い。2. Description of the Related Art This kind of backfilling method for pipe lining is already known, but backing up grout or the like by a simple method has not yet been developed. Incidentally, the prior art takes a measure to form a hole from the inside of the liner at a fine pitch mainly in the upper part of the liner closely wound around the pipe, and to inject grout or the like through the hole. It is difficult to perform this in a place where space is limited, such as in a pipe liner, workability is very poor, and a defect is often caused.

Are installed in parallel. The spacer S is a perforated plate 2 as shown in FIGS.
1, or a similar perforated plate 2-2 as shown in FIGS. Also, a spacer having a curved frame structure can be used. As the spacer S installed in the invert area, a spacer with the vertical rib 3-1 and the horizontal rib 4-1 can be used. As the spacer S installed in the heavenly area, a spacer with the vertical rib 3-2 can be used, and in some cases, a spacer without such a rib may be used. The spacer S may be attached to the ceiling area and the side area by an appropriate method.

, A liner L is formed by spirally winding the strip 1 having the ribs 11 on the back surface (FIGS. 5, 6, 7, and 8).
8). The application of the liner L by this is the same as the conventional method, and the adjacent winding side edges of the strip 1 are joined by the joining strip 10 spirally wound between the side edges. The strip 10 is connected to the joining ears 12 of the strip 1,
12 has a cross-sectional shape that meshes with it.

の介在で空隙Ｃができる。The liner L is attached to the pipe P from above the spacer S.
Is installed, the spacer S is placed between the pipe P and the liner L.
The void C is formed by the interposition of.

流動を許す。従って、この空隙Ｃを通じ裏込め材をライ
ナーＬ背面に注入でき、所要の裏込めが得られる。Since the spacer S has an opening 20 as a whole, the space C formed between the pipe P and the liner L with the spacer S interposed therebetween allows the backfill material such as grout to flow over the entire area. . Therefore, the backfill material can be injected into the back surface of the liner L through the space C, and required backfill can be obtained.

度に広範囲の裏込めを達成することをもたらす。The spacer S has a curved shape. Therefore, the openings 20 are dispersed not only in the pipe length direction but also in the radial direction of the back space C of the liner L, so that the backfill material can be spread well throughout the space C. Therefore, it is possible to achieve a wide range of backfill at once without producing defects.

ライナーに穴あけ等の二次加工は不要である。The backfill material may be injected directly from the end face of the gap C or through a hose H inserted into the gap C. In any case, the backfill material can be easily injected by an extra-tube operation. In addition, the gap C
Can be used for the inflow channel to inject backfill material.
Secondary processing such as drilling in the liner is not required.

リップ１の巻立てに支障を伴わない。In the present invention, a specific type of spacer S is provided on the inner surface of the pipe P to embody the flow path of the backfill material to the back of the liner. This does not hinder the winding of the strip 1.

注入するとよい。When the pipe P has a relatively small diameter and the backfilling is performed in a short span, the liner L is hardly crushed by the pressure even if the backfilling is performed in the entire cross-section. Good to do. In this case, it is preferable to dispose the spacer S in the invert region of the pipe P and inject the backfill material from the end face of the gap C.

域に設置するとよい。If the pipe P has a relatively large diameter, the liner L may be crushed by the pressure when the backfill material is injected into the entire cross section at one time. It is preferable to inject the upper half after curing. In that case, the spacer S may be installed in the ceiling area of the pipe P.

In such a case, the hose H is inserted into the gap C, the injection is performed from the back of the gap C, and the hose is moved while moving the hose to the opposite side.

行い得る効果を奏する。As is apparent from the above description, the present invention can be applied to the backing of a pipe lining of the type described at the outset without hindering the winding of the strip which is a constituent material of the liner. This eliminates the need for secondary processing such as drilling in the liner and does not cause any defective portion, and also provides an effect that a wide range of backfill can be easily performed at once.
