Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a protective structure capable of effectively preventing covering soil on a slope from sliding off, and a construction method of the structure. Background Art

[0002] Slope landscapes play a vital role in urban planning, garden design and nature reserves. They not only beautify the environment and provide space for leisure and entertainment, but also play a positive role in soil and water conservation and ecological restoration. However, in practical applications, slope landscapes face many challenges, especially in preventing the cover soil from sliding.

[0003] One of the traditional anti-slip measures is to reinforce the soil by planting vegetation. Although this method can reduce soil erosion to a certain extent, for those areas with complex geological conditions or heavy rainfall, relying solely on vegetation cover is often not enough to prevent large-scale soil sliding.

[0004] The vegetation growth cycle is long and cannot immediately play a stabilizing role in the initial stage; at the same time, the selection and maintenance of plants also require professional knowledge and technical support.

[0005] Laying ordinary grids is a common practice, but this structure is usually only suitable for small, low-angle slopes, and its tensile strength is limited. It is prone to aging and damage due to long-term exposure, resulting in reduced protective effects.

[0006] For slopes near some key infrastructure, concrete pouring may be used for protection. This method can indeed provide strong support, but it also has obvious disadvantages: the construction cost is high, the construction process is complicated and time-consuming, and once built, it is almost irreversible, which is not conducive to later adjustment or transformation.

[0007] In many existing slope protection projects, the drainage system is not well set up. When encountering heavy rainfall, if the rainwater cannot be discharged in time, it will accumulate inside the slope, increase the soil moisture content, and thus increase the risk of landslides. Imperfect drainage facilities will also accelerate soil erosion and shorten the service life of the protection structure.

[0008] Most existing slope protection projects lack real-time monitoring methods and cannot timely grasp the changes in the slope status. This makes it difficult for managers to predict potential safety hazards in advance, increasing the possibility of sudden accidents. Without an effective early warning mechanism, once a landslide occurs, the emergency response speed will be affected, which may cause greater losses.

[0009] Therefore, a slope landscape anti-soil sliding protection structure and a construction method are proposed to solve the above problems. Summary of the invention

[0010] The present invention provides a slope landscape anti-slip soil protection structure and a construction method thereof, which aims to effectively prevent the soil covering the slope from sliding due to rainwater erosion or natural factors such as earthquakes by comprehensively using drainage systems, reinforcement layers, anchor fixation, and ecological restoration measures. The protection structure can not only significantly improve the stability of the slope, but also promote the restoration and beautification of the ecological environment, and is suitable for various types of slope projects.

[0011] The present invention provides a slope landscape anti-soil sliding protection structure, which mainly includes a drainage layer arranged at the bottom of the covering soil layer, and the drainage layer is provided with staggered and inclined water collection grooves, and the water collection grooves are collected into a vertical shaft;

[0012] A vertical shaft, which is filled with a layer of permeable material and the bottom of which is connected to a drainage pipe;

[0013] A reinforcement layer arranged on the slope surface, the reinforcement network is composed of a number of interconnected reinforcement units;

[0014] Anchor rods are inserted deep into the overburden layer, and the top of the anchor rods is connected to the reinforcement layer.

[0015] The present invention first sets a drainage layer at the bottom of the covering soil layer. The drainage layer is composed of staggered and inclined water collection tanks, which are finally collected in the vertical shaft, ensuring that the water can be discharged smoothly from the slope area to avoid water accumulation and loosening of the covering soil. The interior of the vertical shaft is filled with layered permeable materials of different particle sizes, from bottom to top and from outside to inside, which are coarse sand, pebbles and large stones, so as to optimize the permeability. The bottom of the vertical shaft is connected to the drain pipe through a waterproof joint to prevent external water from invading the vertical shaft and ensure the long-term effectiveness of the system.

[0016] Further describing the above scheme, the reinforcement layer covering the surface of the slope is composed of a number of interconnected reinforced concrete reinforcement units. Each reinforcement unit is not only filled with improved soil, but also pre-buried with reinforcing bars or steel mesh to improve the overall structural strength. In addition, a number of through holes are set on the reinforcement unit, which not only facilitates water penetration, but also provides growth space for plant roots, promotes ecological restoration and soil and water conservation, and relatively large through holes can be used to plant trees with more developed root systems, so that the reinforcement layer is stuck on the trunks and treetops.

[0017] More preferably, in order to ensure a firm bond between the reinforcement layer and the overburden layer, the present invention adopts anchor technology. The anchor goes deep into the overburden layer and is made of reinforced concrete material, with the top welded to the steel bars in the reinforcement layer. This design not only increases the anti-slip ability of the slope, but also effectively disperses the pressure applied by the outside world, making the entire protective structure more stable and reliable.

[0018] Furthermore, the present invention introduces an anchored retaining wall for the protection of the slope side. The retaining wall side is deeply anchored in the covering soil layer, and the wall surface is provided with drainage holes to reduce the lateral pressure. At the same time, permeable materials are arranged in the covering soil layer near the drainage holes to help quickly drain excess water, prevent soil erosion, and reduce the impact of water pressure on the retaining wall.

[0019] In order to monitor the state of the slope and take preventive measures in time, the present invention also sets a number of vertically arranged deformation sensors and humidity sensors inside the covering soil layer. These sensors can monitor the deformation and humidity changes of the slope in real time, and send the data to the remote monitoring center through the wireless transmission module. Once an abnormality is detected, a quick response can be made and necessary maintenance measures can be taken to ensure the safety of the slope.

[0020] Gravel, sand and soil layers were laid on the surface of the reinforcement layer in order to achieve good filtering and support effects. Vegetation suitable for local climate conditions was planted on the surface of the top soil layer, and local plant species with strong adaptability and drought and flood resistance were selected, which not only accelerated the ecological restoration process but also beautified the environment.

[0021] Optionally, the anchor rod is provided with at least two sections, and a deformation sensor rod body is installed between the anchor rods through a connecting sleeve. A deformation sensor is provided on the surface of the sensor rod body. When the overburden layer is offset or deformed, the deformation sensor is deformed and transmits a signal to the outside world. A number of grouting plugs are provided on the anchor rod to control the effective range of grouting and ensure that the slurry is only filled into the required part of the formation. A pad is installed on the top of the anchor rod, and the pad is connected and fixed to the reinforcement layer to evenly distribute the pressure transmitted from the anchor rod to prevent local stress concentration from causing structural damage.

[0022] The present invention also provides a construction method of a slope landscape anti-soil sliding protection structure, comprising the following steps:

[0023] Step 1: Carry out preliminary leveling of the slope and adjust the slope according to the design requirements.

[0024] Step 2: At the bottom of the leveled slope, start laying the drainage layer. The drainage layer consists of staggered and inclined troughs that eventually converge into the shaft. The design of the troughs needs to take into account the direction of water flow to ensure that it can smoothly divert water into the shaft. In order to improve drainage efficiency, the inclination angle of the trough should be appropriate and strictly controlled during construction to avoid water accumulation. The drainage layer material uses crushed stone or gravel with good water permeability to ensure long-term effective drainage performance.

[0025] Step 3: Backfill the overburden. During this process, the anchored retaining wall is built to ensure that the retaining wall is tightly combined with the overburden to avoid gaps. The retaining wall is cast with high-strength concrete, and the wall surface is equipped with drainage holes to reduce lateral pressure. A permeable material layer is set inside the overburden near the drainage holes to help quickly drain excess water and reduce the impact of water pressure on the retaining wall.

[0026] Step 3: Shaft excavation and layered backfilling of permeable materials: The shaft is excavated accurately at the selected location. The shaft depth must meet the design requirements and remain vertical. The shaft is backfilled with permeable materials of different particle sizes in the prescribed layered order, from bottom to top and from outside to inside, in the order of coarse sand, small gravel and large stones. Each layer of material must be fully compacted to optimize permeability and prevent material settlement. The bottom of the shaft is connected to the drain pipe through a waterproof joint.

[0027] Step 5: Drill holes at designated locations in the overburden layer, place anchor rods, and then pour high-performance cement mortar to fix them. The anchor rods penetrate deep into the overburden layer and are made of reinforced concrete. The top steel bars are firmly bonded to the reinforcement layer by welding. Subsequently, a reinforcement layer consisting of reinforced concrete reinforcement units is laid on the surface of the overburden layer. At the same time, deformation sensors and humidity sensors are installed in the overburden layer below the through holes on the reinforcement layer to ensure that these sensors are correctly placed so as to monitor the slope status in real time.

[0028] Step 6: Lay the gravel layer, sand layer and soil layer on the surface of the reinforcement layer from bottom to top. Each layer of material should be evenly distributed and fully compacted to form a good filtering and supporting effect. Ensure that the thickness of each layer of material is consistent to avoid uneven thickness, which will affect the stability and function of the overall structure.

[0029] Step 7: Select local plants with strong adaptability and drought and flood tolerance on the surface of the top soil layer to plant landscape vegetation. These plants not only beautify the environment, but also promote the ecological restoration process. When planting, attention should be paid to the spacing and layout between plants to ensure that they have enough growth space, and the irrigation system should be reasonably arranged according to the characteristics of the plants to promote the healthy growth of plants.

[0030] The present invention provides a slope landscape anti-slip protection structure and a construction method thereof, which significantly improves the stability and safety of the slope. By setting a reinforcement layer, anchor fixing and an efficient drainage system, the covering soil is effectively prevented from sliding due to natural factors such as rain erosion or earthquakes. The seamless splicing between reinforced concrete reinforcement units and the deep fixing of anchors ensure that the structure can remain stable in the face of external pressure.

[0031] The optimized drainage system consists of staggered and sloped troughs that eventually collect in the shaft and quickly drain the water through the connected drainage pipes, avoiding the problem of loose soil caused by water accumulation. At the same time, the permeable materials of different particle sizes filled in the shaft further improve the permeability and extend the service life of the protective structure.

[0032] The deformation sensors and humidity sensors installed in the covering layer can monitor the slope status in real time. Once an abnormal situation is detected, they can respond quickly and take necessary maintenance measures, providing reliable protection for the safety of the slope.

[0033] The anchor rod is combined with a deformation sensor, which is installed in a soft structure between two sections of the anchor rod solid, with a large height difference to ensure that the deformation can still be monitored when the covering soil is partially or completely offset.

[0034] In general, the present invention not only solves the problems existing in the traditional methods, but also brings significant improvements in many aspects, and has important application value and social benefits. Through the application of scientific and reasonable design and technical means, effective protection and ecological restoration of the slope are achieved, providing a solid guarantee for the safety and stability of the slope.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] To make the technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0046] See also Figure 1-Figure 3 As shown, a slope landscape anti-soil sliding protection structure provided by the present invention mainly includes a drainage layer, a vertical shaft 4, a reinforcement layer 5, and an anchor rod 51.

[0047] The drainage layer is arranged on the surface of the base soil layer 1, and the drainage layer is provided with staggered and inclined water collection tanks 2, which collect water into the vertical shaft 4. In some embodiments, the water collection tank 2 can also be used as a drainage tank to drain the water in the vertical shaft 4 and the overburden layer 3.

[0048] The vertical shaft 4 is filled with a water-permeable material layer 41 , and the bottom of the vertical shaft 4 is connected to the drainage pipe 11 . It should be noted that the bottom of the vertical shaft 4 can be the surface of the base soil layer 1 , or can go deep into the base soil layer 1 .

[0049] The reinforcement layer 5 is arranged on the slope surface. The reinforcement net is composed of a plurality of interconnected reinforcement units. Each reinforcement unit is provided with a planting hole 53 for planting plants to promote ecological restoration and soil and water conservation.

[0050] The anchor rod 51 penetrates deep into the overburden layer 3, and the top of the anchor rod 51 is connected to the reinforcement layer 5 to prevent the reinforcement layer 5 from deviating and sliding.

[0051] like Figure 1As shown, in this embodiment, the drainage layer is composed of staggered and inclined water collection tanks 2, which are finally collected in the vertical shaft 4, ensuring that the water flow can be smoothly discharged from the slope area to avoid the accumulation of water and loosening of the covering soil. The interior of the vertical shaft 4 is filled with layered permeable materials of different particle sizes, from bottom to top and from outside to inside, which are coarse sand, pebbles and large stones, so as to optimize the permeability. The bottom of the vertical shaft 4 is connected to the drain pipe 11 through a waterproof joint to prevent external water from invading the vertical shaft 4 and ensure the long-term effectiveness of the system.

[0052] like Figure 2 , 3 As shown, the reinforcement layer 5 covering the surface of the slope is composed of a number of interconnected reinforced concrete reinforcement units. The reinforcement unit is pre-buried with reinforcing ribs or steel mesh to improve the overall structural strength. In addition, a number of through holes are set on the reinforcement unit. The small through holes are water seepage holes 52, which not only help water penetration, but also provide growth space for plant roots, promote ecological restoration and soil and water conservation, and the larger through holes are planting holes 53. Planting holes 53 can be used to plant trees with relatively developed root systems, so that the reinforcement layer 5 is stuck on the tree trunks and tree tops, so that the trees act as anchors.

[0053] like Figure 1 , 2 As shown, the anchor rod 51 penetrates into the overburden layer 3 and is made of reinforced concrete material, and the top is welded to the steel bars in the reinforcement layer 5. This design not only increases the anti-slip ability of the slope, but also effectively disperses the pressure applied by the outside, making the entire protective structure more stable and reliable. The overburden layer 3 is deeply buried on the side of the retaining wall 9, and the wall surface is provided with drainage holes 31 to reduce lateral pressure. At the same time, a permeable material layer 41 is set in the overburden layer 3 near the drainage holes 31 to help quickly drain excess water. Prevent soil erosion and reduce the impact of water pressure on the retaining wall 9.

[0054] In order to monitor the state of the slope and take preventive measures in time, the present invention also sets a plurality of vertically arranged deformation sensors 32 and humidity sensors inside the covering layer 3. These sensors can monitor the deformation and humidity changes of the slope in real time, and send the data to the remote monitoring center through the wireless transmission module. Of course, the sensor can also be connected to the central controller on the slope, and the central controller is connected to the speaker. Once the deformation sensor 32 detects an abnormality, it can quickly alarm and remind tourists to leave.

[0055] In this embodiment, the anchor rod 51 and the deformation sensor 32 are integrated into one body. Figure 4As shown, the anchor rod 51 is provided with at least two sections, and a sensor rod body 514 is installed between the anchor rods 51 through a connecting sleeve 513. The anchor rod 51 and the sensor rod body 514 are hollow, and a deformation sensor is provided on the surface of the sensor rod body 514. A plurality of grouting plugs 512 are provided on the anchor rod 51 to control the effective range of grouting and ensure that the grout is only filled into the required part of the formation. A pad 515 is installed on the top of the anchor rod 51, and the pad 515 is connected and fixed to the reinforcement layer 5 to evenly distribute the pressure transmitted from the anchor rod 51 to prevent local stress concentration from causing structural damage.

[0056] The installation method of the anchor rod 51 is as follows: firstly, a plurality of sections of threaded anchor rods 51 are used to drill holes, and the bottom anchor rod 51 is provided with an anchor head 511, and a grouting hole is also provided on the anchor head 511. Figure 4 As shown, a stop plug 512 is installed on the top of the lower anchor rod 51. When the predetermined depth is reached, grouting can be injected, and the grouting will stop when the grout reaches the stop plug 512. When the grout solidifies, the anchor rods 51 above the bottom anchor rod 51 can be rotated and taken out.

[0057] Next, the sensor rod 514 is installed. The top of the sensor rod 514 is also provided with a stop plug 512, and the lower connection sleeve 513 is provided with a grouting hole. After the sensor rod 514 is connected to the bottom anchor rod 51 through the connection sleeve 513, the grout is directly injected. It should be noted that the grout around the sensor rod 514 is a soft structure after condensation. The grout can be silica gel. Grouting can be stopped when the stop plug 512 on the top of the sensor rod 514 is grouted.

[0058] Then continue to inject concrete slurry until the top of the upper anchor rod 51.

[0059] After grouting is completed, the rod body forms a solid-soft-solid structure from bottom to top. When the covering soil is partially or completely shifted, due to the large height difference of the anchor rod 51 and the deformation sensor installed between the two sections of solid, it can play a better role and will not easily shift with the covering soil as a whole, resulting in undetectable situations.

[0060] The deformation sensor uses strain gauge technology. In some embodiments, the deformation sensor is installed in the cover layer 3. The strain gauge deformation sensor measures stress and deformation by detecting the expansion and contraction and displacement changes on the surface of the material. When the slope moves or deforms, the sensor will immediately capture the change and convert it into an electrical signal.

[0061] After the signal is initially analyzed by the built-in data processing unit, the data is sent to the remote monitoring center through the transmission module. At the same time, the sensor can also be connected to the central controller on the slope to achieve local instant response. If abnormal deformation exceeding the preset threshold is detected, the central controller will trigger the alarm system and the speaker will sound a warning to remind visitors to quickly leave the danger zone.

[0062] Humidity sensors are mainly used to monitor changes in moisture content within the cover soil layer 3. Humidity sensors usually work based on capacitive or resistive principles, and determine humidity levels by detecting changes in the dielectric constant or resistivity of the soil. Capacitive humidity sensors consist of two parallel plates with soil as the medium filling the gap. As soil moisture increases, its dielectric constant increases, causing the capacitor capacity to change; resistive humidity sensors rely on changes in soil conductivity to reflect humidity changes.

[0063] Humidity sensors are also installed in the overburden layer 3, especially near the drainage layer and the sump 2, to ensure that the dynamic changes in moisture can be accurately captured. Once the humidity exceeds the set safety range, such as due to continuous rainfall causing moisture accumulation, the sensor will immediately transmit this information to the central control module and the remote monitoring center. Combined with the data from the deformation sensor, the stability of the slope can be more comprehensively assessed, and possible landslides can be warned in advance.

[0064] The data collected by all sensors are aggregated to a central processor, which is responsible for further analysis and processing of the data. Through wireless transmission modules such as LoRa, Zigbee or NB-I oT and other low-power wide area network LPWAN technologies, data can be stably and efficiently transmitted to the remote monitoring center. The monitoring center is equipped with a dedicated software platform for visualizing various indicators of the slope and providing historical data analysis functions to help managers better understand the long-term behavioral trends of the slope.

[0065] A gravel layer 6, a sand layer 7 and a soil layer 8 are laid on the surface of the reinforcement layer 5 to form a good filtering and supporting effect. The surface of the top soil layer 8 is planted with vegetation suitable for local climatic conditions, and local plant species with strong adaptability and drought and flood resistance are selected, which not only accelerates the ecological restoration process, but also beautifies the environment.

[0066] In order to have a more thorough and comprehensive understanding of the disclosure of the present invention, the principle thereof will be further explained in conjunction with the construction method below.

[0067] like Figure 5 As shown:

[0068] Step 1: Preliminary leveling of the slope

[0069] The preliminary leveling of the slope is the basis of the entire project. Use mechanical equipment, such as an excavator, to roughly level the slope to ensure that the slope surface is smooth and meets the predetermined design slope. It is recommended to use a laser rangefinder or a level gauge during the leveling process to ensure that the slope is accurate.

[0070] Step 2: Laying the drainage layer

[0071] At the bottom of the leveled slope, the drainage layer begins to be laid. The drainage layer consists of staggered and inclined water collection tanks 2, which eventually converge into the shaft 4. The design of the water collection tank 2 needs to take into account the direction of water flow to ensure that it can smoothly divert water to the shaft 4. In order to improve drainage efficiency, the inclination angle of the water collection tank 2 should be appropriate and strictly controlled during construction to avoid water accumulation. The drainage layer material uses crushed stone or gravel with good permeability to ensure long-term and effective drainage performance. It is recommended to lay a layer of geotextile as an isolation layer before laying to prevent fine particles from clogging the water collection tank 2 and affecting the drainage effect.

[0072] Step 3: Backfilling of the overburden layer 3 and simultaneous construction of the anchored retaining wall 9

[0073] The anchored retaining wall 9 is built while the overburden layer 3 is backfilled, ensuring that the retaining wall 9 is tightly combined with the overburden layer 3 to avoid gaps. The retaining wall 9 is cast with high-strength concrete, and a drainage hole 31 is provided on the wall surface to reduce lateral pressure. A permeable material layer 41 is provided inside the overburden layer 3 near the drainage hole 31 to help quickly drain excess water and reduce the impact of water pressure on the retaining wall 9. A certain thickness of sand and gravel mixture is filled behind the retaining wall 9 to enhance the stability of the wall and facilitate water discharge.

[0074] Step 4: Excavation of shaft 4 and backfilling with permeable materials in layers

[0075] The shaft 4 is excavated precisely at the selected location. The depth of the shaft 4 must meet the design requirements and remain vertical. The interior of the shaft 4 is backfilled with permeable materials of different particle sizes in the prescribed layered order, from bottom to top and from outside to inside, coarse sand, small gravel and large stones. Each layer of material must be fully compacted to optimize the permeability and prevent material settlement. The bottom of the shaft 4 is connected to the drain pipe 11 through a waterproof joint to ensure that external water sources will not invade the shaft 4 and maintain the long-term effectiveness of the system.

[0076] Step 5: Anchor rod 51 installation and reinforcement layer 5 laying

[0077] Drill holes at designated positions of the overburden layer 3, place anchor rods 51, and then pour high-performance cement mortar to fix them. The anchor rods 51 penetrate into the overburden layer 3 by at least 1 meter, and are made of reinforced concrete. The top steel bars are firmly bonded to the reinforcement layer 5 by welding. Subsequently, a reinforcement layer 5 consisting of reinforced concrete reinforcement units is laid on the surface of the overburden layer 3. Each reinforcement unit is not only filled with improved soil, but also pre-buried with reinforcing bars or steel mesh to improve the overall structural strength. In addition, a number of through holes are provided on the reinforcement unit, which not only help water penetration, but also provide growth space for plant roots, promoting ecological restoration and soil and water conservation. Larger through holes can be used to plant trees with more developed root systems, so that the reinforcement layer 5 is stuck on the trunk and tree top, further enhancing stability. At the same time, deformation sensors 32 and humidity sensors 32 are installed in the overburden layer 3 below the through holes on the reinforcement layer 5 to ensure that these sensors 32 are correctly placed so as to monitor the slope status in real time.

[0078] Step 6: Laying the surface material

[0079] On the surface of the reinforcement layer 5, a crushed stone layer 6, a sand layer 7 and a soil layer 8 are laid from bottom to top. Each layer of material should be evenly distributed and fully compacted to form a good filtering and supporting effect. Specifically, the thickness of the crushed stone layer 6 is 30 cm, the thickness of the sand layer 7 is 20 cm, and the thickness of the soil layer 8 is 30 cm. Ensure that the thickness of each layer of material is consistent to avoid uneven thickness, which affects the stability and function of the overall structure.

[0080] Step 7: Planting Landscape Vegetation

[0081] Finally, select local plant species with strong adaptability and drought and flood resistance on the surface of the top soil layer 8 to plant landscape vegetation. These plants not only beautify the environment, but also promote the ecological restoration process. When planting, attention should be paid to the spacing and layout between plants to ensure that they have enough growth space, and the irrigation system should be reasonably arranged according to the characteristics of the plants to promote the healthy growth of plants. It is recommended to set up temporary shading facilities in the early stage of planting to reduce the impact of direct sunlight on newly planted plants, and regularly perform maintenance and management to ensure the healthy growth of plants.
