Description

Technical Field

[0001] This utility model relates to the field of pipe technology, specifically to a drainage pipe with a tension fiber structure. Background Technology

[0002] With the acceleration of urbanization and the continuous improvement of infrastructure, drainage systems, as a crucial part of urban operation, are receiving increasing attention for improving their performance and efficiency. Traditional drainage pipe materials, such as cement pipes, while meeting drainage needs to a certain extent, have many shortcomings in terms of environmental protection, energy conservation, and durability.

[0003] In recent years, with the advancement of materials science, new drainage pipe materials have emerged continuously, such as composite material pipes and fiber-reinforced pipes. These new materials have significant advantages in terms of strength, corrosion resistance, and environmental friendliness, and are gradually becoming the mainstream choice in the drainage pipe industry. For example, Chinese utility model patent application number 202222403054.5 discloses an HDPE plastic-steel reinforced PP skeleton spiral pipe, which includes an HDPE spiral pipe body formed by overlapping and winding plastic strips, and also includes: reinforcing components for improving the structural strength of the HDPE spiral pipe body. Several reinforcing components are equidistantly arranged on the HDPE spiral pipe body. This structure enhances the structural strength of the spiral pipe by setting anti-compression components on the HDPE spiral pipe body to prevent deformation of the HDPE spiral pipe body.

[0004] However, in the above structure, the pressure-resistant components include a steel plate and a limiting groove for accommodating the steel plate. Since both sides of the steel plate are bent outward to form limiting hooks, the limiting hooks need to be engaged in the inner cavity of the limiting groove to form a limit. Therefore, the steel plate needs to be bent in advance to form the corresponding structure during assembly, and then the steel plate is engaged in the limiting groove. This installation method is relatively troublesome, difficult to operate and install, and can easily damage the pipe body, increasing the installation cost. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a drainage pipe with a tensioned fiber structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A drain pipe with a tension fiber structure includes a pipe wall profile, which extends spirally along the cross-sectional direction and is wound sequentially to form a drain pipe body. The pipe wall profile has fastening structures on both sides for interlocking after sequential spiral winding. The pipe wall profile also has a tension fiber structure for improving the bending strength and ring stiffness of the pipe body. The tension fiber structure includes multiple mounting grooves on the outside of the pipe wall profile and tension fiber plates fitted into the mounting grooves. The tension fiber plates are filled into the mounting grooves by casting and are formed into a clamped structure after cooling and solidification.

[0008] Furthermore, the tensioned fiberboard is made of fiberglass.

[0009] In this utility model, the tensioning fiber structure is provided in two sets on the pipe wall profile, and the two sets of tensioning fiber structures are arranged at intervals, with the interval distance being 1 / 5 of the length of the pipe wall profile; the top surface of the tensioning fiber board is flush with the outer surface of the pipe wall profile.

[0010] In this utility model, the mounting groove is provided with a limiting groove, and there are two sets of limiting grooves. The two sets of limiting grooves are located on the left and right sides of the bottom of the mounting groove, respectively. The tensioned fiberboard has downward protruding limiting parts on both sides, and the limiting parts extend into the limiting groove to form a limit.

[0011] Furthermore, the width of the limiting groove gradually decreases from bottom to top, thus forming a tapered section at the groove opening.

[0012] Furthermore, a reinforcing groove is provided in the mounting groove between the two sets of limiting grooves, and a reinforcing part protrudes downward from the middle of the tensioned fiberboard, the reinforcing part extending into the reinforcing groove to form a pressing force.

[0013] Furthermore, the reinforcing groove forms a buckle with the limiting grooves on both sides, and the limiting parts on both sides of the tensioned fiberboard are laterally tightened by the two buckles.

[0014] This utility model has the following advantages and beneficial effects:

[0015] The tensioned fiberboard is filled into the mounting groove by casting and then cooled and solidified to form a clamp. The tensioned fiberboard made of fiberglass can perfectly fill the mounting groove to form a clamp without damaging the pipe structure, ensuring structural integrity and improving the connection strength between the tensioned fiberboard and the mounting groove. In addition, fiberglass has high impact resistance and compressive strength, and can withstand greater external pressure without being easily damaged, thus improving the bending strength and ring stiffness of the pipeline.

However, this utility model is not limited to the following embodiments.

[0021] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0023] like Figures 1 to 3As shown, this embodiment discloses a drainage pipe with a tension fiber structure, including a pipe wall profile 1. The pipe wall profile 1 extends spirally along the cross-sectional direction and is wound sequentially to form a drainage pipe body. The two sides of the pipe wall profile 1 are provided with a fastening structure 11 for sequential winding and interlocking connection. The pipe wall profile 1 is also provided with a tension fiber structure 12 for improving the bending strength and ring stiffness of the pipe body. The tension fiber structure 12 includes a plurality of mounting grooves 120 disposed on the outside of the pipe wall profile 1 and tension fiber plates 121 clamped in the mounting grooves 120. The tension fiber plates 121 are filled into the mounting grooves 120 by casting and are clamped after cooling and solidification. The tension fiber plates 121 are preferably made of fiberglass. Compared to the traditional method of clamping with steel plates, the tension fiberboard 121 made of fiberglass can perfectly fill the mounting groove 120 to form a clamp without damaging the pipe structure, ensuring structural integrity and improving the connection strength between the tension fiberboard 121 and the mounting groove 120. In addition, fiberglass has high impact resistance and compressive strength, and can withstand greater external pressure without being easily damaged, thus improving the bending strength and ring stiffness of the pipe.

[0024] In this embodiment, two sets of tension fiber structures 12 are provided on the pipe wall profile 1. The two sets of tension fiber structures 12 are spaced apart, with the spacing being 1 / 5 of the length of the pipe wall profile 1. This allows the tension fiber structures 12 to be wound more evenly on the pipe body, increasing the compressive strength area. In addition, when the tension fiber plate 121 is installed in the mounting groove 120, the top surface of the tension fiber plate 121 is flush with the outer surface of the pipe wall profile 1, making the pipe body surface flat and smooth, and with strong integrity.

[0025] In this embodiment, in order to improve the connection stability between the tensioned fiberboard 121 and the mounting groove 120, a limiting groove 122 is also provided in the mounting groove 120 to prevent the tensioned fiberboard 121 from falling out of the mounting groove 120. There are two sets of limiting grooves 122, which are located on the left and right sides of the bottom of the mounting groove 120 and extend downward. The width of the limiting groove 122 gradually decreases from bottom to top, thus forming a constriction portion 123 at the groove opening. The tensioned fiberboard 121 has downward protruding limiting portions 125 on both sides. The limiting portions 125 extend into the limiting groove 122 to form a limit, thereby improving the connection strength and preventing the tensioned fiberboard 121 from falling out of the mounting groove 120.

[0026] Furthermore, to further improve the strength of the tube body, a reinforcing groove 124 is provided in the mounting groove 120 between the two sets of limiting grooves 122. A reinforcing part 126 protrudes downward from the middle of the tensioning fiberboard 121. The reinforcing part 126 extends into the reinforcing groove 124 to form a pressure. When the tube body is subjected to bending stress, the stress on the tube wall profile 1 will act on the two sides of the groove wall of the reinforcing groove 124, and then press against the two sides of the reinforcing part 126 to form support. When the tube body is subjected to compressive stress, the spirally wound reinforcing part 126, which forms a spiral ring, can further improve the ring stiffness of the tube body, thereby improving the compressive strength.

[0027] Furthermore, by providing a reinforcing groove 124 and two sets of limiting grooves 122 in the mounting groove 120, the reinforcing groove 124 and the limiting grooves 122 on both sides form buckles 127 for laterally tightening the fiberboard 121. The limiting portions 125 on both sides of the tightening fiberboard 121 form a lateral tightening effect through the two buckles 127. When the tube body is subjected to bending stress causing the mounting groove 120 to expand to both sides, the limiting portions 125 on both sides of the tightening fiberboard 121 are tightened to the outside of the two buckles 127, thereby preventing the mounting groove 120 from expanding further. Conversely, when the bending stress causes the mounting groove 120 to contract inward, the groove walls on both sides of the mounting groove 120 press against the sides of the tightening fiberboard 121, thereby preventing the mounting groove 120 from contracting further, thus achieving the effect of bending resistance.

[0028] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
