[0022] Guardrail basic device embodiment:

[0023] See also Figures 1 to 4, the figure shows the preferred structure of the guardrail foundation device in this embodiment. As shown in the figure, the guardrail foundation device includes: a column 1 and a reinforcement mechanism 2. Among them, the first end of the column 1 is used to connect with the corrugated guardrail 3, and the second end of the column 1 is set on the foundation through the reinforcement mechanism 2; the foundation is a roadbed 7 or a structure 8 containing a rock layer. Specifically, one side of the first end of the column 1 is connected to the corrugated guardrail 3 through a connecting member 4, and more specifically, the first side of the connecting member 4 is connected to one side of the first end of the column 1 by bolts, and the second side of the connecting member 4 opposite to the first side is connected to the corrugated guardrail 3 by bolts. In specific implementation, the connecting member 4 can be a C-shaped steel block or other structures, and this embodiment does not impose any restrictions on this.

[0024] The reinforcement mechanism 2 is arranged on the foundation, and the second end of the column 1 is connected to the reinforcement mechanism 2 . The reinforcement mechanism 2 connects the column 1 to the foundation and reinforces the column 1 to improve the stability of the column 1 .

[0025] Preferably, the column 1 is a C-shaped steel column.

[0026] It can be seen that in the present embodiment, the first end of the column 1 is connected to the corrugated guardrail 3, and the second end of the column 1 is arranged on the foundation through the reinforcement mechanism 2. The reinforcement mechanism 2 connects the column 1 to the foundation, ensuring a stable connection between the column 1 and the foundation, thereby improving the stability of the column 1. In addition, the reinforcement mechanism 2 can reinforce the column 1, ensuring the firmness and reliability of the column 1, thereby improving the stability and safety of the corrugated guardrail 3, and solving the problem of poor stability of the column directly fixed on the roadbed in the prior art.

[0027] See also Figure 1 and Figure 2 In the above embodiment, when the foundation is a roadbed 7 containing a rock layer, the roadbed 7 is a shallow roadbed, and the reinforcement mechanism 2 is a column 21 made of concrete. The shape of the column 21 can be a rectangular parallelepiped or other shapes, and this embodiment does not impose any restrictions on this. The side wall of the column 21 is set to a sawtooth shape to improve the bite degree when the column 21 contacts the soil, ensuring that the column 21 and the soil are firmly engaged. In addition, the column 21 is set on the roadbed 7, and the second end of the column 1 is inserted into the interior of the column 21. Specifically, the bottom ( Figure 1 The lower part shown in the figure) is arranged on the roadbed 7, and the column 1 is provided from the top of the column 21 ( Figure 1 The upper part shown in the figure) is inserted into the interior of the column 21.

[0028] The column 1 is located at the center of the column 21 , and the depth of the column 1 in the column 21 is equal to the height of the column 21 .

[0029] The column 21 can be cast on site or prefabricated. However, no matter which manufacturing method is used, when manufacturing the column 21, a template is first set up, and a plurality of angle steels are welded on the inner wall of the template. The angle steels are sequentially arranged along the height direction of the template to form a sawtooth shape. After the template is set up, the column 1 is inserted into the inside of the template, and then concrete is poured into the inside of the template. After the concrete is cured, the column 1 and the column 21 are integrated, and the side wall of the column 1 is sawtooth-shaped.

[0030] When the column 21 is cast on site, the column 21 can be connected to the roadbed 7 when pouring concrete. When the column 21 and the column 1 are prefabricated, a foundation pit is excavated from the road surface to the roadbed, and the column 21 and the column 1 are prefabricated as a whole and placed in the foundation pit, and the soil layer is backfilled, wherein the soil layer is filled in layers, and the column 21 is fixed by compacting the soil layer, so that the column 21 is stably connected to the roadbed 7. In addition, the side wall of the column 21 is serrated, which can increase the bite with the surrounding soil, so that the column 21 and the soil are firmly and stably connected.

[0031] When the column 21 and the column 1 are prefabricated, a hook is provided on the portion of the column 1 outside the column 21, or a hook is provided on the side of the column 21 away from the roadbed 7 (the top surface of the column 21). In this way, the column 21 and the column 1 are hoisted together onto the roadbed 7 by the hook. In addition, the column 21 and the column 1 are prefabricated, which reduces the complexity of on-site operations, and can be prefabricated and maintained in a centralized factory, thereby ensuring production quality.

[0032] Preferably, the column 1 is located at the center of the column 21, and the depth of the column 1 in the column 21 is equal to the height of the column 21; and / or, the part of the column 1 outside the column 21 is provided with a hook, or the side of the column 21 away from the roadbed 7 is provided with a hook.

[0033] In specific implementation, the cross-sectional size of the column 21 is 350 mm×350 mm, and the concrete grade of the column 21 is C30.

[0034] In this embodiment, the column 1 is a C-shaped steel column, and its specific parameters are a C-shaped column 149×110 with a diameter of 1330-1530 mm and a thickness of 4.3 mm.

[0035] It can be seen that in this embodiment, when the foundation is a roadbed 7 containing a rock layer, that is, the roadbed 7 is a shallow roadbed, since the filling layer is too low, there are soft rocks or hard rocks at a certain depth below the ground of the roadbed 7 and construction cannot be carried out, then a column 21 made of concrete is used, and the side wall of the column 21 is set to a serrated shape, which can effectively increase the bite between the column 21 and the soil. The setting of the column 21 can ensure that the column 1 is stably set on the roadbed 7, thereby improving the stability of the column 1, and the structure of the reinforcement mechanism 2 is simple and easy to implement.

[0036] See also Figure 3 and Figure 4 In the above embodiment, when the foundation is a structure 8, the structure 8 may be a culvert / channel structure, and the reinforcement mechanism 2 includes: a reinforcement column 22 made of concrete and a reinforcement assembly 23. The bottom of the reinforcement column 22 ( Figure 3 The lower part shown in the figure is arranged on the structure 8, and part of the reinforcement component 23 is arranged inside the reinforcement column 22. The reinforcement component 23 is used to connect the reinforcement column 22 with the structure 8 to further ensure the stable connection between the reinforcement column 22 and the structure 8, and the reinforcement component 23 also connects the reinforcement column 22 with the column 1.

[0037] The reinforcement assembly 23 may include: four embedded bars 231, a reinforcement assembly and a connection assembly. Part of each embedded bar 231 is disposed in the structure 8, and the other part of each embedded bar 231 is disposed in the reinforcement column 22. Specifically, half of the length of each embedded bar 231 is disposed in the structure 8, and the other half is disposed in the reinforcement column 22. In specific implementation, each embedded bar 231 may be pre-embedded in the structure 8, and the reinforcement column 22 is cast in situ.

[0038] The reinforcement component is placed in the reinforcement column 22 , and the reinforcement component is connected to each embedded rib 231 .

[0039] Part of the connecting assembly is placed inside the reinforcement column 22 and connected to the reinforcing assembly, and another part of the connecting assembly is placed outside the reinforcement column 22 and connected to the column 1 .

[0040] The reinforcement assembly may include: four vertical steel bars 232, two connecting bars 233 and a plurality of stirrups 234. Among them, the four embedded bars 231 are distributed in a quadrilateral.

[0041] The four vertical steel bars 232 are all placed inside the reinforcement column 22. The four vertical steel bars 232 correspond to the four embedded bars 231 one by one. The first end ( Figure 3 The lower end shown in FIG. 2 is connected to the corresponding embedded reinforcement 231, and the second ends ( Figure 3 The upper end shown in the figure) is toward the top of the reinforcement column 22 ( Figure 3The upper portion shown extends from the top.

[0042] The two connecting ribs 233 are both placed inside the reinforcement column 22, and the two connecting ribs 233 are arranged in parallel. Each connecting rib 233 is transversely arranged between the second ends of the two vertical steel bars 232. Specifically, one of the connecting ribs 233 is transversely arranged between the second ends of two of the vertical steel bars 232, and the connecting rib 233 is connected to the second ends of the two vertical steel bars 232. Another connecting rib 233 is transversely arranged between the second ends of the other two vertical steel bars 232, and the connecting rib 233 is connected to the second ends of the two vertical steel bars 232. Each connecting rib 233 can be a U-shaped steel bar of Φ12.

[0043] Each stirrup 234 is placed inside the reinforcement column 22, each stirrup 234 is arranged outside each vertical steel bar 232, and each stirrup 234 is arranged along the height direction of the vertical steel bar 232 ( Figure 3 More preferably, each stirrup 234 is evenly distributed along the height direction of the vertical steel bar 232. In this embodiment, there are three stirrups 234. Each stirrup 234 can fix each vertical steel bar 232 and improve the stability of each vertical steel bar 232.

[0044] The portion of the connecting assembly disposed within the reinforcing column 22 is connected to the connecting rib 233 .

[0045] In specific implementation, when the connecting bar 23 is a U-shaped steel bar, the two ends of each connecting bar 233 are overlapped with the corresponding two vertical steel bars 232, and the overlap length can be determined according to actual conditions, but it needs to meet the design requirements. This embodiment does not impose any restrictions on this.

[0046] During specific implementation, the length of the vertical reinforcement 232 can be determined according to the actual buried depth, and this embodiment does not impose any limitation on this.

[0047] Preferably, each connecting rib 233 is integrally formed with the two vertical steel bars 232 connected thereto. Specifically, the two ends of one connecting rib 233 correspond one-to-one with the second ends of two vertical steel bars 232, and the connecting piece 233 is integrally formed with the two vertical steel bars 232 to form a U-shaped structure. The two ends of another connecting rib 233 correspond one-to-one with the second ends of the other two vertical steel bars 232, and the connecting piece 233 is integrally formed with the two vertical steel bars 232 to form a U-shaped structure.

[0048] The connection assembly may include: a connection plate 235, at least two embedded bolts 236 and at least two nuts 237. Part of each embedded bolt 236 is placed inside the reinforcement column 22, and the part of each embedded bolt 236 placed inside the reinforcement column 22 is connected to the corresponding connection rib 233. Another part of each embedded bolt 236 is placed outside the reinforcement column 22.

[0049] The connecting plate 235 is covered on the top of the reinforcing column 22, and the connecting plate 235 is provided with a through hole corresponding to each embedded bolt 236, the number of the through holes is the same as the number of the embedded bolts 236, each through hole corresponds to each embedded bolt 236, and the number of the embedded bolts 236 is the same as the number of the nuts 237, each embedded bolt 236 corresponds to each nut 237, and each embedded bolt 236 is penetrated in the corresponding through hole and is screwed with the corresponding nut 237. In this way, the reinforcing column 22 and the connecting plate 235 are connected by the embedded bolts 236 and the nuts 237, which facilitates the installation and removal of the connecting plate 235.

[0050] The connecting plate 235 is connected to the column 1. Preferably, the connecting plate 235 is connected to the column 1 by welding. The welding should be full and the weld quality should meet the design requirements.

[0051] When in use, the connecting plate 235 is first connected to the column 1. Then, the connecting plate 235 is connected to the reinforcement column 22 through the embedded bolts 236 and nuts 237.

[0052] In a specific implementation, the number of nuts 237 is twice the number of embedded bolts 236 , and each embedded bolt 236 is threadedly connected with two nuts 237 after being penetrated through the corresponding penetration hole.

[0053] When the top surface of the reinforcement column 22 is uneven, the top of the reinforcement column 22 is leveled by the grouting material 6, so that the top of the reinforcement column 22 remains flat. The grouting material 6 can be a high-strength non-shrinkage grouting material.

[0054] In this embodiment, each embedded bar 231 can be a Φ16 steel bar, and the depth of each embedded bar 231 placed in the structure 8 can be 150 mm, and the depth of each embedded bar 231 placed in the reinforcement column 22 can be 150 mm. Each vertical steel bar 232 can be a Φ16 steel bar. The diameter of each embedded bolt 236 is 20 mm and the length is 250 mm. The depth of each embedded bolt 236 placed in the reinforcement column 22 is at least 125 mm. Each stirrup 234 can be a Φ12 stirrup.

[0055] In this embodiment, the column 1 is a C-shaped steel column, and its specific parameters are 730mm C-shaped column 149×110 and a thickness of 4.3mm.

[0056] It can be seen that in this embodiment, when the foundation is a structure 8, the structure of the reinforcement mechanism 2 is simple and easy to implement, and the arrangement of each vertical steel bar 232 and each connecting rib 233 can improve the strength inside the reinforcement column 22, and each embedded rib 231 is connected to each vertical steel bar 232, which can ensure a stable connection between the reinforcement column 22 and the structure 8. After the column 1 is connected to the connecting plate 235, it is connected to the connecting rib 233 in the reinforcement column 22 through the connecting plate 235 and the embedded bolts 236, which can ensure a stable connection between the reinforcement column 22 and the column 1, effectively improving the stability and safety of the column 1. The connecting plate 235 is covered on the top of the reinforcement column 22 for easy maintenance in the later stage.

[0057] The construction steps of corrugated guardrail 3 are as follows:

[0058] 1. According to the roadbed design drawing, check the location of shallow roadbed sections, culverts or passages, and confirm the fill height above the top plate of the culvert or passage.

[0059] 2. Check the distribution of geological soil layers below the original ground through geological survey.

[0060] 3. The construction of column 1 is carried out after the roadbed base is filled.

[0061] When the foundation soil contains rock layers, the specific steps are:

[0062] (1) Based on the roadbed map, geological survey data and corrugated guardrail plan, a combination system of precast concrete columns + C-shaped steel columns is adopted;

[0063] (2) The side wall of the column 21 is serrated. When the column 21 is prefabricated, a steel formwork is used for support. A plurality of angle steels are welded on the inner side of the steel formwork. The width of each angle steel is not less than 5 cm. The angle steels are connected together in a folded arrangement so that the column 21 is serrated after pouring, which facilitates the column 21 to be firmly engaged with the soil when it contacts the soil after installation.

[0064] (3) The C-shaped steel column is located in the middle of the column 21. The cross-sectional size of the column 21 can be set to 350 mm × 350 mm. The height of the column 21 is not less than 0.6 m or is set according to the design requirements. Before pouring concrete into the steel formwork of the column 21, the C-shaped steel column 1 is inserted into the interior of the column 21, and then concrete is poured so that the column 21 and the C-shaped steel column 1 are connected as one.

[0065] (4) A hook is embedded in the top of the column 21, or a hook is set on the part of the C-shaped steel column 1 outside the column 21. The hook can be made of plain round steel bars with a diameter not less than D16. When the hook is set on the C-shaped steel column 1, the hook can be welded to the C-shaped steel column 1 and then bent to the outside of the C-shaped steel column 1. The exposed size of the hook at least meets the requirements of the insertion and fixing of the lifting bolts. The setting of the hook can facilitate the lifting of the column 21 and the C-shaped steel column 1 connected as a whole to the desired position through the hook.

[0066] After the column 21 and the C-shaped steel column 1 are prefabricated, the hooks should be cut off and then anti-corrosion paint should be applied externally.

[0067] (5) The concrete in the column 21 is C30 concrete. After the concrete pouring is completed, the curing period is in place and the strength meets the design strength, the column 21 and the C-shaped steel column 1 can be hoisted and transported to the site for installation. During hoisting, a crane or a car crane is used for installation, and the position is prevented from being offset, which will affect the later installation of the corrugated guardrail 3.

[0068] (6) After the prefabricated column 21 and the C-shaped steel column 1 are hoisted, the surrounding soil layer is backfilled and compacted layer by layer to ensure that the column 21 can be effectively connected with the soil layer to form a whole and maintain stability.

[0069] (7) The slope protection 5 on one side of the column 21 is constructed by planting grass or other slope protection methods.

[0070] When encountering a culvert / channel structure 8, where the fill thickness is less than the minimum buried depth of the column, the specific steps are as follows:

[0071] (1) The culvert / channel structure 8 is constructed first, and then the two sides of the structure 8 and the conical slope are symmetrically backfilled until the base is completed.

[0072] (2) According to the plan layout of the corrugated guardrail, confirm the location of the column 1 and dig the base soil to the top surface of the structure 8.

[0073] (3) Drill holes on the structure 8, the depth of the holes is not less than 15 cm, and there are four holes. Each hole is embedded with an embedded bar 231, and there are four embedded bars 231. Each embedded bar 231 is a threaded steel bar with a diameter not less than D16. The embedded length of each embedded bar 231 is not less than 15 cm, and the exposed length of each embedded bar 231 is not less than 15 cm. The four embedded bars 231 are arranged in a square shape. Four vertical steel bars 232 are connected to the four embedded bars 231 in a one-to-one correspondence, and each embedded steel bar is a D16 steel bar. A plurality of stirrups 234 are arranged at intervals along the height direction of the vertical steel bars 232, and each stirrup 234 is arranged outside each vertical steel bar 232, and each stirrup 234 is a threaded steel bar with a diameter not less than D12. One of the connecting bars 233 is transversely disposed at the second ends of the two vertical steel bars 232, and the other connecting bar 233 is transversely disposed at the second ends of the other two vertical steel bars 232. Each connecting bar 233 is a Φ12 U-shaped steel bar.

[0074] Chemical glue is injected into each drilled hole to enhance the connectivity between the embedded reinforcement 231 and the structure 8 .

[0075] (4) Embedded bolts 236 are provided on both connecting bars 233. A through hole is provided on the connecting plate 235 according to the position of each embedded bolt 236. When positioning the embedded bolt 236, the connecting plate 235 should be installed to confirm that the position of the embedded bolt 236 is correct. Then, an outer template is erected on the structure 8 and on the outer side of the vertical steel bar 232, and concrete is poured into the template, so that part of the embedded bar 231, each vertical steel bar 232, each connecting bar 233, each stirrup 234 and part of each embedded bolt 236 are poured inside the concrete. After the concrete curing is completed and the strength meets the design strength, the reinforcement column 22 can be formed. Part of each embedded bolt 236 is placed outside the reinforcement column 22.

[0076] (5) The concrete grade in the reinforcement column 22 is not less than C30, the cross-sectional dimensions of the reinforcement column 22 are 400 mm × 400 mm, the diameter of each embedded bolt 236 is not less than D16 mm, and the length of each embedded bolt 236 is not less than 250 mm. The length of each embedded bolt 236 placed in the reinforcement column 22 is not less than 125 mm.

[0077] (6) Before installing the column 1, check the flatness of the top of the reinforcement column 22. If it is not flat, use high-strength non-shrinkage grouting material 6 to level it. Connect the column 1 to the connecting plate 235 by welding. The welding is full and the weld quality meets the requirements.

[0078] (7) After the strength of the high-strength non-shrinkage grouting material 6 meets the requirements, install the column 1 and the connecting plate 235, insert the embedded bolts 236 into the penetration holes and screw them together with the nuts 237, so that the connecting plate 235 and the embedded bolts 236 are connected together.

[0079] (8) If the drawings of the structure, roadbed and corrugated guardrail can be completed at the same time, the column 1 can be directly constructed during the construction of the culvert / channel structure 8, and then the soil around the foundation can be backfilled to the shoulder elevation before installing the column 1.

[0080] (9) The slope protection 5 on one side of the reinforcement column 22 is constructed by planting grass or other slope protection methods.
