Description

Technical Field

[0001] This utility model relates to the field of buried drainage pipe technology, and in particular to BFHDPP basalt double-wave thermal structure wall pipe. Background Technology

[0002] In recent years, my country has developed a new type of buried plastic drainage pipe that needs to withstand soil pressure and rainwater erosion, and can adapt to the bending requirements of complex installation environments. The steel strip spiral corrugated pipe combines the high rigidity and high strength of steel with the flexibility, corrosion resistance and wear resistance of the hot melt material by pressing continuous steel strips into approximately Λ-shaped spiral steel ribs and winding them between the inner and outer layers of hot melt material. It adopts hot melt extrusion welding and electrofusion strip connection methods, which better meet the sealing and connection requirements.

[0003] However, most existing steel strip pipes have single corrugated peaks with large and sparse peak spacing, resulting in poor compressive and impact resistance, low steel strip distortion, and insufficient stress strength, making it difficult to meet higher usage requirements.

[0004] Furthermore, existing corrugated spiral wound (Type B) pipes have defects in the application of large-diameter (greater than or equal to 1000mm) pipelines. They adopt a continuous spiral wound technology for circular pipes, and the strength of the trough area between the crests of the outer reinforcing ribs is relatively weak and is a stress concentration area. During transportation or construction, due to the low pressure bearing capacity, load resistance and toughness resistance of the trough area, it is difficult to meet the high ring stiffness (greater than 12.5KN) requirement, which can easily cause pipeline damage and reduce the performance and service life of the product.

[0005] Therefore, BFHDPP basalt double-wave thermal structural wall tubes are proposed. Utility Model Content

[0006] The purpose of this invention is to provide BFHDPP basalt double-wave hot-state structural wall pipe, which can solve the problems of existing steel strip pipes, which are mostly single-wave peaks with large and non-dense peak spacing, resulting in poor pressure resistance and impact resistance, low steel strip distortion, and insufficient stress strength, making it difficult to meet higher usage requirements.

[0007] To achieve the above objectives, the present invention provides the following technical solution: BFHDPP basalt double-wave hot-state structural wall pipe, comprising a pipe body, wherein large wave peaks are wound around the surface of the pipe body, and a wave trough area is formed between adjacent large wave peaks and the surface of the pipe body, and a number of uniformly distributed small wave peaks are wound around the surface of the wave trough area.

[0008] The main body of the pipe includes an outer wall pipe and an inner wall pipe, and a reinforcing layer is provided between the opposite sides of the outer wall pipe and the inner wall pipe.

[0009] Preferably, both the outer and inner wall tubes are made of polypropylene.

[0010] Preferably, the reinforcing layer is made of basalt material.

[0011] Preferably, the small peaks are distributed in a matrix in the trough area, the horizontal and vertical spacing between adjacent small peaks are equal, and the spacing between adjacent large peaks on the pipe body is equal.

[0012] Preferably, the small and large peaks are spirally wound around the trough area and the surface of the pipe body, respectively.

[0013] Preferably, the cross-section of the large wave peak is semi-elliptical and has a hollow internal structure.

[0014] Preferably, the small wave crests are arranged in a wave-like shape with respect to the axial cross-section of the pipe body.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application utilizes several uniformly distributed small peaks. When the pipeline is subjected to external pressure, the small peaks can disperse the pressure to the entire trough area and adjacent structures, avoiding excessive stress concentration in the trough area and significantly improving the pressure resistance of the trough area. Compared with the traditional single-peak structure, the matrix distribution of small peaks allows the pipeline to uniformly disperse stress when subjected to pressure or tension in all directions, enhancing the pipeline's impact resistance and reducing the risk of damage caused by excessive local stress. In addition, the combination of small peaks and large peaks changes the overall mechanical structure of the pipeline, optimizes the force transmission path, and enables the pipeline to more efficiently transmit force to the outer wall and reinforcement layer when subjected to complex external forces, thereby effectively improving the ring stiffness of the pipeline and enabling it to meet the requirements of high ring stiffness (greater than 12.5KN) and adapt to various harsh engineering conditions.

[0017] 2. This application utilizes a composite reinforcement layer in the main body of the pipe. When the pipe is subjected to soil pressure, collisions during transportation, and external forces during construction, the composite basalt material reinforcement layer can effectively resist deformation and damage, enhancing the pipe's load-bearing capacity. At the same time, basalt material also has good corrosion resistance, resisting the erosion of rainwater, acid and alkali substances in the soil, etc., extending the service life of the pipe, and solving the problem of short service life caused by poor corrosion resistance of traditional pipes.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 The present invention provides the following technical solution:

[0024] BFHDPP basalt double-wave hot structured wall pipe includes a pipe body 1, with large wave peaks 2 wound around the surface of the pipe body 1, and a wave trough area 3 formed between adjacent large wave peaks 2 and the pipe surface, and a number of evenly distributed small wave peaks 4 wound around the surface of the wave trough area 3.

[0025] The main body of the pipe 1 includes an outer wall pipe 5 and an inner wall pipe 6, and a reinforcing layer 7 is provided between the opposite sides of the outer wall pipe 5 and the inner wall pipe 6.

[0026] In this embodiment: through several uniformly distributed small peaks 4, when the pipeline is subjected to external pressure, the small peaks 4 can disperse the pressure to the entire trough area 3 and adjacent structures, avoiding excessive stress concentration in the trough area 3, and significantly improving the pressure resistance of the trough area 3. Compared with the traditional single-peak structure, the matrix distribution of the small peaks 4 allows the pipeline to uniformly disperse stress when subjected to pressure or tension from all directions, enhancing the pipeline's impact resistance and reducing the risk of damage due to excessive local stress. In addition, the small peaks 4, in conjunction with the large peaks 2, change the overall mechanical structure of the pipeline, optimize the force transmission path, and enable the pipeline to withstand complex external forces more effectively. The force is effectively transferred to the outer wall and the reinforcing layer 7, thereby effectively improving the ring stiffness of the pipeline and enabling it to meet the requirements of high ring stiffness (greater than 12.5KN) and adapt to various harsh engineering conditions. Through the composite reinforcing layer 7 of the main pipe 1, when the pipeline is subjected to soil pressure, collisions during transportation, and external forces during construction, the composite basalt material reinforcing layer 7 can effectively resist deformation and damage, enhance the load-bearing capacity of the pipeline. At the same time, basalt material also has good corrosion resistance, which can resist the erosion of rainwater, acid and alkali substances in the soil, etc., and extend the service life of the pipeline, solving the problem of short service life caused by poor corrosion resistance of traditional pipelines.

[0027] Specifically, such as Figure 3 As shown, both the outer tube 5 and the inner tube 6 are made of polypropylene.

[0028] Specifically, such as Figure 3 As shown, the reinforcing layer 7 is composed of basalt material.

[0029] In this embodiment: Polypropylene material has good flexibility, corrosion resistance, and wear resistance. Using polypropylene material for both the outer wall pipe 5 and the inner wall pipe 6 allows the pipe to adapt to complex and varied installation environments. It is less prone to breakage when subjected to bending, meeting installation requirements such as avoiding other underground lines. Simultaneously, its corrosion resistance effectively resists erosion from rainwater, extending the pipe's service life. Furthermore, its wear resistance helps reduce damage caused by friction during transportation and use, lowering maintenance costs and improving the pipe's reliability and stability. Basalt material has high strength and high modulus. Using it as the reinforcing layer 7 significantly enhances the overall strength and load-bearing capacity of the pipe. When the pipe is subjected to external pressure and tension, the basalt reinforcing layer 7 effectively disperses stress, improving the pipe's resistance to deformation and enabling it to withstand greater loads. In addition, basalt material also has good high-temperature resistance and corrosion resistance, improving the pipe's adaptability to harsh environments and further ensuring stable performance during long-term use, meeting the high strength and durability requirements of buried plastic drainage pipes.

[0030] Specifically, such as Figure 2 As shown, the small peaks 4 are distributed in a matrix on the trough area 3, and the horizontal and vertical spacing between adjacent small peaks 4 are equal, as are the spacing between adjacent large peaks 2 on the pipe body 1.

[0031] Specifically, such as Figure 2 As shown, small wave peak 4 and large wave peak 2 are spirally wrapped around the surface of wave trough area 3 and pipe body 1, respectively.

[0032] Specifically, such as Figure 2 As shown, the cross-section of the large wave peak 2 is set in a semi-elliptical shape and has a hollow internal structure.

[0033] In this embodiment: the matrix-like uniform distribution of small peaks 4 ensures the uniformity of stress dispersion in the trough region 3, making the pipe more evenly stressed in all directions, avoiding damage caused by local stress concentration, and greatly improving the compressive and impact resistance of the trough region 3. The equal spacing between adjacent large peaks 2 on the main body 1 of the pipe helps to form a stable mechanical structure, enabling the force to be evenly transmitted and distributed when the pipe is under pressure, further enhancing the overall stability and strength of the pipe, improving the ring stiffness of the pipe, and enabling it to better adapt to the load requirements under various engineering conditions. The semi-elliptical cross-section design of the large peaks 2 optimizes the stress distribution of the large peaks 2. Compared with other shapes, the semi-elliptical shape can more evenly disperse stress when under pressure, reduce stress concentration, and improve the compressive strength of the large peaks 2. The internal hollow structure reduces the overall weight of the pipe without reducing the strength of the large peaks 2, reducing transportation and construction costs. In addition, the hollow structure can also absorb and buffer external impact forces to a certain extent, further enhancing the impact resistance of the pipe.

[0034] Specifically, such as Figure 2 As shown, the small wave peak 4 and the axial section of the pipe body 1 are arranged in a wave-like shape.

[0035] In this embodiment, the wavy design of the small peaks 4 and the axial section of the pipe body 1 enables the pipe to have good flexibility and deformation capacity in the axial direction. When the pipe is subjected to axial tension or pressure, the wavy structure can absorb and disperse the force through its own deformation, avoiding breakage or damage caused by excessive rigidity. This design enhances the pipe's adaptability to complex environments, especially in situations where the pipe needs to be stretched or compressed to a certain extent. It can effectively protect the structural integrity of the pipe and further improve the pipe's fatigue resistance, extending the service life of the pipe.

[0036] Working Principle: When the main body 1 of the pipe is in use, several evenly distributed small peaks 4 disperse the pressure to the entire trough area 3 and adjacent structures when the pipe is subjected to external pressure. This prevents excessive stress concentration in the trough area 3 and significantly improves the pressure resistance of the trough area 3. Compared with the traditional single-peak structure, the matrix distribution of the small peaks 4 allows the pipe to evenly distribute stress when subjected to pressure or tension from all directions, enhancing the pipe's impact resistance and reducing the risk of breakage due to excessive local stress. In addition, the small peaks 4, in conjunction with the large peaks 2, change the overall mechanical structure of the pipe and optimize the force transmission path. This allows the pipe to more efficiently transmit force to the outer wall and reinforcing layer 7 when subjected to complex external forces, thereby effectively improving the pipe's ring stiffness and enabling it to meet the requirement of high ring stiffness (greater than 12.5KN). To meet the requirements of various harsh engineering conditions, the composite basalt material reinforcement layer 7 of the main pipe 1 effectively resists deformation and damage when the pipeline is subjected to soil pressure, collisions during transportation, and external forces during construction, enhancing the pipeline's load-bearing capacity. Simultaneously, basalt material has excellent corrosion resistance, resisting erosion from rainwater and acidic / alkaline substances in the soil, extending the pipeline's service life and solving the problem of short service life caused by poor corrosion resistance in traditional pipelines. Furthermore, the composite basalt material reinforcement layer 7, located between the inner and outer pipe walls 5, effectively disperses the stress on the inner and outer walls of the pipeline, making the stress distribution more uniform when the pipeline is subjected to external pressure or changes in internal fluid pressure, further improving the pipeline's stability and reliability, and meeting the needs of complex and ever-changing installation and usage environments.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
