Description

Technical Field

[0001] The present invention relates to the technical field of slope protection, and in particular to a reinforcement device, a reinforcement component and an installation method of the reinforcement device. Background Art

[0002] Slope landslide disasters have long plagued human safety production activities. Expansive soil is a special soil with expansion and contraction and water absorption and softening properties. At the same time, a variety of weak structural surfaces are widely developed inside. Therefore, expansive soil areas are prone to landslide disasters. However, a large number of highway projects in my country pass through expansive soil areas, and road cutting excavation and embankment filling are inevitable. The adverse consequences caused by slope disasters have a huge impact.

[0003] In recent years, the frequent instability of expansive soil highway slopes has seriously affected normal construction operations and caused significant economic losses. Among expansive soil landslides, sliding failure along the existing structural surface inside the soil layer is a major form of expansive soil slope failure, which can occur in both the cut slope and the embankment slope. The failure of expansive soil slopes is mainly due to the extensive development of internal weak structural surfaces. Under the influence of construction loads, the weak structural surfaces form stress concentration zones, which are prone to further sliding and penetrating to form sliding surfaces, resulting in serious instability of the slopes. For expansive soil, under rainfall infiltration conditions, the strength of the weak structural surface is further reduced, and the slope will be more likely to slide along the weak layer.

[0004] However, before the expansive soil slope landslides, the slope has basically undergone significant deformation, while conventional anchor rods only use ordinary material steel strands, which have a small allowable deformation and are broken before the landslide occurs, thus losing the reinforcement effect. Summary of the invention

[0005] Based on this, it is necessary to provide a reinforcement device, a reinforcement assembly and an installation method of the reinforcement device that can increase the deformation to maintain the reinforcement effect in order to address the above problems.

[0006] A reinforcement device comprises an anchor rod structure, a frame beam structure, an end cover and a damping assembly, wherein the frame beam structure is arranged at one end of the anchor rod structure, the end cover is sleeved on the other end of the anchor rod structure, and the anchor rod structure can slide relative to the end cover; the damping assembly is arranged between the anchor rod structure and the end cover, and is used to increase the friction force when the anchor rod structure slides relative to the end cover; in a protective state, the frame beam structure is laid on the slope surface of an expansive soil slope, and the end cover is fixed to a stabilizing body.

[0007] Preferably, in one of the embodiments, the damping assembly comprises:

[0008] a first damping component, wherein the first damping component is fixed to an end of the anchor structure;

[0009] The second damping component is arranged inside the end cover, and the second damping component is pressed against the first damping component.

[0010] Preferably, in one of the embodiments, the reinforcement device further comprises:

[0011] A sensor component is arranged on the anchor structure, and is used to measure the axial force of the anchor structure and convert the axial force into an electrical signal for output.

[0012] Preferably, in one embodiment, the reinforcement device also includes a receiving component, a processing component and a display component; wherein the receiving component is signal-connected to the sensing component and the processing component, respectively, and the processing component is signal-connected to the display component; after receiving the electrical signal through the receiving component, the processing component is used to process the electrical signal to obtain a processing result, and send the processing result to the display component; the display component is used to receive and display the processing result.

[0013] Preferably, in one of the embodiments, the sensor assembly comprises a vibrating-wire load sensor, and the vibrating-wire load sensor is sleeved on the circumference of the anchor structure.

[0014] Preferably, in one of the embodiments, the reinforcement device further comprises a locking assembly, wherein the locking assembly is disposed at an end of the anchor rod structure, and the frame beam structure is movably sleeved on the anchor rod structure.

[0015] Preferably, in one of the embodiments, the sensor assembly is disposed between the locking assembly and the frame beam structure.

[0016] Preferably, in one of the embodiments, the reinforcement device further comprises:

[0017] A telescopic sleeve, wherein the telescopic sleeve is sleeved on the anchor rod structure, and one end of the telescopic sleeve is fixedly connected to the frame beam structure, and the other end of the telescopic sleeve is fixedly connected to the end cover.

[0018] Preferably, in one of the embodiments, the telescopic sleeve and the end cover are integrally formed.

[0019] A reinforcement assembly comprises any one of the above-mentioned reinforcement devices and a stabilizing body, wherein the frame beam structure is arranged above the slope surface of the stabilizing body and together with the stabilizing body forms an inverted cone-shaped space for accommodating the expansive soil slope.

[0020] A method for installing a reinforcement device, used for installing any one of the above reinforcement devices, comprising:

[0021] Anchor holes in the expansive soil slope and the stabilizing body form mounting holes;

[0022] Pre-installing the end cover, the damping assembly and the anchor rod structure to obtain a pre-installed assembly, and installing the pre-installed assembly into the installation hole;

[0023] injecting grout between the mounting hole and the end cover;

[0024] The frame beam structure and the anchor rod structure are connected.

[0025] The above-mentioned reinforcement device includes an anchor structure and a damping component that can resist a certain displacement. When the slope undergoes a large convergence deformation along the sliding surface, the tension of the anchor structure will further increase, causing the damping component to slide. During the sliding process of the damping component, the anchor structure will not be broken, and the deformation of the surrounding rock is resisted by the movement of the damping component, thereby improving the slope's anti-sliding force and the overall stability of the slope. When the slope further slides along the potential sliding surface, the damping component deforms too much, exceeding the deformation range of the damping component, and the anchor structure is broken, losing the reinforcement monitoring effect. The device can not only reinforce the expansive soil slope through the anchor structure before the landslide, but also release the force of the sliding of a small-scale landslide body in the early stage of the landslide, and then continue to reinforce the expansive soil slope through the anchor structure, so as to increase the deformation amount of the slope body that the reinforcement device can reinforce, and improve the reinforcement effect of the reinforcement device.

[0026] The above-mentioned reinforcement assembly includes a reinforcement device and a stabilizing body. Through the cooperation of the reinforcement device and the stabilizing body, stable support for the expansive soil slope within a certain deformation range is achieved, the reinforcement effect of the reinforcement device on the expansive soil slope and the stabilizing body is optimized, and the application scope of the reinforcement assembly is expanded.

[0027] The installation method of the reinforcement device has simple operation steps and low operation difficulty, thereby improving the operability of the reinforcement device.

[0043] In one of the application scenarios, the reinforcement device 10 in the present application is used to reinforce a slope, wherein the slope includes an expansive soil slope 20 and a stabilizing body 30. The stabilizing body 30 has an inclined slope surface, the expansive soil slope 20 is laid on the slope surface of the stabilizing body 30, and forms a slope surface of the expansive soil slope 20, and a potential sliding surface 40 is formed between the expansive soil slope 20 and the stabilizing body 30 along the slope surface of the stabilizing body 30. When the expansive soil slope 20 absorbs water and swells, it will slide relative to the stabilizing body 30 along the potential sliding surface 40. Specifically, the stabilizing body 30 can be a stable rock mass. The expansive soil slope is a slope composed of expansive soil, which is also called expansive soil. It is a clay soil that expands violently after being immersed in water and shrinks significantly after losing water. The expansive soil is highly hydrophilic, and its strength decreases significantly after absorbing water, so it will cause serious harm to highway engineering and slope engineering.

[0044] In one embodiment, see Figures 1 to 7A reinforcement device 10 includes an anchor structure 100, a frame beam structure 200, an end cover 300 and a damping assembly 400. Specifically, the anchor structure 100 is a steel strand 110 that passes through a potential sliding surface 40. The frame beam structure 200 is disposed at one end of the anchor structure 100, and the end cover 300 is sleeved on the other end of the anchor structure 100, and the anchor structure 100 can slide relative to the end cover 300. The damping assembly 400 is disposed between the anchor structure 100 and the end cover 300, and is used to increase the friction force when the anchor structure 100 slides relative to the end cover 300. In the protective state, the frame beam structure 200 is laid on the slope surface of the expansive soil slope 20, and the end cover 300 is fixed to the stabilizing body 30.

[0045] During use, the anchor structure 100 is fixed to the slope surface of the expansive soil slope 20 through the frame beam structure 200, and the other end is anchored in the stable rock mass within the potential sliding surface 40 through the end cover 300, so as to generate anti-slip resistance directly on the potential sliding surface 40 through the anchor structure 100, increase the anti-slip friction resistance, and put the structural surface in a compressed state, so as to improve the integrity of the expansive soil slope 20 and the stabilizing body 30, thereby fundamentally improving the mechanical properties of the slope, effectively controlling the displacement of the expansive soil slope 20, promoting the stability of the slope, and achieving the purpose of regulating the layer, landslides, dangerous rocks and stones.

[0046] The above-mentioned reinforcement device includes an anchor structure and a damping component that can resist a certain displacement. When the slope undergoes a large convergence deformation along the sliding surface, the tension of the anchor structure will further increase, causing the damping component to slide. During the sliding process of the damping component, the anchor structure will not be broken, and the deformation of the surrounding rock is resisted by the movement of the damping component, thereby improving the slope's anti-sliding force and the overall stability of the slope. When the slope further slides along the potential sliding surface, the deformation of the damping component is too large, exceeding the deformation range of the damping component, and the anchor structure is broken, losing the reinforcement monitoring effect. The device can not only reinforce the expansive soil slope through the anchor structure before the landslide, but also release the force of the sliding of a small-scale landslide body in the early stage of the landslide, and then continue to reinforce the expansive soil slope through the anchor structure, so as to increase the deformation of the slope body that the reinforcement device can reinforce, and improve the reinforcement effect of the reinforcement device.

[0047] In one embodiment, see Figures 4 to 7 The damping assembly 400 includes a first damping component 410 and a second damping component 420. The first damping component 410 is fixed to the end of the anchor structure 100, and the second damping component 420 is disposed inside the end cover 300, and the second damping component 420 is pressed against the first damping component 410. The first damping component 410 and the second damping component 420 cooperate to increase the friction between the anchor structure 100 when the anchor structure 100 moves relative to the end cover 300.

[0048] In one preferred embodiment, the first damping component 410 includes a first serrated portion, and the second damping component 420 includes a second serrated portion that is opposite in shape to the first serrated portion and is arranged opposite to the first serrated portion, and the first serrated portion cooperates with the second serrated portion to facilitate the first damping component 410 to be pressed against the second damping component 420.

[0049] In the above-mentioned reinforcement device, the damping assembly includes a first damping component arranged at the end of the anchor rod structure and a second damping component inside the end cover, which prevents friction loss when the anchor rod structure slides relative to the end cover, realizes a stable connection of the damping assembly between the anchor rod structure and the end cover, and reduces the difficulty of installing the first damping component and the second damping component.

[0050] In one specific embodiment, the first damping component 410 is a damping body, and the second damping component 420 is a damper. Preferably, the damping body is a friction damping body.

[0051] Specifically, before the slope loses stability, when the expansive soil slope 20 has only a small displacement, the tension on the anchor structure 100 is less than the tension that causes the damper to slip, and the damper does not move. At this time, the deformation of the expansive soil slope 20 is resisted by the elastic deformation of the anchor structure 100. When the slope begins to lose stability, the displacement of the expansive soil slope 20 increases, and the deformation of the expansive soil slope 20 causes the tension on the anchor structure 100 to be greater than the tension that causes the damping body to slip. The damper along the inner wall of the end cover slips. At this time, the deformation of the expansive soil slope 20 is resisted by the movement of the damping body, and after the damping body is displaced, the deformation of the expansive soil slope 20 can be released, and then it is in a stable state again. When the slope is completely unstable, the slope displacement increases further, the damper along the inner wall of the end cap continues to slide, and the friction force generated by the movement of the damper by the anchor structure 100 cannot resist the downward force of the expansive soil slope 20. The damper is pulled out of the damper, and the anchor structure 100 loses its reinforcement effect. At this time, the total deformation of the anchor structure is the tensile length of the anchor structure 100 plus the sliding length of the damper, that is, the total deformation of the anchor structure 100 is much greater than the total deformation of the ordinary anchor, which improves the effect of resisting the deformation of the expansive soil slope 20.

[0052] In one embodiment, see Figures 4 to 7, the reinforcement device 10 also includes a sensor component 500. The sensor component 500 is arranged on the anchor structure 100, and is used to measure the axial force of the anchor structure 100, and convert the axial force into an electrical signal output, wherein the axial force is used to characterize the deformation and displacement of the anchor structure 100. Since the downward sliding force of the expansive soil slope 20 is greater than the anti-sliding force of the stabilizing body 30, which is a necessary and sufficient condition for the slope to slide, the sensor component 500 is arranged in the expansive soil slope 20 to detect the deformation and displacement of the anchor structure 100, judge the state of the anchor structure 100, and then judge the sliding state of the slope. When the potential sliding surface 40 of the expansive soil slope is affected by rainwater infiltration and the mechanical parameters of the weak layer of the expansive soil decrease, or when the load on the top of the slope increases, the residual sliding force of the slope increases, and the axial force of the anchor structure 100 increases. The sensor component measures and displays, and realizes real-time monitoring of the downward sliding force of the slope.

[0053] The above reinforcement device can monitor the axial force of the anchor structure in real time by setting up a sensor component, and then obtain the deformation and displacement of the anchor structure according to the axial force to monitor the deformation degree of the slope, realizing an integrated system for monitoring the reinforcement of expansive soil landslide disasters. Compared with the traditional monitoring methods of expansive soil slope engineering, which are mostly based on phenomenon observation and empirical methods, it can directly monitor the relationship between sliding force and anti-sliding force. At the same time, it can still continuously monitor the changes in the internal force of the anchor when the landslide body slides in a small range, divide and warn the changing trend of the sliding force and the development stage of the landslide, and realize the integrated function of reinforcement monitoring.

[0054] In one embodiment, the reinforcement device 10 further includes a receiving component (not shown), a processing component (not shown) and a display component (not shown). The receiving component is respectively connected to the sensing component 500 and the processing component by signal, and the processing component is connected to the display component by signal. After receiving the electrical signal through the receiving component, the processing component is used to process the electrical signal to obtain a processing result, and send the processing result to the display component; the display component is used to receive and display the processing result. Specifically, the display component can be a display or a reading device.

[0055] The above-mentioned reinforcement device is provided with a receiving component, a processing component and a display component. The receiving component receives the electrical signal emitted by the sensor component, and then processes the electrical signal through the processing component and sends it to the display component for display, thereby realizing effective processing and visual display of the electrical signal, thereby clearly displaying the axial force on the anchor structure, and optimizing the monitoring result of the reinforcement device.

[0056] Specifically, the reinforcement device passes the anchor structure 100 through the potential sliding surface 40 of the expansive soil slope 20, so that the sliding surface 40 is deformed when there is a sliding tendency, and the axial tension of the anchor structure 100 increases accordingly.

[0057] Furthermore, according to the axial force of the anchor structure 100 measured by the sensor assembly 500, a stress-strain curve of the anchor structure 100 is generated, and a monitoring and early warning plan for the expansive soil slope 20 can be formulated based on this curve. Specifically, during the process of slope instability, the stress-strain curve of the anchor structure 100 has an ideal elastic-plastic deformation stage. In the elastic stage of the anchor structure 100, it is planned that the period before 60% of the ultimate tensile force of the anchor structure 100 is a safe stage. After the stress of the anchor structure 100 exceeds this value, it is necessary to strengthen displacement observation to find out whether the surface and deep deformation of the slope will continue to develop; when the stress of the anchor structure 100 exceeds 80% of the ultimate tensile strength, an early warning should be issued, and reinforcement measures should be taken in time when the stress of the anchor structure 100 reaches the ultimate tensile strength and a large deformation occurs, so as to ensure the safety of the slope.

[0058] In one embodiment, the sensor assembly 500 includes a vibrating wire load sensor. The vibrating wire load sensor is sleeved on the circumference of the anchor structure 100.

[0059] The reinforcement device sets the sensor component as a vibrating string load sensor, that is, a resonant sensor with a taut metal string as a sensitive element. When the length of the string is determined, the change in its natural vibration frequency can represent the magnitude of the tension on the string. Through the corresponding measurement circuit, an electrical signal with a certain relationship with the tension can be obtained, which improves the accuracy, sensitivity and stability of the sensor component and reduces the difficulty of installing the sensor component.

[0060] In one embodiment, see Figures 4 to 7 The reinforcement device 10 further includes a locking assembly 700, which is disposed at the end of the anchor structure 100, and the frame beam structure 200 is movably sleeved on the anchor structure 100. In the above reinforcement device, the locking assembly is disposed at the end of the anchor structure, and the frame beam structure is disposed between the locking assembly and the end cap. The locking assembly prevents the frame beam structure from slipping off the anchor structure, thereby ensuring the stability of the overall structure.

[0061] In one embodiment, the sensor assembly 500 is disposed between the locking assembly 700 and the frame beam structure 200. Specifically, the sensor assembly 500 is sleeved on the anchor structure 100 and is located between the locking assembly 700 and the frame beam structure 200. In the above reinforcement device, the sensor assembly installed on the anchor structure realizes the measurement and reading of the change law of the anchor axial force, thereby obtaining the change trend of the sliding force, and realizes the integration of reinforcement monitoring of the expansive soil slope. The installation steps of the sensor assembly of the above reinforcement device are simple and the installation difficulty is relatively low.

[0062] In one embodiment, see Figures 4 to 7The reinforcement device 10 further includes a telescopic sleeve 600 , which is sleeved on the anchor structure 100 , and one end of the telescopic sleeve 600 is fixedly connected to the frame beam structure 200 , and the other end of the telescopic sleeve 600 is fixedly connected to the end cover 300 .

[0063] The above reinforcement device meets the demand for axial deformation of the anchor structure by arranging a telescopic sleeve around the anchor structure, ensures the surrounding working environment during the deformation of the anchor structure, improves the overall stability, and optimizes the overall structure of the reinforcement device.

[0064] In one embodiment, the telescopic sleeve 600 and the end cover 300 are integrally formed.

[0065] The above reinforcement device reduces the number of components of the reinforcement device, simplifies the installation steps of the reinforcement device, and improves the installation efficiency of the reinforcement device by integrating the telescopic sleeve and the end cover.

[0066] In one embodiment, see Figures 1 to 3 A reinforcement assembly includes any one of the above-mentioned reinforcement devices 10 and a stabilizing body 30, a frame beam structure 200 is arranged above the slope of the stabilizing body 30, and the frame beam structure 200 and the stabilizing body 30 together form a space for accommodating the expansive soil slope 20. In order to reduce the volume of the expansive soil while ensuring support, preferably, the space between the frame beam structure 200 and the stabilizing body 30 is an inverted cone space. It can be understood that the inverted cone space refers to a space structure with an inverted cone cross section along the seepage direction. Among them, the expansive soil slope 20 is laid on the slope of the stabilizing body 30, and the frame beam structure 200 is laid on the slope of the expansive soil slope 20. The above-mentioned reinforcement assembly includes a reinforcement device and a stabilizing body. Through the cooperation of the reinforcement device and the stabilizing body, stable support for the expansive soil slope within a certain deformation range is achieved, the reinforcement effect of the reinforcement device on the expansive soil slope and the stabilizing body is optimized, and the application range of the reinforcement assembly is increased.

[0067] In one embodiment, the method for installing the reinforcement device includes:

[0068] Step 1: Anchor holes are formed into installation holes in the expansive soil slope 20 and the stabilizing body 30;

[0069] Step 2: pre-install the end cap 300, the damping assembly 400 and the anchor structure 100 to obtain a pre-assembled assembly, and install the pre-assembled assembly into the installation hole;

[0070] Step 3: Perform grouting reinforcement on the outside of the end cover 300 in the installation hole.

[0071] Step 4: Connect the frame beam structure 200 to the anchor structure 100 passing through the expansive soil slope 20 .

[0072] The installation method of the reinforcement device has simple operation steps and low operation difficulty, thereby improving the operability of the reinforcement device.

[0073] In one of the preferred embodiments, the installation method of the reinforcement device further comprises step 5: applying prestress to the anchor structure 100. Preferably, the applied prestress is 60%-70% of the maximum resistance value of the damper.

[0074] The installation method of the reinforcement device applies prestress to the anchor structure to tension the anchor structure, and the pressure of the tensioned anchor structure on the structural surface can effectively resist the displacement of the expansive soil slope along the structural surface, effectively reducing the possibility of slope instability and damage.

[0075] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
