物部分を止水する方法に関する。[Detailed description of the invention] Suekan F! A is for creating concrete structures such as walls and beams, where one end is screwed onto an embedded anchor in an existing external wall such as an underground continuous wall, and an expansion layer is interposed between the existing external wall and the existing external wall. The present invention relates to a method for water-stopping a portion of the concrete structure through which a separator for positioning and fixing the formwork to an existing outer wall is inserted.

、シかも止水ｔ−確実なものにしにくいといった欠点が
あった。The conventional method for water-stopping the separator insertion part in this type of concrete structure was to pull out the separator after creating the concrete structure and fill the hole where the separator was pulled out with waterproof mortar or the like. When using this method, instead of requiring one process of extracting the separator and filling with Mortamo, etc., to stop the water, it is possible to fill the hole where the extraction was made from the side opposite to the expansion layer of the concrete structure. Since it is necessary to adopt a difficult working shape, the overall working efficiency is low and there are disadvantages in that it is difficult to ensure a watertight seal.

な特徴を有する本発明の作用は次の通シである。The characteristics of the water stopping method for a separator insertion part in a concrete structure according to the present invention to achieve the above object are as follows:
Concreting of the concrete structure object v is performed with the sealed space around one end side of the separator filled with caulk, and after that, the separator ua is separated from the embedded anchor so that at least one end thereof is This book is characterized in that by extracting the separator to a shape m located in the sealed space, the extraction trace at one end of the separator is backfilled with the filling caulk to stop water. The operation of the invention is as follows.

なえる。Water can be stopped due to the backfilling action of the caulk, so there is no need for special water stopping work, and it is a simple process of removing the separator. The desired water flow can be achieved all at once with just some work.
従って、本発明は、セパレータ押通部の止水を容易に、

た。Therefore, the present invention makes it easy to stop water in the separator penetration part.
Moreover, it was possible to carry out the work very efficiently, and as a result, it was possible to achieve the effect of being able to move on to the subsequent work 1 (in a short period of time).
以下、本発明の実施例を図面に基づいて説明する。Embodiments of the present invention will be described below based on the drawings.
