[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] The utility model provides a drainage channel for saline-alkali land treatment, including a drainage channel body 1 and a shielding cover, wherein a fixing plate 2 is evenly fixedly connected to the top of the drainage channel body 1, and a clamping hole 11 is provided at one end of the fixing plate 2 away from the drainage channel body 1, and clamping rods 4 are fixedly connected to both sides of the bottom of the shielding cover, and the clamping rods 4 are adapted to the clamping holes 11, and when the clamping rods 4 are clamped with the clamping holes 11, the end of the fixing plate 2 away from the drainage channel body 1 contacts the inner wall of the shielding cover, and the fixing plate 2 supports the shielding cover. It can be seen from the above description that the shielding cover and the drainage channel body 1 can be quickly fixed or separated.
[0020] There is a drainage gap between the bottom of the shielding cover and the top of the drainage channel body 1. The saline-alkali land water can be discharged into the drainage channel body 1 through the drainage gap. The drainage gap can be set according to needs and is not limited here. The shielding cover is an arc-shaped structure protruding outward. The end of the fixed plate 2 away from the drainage channel body 1 is arc-shaped. The outer diameter of the end of the fixed plate 2 away from the drainage channel body 1 is the same as the inner diameter of the shielding cover. The length of the shielding cover is less than the length of the top of the drainage channel body 1, and the end of the shielding cover is provided with a rounded corner. With this arrangement, the shielding cover can shield the drainage channel body 1, reduce the evaporation of the drainage channel body 1, and reduce the water loss in the drainage channel. The evaporated water and rainwater can slide along the shielding cover into the drainage channel body 1, and the shielding cover can block fallen leaves, dust, etc., reduce the amount of fallen leaves entering the drainage channel, and extend the cleaning frequency of the drainage channel. The length of the shielding cover can be set according to needs and is not limited here.
[0021] The outer surface of the shielding cover is provided with a heat-insulating coating, which may be a nano heat-insulating coating. The inner wall of the shielding cover is provided with an anti-stick coating, which may be a special anti-fouling and anti-stick coating. The setting of the heat-insulating coating can reduce the influence of external heat on drainage in the drainage channel and reduce the evaporation of water. The setting of the anti-stick coating can facilitate water droplets adhering to the inner wall of the shielding cover to slide back into the drainage channel.
[0022] The above-mentioned shielding cover includes a fixed cover 5 and a movable cover 3, and the bottoms of the fixed cover 5 and the movable cover 3 are fixedly connected with a clamping rod 4, and the fixed cover 5 and the movable cover 3 are alternately arranged. Through the arrangement of the movable cover 3 and the fixed cover 5, when the drainage channel is in use, the staff can clean the silt in the drainage channel by disassembling the movable cover 3, and when the drainage channel is in use, the staff can replace the damaged fixed cover 5 or movable cover 3 separately, which is convenient for repairing the shielding cover.
[0023] The above-mentioned drainage channel body 1 includes an outer anti-seepage plate 9, an inner isolation plate 6 and a connecting plate 10. The outer anti-seepage plate 9, the inner isolation plate 6 and the connecting plate 10 form a sealed cavity. Through the setting of the outer anti-seepage plate 9, the flow of salt can be blocked to avoid the transfer of salt in the drainage channel. The inner isolation plate 6 and the connecting plate 10 can be opposite. A shaping layer 7 is provided in the middle of the inner cavity of the sealed cavity. The outer surface of the shaping layer 7 is wrapped with a buffer layer 8. The buffer layer 8 is fixedly connected to the inner wall of the sealed cavity. Through the setting of the buffer layer 8, the shaping layer 7, the outer anti-seepage plate 9, the inner isolation plate 6 and the connecting plate 10 have deformation space, which reduces the probability of deformation of the drainage channel due to thermal expansion and contraction, and the buffer layer 8 can protect the shaping layer 7, reduce the influence of the external temperature on the shaping layer 7, and extend the service life of the drainage channel. In some embodiments of the present application, the outer anti-seepage plate 9, the inner isolation plate 6 and the connecting plate 10 are all made of fiberglass, the outer surface of the fiberglass is coated with an anti-seepage membrane, the shaping layer 7 is made of concrete, and the buffer layer 8 is made of rubber.
[0024] To sum up: when the drainage channel for saline-alkali land treatment is in use, it is semi-open, and the shielding cover can shield the drainage channel to reduce the evaporation of water in the drainage channel, and some of the evaporated water will condense when it comes into contact with the shielding cover, gather into water droplets and drip back into the drainage channel, further reducing the loss of water in the drainage channel. The drainage channel frame composed of the outer anti-seepage plate 9, the inner isolation plate and the connecting plate has an anti-seepage function, which avoids the transfer of salt in the drainage channel and reduces the impact of the drainage channel on the surrounding soil; the buffer layer provides deformation space for the drainage channel frame and the shaping layer 7, reducing the probability of deformation of the drainage channel due to thermal expansion and contraction, and the buffer layer 8 can protect the shaping layer 7, reduce the impact of the external temperature on the shaping layer 7, and extend the service life of the drainage channel.
