Description

Technical Field

[0001] This utility model relates to the field of municipal engineering protection technology, specifically a trench excavation underground pipeline anti-settlement limit protection device. Background Technology

[0002] Underground pipelines in municipal engineering are the "blood vessels" of urban infrastructure, encompassing various types such as water supply, drainage, gas, heating, electricity, and communications. They are mostly buried under roads and connect different areas of the city through complex pipeline networks. The materials are selected according to their functions; for example, ductile iron pipes and PE pipes are often used for water supply, while concrete pipes and HDPE corrugated pipes are commonly used for drainage. Construction must take into account geological conditions and surrounding facilities to ensure pressure resistance and leak prevention. Regular inspection and maintenance are required to prevent problems such as cracking and blockage. They ensure the normal operation of the city and are an important support for residents' lives, industrial production, and ecological environmental protection.

[0003] In existing underground pipeline protection technologies, such as the underground pipeline protection device with application number 202421523860.9, the technical solution includes a trench and a protective sleeve: the pipeline body is sleeved inside the protective sleeve; the upper and lower ends of the protective sleeve are provided with a first filling groove and a second filling groove, and the connection between the first filling groove and the second filling groove is an arc-shaped opening that matches the protective sleeve; the upper end of the first filling groove is provided with a filling port, and the upper end of the filling port is provided with a filling box; baffles are fixedly connected to both ends of the fixing head; however, in the excavation and construction of underground pipeline trenches, pipeline settlement and displacement are common hidden dangers. Traditional construction often uses simple protection methods such as sandbag stacking and steel plate support, which makes it difficult to accurately control the pipeline posture. When the trench is excavated, the unloading of the soil can easily cause stress reshaping of the surrounding strata, resulting in vertical settlement and lateral displacement of the pipeline. Especially in soft soil areas or areas near existing buildings, settlement may cause cracks and breaks in the pipeline interfaces, leading to safety accidents such as water leakage and gas leakage.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was developed based on existing underground pipeline protection devices. Utility Model Content

[0006] The purpose of this utility model is to provide a settlement-limiting protection device for underground pipelines in trench excavation, so as to solve the problem of pipeline settlement and displacement mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A trench excavation underground pipeline anti-settlement limiting protection device includes an underground layer, a water supply pipeline, and a protective support. The underground layer has a trench excavated inside, and the water supply pipeline is installed horizontally inside the trench. The protective support is fixedly installed on the upper surface of the trench in the underground layer. Two horizontal frames are bolted to the upper surface of the protective support, and a support column is connected to the lower part of the protective support. Reinforcing supports are connected to the front and rear sides of the horizontal frames. Several slings are provided below the horizontal frames, and a first hook is provided above the slings, and a second hook is provided at the bottom of the slings. The water supply pipeline is installed below the slings.

[0009] Preferably, the protective support is fixedly connected to the front and rear sides of the bottom, and the support is located on the left and right sides of the trench in the underground layer.

[0010] Using the above technical solution, the support columns at the front and rear sides of the bottom of the protective support are distributed on the left and right sides of the trench, providing vertical support for the overall structure, and evenly transferring the load of the protective support to the underground layer, avoiding the collapse caused by the concentration of force on the soil at the edge of the trench, and ensuring the installation stability of the water supply pipeline.

[0011] Preferably, the angle between the reinforcing bracket and the protective bracket is 45°, and the reinforcing bracket is fixedly connected to the protective bracket and the crossbar by bolts.

[0012] By adopting the above technical solution, the reinforced support and the protective support are at a 45° angle and are fixedly connected to the cross frame by bolts to form a triangular stable structure. This can effectively resist the lateral soil pressure during trench excavation, reduce the lateral deformation of the protective support, and prevent the water supply pipeline from shifting due to structural shaking.

[0013] Preferably, each of the crossbars is provided with several support rods, and the first hook is hung in the middle of the support rod, the bottom of the second hook is hung on the fixing ring, and the fixing ring is installed on the outside of the water supply pipe.

[0014] Using the above technical solution, the support rods between the crossbeams provide multiple suspension points for the first hook, which, together with the second hook and the fixing ring on the outside of the water supply pipeline, form a "hanging above and fixing below" limiting structure, which can accurately constrain the vertical settlement of the pipeline and improve the settlement control accuracy compared with traditional sandbag loading.

[0015] Preferably, a plurality of vertical frames are provided between the two horizontal frames on the upper surface of the protective bracket, and the vertical frames are perpendicular to the horizontal frames.

[0016] By adopting the above technical solution, the vertical crossbars between the two crossbars form a grid structure, which enhances the overall rigidity of the crossbars and avoids the bending of the crossbars caused by uneven stress on the slings. At the same time, the grid structure can distribute the load of the water supply pipeline and meet the protection requirements of long-distance pipelines.

[0017] Preferably, each of the crossbeams is equipped with a sling, and both the front and rear slings are fitted with pads at their bottoms.

[0018] Using the above technical solution, the slings under the crossbeam contact the water supply pipeline through the pads. The pads increase the stress-bearing area, disperse the concentrated stress of the slings, and prevent the pipeline surface from being damaged due to local pressure. This is especially suitable for water supply pipelines made of brittle materials such as PE.

[0019] Preferably, I-beam support plates are fixedly installed on the front and rear sides of the upper surface of the pad, and water supply pipes are installed above the front and rear I-beam support plates.

[0020] Using the above technical solution, the I-beam support plate on the upper surface of the pad forms a groove structure, in which the water supply pipeline is embedded to achieve lateral restraint. Combined with the vertical restraint of the sling, a three-dimensional restraint is formed, which can simultaneously resist vertical settlement and lateral displacement during trench excavation, thus improving pipeline stability compared to traditional protection methods.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the anti-settlement limiting protection device for underground pipelines during trench excavation,

[0022] 1. Multi-dimensional limiting structure for precise control of pipeline settlement and displacement: The slings and hooks form a vertical suspension system, the I-beam support plate forms a lateral constraint, and the triangular reinforcement structure resists lateral forces, realizing three-dimensional limiting of the water supply pipeline. Compared with the traditional protection method, the comprehensive displacement control accuracy is improved, which can effectively avoid pipeline interface cracking.

[0023] 2. Modular and stable structure, suitable for complex trench environments: The combination of pillars, reinforced supports, and grid-like horizontal and vertical frames forms a modular support system with a load-bearing capacity of ≥50kN and a lateral force resistance of ≥20kN / m. It is suitable for complex environments such as soft soil areas and narrow trenches. The installation efficiency is improved compared to traditional steel plate supports, and the reuse rate is increased. Attached Figure Description

Example 1

[0032] Please see Figure 1-4 This utility model provides a technical solution:

[0033] A trench excavation underground pipeline anti-settlement limiting protection device includes an underground layer 1, a water supply pipeline 2, and a protective support 3. A trench is excavated inside the underground layer 1, and the water supply pipeline 2 is installed horizontally inside the trench. The protective support 3 is fixedly installed on the upper surface of the trench in the underground layer 1. Two horizontal frames 5 are bolted to the upper surface of the protective support 3, and a support column 4 is connected to the lower part of the protective support 3. The front and rear sides of the horizontal frames 5 are connected to the protective support 3 with reinforcing supports 6. Several slings 9 are set below the horizontal frames 5, and a first hook 8 is set above the slings 9, and a second hook 10 is set at the bottom of the slings 9. The water supply pipeline 2 is installed below the slings 9.

[0034] The protective support 3 is fixedly connected to the front and rear sides of the bottom with support columns 4, and the support columns 4 are located on the left and right sides of the trench in the underground layer 1. The reinforcing support 6 is at a 45° angle with the protective support 3, and the reinforcing support 6 is fixedly connected to the protective support 3 and the cross frame 5 by bolts. The support columns 4 on the front and rear sides of the bottom of the protective support 3 are distributed on the left and right sides of the trench, providing vertical support for the overall structure and evenly transferring the load of the protective support 3 to the underground layer 1, avoiding the collapse caused by the concentration of force on the soil at the edge of the trench, and ensuring the installation stability of the water supply pipeline 2. The reinforcing support 6 is at a 45° angle with the protective support 3 and is fixedly connected to the cross frame 5 by bolts to form a triangular stable structure, which can effectively resist the lateral soil pressure during trench excavation, reduce the lateral deformation of the protective support 3, and prevent the water supply pipeline 2 from displaced due to structural shaking.

[0035] Several support rods 7 are provided between the crossbeams 5, and the first hook 8 is hung in the middle of the support rod 7. The bottom of the second hook 10 is hung on the fixing ring 11, and the fixing ring 11 is installed on the outside of the water supply pipe 2. The support rods 7 between the crossbeams 5 provide multiple suspension points for the first hook 8. Together with the second hook 10 and the fixing ring 11 on the outside of the water supply pipe 2, a "hanging on top and fixing on the bottom" limiting structure is formed, which can accurately constrain the vertical settlement of the pipeline and improve the settlement control accuracy compared with traditional sandbag loading. Example 2

[0036] Please see Figure 5-6 This utility model provides a technical solution:

[0037] Several vertical frames 12 are arranged between the two horizontal frames 5 on the upper surface of the protective bracket 3, and the vertical frames 12 are perpendicular to the horizontal frames 5. Each horizontal frame 5 is equipped with a sling 9, and a pad 13 is installed at the bottom of each of the front and rear slings 9. I-beam support plates 14 are fixedly installed on the front and rear sides of the upper surface of the pad 13, and a water supply pipe 2 is installed above the front and rear I-beam support plates 14. The vertical frames 12 between the two horizontal frames 5 intersect perpendicularly to form a grid structure, which enhances the overall rigidity of the horizontal frames 5 and prevents bending of the horizontal frames 5 due to uneven stress on the slings 9. At the same time, the grid structure can distribute the load on the water supply pipe 2. The system is designed to meet the protection needs of long-distance pipelines. The sling 9 under the crossbeam 5 contacts the water supply pipeline 2 through the pad 13. The pad 13 increases the stress-bearing area and disperses the concentrated stress of the sling 9, preventing damage to the pipeline surface due to local pressure. It is especially suitable for water supply pipelines 2 made of brittle materials such as PE. The I-beam support plate 14 on the upper surface of the pad 13 forms a groove structure in which the water supply pipeline 2 is embedded to achieve lateral restraint. Combined with the vertical restraint of the sling 9, it forms a three-dimensional restraint, which can resist vertical settlement and lateral displacement during trench excavation, thus improving pipeline stability compared to traditional protection methods.
