Description

Technical Field

[0001] The utility model relates to the technical field of pipeline construction, in particular to a high groundwater level pipeline trench backfill structure. Background Art

[0002] The pipeline is buried underground to avoid interference with ground facilities, so that farmland cultivation on the ground is not affected, roads can remain unobstructed, and rivers and channels can flow normally. High groundwater level refers to the high water level in the underground aquifer. At present, pipelines are mostly buried in trenches with high groundwater levels by backfilling.

[0003] During use, the pipeline is easily subjected to downward loads from the ground, and the backfill structure in the trench is simple, which makes it easy for the load on the ground to act directly on the pipeline, that is, the deformation of the road surface will be transmitted to the pipeline, causing the pipeline to be squeezed and deformed or even ruptured during long-term use, thereby affecting the safe transportation of the medium in the pipeline. Therefore, a high groundwater level pipeline trench backfill structure is proposed to solve the above problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a high groundwater level pipeline trench backfill structure, which has the advantages of improving the stability of backfill support and solves the problem of poor backfill support stability.

[0007] Furthermore, the two first support blocks and the second support blocks are symmetrically distributed on the outside of the tube body, and the two first support blocks and the second support blocks are provided with arc grooves at one end close to the tube body.

[0008] Furthermore, first connecting grooves are formed on the inner sides of the two first supporting blocks, and the specifications of the first connecting grooves are matched with the specifications of the first baffle.

[0009] Furthermore, a second connecting groove is formed on the inner sides of the two second supporting blocks, and the specification of the second connecting groove is matched with the specification of the second baffle.

[0010] Furthermore, a retaining groove is provided on the outer side of the second supporting block, and the specification of the retaining groove is matched with the specification of the side plate.

[0011] Furthermore, the filling bin is composed of a base layer, a first supporting layer, a second supporting layer reinforcement layer and a road base layer, the first supporting layer is filled at the upper end of the base layer, the second supporting layer is filled at the upper end of the first supporting layer, the reinforcement layer is filled at the upper end of the second supporting layer, and the road base layer is filled at the upper end of the second supporting layer.

[0012] Furthermore, the base layer is a crushed stone layer, the first supporting layer is a fine sand layer, and the second supporting layer is a coarse sand layer.

[0013] Furthermore, the reinforcement layer is a lime layer, and the road base layer is an asphalt concrete layer.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-2 In this embodiment, a high groundwater level pipeline trench backfill structure includes a filler layer 1, a support member 2 is placed inside the filler layer 1, and a pipe body 3 is placed inside the support member 2;

[0022] The filling bin 1 is composed of a base layer 11, a first supporting layer 12, a second supporting layer 13, a reinforcement layer 14 and a road base layer 15. The first supporting layer 12 is filled at the upper end of the base layer 11, the second supporting layer 13 is filled at the upper end of the first supporting layer 12, the reinforcement layer 14 is filled at the upper end of the second supporting layer 13, and the road base layer 15 is filled at the upper end of the second supporting layer 14.

[0023] The base layer 11 is a crushed stone layer, the first supporting layer 12 is a fine sand layer, the second supporting layer 13 is a coarse sand layer, the reinforcement layer 14 is a lime layer, and the road base layer 15 is an asphalt concrete layer.

[0024] In this embodiment, since the reinforcement layer 14 is a lime layer, the first support layer 12 is a fine sand layer, and the second support layer 13 is a coarse sand layer, the first support block 21 and the second support block 24 can be stably supported.

[0025] See also Figure 2-3 In this embodiment, the support member 2 includes two first support blocks 21 placed on the outside of the tube body 3, the inner sides of the two support blocks 21 are fixedly connected with a first baffle 22, the lower ends of the first support blocks 21 are provided with two second support blocks 24 located on the outside of the tube body 3, the inner sides of the two second support blocks 24 are fixedly connected with a second baffle 25, and the lower ends of the first support blocks 22 are fixedly connected with a side plate 23 having one end extending to the inside of the second support blocks 24.

[0026] In this embodiment, the first support block 21 and the second support block 24 placed on the outside of the tube body 3 can enclose and support the tube body 3, thereby reducing the deformation amount transmitted to the tube body 3 when the road surface is squeezed, and improving the support stability and protection of the tube body 3. Since the first support block 21 and the second support block 24 can be adjusted laterally and longitudinally, they can adapt to tube bodies 3 of different specifications to improve the adaptability of the entire backfill structure.

[0027] Among them, the two first support blocks 21 and the second support blocks 24 are symmetrically distributed on the outside of the tube body 3, and the two first support blocks 21 and the second support blocks 24 are provided with arc grooves 27 at one end close to the tube body 3, and the tube body 3 is supported by the arc grooves 27 on the first support blocks 21 and the second support blocks 24.

[0028] In addition, first connecting grooves 26 are provided on the inner sides of the two first support blocks 21, and the specifications of the first connecting grooves 26 are adapted to the specifications of the first baffle plate 22, so that when the two first support blocks 21 are adjusted laterally, they can be limited by the first baffle plate 22, and the filler can be blocked by the first baffle plate 22.

[0029] Secondly, the inner sides of the two second support blocks 24 are each provided with a second connecting groove 29, the specifications of which are compatible with the specifications of the second baffle plate 25, so that when the second support block 24 is adjusted laterally, it can be limited by the second baffle plate 25, and the filler can be blocked by the second baffle plate 25.

[0031] It should be noted that after the first support layer 12, the second support layer 13 and the reinforcement layer 14 are laid and space is left for placing the first support block 21 and the second support block 24, the second support block 24, the tube body 3 and the first support block 21 can be placed in sequence, and the sides of the first support block 21 and the second support block 24 are inclined, so that the sides of the support block 21 and the second support block 24 can be supported by the first support layer 12, the second support layer 13 and the reinforcement layer 14.

[0032] The working principle of the above embodiment is:

[0033] Since the reinforcement layer 14 is a lime layer, the first support layer 12 is a fine sand layer, and the second support layer 13 is a coarse sand layer, the first support block 21 and the second support block 24 can be stably supported, and the first support block 21 and the second support block 24 placed on the outside of the pipe body 3 can surround and support the pipe body 3, thereby reducing the deformation amount transmitted to the pipe body 3 when the road surface is squeezed, and improving the support stability and protection of the pipe body 3. Since the first support block 21 and the second support block 24 can be adjusted laterally and longitudinally, they can adapt to pipe bodies 3 of different specifications to improve the adaptability of the entire backfill structure.
