Description
Technical field
The utility model belongs to pipe laying technical field, particularly relates to a kind of inspection shaft piping displacement elastic compensator.
Background technique
In road construction process, need to carry out under ground piping to lay and inspection shaft construction operation, the borehole wall of inspection shaft offers the preformed hole in poling road, the junction of the pipeline outer wall laid and borehole wall preformed hole is for being rigidly connected, when crossing heavy-load automobile, the backfill of inspection shaft and surrounding thereof just there will be the inconsistent situation of sedimentation, namely the sedimentation of backfill and pipeline is greater than inspection shaft sedimentation size, there is stress and concentrate in the borehole wall junction of pipeline outer wall and inspection shaft, special easier in breaking for plastic pipe, thus cause the generation of water leakage phenomenon.This phenomenon is more serious when backfill operation is lack of standardization, therefore, needs solution the above-mentioned problems in the prior art badly.
In addition, number of patent application be 201210287532.9 Chinese invention patent disclose a kind of pipeline displacement compensator, number of patent application be 201210366630.1 Chinese invention patent disclose 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 which.
2, when the size in radial directions of the O-ring seal in sleeve pipe is larger, production mould cannot the demoulding after formed product, there will be the damage of O-ring seal like this, produce more substandard products when the demoulding.
3, the stiffening ring of rigidity is not clearly set at the two ends of sleeve pipe, often sleeve pipe two-port place is trampled when constructing like this, making the destruction in conjunction with aspect of sleeve pipe outer circumferential face and inspection shaft body of wall, cause infiltration after construction and cause the inefficacy of product effect.
4, when carrying out backfill operation, grave mound easily enters in the cavity of sleeve pipe, along with the vibrations of vehicle pass-through road pavement, the backfill near pipeline and inspection shaft outer wall is loosened, finally causes the sedimentation and deformation of sub-surface.
Model utility content
The utility model, in order to solve deficiency of the prior art, provides a kind of relative displacement producing 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 when effectively reducing heavy duty.
For solving the problems of the technologies described above, the utility model adopts following technological 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 seal ring, internal diameter of the seal ring is less than outer diameter tube, and the angle of the radial cross section of seal 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 true dip direction of the radial cross section of grave mound ring is met when mounted outside inspection shaft, and grave mound ring internal diameter is less than outer diameter tube.
Be provided with the support ring being positioned at sleeve pipe two ends in described sleeve pipe, support ring is that rigid material is made.
Described seal ring is provided with twice, and internal surface of sleeve pipe is provided with the demoulding slot to make way of annular at the root place closing on wherein one seal ring.
The angle of the radial cross section of described seal 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 seal ring adopt specialized mould one-body molded.
Adopt technique scheme, when carrying out under ground piping and laying with inspection shaft construction operation, first sleeve pipe is enclosed within pipeline by inspection shaft to the direction outside inspection shaft, seal ring and pipeline fit tightly and contact and sealed by pipeline external surface, the toroidal cavity formed between pipeline external surface and internal surface of casing is intercepted by seal ring, so just plays the effect that anti-sealing flows outside inspection shaft along pipeline outer wall.Seal ring is obliquely installed, in fact the axial length adding sealing is equaled, namely add the admissible relative shift of pipeline enclosure on inspection shaft, be convenient to the effect be installed to by sleeve pipe on pipeline like this, finally again pipeline is placed into specified position and carries out building inspection shaft operation by laying bricks or stones.
Pipeline and inspection shaft produce the relative displacement of Vertical direction, by the buffering of seal ring, guarantee that seal ring still fits tightly with pipeline external surface, ensure good sealability.
Arrange support ring respectively at sleeve pipe two ends, when making inspection shaft construct like this, workmen tramples the position of stretching out inspection shaft wall and can guarantee that sleeve pipe is indeformable.Being provided with of demoulding slot to make way is beneficial to the demoulding, reduces the reject rate 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 the grave mound outside inspection shaft can not enter in toroidal cavity like this; thus guarantee backfill degree of compaction; it also avoid backfill may to enter in cavity of the present utility model and to cause seal failure; even if what ensure that sub-surface is subject to vehicle rolls vibrations, also there will not be the situation of collapse-deformation.
The utility model structure is simple, reliability is strong, even if the relative displacement that pipeline and inspection shaft produce Vertical direction still has excellent sealing effect, solve inspection shaft and pipeline enclosure to produce because of relative displacement and mutually destroy and the seepy question that causes, and be convenient to the demoulding, decrease the reject rate of product, not yielding, buried pipeline can be ensured not by the restriction of inspection shaft body of wall, with the change free-extension of ambient temperature, thus eliminate inspection shaft body of wall and suffer cracking destruction because of the axial stretching of pipeline, avoid the therefore road collapsion caused.
