DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example: Figure 1-Figure 10As shown, the present invention provides a technical solution for a ditch reinforcement device with adjustable angle and extendable for land reclamation, comprising a mesh (33), a metal part (17) and two ground nails (15), a clamping assembly is installed on one side of the mesh (33), five fixing plates (11) are arranged inside the fixing frame (1), both sides of the fixing plate (11) are rotatably connected with mounting short shafts (10), one end of the mounting short shaft (10) away from the fixing plate (11) is fixedly connected to the inner wall of the fixing frame (1), two circular grooves (12) are provided on the fixing plate (11), four square grooves (16) are provided on both sides of the fixing frame (1), an extension frame (3) is slidably installed on one end of the fixing frame (1), an external frame (7) is fixedly installed on the other end of the fixing frame (1), two square vertical grooves (20), two guide grooves (21) and two arc grooves (22) are provided on one side of the fixing frame (1), and the clamping assembly is arranged inside one of the guide grooves (21).

[0033] Specifically, limiting grooves (4) are provided on both sides of the interior of the fixing frame (1), and limiting protrusions (5) are provided inside the two limiting grooves (4). Figure 1 As shown, the limiting protrusion (5) can slide back and forth inside the limiting groove (4), one limiting protrusion (5) is fixedly connected to one end of the extension frame (3), and the other limiting protrusion (5) is fixedly connected to the other end of the extension frame (3). Under the action of the two limiting protrusions (5), the U-shaped extension frame (3) can slide back and forth on the fixed frame (1). Since the extension frame (3) is partially inserted into the two limiting grooves (4) and is in an interference fit state with the fixed frame (1), it is necessary to apply a certain force to the extension frame (3) before the extension frame (3) can slide on the fixed frame (1). The distance between the two threaded holes (6) opened on the top of the extension frame (3) and the fixed frame (1) is adjusted, so that the length of the mounting frame composed of the fixed frame (1) and the extension frame (3) is adjusted;

[0034] An external frame (7) is fixedly mounted on one end of the fixing frame (1) away from the threaded hole 1 (6), and two threaded holes 2 (8) are provided on the top of the external frame (7). The threaded hole 1 (6) provided on the extension frame (3) in one mounting frame is aligned with the threaded hole 2 (8) provided on the external frame (7) on the other mounting frame. Figure 3 As shown, bolts of corresponding specifications are used to penetrate the aligned threaded holes 1 (6) and 2 (8) to complete the installation and fixing. After the two bolts are installed between the extension frame (3) and the external frame (7), the two mounting frames can be installed together. According to the length of the ditch slope to be reinforced, multiple mounting frames can be assembled together at the construction site to form guide rail structures of different lengths, thereby improving the flexibility and convenience of the ditch slope reinforcement construction.

[0035] Five fixing plates (11) are arranged inside the fixing frame (1), and both sides of the fixing plates (11) are rotatably connected with mounting short shafts (10), and one end of the mounting short shaft (10) away from the fixing plate (11) is fixedly connected to the inner wall of the fixing frame (1), and there is a certain friction force between the contact surface of the mounting short shaft (10) and the fixing plate (11), so that the fixing plate (11) can rotate only after receiving a certain force. The fixing frame (1) is placed on the ditch slope, and four square grooves (16) are opened on both sides of the fixing frame (1), and the eight square grooves (16) are symmetrically arranged in pairs, such as Figure 6 As shown, except for the rightmost fixing plate (11), both sides of the top of the other four fixing plates (11) are provided with a square groove (16), and the reserved square groove (16) is used to install the metal part (17);

[0036] Therefore, after placing the two guide rail structures on the ditch slope at a suitable distance, the staff first holds a fork consisting of two ground nails (15) and a force-bearing block (13) fixedly connected between the two ground nails (15), and inserts the two ground nails (15) of the fork through two circular grooves (12) provided on the fixing plate (11) on the right side of the fixing frame (1), and then inserts the conical part of the bottom end of the ground nail (15) into the soil. Then, force is applied to the force-bearing block (13) so that most of the ground nail (15) is inserted into the soil, the force-bearing block (13) is tightly attached to the fixing plate (11), and the fixing frame (1) is pre-fixed. The multiple fixing frames (1) in the guide rail structure are fixed according to the law, and the two guide rail structures can be pre-fixed on the ditch slope.

[0037] When the soil quality of the ditch slope is good and can be used to plant green plants and consolidate the soil, after pre-fixing the two guide rail structures to the ditch slope, the multiple fixing plates (11) are directly fixed by multiple forks, so that the guide rail structure can be fixed to the ground, and a weight-reducing slot (9) is opened at the bottom of the fixing frame (1). The weight-reducing slot (9) reduces the weight of the fixing frame (1) and provides a channel for the ground nails (15) to be inserted into the soil. The weight-reducing slot (9) can also meet the requirements of the ground nails (15) passing through when the fixing plate (11) is rotated to different angles, so that the multiple ground nails (15) can be inserted into the soil in different directions to avoid hard objects, and can improve the gripping force generated by the cooperation of the multiple ground nails (15), thereby ensuring the stability of the installation of the fixing frame (1). Rubber pads (2) are fixedly connected to both sides of the top of the fixing frame (1), and the rubber pads (2) have a certain elasticity to reduce the damage caused by contact between people and the fixing frame (1);

[0038] Then, the clamping assembly passes the mesh (33) through the guide rail structure to reinforce the ditch slope. The specific steps are as follows:

[0039] First, take out the clamping assembly. A clamping cavity (26) is provided on one side of the guide round rod (25) in the clamping assembly. A clamping shaft (27) is provided inside the clamping cavity (26). A plurality of thin rods (29) are fixedly connected to the top of the clamping shaft (27). The pressure plate (28) is fixedly connected to the tops of the plurality of thin rods (29). The tops of the plurality of thin rods (29) all penetrate the guide round rod (25) and have a certain friction force with the guide round rod (25). Therefore, when the pressure plate (28) and the clamping shaft (27) are not subjected to force, the position of the clamping shaft (27) remains in the existing state.

[0040] Subsequently, after one side of the mesh (33) is inserted into the material clamping cavity (26) to a suitable length, the guide round rod (25) and the pressure plate (28) are held, and the pressure plate (28) is used to push the clamping shaft (27) downward through a plurality of thin rods (29), so that the clamping shaft (27) is pressed onto the mesh (33), and the mesh (33) is clamped and fixed inside the material clamping cavity (26);

[0041] Subsequently, the guide round rod (25) and the pressure plate (28) are held tightly in a posture where the pressure plate (28) is on top and the guide round rod (25) is on the bottom, and the two guide grooves (21) are symmetrically arranged at both ends of one side of the fixing frame (1), and the two arc grooves (22) are symmetrically arranged at both ends of one side of the fixing frame (1), the guide groove (21) is arranged at the bottom of the square vertical groove (20) on the same side and is connected to the square vertical groove (20), the arc groove (22) is arranged at the bottom of the guide groove (21) on the same side and is connected to the arc groove (22), the square vertical groove (20), the guide groove (21) and the arc groove (22) on the same side form a cavity that cooperates with the clamping assembly, and the staff inserts the guide round rod (25) and the pressure plate (28) into a cavity;

[0042] A second curved groove (30) is provided on one side of the top of the pressure plate (28), and a first curved groove (24) is provided on one side of the bottom of the transmission plate (23). When the pressure plate (28) enters the interior of the square vertical groove (20), the second curved groove (30) and the first curved groove (24) first come into contact. Under the action of the transmission plate (23), the pressure plate (28) is forced to move downward, thereby increasing the friction between the clamping shaft (27) and the mesh member (33), thereby ensuring that the mesh member (33) is stably clamped in the material clamping cavity (26) and moves synchronously with the guide round rod (25).

[0043] Furthermore, one end of the transmission handle (31) in the clamping assembly can pass through the arc groove (22) and then enter the inside of the guide groove (21), so the transmission handle (31) fixedly connected to the guide round rod (25) will not affect the work of inserting the guide round rod (25) and the pressure plate (28) into the cavity. After the guide round rod (25) and the pressure plate (28) are inserted into the cavity for a certain distance, one end of the transmission handle (31) moves a certain distance under the limit guide of the arc groove (22). At this time, the staff holds the outer fixed sleeve of the transmission handle (31) provided with a rubber grip (32) to pull the transmission handle (31), so that the guide round rod (25) moves inside the guide groove (21). The guide round rod (25) passes through multiple The thin rod (29) drives the pressure plate (28) to move, and the guide round rod (25) and the pressure plate (28) are relatively long, so before the forward ends of the guide round rod (25) and the pressure plate (28) enter the cavity of the adjacent new fixing frame (1), the ends of the guide round rod (25) and the pressure plate (28) are set inside the cavity of the old fixing frame (1), so the pressure plate (28) is always limited by the transmission plate (23), and the clamping shaft (27) and the guide round rod (25) are kept in a state of clamping one corner of the mesh (33) in cooperation. Therefore, two workers cooperate to operate the two clamping components to pass the two sides of the mesh (33) through the two guide rail structures, thereby completing the laying of the mesh (33);

[0044] Subsequently, after the clamping assembly passes through the last fixing frame (1), the pressure plate (28) is pulled upward, so that the clamping shaft (27) and the mesh member (33) can be separated, and the clamping assembly and the mesh member (33) can be separated, and the clamping assembly can be recovered;

[0045] Subsequently, since two square positioning grooves (35) are provided on both sides of the top of the rubber pad (2) and the top of the fixing frame (1), the square positioning groove (35) provided on the top of the rubber pad (2) corresponds to the square positioning groove (35) provided on the fixing frame (1) one by one, after a square plugging plate (34) is inserted into a square positioning groove (35) provided on one of the rubber pads (2), force is applied to the square plugging plate (34), so that the square plugging plate (34) pushes the transmission plate (23) which can only move up and down to move downward, and finally the transmission plate (23) moves downward and presses on the part of the mesh (33) provided inside the guide groove (21), so that the mesh (33) is fixed to the fixing frame (1), and since the square positioning groove (35) and the fixing frame (1) are in an interference fit, the transmission plate (23) maintains a state of clamping the mesh (33);

[0046] Finally, since the mesh (33) is a mesh structure made of a degradable material, the mesh (33) can not only reinforce the ditch slope, but also plant green plants through the holes on the mesh (33). After the green plants grow firmly, the mesh (33) is degraded under the action of the natural environment, thereby reducing environmental damage caused by ditch soil consolidation. In addition, a disassembly groove (14) is provided on one side of the force-bearing block (13). After a tool such as a crowbar or a wrench is inserted into the disassembly groove (14), the force-bearing block (13) and the ground nails (15) fixed to the force-bearing block (13) are pulled away from the soil, and the guide rail structure is disassembled and recycled from the ditch slope, thereby reducing the cost investment required for ditch reinforcement.

[0047] When the ditch slope does not meet the needs of plant growth, two guide rail structures are directly arranged on the ditch according to the shape of the metal member (17). After the guide rail structures are pre-fixed, one end of the plug-in frame (18) with a second circular groove (19) is inserted into the interior of the fixing frame (1) through the square groove (16). At the same time, the fixing plate (11) is controlled to rotate so that the plug-in frame (18) and the fixing plate (11) are fitted together, and the second circular groove (19) of the plug-in frame (18) is aligned with the first circular groove (12) of the fixing plate (11). Then, the two ground nails (15) in the fork are inserted through the second circular groove (19). 19) and the circular groove (12) are inserted into the soil, and then the plug-in frame (18), the fixing plate (11) and the fixing frame (1) can be installed to complete the installation of the plug-in frame (18). Subsequently, the other end of the plug-in frame (18) is welded and fixed to the metal member (17) to complete the installation of the metal member (17). The assembled ditch reinforcement device composed of the fixing frame (1), the extension frame (3), the external frame (7), the fixing plate (11) and the like in the present application can adapt to the installation of the mesh member (33) and the metal member (17), thereby improving the adaptability of the device.

[0048] The square grooves (16) on both sides of the first and third fixing plates (11) from left to right on the fixing frame (1) are used to install the metal piece (17) on one side of the fixing frame (1), and the square grooves (16) on both sides of the second and fourth fixing plates (11) from left to right on the fixing frame (1) are used to install the metal piece (17) on the other side of the fixing frame (1).
