Description

Technical Field

[0001] This utility model relates to the field of roadbed settlement prevention technology, specifically to a layered compacted embankment roadbed settlement prevention structure. Background Technology

[0002] Embankment subgrade refers to the subgrade structure formed by artificially filling materials such as soil and rock during road construction. Its core principle is to ensure sufficient strength, stability, and durability of the subgrade through the rational selection of fill materials and control of the filling process. It generally employs layered filling followed by compaction. Settlement is one of the most common subgrade defects, primarily caused by adverse geological conditions, changes in groundwater levels, traffic loads, and aging of subgrade materials.

[0003] Because vehicles travel within the traffic markings on the road via their wheels, the local area where the road contacts the vehicle wheels bears greater stress. When the road is used for a long time or the vehicle is overloaded, the stress in this area is greater than that in other areas of the road, which can easily lead to roadbed settlement.

[0004] Current anti-settlement roadbed structures primarily target settlement caused by water erosion, mainly by increasing the traffic flow in the anti-settlement layer. However, there are still structural layers such as sand and gravel layers above the anti-settlement layer, which cannot effectively solve the problem of roadbed settlement caused by traffic loads. Utility Model Content

[0005] The purpose of this invention is to provide a layered compaction embankment subgrade anti-settlement structure to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A layered compacted fill subgrade anti-settlement structure includes a subgrade body and an anti-settlement component installed on the subgrade body. The anti-settlement component includes multiple vertically installed fixing rods, which are fixedly connected to the subgrade body. Multiple horizontal bearing plates are connected to the fixing rods. The structure also includes a connector for fixing the fixing rods.

[0008] Furthermore, a protrusion is provided on the fixing rod along the axial direction, and a groove adapted to the protrusion is provided on the bearing plate, wherein the protrusion and the groove are adapted to each other.

[0009] Furthermore, the protrusion is provided with multiple locking grooves, the depth of which is adapted to the thickness of the pressure plate.

[0010] Furthermore, multiple side plates are fixedly installed on the pressure plate, and the two ends of the side plates are respectively fixedly connected to the adjacent side plates to form a fixing groove.

[0011] Furthermore, the end of the fixing rod is pointed.

[0012] Furthermore, the connector includes a plurality of first connecting rods, each first connecting rod being slidably connected to two adjacent fixed rods, and two second connecting rods being detachably connected between adjacent first connecting rods.

[0013] In the above technical solution, the beneficial effects of the layered compaction embankment anti-settlement structure provided by this utility model are as follows:

[0014] 1. Through the installation of anti-settlement components, multiple support plates can disperse the stress on the roadbed when vehicles are driving on the road, thereby increasing the stress range of the roadbed, reducing the local pressure of vehicles on the roadbed, and extending the service life of the road.

[0015] 2. The connectors fix each fixing rod, ensuring that the fixing rods always maintain a relative distance and are always vertical, allowing the pressure plate to disperse the force. On the other hand, the connectors allow each fixing rod to transmit the force to other fixing rods and the pressure plate, further dispersing the force and ensuring that the fixing rods and the pressure plate can function stably.

[0016] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0026] Please see Figure 1-4 A layered compacted fill roadbed anti-settlement structure includes a roadbed body 1 and an anti-settlement component 2 disposed on the roadbed body 1. The anti-settlement component 2 includes a plurality of vertically arranged fixing rods 21, which are fixedly connected to the roadbed body 1. A plurality of horizontal bearing plates 22 are connected to the fixing rods 21. The structure also includes a connector 3 for fixingly connecting each fixing rod 21.

[0027] Generally, the roadbed 1 consists of multiple structural layers from bottom to top, including a subgrade, a base course, and a surface course. These layers are laid and compacted according to national standards, a technique commonly used by those skilled in the art and will not be elaborated further. The bearing plates 22 can be installed within the roadbed 1 (except for the surface course) to distribute stress.

[0028] Furthermore, the fixing rod 21 is provided with a protrusion 23 along the axial direction, and the pressure plate 22 is provided with a groove 24 that matches the protrusion 23. The protrusion 23 and the groove 24 are adapted to each other. The pressure plate 22 can be slidably connected to the fixing rod 21 through the groove 24 for easy installation.

[0029] Furthermore, the protrusion 23 is provided with multiple locking grooves 25, the depth of which is adapted to the thickness of the pressure plate 22. When the pressure plate 22 slides into the locking groove 25, rotating the pressure plate 22 causes the groove 24 to no longer align with the protrusion 23, thereby locking the pressure plate 22 in the locking groove 25. Multiple locking grooves 25 make it easier to select the installation position of the pressure plate 22, avoiding the pressure plate 22 being placed at the boundary of the structural layers on the roadbed 1, which would affect the quality of the roadbed 1.

[0030] Furthermore, a plurality of side plates 26 are fixedly provided on the pressure plate 22, and the two ends of the side plates 26 are respectively fixedly connected to the adjacent side plates 26 to form a fixing groove 27. The fixing groove 27 is used to restrict the horizontal movement of materials within the structural layer to prevent the roadbed body 1 from settling; and the side plates 26 on the adjacent pressure plate 22 can also restrict the horizontal movement of materials.

[0031] Furthermore, the end of the fixing rod 21 is pointed. The pointed end of the fixing rod 21 is inserted into the roadbed body 1 to fix the fixing rod 21.

[0032] Furthermore, the connector 3 includes a plurality of first connecting rods 31, each first connecting rod 31 being slidably connected to two adjacent fixed rods 21. Two second connecting rods 32 are detachably connected between adjacent first connecting rods 31. The detachable connection is a bolted connection. The number of connectors 3 can be two, respectively disposed at the top and bottom of the fixed rods 21, achieving separate fixation at the upper and lower ends, further restricting the movement of the fixed rods 21 to ensure their stability and to transmit force.

[0033] Working principle: First, lay and compact the road base body 1 in layers, insert the fixing rod 21 into the road base body 1, and then install the connector 3 (at this time, the connector 3 is located on the upper side of the road base body 1). Continue to lay and compact the road base body 1 in layers, and install the bearing plate 22. Repeat the above process until the road base body 1 is laid.

[0034] When a vehicle travels over the top of the roadbed 1, the roadbed 1 will transmit the force to the pressure plate 22, expanding the force range of the roadbed 1. On the other hand, the fixed rod 21 transmits the force to the adjacent fixed rod 21 and the pressure plate 22 through the connector 3, ensuring the stability of the fixed rod 21.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
