[0002] The bored pile technology process is mature and widely used in pile foundation projects such as various bridges and buildings. However, the waste slurry generated during its use has the disadvantages of large output, difficult to handle, and high pollution.

[0003] Using waste slurry to recharge karst caves is an effective treatment method. However, when encountering large karst caves, the slurry is difficult to meet the actual usage. Therefore, an anti-overflow net device for recharging old slurry into karst caves is needed, which can not only control the volume of the slurry but also make it have sufficient bearing capacity.

[0004] In view of this, the technical solution proposes an anti-overflow net device for recharging old slurry into karst caves, which is convenient to better solve the above-mentioned problems. Content of the Utility Model

[0005] The technical solution adopted by the utility model is as follows: An anti-overflow net device for recharging old slurry into karst caves, including a foundation. Above the interior of the foundation, a grouting port and an outer anti-overflow port communicated with the karst cave are provided. Through the grouting pipe in the outer anti-overflow port, the outer anti-overflow net, the middle anti-overflow net, and the inner anti-overflow net are pushed into the grouting port and then into the interior of the karst cave through the grouting port for placement.

[0006] The slurry is injected into the interior of the inner anti-overflow net through the grouting pipe and comes into contact and fusion with the middle anti-overflow net and the outer anti-overflow net. At this time, with the cooperation of the outer anti-overflow net, the middle anti-overflow net, and the inner anti-overflow net, anti-overflow protection is provided for the slurry. The slurry is poured into the interior of the grouting port and the outer anti-overflow port. Below the slurry in the outer anti-overflow port, a lower protection net, a middle protection net, and an upper protection net are sequentially placed, and the slurry continues to be poured and fused with the lower protection net, the middle protection net, and the upper protection net.

[0007] In a preferred embodiment, the grouting port and the outer anti-overflow port are of a stepped structure, so that the outer anti-overflow net, the middle anti-overflow net, and the inner anti-overflow net can be better limited in the karst cave.

[0008] In a preferred embodiment, the mesh specifications of the outer anti-overflow net, the middle anti-overflow net, and the inner anti-overflow net are different, and the mesh specification of the outer anti-overflow net is smaller than that of the middle anti-overflow net, and the mesh specification of the middle anti-overflow net is larger than that of the inner anti-overflow net.

[0009] In a preferred embodiment, mounting seats are fixed at the inner center positions of the outer anti-overflow net, the middle anti-overflow net, and the inner anti-overflow net. A positioning groove is formed above the inner part of the mounting seat, and a positioning column matching with the positioning groove is fixed at the bottom of the mounting seat. Through the cooperation of the positioning groove and the positioning column, the outer anti-overflow net, the middle anti-overflow net, and the inner anti-overflow net can be limited together for one-time installation.

[0010] In a preferred embodiment, the outer anti-overflow net, the middle anti-overflow net, and the inner anti-overflow net are all elastic nets.

[0011] In a preferred embodiment, the outer anti-overflow net, the middle anti-overflow net, and the inner anti-overflow net can be installed in staggered positions to better achieve the effect of preventing the overflow of mud.

[0012] In a preferred embodiment, the mesh specifications of the lower protective net, the middle protective net, and the upper protective net gradually become smaller from bottom to top, and the lower protective net, the middle protective net, and the upper protective net are placed separately by mud.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows: The outer anti-overflow net, the middle anti-overflow net, and the inner anti-overflow net can effectively reduce the amount of mud used, and can effectively prevent the mud from flowing out through the outer anti-overflow net, the middle anti-overflow net, and the inner anti-overflow net, so that the outer anti-overflow net, the middle anti-overflow net, and the inner anti-overflow net can effectively control the volume of the mud and have sufficient bearing capacity. Moreover, it is more convenient to operate inside the karst cave with the outer anti-overflow net, the middle anti-overflow net, and the inner anti-overflow net. At the same time, the lower protective net, the middle protective net, and the upper protective net can effectively reduce the amount of mud used, and can separately protect the mud inside the outer anti-overflow port and can play a certain anti-overflow effect.

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0020] The following will be combined with Figures 1-4 to give a detailed description of an anti - overflow net device for an old mud back - filling karst cave.

[0021] Refer to Figures 1-3 As shown, an anti - overflow net device for an old mud back - filling karst cave includes a foundation 1. Above the interior of the foundation 1, a grouting port 3 and an outer anti - overflow port 4 that are communicated with the karst cave 2 are provided. Inside the outer anti - overflow port 4, the outer anti - overflow net 5, the middle anti - overflow net 6, and the inner anti - overflow net 7 are pushed into the grouting port 3 through a grouting pipe 11, and the outer anti - overflow net 5, the middle anti - overflow net 6, and the inner anti - overflow net 7 are pushed into the interior of the karst cave 2 through the grouting port 3 for placement. The grouting port 3 and the outer anti - overflow port 4 are of a stepped structure, so that the outer anti - overflow net 5, the middle anti - overflow net 6, and the inner anti - overflow net 7 can be better limited in the karst cave 2. The mesh specifications of the outer anti - overflow net 5, the middle anti - overflow net 6, and the inner anti - overflow net 7 are different, and the mesh specification of the outer anti - overflow net 5 is smaller than that of the middle anti - overflow net 6, and the mesh specification of the middle anti - overflow net 6 is larger than that of the inner anti - overflow net 7. The outer anti - overflow net 5, the middle anti - overflow net 6, and the inner anti - overflow net 7 are all elastic nets.

[0022] Refer to Figures 3-4 As shown, at the central positions inside the outer anti - overflow net 5, the middle anti - overflow net 6, and the inner anti - overflow net 7, mounting seats 8 are fixedly provided. Above the interior of the mounting seats 8, positioning grooves 9 are provided. At the bottom of the mounting seats 8, positioning posts 10 corresponding to the positioning grooves 9 are fixedly provided. Through the cooperation of the positioning grooves 9 and the positioning posts 10, the outer anti - overflow net 5, the middle anti - overflow net 6, and the inner anti - overflow net 7 can be limited together for one - time installation. The installation parts of the positioning grooves 9 and the positioning posts 10 are both of a regular hexagon structure.

[0023] Refer to Figures 1-2As shown, the slurry 12 is injected into the interior of the inner anti-overflow net 7 through the grouting pipe 11 and comes into contact and fusion with the middle anti-overflow net 6 and the outer anti-overflow net 5. At this time, with the cooperation of the outer anti-overflow net 5, the middle anti-overflow net 6 and the inner anti-overflow net 7, anti-overflow protection is provided for the slurry 12. The slurry 12 is poured into the interior of the grouting port 3 and the outer anti-overflow port 4. The outer anti-overflow net 5, the middle anti-overflow net 6 and the inner anti-overflow net 7 can be installed at staggered positions to better achieve the anti-overflow effect on the slurry 12. Inside the outer anti-overflow port 4 and above the slurry 12, a lower protective net 13, a middle protective net 14 and an upper protective net 15 are successively placed. And the slurry 12 continues to pour and fuse with the lower protective net 13, the middle protective net 14 and the upper protective net 15. The mesh specifications of the lower protective net 13, the middle protective net 14 and the upper protective net 15 gradually become smaller from bottom to top, and the lower protective net 13, the middle protective net 14 and the upper protective net 15 are separated and placed by the slurry 12.

[0024] Advantages of this application: Through the outer anti-overflow net 5, the middle anti-overflow net 6 and the inner anti-overflow net 7, the amount of slurry can be effectively reduced, and through the outer anti-overflow net 5, the middle anti-overflow net 6 and the inner anti-overflow net 7, the outflow of the slurry can be effectively prevented, enabling the outer anti-overflow net 5, the middle anti-overflow net 6 and the inner anti-overflow net 7 to effectively control the volume of the slurry and endow it with sufficient bearing capacity. Moreover, when operating inside the karst cave 2 with the outer anti-overflow net 5, the middle anti-overflow net 6 and the inner anti-overflow net 7, it is more convenient. At the same time, through the lower protective net 13, the middle protective net 14 and the upper protective net 15, the amount of slurry can be effectively reduced, and the slurry 12 inside the outer anti-overflow port 4 can be separated and protected, and a certain anti-overflow effect can be achieved.

[0025] Working principle: The outer anti-overflow net 5, the middle anti-overflow net 6 and the inner anti-overflow net 7 are installed staggeredly together through the cooperation of the positioning groove 9 and the positioning post 10. Then, the outer anti-overflow net 5, the middle anti-overflow net 6 and the inner anti-overflow net 7 are placed above the outer anti-overflow port 4, so that the mounting seat 8 is located inside the outer anti-overflow port 4 and opposite to the grouting port 3. Then, by abutting the grouting pipe 11 against the mounting seat 8, the outer anti-overflow net 5, the middle anti-overflow net 6 and the inner anti-overflow net 7 can be pushed into the inside of the karst cave 2 through the grouting port 3 for placement. At the same time, the mud 12 is injected into the inside of the karst cave 2 through the grouting pipe 11 and contacts the outer anti-overflow net 5, the middle anti-overflow net 6 and the inner anti-overflow net 7, which can effectively reduce the consumption of the mud and can play a certain anti-overflow effect. After the grouting inside the karst cave 2 is completed, the grouting pipe 11 is moved upward. At this time, the inside of the grouting port 3 and the outer anti-overflow port 4 can be grouted. When the grouting inside the outer anti-overflow port 4 reaches a certain height, the lower protective net 13, the middle protective net 14 and the upper protective net 15 are sequentially placed inside the outer anti-overflow port 4 and separated by the mud 12 and fused with the mud 12, which can effectively reduce the consumption of the mud, and can separate and protect the mud 12 inside the outer anti-overflow port 4 and can play a certain anti-overflow effect.

[0026] The above embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
