この横穴は直径が小さい場合はそのままにしておくか、
ある程度大きい場合には念のためダミーパイプを挿入し
たり、穴内に砂等を詰め込んだりして復旧している。[Prior Art] When a horizontal hole with a small diameter, for example, a diameter of about 35 m / m was excavated using an auger for piping in the ground, it became unnecessary or when pipes or cable ducts were pulled out from the ground. ,
If this side hole has a small diameter, leave it as it is,
If it is large to some extent, just in case, a dummy pipe is inserted or sand is packed in the hole to recover.
［従来技術の問題点］ このため、次のような問題がある。[Problems of Prior Art] Therefore, there are the following problems.
ａ．直径が小さい穴であってもそのままにしておくと地
盤沈下や地下水の通り道となるので好ましくない。a. Even if the hole has a small diameter, it is not preferable to leave it as it is because it becomes a passage for ground subsidence and groundwater.
ｂ．ダミーパイプ等を挿入しておくと、後でこの場所を
掘削したりする際にダミーパイプが障害となる。b. If a dummy pipe or the like is inserted, the dummy pipe will become an obstacle when excavating this place later.
ｃ．穴内に砂等を詰め込むようにするとこの作業に手間
がかかる。c. This work is troublesome if sand or the like is packed in the holes.
本考案は、上記ａ〜ｃに記した問題点の解決を図るため
の手段を提案するのが目的である。The object of the present invention is to propose means for solving the problems described in ac.
［問題点を解決するための手段］ 本考案は、上記問題点を解決する手段として、 紙管内に砂又は砂の割合の大きいモルタルを充填すると

る地中穴充填材を提案する。[Means for Solving Problems] As a means for solving the above problems, the present invention fills a paper tube with sand or mortar having a large proportion of sand, and at both ends of the paper tube at one end side thereof. Proposes a ground hole filling material in which a fitting recess formed of mortar having general strength is formed, and a fitting projection having a size that fits into the fitting recess is formed on the other end side.

手で押し込んだり、機械を利用して穴内に押し込んでし
まうものである。[Operation] As the filling material, one having a diameter close to that of the target hole is selected. When the holes are filled, the fitting recesses and the fitting projections at both ends are used to push them one by one while adding them one by one, or they are pushed into the holes using a machine.

割合いで調整されたモルタル３が充填されていると共に
一端には一般的な強度を有するモルタルで作られた嵌合
凹部４が、他端には嵌合凸部５が形成されている。[Examples] Figs. 1 and 2 show a filler according to the present invention. The filler 1 is a mortar 3 in which a sand: cement is adjusted in a ratio of 9: 1 in a cylindrical paper tube 2. And a fitting concave portion 4 made of mortar having general strength is formed at one end and a fitting convex portion 5 is formed at the other end.
なお、モルタル３は、紙筒２の強度が使用に耐え得る曲
げ或いは圧縮強度を有する場合には砂だけでもよいが、
ある程度の強度をつけるためには少量のセメントを混ぜ
てモルタル状とするのが望ましい。Note that the mortar 3 may be only sand if the strength of the paper tube 2 has bending or compressive strength that can withstand use.
In order to obtain a certain level of strength, it is desirable to mix a small amount of cement to form a mortar.

し、可能な場合には手で挿入してもよい。As shown in FIG. 3, the filling material 1 is inserted into the lateral hole a excavated in the ground by fitting the fitting concave portion 4 and the fitting convex portion 5 to each other for integration, In the case of the embodiment, the filling material 1 is applied to the chuck c of the horizontal hole boring machine b.
Is inserted into the lateral hole a while being chucked. However, if possible, it may be inserted by hand.
充填材１は充填されたのち、横穴ａ内においてこの横穴
ａを閉塞し、土圧等に対抗する。After the filling material 1 is filled, the lateral hole a is closed in the lateral hole a to counteract earth pressure or the like.
［本考案の効果］ 本考案は以上のように、紙筒内に砂又は絶対的に砂の量

穴内に機械或いは手で挿入するようにしたので、次の如
き効果を期待できる。[Effect of the present invention] As described above, the present invention fills a paper cylinder with sand or mortar in an absolutely large amount of sand to form a filler, and inserts it into a hole by a machine or by hand. Since this is done, the following effects can be expected.
ａ．不要となった穴を完全に閉塞することができ、特に
小径の穴の場合に簡単に挿入して閉塞ができる。a. Unnecessary holes can be completely closed, and especially in the case of small diameter holes, they can be easily inserted and closed.
この結果、地盤沈下や水の通り道となる心配がない。As a result, there is no risk of land subsidence or passage of water.
ｂ．充填材は紙と砂を主体としているので、後でこの部
分を掘削する際に障害物とならない。b. Since the filler is mainly paper and sand, it does not become an obstacle when excavating this part later.
ｃ．充填材は穴内に挿し込むだけでよいので、機械或い
は手で小径の穴の場合でも内深部まで完全に挿入し、閉
塞することができる。c. Since the filling material only needs to be inserted into the hole, it is possible to completely insert and close the inner deep portion even in the case of a small diameter hole by machine or by hand.
