[0025] The realization of the purpose, functional characteristics and advantages of the present invention will be further described with reference to the embodiments and the drawings. Detailed implementation manners

[0026] The following will describe the embodiments of the present invention in detail with reference to the drawings. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0027] The present invention provides a capillary drainage member and a drainage system, aiming to solve the problem of low water absorption and drainage efficiency of the existing capillary drainage member.

[0028] As Figure 1 And Figure 2As shown, the outer wall of the capillary drainage member 1 is provided with capillary grooves 1.1 arranged along the length direction of the capillary drainage member 1, and both ends of the capillary grooves 1.1 are communicated with the external environment. The capillary grooves 1.1 include a diversion part 1.1.1. The cross-section of the diversion part 1.1.1 is arranged along the radial direction of the capillary drainage member 1. The two ends of the diversion part 1.1.1 in the radial direction of the capillary drainage member 1 are arc-shaped surfaces 1.1.2. The two arc-shaped surfaces 1.1.2 are connected by a plane 1.1.3, and a water inlet 1.1.5 communicated with the external environment is arranged on the arc-shaped surface 1.1.2 at the end far from the central axis of the capillary drainage member 1. In this embodiment, the capillary drainage member 1 is inclined in the soil, and the heights of both ends are different. The water level difference generates a siphon force. The capillary action of the soil continuously attracts water from farther away to the periphery of the drainage member. The water enters the diversion part 1.1.1 under the capillary action of the capillary grooves 1.1. The two ends of the diversion part 1.1.1 of the capillary grooves 1.1 in the radial direction of the capillary drainage member 1 are arc-shaped surfaces 1.1.2. The two arc-shaped surfaces 1.1.2 are connected by a plane 1.1.3, and a water inlet 1.1.5 communicated with the external environment is arranged on the arc-shaped surface 1.1.2 at the end far from the central axis of the capillary drainage member 1, that is, the cross-section of the diversion part 1.1.1 is arranged in a capsule shape. Compared with the circular grooves and water droplet-shaped grooves in the prior art, the capillary action of the capillary grooves 1.1 of the present utility model is enhanced, the equivalent drainage cross-sectional area is increased, the water absorption efficiency is higher, the drainage capacity is stronger, and for the situation of sudden increase in the water content of the soil, the reaction is more sensitive.

[0029] Based on the above embodiment, the capillary grooves 1.1 further include a water absorption part 1.1.6. The capillary grooves (1.1) further include a water absorption part (1.1.6). The water absorption part (1.1.6) is arranged along the radial direction of the capillary drainage member (1), and the water absorption part (1.1.6) is communicated between the water inlet (1.1.5) and the external environment. The capillary action of the water absorption part 1.1.6 can suck the water in the adjacent soil and introduce it into the diversion part 1.1.1, so that the capillary action of the diversion part 1.1.1 can drain the water as soon as possible, further improving the drainage efficiency of the capillary drainage member 1.

[0030] Furthermore, a transition surface 1.1.4 is further arranged between the arc-shaped surface 1.1.2 and the plane 1.1.3. The radian of the transition surface 1.1.4 is 25° to 35°. The transition surface 1.1.4 plays a transitional role between the arc-shaped surface 1.1.2 and the plane 1.1.3 to ensure the smoothness of the inner wall of the diversion part 1.1.1, thereby ensuring the drainage effect of the capillary grooves 1.1 and improving the water absorption efficiency.

[0031] Even further, the radian of the arc-shaped surface 1.1.2 is 110° to 130°. The water sucked into the diversion part 1.1.1 can flow along the arc-shaped surface 1.1.2 to improve the drainage efficiency.

[0032] In one embodiment, if Figure 3 As shown, there are multiple capillary grooves 1.1, which are arranged at intervals along the outer wall of the capillary drainage member 1, and the spacing between two adjacent capillary grooves 1.1 is 0.35mm-0.40mm. As many capillary grooves 1.1 as possible are arranged on the outer wall of the capillary drainage member 1 to improve the water absorption efficiency and drainage capacity of the capillary drainage member 1.

[0033] Specifically, the length of the water absorption part 1.1.6 along the radial direction of the capillary drainage component 1 is 0.7mm-1.0mm, and the width of the water absorption part 1.1.6 is 0.2mm-0.3mm; the length of the flow guide part 1.1.1 along the radial direction of the capillary drainage component 1 is 1.0mm-1.3mm, and the width of the flow guide part 1.1.1 is 0.6mm-1.0mm. Through the above-mentioned size setting, by setting the size of the capillary slot scientifically, the capillary slot can achieve a higher drainage efficiency in use, and can ensure that water can enter the flow guide part 1.1.1 through the water absorption part 1.1.6 under the capillary action, while increasing the cross-sectional area of ​​the flow guide part 1.1.1 as much as possible to ensure the drainage capacity of the capillary drainage component 1.

[0034] In one embodiment, the total area of ​​all water inlets 1.1.5 accounts for 43%-46% of the outer surface area of ​​the capillary drainage component 1; the capillary drainage component 1 is an integrally formed component. The large area of ​​the water inlets 1.1.5 can ensure the drainage capacity and drainage volume, and prevent external mud and sand from entering the interior of the capillary slots; the capillary drainage component 1 is an integrally formed component to ensure the overall structural strength, facilitate production, and reduce installation procedures. Preferably, a hydrophilic agent is evenly applied on the surface of the capillary drainage component 1, so that the drainage component has a more hydrophilic property and a stronger water absorption capacity.

[0035] In one embodiment, if Figure 4 As shown, the capillary drainage component 1 is a drainage pipe, which includes a structural layer and a capillary drainage layer. A drainage channel 1.2 is formed in the structural layer. The capillary drainage layer extends from the outer wall of the structural layer to a direction away from the central axis of the structural layer. The capillary drainage layer is provided with a plurality of capillary grooves 1.1. The capillary grooves 1.1 on the drainage pipe can fully contact with the surrounding soil to ensure drainage efficiency, and there is no need to consider the setting direction when the drainage pipe is set in the soil.

[0036] In one embodiment, if Figure 5As shown in the figure, the capillary drainage member 1 is a drainage board. The drainage board is provided with drainage channels 1.2 arranged at intervals in the width direction, and a plurality of capillary grooves 1.1 are formed on the outer wall of the drainage board. The drainage board is 90 mm long, 30 mm wide, and 3 mm thick. Two stiffening ribs with a width of 1.2 mm are arranged inside to strengthen the strength of the drainage board and evenly divide the inside of the drainage board into three drainage channels 1.2. The plate-shaped drainage member body increases the diversity of the drainage member to cope with different drainage environments. During use, the shape of the capillary drainage member 1 can be changed according to actual needs. When actually used, the long side of the drainage board faces the main water inflow direction, and the short side faces the secondary water inflow direction, so that the drainage efficiency is higher under the premise of using the same material.

[0037] This embodiment also provides a drainage system, as Figure 6 shown. The drainage system includes a plug 2, a joint 3, and a drainage main body. The drainage main body includes a plurality of capillary drainage members 1 as described above. The plurality of capillary drainage members 1 are linearly inclined along the drainage direction, and any two capillary drainage members 1 are connected by a joint; the capillary drainage members 1 at both ends of the drainage main body along the drainage direction are the upper capillary drainage member 1 and the lower capillary drainage member 1 in sequence. The end of the upper capillary drainage member 1 away from the joint is connected to the plug 2, and the end of the lower capillary drainage member 1 away from the joint is connected to the drainage outlet. A plug 2 is arranged at the end of the upper capillary drainage member 1 away from the joint to prevent the drainage efficiency from being reduced due to the blockage of sediment at the end.

[0038] A plurality of capillary drainage members 1 are connected to each other end to end through joints to form an integral body. This integral body is installed inside the soil. The capillary drainage members 1 are arranged obliquely, and the drainage direction is required to be a direction that is horizontally downward. A plug 2 is arranged at the end of the capillary drainage member 1 against the drainage direction to prevent sediment at the end from entering the capillary drainage member 1 and reducing the drainage efficiency. During drainage, the water in the soil body is sucked into the diversion groove through the water absorption seam under the action of capillary force, and then under the combined action of gravity and siphonage, the water is discharged from the soil body through the internal capillary drainage member 1.

[0039] Since the drainage system includes the capillary drainage member 1 as described above, the drainage system has all the beneficial effects of the above-mentioned capillary drainage member 1, which will not be elaborated here one by one.

[0040] When the present utility model is designed, by setting the diversion groove to be capsule-shaped, the capillary action of the capillary groove 1.1 is enhanced. Its equivalent drainage cross-sectional area increases by 18% and 6% respectively compared with the circular cross-section and the water droplet-shaped cross-section, and its water absorption efficiency increases by 6% and 22% respectively compared with the two.

[0041] After the design of the present utility model, a model test of indoor drainage of drain pipes was carried out to compare the drainage performance of the drain pipe with a capsule-shaped flow guide groove with those of the drain pipes with circular and water-drop-shaped flow guide grooves. From the very beginning of the test, the drainage speed of the drain pipe with a capsule-shaped flow guide groove was the fastest. When the test reached 24 hours, the circular, water-drop-shaped and capsule-shaped flow guide groove drain pipes had respectively drained 29.3%, 30.7% and 34.3% of the total water volume in the soil, indicating that the drain pipe with a capsule-shaped flow guide groove could drain more water from the soil sample, that is, it not only had a faster drainage speed but also had a stronger drainage capacity.

[0042] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included in the patent protection scope of the present utility model.
