Abstract
The invention discloses a pipeline displacement compensator, which comprises a sleeve with a cylindrical cavity, wherein a lower half circle of one end part of the sleeve and an upper half circle of the other end part of the sleeve or the whole circle of two end parts of the sleeve is provided with a flexible rebounding element, and the surface of the flexible rebounding element is parallel to the inner wall of the sleeve. After soil is refilled and the pavement is trimmed, when a heavy load passes through the top of an inspection well, the inspection well and the refilling soil around the inspection well can generate the condition of inconsistent sedimentation, i.e. the sedimentation size of the refilling soil and a pipeline is greater than the sedimentations size of the inspection well, but the upper part of the inner side and the lower part of the outer side of a connecting part of the well part of the inspection well and the pipeline are provided with the flexible rebounding element, the flexible rebounding element realizes good buffer and displacement compensation effects, in addition, the stress concentration condition is greatly reduced, and after the heavy load passes, the pipeline can recover the original state under the effect of the flexible rebounding element, so the damage condition during the heavy load is avoided.
Description
Technical field
The invention belongs to the pipe laying technical field, relate in particular to a kind of piping displacement compensator.
Background technique
In the road construction process; Need carry out under ground piping and lay and the inspection shaft construction operation, offer the preformed hole in poling road on the borehole wall of inspection shaft, the junction of pipeline outer wall that lays and borehole wall preformed hole is for being rigidly connected; When crossing heavy-load automobile; The inconsistent situation of sedimentation will appear in inspection shaft and backfill all around thereof, i.e. the sedimentation of backfill and pipeline is greater than inspection shaft sedimentation size, and the borehole wall junction of pipeline outer wall and inspection shaft exists stress to concentrate; Especially for plastic pipe more easily in breaking, thereby cause the generation of water leakage phenomenon.This phenomenon is more serious when the backfill operation is lack of standardization, therefore, needs badly and solves the problems referred to above that exist in the existing technology.
Summary of the invention
The present invention is in order to solve deficiency of the prior art, and a kind of piping displacement compensator of the borehole wall junction stress of pipeline outer wall and inspection shaft when reducing heavy duty effectively is provided.
For solving the problems of the technologies described above; The present invention adopts following technological scheme: the piping displacement compensator; Comprise sleeve pipe with cylindrical cavity; Half-turn or sleeve pipe two end part one whole circle are provided with flexible resilience part on sleeve pipe one end lower branch and the other end, and flexible resilience part surface is equal with internal surface of sleeve pipe.
Said internal surface of sleeve pipe is provided with seal groove at least one.
Said sleeve pipe outer ring is provided with at least one external sealed groove.
Adopt technique scheme,, sleeve pipe is installed in the preformed hole of the inspection shaft borehole wall carrying out under ground piping when laying with the inspection shaft construction operation.If half-turn is provided with the sleeve pipe of flexible resilience part on employing one end lower branch and the other end; The end that the sleeve pipe lower branch has flexible resilience part is positioned at the inspection shaft outside; The end that half-turn has a flexible resilience part on the sleeve pipe is positioned at the inspection shaft inboard, like this can economical with materials, reduce cost; If adopt two end part one whole circle to be provided with the sleeve pipe of flexible resilience part, can install by any direction.And then pipeline penetrated in the cylindrical cavity of sleeve pipe again; When pipeline is bellows; Ripple and interior seal groove are sealed and matched on the excircle of bellows, and when pipeline external surface was smooth, pipeline sealed through seal ring and interior seal groove; Also wear seal ring in the external sealed groove, be fixed as one through pouring mortar and Well-wall sealer.Backfill and trim the road surface after, when the manhole top, the inconsistent situation of sedimentation will appear in inspection shaft and backfill all around thereof as heavy duty; The sedimentation that is backfill and pipeline is greater than inspection shaft sedimentation size; But because the outer lower portion and the inside upper part of pipeline and inspection shaft borehole wall joint have flexible resilience part, flexible resilience part plays the good buffering and the effect of bit shift compensation, and greatly reduces the situation that stress is concentrated; After heavy duty; Under the effect of flexible resilience part, pipeline can restore to the original state, thus impaired situation when avoiding heavy duty.

Fig. 1 is the structural representation of the embodiment of the invention one;
Fig. 2 is the structural representation of the embodiment of the invention two.
Embodiment
Embodiment one: as shown in Figure 1; Piping displacement compensator of the present invention; Comprise sleeve pipe 2 with cylindrical cavity 1; Half-turn is provided with and is respectively equipped with flexible resilience part 3 and flexible resilience part 4 on sleeve pipe 2 one end lower branches and the other end, and the surface of flexible resilience part 3 and flexible resilience part 4 is equal with sleeve pipe 2 inwalls.Sleeve pipe 2 inwalls are provided with seal groove 5 at least one.Sleeve pipe 2 outer rings are provided with at least one external sealed groove 6.Seal groove 5 is equipped with twice with external sealed groove 6 in the present embodiment.
Carrying out under ground piping when laying, sleeve pipe 2 is preset in pipeline specified position that is installed in the inspection shaft borehole wall or the preformed hole that is installed in the borehole wall with the inspection shaft construction operation.The end that sleeve pipe 2 lower branches have a flexible resilience part 3 is positioned at the inspection shaft outside, and the end that half-turn has a flexible resilience part 4 on the sleeve pipe 2 is positioned at the inspection shaft inboard, and then pipeline is penetrated in the cylindrical cavity 1 of sleeve pipe 2 again; When pipeline is bellows; Ripple and interior seal groove 5 are sealed and matched on the excircle of bellows, and when pipeline external surface was smooth, pipeline sealed through seal ring and interior seal groove 5; Also wear seal ring in the external sealed groove 6, be fixed as one through pouring mortar and Well-wall sealer.Backfill and trim the road surface after, when the manhole top, the inconsistent situation of sedimentation will appear in inspection shaft and backfill all around thereof as heavy duty; The sedimentation that is backfill and pipeline is greater than inspection shaft sedimentation size; But because the outer lower portion of pipeline and inspection shaft borehole wall joint and inside upper part have flexible resilience part 3 and flexible resilience part 4 respectively, flexible resilience part 3 plays the good buffering and the effect of bit shift compensation with flexible resilience part 4, and greatly reduces the situation that stress is concentrated; After heavy duty; Under the effect of flexible resilience part 3 and flexible resilience part 4, pipeline can restore to the original state, thus impaired situation when avoiding heavy duty.
Embodiment two: as shown in Figure 2, be that with embodiment one difference one whole circle inboard, sleeve pipe 2 two end part is respectively equipped with flexible resilience part 3 and flexible resilience part 4, placement that so just can any direction when mounting sleeve 2.
Claims (3)
1. piping displacement compensator is characterized in that: comprise the sleeve pipe with cylindrical cavity, half-turn or sleeve pipe two end part one whole circle are provided with flexible resilience part on sleeve pipe one end lower branch and the other end, and flexible resilience part surface is equal with internal surface of sleeve pipe.
2. piping displacement compensator according to claim 1 is characterized in that: said internal surface of sleeve pipe is provided with seal groove at least one.
