Once the embankment landslides, it will pose a serious threat to the surrounding ecological environment, infrastructure, and people's lives and property safety.

[0003] Traditional methods of reinforcing embankments to prevent landslides have many limitations. For example, common reinforcement structures are difficult to effectively share the pressure on the embankment, resulting in a high risk of landslides under long-term stress.

DETAILED DESCRIPTION

[0033] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components to avoid unnecessary confusion of the concepts of the present invention.

[0034] See also Figure 1 , Figure 2 and Figure 3 , a levee anti-landslide reinforcement structure, when implementing the levee anti-landslide reinforcement project, the levee site must first be surveyed to determine the location of the levee area A and the stress area B. The levee area A is the part of the levee edge that directly bears the impact of water flow and soil pressure, and the stress area B is the rear area used to bear the tension wall 3 to share the pressure of the levee area A.

[0035] A suitable foundation pit is excavated in the stress area B. The depth and area of ​​the foundation pit should be determined according to the actual situation of the embankment and the design size of the tension wall 3. A formwork is set up in the foundation pit, and the steel bars are tied according to the design requirements, and then concrete is poured to form the tension wall 3. When pouring the tension wall 3, it is necessary to reserve several groups of holes at the top thereof so as to insert the positioning column 8 later. In addition, the U-shaped rod 9 is tied to the steel bars in the tension wall 3 so that part of the U-shaped rod 9 is leaked out. The concrete of the tension wall 3 should be vibrated and compacted to ensure its strength and stability. In addition, the indirection of the U-shaped rod 9 is set according to the spacing of the partition wall 2.

[0036] The tension wall 3 is made of reinforced concrete structure, and its strength and size are designed according to the actual stress conditions of the embankment. A positioning column 8 is inserted into the hole reserved at the top of the tension wall 3. The positioning column 8 is made of bamboo because bamboo has certain toughness and strength, is easy to obtain and has low cost. After the bamboo column is inserted into the hole, the positioning column 8 is firmly fixed to the tension wall 3 by filling the hole with fixing materials such as cement mortar, thereby fixing the tension wall 3 in the soil layer to prevent the tension wall 3 from displacement.

[0037] The partition wall 2 is laid in the embankment area A according to the designed spacing and position. The partition wall 2 is L-shaped and laid with the right angle facing inward. This design can better prevent the lateral displacement of the soil and enhance the stability of the embankment. When laying the partition wall 2, it is necessary to ensure that the steel bars reserved on its outer side can be smoothly implanted into the subsequent pouring of the protective wall 1, so that the protective wall 1 and the partition wall 2 form a whole and jointly withstand the soil pressure and water flow impact.

[0038] A hole is drilled through the preset hole on the partition wall 2 toward the embankment area A, and the depth and angle of the hole should meet the installation requirements of the tensioner 4. One end of the tensioner 4 is connected to the partition wall 2, and the other end is connected to the tension wall 3.

[0039] See also Figure 5 and Figure 6 , the tensioner 4 is composed of a U-shaped card 41, a fastener 42, a load-bearing rod 43 and a ball 44. The U-shaped card 41 is hinged to the U-shaped rod 9 on the tension wall 3 by bolts to realize the connection between the tensioner 4 and the tension wall 3. The stud 421 of the fastener 42 is inserted from the bottom of the U-shaped card 41, and the fixed column 422 installed on the top thereof contacts the U-shaped card 41 through the bearing frame 423, so that the stud 421 can be rotated more smoothly. A fastening nut 424 is provided on the stud 421, and the stud 421 can be locked by rotating the fastening nut 424 to prevent it from loosening. An adjusting nut 425 is installed at the other end of the stud 421, and the threaded end of the load-bearing rod 43 is threadedly connected to the stud 421. When the tension needs to be adjusted, the adjusting nut 425 can be rotated to make the load-bearing rod 43 expand and contract, thereby changing the tension on the partition wall 2. The ball 44 installed at one end of the load-bearing rod 43 can be flexibly rotated in the circular groove hole 10 after being inserted into the circular groove hole 10 of the partition wall 2, ensuring that the direction of the pulling force is always consistent with the force direction of the partition wall 2.

[0040] When the load-bearing rod 43 is fastened, the fastening nut 424 can be pressed against the bottom end of the U-shaped clip 41 by the fastening nut 424 to lock the fastener 42 and prevent it from rotating or moving.

[0041] The load-bearing rod 43 can be a steel wire rope, and the other end of the steel wire rope needs to be connected to a threaded cylinder, so that it is convenient to connect with the fastener 42. In this way, the steel wire rope has flexibility. When the U-shaped rod 9 and the circular groove hole 10 cannot be aligned, they can be connected by a steel wire rope to facilitate the installation of the tensioner 4. After the tensioner 4 is installed, the load-bearing rod 43 needs to be adjusted to make it taut.

[0042] Specifically, the U-shaped card 41 is hinged to the U-shaped rod 9 inserted into the top and side of the tension wall 3 through bolts, and the load-bearing rod 43 is inserted into the circular groove hole 10 on the partition wall 2, so that the ball 44 is located in the circular groove hole 10, thereby achieving the inward application of tension to the partition wall 2. During the installation process, the tension and tightening degree of the tensioner 4 can be adjusted by adjusting the fastener 42. In addition, the circular groove hole 10 on the partition wall 2 is an inlaid metal ring, so the ball 44 can be adjusted in direction in the metal ring, and the metal ring is also connected to the built-in steel bar of the partition wall 2, so that when the metal ring is stressed, the partition wall 2 is evenly stressed.

[0043] See also Figure 7 , insert the supporting wall 5 at the designed position of the protective wall 1. The supporting wall 5 is composed of several groups of columns 51. The upper end of the column 51 is a fork design. The waterproof cloth 52 is laid in the fork groove at the upper end of the column 51, and then the column 51 is inserted into the soil layer on the edge of the embankment. When inserting, the verticality and depth of the column 51 must be ensured to ensure the waterproof and supporting effects. Reinforcement is reserved on the upper end surface of the column 51 so as to connect with the protective wall 1 to be poured later, so that the waterproof cloth 52 can be introduced into the protective wall 1 to play a waterproof role.

[0044] The column 51 of the supporting wall 5 is made of solid materials, such as precast concrete columns or steel pipe columns. The depth of the column 51 inserted into the soil layer should be determined according to factors such as the geological conditions of the embankment and the height of the protective wall 1. Generally, sufficient anchoring depth should be ensured to provide stable support. The waterproof cloth 52 is made of materials with good waterproof performance and strong durability, such as geomembrane. After the waterproof cloth 52 is laid in the fork groove at the upper end of the column 51, it is fixed by tying or bonding to ensure that the waterproof cloth 52 will not be displaced during the pouring of the protective wall 1. After the steel bars reserved on the upper end surface of the column 51 are connected to the steel bars of the protective wall 1, when the protective wall 1 is poured, the concrete tightly combines the column 51 with the protective wall 1, which not only enhances the stability of the protective wall 1, but also effectively introduces the waterproof cloth 52 into the protective wall 1, plays a role in preventing groundwater infiltration and protecting the bottom of the protective wall 1 from water erosion.

[0045] Finally, after the partition wall 2 and the supporting wall 5 are installed, the formwork of the protective wall 1 is set up, the steel bars are tied, the protective wall 1 and the steel bars of the partition wall 2 are connected as a whole, and then concrete is poured to form the protective wall 1. The protective wall 1 should be poured evenly to ensure its strength and integrity so that it can effectively block the impact of water flow and soil.

[0046] See also Figure 4 On the inner side of each partition wall 2, several groups of pressure sensors 6 are installed according to the designed position, and the pressure sensors 6 are embedded in the slots on the inner side of the partition wall 2 and connected to external data acquisition and analysis equipment through wires to monitor the pressure changes of the soil on the partition wall 2 in real time.

[0047] The A pipe 71 and the B pipe 72 of the optical fiber detection group 7 are made of corrosion-resistant and pressure-resistant materials, such as PVC pipes. The A pipe 71 and the B pipe 72 are laid on the top and inner side of multiple partition walls 2 respectively for importing and exporting optical fibers. Two connecting columns 73 distributed up and down are installed on each partition wall 2, and the connecting columns 73 are made of insulating and sturdy materials, such as plastic columns. The two ends of the optical fiber are respectively introduced into the A pipe 71 and the B pipe 72 from the ends of the connecting columns 73, and the optical fibers in the A pipe 71 and the B pipe 72 are connected to the monitoring system through optical fiber sensors. When the soil moves, the exposed optical fibers between the connecting columns 73 will be squeezed or stretched, causing the shape of the optical fiber to change. The optical fiber sensor can detect this shape change and transmit the signal to the monitoring system, thereby realizing real-time monitoring of soil movement.

[0048] The optical fibers in the two connecting posts 73 store longer optical fibers, so that during soil movement, the optical fibers led out between the connecting posts 73 will be compressed, and the optical fibers will be squeezed by the soil and move backwards, changing their shape according to the movement of the soil. The optical fiber will be subjected to strain such as stretching, compression or bending. According to the strain sensing principle of the optical fiber, the refractive index of the optical fiber will change, which will cause the characteristics of light propagation in the optical fiber, such as the phase, wavelength, and intensity of the light, to change. By detecting the changes in these optical characteristics through the optical fiber sensor, the strain condition of the optical fiber can be inferred, thereby knowing the movement of the soil.

[0049] A method for protecting embankment from landslides, the specific operation is as follows:

[0050] S1: Pressure sharing and increased tolerance

[0051] When the embankment is subjected to soil pressure, the soil pressure is first applied to the partition wall 2. The partition wall 2 transfers the pressure to the tension wall 3 through the tensioner 4. Since the tension wall 3 is buried in the soil, the friction and anchoring force between it and the soil can share the pressure of the partition wall 2, thereby enhancing the bearing capacity of the partition wall 2 and effectively preventing the embankment from sliding.

[0052] S2: Bottom protection and stability enhancement of the protective wall

[0053] After the column 51 of the supporting wall 5 is inserted into the soil layer, the waterproof cloth 52 at the upper end thereof is introduced into the protective wall 1 to form a waterproof layer, thereby preventing groundwater from penetrating from the bottom of the protective wall 1 and protecting the bottom of the protective wall 1. At the same time, the column 51 is connected to the protective wall 1 to provide additional support for the protective wall 1 and enhance the stability of the protective wall 1.

[0054] S3: Real-time monitoring and protection

[0055] During the daily operation of the embankment, the pressure sensor 6 on the partition wall 2 detects the pressure change of the soil in real time and transmits the data to the data acquisition and analysis equipment. The optical fiber detection group 7 monitors the soil movement in front of each partition wall 2 in real time by detecting the change of the optical fiber shape. Once the pressure or soil movement is abnormal, an alarm is issued in time so that corresponding protective measures can be taken, such as reinforcing the embankment, adjusting the tension of the tensioner 4, etc., to ensure the safety and stability of the embankment.

[0056] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims.
