Embodiment Construction

[0026] The method comprises the steps of:

[0027] Step 1, setting the lining plate 13: place a lining board 13 on the inner wall corresponding to the damaged hole 1 on the pipeline, the radian of the lining board 13 coincides with the inner wall radian of the pipeline; the lining board 13 The size should ensure that the inner liner 13 can be put into the pipeline through the damaged hole 1, and after being put in, it can completely cover the damaged hole 1 on the inner wall of the pipeline, and a bracket 12 is set outside the pipeline corresponding to the damaged hole 1 ;

[0028] Step 2, install the cover plate: put the cover plate 18 and the top plate 17 on the screw rod 16, and then connect the screw rod 16 to the inner lining plate 13; set the cover plate hole 22 on the cover plate 18; The liner 13 is connected to the bracket 12 by the screw 16;

[0029] Step 3, repairing the inner tube core: fill the pit corresponding to the inner liner 13 on the pipeline with concrete...

Abstract

The invention relates to a pipelining emergent repairing method of an underground prestressing steel cylinder concrete pipe (hereinafter referred as to PCCP), in particular to an emergent repairing method for PCCP pipeling damaged by external force. According to the technical solution of the invention, a lining plate is arranged in the inner wall of a pipeline which corresponds to a damaged opening; a screw is arranged on the lining plate; a cover plate which covers the damaged opening is arranged on the external surface of the pipeline which corresponds to an exposed steel cylinder at the damaged opening; a rubber ring is arranged between the cover plate and the steel cylinder; the cover plate and the lining plate are mutually connected; a hollow cavity between the cover plate and the lining plate is filled with concrete; a steel plate which is connected with a sample plate is arranged above the cover plate; and the hollow cavities among the steel plate, the cover plate and a top plate are filled with fine stone concrete. The method can solve the problem that the usual repairing method takes much time, has great waste, high cost, etc.

Description

technical field [0001] The invention relates to a method for repairing underground prestressed steel cylinder concrete pipe (hereinafter referred to as PCCP) pipeline, in particular to an emergency repair method for PCCP pipeline damaged by external force. Background technique [0002] The invention is mainly used for emergency repair after the PCCP pipeline is damaged by external force and leaks water. After the PCCP pipeline is buried, sometimes it is accidentally driven by the piling machine because the bottom line pipeline route is unknown, resulting in pipeline leakage. The traditional repair method is to smash the damaged PCCP pipe completely, clean it out, and then replace it with steel pipe fittings For the vacant PCCP, such a repair method needs to empty the water in the original pipeline before the operation can be carried out. Assuming that the damaged pipeline is 10 kilometers long and the pipe diameter is 2 meters, more than 30,000 tons of water need to be drain...
