Description

The tube reverser apparatus with expension joint

The present invention. One of the parts used in sewage pipe non-digging repair equipment

When connecting the rotating inverting device of the loading box and the inverting box, the present invention relates to an inverting device for attaching and detaching water and sewage, which has elastic joints that can be connected even with slight errors.

A connection angle variable joint is a device that can be rotated around a hinge axis so that a plurality of, for example, two pipes are connected to each other, so that the connected fitting angle of the two connected pipes can be changed.

It is generally composed of two pipe connecting members connected by a hinge axis, and each pipe connecting member is constituted by connecting a pipe to each other.

In the case of repair work of water and sewage pipes buried underground due to urbanization, among the non-drilling methods that can solve the difficulties of excavation, the reinforced tube hardening method is made by impregnating the resin with a polymer-coated nonwoven fabric to heat the tube with hot air or hot water The method of heat curing using is widely used.

There are two methods of repairing a non-dig type pipe using an impregnated tube: a towing method, a reversing method, and a modified method. In the case of the reversing method, the extension of the one-time construction is limited due to the limitation of the capacity of the reversing tank that loads the impregnating tube, and the construction is difficult in a narrow area due to the large reversing device. As the length of the tower increases, a lot of material loss and waste materials are generated, and during the construction, the rod part of the tube bursts, which may result in impossibility of construction and defects.

A construction device and a construction method have been developed to increase the efficiency and continuity of construction by reversing the impregnating tube by attaching and detaching a reversing box to a rotatable reversing device according to the site conditions.

There have been many studies to solve this problem.
