[0002] Land remediation refers to the process of applying engineering and biological measures to improve undesirable land properties, increase land utilization and productivity, and facilitate intensive management. This remediation process often involves removing harmful components from the upper soil layers through hydraulic infiltration.

[0003] At present, the commonly used methods of hydraulic infiltration are open ditch drainage on the ground and buried drainage pipe drainage. Open ditch drainage on the ground requires the use of large-scale mechanical equipment, which is expensive, has a long cycle, and occupies effective land use area; buried drainage pipe drainage requires laying a large number of drainage pipes, which is difficult to construct, and the permeable pores are easily clogged. Drainage pipes also have a certain service life and are prone to forming new pollution sources after aging. Therefore, how to design a device that can form a natural groove hole underground, and thus better solve the problem of allowing harmful components to flow out smoothly during soil remediation, is a technical problem that has troubled technical personnel in this field.

The traction rod 1 is usually connected to a traction power, which is not limited here. The forward direction of the traction rod 1 is the front direction. Figure 1 The direction of the middle arrow indicates the forward travel direction of the traction rod 1. A vertically arranged front cutting plate 2 is fixedly installed on one side of the traction rod 1, and a vertically arranged rear cutting plate 4 is fixedly installed on the other side of the traction rod 1. The front cutting plate 2 and the rear cutting plate 4 are arranged opposite to each other and the rear cutting plate 4 is located downstream of the front cutting plate 2. A horizontally extending flat cutting plate 3 is provided at the bottom of the front cutting plate 2, and a lifting plate 5 is provided at the bottom of the rear cutting plate 4. The lifting plate 5 corresponds to the position of the flat cutting plate 3. The lifting plate 5 and the flat cutting plate 3 are both located directly below the traction rod 1. The front end of the lifting plate 5 and the rear end of the flat cutting plate 3 are close to each other, and the lifting plate 5 has a lifting surface that gradually rises from front to rear. Figure 2 and Figure 3 , so that when the lifting plate 5 moves forward, a accommodating cavity 11 is formed directly behind the lifting plate 5. The front cutting plate 2, the rear cutting plate 4, the flat cutting plate 3 and the front end surfaces of the lifting plate 5 are all provided with cutting edges. The end of the lifting plate 5 is connected to the groove forming box 6. The groove forming box 6 has a cutting notch 601 facing forward and a soil guide port 602 connected to the rear of the lifting plate 5.

[0025] The operation process of the embodiment of the utility model is as follows:

[0026] like Figure 2 and Figure 3 As shown, after the horizontal cutting plate 3 penetrates the natural soil layer, the traction power drives the traction rod 1 to move horizontally forward, the front cutting plate 2 and the rear cutting plate 4 cut the soil on the left and right sides, the horizontal cutting plate 3 cuts the soil at the bottom, and the lifting plate 5 lifts the cut soil, so that a receiving cavity 11 is formed directly behind the lifting plate 5. At the same time, the groove forming box 6 cuts the soil on the other side of the rear cutting plate 4, cutting a groove in the natural soil passed by the cutting notch 601, and guiding this natural soil into the receiving cavity 11 through the soil guide plate 603, thus forming an underground groove hole 12 on one side of the receiving cavity 11. The underground groove hole 12 formed by the utility model has natural soil above the groove part, which is undisturbed and has a certain structural strength. At the same time, the position of the receiving cavity 11 is filled and compacted with soil, which provides strong support for the groove and ensures the integrity and strength of the groove hole 12 structure. It has the advantages of simple operation, high efficiency and low cost.
