Technical field
The utility model relates to pipe technology field, specifically a kind of sheath device of pre-stress steel cylinder RC pipejacking interface.
Background technique
At present, Prestressed concrete cylinder pipe, code name PCCP manages, and applies very extensive in Chinese large-sized water and wastewater piping engineering.But Prestressed concrete cylinder pipe generally adopts embed pipe with trough method burial and construction.Because embed pipe with trough method of construction will take ground level road in a big way temporarily, comparatively large to urban environment and traffic impact, therefore be difficult to implement in big and medium-sized cities.
In field of urban drainage, adopt the reinforced concrete pipiline of pipe jacking method very extensive.In the line sewage transport engineering of south, Shanghai White dragon port, pipe jacking method has successfully been adopted to implement reinforced concrete pipiline more than 40 kilometer that maximum caliber is four meters.But to be that pipeline is resistance to force down the maximum defect of reinforced concrete pipiline, is generally no more than 0.2 MPa, is confined to apply in drainage works.
In order to improve the compressive strength of pipeline, R & D design pre-stress steel cylinder RC pipejacking in recent years, code name JPCCP manages.The resistance to interior hydraulic pressure value of this pipeline is more than 1 MPa.Have employed the sealed interface form of the steel joint socket of PCCP pipe due to JPCCP pipe, joint socket is positioned at insides of pipes, therefore pipe joint seam, wooden dunnage and adjacent mud injected hole be all directly in exposed stratum outside JPCCP pipe.This structural type, two kinds of adverse effects will be produced: 1. in jack-in process to JPCCP pipe construction, silt particle in stratum may enter in the seam of JPCCP pipe, and particularly sand particle alluvial in the joint, may affect the free deflection of push pipe seam, cause the obstacle of JPCCP top pipe deviation correcting, now, some units enter to prevent silt particle, adopt the seal arrangement of steel structure, not only cost is very high, but also produces the secondary technical problem of negative pressure due to interface dilatation; 2. mud injected hole is generally 3-4 spot distribution in JPCCP pipe periphery, is unfavorable for the diffusion of mud, is difficult to form complete mud sleeve fast in push pipe periphery, particularly unfavorable to long-distance pipe jacking to push pipe.Above-mentioned two point defects of JPCCP pipe, become the technical bottleneck of JPCCP pipe further genralrlization application under all kinds of geological condition.
Therefore, need design one can either prevent silt from entering seam, the mud that injected hole can be made again to spray can scatter rapidly along push pipe periphery, and forms the sheath device of the pre-stress steel cylinder RC pipejacking interface of mud sleeve.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, providing one can either prevent silt from entering seam, the mud that injected hole can be made again to spray scatters along push pipe periphery, and forms the sheath device of the pre-stress steel cylinder RC pipejacking interface of mud sleeve fast.
In order to achieve the above object, the utility model is a kind of sheath device of pre-stress steel cylinder RC pipejacking interface, comprise bellmouth steel bushing, socket steel bushing, sealing joint glue and deal board, it is characterized in that: the seam crossing of socket steel bushing and bellmouth steel bushing is provided with deal board, the end of deal board is filled with sealing joint glue, sealing joint glue is between bellmouth steel loop and socket steel ring, the outer wall of socket steel bushing and bellmouth steel bushing seam crossing is arranged with rubber sheath, the end of rubber sheath extends and covers on the spout of mud slurry injection pipe, the end of rubber sheath is provided with annular groove, the location matches of the spout of annular groove and mud slurry injection pipe.
The sealing sheath that described rubber sheath and described sealing joint glue are formed.
Described rubber sheath is moulded boot band and socket steel by bellmouth steel and is moulded boot band and be positioned at respectively on socket steel bushing and bellmouth steel bushing.
The outer surface of described sealing joint glue flushes with the end outer surface of bellmouth steel loop and socket steel ring.
The utility model compared with the existing technology, set up the rubber sheath device of pre-stress steel cylinder RC pipejacking interface, rubber sheath can not only effectively prevent silt particle from entering seam, the annular groove of rubber sheath end can make slip casting evenly spread at tube circumference and form complete mud sleeve fast, decrease the resistance of pre-stress steel cylinder RC pipejacking, the pre-stress steel cylinder RC pipejacking especially for heavy caliber, long distance is favourable.The features such as the utility model had both had that structure is simple, technically reliable, construction and installation are easy and with low cost, also make pre-stress steel cylinder RC pipejacking interface structure more ripe and perfect, the reliability of engineering improves more, thus application area is more expanded, produce larger economic and social benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
See Fig. 1,1 is rubber sheath; 2 mould boot band for socket steel; 3 is socket steel ring; 4 is sealing joint glue; 5 is bellmouth steel loop; 6 mould boot band for bellmouth steel; 7 is bellmouth steel bushing; 8 is deal board; 9 is mud slurry injection pipe; 10 is socket steel bushing.
Embodiment
Now by reference to the accompanying drawings the utility model is described further.
See Fig. 1, the sheath device of a kind of pre-stress steel cylinder RC pipejacking of the utility model interface, comprises bellmouth, socket, sealing joint glue and deal board.Socket steel bushing 10 and bellmouth steel bushing 7 seam crossing are provided with multilayer or deal board 8, the end of multilayer or deal board 8 is filled with sealing joint glue 4, sealing joint glue 4 is between bellmouth steel loop 5 and socket steel ring 3, the outer wall of socket steel bushing 10 and bellmouth steel bushing 7 seam crossing is arranged with rubber sheath 1, the end of rubber sheath 1 extends and covers on the spout of mud slurry injection pipe 9, the end of rubber sheath 1 is provided with annular groove, the location matches of the spout of annular groove and mud slurry injection pipe 9.Annular groove makes mud under pressure in ejection process, is constantly shunted by annular groove and is evenly diffused into pipe circumference and forms complete mud sleeve.
In the utility model, the sealing sheath that rubber sheath 1 and sealing joint glue 4 are formed, when the jacking of pre-stress steel cylinder RC pipejacking, sealing sheath is along with interface opening and closing resiliently deformable, due to the elastic reaction of rubber sheath 1, the tensile buckling of the opening and closing 85mm of pre-stress steel cylinder RC pipejacking seam can be adapted to.Rubber sheath 1 can not only prevent the silt particle in stratum from entering interface, prevents silt blocking and guarantees the free deformation of pre-stress steel cylinder RC pipejacking interface in jacking and correction.
Rubber sheath 1 moulds boot band 6 by bellmouth steel and boot band 2 moulded by socket steel, bellmouth steel is moulded boot band 6 and socket steel and is moulded boot band 2 and be securely fixed on the port of socket steel bushing 10 and bellmouth steel bushing 7 by rubber sheath 1, thus has completely cut off being communicated with of the push pipe seam that is made up of sealing joint glue 4 and multilayer or deal board 8 and outside stratum.
The outer surface of sealing joint glue 4 flushes with the end outer surface of bellmouth steel loop 5 and socket steel ring 3, is beneficial to the smooth of rubber sheath 1, and the elastic plastics characteristic of option interface sealer 4 can guarantee sealing joint glue 4 and rubber sheath 1 deform in same pace.
Bellmouth steel loop 5 and socket steel ring 3, to rubber sheath 1 position-limiting action, play reinforcement effect to the structure of pre-stress steel cylinder RC pipejacking joint socket, to improve the axis top power transmitted by pre-stress steel cylinder RC pipejacking interface.
Multilayer or deal board 8 are the cushion that pre-stress steel cylinder RC pipejacking top power is transmitted.
