Description

Technical Field

[0001] This utility model relates to the technical field of sandbag laying positioning guide frame, specifically a sandbag laying positioning guide frame for intertidal cofferdams. Background Technology

[0002] The intertidal zone is a transitional zone between the ocean and the land. Its most prominent feature is the periodic rise and fall of tides, which cause the area to be submerged underwater and exposed above the water surface at different times. This unique alternating wet and dry environment, coupled with the soft tidal flat geology, low bearing capacity, and difficulty in accessing large machinery, poses a huge challenge to engineering construction in this area, such as cofferdams, revetments, and artificial islands.

[0003] Sandbags are a commonly used engineering material in intertidal cofferdam projects. They have advantages such as being readily available locally, flexible in construction, having little environmental impact, and being able to adapt to foundation deformation. By stacking sandbags according to the path, location, and number of layers in the design drawings, stable temporary or permanent cofferdam structures can be formed, which can play a role in water blocking, bank protection, and siltation promotion.

[0004] When laying sandbags for cofferdams in the intertidal zone, problems such as inaccurate positioning, disordered sandbag arrangement, and uncontrolled spacing are prone to occur, resulting in insufficient stability of the cofferdam structure and risks such as leakage and collapse.

Detailed Implementation

[0036] 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.

[0037] In the embodiments, by Figure 1-5 A positioning guide frame for sandbag laying in intertidal zone cofferdams is provided, which may optionally include, but is not limited to, a bearing base 1;

[0038] Mounting component 2 is located on the upper surface of the support base 1;

[0039] The positioning assembly 3, which can be placed inside the mounting component 2, includes a positioning rod 31, which can be placed inside the mounting component 2; an insertion rod 32, which is located on the lower end face of the positioning rod 31; a rotating groove 33, which is opened on the outer side of the positioning rod 31 and is located between the positioning rods 31; a mounting groove 34, which is opened on the upper end face of the positioning rod 31; a rubber ring 35, which is located on the outer side of the positioning rod 31 and whose upper surface is flush with the upper end face of the positioning rod 31; a wire guide 36, which is located inside the rotating groove 33; and a fixing member 37, which is located inside the mounting groove 34.

[0040] This embodiment presents a positioning guide frame for intertidal zone cofferdam sandbag laying. A supporting base 1 serves as the overall support structure, placed on the intertidal zone ground to provide a stable installation foundation. An installation component 2 is fixed to the upper surface of the supporting base 1 to accommodate a positioning assembly 3. The insertion rod 32 of the positioning assembly 3 is located at the lower end face of the positioning rod 31 and can be inserted into the intertidal soil, further enhancing the stability of the positioning rod 31 and preventing positional displacement due to external forces such as tides and water flow. This provides a fixed reference point for subsequent guiding operations. The rotating groove 3 on the outer side of the positioning rod 31... The positioning rod 31 has a guide wire 36 inside, which can release the guide wire and visually mark the laying boundary, row spacing or arrangement direction of the sandbags, ensuring that the sandbags are neatly stacked according to the preset route and avoiding misalignment. The mounting groove 34 on the upper end of the positioning rod 31 has a fixing part 37, which can fix a flag with bright colors such as red or yellow. The flag has high visibility in the intertidal environment, and even in complex lighting conditions such as cloudy days, backlighting or long distances, the staff can quickly identify the position of the positioning frame, which helps to judge the accuracy of the guide wire trajectory and facilitates unified scheduling when the team is working together.

[0041] Furthermore, there are several positioning components 3, which are placed in a left-right sequence on the inside of the mounting component 2.

[0042] Preferred, such as Figure 1 As shown, four omnidirectional wheels are evenly distributed on the lower surface of the support base 1. Furthermore, depending on the actual use, the four omnidirectional wheels can be replaced with four curved sliding plates, thereby ensuring that the support base 1 can move easily on the intertidal zone.

[0043] Furthermore, such as Figure 2 As shown, the mounting component 2 in the preferred embodiment of this utility model includes a mounting frame 21 disposed on the upper surface of the support base 1; two through holes 22 respectively opened on the left and right sides of the mounting frame 21; two placement grooves 23 respectively opened symmetrically on the inner side of the mounting frame 21; and a rubber pad 24 disposed on the inner side of the lower placement groove 23.

[0044] Furthermore, the lower end of the insertion rod 32 contacts the upper surface of the rubber pad 24; the upper surface of the rubber ring 35 contacts the inner top surface of the mounting frame 21.

[0045] In this embodiment, several preferred embodiments of the mounting component 2 are provided. By fixing the mounting frame 21 to the upper surface of the support base 1, a frame structure is formed to accommodate the positioning component 3, providing vertical installation space for the positioning rod 31. Two placement slots 23 are symmetrically opened on the inner side of the mounting frame 21, which respectively limit the upper and lower parts of the positioning component 3. The lower placement slot 23 contacts the lower end of the insertion rod 32 through the inner rubber pad 24, restricting the downward displacement of the positioning rod 31; the upper placement slot 23 contacts the upper surface of the rubber ring 35 on the outer side of the positioning rod 31, restricting the upward displacement of the positioning rod 31. The displacement is prevented by bidirectional constraints from the upper and lower sides to prevent the positioning component 3 from axially moving during tidal impacts or external collisions. The rubber pad 24 on the inner side of the lower placement groove 23 contacts the lower end of the insertion rod 32. The elastic properties of the rubber material are used to buffer the downward impact force of the positioning component 3 caused by gravity or external force. The rubber ring 35 on the outer side of the positioning rod 31 contacts the inner top surface of the mounting frame 21. Similarly, the elasticity of the rubber buffers the upward force of the positioning rod 31 and fills the gap between the positioning rod 31 and the mounting frame 21. In this way, the positioning rod 31 can be stably placed between the inner sides of the two placement grooves 23.

[0046] Furthermore, such as Figure 4 As shown, the guide wire 36 in the preferred embodiment of this utility model includes a guide wheel 361, which is rotatably disposed inside the rotating groove 33; a scale guide wire 362, which is retractable and disposed on the guide wheel 361; and an angle disk 363, which is disposed outside the positioning rod 31, and the upper surface of the angle disk 363 is in contact with the lower surface of the guide wheel 361.

[0047] Furthermore, one end of the scale guide 362 of the guide member 36 is located outside the positioning rod 31 of another positioning component 3 on the right side. This allows multiple positioning components 3 to be connected in series, so that the distance between the two positioning components 3 placed on the intertidal zone can be clearly known under the action of the scale guide 362. The scale guide 362 adopts a segmented color design, which is divided into units of one meter along the length direction, and each segment is equipped with a unique color mark. In addition, fine length scales are further printed on the outer surface of each color segment. By combining the macro indication of the color segment with the micro reading of the scale mark, the length of the scale guide 362 can be quickly identified and accurately measured.

[0048] This embodiment provides several preferred embodiments of the guide wire 36. Workers can pull out the scale guide wire 362 from the guide wheel 361 and fix one end to the outside of the positioning rod 31 of the adjacent positioning component 3 on the right. This allows multiple positioning components 3 to be connected in series via the scale guide wire 362. During this process, the rotation of the guide wheel 361 ensures smooth release of the guide wire, forming a continuous straight or broken line trajectory, which directly serves as the boundary or row spacing benchmark for sandbag laying. Furthermore, by observing the number of color segments on the scale guide wire 362, workers can quickly and macroscopically determine the distance between two positioning components 3. This is suitable for rapid planning scenarios where distance accuracy requirements are not high. When it is necessary to change the laying trajectory direction, such as at the corner of a cofferdam, the scale on the angle disc 363 can visually display the angle between the current scale guide wire 362 and the positioning rod 31, ensuring that the trajectory of the scale guide wire 362 between multiple sets of positioning components 3 conforms to the preset angle requirements. This avoids sandbag misalignment caused by directional deviation, thus guiding workers to stack sandbags along a uniform trajectory and ensuring the regularity and stability of the overall structure.

[0049] Furthermore, such as Figure 5 As shown, the fixing member 37 in the preferred embodiment of this utility model includes a return spring 371, which is disposed inside the mounting groove 34, and the upper end of the return spring 371 is located below the upper end face of the positioning rod 31; a fixing rod 372, which is disposed above the return spring 371, and the outer side of the fixing rod 372 is in contact with the inner side of the mounting groove 34; a fixing groove 373, which is formed on the upper end face of the fixing rod 372; a lead screw 374, which is threadedly connected to the inner side of the fixing rod 372, and one end of the lead screw 374 is located inside the fixing groove 373; and a fixing plate 375, which is rotatably disposed on the end face of the lead screw 374 located in the fixing groove 373.

[0050] Furthermore, when the positioning rod 31 is located inside the mounting frame 21, the fixing rod 372 is located inside the upper placement groove 23, and the upper end face of the fixing rod 372 is in contact with the inner top surface of the placement groove 23.

[0051] In this embodiment, several preferred embodiments of the fixing member 37 are given. When the positioning rod 31 is placed between the two placement slots 23 of the mounting frame 21, the fixing rod 372 is pressed into the mounting slot 34 of the positioning rod 31. At the same time, the return spring 371 inside the mounting slot 34 is compressed. The rebound force of the return spring 371 keeps the fixing rod 372 firmly against the top surface of the upper placement slot 23. In conjunction with the rubber ring 35 on the outside of the positioning rod 31, the stability of the positioning rod 31 in the mounting frame 21 is further enhanced. At the same time, the operator can place a brightly colored flag into the fixing slot 373. When the screw 374 is rotated clockwise, the fixing plate 375 moves towards the inner wall of the fixing slot 373. Move the flag until it is firmly clamped between the fixing plate 375 and the inner wall of the fixing groove 373, thus securing the flag securely. Rotating the screw 374 in the opposite direction will release the flag, making it easy to replace or adjust. The rotatable design of the fixing plate 375 ensures that it always maintains a surface fit when in contact with the flag, avoiding excessive local pressure that could damage the flag. It also enhances the stability of the clamping, so that even if the positioning rod 31 is slightly shaken by strong winds or tides, the flag is not easy to fall off. This allows staff to quickly identify the position of the positioning component 3 by the bright flag, even at a distance or under complex lighting conditions, to help determine whether the trajectory formed by the scale guide 362 is accurate, thereby improving team collaboration efficiency.
