[0002] In municipal engineering, in order to ensure the distribution of water supply, drainage, heating, gas supply and other materials, they are generally transported through underground pipelines. However, due to the large amount of backfill soil when laying underground pipelines in municipal engineering, the soil is prone to settlement, which makes the underground pipelines bear a large vertical load, causing settlement or even dislocation and deformation. Therefore, anti-settlement devices for underground pipelines are often needed.

[0003] At present, in order to avoid damage to underground pipelines caused by excessive settlement differences, a Chinese patent with publication number CN217081649U discloses an anti-settlement construction auxiliary device for underground pipelines in municipal road construction, including a cement base, a plurality of limit plates are fixedly connected to the top of the cement base, and the plurality of limit plates are evenly and symmetrically distributed, and two anti-settlement components are fixedly connected to the top of the cement base, and the two anti-settlement components are symmetrically distributed.

[0004] Although the prior art can reduce the contact between the pipeline and the backfill soil through the anti-settling component, so that even if the backfill soil settles, it will not cause the pipeline to sink downwards at the first time, it still cannot solve the problem that the backfill soil easily causes the pipeline to sink.

[0005] To this end, the present application proposes an underground pipeline anti-settling device for municipal engineering to solve the above technical problems. Utility Model Content

[0006] The purpose of the utility model is to address the deficiencies in the prior art and to provide an underground pipeline anti-settling device for municipal engineering, which can not only support the municipal pipeline to reduce the deformation effect of backfill soil sinking on the municipal pipeline, but also facilitate grouting reinforcement of the backfill soil, thereby further reducing the sinking of the municipal pipeline, and the overall use effect is good.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] An underground pipeline anti-settling device for municipal engineering comprises a base, wherein two support columns are symmetrically fixed to the upper end surface of the base, a vertical positioning column is constructed at the top end of the support column, a support plate is commonly sleeved between the two positioning columns, and a conduit is inserted at the top end of the positioning column, the support column, the positioning column and the conduit are hollow inside, a grouting cavity connected to the bottom end of the support column is opened in the base, and a plurality of grouting holes are opened on the bottom surface of the grouting cavity to expose the lower end surface of the base.

[0009] As a further preferred solution, the support plate is a concave semicircular frame, and a rubber pad is installed on the upper end surface of the support plate.

[0010] As a further preferred solution, the outer diameter of the positioning column is smaller than that of the supporting column, and a collar is fixed to the end of the supporting plate, the collar is sleeved on the positioning column and placed on the top of the supporting column.

[0011] As a further preferred solution, a positioning ring is sleeved on the positioning column, a fastening hole is opened on the side of the positioning ring, and a fastening bolt is arranged in the fastening hole.

[0012] As a further preferred solution, the fastening bolt threadably passes through the fastening hole and abuts against the surface of the positioning column to be fixed.

[0013] As a further preferred solution, the top end of the catheter is provided with an opening, and the opening is equipped with a sealing plug.

[0014] As a further preferred solution, a plurality of fastening cones for inserting into the ground are fixed to the lower end surface of the base, and the fastening cones are spaced apart from the grouting holes.

[0015] The beneficial effects of the utility model are:

[0016] 1) The utility model benefits from the cooperation of the base, support column, positioning column, support plate and positioning ring. The support plate can be erected on the base, and the support plate can be used to support the installed municipal pipeline to avoid direct contact between the municipal pipeline and the backfill soil, which is beneficial to reduce the deformation effect of the backfill soil sinking on the municipal pipeline to a certain extent.

[0017] 2) Thanks to the coordination of the support column, the positioning column, the conduit and the grouting chamber, the utility model can facilitate the workers to inject mortar into the backfill soil through the conduit and the grouting chamber when installing the pipeline. By reinforcing the backfill soil, the sinking problem of the installed municipal pipeline caused by the backfill soil can be further reduced.
