Problems solved by technology

[0002] During the road construction process, underground pipeline laying and inspection well construction operations are required. The well wall of the inspection well is provided with a reserved hole for passing through the pipeline. The joint between the outer wall of the laid pipeline and the reserved hole on the well wall is a rigid connection. When carrying a car, the settlement of the backfill soil around the inspection well and its surroundings will be inconsistent, that is, the settlement of the backfill soil and the pipe is greater than the settlement size of the inspection well, and there is stress concentration at the joint between the outer wall of the pipe and the well wall of the inspection well, especially for plastic pipes. rupture, resulting in water leakage
This phenomenon is more serious when the backfill operation is not standardized, therefore, it is urgent to solve the above-mentioned problems existing in the prior art

Embodiment 1

[0013] Embodiment one: if figure 1 As shown, the elastic displacement compensator of the present invention includes a sleeve 2 with a cylindrical cavity 1, the sleeve 2 is made of an elastic flexible material, and several rigid joints coaxial with the sleeve 2 are arranged in the sleeve 2. Reinforcing ring 3. The inner wall of the casing 2 is provided with at least one inner sealing ring 5 . The outer ring of the casing 2 is provided with at least one anti-seepage groove 6 and / or a convex anti-seepage sealing ring 7 . In this embodiment, three inner sealing rings 5 ​​are arranged, one of which is arranged on the outermost side of the casing 2 and the inspection shaft; two anti-seepage grooves 6 are arranged. The truncated surface of the inner sealing ring 5 is an isosceles acute triangle.

[0014] During underground pipeline laying and inspection well construction operations, the casing 2 is pre-installed at the designated position of the pipeline on the well wall of the in...

Embodiment 2

[0015] Embodiment two: if figure 2 As shown, the difference from the first embodiment is that a helical rigid rib 4 coaxial with the sleeve 2 is provided inside the sleeve 2 .

Embodiment 3

[0016] Embodiment three: as image 3 As shown, the difference from Embodiment 1 is that the lower semicircle of the outer wall at one end of the casing 2 is outwardly in the shape of a trumpet radially, which provides a large downward space for the pipeline, and expands the stressed section of the pipeline to the maximum without deformation. The larger the stress surface is, the greater the force will be, thereby reducing the effect of the pressure; the outer part of the semicircle on the inner wall of the other end of the casing 2 is in the shape of a horn radially, providing a free displacement space for the inner side of the inspection well of the pipe, thereby preventing the upper part of the pipe from being displaced due to upward displacement. Force problem.

Abstract

The invention discloses an elastic displacement compensator, comprising a sleeve with a cylindrical cavity, wherein the sleeve is made of an elastic flexible material; a rigid strengthening ring or a spiral rigid strengthening rib coaxial with the sleeve is arranged in the sleeve. After soil is backfilled and the pavement is improved, when a heavy load passes through the top of an inspection well, the backfill soil of the inspection well and the backfill soil at the four sides thereof may be settled differently; in other words, the settlement of the backfill soil and the pipeline is greater than that of the inspection well in size; however, as the sleeve is made of the elastic material, the sleeve functions well in buffering and displacement compensation and greatly reduces stress concentration; and after the heavy load passes away, the pipeline is capable of restoring to the original state under the resilience action of the sleeve; therefore, damage caused by the heavy load is avoided.

Description

technical field [0001] The invention belongs to the technical field of pipeline laying, in particular to an elastic displacement compensator. Background technique [0002] During the road construction process, underground pipeline laying and inspection well construction operations are required. The well wall of the inspection well is provided with a reserved hole for passing through the pipeline. The joint between the outer wall of the laid pipeline and the reserved hole on the well wall is a rigid connection. When carrying a car, the settlement of the backfill soil around the inspection well and its surroundings will be inconsistent, that is, the settlement of the backfill soil and the pipe is greater than the settlement size of the inspection well, and there is stress concentration at the joint between the outer wall of the pipe and the well wall of the inspection well, especially for plastic pipes. rupture, resulting in water leakage. This phenomenon is more serious when...
