Abstract

PURPOSE:To provide a method for repairing a conduit in which a conduit of a large bore or a noncircular section or a conduit for receiving a large hydrostatic or external pressure can be easily lined at a low cost. CONSTITUTION:A method for repairing a conduit comprises the steps of inverting and inserting tubular nonwoven fabric 2 covered on an outer periphery with a film 3 having high sealability into the conduit 1 by hydraulic pressure, then inserting a tubular lining material 4 into the fabric 2, operating hydraulic pressure into the material 4 to cure curable resin impregnated in the material 4 while pressing the material 4 and the fabric 2 to the inner periphery of the conduit 1. Since the fabric 2 is interposed between the conduit 1 and the material 4, even in the case of the conduit 1 having a large bore, the material 4 having a thinner thickness than prior art can be used. Further, since the fabric 2 and the material 4 are separately inserted into the conduit 1, the conduit 1 can be easily lined at a low cost.

2. Description of the Related Art When a pipeline such as a sewer pipe buried in the ground is deteriorated, a pipeline repairing method for repairing the pipeline by lining the inner peripheral surface of the pipeline without excavating the pipeline. Has already been proposed and put to practical use (for example, JP-A-60
No. 242038). That is, this pipe repairing method is, for example, inserting a flexible pipe lining material impregnated with a thermosetting resin while reversing the pipe by hydraulic pressure, and pressing it against the inner peripheral surface of the pipe, , The pipe lining material is heated by steam or the like to make hot water, and the thermosetting resin impregnated in the pipe lining material is hardened by the hot water to cure the inner peripheral surface of the pipe line. It is a method of lining with wood. Various other pipeline repair methods have been proposed (Japanese Patent Publication No. 55).

In order to achieve the above object, the method of the present invention is designed so that a tubular non-woven fabric whose outer peripheral surface is covered with a film having high airtightness is inverted and inserted into a duct by fluid pressure, A tube lining material obtained by impregnating a resin absorbent with a curable resin is inserted into the tubular non-woven fabric, and a fluid pressure is applied to the inside of the tube lining material to press the pipe lining material and the tubular non-woven fabric against the inner peripheral surface of the duct. It is characterized in that the curable resin impregnated in the pipe lining material is cured as it is.

According to the present invention, since the tubular non-woven fabric is interposed between the pipe line and the pipe lining, the substantial lining thickness for the pipe line is a value obtained by adding the thickness of the tubular non-woven fabric to the thickness of the pipe lining material. For the lining of large-diameter pipes, it is possible to use pipe lining materials that are thinner than before, and since the tubular non-woven fabric and the pipe lining material are inserted into the pipes separately, the pipes of large diameter The lining can be performed at a low cost with good workability even for a pipe having a non-circular cross section.

Further, for example, in a pipe line which is buried under a road and receives a large external pressure, the tubular non-woven fabric interposed between the pipe line and the pipe lining material serves as a cushioning material to absorb and relax external pressure (particularly, live load). Therefore, the thickness of the pipe lining material may be thinner than the conventional one, and the construction can be performed easily and inexpensively.

Further, in a pipeline that receives a large water pressure, groundwater accumulated between the pipeline and the pipe lining material flows through a tubular non-woven fabric having good water permeability, and is discharged into the pipeline from a hole or the like formed in the pipe lining material. As a result, the water pressure acting on the pipeline is reduced, and the same effect as described above can be obtained. In addition, since the tubular non-woven fabric blocks the passage of sediment contained in groundwater, the outflow of sediment around the pipeline can be prevented.

In addition, if a tubular non-woven fabric having a small elongation is used, the tubular non-woven fabric can be made to function as a mold for a pipe lining material, and can be easily applied to corrugated pipes having irregularities on the inner surface or pipe lines having defective portions. The lining can be installed on.
