Description

Technical Field

[0001] The utility model relates to the technical field of road surface reinforcement, and more specifically to a device for reinforcing a short-distance road soft foundation. Background Art

[0002] In the field of road construction, especially in short-distance soft foundation reinforcement projects, it is crucial to ensure the stability of the road surface. When the soft soil foundation is subjected to road load, the soil is prone to lateral movement, which will cause serious damage to the road structure. In order to solve this problem, civil fences are widely used to reinforce the road surface on soft soil foundation.

[0003] The traditional reinforcement method is to lay multiple groups of civil fences on the roadbed, and the adjacent civil fences are overlapped at the edges. This edge overlap is just to simply overlap and place two civil fence bodies up and down at the edges. In practical applications, this prior art solution has a serious problem, that is, the connection between adjacent civil fences is not firm. Since vehicles driving on the road will generate static and dynamic loads, these loads will cause the road surface to bear repeated pressure and vibration. In this case, the traditional edge-overlapped civil fences are prone to produce small displacements between adjacent fences, and this displacement will gradually accumulate over time. The accumulation of this displacement will destroy the reinforcement effect of the civil fence on the soil, making it impossible to effectively restrain the lateral movement of the soil, thereby affecting the stability of the road base, and ultimately causing cracks, deformation and other damage to the road surface, reducing the service life and safety of the road.

[0004] Therefore, a device for reinforcing soft foundation of short-distance road surface is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a device for reinforcing soft foundation of a short-distance road surface to solve the existing problems in the above-mentioned background technology.

[0006] The utility model provides the following technical solutions: a device for reinforcing a soft foundation of a short-distance road surface, comprising a civil fence body, a roadbed layer laid at the bottom of the civil fence body, and an asphalt layer laid on the civil fence body, wherein the civil fence body is provided with a limiting net that is criss-crossed and distributed in a mesh shape, a row of connecting holes is provided on one side of the civil fence body, a row of mounting grooves is provided on the other side of the civil fence body, a connecting long rod that passes through all the mounting groove openings is provided on the same side as the mounting groove, a connecting component that is movably connected to the connecting long rod is provided inside each mounting groove, and a plurality of groups of connecting components are used to perform multi-point movably clamped connection with corresponding connecting holes of adjacent civil fence bodies.

[0007] Preferably, the connecting assembly includes a sleeve movably sleeved on the connecting long rod, and the outer side of the sleeve is sequentially connected with a connecting column and a connecting plug, and the connecting plug and the connecting column can be sequentially inserted into and penetrate the connecting holes on the sides of the adjacent civil fence bodies.

[0008] The diameter of the connecting plug is larger than the diameter of the connecting hole, and the connecting plug is made of soft elastic material.

[0009] Preferably, the sleeve can rotate 360 ​​degrees inside and outside the installation groove, and the sleeve can slide horizontally inside the opening of the corresponding installation groove.

[0010] Preferably, fixing nails are provided at the bottom of the civil fence body at the criss-cross nodes of the limiting net.

[0011] Preferably, the fixing nail includes a positioning rod and a first nail head connected to the bottom of the positioning rod.

[0012] Preferably, the fixing nails are arranged correspondingly at the top and bottom of the civil fence body, and the fixing nails also include a second nail head located at an end of the positioning rod away from the first nail head.

[0013] Technical effects and advantages of the utility model:

[0014] 1. The utility model realizes multi-point active connection between adjacent civil fence bodies by arranging connection holes, installation grooves, connecting long rods and connecting components on the civil fence body. This connection method overcomes the problem of unstable connection between adjacent civil fence bodies in the traditional edge overlap method, and greatly enhances the tightness of the connection between civil fences. During the use of the road, whether it is the static load or dynamic load of the vehicle, this connection method can effectively resist the stress generated, prevent relative displacement between the civil fence bodies, and make the entire civil fence system form a stable whole, so as to better play the lateral restraint and reinforcement role on the soft soil foundation and ensure the stability of the road base.

[0015] 2. The connection assembly of the utility model can rotate 360 ​​degrees inside and outside the installation groove, and the sleeve slides horizontally inside the opening of the corresponding installation groove. This design makes the civil fence have good adaptability during the laying process. In actual construction, complex conditions such as ground unevenness, slight changes in laying angles, undulating terrain or obstacles will not affect the construction. The connection assembly can automatically adjust its position to ensure the tightness of the connection, facilitate construction operations, reduce the difficulty of connection caused by unsatisfactory construction conditions, and improve construction efficiency and quality. This is a secondary effect.

[0016] 3. The utility model sets fixing nails at the bottom of the civil fence body at the crisscross nodes of the limit net, and sets them correspondingly at the top and bottom of the civil fence body. These fixing nails tightly connect the civil fence body with the roadbed and the asphalt layer, the first nail head is inserted into the roadbed, and the second nail head is connected to the asphalt layer. When subjected to external forces such as vehicle loads, the force can be better transmitted and dispersed in the entire structure, avoiding separation or relative sliding between layers, preventing stress concentration between layers, and further enhancing the stability and bearing capacity of the road structure.

[0025] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0026] See also Figure 1-Figure 7 In this embodiment, a device for reinforcing a short-distance soft foundation of a road surface includes a civil fence body 1, a road base layer 5 laid at the bottom of the civil fence body 1, and an asphalt layer 6 laid on the civil fence body 1. The road base layer 5 is located at the bottom of the civil fence body 1 and is an important basic part of the road structure. It provides support for the entire road surface. The asphalt layer 6 is laid on the civil fence body 1 and is the surface layer of the road that directly contacts the vehicle tires. It has good flatness and wear resistance and can provide comfortable road conditions for vehicle driving. At the same time, the asphalt layer 6 has a certain degree of flexibility and can adapt to the deformation of the road surface to a certain extent.

[0027] The civil fence body 1 is provided with a limiting net 101 which is crisscrossed and distributed in a mesh shape. A row of connecting holes 102 is provided on one side of the civil fence body 1, and a mounting groove 103 which is opposite to the connecting holes 102 on the adjacent civil fence body 1 is provided on the other side of the civil fence body 1. A connecting long rod 2 which passes through all the openings of the mounting grooves 103 is provided on the same side as the mounting grooves 103. A connecting component which is movably connected to the connecting long rod 2 is provided inside each mounting groove 103, and a plurality of groups of connecting components are used to perform multi-point movably clamped connection with the corresponding connecting holes 102 of the adjacent civil fence body 1.

[0028] Specifically, the connection hole 102 on one side of the civil fence body 1, the installation groove 103 on the other side, the connecting rod 2 that passes through the installation groove 103, and the connecting assembly on the connecting rod 2 (including the sleeve 3, the connecting column 301 and the connecting plug 302) cooperate with each other. When the traditional civil fence body 1 is laid, only the edges are overlapped, and the connection between adjacent civil fence bodies 1 is not fixed. However, this solution makes the connection between adjacent civil fence bodies 1 more secure through the multi-point active clamping of the connecting assembly and the connecting hole 102. This multi-point active clamping method can effectively resist the stress generated by factors such as vehicle load during road use, prevent relative displacement between civil fence bodies 1, ensure the stability of the entire civil fence body 1 structure, and thus better play the role of reinforcing the soil.

[0029] During the driving process, the road is subjected to repeated vibration and pressure. If the civil fence body 1 is not firm, it is easy to loosen, affecting the reinforcement effect of the soft soil foundation. The connection method in this embodiment can effectively avoid this situation, ensuring that the civil fence body 1 can still stably restrain the soil in long-term use.

[0030] In this embodiment, if Figure 2 and Figure 6As shown, the connection assembly includes a sleeve 3 movably sleeved on the connecting long rod 2, and the outer side of the sleeve 3 is sequentially connected with a connecting column 301 and a connecting plug 302, and the connecting plug 302 and the connecting column 301 can be sequentially inserted into and penetrate the connecting hole 102 on the side of the adjacent civil fence body 1. Among them, the cylindrical rod diameter of the connecting column 301 is the same as the inner diameter of the corresponding connecting hole 102, which facilitates the insertion of the connecting column 301 into the corresponding connecting hole 102, and the diameter of the connecting plug 302 is larger than the diameter of the connecting hole 102, and the connecting plug 302 is made of a soft elastic material, such as rubber. In the present technical solution, the connecting plug 302 at the other end of the connecting column 301 can be first squeezed and deformed to be inserted into the connecting hole 102, and then enter the hole of the limiting net 101 in the civil fence body 1. When the connecting plug 302 passes through the inside of the connecting hole 102, the corresponding connecting component is fixed to the corresponding civil fence body 1. Multiple groups of connecting components fix the civil fence body 1 and the adjacent ends of the civil fence body 1 at multiple points.

[0031] The connecting assembly can rotate 360 ​​degrees inside and outside the installation groove 103 , and the sleeve 3 can slide horizontally inside the opening of the corresponding installation groove 103 .

[0032] The above structure can make the civil fence more adaptable during the laying process. In actual construction, the ground may have certain unevenness or slight changes in the laying angle. The rotation and sliding ability of the connection component can make the civil fence body 1 automatically adjust its position during the connection process, better adapt to the site conditions, ensure the tightness of the connection, and also facilitate construction operations. In complex construction sites, there may be undulating terrain or obstacles. The characteristics of this connection component allow the civil fence body 1 to be flexibly adjusted within a certain range, reducing the connection difficulties caused by unsatisfactory construction conditions and improving construction efficiency and quality.

[0033] In this embodiment, fixing nails are provided at the criss-cross nodes of the limiting net 101 at the bottom of the civil fence body 1, and the fixing nails include a positioning rod 4 and a first nail head 401 connected to the bottom of the positioning rod 4. In order to further reinforce the road base layer 5 and the asphalt layer 6 between the upper and lower sides of the civil fence body 1, the fixing nails are correspondingly arranged at the top and bottom of the civil fence body 1, and the fixing nails also include a second nail head 402 located at the end of the positioning rod 4 away from the first nail head 401.

[0034] Specifically, the fixing nails tightly connect the civil fence body 1 with the upper and lower roadbed layers 5 and asphalt layers 6. The first nail head 401 is inserted into the roadbed layer 5, and the second nail head 402 also has a connecting function with the asphalt layer 6 at the top of the civil fence body 1, so that the civil fence forms a whole with the roadbed layer 5 and the asphalt layer 6. In this way, when subjected to external forces such as vehicle loads, the force can be better transmitted and dispersed in the entire structure to avoid separation or relative sliding between the layers. When the vehicle is driving on the road surface, the load is transmitted downward through the asphalt layer 6. If the connection between the layers is not good, stress concentration is likely to occur between the layers. The fixing nails in this embodiment ensure the coordinated work of the civil fence body 1 with the roadbed layer 5 and the asphalt layer 6, and improve the bearing capacity of the road structure.

[0035] The working principle and use process of the utility model: when in use, a connection hole 102 is provided on one side of the civil fence body 1 and a mounting groove 103 is provided on the other side of the civil fence body 1, and a connecting rod 2 and a connecting assembly movably connected to the corresponding connecting rod 2 are provided inside the mounting groove 103, and multiple groups of connecting assemblies are used to perform multi-point active clamping with the corresponding connecting holes 102 of the adjacent civil fence bodies 1. Furthermore, a multi-point active clamping scheme is used to fix the connecting ends of multiple groups of civil fence bodies 1, thereby strengthening the fixing effect between the multiple groups of civil fence bodies 1.

[0036] Specifically, during the construction process, the civil fence body 1 is first hoisted or transported to a predetermined position on the roadbed 5. Since each civil fence body 1 is provided with standard connection holes 102, installation slots 103 and other structures, construction workers can conveniently perform installation operations.

[0037] After the first civil fence body 1 is placed, a connection assembly is placed in each installation groove 103, and the connecting long rod 2 is passed through the installation groove 103 of the adjacent civil fence body 1. In this process, the connecting long rod 2 can pass smoothly, thanks to the matching degree between the design size of the installation groove 103 and the connecting long rod 2. The sleeve 3 can be flexibly sleeved on the connecting long rod 2, because there is a suitable gap between the inner diameter of the sleeve 3 and the outer diameter of the connecting long rod 2, allowing the sleeve 3 to move freely on the connecting long rod 2.

[0038] The connecting column 301 firmly connects the sleeve 3 and the connecting plug 302 to ensure effective force transmission. When the connecting plug 302 is inserted into the connecting hole 102 of the adjacent civil fence body 1, since the connecting component can rotate 360 ​​degrees inside and outside the installation groove 103, and the sleeve 3 slides horizontally inside the opening of the corresponding installation groove 103, during the insertion process, the connecting component can automatically adjust the angle and position according to the position of the connecting hole 102 to achieve smooth insertion. This multi-point active clamping method greatly enhances the connection tightness between adjacent civil fence bodies 1 compared to traditional edge overlap.

[0039] Moreover, in actual road use, both static and dynamic loads of vehicles will generate pressure and vibration on the road surface. For traditional edge-jointed civil fences, these loads can easily cause tiny displacements between adjacent civil fences. Over time, this displacement will gradually accumulate, destroying the reinforcement effect of the civil fence on the soil. In the present technical solution, the multi-point active card-jointed connection method can effectively resist the impact of these loads. The tight fit between the connecting hole 102 and the connecting assembly can limit the movement of the civil fence body 1 in all directions, so that the entire civil fence system forms a stable whole. When the load acts on the road surface, the stress is transmitted downward through the asphalt layer 6 and the civil fence body 1. Due to the firm connection between the civil fence body 1, the stress can be evenly dispersed throughout the entire reinforcement system, rather than concentrated in one place, so as to better restrain the lateral movement of the soil in the soft soil foundation and ensure the stability of the road base 5.

[0040] At the same time, the fixing nails at the crisscross nodes of the limiting net 101 at the bottom of the civil fence body 1 also play an important role. When installing the civil fence body 1, the first nail head 401 on the positioning rod 4 will extend into the road base layer 5, firmly fixing the civil fence body 1 on the road base layer 5. Moreover, the fixing nails arranged correspondingly at the top and bottom of the civil fence body 1, and the second nail heads 402 at the top also have a certain connection effect with the asphalt layer 6. Such fixing nails arranged correspondingly up and down make the connection between the civil fence body 1 and the road base layer 5 and the asphalt layer 6 tighter, forming an overall structure that works in coordination. During the load transfer process, the fixing nails ensure that there is no relative sliding between the layers, further enhancing the stability and bearing capacity of the road structure.
