DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application: Specific embodiment 1:

[0041] like Figure 1 As shown, the building unit includes a first building block 1 and a second building block 3 arranged in sequence in the transverse direction, and two rotation grooves 2 are symmetrically arranged on both sides of the first building block 1 in the transverse direction. Figure 2 As shown, the first building block 1 includes a first building plate 19, a second building plate 20 and an intermediate plate 21, wherein the first building plate 19 and the second building plate 20 are arranged in parallel in the longitudinal direction, and the intermediate plate 21 is arranged between the first building plate 19 and the second building plate 20 and is located in the middle of the first building plate 19 and the second building plate 20 in the transverse direction. The first building plate 19 and the second building plate 20 are connected and fixed together through the intermediate plate 21, so that the first building block 1 is in an "I" shape as a whole, and two rotation grooves 2 are formed at the transverse ends of the first component plate.

[0042] like Figure 1 , 2As shown, both lateral sides of the second building block 3 are provided with hinged ends adapted to the rotation groove 2. The hinged ends are inserted and hinged in the rotation groove 2, and the hinge axis thereof extends in the longitudinal direction. Specifically, a threaded hole 4 extending in the radial direction is provided at the position of the first building block 1 corresponding to the rotation groove 2, and a movable hole 6 is provided at the position of the hinged end of the second building block 3 corresponding to the threaded hole 4. The threaded hole 4 and the movable hole 6 are penetrated together by a limit screw 5 extending in the longitudinal direction, so that the second building block 3 can rotate around the limit screw 5. In actual use, when the ground has a certain inclination, the bottom surface of the second building block 3 can be made to fit with the ground by rotating the second building block 3, so as to avoid a gap between the building unit and the ground, which may cause water leakage.

[0043] In this embodiment, preferably, the first building block 1 and the second building block 3 have the same height, so when the ground is flat, the bottom surfaces of the first building block 1 and the second building block 3 are coplanar, which can ensure the overall flood control height of the construction channel on the one hand, and facilitate processing and assembly on the other hand. The hinged end of the second building block 3 is sealed with the rotating groove 2, which can ensure that when diverting water, the two are tightly fitted, the water will not flow out from the gap between the two, will not affect the surrounding buildings, and ensure the water diversion effect.

[0044] In this embodiment, the component unit further includes a fixing structure, which is used to fix the first building block 1 and the second building block 3 on the ground. The fixing structure includes a first fixing block 7, a second fixing block 9 and a positioning nail 8, the first fixing block 7 and the second fixing block 9 are respectively fixed on the side of the first building block 1 and the second building block 3, and the first fixing block 7 and the second fixing block 9 are both fixed on the ground by the positioning nail 8.

[0045] Specifically, the first fixing block 7 and the second fixing block 9 are arranged on the same side in the longitudinal direction, and the first fixing block 7 and the second fixing block 9 are both provided with positioning holes (not shown in the figure) adapted to the positioning nails 8, and the positioning nails 8 pass through the positioning holes and are nailed into the ground, thereby fixing the first building block 1 and the second building block 3 on the ground. Of course, in other embodiments, the first fixing block 7 and the second fixing block 9 can be arranged on both sides in the longitudinal direction.

[0046] Preferably, in this embodiment, a limit block 10 is provided at the upper end of the positioning nail 8. When the positioning nail 8 is nailed into the ground, the limit block 10 and the upper side surfaces of the first fixed block 7 and the second fixed block 9 stop and limit the first building block 1 and the second building block 3 to prevent the movement of the first building block 1 and the second building block 3, thereby preventing the first building block 1 or the second building block 3 from detaching from the positioning nail 8 when impacted.

[0047] In this embodiment, preferably, two first fixing blocks 7 are arranged on the first building block 1 at intervals in the lateral direction. This can improve the impact resistance of the building unit and improve the fixing stability. One second fixing block 9 is arranged on the second building block 3 because, when the building channel is actually assembled, the hinged ends on both sides of the second building block 3 will penetrate into the rotation groove 2 of the opposite ends of the adjacent first building block 1, and the second building block 3 can ensure the fixing reliability by using the first building block 1. Of course, in other embodiments, when meeting the actual use requirements, the number of first fixing blocks 7 can be set according to the actual use requirements, such as setting three or four at intervals, or even only one.

[0048] In this embodiment, preferably, Figure 3 , 4 As shown, the fixing structure also includes a third fixing block 11 fixedly arranged on the side of the first building block 1, and a ground-breaking sharp corner is arranged at the lower end of the third fixing block 11. Specifically, the third fixing block 11 is arranged as a whole between the two first fixing blocks 7, and the third fixing block 11 is arranged on the same side as the first fixing block 7. The third fixing block 11 can improve the stability of the building unit, and the ground-breaking sharp corner is arranged at the lower end of the third fixing block 11, so that the third fixing block 11 can break the soil and go deep into the ground.

[0049] The third fixed block 11 includes a placement block 12 fixedly arranged on the side of the first building block 1, the bottom surface of the placement block 12 is coplanar with the bottom surface of the first building block 1, and a support plate 13 is fixedly arranged on the side of the placement block 12 facing away from the first building block 1, and the lower part of the support plate 13 extends out of the bottom surface of the first building block 1. In this way, in actual use, it can be ensured that the support plate 13 is effectively penetrated into the ground, and the reliability of fixation is ensured. A ground-breaking block 14 is arranged at the lower end of the support plate 13. The ground-breaking block 14 is a structure with a larger upper part and a smaller lower part, and the width of which gradually decreases from top to bottom. The lower end of the ground-breaking block 14 constitutes the above-mentioned ground-breaking sharp angle. The third fixed block 11 is designed in blocks, and the placement block 12 can be used to locate the position of the support plate 13, so that the support plate 13 will not shift when placed.

[0050] Preferably, a positioning groove 17 adapted to the placement block 12 is provided on one side of the support plate 13 facing the placement block 12, the positioning groove 17 extends vertically and the upper end of the positioning groove 17 extends to the upper side of the support plate 13. The placement block 12 is vertically slidably arranged on the positioning groove 17, and the support plate 13 is fixedly connected to the placement block 12 by fixing screws 18. The positioning groove 17 facilitates the positioning of the support plate 13 to avoid deviation when the support plate 13 is driven into the ground.

[0051] Preferably, in this embodiment, anti-loosening blocks 15 are provided on both lateral sides of the support plate 13. The anti-loosening blocks 15 are vertically positioned below the first building block 1 as a whole. A soil-breaking piece 16 is fixedly provided at the lower end of the anti-loosening block 15. The soil-breaking piece 16 is also a structure with a larger upper part and a smaller lower part, and the width of the soil-breaking piece 16 gradually decreases from the top to the bottom. In this way, the soil-breaking piece 16 is convenient for breaking the soil and for the anti-loosening block 15 to enter the ground. When the first building block 1 is repeatedly impacted and tends to move upward, the anti-loosening block 15 can be used to prevent the support plate 13 from moving upward, thereby improving the stability of the construction channel and reducing the probability of the construction channel tilting when impacted by floods.

[0052] Working process of this application:

[0053] First, place the first building block 1 on the ground that needs drainage, pass the positioning nail 8 through the corresponding first fixed block 7, and use a hammer to drive the positioning nail 8 into the ground until the limit block 10 stops at the upper end of the first fixed block 7. Then place the support plate 13 near the placement block 12, so that the placement block 12 fits with the positioning groove 17 of the support plate 13. At this time, the lower end of the soil-breaking block 14 contacts the ground, and the soil-breaking block 14 is hammered into the ground by a hammer. At the same time, the soil-breaking piece 16 breaks the soil and drives the anti-loosening block 15 deep into the ground. When the support plate 13 is nailed into a certain depth, the support plate 13 is fixed together with the placement block 12 by the fixing screw 18, and the soil is filled in the movable path of the anti-loosening block 15 and compacted with a hammer, so as to fix the first building block 1 on the ground and complete the limit of the first building block 1.

[0054] Then, the hinged end of the second building block 3 is inserted into the rotation groove 2 of the first building block 1, and the limiting screw 5 is passed through the threaded hole 4 and the movable hole 6, so that the second building block 3 is limited and can only rotate around the limiting screw 5. When the ground has a certain inclination, the second building block 3 is rotated up and down. When the bottom end of the second building block 3 is in contact with the ground, the positioning nail 8 is passed through the second fixing block 9, and the positioning nail 8 is hammered into the ground to limit the second building block 3 and complete the fixing of the second building block 3.

[0055] Then place another first building block 1 on the other side of the second building block 3 in the horizontal direction, so that the hinged end of the second building block 3 on this side is hingedly connected to the rotating groove 2 on the opposite side of the other first building block 1, and at the same time adjust the position of the first building block 1 so that it fits the ground, repeat the above steps, and fix the first building block 1 on the ground. In this way, the first building block 1 and the second building block 3 are installed alternately in sequence, so that a construction channel can be formed to divert water to a designated location, and the construction channel is easy to adapt to uneven ground and is not easy to leak, thereby improving the application range of the device.

[0056] In summary, the construction channel of the utility model is constructed by symmetrically setting the rotating groove 2 on the two lateral sides of the first building block 1, and the hinged end of the second building block 3 is hingedly connected in the rotating groove 2. In actual use, when the ground has a certain inclination, the second building block 3 can be rotated to make the bottom surface of the second building block 3 fit with the ground, so as to avoid the formation of gaps between the construction unit and the ground to cause water leakage. The construction channel is formed by alternately installing the first building block 1 and the second building block 3, so that the bottom surface of the entire construction channel can be adapted to the terrain direction, so that the bottom surface of the construction channel can be fitted on the uneven ground, which is convenient for drainage on the one hand, and can avoid water leakage from the contact point between the construction channel and the ground on the other hand, so as to ensure the flood control effect. The construction unit can be firmly fixed on the ground by using the fixed structure, which can resist the impact of water flow and ensure continuous and effective drainage.
