Description

Technical Field

[0001] The utility model relates to the technical field of drainage blind ditches, in particular to a special pipe for highway drainage blind ditches. Background Art

[0002] In southern my country, where rainfall is relatively abundant, many roads have adopted measures to add drainage blind ditches to improve drainage conditions. However, in actual applications, these drainage blind ditches often accumulate mud for a long time and lack an effective cleaning mechanism, which eventually leads to blockage.

[0003] Chinese patent CN202214684 U proposes a special pipe for drainage blind ditches. Drain holes are provided on both the inner and outer drainage pipe walls. Some rainwater does not flow smoothly along the pipe as expected, but instead seeps into the area below the blind ditch through these holes. This phenomenon not only reduces the overall drainage capacity of the pipe, but may also adversely affect the soil structure below the blind ditch, such as soil erosion and water oversaturation. Therefore, from a professional perspective, this design may have limitations in practical applications and requires further optimization to overcome its inherent defects. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and then proposes a special pipe for highway drainage blind ditch.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A special pipe for highway drainage blind ditch includes an outer pipe with a plurality of water inlet holes. A plurality of curved mesh hard and tough semi-permeable pipes are slidably fitted inside the outer pipe. Adjacent curved mesh hard and tough semi-permeable pipes are connected together by guide arc plates.

[0007] Furthermore, one-third of the flat impermeable portion of the curved mesh-shaped hard and tough semi-permeable tube is at the bottom.

[0008] Furthermore, guide grooves are formed on both sides of the inner wall of the outer tube, and guide arc plates are slidably fitted in the guide grooves.

[0009] Furthermore, the guide arc plate is fixedly connected to the curved mesh-shaped hard and tough semi-permeable tube by screws.

[0010] Furthermore, a fixing component is fixedly connected to the bottom of the outer tube.

[0011] Furthermore, the fixing assembly includes a fixing plate, which is fixedly connected to the bottom of the outer tube by bolts, and a plurality of ground nails are provided at the bottom of the fixing plate.

[0012] Compared with the existing technology, the beneficial effects of the present invention are: the present invention can achieve the dual advantages of efficient drainage and easy cleaning. The water inlet hole on the outer tube ensures that rainwater can enter smoothly, while the internal curved mesh hard and tough semi-permeable tube effectively filters and guides the water flow. At the same time, its sliding design facilitates regular cleaning, avoiding the problem of easy clogging of traditional drainage blind ditches. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0018] like Figure 1-Figure 2 As shown, a special pipe for highway drainage blind ditch includes an outer pipe 100, which is provided with a plurality of water inlet holes 101. A plurality of curved mesh hard and tough semi-permeable pipes 200 are slidably fitted inside the outer pipe, and adjacent curved mesh hard and tough semi-permeable pipes are connected together by a guide arc plate 3.

[0019] Furthermore, the impermeable portion of one-third of the curved mesh-shaped semipermeable tube is located at the bottom. This type of tube can be purchased externally. It is made primarily of high-density polyethylene plastic, with a certain proportion of antioxidants and acid- and alkali-resistant agents added. The tube is extruded through a hot extruder at high temperature, oscillating uniformly in a circular motion to form a mesh tube with uniformly dense pores. The tube is water-permeable on two-thirds of its surface and impermeable on one-third of its surface.

[0020] Furthermore, guide grooves 102 are formed on both sides of the inner wall of the outer tube, and guide arc plates 3 are slidably fitted in the guide grooves.

[0021] Furthermore, the guide arc plate is fixedly connected to the curved mesh-shaped hard and tough semi-permeable tube by screws 31.

[0022] In at least one embodiment, Figure 3 As shown, the bottom of the outer tube is also fixedly connected to a fixing assembly, which includes a fixing plate 300. The fixing plate is fixedly connected to the bottom of the outer tube by bolts 301, and a plurality of ground nails 302 are provided at the bottom of the fixing plate.

[0023] Working method: Use guide arc plates to connect adjacent curved mesh hard and tough semipermeable tubes to ensure that the connection between them is stable and can maintain a certain degree of sliding. The guide arc plates can be fixedly connected to the curved mesh hard and tough semipermeable tubes by screws. Place the curved mesh hard and tough semipermeable tubes into the outer tube, check the guide grooves on both sides of the inner wall of the outer tube, and ensure that they can fit tightly with the guide arc plates to guide the sliding of the curved mesh hard and tough semipermeable tubes in the outer tube. When water on the road enters the outer tube through the water inlet hole 101, the water will flow into the curved mesh hard and tough semipermeable tube through the permeable part of the curved mesh hard and tough semipermeable tube and flow away along the curved mesh hard and tough semipermeable tube. Regularly check and clean the curved mesh hard and tough semipermeable tubes to ensure that their water permeability is not affected. If necessary, the curved mesh hard and tough semipermeable tubes can be pulled out from the outer tube to clean the impurities and blockages inside it.

[0024] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
