Description

Technical Field

[0001] The present invention belongs to the technical field of geocells, and particularly relates to a geocell laying device and a laying method. Background Art

[0002] A geocell is a three-dimensional reticular cell structure formed by high-molecular materials such as HDPE, PP, and PET through processes such as welding, plugging, riveting, and injection molding at the joints, and has the characteristics of being able to stretch freely and can be folded during transportation. During construction, it is stretched into a net shape, and then loose materials such as soil, gravel, and concrete are filled into the cells to form a structure with strong lateral restraint and high stiffness, having relatively high lateral restraint and anti-slip ability, and can effectively enhance the bearing capacity of the roadbed and disperse the load.

[0003] Currently, when laying geocells, it mainly relies on workers standing around to stretch the geocells into a net shape, then fixing them with anchor rods around, and then filling and compacting the filler in the geocell grids. In the current construction process of geocell laying, there are the following problems: First, during the manual tensioning process, affected by factors such as personnel, products, and construction sites, the tensioning effect of the geocells is greatly affected. Especially when the geocell grid size is small, the ribband is thick, the ribband is high, and there is loose sand and soil at the construction site, it is very difficult for workers to tension it in place, seriously affecting the reinforcement and strengthening effects of the geocells. Second, a large number of anchor rods are used, resulting in high material costs and high manual labor intensity. Third, there are many construction workers and low laying efficiency. Summary of the Invention

[0004] The present invention provides a geocell laying device and a laying method, aiming to solve the problems existing in the process of geocell laying.

A plurality of tensioning components are slidably connected to the tracks, and the tensioning components can slide freely along the tracks. The tensioning components include a detachable connecting tension rod at the front end. The tension rod is vertically arranged and is used to penetrate into the geocell to provide tensile force.

[0007] Further, the track is in a T shape, and a plurality of support seats are arranged below the track. The track is fixed on the support seats, and the support seats are fixed on the ground.

[0008] Further, there are multiple groups of the tracks, and two adjacent tracks on one side are fixed to each other through fixing members.

[0009] Further, the track includes an integrally formed horizontal plate and a vertical plate. The horizontal plate is located in the middle of the vertical plate; the support seat is fixed to the horizontal plate, and the tensioning component is connected to the vertical plate.

[0010] Further, the tensioning assembly includes a horizontally arranged upper support bar and a lower support bar, and the upper support bar and the lower support bar are fixedly connected by a first vertical connecting rod; the tail ends of the upper support bar and the lower support bar are respectively provided with a first roller, and the two first rollers are in contact with the outer surface of the vertical plate; a second roller is arranged on the first vertical connecting rod, and a horizontal groove is formed in the inner surface of the vertical plate along the length direction of the guide rail, and the second roller is clamped in the groove.

[0011] Further, the front ends of the upper support bar and the lower support bar are both fixedly connected with a Z-shaped extension bar through a screw, and a stretching rod slot is arranged at the front end of the extension bar, and the stretching rod is arranged in the stretching rod slot.

[0012] Further, a second vertical connecting rod is also fixedly connected between the upper support bar and the lower support bar.

[0013] Further, it further includes a tensioning frame, and the tensioning frame includes a triangular frame. A connecting seat for connecting with an external towing device is arranged at the front end of the frame, a horizontal guide plate is arranged at the rear end of the frame, the structure of the guide plate is the same as that of the guide rail, and a plurality of tensioning assemblies are slidably connected to the guide plate.

[0014] A laying method of a geocell, adopting the above-mentioned geocell laying device, includes the following steps:

[0015] (1) Fixing the starting end anchor bolt: Fix the starting end anchor bolt at the starting point of the geocell laying. The number of the starting end anchor bolts is equal to the number of cells in the width direction of the geocell, and the distance between adjacent starting end anchor bolts is equal to the length of the cell diagonal;

[0016] (2) Fixing the track: Fix the track on the roadbed according to the laying width and the starting point of the geocell, so that the distance between the two stretching rods is equal to the laying width of the geocell;

[0017] (3) Hanging the net: Hang the front end of the geocell on the starting end anchor bolt, hang the two sides of the geocell on the stretching rods of the track tensioning assembly respectively, and hang the tail end of the geocell on the stretching rod of the tensioning frame tensioning assembly;

[0034] As Figure 2 and 3 As shown in the figure, a number of tensioning components 2 are slidably connected to the track 1, and the tensioning components 2 can slide freely along the track 1. The tensioning component 2 includes a horizontally arranged upper support bar 201 and a lower support bar 202, and the upper support bar 201 and the lower support bar 202 are fixedly connected through a first vertical connecting rod 203. First rollers 205 are connected to the tails of the upper support bar 201 and the lower support bar 202, and the two first rollers 205 are in contact with the outer surface of the vertical plate 101. A second roller 204 is provided on the first vertical connecting rod 203, and a horizontal groove is provided along the length direction of the guide rail on the inner surface of the vertical plate 101, and the second roller 204 is clamped in the groove.

[0035] A second vertical connecting rod 206 is also connected between the upper support bar 201 and the lower support bar 202, and the second vertical connecting rod 206 is used to improve the connection strength between the upper support bar 201 and the lower support bar 202. The fronts of the upper support bar 201 and the lower support bar 202 are fixedly connected with Z-shaped extension bars 207 through screws. A C-shaped tension rod slot 209 is provided at the front end of the extension bar 207, and a tension rod 209 is vertically inserted into the tension rod slot 209. The tension rod 209 is used to provide tensile force when inserted into the geocell. There are various specifications for the extension bars 207, and the bending heights of different specifications of the extension bars 207 are different, and the distances between the fronts of the corresponding two extension bars 207 are also different. During construction, extension bars 207 of different specifications are installed to facilitate corresponding to geocells of different heights.

[0036] It also includes a tensioning frame 5. The tensioning frame 5 includes a triangular frame. A connecting seat 8 connected to an external towing device is provided at the front end of the frame, and a horizontal guide plate 6 is provided at the rear end of the frame. The structure of the guide plate 6 is the same as that of the guide rail, and a number of tensioning components 2 are also slidably connected to the guide plate 6.

[0037] As Figure 4 As shown in the figure, the usage method of the above geocell laying device includes the following steps:

[0038] (1)Fixing the starting - end anchor bolts: First, determine the starting - end and width of the geocell laying according to the design drawing and draw a line. Then, fix the starting - end anchor bolts 7 at the starting point of the geocell. The number of starting - end anchor bolts 7 is equal to the number of cells in the width direction of the geocell. Each starting - end anchor bolt 7 corresponds to one cell, and the distance between adjacent starting - end anchor bolts 7 is equal to the length of the diagonal of the cell. After driving the starting - end anchor bolts 7 into the ground, ensure that the height of the starting - end anchor bolts 7 exposed above the ground is not less than the height of the cell.

[0039] (2)Fixing the tracks: Place the tracks 1 on the subgrade according to the laying width and starting point of the geocell, so that the distance between the two tension rods 209 is equal to the laying width of the geocell. Ensure that the two tracks 1 are parallel, then drive the anchor bolts 301 of the floor into the anchor - bolt holes of the support seat 3 to fix the tracks 1 on the foundation. Then, install the fixing plates 4 between adjacent tracks 1 to connect multiple tracks 1 on one side into a straight - line track 1.

[0040] (3)Hanging the net: Hang the front end of the geocell on the starting - end anchor bolts 7, with each cell corresponding to one starting - end anchor bolt 7. Then, hang the two sides of the geocell on the tension rods 209 of the track 1 tensioning assembly 2 respectively, and each cell also corresponds to one tension rod 209. When hanging, the staff holds the reinforcing belt by hand, inserts the tension rod 209 into the cell, and then installs the tension rod 209 into the tension - rod slot 209. Finally, hang the tail end of the geocell on the tension rod 209 of the tensioning frame 5, and the hanging steps are as above.

[0041] (4)Tensioning the geocell: Connect the external towing device to the tensioning frame 5 through the connecting seat 8, and then pull the tensioning forward to move, so as to tension and deform the geocell. During the elongation process of the geocell, the tensioning assembly 2 moves along the track 1, which is convenient to transfer the tension to each cell, so that each cell deforms uniformly until it is stretched to the predetermined length.

[0042] (5)Filling and compaction: First, fill the filler on the left and right sides of the geocell to fix the shape of the geocell. Then, a group of staff remove and move forward the tensioning assembly 2, the tensioning frame 5, and the track 1, and re - fix the track 1 for laying the next section of the geocell. Another group of staff compact the entire previous geocell. When laying the next section of the geocell, the head end of the next section of the geocell is connected to the tail end of the previous section of the geocell through a bolt, and there is no need to use the starting - end anchor bolts 7. At the same time, leave a group of staff to hang, stretch, and fix the geocell, and another group of staff to carry out the filling and compaction operation, which can improve the utilization rate of personnel and speed up the laying speed.

[0043] It should be noted that the above are only some embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
