The methods of continuous partial work for anold and timeworn sewer pipe

摘要

PURPOSE: A continuous partial repair system for a degraded sewerage pipe is provided to prevent the breakdown of a sewerage pipe continuously, and to heighten the strength on the damaged part of a sewerage pipe and the efficiency on reinforcement by using glass fiber and reinforced concrete. CONSTITUTION: The continuous partial repair system for a degraded sewerage pipe comprises: a sewer pipe(1) installed on the lower part of the ground(2); two sewerage manholes(G) of the section for construction; a sewer pipe cover(20) closing up the sewer pipe(1) formed on the lower part of the final sewerage manhole(G); a dredging pipe(12) connected to a dredging vehicle(13) located on the road from the lower part of the first sewerage manhole(G); a bypass sewer pipe(11) connected to the sewer pipe cover(20) of the final sewerage manhole(G) through a sewerage feed pump(8) and the upper part of a road from the lower part of the first sewerage manhole(G); a sewer pipe protection unit located on the bypass sewer pipe(11) located on the road, a traction winch(3) installed on the rear of the road of the first sewerage manhole(G); a winch(4) and a various unit control box composed of a glass fiber generator, a central control box and a reinforced concrete generator/feed unit and installed on the front of the road of the final sewerage manhole(G); and a traction rope(5) connected to the front of various repair systems through a pulley(6) connected to the traction winch(3) and formed on the upper part of an opening of the sewer pipe(1) located on the lower part of the first sewerage manhole(G), and connected to the winch(4) through another pulley(6) which is connected to the rear of various repair systems and formed on the upper part of an outlet of the final sewerage manhole(G).
