Description
Technical field
The present invention relates to the method for repairing and mending of a kind of underground Prestressed concrete cylinder pipe (hereinafter to be referred as PCCP) pipeline, specifically a kind of PCCP pipeline is subjected to the emergency first-aid repair method of external force breakage.
Background technique
The present invention is mainly used in the PCCP pipeline and is subjected to emergency first-aid repair after the external force breakage is leaked.After the PCCP pipeline is buried underground, beaten because of bottom line pipeline circuit is failed to understand to miss by piling machinery sometimes, cause the pipeline seepage, traditional emergency repair method is that the PCCP pipe of this joint damage is thoroughly smashed, clear, replace the PCCP of this place's vacancy then with steel pipe fittings, such emergency repair method need be the water emptying in the original pipeline, just can carry out operation then, suppose 10 kilometers of impaired lengths of pipeline, 2 meters of pipe bores need more than 30,000 ton of water of emptying, and waste is big, the time of draining may be very long, and the activity duration of replacing impaired PCCP with steel pipe fittings is also very long, and the very long meeting of trunk line water stopping time causes very big loss to life of urban resident and industrial water.
Summary of the invention
The objective of the invention is to design a kind of Prestressed concrete cylinder pipe pipelining emergent repairing technology, big to solve common emergency repair method time length, waste, problems such as expense height.
According to technological scheme provided by the invention, described method comprises the steps:
Before interior lining panel is set, earlier carry out model, and it is standby to cut away a block plate according to the shape at damaged hole and size on model greater than damaged hole by the shape at damaged hole; Outside the pipeline around the damaged hole, cover rubber plate again, on described rubber plate, cut out the shape at damaged hole equally greater than damaged hole; Again model is pressed on the rubber plate, and makes hole and the hole on the model on the rubber plate all aim at damaged hole; Wearing the anchor ear of some strips below pipeline, all fixedlys connected with the lower limb of model in the end of all anchor ears, realizes preliminary pretension.
In step 1, suspension ring are set on interior lining panel earlier, when interior lining panel passes through damaged hole, pass described suspension ring with rope, then described interior lining panel is put into damaged hole, and utilize rope to be hung on the support.Long nut is set on interior lining panel; In step 3, when cover plate and interior lining panel are linked together, utilize bolt to pass hole on the cover plate, be screwed onto with long nut.In step 3, after the outer surface of described steel cylinder is placed rubber ring, coat polysulfide sealant on the outer surface of the steel cylinder outside rubber ring again.In step 3, after cover plate and interior lining panel are linked together, with top board cover board hole is sealed again, and top board and cover plate and screw rod are fixed together.In step 4, after steel plate and model are fixed together, are screwed onto on the screw rod with nut again, and clip the redundance of screw rod.
A kind of Prestressed concrete cylinder pipe pipelining emergent repairing structure, it is characterized in that: the inwall corresponding to damaged hole on pipeline is provided with interior lining panel, on described interior lining panel, screw rod is set, on pipeline, cover the cover plate at damaged hole, between cover plate and steel cylinder, rubber ring is arranged corresponding to the outer surface setting of the exposed steel cylinder in place, damaged hole; Described cover plate and described interior lining panel interconnect, and fill up concrete in the cavity between cover plate and interior lining panel; The steel plate that is connected on the model is being arranged above the cover plate, filling up pea gravel concreten in the cavity between described steel plate and cover plate and top board.
Coat polysulfide sealant on the outer surface of the steel cylinder outside rubber ring; Long nut is set on interior lining panel; Cover plate and interior lining panel utilize bolt to pass hole on the cover plate, are screwed onto with long nut; Cover board hole is on the cover board arranged, on cover plate, be provided for covering the top board of described cover board hole.
Model greater than damaged hole is arranged outside the pipeline corresponding to 1 place, damaged hole, and it is standby to cut away a block plate according to the shape at damaged hole and size on model; Outside the pipeline around the damaged hole, cover rubber plate, on described rubber plate, cut out the shape at damaged hole equally greater than damaged hole; Described model is pressed on the described rubber plate, and makes hole and the hole on the model on the rubber plate all aim at damaged hole; Wearing the anchor ear of some strips below pipeline, all fixedlys connected with the lower limb of model in the end of all anchor ears.
Advantage of the present invention is: general damaged openning is all at the upper half of pipe, this method does not need all water in the emptying pipe, only need reduce to liquid level below damaged mouthful and just can carry out operation, and the repairing time is short, not waste water resource, and expense is also much lower than traditional method.
