Description

Technical Field

[0001] This utility model relates to the field of plastic drainage board anchoring technology, specifically a plastic drainage board anchoring device. Background Technology

[0002] Plastic drainage boards, also known as plastic drainage strips, come in various shapes such as wavy and harmonica-shaped. The core is an extruded plastic core board, which serves as the skeleton and channel of the drainage strip. Its cross-section is a parallel cross, and both sides are wrapped with non-woven geotextile as a filter layer. The core strip provides support and drains water that seeps into the filter layer upwards. It is an excellent vertical channel for soft soil foundation treatment using drainage consolidation methods for saturated cohesive soils such as silt, silty soil, and fill, significantly shortening the consolidation time of soft soil.

[0003] The conventional method for installing plastic drainage boards involves placing the boards inside an insertion machine, inserting the machine to a predetermined depth in the soft soil foundation, and then removing the machine, leaving the drainage boards in the foundation. Because soft soil and silt are slippery, the friction between the drainage boards and the soil is low after insertion. When the insertion machine is pulled out, a section of the board may be pulled out, a phenomenon known as "return pull." Due to this, the drainage boards often fail to reach the designed depth, affecting the effectiveness of subsequent vacuuming operations in the soft soil foundation treatment. Therefore, during the installation of plastic drainage boards, pile shoes are used at the bottom of the boards to enhance the connection between the boards and the soil.

[0004] The commonly used pile shoe is made of a steel plate with two holes on its surface. Then, a wire is passed through the two holes and wound to form a ring. When in use, the bottom end of the plastic drainage board is simply passed through the wire and bent. The operation is simple and convenient. However, in actual use, the friction between the bent plastic drainage board and the wire is small. When pulling out the guide tube of the insertion plate machine, there is still a situation where the plastic drainage board and the wire are misaligned, resulting in a deviation in the installation depth of the plastic drainage board. Based on this, a plastic drainage board anchoring device is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a plastic drainage board anchoring device in order to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic drainage board anchoring device, comprising an anchoring plate and through holes, wherein two through holes are provided, the two through holes being symmetrically opened at both ends of the top of the anchoring plate and penetrating the bottom of the anchoring plate, the anchoring plate being connected to a steel wire ring through the through holes, the steel wire ring being elliptical in shape, the steel wire ring being used to provide support for the bottom bending hook of the plastic drainage board, the anchoring plate having a punched opening in the middle area of ​​the two through holes, the inner wall of the punched opening having a first 7-shaped clamping plate and a second 7-shaped clamping plate respectively fixed on both sides, the first 7-shaped clamping plate and the second 7-shaped clamping plate being used to make the plastic drainage board bend near the steel wire ring, thereby increasing the moving resistance of the plastic drainage board when the guide tube of the plate removal and insertion machine is pulled out.

[0007] As a further improvement of this utility model: both the first 7-shaped card plate and the second 7-shaped card plate are provided with notches and grooves, and there are multiple notches and grooves, which are staggered along the long side of the first 7-shaped card plate and the second 7-shaped card plate.

[0008] As a further embodiment of this utility model: the top horizontal portion of both the first 7-shaped card plate and the second 7-shaped card plate passes through the plane where the center of the wire ring is located, and the horizontal height of the horizontal portion of the first 7-shaped card plate is higher than the horizontal height of the horizontal portion of the second 7-shaped card plate.

[0009] As a further embodiment of this utility model, the anchor plate, through hole, punch cut, first 7-shaped clamping plate, second 7-shaped clamping plate, and notch groove are integrally formed by punching, punching, and bending processes.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] By setting up anchor plates with first and second "7" shaped clamps, the structure of the plastic drainage board located in the middle area of ​​the first "7" shaped clamp, the steel wire ring, and the second "7" shaped clamp is similar to two symmetrically distributed "S" shaped structures. When the plastic drainage board is subjected to an upward pulling force, the first and second "7" shaped clamps can further increase the movement resistance of the plastic drainage board, thereby making it less likely for the plastic drainage board to shift from the steel wire ring, thus further ensuring the stability of the plastic drainage board and effectively improving the installation depth accuracy of the plastic drainage board.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 In this embodiment of the utility model, a plastic drainage board anchoring device includes an anchoring plate 1 and through holes 2. There are two through holes 2, which are symmetrically opened at the top two ends of the anchoring plate 1 and pass through the bottom of the anchoring plate 1. The anchoring plate 1 is connected to a steel wire ring 7 through the through holes 2. The steel wire ring 7 is elliptical in shape and is used to provide support for the bottom bending hook of the plastic drainage board 8. The anchoring plate 1 has a punching opening 3 in the middle area of ​​the two through holes 2. A first 7-shaped clamping plate 4 and a second 7-shaped clamping plate 5 are fixed on both sides of the inner wall of the punching opening 3. The first 7-shaped clamping plate 4 and the second 7-shaped clamping plate 5 are used to make the plastic drainage board 8 bend near the steel wire ring 7, thereby increasing the movement resistance of the plastic drainage board 8 when the insertion machine guide tube is pulled out.

[0019] The top horizontal parts of the first 7-shaped clamping plate 4 and the second 7-shaped clamping plate 5 both pass through the plane where the center of the wire ring 7 is located. The horizontal height of the horizontal part of the first 7-shaped clamping plate 4 is higher than the horizontal height of the horizontal part of the second 7-shaped clamping plate 5.

[0020] In this embodiment, the anchoring device is used as follows:

[0021] Manually pass the bottom end of the plastic drainage board 8 through the inner side of the first 7-shaped card plate 4 and the middle of the steel wire ring 7, then bend it upwards through the inner side of the second 7-shaped card plate 5 and extend it to the outside of the second 7-shaped card plate 5. At this time, the structure of the plastic drainage board 8 in the middle area of ​​the first 7-shaped card plate 4, the steel wire ring 7 and the second 7-shaped card plate 5 is similar to two symmetrically distributed "S" shaped structures.

[0022] Then, the plastic drainage board 8 and the anchor plate 1 are sent into the depth of the soft soil foundation by the pull plate. When the bottom of the plastic drainage board 8 reaches the set depth, the pull plate resets and runs. At this time, the anchor plate 1 is unable to move upward due to soil resistance, and then provides tension to the bottom of the plastic drainage board 8 to prevent the plastic drainage board 8 from being pulled upward.

[0023] During this process, when the plastic drainage board 8 is subjected to an upward pulling force, it will be subject to frictional resistance from the first 7-shaped clamping plate 4 and the second 7-shaped clamping plate 5, which makes it difficult for the plastic drainage board 8 to deviate from the steel wire ring 7, thereby further ensuring the stability of the plastic drainage board 8 and effectively improving the installation depth accuracy of the plastic drainage board 8.

[0024] Please refer to this carefully. Figures 1-4 Both the first 7-shaped card plate 4 and the second 7-shaped card plate 5 are provided with notches and grooves 6. There are multiple notches and grooves 6, and the multiple notches and grooves 6 on the first 7-shaped card plate 4 and the second 7-shaped card plate 5 are staggered along the long side.

[0025] Anchor plate 1, through hole 2, punch cut 3, first 7-shaped clamping plate 4, second 7-shaped clamping plate 5, notch groove 6 are integrally formed through punching, punching and bending processes.

[0026] In this embodiment, the substrates for the first 7-shaped card plate 4 and the second 7-shaped card plate 5 can be formed by punching out the punching holes 3 and notches 6 in sequence on the anchor plate 1. After that, the substrates can be bent to form the first 7-shaped card plate 4 and the second 7-shaped card plate 5. The overall processing technology is simple and easy to improve the processing and production based on the existing production technology, thus facilitating the promotion of production.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
