Description
Technical field
The invention belongs to pipeline laying technical field, relate in particular to a kind of inspection shaft piping displacement elastic compensator.
Background technology
In road construction process, need to carry out underground piping lays and inspection shaft construction operation, on the borehole wall of inspection shaft, offer the preformed hole in poling road, the junction of the pipeline outer wall laying and borehole wall preformed hole is for being rigidly connected, in the time crossing heavy-load automobile, the backfill soil of inspection shaft and surrounding thereof just there will be the inconsistent situation of sedimentation, the sedimentation that is backfill soil and pipeline is greater than inspection shaft sedimentation size, the borehole wall junction of pipeline outer wall and inspection shaft exists stress to concentrate, especially for plastic conduit more easily in breaking, thereby cause the generation of drainage. This phenomenon is more serious in the time that backfill soil operation is lack of standardization, therefore, needs solution the above-mentioned problems in the prior art badly.
In addition, the Chinese invention patent that number of patent application is 201210287532.9 discloses a kind of piping displacement compensator, and the Chinese invention patent that number of patent application is 201210366630.1 discloses a kind of elastic displacement compensator. All there is following defect in the motion compensator of these two kinds of structures:
1, not clear and definite pipeline and inspection shaft produce the relative displacement of vertical direction, and solution when relative displacement is larger between them.
2, the O-ring seal in sleeve pipe is in the time that size is in the radial direction larger, and production mould cannot the demoulding after formed product, there will be like this damage of O-ring seal in the time of the demoulding, produces more substandard products.
3, the reinforcing ring of rigidity is not clearly set at the two ends of sleeve pipe, time often sleeve pipe two-port place is trampled in construction like this, make the destruction of the combination aspect of sleeve pipe outer peripheral face and inspection shaft body of wall, after construction, cause seeping water and cause the inefficacy of product effect.
4, in the time carrying out backfill soil operation, grave mound easily enters in the cavity of sleeve pipe, along with the vibrations of vehicle pass-through road pavement, makes near the backfill soil of pipeline and inspection shaft outer wall loosening, finally causes the sedimentation and deformation of sub-surface.
Summary of the invention
The present invention is in order to solve weak point of the prior art, provides a kind of relative displacement that produces vertical direction for pipeline and inspection shaft still to keep good sealing property, the inspection shaft piping displacement elastic compensator of the borehole wall junction stress of pipeline outer wall and inspection shaft while effectively reducing heavy duty.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: inspection shaft piping displacement elastic compensator, comprise the sleeve pipe with cylindrical cavity, sleeve pipe is made by playing flexible material, described internal surface of sleeve pipe is provided with at least one sealing ring, internal diameter of the seal ring is less than outer diameter tube, and the angle of the radial section of sealing ring and the axial direction of sleeve pipe is less than or equal to 90 °.
Described sleeve pipe one end is provided with grave mound ring, and the incline direction of the radial section of grave mound ring is met when mounted to inspection shaft outside, and grave mound ring internal diameter is less than outer diameter tube.
In described sleeve pipe, be provided with the support ring that is positioned at sleeve pipe two ends, support ring is that rigid material is made.
Described sealing ring is provided with twice, and internal surface of sleeve pipe is provided with annular demoulding slot to make way closing on the wherein root place of one sealing ring.
The angle of the radial section of described sealing ring and the axial direction of sleeve pipe is acute angle.
Surface blending between the inwall of described sleeve pipe and the end face of the other end.
Described sleeve pipe and sealing ring adopt particular manufacturing craft one-body molded.
Adopt technique scheme, carrying out underground piping while laying with inspection shaft construction operation, first sleeve pipe is enclosed within on pipeline by the direction outside inspection shaft in inspection shaft, sealing ring fits tightly and contacts and pipeline external surface is sealed with pipeline, the sealed circle of the toroidal cavity that forms between pipeline external surface and internal surface of casing intercepts, and so just plays anti-sealing along pipeline outer wall mobile effect outside inspection shaft. Sealing ring is obliquely installed, in fact equaled to increase the axial length of sealing, increased the admissible relative shift of pipeline enclosure on inspection shaft, be convenient to like this sleeve pipe to be installed to the effect on pipeline, finally again pipeline has been placed into assigned address and builds inspection shaft operation by laying bricks or stones.
Pipeline and inspection shaft produce the relative displacement of vertical direction, by the buffering of sealing ring, guarantee that sealing ring still fits tightly with pipeline external surface, ensures good sealing property.
At sleeve pipe two ends, support ring is set respectively, makes like this inspection shaft when construction workmen trample to stretch out the position of inspection shaft wall can guarantee that sleeve pipe is indeformable. Being provided with of demoulding slot to make way is beneficial to the demoulding, reduces the percent defective of product. Surface blending between the inwall of sleeve pipe and the end face of the other end, is convenient to be located in pipeline from this end like this.
Grave mound ring also contacts with pipe surface; can ensure that like this grave mound outside inspection shaft can not enter in toroidal cavity; thereby guarantee backfill soil packing; also avoided backfill soil may enter in cavity of the present invention and caused seal failure; even if ensure that sub-surface is subject to the vibrations that roll of vehicle, also there will not be the situation of collapse-deformation.
The present invention is simple in structure, reliability is strong, even if producing the relative displacement of vertical direction, pipeline and inspection shaft still have excellent sealing effect, solve inspection shaft and the pipeline enclosure seepy question that mutual destruction causes because relative displacement produces, and be convenient to the demoulding, reduce the percent defective of product, not yielding, can ensure that buried pipeline is not subject to the restriction of inspection shaft body of wall, with the variation free-extension of environment temperature, thereby eliminate inspection shaft body of wall and suffered cracking destruction because of the axial stretching of pipeline, avoided the road collapsion therefore causing.
