[0028] Combination Figure 1-5 As shown, the embodiment of the present disclosure provides a roadbed anti-sinking device for road construction, which is arranged below the roadbed 3 and includes: an anti-sinking plate 4, a support tube 5 and a connecting rod 13. The anti-sinking plate 4 is arranged below the roadbed 3, and a plurality of first support plates 9 and second support plates 11 are arranged between the anti-sinking plate 4 and the roadbed 3, and a filling layer 17 is arranged between the first support plate 9 and the second support plate 11; the support tube 5 and the first support plate 9 and the second support plate 11 are arranged to intersect with each other, the first support plate 9 is fixedly connected to the upper position of the support tube 5, the second support plate 11 is fixedly connected to the lower position of the support tube 5, and the top surface of the support tube 5 is penetrated by a water-permeable opening 10, and the side wall is penetrated by a water-permeable hole 6, and one end of the water-permeable hole 6 extends into the water-permeable opening 10; the connecting rod 13 is detachably arranged between two adjacent second support plates 11, and the two ends of the connecting rod 13 are movably connected to the side walls of the two second support plates 11 respectively.
[0029] By using the roadbed anti-sinking device for road construction provided by the embodiment of the present disclosure, when passing vehicles pass through the road surface, multiple first support plates 9 can provide buffer support at multiple positions on the lower side of the roadbed 3, and the filling layer 17 can buffer the pressure transmitted by the multiple first support plates 9 between the first support plate 9 and the second support plate 11, and the multiple second support plates 11 are connected to each other by connecting rods 13, so that the multiple second support plates 11 can form an integral support structure on the lower side of the filling layer 17, which can increase the contact area with the anti-sinking plate 4, so that the multiple second support plates 11 and the anti-sinking plate 4 can cooperate with each other to provide support for the road surface, improve the load-bearing strength of the road surface, and avoid road surface collapse; and in rainy weather, after rainwater penetrates into the second support plate 11, it can enter the support tube 5 through the water permeable port 10, and then flow out to the surroundings through the water permeable holes 6 on the support tube 5, which is conducive to timely discharge of rainwater, and avoids rainwater accumulation on the lower side of the roadbed 3 causing road surface collapse.
[0030] It is worth noting that the anti-sinking plate 4 can be a rectangular plate integrally formed by casting reinforced concrete, or can be formed by splicing a plurality of reinforced concrete cast prefabricated plates.
[0031] Optionally, the filling layer 17 is formed by mixing and stirring materials such as sandstone, quicklime, construction waste residue, cement, etc. In this way, the filling material is simple and easy to take, easy to collect and use, and construction waste residue can also be used for filling, which is beneficial to environmental protection and energy saving.
[0032] It can be understood that when paving the road, after the filling layer 17 is laid, water can be sprayed into the filling layer 17 to allow the quicklime to fully react and calcify, and then it can be compacted using a roller, and finally the roadbed 3 and concrete cushion layer 2 can be laid, which is beneficial to reduce the gaps in the filling layer 17 and improve the supporting strength of the filling layer 17.
[0033] Optionally, an asphalt pavement 1 is laid directly above the roadbed 3, and a concrete cushion layer 2 is laid between the roadbed 3 and the asphalt pavement 1. In this way, by laying the concrete cushion layer 2 on the upper side of the roadbed 3, a protective structure can be formed on the upper side of the roadbed 3, thereby improving the load-bearing strength of the roadbed 3 and preventing the roadbed 3 from breaking or collapsing.
[0034] It can be understood that the thickness of the concrete cushion layer 2 and the concrete strength can be selected according to the actual construction environment and road construction requirements.
[0035] Optionally, the first support plate 9 and the second support plate 11 have the same size. In this way, the passing vehicles on the asphalt pavement 1 can be better supported, and the load transmitted by the asphalt pavement 1 can be better buffered by the first support plate 9 and the second support plate 11, thereby improving the supporting performance of the first support plate 9 and the second support plate 11.
[0036] Optionally, the first support plate 9 and the second support plate 11 are both cast in reinforced concrete. In this way, the support strength of the first support plate 9 and the second support plate 11 can be ensured, and the first support plate 9 and the second support plate 11 can have good water permeability; and the first support plate 9 and the second support plate 11 can be prefabricated in advance, which is conducive to improving the subsequent laying efficiency.
[0037] In order to more conveniently install and fix the support tube 5, optionally, a mounting hole is provided through the center of the top end surface of the first support plate 9 and the second support plate 11, and the mounting hole is adapted to the support tube 5. In this way, it is convenient to insert and install the support tube 5 in the first support plate 9 and the second support plate 11 through the mounting holes on the first support plate 9 and the second support plate 11.
[0038] It can be understood that the anti-sinking plate 4 is evenly provided with a plurality of mounting holes, so that after the support tube 5 is inserted and installed in the first support plate 9 and the second support plate 11, the bottom end of the support tube 5 can pass through the mounting holes on the anti-sinking plate 4 and be inserted into the hard soil.
[0039] Optionally, the top surface of the first support plate 9 contacts the bottom surface of the roadbed 3, and the bottom surface of the second support plate 11 contacts the top surface of the anti-sinking plate 4. In this way, the roadbed 3, the first support plate 9, the second support plate 11 and the anti-sinking plate 4 can form an integral support structure, thereby buffering the pressure transmitted on the asphalt pavement 1, which is beneficial to improving the load-bearing strength and preventing the asphalt pavement 1 or the roadbed 3 from being broken or collapsed.
[0040] Optionally, a plurality of water-permeable holes 6 are provided and arranged in an array on the side wall of the support tube 5. In this way, rainwater entering the support tube 5 can be discharged through the plurality of water-permeable holes 6, so that the rainwater penetrates into the filling layer 17 and flows underground, which is helpful to prevent rainwater from accumulating under the roadbed 3 and causing the roadbed 3 to collapse, thereby improving the supporting strength of the roadbed 3.
[0041] Optionally, a conical head 7 is fixedly connected to the bottom end surface of the support tube 5, and a plurality of convex thorns 8 are fixedly connected to the side wall of the support tube 5. In this way, the conical head 7 facilitates the bottom end of the support tube 5 to be inserted into the underground hard soil, which can improve the support stability of the support tube 5; at the same time, under the weight of the filling layer 17 and the passing vehicles on the roadbed 3 and the road surface, the plurality of second support plates 11 will be pressed downward, so that the bottom end surface of the second support plate 11 abuts against the plurality of convex thorns 8, which is conducive to improving the support stability of the support tube 5 and preventing the support tube 5 from tilting.
[0042] In order to further improve the drainage effect of the support tube 5 and prevent rainwater from gathering in the support tube 5, the conical head 7 is optionally connected to the inside of the support tube 5. In this way, when the amount of rainwater entering the support tube 5 is small, the rainwater can directly pass through the conical head 7 and enter the ground; when the amount of rainwater is large and gathers in the support tube 5, part of the rainwater can penetrate into the filling layer 17 through the water-permeable holes 6, and the other part of the rainwater can pass through the conical head 7 and enter the ground, thereby preventing rainwater from gathering in the support tube 5 and improving the drainage effect.
[0043] In order to better improve the installation stability of the support tube 5, optionally, a plurality of convex thorns 8 are arranged in a triangular shape on the side wall of the support tube 5, and the plurality of convex thorns 8 are arranged upwardly tilted. In this way, when the second support plate 11 is pressed downward, the plurality of convex thorns 8 arranged upwardly tilted can better abut against the bottom end surface of the second support plate 11, thereby facilitating the improvement of the stability of the support tube 5, and making the support tube 5 better vertically fixed in the second support plate 11, so that when rainwater on the asphalt pavement 1 penetrates into the roadbed 3, it enters the support tube 5 through the water permeable port 10, and then is discharged through the plurality of water permeable holes 6 and extends into the ground.
[0044] In order to better make the thorn 8 abut against the bottom end surface of the second support plate 11, thereby improving the installation stability of the support tube 5, optionally, the end surface of the thorn 8 facing the second support plate 11 is parallel to the bottom end surface of the second support plate 11. In this way, the upward end surface of the thorn 8 is easy to abut against the bottom end surface of the second support plate 11, avoiding the end of the thorn 8 from causing damage to the second support plate 11.
[0045] In order to more conveniently connect and fix the plurality of second support plates 11, optionally, fixing holes 12 are provided on the opposite side walls of two adjacent second support plates 11, and the two ends of the connecting rod 13 are movably connected to the fixing holes 12. In this way, the two ends of the connecting rod 13 can be inserted into the two opposite side walls of the two adjacent second support plates 11, thereby realizing the movable connection of the two adjacent second support plates 11, facilitating the connection of the plurality of second support plates 11 into one piece, thereby facilitating the increase of the supporting area of the plurality of second support plates 11 and the increase of the load bearing strength.
[0046] In order to better adjust the connection length between the two connection rods 13, optionally, the connection rods 13 are arranged in pairs, and the two connection rods 13 are movably connected through a rotating connection mechanism, and the rotating connection mechanism can adjust the connection length between the two connection rods 13. In this way, after the two adjacent second support plates 11 are connected through the two connection rods 13, the connection length between the two connection rods 13 can be further adjusted through the rotating connection mechanism, thereby adjusting the connection length between the two adjacent second support plates 11, which is conducive to adjusting the connection length between the multiple second support plates 11 according to the actual laying needs, thereby improving the support area and support stability of the multiple second support plates 11.
[0047] In order to better improve the installation efficiency between the connecting rod 13 and the second support plate 11, optionally, one end of the connecting rod 13 connected to the fixing hole 12 is made of elastic material, and the diameter of the end of the connecting rod 13 connected to the fixing hole 12 is larger than the hole diameter of the fixing hole 12. In this way, it is convenient to directly squeeze the end of the connecting rod 13 into the fixing hole 12, which is conducive to improving the installation efficiency.
[0048] In order to better adjust the connection length between two adjacent second support plates 11 so that they are located at different support positions and improve the support performance, the rotary connection mechanism optionally includes: a threaded hole 14, a knob 15 and a screw 16. The threaded hole 14 is set on the opposite end surfaces of the two connecting rods 13; the knob 15 is set between the two connecting rods 13; the screw 16 is fixedly connected to the two ends of the knob 15, and the screw 16 is adapted to the threaded hole 14. In this way, when multiple second support plates 11 are connected to each other through the connecting rod 13, the two connecting rods 13 can be controlled to move relative to each other by rotating the knob 15, thereby increasing the connection length between the two second support plates 11, which is conducive to adjusting the support positions of the multiple second support plates 11, thereby increasing the contact area between the support surface formed after the multiple second support plates 11 are connected and fixed by the connecting rod 13 and the anti-sinking plate 4, which is conducive to improving the support performance.
[0049] In order to better protect the connecting rod 13 so that it can better provide connection support for the second support plate 11, optionally, the two connecting rods 13 and the knob 15 have the same diameter, and a rubber sheath is provided on the outer wall thereof. In this way, the connection between the knob 15 and the two connecting rods 13 can be protected by the rubber sheath to prevent erosion by rainwater, thereby facilitating the two connecting rods 13 to provide connection support between the two second support plates 11.
[0050] In order to better improve the supporting performance of the plurality of second supporting plates 11, optionally, the second supporting plates 11 are provided with fixing holes 12 in pairs on the four circumferential side walls thereof. In this way, the plurality of second supporting plates 11 can be installed and fixed on the anti-sinking plate 4 through the cooperation between the connecting rod 13 and the rotating connecting mechanism, which is conducive to further forming the plurality of second supporting plates 11 into a whole, increasing the contact area between the anti-sinking plate 4, and further improving the supporting performance.
