[0002] Ditch is a general term for waterways dug for irrigation or drainage. When laying ditches, it is necessary to dig trenches first, and then cast concrete ditches on site or place prefabricated concrete ditch blocks in the ditch. Casting concrete ditches on site is more complicated due to the complex on-site environment. Concrete ditches are easily damaged by external forces when solidifying. Therefore, pre-cast concrete ditch blocks are now mostly used in controllable sites. The ditches are then spliced ​​by placing prefabricated concrete ditch blocks. When prefabricated concrete ditch blocks are used, the joints of the ditch blocks are prone to deviations during placement, which can cause water leakage at the joints of the ditch blocks.

When two ditch blocks abut against each other, the elastic sheet improves the sealing between the ditch blocks by deformation. The wavy elastic sheet can make the gap between the two ditch blocks wavy when spliced, thereby extending the length of the gap between the two ditch blocks and reducing the probability of water leakage in the gap; 3. The separation net divides the ditch into two layers. The lower layer is used to plant aquatic plants and put some small aquatic organisms to form an ecosystem in the ditch. The upper layer is used for irrigation or drainage. The lower ecosystem reduces the probability of the ditch becoming smelly due to long-term use. Baffles are set at the mesh of the separation net. The baffles are inclined in the direction of water flow to block the water flow and reduce the probability of water flowing too fast and directly rushing into the ecosystem below, causing the ecosystem to be destroyed; 4. Existing ditch construction usually adopts the method of digging the ditch first and then placing the ditch board. However, some ditches are long and the digging period is long. When the whole ditch is dug, it is easy to collapse in some areas of the ditch, which affects the placement of the ditch blocks and needs to be cleaned again. By placing the ditch blocks after digging the ditch, the probability of the local soil of the ditch falling into the ditch due to the ditch digging for too long can be reduced, making the ditch construction more convenient. At the same time, if rainy and snowy weather occurs during the construction process, the construction can be stopped at any time, and the ditch under construction will not be affected by rainy and snowy weather after the suspension of work; 5. Through the cooperation of the shovel plate and the guide plate, the soil is guided to both sides of the tunnel through the guide plate during the process of lifting the soil, which facilitates the excavation of the tunnel; 6. The receiving platform is driven to slide by the gravity of the ditch block, and then the lifting platform is driven to rise by the driving rope to shovel up the soil. The ditch can be dug while the ditch block is placed, which saves time and makes ditch digging more labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, in this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", and "connected" appear, they should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection, a limited connection such as an interference fit, a transition fit, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium; therefore, for ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0024] The present application embodiment discloses an ecological water conservancy ditch, referring to Figure 1 and Figure 2 , including a ditch 1 dug on the ground by excavation equipment, a plurality of prefabricated ditch blocks 2 are placed in the ditch 1, and the plurality of ditch blocks 2 are connected end to end to form a water conservancy ditch, and positioning rods 3 are arranged on both sides of one end of the ditch block 2 in the length direction. When the ditch block 2 is placed in the ditch 1, the positioning rod 3 is inserted into the soil on both sides of the ditch 1, and one end of the positioning rod 3 inserted into the soil is chamfered to facilitate the insertion of the positioning rod 3, and a positioning plug hole 4 is opened on the positioning rod 3. Positioning plug rods 5 are arranged on both sides of the other end of the ditch block 2 in the length direction. When two ditch blocks 2 are connected at the ends, the positioning plug rod 5 of one ditch block 2 is inserted into the other ditch block 2, so that the connection parts of the two ditch blocks 2 are abutted and aligned with each other, and the end of the positioning rod 5 inserted into the positioning hole 4 is chamfered to facilitate the insertion of the positioning rod 3, and a limit block is fixedly arranged at the end of the positioning rod 5 away from the insertion positioning hole 4, and the limit block can align the two ditch blocks 2 in the height direction. The positioning rods 5 located on both sides of the ditch block 2 cooperate with the positioning hole 4 to achieve the positioning of the two ditch blocks 2 when spliced, reduce the probability of misalignment when splicing the ditch blocks 2, and thus reduce the probability of water leakage at the splicing of the ditch blocks 2; the insertion of the positioning rod 3 itself also has a reinforcement effect on the placement of the ditch block 2 in the excavated ditch 1.

[0025] Reference Figure 1 and Figure 2Elastic sheets 6 are fixed at both ends of the ditch block 2 in the length direction. The elastic sheets 6 are wavy along the width direction of the ditch block 2. In this embodiment, a metal sheet is selected for elasticity. The metal sheet is fixed by directly casting the metal sheet in the ditch block 2. When the two ditch blocks 2 abut against each other, the elastic sheet 6 improves the sealing between the ditch blocks 2 through deformation. The wavy elastic sheet 6 can make the gap between the two ditch blocks 2 wavy when spliced, thereby extending the length of the gap between the two ditch blocks 2 and reducing the probability of water leakage in the gap.

[0026] Reference Figure 1 and Figure 2 A separation net 7 is installed in the ditch block 2. The separation net 7 divides the ditch into two layers. The lower layer is used to plant aquatic plants and put some small aquatic organisms to form an ecosystem in the ditch. The upper layer is used for irrigation or drainage. The probability of the ditch stinking due to long-term use is reduced through the ecosystem in the lower layer. A baffle is set at the mesh of the separation net 7. The baffle is inclined toward the direction of water flow to block the water flow, thereby reducing the probability of the water flow rushing directly into the ecosystem below too quickly, causing the ecosystem to be destroyed.

The existing ditch construction usually adopts the method of digging a ditch first and then The method of placing and laying the ditch board after the ditch 1 is completed is adopted. However, some ditches are long and the digging period is long. After the whole ditch 1 is dug, it is easy to collapse in some areas of the ditch 1, thereby affecting the placement of the ditch block 2, and the ditch 1 needs to be cleaned again. By placing the ditch block 2 after digging the ditch 1, the probability of the local soil of the ditch 1 falling into the ditch 1 due to the ditch 1 being dug for too long can be reduced, making the ditch construction more convenient.

When the lifting platform 9 slides to near the top of the body 8, the guide plate 11 is inclined toward the side away from the shovel plate 10. The upper surface of the shovel plate 10 is an inclined surface, and the upper surface of the shovel plate 10 is inclined toward the two guide plates 11. The body 8 is placed in the excavated tunnel, and then the shovel plate 10 and the guide plate 11 are inserted into the soil, and the lifting platform 9 is slid and lifted to shovel the soil on one side of the tunnel. In the process of lifting the soil, the soil is guided to both sides of the tunnel through the guide plates 11, which facilitates the excavation of the tunnel.
