Description

Technical Field

[0001] This utility model relates to the field of support equipment technology, specifically to a support mechanism for soft soil layers. Background Technology

[0002] Soft soil refers to silt, silty soil, and some fill, miscellaneous fill, and other highly compressible soils. Soft soil is characterized by high natural water content, large natural void ratio, low shear strength, high compressibility coefficient, and low permeability coefficient. Many routine operations require the construction of support structures in soft soil layers. Examples include temporary walkways erected to ensure passage on silty ground and temporary solar panel supports erected on riverbanks to avoid occupying usable space. Currently, the installation of temporary support structures in soft soil layers often requires manual placement of the support structure into the soft soil layer for installation, a process that is extremely inconvenient for construction workers. Summary of the Invention

[0003] The present invention aims to solve one of the technical problems mentioned above by providing a support mechanism for soft soil layers, which allows operators to complete the installation of the support mechanism without entering the soft soil layer.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A support mechanism for soft soil layers includes a support rod, a base, and several plates. The base is sleeved on one end of the support rod and can slide or be fixed relative to the support rod. The outer side of the support rod is provided with several locking grooves, which are spaced apart along the circumference of the support rod and are located between the base and the other end of the support rod. Several plates are rotatably mounted on the support rod and each plate is in contact with the base. One plate is installed corresponding to one locking groove, and one end of the plate extends into the locking groove, allowing the plate to abut against the bottom surface of the locking groove.

[0005] Furthermore, one end of the support rod is a multifaceted column, the base is sleeved on the multifaceted column, one side of the multifaceted column is provided with a locking groove, and a plate is installed on one side of the multifaceted column.

[0006] Furthermore, the width of the axle gradually increases in the direction away from the polyhedron, the axle extends in the direction away from the polyhedron, and the length of the axle is less than the sum of the distances from the top surface of the polyhedron to the bottom surface of the base when the base is located at the lowest position of the polyhedron.

[0007] Furthermore, a guide nut is screwed into the interior of the base, and the guide nut is slidably fitted onto one end of the support rod.

[0008] Furthermore, the support rod is recessed along its length in a guide groove, and the guide nut is provided with rollers corresponding to the guide groove.

[0009] Furthermore, the base is provided with a clamping step, and a high-strength spring washer is provided between the clamping step and the guide nut.

[0010] Furthermore, the high-strength spring pad is movably sleeved on one end of the support rod.

[0011] Furthermore, the base is provided with a screw groove and a socket groove. The screw groove extends inward from the top surface of the base and the inner side of the screw groove is threaded. The socket groove is located between the screw groove and the bottom surface of the base and communicates with the screw groove. The inner side of the base corresponding to the socket groove is a four-sided groove and contacts the support rod.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects: When using the aforementioned soft soil support mechanism, first place it in its initial state, with the base at one end of the support rod and several support plates in a retracted state. With the base facing down, throw the support rod into the soft soil layer. The base will hit the ground first, sinking into the soft soil. During this process, the base is pushed along the support rod and lifted upwards by the thrust of the soft soil. As the base continues to rise, it pushes the support plates to rotate, and the plates gradually unfold relative to the support rod. As the plates unfold, the soft soil support mechanism continues to sink into the soft soil layer, and the contact area between the plates and the soil gradually increases. During this process, the conical groove formed by the plates presses against the soft soil layer. When the plates rotate to abut against the bottom of the locking groove, or when the soft soil is sufficient to support the conical groove of the plates and no longer sinks, the soft soil support mechanism is now fixedly inserted into the silt, and the support rod can be used to erect the object to be supported. It is evident that when installing support mechanisms for soft soil layers, operators can complete the installation without entering the soft soil layer. Attached Figure Description

[0020] like Figures 1 to 3 As shown, a preferred embodiment of this utility model provides a support mechanism for soft soil layers, including a support rod 1, a base 2, and a plurality of plates 3. The base 2 is sleeved on one end of the support rod 1, and the base 2 can slide or be fixed relative to the support rod 1. The outer side of the support rod 1 is provided with a plurality of locking grooves 111, each locking groove 111 including a bottom surface that is inclined outward relative to the center line of the support rod 1; the plurality of locking grooves 111 are spaced apart along the circumference of the support rod 1, and are located between the base 2 and the other end of the support rod 1. A plurality of plates 3 are rotatably mounted on the support rod 1, and all of the plates 3 are in contact with the base 2. One plate 3 is correspondingly mounted to one locking groove 111, and one end of the plate 3 extends into the locking groove 111, and the plate 3 can abut against the bottom surface of the locking groove 111.

[0021] When using the aforementioned soft soil support mechanism, it is first placed in its initial state, with the base 2 located at one end of the support rod 1 and the several plates 3 in a retracted state. With the base 2 facing downwards, the support rod 1 is thrown towards the soft soil layer. The base 2 first touches the soft soil layer, sinking into it. During this process, the base 2 is pushed by the soft soil layer and slides along the support rod 1, rising upwards. As the base 2 continues to rise, it pushes the plates 3 to rotate, and the plates 3 gradually unfold relative to the support rod 1. As the plates 3 unfold, the soft soil support mechanism continues to sink into the soft soil layer, and the contact area between the plates 3 and the soil in the soft soil layer gradually increases. During this process, the conical groove formed by the plates 3 presses against the soft soil layer. When the plates 3 rotate to abut against the bottom surface of the locking groove 111, or when the soft soil layer is sufficient to support the conical groove of the plates 3 and no longer sinks, the soft soil support mechanism is then fixedly inserted into the soft soil layer, and the support rod 1 can be used to erect the object to be supported. It is evident that when installing support mechanisms for soft soil layers, operators can complete the installation without entering the soft soil layer.

[0022] In this embodiment, one end of the support rod 1 is a multifaceted column 11, and the base 2 is sleeved on the multifaceted column 11. Specifically, the multifaceted column 11 is a square column. The base 2 is provided with a screw groove 22 and a sleeve groove 23. The screw groove 22 extends inward from the top surface of the base 2 and the inner side of the screw groove 22 is threaded. The sleeve groove 23 is located between the screw groove 22 and the bottom surface of the base 2 and communicates with the screw groove 22. The inner side of the base 2 corresponding to the sleeve groove 23 is a four-sided groove and contacts the multifaceted column 11. A guide nut 4 has a square hole of equal size in the middle and a thread on the outer side. The guide nut 4 is screwed into the screw groove 22 of the base 2 and is slidably sleeved on the multifaceted column 11. One face of the multifaceted column 11 has a locking groove 111, and a plate 3 is rotatably mounted on one face of the multifaceted column 11. Specifically, a bearing seat 113 is installed below the locking groove 111, and a rotating shaft 114 is mounted on the bearing seat 113. A rotating seat 31 is mounted on the plate 3, and the rotating seat 31 is rotatably sleeved on the rotating shaft 114. In the initial state, the base 2 is located at the bottom end of the multifaceted column 11, and several plates 3 are in a retracted state and are all in contact with the base 2. When the base 2 slides along the multifaceted column 11 and rises upward, the base 2 pushes several plates 3 to rotate and unfold relative to the multifaceted column 11. When the base 2 slides to the bearing seat 113, the bearing seat 113 limits the base 2, at which time the plates 3 abut against the bottom surface of the locking groove 111.

[0023] In this embodiment, the support rod 1 has a guide groove 112 recessed along its length, and the guide nut 4 has rollers 5 corresponding to the guide groove 112. Specifically, the guide nut 4 has a limiting groove corresponding to the guide groove 112, and several rollers 5 are placed in the limiting groove along the length of the guide groove 112. In the initial state, under the action of gravity, the base 2 is located at the bottom of the multifaceted column 11. At this time, the rollers 5 are engaged by the limiting groove and the guide groove 112 at the bottom end of the guide groove 112, which can prevent the base 2 from detaching from the support rod 1. When the base 2 slides along the support rod 1 under force, the rollers 5 allow the guide nut 4 to slide more smoothly on the multifaceted column 11.

[0024] In this embodiment, the base 2 is provided with a clamping step 21 corresponding to the screw groove 22, and the inner side of the clamping step 21 contacts the multifaceted column 11. A high-strength spring washer 6 is provided between the clamping step 21 and the guide nut 4. Specifically, the high-strength spring washer 6 is movably sleeved on the multifaceted column 11 and located between the clamping step 21 and the guide nut 4. When the soft soil layer support mechanism is fixedly inserted into the soft soil layer, the guide nut 4 presses tightly against the high-strength spring washer 6, and the high-strength spring washer 6 can prevent the guide nut 4 from loosening.

[0025] In this embodiment, the width of the plate 3 gradually increases in the direction away from the polyhedral column 11. The plate 3 extends in the direction away from the polyhedral column 11 and the length of the plate 3 is less than the sum of the distances from the top surface of the polyhedral column 11 to the bottom surface of the base 2 when the base 2 is at the lowest position of the polyhedral column 11, so as to ensure that when the soft soil support mechanism is deployed to the soft soil layer, the base 2 can contact the soft soil layer first.

[0026] It is understandable that the support mechanism for soft soil layers can be deployed manually or by using flying equipment, such as drones or helicopters. In this case, the end of the support rod 1 that is away from the base 2 can be fixed to the flying equipment.

[0027] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
