Description

Technical Field

[0001] This invention belongs to the field of anchoring system technology, and specifically discloses a water-mechanical-biological coordinated anchoring system and a method for determining the additional anchoring force. Background Technology

[0002] In traditional slope and tunnel reinforcement engineering designs, drainage, mechanical anchoring, and ecological greening measures are often implemented as independent modules, lacking systematic and coordinated consideration. Drainage measures typically employ drainage pipes, serving only the single function of groundwater drainage. Over long-term use, these pipes are prone to blockage and failure due to siltation, failing to sustainably guarantee the stability of the reinforcement system. Mechanical anchoring measures generally use grouting anchors (cables), but the grout can easily block normal groundwater infiltration, leading to localized water pressure buildup in the reinforced area. Ecological greening measures often use surface planting, but plant roots cannot penetrate the reinforced anchoring area, resulting in ecological protection remaining merely superficial and failing to effectively supplement the mechanical anchoring performance. The ecological function contributes almost nothing to the mechanical reinforcement.

[0003] Currently, research in related fields is mostly focused on optimizing the function of a single measure, or simply achieving the physical superposition of "structural reinforcement + vegetation greening". It has failed to build an integrated technical system that achieves endogenous synergy and multiplied efficiency among the three from the perspective of technical principles. Ultimately, this has led to prominent contradictions in which the three core functions of "water, power, and life" are mutually isolated and even mutually restrictive, making it difficult to meet the comprehensive needs of "safety, efficiency, and ecology" for slope and tunnel reinforcement projects in the new era.

[0004] In line with the requirements of ecological civilization construction and green engineering development, and to solve the aforementioned problem of functional separation, the development of a synergistic integrated technology that takes into account drainage, mechanical anchoring and ecological protection has become an inevitable trend to promote the high-quality development of slope and tunnel reinforcement projects. It is also a key path to practice the concept of green development and achieve a win-win situation for engineering safety and ecological protection. Summary of the Invention

[0005] The purpose of this invention is to provide a water-mechanical-biological synergistic anchoring system to solve the technical problem that the functions of water, mechanical and biological elements are disconnected or even mutually restrictive in the existing technology, leading to the failure of the anchoring system.

[0006] A first aspect of the present invention provides a hydrodynamic-biological synergistic anchoring system, comprising a composite main rod section and an anchoring section disposed at one end of the composite main rod section;

[0007] The anchoring section includes a ballast chamber, a radial anchoring device, and an axial anchoring device installed within the radial anchoring device;

[0008] The ballast chamber is embedded in the composite main rod section and is used to extend into the radial anchoring device under the action of the groundwater inside, generating radial thrust on the radial anchoring device and axial thrust on the axial anchoring device at the same time, so that the axial anchoring device extends out of the radial anchoring device.

[0009] The composite main pole section includes a pole body and a vegetative nourishing device fixedly connected around the outer periphery of the pole body. The vegetative nourishing device contains pre-stored seeds and culture medium.

[0010] Preferably, the axial anchoring device includes a thruster and an axial anchoring component;

[0011] One end of the thruster is connected to the axial anchoring member, and the other end is connected to the ballast chamber.

[0012] Preferably, the thruster is wedge-shaped, and the tip of the wedge is connected to the axial anchor.

[0013] Preferably, the ballast chamber includes a chamber body, a one-way water inlet control component, and a one-way water outlet control component;

[0014] The one-way water inlet control device is installed on the cabin body and is activated when the difference between the water pressure of the external groundwater and the water pressure of the cabin body is greater than a first threshold.

[0015] The one-way water outlet control component is installed on the cabin and is activated when the difference between the water pressure in the cabin and the water pressure of the external groundwater is greater than a second threshold.

[0016] Preferably, the anchoring section further includes a permeable pipe;

[0017] One end of the permeable pipe is connected to the one-way water outlet control component, and the other end extends out of the surrounding rock via the composite main rod section.

[0018] Preferably, it also includes an integrated anchor head, which is disposed at one end of the composite main rod section extending out of the surrounding rock;

[0019] The integrated anchor head includes a support platform and a water storage and seepage cavity;

[0020] The support platform is fixed to the surrounding rock;

[0021] The water storage and seepage irrigation cavity is located inside the support platform and is connected to the vegetation nourishment device.

[0022] Preferably, the integrated anchor head further includes a plant growth pot;

[0023] The plant growth pot is embedded in the support platform and is connected to the plant growth and nourishment device.

[0024] A second aspect of the present invention provides a method for determining the additional anchoring force based on the above-described hydro-mechanical-biological synergistic anchoring system, comprising:

[0025] Step 1: Determine the additional axial anchoring force of the axial anchoring device based on the pressure of the groundwater in the pressure chamber, the water pressure loss coefficient, and the mechanical amplification coefficient of the thruster;

[0026] Step 2: Obtain the inner surface area of ​​the radial anchoring device and determine the water pressure transmission efficiency of the radial anchoring device;

[0027] Step 3: Determine the additional radial anchoring force of the radial anchoring device based on the inner surface area, the water pressure transmission efficiency, and the pressure of groundwater in the pressure chamber.

[0028] Preferably, after step 3, the method further includes:

[0029] Step 4: Determine the additional anchoring force of the vegetation;

[0030] Step 5: Determine the additional anchoring force of the hydro-mechanical-biological synergistic anchoring system based on the sum of the additional axial anchoring force, the additional radial anchoring force, and the additional plant anchoring force.

[0031] Preferably, step 4 specifically includes:

[0032] The additional plant anchoring force is determined based on the average tensile strength of the plant roots, the cross-sectional area of ​​the effective reinforcement zone of the plant roots, and the growth rate coefficient of the plant roots.

[0033] The hydrodynamic-biological synergistic anchoring system and the method for determining the additional anchoring force of the present invention have the following advantages compared with the prior art:

[0034] 1) Water Hazard Resource Utilization: Traditional thinking treats groundwater as a purely harmful factor, only "draining" or "blocking" it. This invention turns harm into benefit by proposing an innovative concept that automatically converts dynamic surrounding rock water pressure into anchoring force in real time through a built-in mechanical structure, achieving an adaptive response of "the more water, the more stable".

[0035] 2) Root System Engineering: The root systems of conventional ecological slope protection or tunnel revegetation are random and shallow, failing to provide reliable deep anchoring force. This invention proposes a vegetation nourishment device that provides protected deep growth channels and water supply for the root system, guiding and cultivating the randomly growing roots into predictable "biological anchors (cables)," actively guiding and utilizing the mechanical properties of the deep root system to enhance the engineering value of ecological measures.

[0036] 3) Dynamic Stabilization: The performance of conventional anchor bolts (cables) may decline over time, while plant growth enhances performance in the long term but provides no mechanical assistance to the system initially. This invention establishes a mathematical model of the dynamic evolution of anchoring force over time and with surrounding rock water pressure, elevating safety factor analysis from static to dynamic. This achieves seamless temporal integration and deep spatial fusion of the two mechanisms, enabling real-time assessment and prediction of long-term stable states and ensuring the safety and stability of anchoring measures throughout their entire lifecycle.

Detailed Implementation

[0048] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0049] A first aspect of the present invention provides a hydrodynamic-biological synergistic anchoring system, such as... Figures 1 to 10 It includes a composite main rod section and an anchoring section located at one end of the composite main rod section.

[0050] In this embodiment of the invention, the anchoring section is located at the foremost end of the anchoring system and embedded within a stable stratum, providing instantaneous dynamic anchoring force. The anchoring section includes a ballast chamber 1, a radial anchoring device 2, and an axial anchoring device disposed within the radial anchoring device 2. The structure of the anchoring section automatically converts water pressure into anchoring power, significantly enhancing the resistance at the anchoring interface and achieving instantaneous reinforcement that adapts to changing working conditions.

[0051] The aforementioned ballast chamber 1 is embedded in the composite main rod section and is used to extend into the radial anchoring device 2 under the action of the groundwater inside, generating radial thrust on the radial anchoring device 2 and axial thrust on the axial anchoring device at the same time, so that the axial anchoring device extends out of the radial anchoring device 2.

[0052] Exemplarily, the pressure chamber 1 of this embodiment includes a chamber body, a one-way water inlet control component 7, and a one-way water outlet control component 8. The chamber body is a closed chamber made of highly elastic composite material; the one-way water inlet control component 7 is disposed on the chamber body, specifically at the upper part of the chamber body, and opens when the difference between the water pressure of the external groundwater and the water pressure of the chamber body is greater than a first threshold, allowing external groundwater to enter the chamber body; the one-way water outlet control component 8 is disposed on the chamber body, specifically at the lower part of the chamber body, and opens when the difference between the water pressure of the chamber body and the water pressure of the external groundwater is greater than a second threshold, allowing groundwater to flow out of the chamber body. The one-way water inlet control component 7 and the one-way water outlet control component 8 of this embodiment can be automatically activated by the internal and external water pressure difference. The aforementioned first threshold and second threshold are determined by combining the external surrounding rock water and ground stress, and considering a certain small water volume to increase pressure.

[0053] The radial anchoring device 2 in this embodiment of the invention is a corrosion-resistant metal hollow thin-walled cylinder. Its sidewalls and ends can expand radially under the pressure generated by the pressure chamber 1, thereby providing radial anchoring. In order to lead external groundwater to the one-way water inlet control component 7, the outer wall of the radial anchoring component is defined to be regularly concave and convex, forming a water inlet channel 13 with one end outlet to the one-way water inlet control component 7.

[0054] The axial anchoring device of this invention includes a thruster 5 and an axial anchoring component 6; wherein the structure of the thruster 5 is as follows: Figure 3 As shown, one end of the thruster 5 is connected to the axial anchoring member 6, and the other end is connected to the ballast chamber 1. The thruster 5 is wedge-shaped, and the front end of the wedge is connected to the axial anchoring member 6. The axial anchoring member 6 can be a high-strength metal rod with anti-slip teeth or a high-strength hollow rod with built-in composite reinforcing agent, etc.

[0055] In this embodiment of the invention, the entire outer side of the anchoring section is wrapped with a permeable material to prevent soil from clogging the one-way water inlet control component 7. The permeable material can be non-woven fabric.

[0056] To avoid fatigue of the anchoring section caused by long-term high anchoring stress and splitting damage to the surrounding rock due to continuous compression, the anchoring section in this embodiment of the invention also includes a permeable pipe 9; one end of the permeable pipe 9 is connected to a one-way water outlet control component 8, and the other end extends out of the surrounding rock through the composite main rod section, thereby leading the groundwater in the pressure chamber 1 to the outside of the surrounding rock.

[0057] To enhance the value of ecological engineering measures, the composite main pole section of this invention includes a pole body 3 and a vegetation nourishing device 4 fixedly connected around the outer periphery of the pole body 3. The vegetation nourishing device 4 is pre-stored with seeds and culture medium.

[0058] The aforementioned pole 3 primarily bears the supporting force. For example, a high-strength, corrosion-resistant solid threaded pole can be used, with the external thread texture of the pole 3 enhancing plant climbing growth. A ballast chamber 1 is pre-installed at the end of the pole 3, and the pole 3 is securely connected to the ballast chamber 1 and the anchoring section. The aforementioned permeable pipe 9 is arranged at the bottom of the pole 3 near the surrounding rock. The section of the pole 3 containing the ballast chamber 1 is bonded to the surrounding rock using a highly permeable cementing material, while the remaining portion of the pole 3 is bonded to the surrounding rock using a slightly permeable cementing material.

[0059] The vegetative nourishment device 4 of this invention has good vertical water conductivity and root permeability, and can simultaneously transport water and guide loads, serving as a "directional runway" for the roots. A small amount of seepage water from the surrounding rock and water drained through the bottom permeable pipe 9 are absorbed by the vegetative nourishment device 4, nourishing the germination of internal seeds; the growing roots preferentially extend downwards along the moistened stem 3, being guided to the deep stable zone. The vegetative nourishment device 4 is fixed to the surrounding rock using a micro-permeable cementing material.

[0060] For example, to ensure that the vegetative growth device 4 does not affect the connection between the pole 3 and the surrounding rock, the vegetative growth device 4 and the pole 3 can be processed into an integral structure. The gap between the vegetative growth device 4 and the outer wall of the pole 3 serves as a plant growth space. Water-permeable holes are reserved on the outer surface of the vegetative growth device 4, and the entire structure is wrapped with a water-permeable non-woven fabric (to prevent soil from clogging the water-permeable pipe 9). A special lightweight culture medium composed of humus, water-retaining agent, and slow-release fertilizer, and the seeds of the target plant are pre-placed in the gap.

[0061] To achieve anchoring system locking, the water-mechanical-biological synergistic anchoring system of this embodiment further includes an integrated anchor head, which is disposed at the end of the composite main rod section extending out of the surrounding rock. The integrated anchor head includes a support platform 10 and a water storage and infiltration cavity 11. The support platform 10 is fixed to the surrounding rock and is a platform formed of steel or high-performance concrete, used for tensioning and locking the anchoring system. The water storage and infiltration cavity 11 is disposed within the support platform 10 and is connected to the vegetation nourishment device 4, used to collect surface runoff or receive supplementary irrigation, and slowly deliver water to the vegetation nourishment device 4 through capillary action. The integrated anchor head also includes a plant growth pot 12. The plant growth pot 12 is embedded in the support platform 10 and is connected to the vegetation nourishment device 4, used for later plant growth onto the surface to form surface ecological nodes. The integrated anchor head of this embodiment combines the functions of anchoring system locking and plant growth substrate.

[0062] The workflow of the water-mechanical-biological synergistic anchoring system in this embodiment of the invention is as follows: groundwater level rises (i.e., external groundwater pressure increases) → unidirectional water inlet control component 7 opens when the first threshold is met → external groundwater rushes into the chamber of ballast chamber 1 → the chamber extends axially and pushes thruster 5 to move axially → axial thrust is converted into axial anchoring component 6 pressure, and the radial pressure of the chamber is converted into radial anchoring component radial expansion force → anchoring → groundwater level drops (i.e., external groundwater pressure decreases) → unidirectional water outlet control component 8 opens when the second threshold is met → water flows into permeable pipe 9 → some water enters vegetation nourishment device 4, and some water is discharged to the surrounding rock → the radial pressure of ballast chamber 1 and the axial force of thruster 5 decrease, and the anchoring effect weakens.

[0063] A second aspect of the present invention provides a method for determining the additional anchoring force based on the above-described hydro-mechanical-biological synergistic anchoring system, comprising:

[0064] Step 1: Determine the additional axial anchoring force of the axial anchoring device based on the groundwater pressure in ballast chamber 1, the water pressure loss coefficient, and the mechanical amplification factor of thruster 5. As shown in formula (1):

[0065] (1)

[0066] In the formula, The additional axial anchoring force generated by the water pressure driving the thruster 5; The pressure loss coefficient is 0.85-0.95. The mechanical amplification factor (amplification factor) of the wedge-shaped thruster 5 is given. , , , These are the diameters of the two sides of the wedge-shaped structure. (for the height of the wedge structure). for Groundwater pressure at any given time (values ​​are taken from the "Code for Design of Hydraulic Structures SL744-2016"). The set start-up pressure threshold for thruster 5 (which is a structural characteristic of thruster 5). The effective area of ​​the axially increased anchor 6 is known (the structural design is known).

[0067] Step 2: Obtain the inner surface area of ​​the radial anchoring device 2 and determine the water pressure transmission efficiency of the radial anchoring device 2.

[0068] Step 3: Determine the additional radial anchoring force of the radial anchoring device 2 based on the inner surface area, water pressure transmission efficiency, and groundwater pressure in the ballast chamber 1, as shown in formula (2):

[0069] (2)

[0070] In the formula, Additional radial anchoring force for radial anchoring device 2; The hydraulic pressure transmission efficiency (depends on the compressibility of the material of the radial anchoring device 2). Let be the inner surface area of ​​the radial anchoring device 2 (the structural design is known).

[0071] Step 4: Determine the additional plant anchoring force. Specifically, determine the additional plant anchoring force based on the average tensile strength of the plant roots, the cross-sectional area of ​​the effective reinforcement zone of the plant roots, and the growth rate coefficient of the plant roots.

[0072] Root growth conforms to the Logistic regression model: plant growth follows a "slow-fast-slow" Logistic pattern. After seed germination, the root system is in the adaptation and initial development stage, with slow biomass accumulation and weak mechanical contribution. This corresponds to the formula (3) in which ( The slow growth phase within a given timeframe. Rapid growth phase: After the root system is established, under suitable conditions, it enters an exponential rapid growth phase, with a rapid increase in the biological potential anchoring force. This corresponds to the phase of rapid decay of the exponential term in the formula. Maturity saturation phase: Limited by genetic characteristics and environmental capacity, the root growth rate slows down and tends to stabilize, and biomass approaches its upper limit. This corresponds to the phase of rapid decay of the exponential term in the formula. (Approaching 0), its force can be expressed as:

[0073] (3)

[0074] In the formula, for The additional anchoring force of vegetation at any moment; The maximum root area ratio (root cross-sectional area / soil cross-sectional area) is determined by the plant variety and the capacity of the vegetation nourishment device 4. The average tensile strength of the plant root system; Cross-sectional area of ​​the effective reinforcement zone for the plant root system; This is the growth rate coefficient of the plant root system (determined by the plant species). The starting time for plant roots to begin making effective mechanical contributions (determined by plant species).

[0075] Step 5: Determine the additional anchoring force of the water-mechanical-biological synergistic anchoring system based on the sum of the additional axial anchoring force, the additional radial anchoring force, and the additional vegetation anchoring force.

[0076] Correspondingly, the anchoring force of the system throughout its entire lifecycle is: (quantifying the change in the total anchoring force of the system from the completion of construction to long-term operation.)

[0077] Total anchoring force of the system It consists of three parts: .

[0078] in The basic anchoring force is provided by the bonding force of the grout and the friction of the composite main rod section. It can be calculated according to the traditional anchor (cable) theory in relevant specifications such as the "Technical Specification for Rock and Soil Anchors and Shotcrete Support Engineering". It is constant after construction.

[0079] Adding anchoring force to dynamic water pressure: can be defined as a function of time. It depends on the real-time water pressure. This can be obtained through seepage monitoring or simulation.

[0080] Additional anchoring force for plants: This is the force provided by the plant root system as it grows and develops over time, and it depends on the variety of engineered seeds used.

[0081] This invention incorporates time-varying anchoring force into stability evaluation, enabling real-time safety warnings and performance predictions based on monitoring data. Taking a slope as an example, the dynamic safety factor analysis framework for slopes is as follows:

[0082] A simplified Bishop method is used for illustration. Consider a circular arc-shaped slip surface, where the safety factor is defined as the ratio of the resisting moment to the sliding moment. Without reinforcement, the resisting moment of the slope along a potential slip arc is... The sliding torque is After introducing the anchoring system of this invention, the incremental anti-slip moment it provides for:

[0083] (4)

[0084] in, The angle between the anchoring system and the tangential direction of the sliding surface. This is the lever arm of the anchoring system resistance about the sliding center.

[0085] Therefore, the dynamic safety factor after reinforcement is:

[0086] (5)

[0087] In the formula, This is the initial safety factor.

[0088] The hydro-mechanical-biological synergistic anchoring system and the method for determining the additional anchoring force of the present invention have the following beneficial effects:

[0089] 1) Water Hazard Resource Utilization: Traditional thinking treats groundwater as a purely harmful factor, only "draining" or "blocking" it. This invention turns harm into benefit by proposing an innovative concept that automatically converts dynamic surrounding rock water pressure into anchoring force in real time through a built-in mechanical structure, achieving an adaptive response of "the more water, the more stable".

[0090] 2) Root System Engineering: The root systems of conventional ecological slope protection or tunnel revetment grow randomly and superficially, failing to provide reliable deep anchoring force. This invention proposes a vegetation nourishment device 4, which provides protected deep growth channels and water supply for the root system, guiding and cultivating the randomly growing root system into predictable "biological anchors (cables)," actively guiding and utilizing the mechanical properties of the deep root system to enhance the engineering value of ecological measures.

[0091] 3) Dynamic Stabilization: The performance of conventional anchor bolts (cables) may decline over time, while plant growth enhances performance in the long term but provides no mechanical assistance to the system initially. This invention establishes a mathematical model of the dynamic evolution of anchoring force over time and with surrounding rock water pressure, elevating safety factor analysis from static to dynamic. This achieves seamless temporal integration and deep spatial fusion of the two mechanisms, enabling real-time assessment and prediction of long-term stable states and ensuring the safety and stability of anchoring measures throughout their entire lifecycle.
