Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a self-anchored road water-stabilizing layer template inner pull rod which is easy to install and disassemble. Background Art

[0002] Water-stabilizing layer is the abbreviation of cement-stabilized gravel layer, which is completed by using cement to consolidate gravel and compacting and curing. The mix ratio of water-stabilizing layer should be tested in the laboratory in advance to determine the cement content and the ratio of coarse and fine aggregates, and at the same time determine the maximum dry density. If the quantity is large, a water-stabilizing mixing station can be used for mixing.

[0003] Before the construction of the water-stable layer, the formwork needs to be supported and fixed. In the prior art, steel nail-anchored inner tie rods are often used to fix the road water-stable base formwork. The inner tension depends on the strength of the steel nails anchored in the underlying layer, which has the problem of insufficient inner tension. In addition, the inner tie rod uses a single transverse reinforcement to fix the formwork, which has no fulcrum when removing the formwork. The construction speed is slow, and two people are required to cooperate in the removal, which is labor-intensive. Therefore, there is an urgent need for a self-anchored road water-stable layer formwork inner tie rod that is easy to install and remove to solve the above problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the present utility model embodiment, please refer to Figures 1 to 4, a self-anchored road water-stabilizing layer template inner tie rod that is easy to install and disassemble, comprising a template 7 that is spliced ​​and laid along the length of the road edge, the template 7 is placed on the road underlying layer 10, a plurality of groups of rectangular holes 8 are opened at the center position of the height of the template 7, and the plurality of groups of rectangular holes 8 are arranged at equal intervals along the horizontal length direction of the template 7, gravel 9 is laid in the space between the template 7 and the road underlying layer 10 on both sides, and an inner tie structure for fixing the template 7 is arranged between the side wall of the template 7 and the road underlying layer 10;

[0021] The inner pulling structure includes a rod body 3, and an anchor end circular ring 1 is provided at one end of the rod body 3 away from the template 7. A fixing steel nail 6 for fixing the rod body 3 is provided inside the anchor end circular ring 1. The fixing steel nail 6 is inserted into the lower supporting layer 10 of the road. The bottom of the fixing cap on the top of the fixing steel nail 6 abuts against the top of the anchor end circular ring 1. A rectangular ring 5 is provided at the other end of the rod body 3, and the rectangular ring 5 abuts against the outer wall of the template 7. An inner supporting cross bar 4 is provided on the rod body 3, and the inner supporting cross bar 4 abuts against the inner wall of the template 7. A self-anchoring cross bar 2 is provided on the rod body 3, and the self-anchoring cross bar 2 is located inside the gravel 9.

[0022] Place the template 7 on the road sub-layer 10, hold the rod body 3, pass the rectangular ring 5 horizontally through the rectangular hole 8 and rotate it 90°, the inner support cross bar 4 and the rectangular ring 5 will clamp the template 7 to prevent the template 7 from shaking or falling over, pass the fixing steel nail 6 through the anchor end ring 1 and insert it into the road sub-layer 10, so as to fix the rod body 3 and the self-anchoring cross bar 2 on the top of the road sub-layer 10, and the installation is completed.

[0023] In this embodiment, the rod body 3 and the self-anchoring cross bar 2 are buried when the road water-stabilizing base layer is paved. The self-anchoring cross bar 2 generates a self-anchoring tension, which can withstand the extrusion pressure exerted on the template 7 during the compaction process, thereby ensuring the compaction degree and line shape of the edge of the water-stabilizing layer. The edge line shape of the water-stabilizing layer is straight and beautiful.

[0024] As an embodiment of the utility model, the length of the rectangular ring 5 is smaller than the length of the rectangular hole 8 , the length of the inner support cross bar 4 is larger than the length of the rectangular hole 8 , and the length of the rectangular ring 5 is larger than the width of the rectangular hole 8 .

[0025] The length of the rectangular ring 5 is smaller than the length of the rectangular hole 8, ensuring that the rectangular ring 5 can pass through the rectangular hole 8. The length of the inner support cross bar 4 and the length of the rectangular ring 5 are both larger than the width of the rectangular hole 8, ensuring that the template 7 is located between the inner support cross bar 4 and the rectangular ring 5. The inner support cross bar 4 and the rectangular ring 5 clamp the template 7 so that the template 7 will not shake or fall over significantly.

[0026] As an embodiment of the present utility model, the rod body 3 is made of cold-drawn steel wire.

[0027] The working principle of the utility model is as follows: 1. Placing the template 7: determining the edge line of the water-stable layer on the road underlying layer 10, and placing the template 7 along the outer side of the edge line;

[0028] 2. Fixing of the template 7: Hold the rod body 3, pass the rectangular ring 5 horizontally through the rectangular hole 8, and then rotate it 90°, so that the inner support cross bar 4 and the rectangular ring 5 rotate synchronously to a vertical state with the ground. At this time, the template 7 is located between the inner support cross bar 4 and the rectangular ring 5, and the inner support cross bar 4 and the rectangular ring 5 clamp the template 7, so that the template 7 will not shake or fall over significantly;

[0029] Pass the fixing steel nail 6 through the anchor end ring 1, and use a hammer or other tool to knock the fixing steel nail 1, so that the fixing steel nail 1 is inserted into the road underlying layer 10, thereby fixing the rod body 3 and the self-anchoring cross bar 2 on the top of the road underlying layer 10;

[0030] Installing an inner tie rod at a certain distance can quickly complete the installation of the template 7;

[0031] 3. Removal of the template 7: Spread the crushed stone 9 on the road sub-layer 10, and then spread cement to stabilize the crushed stone 9. After compaction and maintenance, pry off the rectangular ring 5 with a steel chisel, or rotate it 90° to separate the template 7 from the inner tie rod, thereby completing the removal of the template 7.
