Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, specifically a novel water nail pipe. Background Technology

[0002] Water nail capillary drainage pipe, or simply water nail pipe, is a new type of drainage technology that combines capillary action and siphon principle. It is widely used in water conservancy projects, roadbed drainage, tunnel seepage prevention, railway slope drainage and other fields. Water nail drainage pipe is a water nail made of PVC pipe or PE pipe wrapped with a capillary permeable drainage strip. Combined with T-junctions and T-junctions connecting the water nails and the water collection pipe, as well as water nail joints connecting two water nails, a complete drainage system is formed.

[0003] The core component of the water nail capillary drainage pipe is the capillary permeable drainage belt, whose surface is designed with dense Ω-shaped water guiding grooves (approximately 1mm in diameter and spaced 1.5mm apart). When the soil contains water, the water is adsorbed into the drainage pipe through capillary action. Subsequently, a negative pressure is formed under the siphon effect, accelerating drainage. At the same time, due to the groove structure being larger inside and smaller outside (groove width approximately 0.3mm), water is drawn into the pipe by surface tension. Meanwhile, soil particles settle due to gravity, achieving automatic separation of water and soil and avoiding clogging. Once a continuous water flow is formed in the pipe, the siphon effect makes the drainage efficiency far exceed that of traditional gravity drainage.

[0004] When installing capillary water nail pipes, it is necessary to precisely align the Ω-shaped water guide grooves on the capillary drainage strip. This is difficult to do manually and affects the installation efficiency. Therefore, a new type of water nail pipe is provided. Utility Model Content

The connecting slot is used to connect the water guide slots on the two water nail capillary drainage pipes.

[0010] As a further embodiment of this utility model: a centering ring block is fixed in the middle of the inner side of the mating sleeve, the inner diameter of the centering ring block matches the inner diameter of the central tube, and the distance from the end face of the centering ring block to the end face of the mating sleeve matches the length of the end face of the central tube protruding from the limiting groove.

[0012] As a further embodiment of this utility model: the central tube and the limiting groove are integrally formed by extrusion molding, and the annular capillary drainage strip, the water guide hole, and the limiting strip are integrally formed by extrusion molding.

[0013] The mating sleeve, mating strip, connecting groove, and centering ring block are integrally formed by injection molding.

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.

[0021] Please see Figures 1-3 In this embodiment of the utility model, a novel water nail pipe includes a water nail capillary drainage pipe 1 composed of a central pipe 101 and an annular capillary drainage strip 103. The annular capillary drainage strip 103 is wrapped around the outside of the central pipe 101. The outer side of the annular capillary drainage strip 103 is formed with a plurality of annularly distributed water guiding grooves 104. The outer side of the central pipe 101 is integrally formed with a plurality of annularly distributed limiting grooves 102. The inner side of the annular capillary drainage strip 103 is formed with a limiting strip 105 that engages with the limiting grooves 102. The mutual engagement between the limiting strip 105 and the limiting grooves 102 is used to limit the circumferential direction of the annular capillary drainage strip 103 and the central pipe 101.

[0022] Two water nail capillary drain pipes 1 are assembled by connecting components 2. The connecting components 2 include connecting outer pipe 201, connecting rubber sleeve 202, connecting clip 203, and connecting slot 204.

[0023] The docking sleeve 202 is fixed to the middle of the inner side of the docking outer tube 201. Multiple docking clips 203 are provided, and their number and position correspond one-to-one with the number and position of the limiting groove 102. The docking clips 203 are formed on the outside of the docking sleeve 202. The number and position of the docking clips 203 correspond one-to-one with the number and position of the water guide groove hole 104.

[0024] The end of the central tube 101 protrudes to the end of the annular capillary drainage strip 103. The end of the central tube 101 is inserted into the inner side of the docking sleeve 202. The docking clip 203 is engaged with the limiting groove 102 to achieve automatic alignment of the connecting slot 204 and the water guide slot 104. The connecting slot 204 is used to connect the water guide slots 104 on the two water nail capillary drainage tubes 1.

[0025] In this embodiment, the operation of connecting the water nail capillary drain pipe 1 is as follows:

[0026] First, apply glue to the outer side of the part of the central tube 101 that protrudes from the annular capillary drainage strip 103. At the same time, apply glue to the inside of the mating sleeve 202. Then, insert the end of the central tube 101 into the inside of the mating sleeve 202, and the mating clip 203 is engaged with the inside of the limiting groove 102. This can achieve automatic alignment between the connecting groove hole 204 and the water guiding groove hole 104.

[0027] Next, insert the center tube 101 on the other water nail capillary drain tube 1 into the inner side of the other end of the docking sleeve 202. This completes the assembly and docking of the two water nail capillary drain tubes 1. The water guide slots 104 on the two water nail capillary drain tubes are connected through the connecting slot 204. The overall operation is simple and convenient.

[0028] Please refer to this carefully. Figures 1-3 A centering ring block 205 is fixed in the middle of the inner side of the mating sleeve 202.

The distance from the end face of the centering ring block 205 to the end face of the mating sleeve 202 matches the length of the central tube 101 protruding from the end face of the limiting groove 102.

[0029] The inner diameter of the connecting outer tube 201 matches the outer diameter of the annular capillary drainage belt 103. The length of the connecting outer tube 201 is greater than the length of the connecting rubber sleeve 202. The two ends of the connecting rubber sleeve 202 protrude to the two ends of the connecting rubber sleeve 202.

[0030] In this embodiment: the ends of the two water nail capillary drainage pipes 1 can be positioned by the central ring block 205. When the end of the central pipe 101 is in contact with the end face of the central ring block 205, the annular capillary drainage strip 103 is in contact with the end face of the connecting sleeve 202, thereby realizing the connection and conduction between the connecting slot 204 and the water guiding slot 104.

[0031] Please refer to this carefully. Figures 1-3 The central tube 101 and the limiting groove 102 are integrally formed by extrusion molding, and the annular capillary drainage strip 103, the water guide hole 104, and the limiting strip 105 are integrally formed by extrusion molding.
