Description

  The present invention relates to a lining material before reversal in a method in which a lining material impregnated with an adhesive on the inner surface is inserted into a pipeline while inverting the inner and outer surfaces, and the reversed lining material is lined in the pipeline. The present invention relates to an apparatus for impregnating an inner surface of an adhesive with an adhesive.

  Conventionally, as a method for impregnating an inner surface of a lining material with an adhesive in this kind of pipe lining method, a method described in JP-A-10-249940 has been known. In this method, an adhesive is injected into the lining material, the lining material is placed on a conveyor having an inclined portion, the lining material is squeezed while pulling up the inclined portion of the conveyor, and the adhesive is applied to the inner surface of the lining material. Impregnation.

  However, in this method, the lining material is impregnated in advance in the factory, and the inner surface of the lining material impregnated with the adhesive is transported to the construction site to be lined on the pipeline. The inner surface of the lining material cannot be impregnated with an adhesive.

  If an attempt is made to impregnate the inner surface of the lining material with an adhesive at the construction site, a huge conveyor will be transported to the construction site, which is virtually impossible. Further, if the conveyor is downsized, the adhesive is repeatedly injected into the lining material, which takes time and may cause early curing of the adhesive.

  The present invention will be described below with reference to the drawings. FIG. 1 shows the entire impregnation apparatus 1 of the present invention. From the rear part to the front part, two feeding devices 2, two water tank containers 3, an impregnation part container 4 and a reversing machine 5 are arranged. A lining material 6 is inserted through the delivery device 2 to the reversing machine 5.

  As shown in FIG. 2, in the delivery device 2, a reel 8 around which a lining material 6 is wound is rotatably accommodated in a container 7, and the reel 8 is rotationally driven by a motor 9. Then, the lining material 6 fed out from the reel 8 is fed out from the outlet 10 at the front end of the container 7.

  As shown in FIG. 3, the water tank container 3 is provided with a water tank 12 in the container 11, a roller conveyor 13 is provided in the water tank 12, and the lining fed from the outlet 10 of the feeding device 2. The material 6 enters from the inlet 14 at the rear end of the container 11, advances while being supported by the roller conveyor 13 in the water tank 12, and is sent out from the outlet 15 at the front end of the container 11.

  In FIG. 1, two water tank containers 3 are arranged in series, but this water tank container 3 may be single, or three or more water containers can be arranged in series.

  The present invention, as will be described later, injects an adhesive into the lining material 6, impregnates the lining material 6 while moving the lining material 6, and early effects of the adhesive by the cooling water filled in the water tank. Therefore, it is necessary to adjust the viscosity to improve the impregnation property, so that a sufficient length of the adhesive can be injected into the lining material 6.

  On the other hand, the present invention is intended to impregnate the lining material 6 with the adhesive at the lining construction site, so that the aquarium container 3 itself can be mounted on a truck and transported to the construction site. In order to have a length sufficient to inject a sufficient amount of adhesive and to be transported to the construction site, it may be necessary to provide a plurality of water tank containers 3 themselves. It is.

  Thus, in order to provide a plurality of water tank section containers 3, it is necessary to immediately introduce the lining material 6 fed from the outlet 15 of the first water tank section container 3 from the inlet 14 of the next water tank section container 3. As shown in FIG. 1, it is preferable to provide the roller conveyor 16 also between the two water tank containers 3.

  Next, as shown in FIG. 4, the impregnation unit container 4 contains a belt conveyor 18 that is inclined so that the front becomes higher in the container 17, and a squeezing roller 19 is provided at the front upper end of the belt conveyor 18. ing.

  Thus, the lining material 6 sent out from the outlet 15 of the water tank section container 3 enters the container 17 through the inlet 20 at the rear end of the container 17, is placed on the belt conveyor 18, and is conveyed obliquely forward and upward. Excess adhesive is squeezed by the squeezing roller 19 at the front upper end of the conveyor 18, and sent out from the outlet 21 at the front end.

  As shown in FIG. 4, the ceiling 22 of the impregnation unit container 4 is provided such that the front part is pivotably opened upward. When the operator 23 works on the front upper part in the impregnation part container 4, the ceiling 22 is provided. It is preferable to open 22 upward to facilitate work.

  Next, as shown in FIG. 5, the reversing machine 5 rotatably supports a reel 25 around which a lining material 6 having an inner surface impregnated with an adhesive is wound in a pressure vessel 24, and the reel 25 is rotated by a motor 26. The lining material 6 is rotationally driven in the winding direction. The reversing machine 5 is mounted on a truck 27 so that it can be moved away from the impregnation container 4.

  The lining material 6 whose inner surface is impregnated with the adhesive in the impregnation unit container 4 and fed out from the outlet 21 enters the reversing machine 5 through the opening 28 of the reversing machine 5 and is fed to the reel 25 that is rotationally driven by the motor 26. Wrapped and housed.

  Thus, the lining material 6 wound around the reel 8 is unwound from the reel 8, inserted into the water tank container 3 and the impregnation container 4, and an adhesive is injected into the lining material 6. .

  Then, the lining material 6 injected with the adhesive is immersed in the cooling water 31 in the water tank 12 in the water tank container 3, and the adhesive injected into the lining material 6 is cooled by the cooling water 31, Curing is prevented.

  At this time, depending on the length required to inject the adhesive into the lining material 6 in the aquarium container 3, and depending on the size capable of transporting the aquarium container 3, the aquarium container 3 as described above. The number of can be increased or decreased.

  Then, in the impregnation portion container 4, the lining material 6 into which the adhesive has been injected is pulled up obliquely upward, whereby the adhesive in the lining material 6 is returned downward, and a small amount of adhesive is attached to the lining material 6 to allow the belt. It is pulled up by the conveyor 18 and squeezed by the squeezing roller 19 to uniformly impregnate the inner surface of the lining material 6 with the adhesive, and the lining material 6 is drawn into the reversing machine 5 and wound around the reel 25.

  Thus, in order to line the lining material 6 on the pipe line, as shown in FIG. 6, the reversing machine 5 mounted on the track 27 is separated from the impregnation section container 4 and moved to the lining work site. A downward base 29 is attached to the opening 28 of the 5, and the end of the lining material 6 is fixed in an annular shape to the tip of the base 29.

  When a pressure fluid is inserted into the pressure vessel 24 in this state, the fluid pressure is transmitted into the base 29, and the annular fixing portion of the lining material 6 that is annularly fixed to the tip of the base 29 is pressurized, and the annular fixing is performed. The portion is pushed out from the tip of the base 29 to form a reversing portion 30, and the lining material 6 is pushed out while being reversed in the reversing portion 30.

  At this time, since the adhesive impregnated on the inner surface of the lining material 6 is located on the outer surface of the lining material 6, the lining material 6 moves forward while being reversed by the reversing portion 30, and the lining material 6 is passed through the pipe line. The inversion part 30 is inserted from a terminal (not shown), and the lining material 6 is adhered to the inner surface of the pipe line by the adhesive located on the outer surface of the lining material 6 and is lined.

  Therefore, according to the present invention, the entire device is divided into small devices and transported to a construction site lined on a pipeline, and a large device is assembled by combining them, and adhesive is applied to the inner surface of the lining material 6 by the device. The lining material 6 that can be appropriately impregnated and impregnated with the adhesive can be immediately used for the lining of the pipe line.
