空洞穴に詰め込んで前記空洞穴を埋めるための空洞穴を
埋め込み方法、及び、その空洞穴の埋め込み体に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for filling a hollow hole formed in the soil by filling and removing a buried pipe to fill the hollow hole, and a method for filling the hollow hole. It relates to an embedded body of the hollow hole.
従来、上記の如き空洞穴を埋め込むには、次の２方法
が知られている。Conventionally, the following two methods are known for embedding the hollow hole as described above.
第１の方法は、ポンプに連結したホースを前記空洞穴
に挿入した後、ポンプによりホースの先端から泥状の土
砂を噴出させながら、ホースを引き抜き側に移動させて
空洞穴に前記土砂を詰め込んでいく方法である。In the first method, after inserting a hose connected to a pump into the hollow hole, the hose is moved to the pulling-out side while the muddy earth and sand is ejected from the end of the hose by the pump, and the hollow sand is filled with the earth and sand. It is a way to go out.
又、第２の方法は、前記空洞穴とほぼ同径の樹脂塊を
順次詰め込んでいく方法である。The second method is a method in which a resin lump having substantially the same diameter as the hollow hole is sequentially packed.
しかし、上述の第１の従来方法によれば、前記ホース
を等速度で移動させることが非常に困難であるため、前
記土砂を空洞穴に均等に詰め込んで行くことができず、
空洞穴を充分に埋め込み難かった。However, according to the above-mentioned first conventional method, it is very difficult to move the hose at a constant speed, so that the earth and sand cannot be evenly packed in the hollow holes,
It was difficult to sufficiently fill the cavity.
一方、上述の第２の従来方法によれば、前記樹脂塊を
空洞穴に充分に充満させるには、その樹脂塊の外径と空

は、樹脂塊を空洞穴に詰め込んでいくこと自体が非常に
困難であるという問題があった。又、径が様々に異なる
空洞穴に合わせて寸法の異なる樹脂塊を多種類製作して
おかなければならないため、実施コストが高くなる欠点
があった。On the other hand, according to the second conventional method described above, in order to sufficiently fill the cavity with the resin mass, the clearance between the outer diameter of the resin mass and the inner diameter of the cavity must be extremely small. However, when the clearance is small, there is a problem that it is very difficult to pack the resin mass into the cavity. Further, since various types of resin blocks having different dimensions must be manufactured in accordance with hollow holes having various diameters, there is a disadvantage that the implementation cost is increased.

洞穴に挿入していく方法とがある。According to the first characteristic configuration of the method of embedding a hollow hole according to the present invention, a filling material formed by mixing an expanding material which expands volume by water absorption into an aggregate is packed in a bag to form an embedding body. Since the embedding body is formed to have a diameter smaller than the diameter of the hollow hole, the embedding body can be easily inserted into the hollow hole, and even if the embedding body is easily bent, the wire rod connected to the distal end portion of the embedding body is used. Since the embedded body is hung on a rod and inserted into the hollow hole while supporting the embedded body so as not to bend, the insertion can be performed easily and reliably. In addition, a specific method of hanging the wire connected to the tip of the embedding body on the tip of the rod and inserting the embedding body into the hollow hole with the support of the rod is as follows. There are a method in which the rod is pulled from the entrance side of the cavity and inserted into the cavity, and a method in which the rod and the embedded body are simultaneously inserted into the cavity.

According to the characteristic configuration described above, in order to pack the filler into the hollow hole, for example, the filler may be ejected from a distal end portion of a hose via a pump as in the above-described conventional technique. Even if the cavity is not packed into the cavity, the cavity can be sufficiently and uniformly buried by the volume expansion of the expanding material.

いることができる。In order to produce the hollow body embedded body (1) shown in FIG. 1, a filler (2) formed by using earth and sand at the site as an aggregate, and mixing the aggregate with an expanding material that expands in volume by absorbing water is used. ,
The volume mixture of the filler (2) to be packed in the bag (3) is preferably about 50 to 500 aggregates with respect to the intumescent material 1. Further, as the material of the bag (3), a material which is easily decomposed in soil is desirable, and for example, a perishable cloth such as cotton or hemp, or a pulp of long fiber whose fibers are separated by moisture can be used. .

の挿入作業を進めていく。As shown in FIG. 1 (a), the embedded body (1) is formed to have a slightly smaller diameter than the inner diameter of the hollow hole (H) so that a clearance is formed between the embedded body (1) and the hollow hole (H). In advance, a steel wire (4) as a wire is connected to the tip. In addition, instead of using the steel wire (4) as the material of the wire, if the same material as the bag (3) is used,
The wire does not retain its shape even if it is not removed. And a forked wire hook (5a) provided at the tip of the rod (5)
And the rod (5) is inserted into the cavity (H) to insert the embedded body (1) into the cavity (H) simultaneously with the rod (5). Since the diameter of the vertical hole is limited, the above-described insertion operation is performed while sequentially adding the rod (5).
空洞穴（Ｈ）に対する埋め込み体（１）の挿入が済む

In order to bury a hollow part (about 7.9 liters) having a diameter of 5 cm and a length of 4 m, for example, a filler (2) obtained by mixing 6 liters of the wet keeper with 5 liters of on-site earth and sand may be used. In such a case, the embedded body (1) in the hollow hole (H)
There is sufficient clearance at the time of insertion to facilitate the insertion operation, and the filler (2) expands to about 8 liters, so that the filler (2) can be sufficiently filled in the hollow hole (H). it can.
