Description

Technical Field

[0001] The utility model belongs to the technical field of geotechnical support, and specifically relates to a bidirectional steel-plastic geogrid. Background Art

[0002] Geogrid is a main geosynthetic material. Compared with other geosynthetics, it has unique properties and functions. Geogrid is often used as reinforcement material for reinforced soil structures or reinforcement material for composite materials. Geogrid is divided into four categories: plastic geogrid, bidirectional steel-plastic geogrid, glass fiber geogrid and polyester geogrid.

[0003] Among them, the bidirectional steel-plastic geogrid is made of high-strength steel wire, which is specially treated, mixed with polyethylene or polypropylene, and added with other additives. It is extruded to become a composite high-strength tensile strip with a rough embossed surface.

[0004] During the laying process of the geogrid, the paving surface of the geogrid should be relatively flat. In order to prevent longitudinal skew, it is necessary to first draw a white line or hanging line on the paving layer according to the width, and then start paving. Then fix the ends of the grid with iron nails. After fixing the ends of the grid, use a paving machine to slowly pull the grid forward. After each paving distance, it is necessary to manually tighten and straighten it until one roll of grid is laid before laying the next roll.

[0005] Although the above-mentioned existing grille laying method can also lay the grille relatively flat, the grille needs to be straightened many times, and workers need to repeat the straightening operation many times. The construction workers have a large workload and the construction efficiency needs to be further improved. In view of this, the present utility model is specially proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a bidirectional steel-plastic geogrid which can overcome the above problems or at least partially solve the above problems.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: a bidirectional steel-plastic geogrid, including a bidirectional grid, and also including: a first fixed column and a second fixed column, which are respectively arranged at the two ends of the bidirectional grid; the first fixed column and the second fixed column are both provided with limiting grooves, and the two ends of the bidirectional grid are respectively inserted into the limiting grooves of the first fixed column and the second fixed column; a limiting component for fixing the two ends of the bidirectional grid in the limiting grooves of the first fixed column and the second fixed column respectively, is installed on the first fixed column and the second fixed column; a laser transmitter and a laser receiver used in conjunction with each other are respectively rotatably connected to the ends on the same side of the first fixed column and the second fixed column.

[0008] Furthermore, the limiting assembly includes a locking bolt and a clamping plate, the locking bolt is equidistantly connected to the first fixing column and the second fixing column through threads, the clamping plate is slidably connected in the limiting groove, and the end of the locking bolt extending into the limiting groove is rotatably connected to the clamping plate.

[0009] Furthermore, an embedding groove is provided on the first fixing column and the second fixing column at a position close to the screwing end of the locking bolt, and the locking bolt is embedded in the embedding groove.

[0010] In order to improve the limiting effect of the pressing plate on the bidirectional grille, further, a non-slip pad is provided on one side of the pressing plate adjacent to the bidirectional grille.

[0011] In order to facilitate fixing of the first fixing column, further, a plurality of fixing ears are equidistantly fixedly connected to a side of the first fixing column away from the bidirectional grille.

[0012] In order to improve the efficiency of laying the bidirectional steel-plastic geogrid, further, the bottoms of the laser transmitter and the laser receiver are fixedly connected with counterweight blocks.

[0013] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model uses the first fixed column, the second fixed column, the limit assembly, the laser transmitter and the laser receiver and other components in coordination. During the laying of the bidirectional grid, compared with the prior art, there is no need to manually tighten and straighten the bidirectional grid every time a certain distance is laid. The bidirectional steel-plastic geogrid can be tightened and straightened when the bidirectional grid is fully unfolded, which can not only ensure the straightening effect, but also greatly reduce the workload of construction workers, effectively improving construction efficiency.

[0014] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0021] Embodiment 1:

[0022] Reference Figure 1-Figure 3 A bidirectional steel-plastic geogrid comprises a bidirectional grid 1, and further comprises: a first fixing column 2 and a second fixing column 3, which are respectively arranged at the two ends of the bidirectional grid 1; a limiting groove 4 is provided on the first fixing column 2 and the second fixing column 3, and the two ends of the bidirectional grid 1 are respectively inserted into the limiting grooves 4 of the first fixing column 2 and the second fixing column 3; a limiting component for fixing the two ends of the bidirectional grid 1 in the limiting grooves 4 of the first fixing column 2 and the second fixing column 3, respectively, is installed on the first fixing column 2 and the second fixing column 3; a laser transmitter 5 and a laser receiver 501 used in conjunction with each other are respectively rotatably connected to the ends on the same side of the first fixing column 2 and the second fixing column 3.

[0023] The limiting assembly includes a locking bolt 401 and a clamping plate 402. The locking bolt 401 is equidistantly connected to the first fixing column 2 and the second fixing column 3 through threads. The clamping plate 402 is slidably connected in the limiting groove 4. The end of the locking bolt 401 extending into the limiting groove 4 is rotatably connected to the clamping plate 402.

[0024] After the bidirectional steel-plastic geogrid is produced and needs to be rolled up for subsequent storage or transportation, the staff first inserts the two ends of the bidirectional grid 1 into the limiting grooves 4 of the first fixing column 2 and the second fixing column 3 respectively, and then rotates the locking bolt 401 to make the locking bolt 401 drive the clamping plate 402 to move downward until the clamping plate 402 is tightly attached to the end of the bidirectional grid 1, thereby completing the operation of installing the first fixing column 2 and the second fixing column 3 to the end of the bidirectional grid 1, and finally the second fixing column 3 can be rotated to roll up the bidirectional grid 1.

[0025] When the bidirectional geogrid needs to be used, the staff first transports the bidirectional geogrid to the ground where the bidirectional geogrid needs to be laid, and then fixes the first fixing column 2 first, and then the bidirectional grid 1 can be unfolded, so that the first fixing column 2 and the second fixing column 3 are respectively located at the two ends of the unfolded bidirectional grid 1, and then the laser transmitter 5 and the laser receiver 501 can be turned on, and the laser transmitter 5 and the laser receiver 501 are rotated to adjust the position of the transmitting end and the receiving end. When the laser receiver 501 cannot receive the laser emitted by the laser transmitter 5, it indicates that the bidirectional grid 1 is skewed, and then the staff can pull the second fixing column 3 outward to suspend and tighten the bidirectional grid 1, and then the bidirectional grid 1 can be straightened by the second fixing column 3. When the laser receiver 501 receives the laser emitted by the laser transmitter 5, it indicates that the bidirectional grid 1 has been straightened, and then the next step of operation, such as covering with soil, can be performed.

[0026] After the soil covering is completed, the locking bolt 401 can be rotated in the opposite direction to separate the pressing plate 402 from the bidirectional grille 1, and then the first fixing column 2 and the second fixing column 3 can be removed from the bidirectional grille 1 for recycling, which effectively saves the waste of resources.

[0027] It should be noted that in actual use, the first fixing column 2 and the second fixing column 3 can be made of heavy metal, so that when the two-way grille 1 is unfolded, the first fixing column 2 and the second fixing column 3 can limit the two-way grille 1, thereby preventing the two-way grille 1 from curling and bending under the action of its own elasticity after unfolding, thereby affecting the fit to the ground.

[0028] It should also be noted that the laser transmitter 5 and laser receiver 501 used in the bidirectional steel-plastic geogrid are both universal standard parts or parts known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0029] Embodiment 2:

[0030] Reference Figure 1-Figure 3 , a bidirectional steel-plastic geogrid, which is basically the same as Example 1, and further: an embedding groove 403 is opened on the first fixing column 2 and the second fixing column 3 near the screwing end of the locking bolt 401, and the locking bolt 401 is embedded in the embedding groove 403. Through the setting of the embedding groove 403, when the staff tightens the locking bolt 401 into place, the screwing end of the locking bolt 401 can be located in the embedding groove 403, thereby ensuring the smoothness of the surface of the first fixing column 2 and the second fixing column 3.

[0031] An anti-skid pad 404 is provided on one side of the clamping plate 402 adjacent to the bidirectional grille 1. The anti-skid pad 404 can increase the friction between the clamping plate 402 and the bidirectional grille 1, so that the clamping plate 402 can more stably limit and fix the end of the bidirectional grille 1.

[0032] Embodiment 3:

[0033] Reference Figure 1-Figure 3 , a bidirectional steel-plastic geogrid, which is basically the same as Example 2, and further: a first fixing column 2 is equidistantly fixedly connected to a side of the bidirectional grid 1 away from the first fixing column 2 with a plurality of fixing ears 201. By arranging the fixing ears 201 on the first fixing column 2, when the bidirectional grid 1 is unfolded and laid, it is necessary to fix one end of it first. At this time, the ground bolt can be inserted into the fixing ear 201, and the ground bolt can be sunk into the ground, so that one end of the bidirectional grid 1 can be fixed by the first fixing column 2. Then, when the bidirectional grid 1 is subsequently tensioned and positioned, the staff only needs to pull the second fixing column 3 to tension the bidirectional grid 1. The whole process can be completed by only one staff member, which effectively reduces the labor cost.

[0034] The bottom of the laser emitter 5 and the laser receiver 501 are fixedly connected with a counterweight block 502. Through the setting of the counterweight block 502, the center of gravity of the laser emitter 5 and the laser receiver 501 can be lowered, so that when the bidirectional grid 1 is fully unfolded and tightened, it can be in a face-to-face state, thereby eliminating the need for workers to manually rotate and adjust the laser emitter 5 and the laser receiver 501, effectively improving the efficiency of laying the bidirectional steel-plastic geogrid and reducing the workload of the workers.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
