Description
Technical field
The utility model belongs to the complicated geologicals item such as underground piping recovery technique more particularly to soft layer, drift sand, underground river
Underground piping pipeline section, which comes to nothing, under part administers method for grouting polymers.
Background technique
Underground pipe network is the important component of urban infrastructure, be the material base depended on for existence and development of city and
Indispensable lifeline.In recent years, with the reinforcement of people's awareness of safety and environmental consciousness, the safety of underground piping by
More and more concerns.
Underground piping category concealment engineering, since China's complex geologic conditions are changeable, underground piping is in process of construction soil layer
It is not compacted to be easy to appear tube bottom to come to nothing phenomenon.If dealt with improperly, easily there is the dislocation of pipeline section seam crossing in underground piping after building up, and makes
At leaking, gushing sand, light then silting pipeline influences it using function, serious to even result in surface subsidence, traffic jam, personnel
Injures and deaths threaten the safety of buildings or structures nearby.
There are two main classes for existing underground piping method for maintaining: one kind is trenchless rehabilitation, and another kind of is trenchless repairing method.
Trenchless rehabilitation method, which refers to, excavates soil layer above broken pipe position, carries out local route repair to broken pipe or integral replacing is newly managed
The method in road.Although this method can effectively solve pipeline section settlement issues, such methods construction cost is high, long in time limit, applies
Work area resident living and traffic are heavily disturbed, and in many cases the underground infrastructure of urban compact, ground it is green
Change area and building housing-group and busy traffic, the leeway very little of excavation construction is left for, so that the reparation of underground piping is replaced
It can not achieve at all.Trenchless repairing method mainly has in-situ solidifying method at present, Insertion method, booster method, folds Internal Lining Method and spray
Coating etc..
High polymer grouting technology is the ground rapid reinforcement technology that 1970s grow up.The technology is by ground
Non-aqueous reaction class double component high polymer material is injected in base, reacts expansion and cured spy after mixing using two kinds of materials rapidly
Property, achieve the purpose that consolidated subsoil, fill and come to nothing or promoted floor.High polymer material has light weight, and reaction is fast, durability
Well, the features such as barrier performance is excellent.Currently, high polymer grouting technology be mainly used in road, tunnel, dykes and dams, etc. large foundations
In facility antiseepage, reinforcing and recovery project.The present inventor be directed to China's complex geological condition under underground piping maintenance technique not
Foot invents a kind of underground piping fixed point prosthetic appliance in conjunction with high polymer pouch slurry injection technique.The current country of this innovation yet there are no
Relevant report.
Utility model content
The utility model aim is problem of coming to nothing for underground under complex geological condition, develops a kind of underground piping fixed point
Prosthetic appliance provides advanced, efficient, economic, practical technical measures for the Defects Treatment that comes to nothing of pipeline under complex geological condition.
In order to achieve the above technical purposes, the utility model uses following technical scheme:
The utility model relates to a kind of underground piping pinpoint prosthetic appliance, including underground piping, grouting equipment and support
Connector；Support joint upper end connects slip casting steel pipe, and lower end connects pouch, and support joint is by threaded connector, spring, supporting steel
Plate and end branch fastener composition；Pouch and threaded end is prefabricated links together, also has connection ring in pouch；Slip casting steel pipe
One end is connected with slip casting hose, and the other end is connected with support joint；Slip casting hose upper end connects grouting equipment.
Preferably, the support joint includes at least 3 pieces of supporting steel plates, and supporting steel plate passes through spring and threaded connector
It is connected with end branch fastener, threaded connector and the welding of end branch fastener.
Preferably, the threaded end uses rubber material, includes through hole, and threaded end is that spiral shell is wrapped up in outer surface
The annulus of line aluminium skin.
Preferably, slip casting steel pipe lower end and threaded connector are cooperatively connected.
Preferably, threaded end and end branch fastener are cooperatively connected, the connection ring and supporting steel plate bottom in pouch
Stay hook is cooperatively connected.
The utility model have the characteristics that and the utility model has the advantages that
(1) pipeline is carried out using no-dig technique mode to come to nothing reparation, quick construction, low cost, maintenance effect be good, to pipeline without
The features such as disturbance；
(2) it combines Ground Penetrating Radar to carry out high polymer grouting in the default point of pipeline, has slip casting effect good, repair time is fast
Feature；
(3) material that prosthetic appliance uses is prefabrication production, and some materials are reusable after the completion of construction, section
About construction cost.
(4) slip casting is oriented using pouch, and pouch is stretched with supporting steel plate, avoids pouch non-directional squeezed
So that pipeline secondary injury.
Generally speaking underground piping fixed point grouting equipment technical principle and in terms of all there is obvious innovation.
Have the characteristics that quick construction, low cost, maintenance effect it is good, to pipeline undisturbed, and be successfully applied in complicated geological environment
Underground piping comes to nothing harnessing project, huge economical, societal benefits and wide development and application prospect is shown, for pushing me
State's urban Underground pipeline maintenance level progress is of great significance.
