Description

Technical Field

[0001] This invention belongs to the field of pipeline construction and anti-settlement technology. Specifically, it relates to a high-backfill outdoor anti-settlement rainwater and sewage pipeline and its construction method. Background Technology

[0002] With the acceleration of urbanization, the scarcity of urban land resources has become increasingly apparent, leading to the widespread application of backfill technology in underground pipeline engineering. In urban drainage systems, stormwater and sewage pipes are a crucial component, responsible for discharging rainwater and sewage from buildings or roads into the sewer system. However, due to the often complex geological conditions in underground pipeline projects, traditional backfilling methods often fail to meet the requirements of high quality, high strength, and settlement resistance.

[0003] Traditional pipeline backfilling methods typically use natural soil or gravel; however, this approach presents several problems. First, the weight of the pipeline has long caused uneven settlement of the surrounding soil, making the pipeline susceptible to deformation and rupture. Furthermore, the unevenness of urban geological conditions leads to uneven soil settlement, which exerts uneven pressure on the pipeline, increasing the risk of rupture and leakage. Second, natural soil has limited support capacity for pipelines, making it difficult to meet the long-term stability requirements of the project. Especially under complex geological conditions, the soil's support capacity may be insufficient to provide lasting support. Summary of the Invention

[0004] In view of this, the present invention provides a high-backfill outdoor anti-settlement rainwater and sewage pipeline and a construction method, which can strengthen the bottom support of the outdoor rainwater and sewage pipeline and prevent geological settlement from damaging the pipeline.

[0005] This invention is implemented as follows:

[0006] This invention provides a high-backfill outdoor anti-settlement rainwater and sewage pipeline, comprising multiple sets of rainwater and sewage pipes and an anti-settlement section. The rainwater and sewage pipes are connected and installed via connecting components. The anti-settlement section includes a support layer and a fixing plate. The support layer includes a bracket and sidewalls. The top of the bracket is fixedly connected to the support plate by bolts, and the bottom of the bracket is provided with a reinforcing anchor. A set of sidewalls is provided on both the left and right sides of the support plate, with multiple sets of reinforcing holes arranged on the sidewalls. Reinforcing anchor pipes are installed inside the reinforcing holes. A fixing block is provided at the bottom of the fixing plate, and an insert block adapted to the fixing block is provided at the top of the support plate. The fixing block and the insert block are fixedly connected by bolts.

[0007] The technical effects of the high-backfill outdoor anti-settlement rainwater and sewage pipeline provided by the present invention are as follows: by setting up multiple sets of rainwater and sewage pipes and connecting and fixing them through connecting components, a complete rainwater and sewage pipeline is formed; by setting up multiple sets of anti-settlement parts to support each set of rainwater and sewage pipes respectively, and by setting up brackets and support plates to achieve the effect of support and fixation; by setting up side wall plates, reinforcement holes and reinforcement anchor pipes to work with lightweight backfill layers to achieve the effect of reinforcement and anti-settlement.

[0008] Based on the above technical solution, the high backfill outdoor anti-settlement rainwater and sewage pipeline of the present invention can be further improved as follows:

[0009] The support layer further includes a lightweight backfill layer, which is disposed on the top of the support plate and inside the reinforcing anchor pipe. One end of the reinforcing anchor pipe is fixed to the reinforcing hole via a detachable component.

[0010] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a lightweight backfill layer as the backfill material for filling and reinforcing the inside of the anchor pipe and the top of the support plate, it is used to fill the gaps and helps to reduce the weight of the soil and prevent the support from settling downward.

[0011] Furthermore, the fixing plate has an arc-shaped structure, and the inner wall size of the fixing plate is adapted to the outer diameter of the rainwater and sewage pipe. The fixing plate is used to support and place the rainwater and sewage pipe. The connecting assembly includes a pipe connector, and each end of the pipe connector is provided with a clamping head. The inner diameter of the clamping head is adapted to the outer diameter of both ends of the anti-settlement part. The clamping head is used to connect and fix two adjacent sets of rainwater and sewage pipes by the pipe connector.

[0012] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting clamping joints to clamp and fix the two ends of the rainwater and sewage pipes, and by setting pipe connectors to clamp and fix two adjacent sets of rainwater and sewage pipes, a complete rainwater and sewage pipe system is constructed.

[0013] Furthermore, the snap-fit ​​connector has a fastening channel inside, and a fastening band is provided inside the fastening channel. One end of the fastening band is fixedly connected to the fastening channel, and the other end of the fastening band extends through to the outside of the fastening channel and is rotatably connected to the adjusting bolt via a rotating shaft. One end of the adjusting bolt has a threaded structure on its outer wall, and the snap-fit ​​connector has a threaded hole corresponding to the position of the adjusting bolt that matches the adjusting bolt. The adjusting bolt is adjustablely connected to the threaded hole.

[0014] Furthermore, an adjusting handle is provided in the middle of the adjusting bolt, the adjusting handle is fixedly connected to the adjusting bolt, and a rotating shaft is provided at the other end of the adjusting bolt. The rotating shaft is rotatably connected to the rotating shaft through a rotating groove, and the rotating shaft is fixedly connected to one end of the fastening band that extends outward.

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting up a fastening channel, the fastening band inside the fastening channel can play a role in tightening and reinforcing. By making one end of the fastening band rotate and connected to the adjusting bolt through the rotating shaft, when the rotating adjusting handle drives the adjusting bolt to adjust outward, it drives the fastening band to tighten, thereby achieving the fastening effect.

[0016] Furthermore, the detachable component includes a mounting base and a slot. The slot is formed on the inner wall of the side wall panel facing the support plate. The mounting base is provided on the reinforcing anchor pipe at the position corresponding to the slot. The mounting base is used to install and fix the reinforcing anchor pipe at the position corresponding to the slot.

[0017] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting the card seat and card slot, it is convenient to install and fix the reinforced anchor pipe, and it is convenient to grout the inside of the reinforced anchor pipe. By setting the reinforced anchor pipe and the lightweight backfill layer, it is used to disperse the pressure to the surrounding soil and prevent geological settlement.

[0018] This invention provides a construction method for high-backfill outdoor anti-settlement rainwater and sewage pipelines, comprising the following steps:

[0019] S10: Measure and mark the laying path according to the design, and dig trenches for pipe laying according to the marked path;

[0026] Step 3: After the trench for pipe laying is excavated, the inner surface of the trench needs to be leveled, and the substrate is backfilled and then gradually compacted to restore the surface to a smooth state.

[0027] Furthermore, the specific steps of installing a support layer inside the pipe-laying trench and fixing a fixing plate on top of the support plate include:

[0028] Step 1: First, erect supports in the pipe-laying trench, ensuring that the reinforcing anchors at the bottom of the supports penetrate deep into the bottom of the trench.

[0029] Step 2: Fix the support plate on the upper end of the bracket through the corresponding bolt holes, so that the side walls on both sides of the support plate are in contact with the side walls of the pipe trench.

[0030] Step 3: Make holes directly into the side walls of the pipe-laying trench on both sides at the locations of the reinforcement holes on the corresponding side wall panels;

[0031] Step 4: After the hole is opened, insert one end of the reinforcing anchor pipe into the hole and fix the other end of the anchor pipe to the corresponding slot on the side wall.

[0032] Step 5: After installation, inject aerated concrete into the reinforced anchor pipe and pour aerated concrete onto the top of the support plate. Note that the pouring position should be lower than the screw hole position of the top insert block of the support plate to construct a lightweight backfill layer.

[0033] Step 6: After the aerated concrete has solidified and dried completely, install the fixing plate onto the top of the support plate using fixing bolts.

[0034] Furthermore, the specific steps for placing the rainwater and sewage pipes on the fixing plate and installing and fixing them using connecting components include:

[0035] Step 1: Place the rainwater and sewage pipes on the fixing plate, making sure the pipes are partially surrounded by the fixing plate, and secure them with straps;

[0036] Step 2: Connect the clamp at one end of the pipe connector to one end of the storm and sewage pipe, and then connect the clamp at the other end of the pipe connector to one end of the adjacent storm and sewage pipe to secure it.

[0037] Step 3: By rotating the adjusting handle on one side of the clamp connector, tighten the fastening tape to seal and fix the connection end of the rainwater and sewage pipe, thus forming a complete rainwater and sewage pipeline.
