Description
Technical field
The present invention relates to the repairing construction of underground sewer, relate in particular to a kind of heavy caliber underground sewer interface crack, repair of leakage construction treating methods, belong to the non-trenchless rehabilitation field of engineering technology of pipeline.
Background technology
The heavy caliber underground sewer mostly is the merogenesis combination and lays, come into operation afterwards because of various reasons such as natural environment, geology variation and last stressor layer differences, pipeline can become non-rectilinear by straight line, the pipe joint position distortion occurs and produces the crack, making underground water and underground water carry the pipeline soil body and silt particle all around secretly pours in the pipe, flow away with sewage, if things go on like this cause vicious circle.In the prior art, generally be to adopt cement to seal mending-leakage at its interface, this sealing craft leakage mending method is unable to undergo the test of time.Also have a kind of recovery technique to be in addition: the thickness about employing 10mm and the steel plate of the above width of 300mm divide 3 to be spliced into a circle, the external coating antifouling paint, through practical operation with use interpretation of result, this technology has following shortcoming: 1. constructing operation labour intensity big (heaviness); 2. operating pipeline must be cut off the water supply (the necessary shutoff in two), need set up interim water pump and carry out surmounting of sewage, increases the cost of engineering; 3. the repairing construction cycle is longer; 4. anticorrosion relatively poor, the antifouling paint on surface is easy to come off, and application life is short.
According to the knowledge of the applicant, still do not have preferably repair materials and construction technology at present underground sewage conduct is repaired, above-mentioned defective is ubiquity in the industry, and the interface renovation technique of large-scale pipeline will be an important technology problem that is worth research.
Summary of the invention
The purpose of this invention is to provide the job practices that a kind of underground sewer interface is repaired, be intended to effectively solve the problems such as crack, seepage of large diameter pipeline, improve construction quality and efficient, guarantee that underground sewer effectively comes into operation for a long time.
Purpose of the present invention is achieved through the following technical solutions:
The method that underground sewer is repaired, it is characterized in that: waterstop, interior packing and engagement connection mechanism are set, described waterstop is banded structure ringwise, its material is a neoprene, waterstop is fitted in the joining place of two sections underground sewers, the one side of waterstop is fitted with the pipeline inner headed face, and the another side of waterstop matches with the periphery of interior packing; Packing is connected by the interior packing body of two sections arcs forms at least in described, be connected by engagement connection mechanism between the end of packing body in the two neighboring sections, the interior packing body of described at least two sections arcs constitutes closed round ring shape under the spreading state, waterstop is closely sealed with the abutting end driving fit of two sections tube connectors, be one thereby the tube connector sealing is connected.
Purpose of the present invention can also come further to realize by the following technical programs:
The method that aforesaid underground sewer is repaired, wherein, every suit engagement connection mechanism comprises two anchor ears, two support joint, two fasteners and bolts, two anchor ears are connected the end with two of interior packing body respectively and fix, one anchor ear connects a support joint, and fastener flexibly connects for the card slot type wedge shape with the support joint, by two fasteners two support joints is fastened, by bolt thereby the clamping of two fasteners is driven two support joints and move packing body spreading in making round about.
The method that aforesaid underground sewer is repaired, wherein, the material of described anchor ear, support joint, fastener and bolt all is a stainless steel; The material of packing is a stainless steel in described.
The method that aforesaid underground sewer is repaired, wherein, the surface that described waterstop and tube connector fit is provided with seal groove.
The method that aforesaid underground sewer is repaired, wherein, described waterstop is provided with groove with the surface that interior packing matches, and correspondingly, the matching surface of interior packing is provided with the convex raceway groove.
The method that aforesaid underground sewer is repaired, wherein, described interior packing is made of the interior packing body of three sections arcs.
The method that aforesaid underground sewer is repaired, wherein, the internal diameter of described underground sewer is 80～220cm.
The outstanding substantive distinguishing features and the obvious improvement of technical solution of the present invention is mainly reflected in:
The present invention connects and composes interior packing to the interior packing body of at least two sections arcs, make interior packing spreading by engagement connection mechanism, then the outer wall surface of interior packing can prop up the waterstop at pipeline joint-seam place, and packing swelling firmly reaches and prevents the effect of leaking on inner-walls of duct in making.This scheme is installed fast, need not envelope, tears the chieftain open, can be with the water operation during the operation low ebb, and operation does not have influence substantially to pipeline, does not need to cut off the water supply.Because construction fast, has therefore significantly reduced the open-assembly time of constructor at the down-hole hazardous environment, safety of construction, constructor's life support is greatly improved; The interface withstand voltage reaches 1.5kg/cm
2, the highlyest can reach 1.8kg/cm
2, stagnant water effect is good.The present invention is applicable to the underground sewer of various calibers, various interface form, and scheme is easily implemented, and compliance is strong, can in the field of businessly promote the use of, and has good economic benefit and social benefit.
