る。(Prior Art) Sewage pipes such as fume pipes may be deteriorated due to the influence of corrosive gas, earth pressure, etc., and may cause cracks, water leakage, and the like. For this reason, an aged sewer pipe is rehabilitated by installing an insertion pipe, such as a synthetic resin spiral pipe, inside the sewer pipe. The diameter of the insertion pipe installed in the sewer pipe is selected according to the degree of aging of the sewer pipe, the amount of sewage, and the like, and in the severely deteriorated sewer pipe, a relatively small diameter insertion pipe is used for the sewer pipe. In this case, the gap between the inner pipe and the sewer pipe is filled with a backing agent such as air mortar to reinforce the sewer pipe. However, if the difference in diameter between the sewer pipe and the intubation tube becomes large, the posture of the intubation tube with respect to the sewer pipe may change significantly. In extreme cases, the downstream side of the insertion tube is located above the upstream side, and sewage cannot flow.
This is because buoyancy acts on the inner tube due to the filled backing agent,
This is because the posture of the intubation tube with respect to the sewer pipe changes. If the pressure of the backing agent or the buoyancy of the backing agent due to the backing agent increases, the backing agent may be crushed and damaged.

Lock on. When the end of the wire 4 is locked to the support member 51, for example, a fixture 511 is used. The fixture 511 includes an outer cylinder having a tapered inner peripheral surface and a wedge-shaped inner cylinder into which the end portion of the wire is fitted and which is fitted into the outer cylinder. The inner cylinder is reduced in diameter by pushing the inner cylinder into the outer cylinder to clamp the end of the wire (brand name "PC
Steel wire embedding grip "manufactured by Sumitomo Electric Industries, Ltd.) is used. The other end of the wire 4 is locked to the turnbuckle 6, and the turnbuckle 6 is locked to the support member 52. Then, by rotating the turnbuckle 6, tension is applied to the wire rod 4, and the wire rod 4 is fixed in a state where the insertion tube 2 is locked to the wire rod 4.

内挿管２内には下水が通流される。When the insertion tube 2 is fixed by the wire rods 4, 4, ... In a predetermined posture, a backing agent such as cement milk or air mortar is injected into the gap between the insertion tube 2 and the sheath tube 1. It is preferable to inject the backing agent three times or so when the specific gravity of the insertion tube 2 is relatively light and a large buoyancy force is exerted on the insertion tube 2 by the injection of the backing agent. When the backing agent is injected three times, as shown in FIG. 3, first, the backing agent is injected so that the lower part of the insertion tube 2 is substantially immersed in the backing agent (see FIG. 3). After the solidification of the backing agent, the backing agent is injected so that the portion other than the upper part of the insertion tube 2 is immersed (see FIG. 3B). In this case, the buoyancy acting on the insertion tube 2 is supported by each wire 4 which is locked to the lower portion of the inner peripheral surface of the insertion tube 2. After the injected backing agent is solidified, the backing agent is injected and solidified so that the entire gap between the insertion tube 2 and the sheath tube 1 is filled (see FIG. 3 (c)). ). After the backing material is solidified, the wire members 4 are removed from the support members 51 and 52, and the support members 51 and 52 are removed. As a result, the endotracheal tube 2 is wrapped with the backing agent in a predetermined posture with respect to the sheath tube 1. In this state,
Sewage flows through the inner tube 2.

Good.

れる裏込剤を冷却して，ヒビ割れの発生しない低い温度
条件下で該裏込剤を養生硬化させることができる。If the backing agent is not filled in three times but is performed at one time, a large buoyancy will be exerted on the insertion tube 2. For this reason, there is a possibility that the buoyancy acting on the insertion tube 2 cannot be supported by each wire 4. In such a case, as shown in FIG. 4, the end portion on the downstream side of the insertion tube 2 is made watertight with the water stopcock 61 while the insertion tube 2 is locked to each wire 4. After sealing and injecting water into the insertion tube 2, the upstream end is also sealed in a watertight manner by the water stop plug 62. By doing so, even if the backfill agent is filled in the gap between the insertion tube 2 and the sheath tube 1 at a time, the buoyancy acting on the insertion tube 2 is suppressed by the water stored in the insertion tube 2. Since the insertion tube 2 is inserted, there is no risk of buoyancy in the insertion tube 2, and there is no risk of the insertion tube 2 being squashed. In this case, if the backing agent is filled, there is a possibility that the insertion tube may be more easily deformed due to its heat generation effect.
The water stored in the insertion tube 2 prevents the insertion tube 2 from softening, and further cools the backing agent filled in the gap between the insertion tube 2 and the sheath tube 1 to cause cracking. The backing agent can be cured under low temperature conditions.

る。When water is filled in the insertion tube 2, for example, the upper end of each end is left open without sealing each end of the insertion tube 2, and the upper end of the upstream end is opened. Therefore, the sewage accumulated upstream of the sheath pipe 1 during construction may be fed into the inner pipe 2 by a pump or the like. In this case, the intubation 2
The sent sewage is stored in the pipe, but if the stored amount of the sewage becomes a predetermined amount or more, the sewage stored in the insertion pipe 2 from the open upper end of the downstream end of the insertion pipe 2. Overflows. Therefore, this method is effective when the sewage flowing in the sheath pipe 1 cannot be retained for a long time.

に起因する問題点を生じることがない。(Effects of the Invention) As described above, the method of fixing the insertion tube to the sheath tube according to the present invention has a relatively large difference in diameter from the sheath tube, and a plurality of wire rods are provided on the inner peripheral surface of the insertion tube arranged in the sheath tube. By locking and then tensioning these wire rods, the insertion tube is placed in a predetermined position with respect to the sheath tube, and the backing agent is inserted into the gap between the insertion tube and the sheath tube from the bottom of the sheath tube. Since the method of filling the upper part multiple times is adopted, there will be no problems caused by a relatively large difference in diameter with the sheath tube.

奏する。That is, as described above, when the backing agent is sequentially filled from the lower part to the upper part of the sheath tube in plural times, the buoyancy acting on the insertion tube by the backing agent is filled into the gap at once. It can be significantly reduced compared to the case. Moreover, for example, supposing the case where the lower part of the gap is filled with the backing agent, at this time, the insertion tube is supported by the wire rod that is locked to the lower part of the inner peripheral surface. Therefore, the buoyancy is offset by the supporting force of the wire. Therefore, according to the method of the present invention, the posture of the endotracheal tube is not largely changed by buoyancy, so that it is possible to surely solve the problems such as the inability to flow sewage and the crushing of the endotracheal tube. Produce the effect.

た効果を奏する。Another method of the present invention employs a method of filling the gap between the insertion tube and the sheath tube with a backing agent in a state where the liquid is stored in the insertion tube. The buoyancy acting on intubation can be reduced. Therefore, similarly, since the posture of the endotracheal tube does not change significantly due to buoyancy,
It has an excellent effect that problems such as sewage flow becoming impossible and the intubation tube being crushed can be reliably solved.
加えて，この方法によれば，裏込剤の充填作業を一度に
行えるので，その分，内挿管の固定作業をより一層効率
よく行える，といった効果を奏する。In addition, according to this method, the work of filling the backing agent can be performed at one time, so that there is an effect that the work of fixing the insertion tube can be performed more efficiently.
