Background
In municipal pipeline construction and building district pipeline construction, the main effect of inspection shaft is to make things convenient for maintenance work such as pipeline desilting, mediation and restoration. The inspection well is corroded by waste liquid and waste gas for a long time, bears live loads of vehicles on the road surface, bears soil pressure of soil bodies around the outside and underground hydrostatic pressure, and is very easy to damage. In response to this situation, it is necessary to repair the manhole in a timely manner to prevent further deterioration. When the inspection well is repaired, continuous drainage is needed, and the well is kept dry, so that special equipment is needed for drainage and plugging.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the invention provides a temporary discharge pipe with an air bag expansion plug for repairing an inspection well, which can be used for plugging and draining pipelines at the upstream and the downstream of the inspection well.
The utility model provides an inspection shaft restores uses interim delivery pipe with gasbag inflation end cap, includes cylindric drainage tube 1, its characterized in that: the temporary discharge pipe with the air bag expansion plug for repairing the inspection well further comprises a circular flange plug 2 which is arranged at two ends of the drainage pipe 1 and can be matched with an upstream pipeline and a downstream pipeline of the inspection well; the circumferential side surface of the flange plug 2 is formed with a recess, and the recess is internally provided with an inflatable annular air bag 3.
Therefore, the annular air bag can seal up the upstream and downstream pipelines, guide water flow into the drainage tube and keep the interior of the inspection well dry.
According to inspection shaft restoration with gasbag inflation end cap use interim delivery pipe, its characterized in that: a check valve 4 is arranged in the drainage tube 1.
This prevents backflow of the drain water.
According to inspection shaft restoration with gasbag inflation end cap use interim delivery pipe, its characterized in that: the drainage tube 1 can be split into a plurality of parts and fixed by watertight bolts.
Therefore, the underground inspection well can be conveniently transported and enter the underground, and is matched with inspection wells with different sizes.
According to inspection shaft restoration with gasbag inflation end cap use interim delivery pipe, its characterized in that: two ends of the drainage tube 1 are steel tubes, and the middle parts of the drainage tube are connected through a hose 5.
Thereby, different lengths and sizes of pipes can be accommodated.
According to inspection shaft restoration with gasbag inflation end cap use interim delivery pipe, its characterized in that: the annular air bag 3 is an annular air bag with the inflation thickness of 20 mm-200 mm, and is suitable for pipelines with the pipe diameter of 300mm-1200 mm.
According to inspection shaft restoration with gasbag inflation end cap use interim delivery pipe, its characterized in that: the annular air bag 3 is an annular air bag with an inner circle and an outer square, and is suitable for a rectangular pipeline of a concrete box culvert with the thickness of 500mm multiplied by 500 mm-1000 mm multiplied by 1000 mm.
Therefore, the inspection well can be adapted to inspection wells of different models by replacing the annular air bags with different shapes, thicknesses and widths.
According to an inspection shaft restoration is with interim delivery pipe with gasbag inflation end cap, transportation, simple to operate can correspond multiple tubular and pipe diameter, can be at water level and below 40cm below the pipe diameter 1/3, install when the velocity of water is below 0.6 m/s. The water is not leaked under the water pressure of 0.06MPa, and the water can be kept for more than 20 days after being set once.
