Description

Technical Field

[0001] This utility model relates to the technical field of foundation pit support devices, specifically to a foundation pit anchor support structure under pipeline rupture conditions. Background Technology

[0002] In actual foundation pit structures, rock bursts are often present, which may lead to roof accidents, damage to the foundation pit structure, casualties, equipment damage, pollution of the working environment, and impact on production. Effective support measures for the working face can greatly reduce the occurrence of rock burst damage to the foundation pit structure. Anchor bolt support is a common support measure.

[0003] A search revealed a patent document with publication number CN221421926U that discloses an anti-buoyancy anchor rod. This utility model discloses an anti-buoyancy anchor rod comprising a rod body and external threads on the outer wall of the rod body. Multiple positioning elements are fitted onto the rod body, each positioning element including a mating part and two limiting feet on the mating part. The limiting feet are inclined and mirror-symmetrically positioned on both sides of the mating part. The mating part has mating holes. The positioning elements are fixed to the rod body, with the limiting feet positioned above the mating part. A crisscrossing steel mesh is provided at the top of the rod body, and the steel mesh is fixed to the rod body by hexagonal nuts. This utility model's anti-buoyancy anchor rod, by setting positioning elements on the rod body, forming a barbed structure similar to a fishhook, provides a more secure fit between the concrete and the positioning elements, preventing axial loosening of the rod body. The multiple steel meshes at the top of the rod body further strengthen the anchor rod's fixation. The threaded fit between the positioning elements and the rod body facilitates assembly.

[0004] The above-mentioned technical solutions rely solely on their own strength to resist the impact pressure during use, and cannot dissipate or release the pressure. When the impact pressure is large enough after the pipeline ruptures, traditional support measures often suffer rigid failure, which is insufficient for reinforcing the foundation pit structure.

[0005] Therefore, it is necessary to invent a foundation pit anchor support structure for pipeline rupture to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a foundation pit anchor support structure for pipeline rupture. By cooperating with the main anchor and the reinforcement mechanism, the stability of the structure is improved, thereby solving the problem that in the prior art, when the impact pressure after pipeline rupture is large enough, traditional support measures often suffer rigid failure and the reinforcement of the foundation pit structure is insufficient.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a foundation pit anchor support structure under pipeline rupture conditions, comprising a main anchor, with secondary anchors on both sides of the main anchor, and a reinforcement mechanism below the main anchor. The reinforcement mechanism includes a main connecting platform threaded to the bottom end of the main anchor, secondary connecting platforms on both sides of the main connecting platform, the secondary connecting platforms being threaded to the bottom end of the secondary anchors, and a bottom reinforcement platform fixedly connected to the bottom end of the secondary connecting platforms. The surface of the bottom reinforcement platform has two sets of bolt holes. A reinforcement mounting block is provided on the side of the bottom reinforcement platform near the main connecting platform. An internal groove is provided at the bottom end of the reinforcement mounting block, and a wrapping plate is fixedly connected to the bottom end of the reinforcement mounting block. Bolt holes are provided inside both the wrapping plate and the internal groove. The cooperation of the internal groove and the wrapping plate enables the splicing of the bottom reinforcement platform and the reinforcement mounting block, so that the main anchor and secondary anchors are radially distributed.

[0008] Preferably, the width of the bottom reinforcing platform is the same as the width of the internal groove, and the positions of bolt hole one and bolt hole two correspond to each other, so that bolt connection is achieved by the cooperation of bolt hole one and bolt hole two.

[0009] Preferably, two sets of plug-in blocks are fixedly connected to both sides of the main connecting platform. Two sets of snap-fit ​​grooves are opened on the surface of the plug-in blocks to increase the contact area between the plug-in blocks and subsequent parts.

[0010] Preferably, the auxiliary connecting platform has two sets of fixing slots on the side near the main connecting platform. The bottom wall of the fixing slot is fixedly connected to two sets of snap-fit ​​blocks, and the size of the snap-fit ​​blocks is the same as that of the snap-fit ​​slot. The fixing slots are used to snap and limit the insertion blocks.

[0011] Preferably, the surfaces of the main anchor and the secondary anchor are threaded with two sets of V-shaped blocks, and the bottom of the V-shaped blocks are provided with several sets of deepening grooves. The cooperation between the V-shaped blocks and the deepening grooves increases the contact area with the soil and prevents them from rising or loosening due to buoyancy.

[0012] Preferably, a mesh pad is laid at the top of both the main anchor rod and the main anchor rod. A mesh bolt is provided at the top of the mesh pad and the mesh bolt is threadedly connected to the top of the main anchor rod. The mesh pad is fixed to the top of the main anchor rod by the mesh bolt, thereby improving stability.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] By cooperating with the main anchor rod and the reinforcement mechanism, the plug-in block and the fixing groove are engaged to interlock. The interlocking block and the interlocking groove inside the fixing groove are also engaged to interlock, thus achieving the initial connection between the main connecting platform and the secondary connecting platform. The splicing is further strengthened by the cooperation between the bottom reinforcement platform and the internal groove. The bottom reinforcement platform is limited by the cooperation between the wrapping plate and the bottom reinforcement platform, and the overall strength of the structure is strengthened by the cooperation between bolt hole two and bolt hole one. Thus, the main anchor rod and the secondary anchor rod are assembled in a radial pattern, thereby improving the stability of the structure. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-5The diagram illustrates a foundation pit anchor support structure for a pipeline rupture condition, comprising a main anchor 1, with secondary anchors 101 on both sides of the main anchor 1, and a reinforcement mechanism 2 below the main anchor 1. The reinforcement mechanism 2 includes a main connecting platform 201 threadedly connected to the bottom end of the main anchor 1, and secondary connecting platforms 202 on both sides of the main connecting platform 201. The secondary connecting platforms 202 are threadedly connected to the bottom ends of the secondary anchors 101, and a bottom reinforcement platform 204 is fixedly connected to the bottom end of the secondary connecting platforms 202. Two sets of bolt holes 205 are provided on the surface of the bottom reinforcement platform 204. A reinforcement mechanism 204 is located on the side of the bottom reinforcement platform 204 closest to the main connecting platform 201. A reinforcing mounting block 203 has an internal groove 206 at its bottom end. A wrapping plate 207 is fixedly connected to the bottom end of the reinforcing mounting block 203. Bolt holes 208 are opened inside both the wrapping plate 207 and the internal groove 206. The cooperation between the internal groove 206 and the wrapping plate 207 enables the splicing of the bottom reinforcing platform 204 and the reinforcing mounting block 203, so that the main anchor rod 1 and the secondary anchor rod 101 are radially distributed. The width of the bottom reinforcing platform 204 is the same as the width of the internal groove 206. The positions of bolt holes 205 and 208 correspond to each other. The main connecting platform 201 has two sets of plug-in blocks 209 fixedly connected to both sides. Two sets of snap-fit ​​grooves 210 are formed on the surface of each plug-in block 209 to increase the contact area between the plug-in block 209 and subsequent parts. The secondary connecting platform 202 has two sets of fixing grooves 211 on the side closest to the main connecting platform 201. Two sets of snap-fit ​​blocks are fixedly connected to the bottom wall of the fixing grooves 211, and the size of the snap-fit ​​blocks is the same as that of the snap-fit ​​grooves 210. The fixing grooves 211 engage and limit the plug-in blocks 209. Through the cooperation of the main anchor rod 1 and the reinforcement mechanism 2, the plug-in blocks 209 and the fixing grooves 211 are connected. The cooperation of the two components allows the plug-in block 209 to engage with the fixing groove 211, and the locking block inside the fixing groove 211 to engage with the locking groove 210, thereby achieving the initial connection between the main connecting platform 201 and the auxiliary connecting platform 202. The cooperation between the bottom reinforcing platform 204 and the internal groove 206 further strengthens the splicing. The cooperation between the wrapping plate 207 and the bottom reinforcing platform 204 limits the bottom reinforcing platform 204, and the cooperation between the bolt hole 208 and the bolt hole 205 strengthens the overall strength of the structure. Thus, the main anchor rod 1 and the auxiliary anchor rod 101 are assembled in a radial shape, thereby improving the stability of the structure.

[0025] Refer to the instruction manual appendix Figure 1-5Both the main anchor rod 1 and the secondary anchor rod 101 have two sets of V-shaped blocks 4 threadedly connected to their surfaces. Several sets of deepening grooves 5 are opened at the bottom of the V-shaped blocks 4. The cooperation between the V-shaped blocks 4 and the deepening grooves 5 increases the contact area with the soil and prevents it from rising or loosening due to buoyancy. Both the main anchor rod 1 and the main anchor rod 101 have net mats 6 laid on their tops. The top of the net mats 6 is provided with mesh bolts 3, and the mesh bolts 3 are threadedly connected to the top of the main anchor rod 1. The mesh mats 6 are fixed to the top of the main anchor rod 1 by the mesh bolts 3, thereby improving stability.

[0026] The working principle of this practical application is as follows:

[0027] Refer to the instruction manual appendix Figure 1-5 In the event of a pipe rupture, a large flow of water impacts the anchor bolt. The V-shaped block 4, in conjunction with the deepened groove 5, increases the contact area with the soil, preventing it from rising or loosening due to buoyancy. Simultaneously, the mesh bolts 3 secure the mesh pad 6 to the top of the main anchor bolt 1, thereby enhancing the structure's stability through the connection between the mesh bolts 3 and the soil. Furthermore, the insertion block 209 engages with the fixing groove 211, and the locking block inside the fixing groove 211 engages with the locking groove 210, thus achieving the initial connection between the main connecting platform 201 and the auxiliary connecting platform 202. This also increases the contact area between the insertion block 209 and the fixing groove 211, making it more resistant to stress. The uniformity of the reinforcement increases the stability of the connection. By utilizing the cooperation between the bottom reinforcement platform 204 and the internal groove 206, the reinforcement mounting block 203 is inserted into the internal groove 206, thereby further strengthening the splicing. The bottom reinforcement platform 204 is limited by the cooperation between the wrapping plate 207 and the bottom reinforcement platform 204. The bottom reinforcement platform 204, the wrapping plate 207 and the reinforcement mounting block 203 are connected into a whole by bolts through the cooperation between bolt hole 208 and bolt hole 205, thereby strengthening the overall strength of the structure. The main anchor rod 1 and the secondary anchor rod 101 are assembled in a radial shape. The radial distribution enhances the resistance to rigid failure, thereby improving the stability of the structure.

[0028] 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.
