Abstract
Description
Technical Field
[0001] This utility model relates to the field of soft soil treatment technology, specifically to a plastic drainage board insertion device. Background Technology
[0002] Riverbed fill silt is mostly loose, with high water content, low strength, and high compressibility. It is also mostly shallow silt with extremely low surface bearing capacity. Tracked sluice gate drivers are prone to getting stuck, making it impossible for machinery to enter the site for construction. Traditional manual driving tools (such as steel bars and wooden piles) have weak penetrating power and are difficult to penetrate the surface woven fabric and hard shell layer. When the tool is pulled back after insertion, the drainage board often bounces back or falls off due to soil disturbance or insufficient friction.
[0003] Therefore, it is necessary to propose a plastic drainage board insertion device to solve the above problems. Utility Model Content
[0004] Technical problem to be solved: The purpose of this utility model is to provide a plastic drainage board insertion device to solve the problems mentioned in the background art, such as the easy getting stuck in the tracked insertion machine, the inability of the machine to enter the site for construction, and the weak penetration of traditional manual insertion tools (such as steel bars and wooden piles), which are difficult to penetrate the surface woven fabric and hard shell layer. When the tool is pulled back after insertion, the drainage board often bounces back or falls off due to soil disturbance or insufficient friction.
[0005] Technical solution: To achieve the above objectives, this utility model is implemented through the following technical solution: a plastic drainage board insertion device, including a handle, a connecting plate fixedly installed at one end of the handle, the other end of the connecting plate being wedge-shaped with sharp edges on both sides, and a U-shaped rod fixedly installed on one side of the connecting plate.
[0006] Preferably, the grip includes a connecting rod and a plurality of extension rods, and the connecting rod and the extension rods, as well as the two extension rods, are all threadedly connected.
[0007] Preferably, the connecting plate is a rhomboid steel plate, one of the diagonals of the connecting plate is collinear with the axis of the connecting rod, one end of the connecting rod has a slot along the axial direction, and one corner of the connecting plate is inserted into the slot and welded together with the connecting rod.
[0008] Preferably, the grip further includes a limiting assembly disposed between the connecting rod and the extension rod and between the two extension rods. The limiting assembly includes two limiting rings fixedly fitted along the lower end of the extension rod along the axial direction, and a fixing ring fixedly fitted along the upper end of the connecting rod and the extension rod. A spring and a collar are fitted along the axial direction at intervals on the extension rod between the two limiting rings. Multiple slots are evenly opened along the circumference on the lowest limiting ring of the extension rod and the two fixing rings. Multiple limiting plates are evenly fixedly installed along the circumference on the lower end of the collar. The limiting plates correspond one-to-one with the slots, and one side of the lower end of the limiting plate is a slope.
[0009] Beneficial effects: Compared with the prior art, this utility model provides a plastic drainage board insertion device. This plastic drainage board insertion device has a unique structure and is easy to use. The combination design of the handle allows for flexible adjustment of the extension rod length to adapt to different insertion depth requirements. Moreover, the scale lines on the outer surface can accurately control the insertion depth, meeting the requirements of convenience and accuracy for manual operation. The wedge-shaped cutting edge of the diamond-shaped connecting plate has strong penetrating power, which can efficiently cut through the woven fabric and cut the soil, significantly reducing insertion resistance and improving work efficiency. The enclosed area formed by the U-shaped rod and the connecting plate can temporarily and stably clamp the drainage board. When the device is pulled back, the friction of the soil on the drainage board can be used to achieve reliable placement, ensuring construction quality.
[0010] In addition, in Embodiment 2, the added limiting component, through the mechanical structure of spring preload, inclined guide, and vertical limiting, effectively prevents the threaded connection from loosening during vibration insertion, thereby enhancing the structural stability and long-term reliability of the device.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0014] Example 1: This Example 1 provides a plastic drainage board insertion device, which is a direct improvement on the existing plastic drainage board insertion device. It has a unique structure. Please refer to [link / reference]. Figure 1-5 As shown, the device includes a handle 1. The outer surface of the handle 1 is uniformly marked with scale lines (not shown) along the axial direction for precise control of the insertion depth. A connecting plate 2 is fixedly installed at one end of the handle 1. The other end of the connecting plate 2 is wedge-shaped with sharp edges on both sides. A U-shaped rod 3 is fixedly installed on one side of the connecting plate 2.
[0015] The grip 1 includes a connecting rod 11 and multiple extension rods 12. Both the connecting rod 11 and the extension rods 12 are galvanized steel pipes, and the connecting rod 11 and the extension rods 12, as well as the two extension rods 12, are threaded together. The connecting plate 2 is a rhomboid steel plate. One of the diagonals of the connecting plate 2 is collinear with the axis of the connecting rod 11. One end of the connecting rod 11 has a slot 13 along the axial direction. One corner of the connecting plate 2 is inserted into the slot 13 and welded together with the connecting rod 11.
[0016] Working principle: When using this device, first align the plastic drainage board with the handle 1, then bend the lower end of the plastic drainage board and insert it from bottom to top into the enclosed area between the U-shaped rod 3 and the connecting plate 2. The drainage board is temporarily clamped by the gap between the U-shaped rod 3 and the connecting plate 2. No additional fixing parts are required, making operation convenient. At this time, the worker holds the handle 1 and quickly inserts the connecting plate 2 along with the drainage board into the soil until the designed depth. The wedge-shaped end of the lower end of the connecting plate 2 has two sharp edges that can quickly cut the woven fabric and the soil. The insertion depth can be determined by the marked scale lines on the handle 1. After the drainage board is brought to the designated depth, the handle 1 is pulled out of the soil. The drainage board remains in the soil due to the friction of the surrounding soil, preventing the drainage board from being pulled out by the connecting plate 2.
[0017] Example 2: The difference between this example and Example 1 is that the grip 1 also includes a limiting component disposed between the connecting rod 11 and the extension rod 12 and between the two extension rods 12. The limiting component includes two limiting rings 14 fixedly fitted along the axial direction at the lower end of the extension rod 12, and a fixing ring 17 fixedly fitted along the upper end of the connecting rod 11 and the extension rod 12. A spring 15 and a collar 19 are axially spaced on the extension rod 12 between the two limiting rings 14. Multiple slots 18 are evenly provided along the circumference on the lowermost limiting ring 14 of the extension rod 12 and the two fixing rings 17. Multiple limiting plates 16 are evenly fixedly installed along the circumference at the lower end of the collar 19. The limiting plates 16 correspond one-to-one with the slots 18, and one side of the lower end of the limiting plate 16 is a slope.
[0018] Working principle: When the connecting rod 11 is connected to the extension rod 12 and the adjacent extension rod 12 by threads, the extension rod 12 is rotated. At this time, the side of the groove 18 of the fixing ring 17 contacts the inclined surface of the limiting plate 16. Due to the guiding effect of the inclined surface, the fixing ring 17 applies an upward component force to the limiting plate 16, pushing the collar 19 to slide upward along the extension rod 12 and compressing the spring 15. As the threads continue to tighten, the fixing ring 17 and the corresponding limiting ring 14 gradually approach each other. When the threads reach the tightened state, the groove 18 of the fixing ring 17 and the groove 18 of the limiting ring 14 are axially aligned. The spring 15 releases its elastic potential energy, pushing the collar 19 to move downward, so that the limiting plate 16 is simultaneously inserted into the groove 18 of the fixing ring 17 and the limiting ring 14, completing the pre-fixing of the limiting position.
[0019] During the insertion process, if the threaded connection tends to loosen in the reverse direction due to vibration, the vertical surface of the limiting plate 16 away from the inclined plane will be in close contact with the vertical side of the slot 18. Since the vertical surface has no guiding effect and the preload of the spring 15 keeps the limiting plate 16 in the slot 18, a rigid limit is formed, which effectively prevents the thread from rotating in the reverse direction and has a significant anti-loosening effect. When it is necessary to disassemble the extension rod 12, pull the collar 19 upward to compress the spring 15, so that the limiting plate 16 is disengaged from the slot 18, and the thread can be disassembled by rotating the component in the reverse direction. The operation is flexible and does not affect the length adjustment function of the device.
[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
