that a thin plywood is attached to the outer end surface of the piece 7 with a head bolt 6, and the earth wall surface 8 on the underground wall construction side is attached by using the thin plywood.
a may be covered, and since no earth and sand will adhere to the pile-stopping concrete 9 wall constructed in this state, the separator installation work can be further speeded up when constructing the underground concrete wall afterward, and the pile-stopping concrete 9 can be covered.
The jointing of the underground concrete wall to the wall becomes reliable, and the integration of these mutual walls can be made with high strength and reliability.
また前記ピース7は必らずしも発泡スチロール酸のもの

確認を一層容易化することができる。Furthermore, a string-like object may be attached to the headed bolt 6, and in that case, since the string-like object is pressed against the soil wall surface 8a on the underground wall construction side by the concrete during concrete pouring, the string-like object may be attached to the head bolt 6. The presence of the object makes it easier to confirm the buried position of the connecting pipe 5.

連結させることができる。As explained above, the present invention involves screwing the proximal end of a connecting pipe into the end of an anchor bolt that is integrated with the reinforcing bar for reinforcing concrete walls, and screwing the proximal end into the connecting pipe. A piece that is to be removed after construction of a concrete wall is attached by surrounding the bolt with a head bolt, and the end face of the piece is exposed to the concrete wall surface to be subsequently cast. Although the anchor is buried in the concrete wall in advance, the buried position of the connecting pipe can be easily confirmed by exposing the end face of the piece, which makes it easy to remove the piece after constructing the concrete wall. At the same time, when the piece is removed, a recess is formed around the head bolt of the concrete wall, so the removal operation of the head bolt with tools etc. can be easily performed without any problem. When constructing an underground wall, the separator for supporting concrete formwork can be replaced with the headed bolt, and the separator can be threadedly connected to the connecting pipe quickly and reliably.
