Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, specifically a slope reinforcement device for municipal buildings. Background Technology

[0002] Slopes are widely used in road widening, underground pipeline laying, park and green space construction, and river regulation. These slopes are mostly formed by artificial excavation or natural terrain modification. Affected by geological conditions, hydrological environment, and external loads, they are prone to soil slippage, slope collapse, and other hidden dangers. This not only damages the integrity of municipal facilities but may also threaten the safety of pedestrians and traffic order. Therefore, slope reinforcement has become one of the core aspects of municipal engineering construction and maintenance.

[0003] In existing slope reinforcement devices, some fixation is achieved by inserting rods into the slope. However, these rods are mostly smooth cylinders or simple threaded structures, resulting in insufficient interlocking force with the surrounding soil. Long-term soil compression or external vibration can easily cause loosening, leading to decreased reinforcement stability and difficulty in resisting slope slippage risks in the long term. This problem is particularly prominent in steep slopes or loose soil layers. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to provide a slope reinforcement device for municipal buildings, which solves the problem in the existing slope reinforcement devices mentioned in the background art, in which some are fixed by inserting rods into the slope, but the rods are mostly smooth cylinders or simple threaded structures, which have insufficient interlocking force with the surrounding soil, and are prone to loosening due to long-term soil compression or external vibration, resulting in a decrease in reinforcement stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slope reinforcement device for municipal buildings, comprising a support frame, the side wall of the support frame having a plurality of slots, the inner wall of the slots having a threaded line, the inner side of the slots being threadedly connected to a threaded post, the threaded post having a hollow channel inside, and the surface of the threaded post having a plurality of equidistantly arranged telescopic grooves, the inner side of the telescopic grooves being slidably connected to a telescopic block, the telescopic grooves communicating with the hollow channel inside the threaded post, and the inner side of the threaded post having an inner rod.

[0006] In this technical solution, several threaded columns are installed on the side wall of the support frame and inserted into the slope wall to enhance stability. Expansion grooves and expansion blocks are also installed. After the inner rod is screwed in, the expansion blocks are pushed out of the expansion grooves and inserted into the soil to form a double reinforcement structure. This greatly enhances the anchoring force between the threaded columns and the soil, effectively prevents the rod from loosening, and significantly improves the long-term stability of the slope reinforcement.

[0007] Preferably, the inner wall of the opening of the hollow channel of the threaded column is provided with a thread, and the surface of the inner rod corresponding to the opening of the hollow channel of the threaded column is also provided with a thread. The inner rod is threadedly connected to the threaded column through the thread. A second rotating wheel is fixedly connected to the outer end of the inner rod, and a first rotating wheel is fixedly connected to the outer end of the threaded column.

[0008] Preferably, the inner rod has a water guide groove inside, and the inner rod surface on one side of the second rotating wheel has a drain hole, which is connected to the water guide groove.

[0009] Preferably, the surface of one end of the threaded column inserted into the slope is provided with a plurality of water inlets in a circumferential array, and a filter screen is provided at the opening of the water inlet. The water inlet is connected to the hollow channel inside the threaded column.

[0010] Preferably, a spring is sleeved on the surface of the telescopic block, and the end of the telescopic block facing the outside of the threaded post is on the same plane as the surface of the threaded post. The threaded post surface at the corresponding position of the telescopic block is provided with an annular groove, and the end of the telescopic block facing the inside of the threaded post passes through the telescopic groove and is located inside the annular groove.

[0011] Preferably, the horizontal surface of the support frame is provided with rivets, and both the left and right side walls of the support frame are provided with side holes for splicing.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model strengthens stability by setting several threaded columns on the side wall of the support frame and inserting them into the slope wall. It also sets expansion grooves and expansion blocks. After the inner rod is screwed in, the expansion blocks are pushed out of the expansion grooves and inserted into the soil, forming a double reinforcement structure. This greatly enhances the anchoring force between the threaded columns and the soil, effectively prevents the rod from loosening, and significantly improves the long-term stability of the slope reinforcement.

[0014] 2. This utility model, by screwing in the inner rod, after the inner rod is fully inserted into the threaded column, connects the water guide channel with the water inlet. The water accumulated in the slope soil can enter the hollow channel through the water inlet with a filter screen, and then be discharged from the drainage hole through the water guide channel, realizing the orderly flow of water, reducing the erosion of the soil structure by water accumulation, reducing the risk of soil erosion, and further assisting in improving the slope reinforcement effect.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0022] A slope reinforcement device for municipal buildings, see [link / reference] Figures 1 to 4 The system includes a support frame 1, the side wall of which is provided with several insertion ports 103, the inner wall of which is provided with threads, and a threaded post 2 is threadedly connected to the inner side of the insertion port 103. The threaded post 2 has a hollow channel inside, and an inner rod 3 is provided inside the threaded post 2. The surface of the threaded post 2 is provided with several equidistantly arranged telescopic grooves 6, and a telescopic block 7 is slidably connected to the inner side of the telescopic grooves 6. The inner wall of the opening of the hollow channel of the threaded post 2 is provided with threads, and the surface of the inner rod 3 corresponding to the opening of the hollow channel of the threaded post 2 is also provided with threads. The inner rod 3 is threadedly connected to the threaded post 2 through the threads. A second rotating wheel 301 is fixedly connected to the outer end of the inner rod 3, and a first rotating wheel 201 is fixedly connected to the outer end of the threaded post 2.

[0023] In the above technical solution, during construction, the support frame 1 is first fixed to the top of the slope or platform by the rivets 101 on the horizontal surface of the support frame 1. Then, the first rotating wheel 201 is rotated, and the threaded engagement between the socket 103 and the threaded column 2 is used to screw the threaded column 2 into the slope soil to complete the initial fixation. Subsequently, the second rotating wheel 301 is rotated, and through the threaded transmission between the inner rod 3 and the threaded column 2, the inner rod 3 is pushed into the soil along the hollow channel of the threaded column 2, so that the telescopic block 7 is inserted into the soil, forming a double reinforcement structure. This can enhance the initial bonding force between the rod and the soil, enhance the anchoring force between the threaded column 2 and the soil, effectively prevent the rod from loosening, and significantly improve the long-term stability of the slope reinforcement.

[0024] Specifically, such as Figure 4As shown, the telescopic groove 6 is connected to the hollow channel inside the threaded column 2. A spring 701 is sleeved on the surface of the telescopic block 7, and the end of the telescopic block 7 facing the outside of the threaded column 2 is on the same plane as the surface of the threaded column 2. During the process of the threaded column 2 being screwed into the soil, the telescopic block 7, because its surface is flush with the threaded column 2, will not obstruct the normal rotation and forward movement of the threaded column 2, ensuring that the threaded column 2 is smoothly inserted. The spring 701 is in a natural extension and contraction state, which constrains the telescopic block 7 and prevents it from popping out for no reason. At the same time, the telescopic block 7 can be reset when the inner rod 3 is turned.

[0025] It is worth noting that, such as Figure 4 As shown, the surface of the threaded post 2 at the corresponding position of the telescopic block 7 is provided with an annular groove 8. The end of the telescopic block 7 facing the inner side of the threaded post 2 passes through the telescopic groove 6 and is located inside the annular groove 8. Under normal conditions, the annular groove 8 provides storage space for the telescopic block 7. When the inner rod 3 rotates, the annular groove 8 and the telescopic block 7 are misaligned. At this time, the telescopic block 7 will be pushed out of the telescopic groove 6 and inserted into the soil. Through the mechanical linkage of the inner rod 3 pushing and the spring 701 resetting, the telescopic block 7 can automatically extend and retract. The extended telescopic block 7 can form a lateral engagement with the soil, which greatly improves the anchoring strength of the threaded post 2.

[0026] Furthermore, such as Figure 4 As shown, the inner rod 3 has a water guide channel 4 inside, and the inner rod 3 has a drainage hole 401 on one side of the second rotating wheel 301. The drainage hole 401 is connected to the water guide channel 4. The end of the threaded column 2 that is inserted into the slope has several water inlets 5 arranged in a circular array. The opening of the water inlet 5 is equipped with a filter screen 501, and the water inlet 5 is connected to the hollow channel inside the threaded column 2. When the inner rod 3 is fully screwed into the threaded column 2, the water guide channel 4 is connected to the hollow channel of the threaded column 2. The water accumulated in the slope soil will seep into the hollow channel through the water inlet 5, then flow into the water guide channel 4, and finally be discharged from the drainage hole 401 to the drainage system outside the slope. By orderly guiding the water, the erosion of the soil structure by the water is reduced, the risk of soil erosion is reduced, and the slope reinforcement effect is further improved.

[0027] It is worth noting that, such as Figure 1 As shown, the horizontal surface of the support frame 1 is provided with rivets 101, and the left and right side walls of the support frame 1 are provided with side holes 102 for splicing; the support frame 1 is fixed to the slope foundation or platform ground by the rivets 101 to ensure that the support frame 1 itself does not shift; when the reinforcement range is large, multiple support frames 1 can be connected by bolts through the side holes 102 to form a continuous reinforcement frame, so that the anchoring force of the threaded column 2 is transmitted to each other through the support frame 1 to form an overall reinforcement system.

[0028] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
