Description

Technical Field

[0001] This invention relates to the field of road engineering quality testing, and in particular to a high embankment slope structure and its deformation monitoring device. Background Technology

[0002] High embankment slopes refer to slopes formed by embankments with a roadbed fill slope height greater than 20m. Due to their large height, heavy weight, and high stability requirements, they require special design and protection.

[0003] Slope protection structures typically employ methods such as turfing, stone masonry, and arched frameworks to prevent landslides and ensure road safety. Chinese patent application number 202010363685.1 discloses a stabilizing structure for a high embankment slope, comprising: a retaining wall, steel pipe piles, and anchor bolts; a retaining wall is set at the toe of the high embankment slope, and steel pipe concrete piles are set on the inner surface of the retaining wall; an excavation step and a gravel drainage strip are set at the cut-fill interface; the bottom of the steel pipe concrete piles and the steel pipe piles pass through the gravel drainage strip; the upper section of the steel pipe piles is fitted with a grouting sleeve, the lower end of the grouting sleeve extends to the gravel drainage strip, and the upper end is connected to the grouting port through a grouting pipe; a fixed pulley and pipeline channel are set inside the steel pipe concrete piles; the anchor bolts are fixed in the rock strata after the excavation step, and the exposed part at the top is connected to steel strands; the steel strands are connected to the fixed pulleys or steel pipe piles at the same height; the steel strands connected to the fixed pulleys are led out through the pipeline channel to the capping beam and connected to the steel strand tensioning device. This invention is applicable to the reinforcement and active control of embankment deformation during construction and operation, and is particularly suitable for embankment projects with high requirements for embankment stability and subsequent operational safety. The technical solution proposed in this invention reinforces high embankment slopes through structural improvements; however, in practical use, its complex structure and difficult construction, coupled with its reliance on external reinforcement structures, can easily lead to high load-bearing capacity and a short service life for the reinforced structure. Summary of the Invention

[0004] Therefore, in response to the above problems, this invention proposes a high embankment slope structure and its deformation monitoring device, which solves the technical problem that existing embankment slopes are prone to landslides due to climate changes such as rain, resulting in road collapse or deformation without timely monitoring and alarm.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high embankment slope structure, comprising an embankment slope body and an embankment reinforcement structure disposed on the embankment slope body. The embankment reinforcement structure includes mutually cooperating transverse support structures and vertical support structures. The transverse support structure includes a bottom transverse protective net and a top transverse protective net. The bottom transverse protective net is composed of several transverse telescopic support rods and a base plate support seat. Each transverse telescopic support rod is perpendicular to the base plate support seat, and each transverse telescopic support rod is movably connected to the base plate support seat. The base plate support is fixedly installed on the outer edge of the embankment slope body. Each of the transverse telescopic support rods is inserted into the embankment slope body along the horizontal plane. A first positioning hole is provided around the outer circumferential side of the transverse telescopic support rod. The vertical support structure includes several vertical support rods and anti-tilting baffles provided on the outer circumferential side of the vertical support rods. Each of the vertical support rods is perpendicular to the horizontal plane. Each of the vertical support rods is fixedly connected to the transverse telescopic support rod through the first positioning hole. The top transverse protective net is covered on the top of the vertical support rod.

[0006] Furthermore, each of the transverse telescopic support rods is provided with a rotating drill bit at its free end, and each of the transverse telescopic support rods can extend and retract along its own axis.

[0007] Furthermore, a connecting sleeve is provided on the outer circumferential side of the vertical support rod, the connecting sleeve rotates along the axial direction of the vertical support rod, and the anti-tilt baffle is fixedly installed on the connecting sleeve.

[0008] Furthermore, an arc-shaped connecting groove or connecting protrusion is provided on the end of the anti-tilt baffle away from the vertical support rod. The anti-tilt baffles are respectively provided on the left and right sides of the vertical support rod. The anti-tilt baffle on one side is provided with a connecting groove, and the anti-tilt baffle on the other side is provided with a connecting protrusion. The connecting grooves and connecting protrusions on two adjacent vertical support rods cooperate with each other to connect the two adjacent vertical support rods.

[0009] Furthermore, the base plate support has a structure that is narrower at the top and wider at the bottom, the vertical cross-section of the base plate support is a right trapezoid, a functional chamber is provided inside the base plate support, and the transverse telescopic support rod is disposed in the functional chamber.

[0010] Furthermore, a ground-fixed anchor is provided inside the base plate support. The ground-fixed anchor is located on the bottom surface of the base plate support and extends upward into the functional cavity. During operation, the ground-fixed anchor is inserted into the geological layer to provide fixation for the base plate support.

[0011] Furthermore, a locking mechanism is provided on the base plate support seat within the functional cavity. The locking mechanism includes a motorized rotating shaft and a locking protrusion disposed on the outer circumferential side of the motorized rotating shaft. The locking protrusion completely covers the motorized rotating shaft. The vertical cross-section of the locking protrusion is an egg-shaped structure that is narrow at one end and wide at the other. The motorized rotating shaft is arranged along the length direction of the functional cavity. The transverse telescopic support rod and the ground fixed anchor are both abutted against the locking protrusion. The motorized rotating shaft rotates along its own axis by external force.

[0012] Furthermore, the motor shaft extends outward to protrude from the functional chamber. A force-applying locking end is provided on one end of the motor shaft that protrudes from the functional chamber. The force-applying locking end includes a support portion and a force-applying portion that are fixedly connected. The support portion is fixedly disposed on the central axis of the motor shaft. The force-applying portion is disposed around the support portion and perpendicular to the central axis of the motor shaft. The force-applying portion includes a fixed end and a freely extending end. There are three force-applying portions, and the circumferential angle between two adjacent force-applying portions is 120°.

[0013] Furthermore, the fixed end and the free extension end are of the same length. The fixed end is provided with a receiving groove, and the free extension end is placed in the receiving groove. When the motor shaft rotates, the free extension end remains completely placed in the receiving groove. After the motor shaft completes rotation and tightening, the free extension end extends outward and abuts against the ground.

[0014] A deformation monitoring device is applied to a high embankment slope structure, comprising a monitoring rod that works in conjunction with a vertical support rod. A first buckle is provided at the top of the vertical support rod. Traction monitoring components are spaced apart on the monitoring rod. The traction monitoring components include a tension sensor and a second buckle that works in conjunction with the tension sensor. One end of the monitoring rod is fixedly disposed at the top of the embankment slope body and is placed inclined downward along the embankment slope body. The first buckle and the second buckle are fastened together.

[0015] By adopting the aforementioned technical solution, the beneficial effects of the present invention are: 1. This invention reinforces high embankment slopes by incorporating an embankment solidification structure. This structural intervention, combined with common greenbelt reinforcement methods, works synergistically to strengthen the slope, preventing landslides caused by rain and other climatic factors. In severe cases, this can lead to soil erosion at the roadbed, causing road collapse or deformation. The invention primarily utilizes a combination of transverse and longitudinal support structures. The transverse support structure provides stable support to the embankment slope soil from the bottom, preventing slippage. The vertical support structure provides vertical support to the soil as a whole, with a similar underlying principle. Reinforcing bars are driven into the soft soil to provide a skeletal protection, ensuring that landslides do not occur in the upper and surface layers of the soil. The lateral support structure mainly consists of a base plate support and lateral telescopic support rods. The base plate support serves as the main anti-slip base, and its structural improvements enable it to stably cooperate with the geological layer, thereby providing positioning support for the lateral telescopic support rods. The lateral telescopic support rods are inserted laterally into the soil, with one end connected to the base plate support and the other end extending into the soil until it reaches the hard geological layer. At this point, the base plate support and the lateral telescopic support rods together form a bottom anti-slip net for the soil, preventing slippage at the bottom of the soil.

[0016] 2. In the present invention, the vertical support structure works in conjunction with the horizontal support structure and relies on the horizontal support structure for support. The vertical support rods in the vertical support structure are inserted into the soil in a vertical direction and then fixed by being inserted into the first positioning hole of the horizontal telescopic support rod. The vertical support rods are equipped with anti-tilting baffles to increase the contact area with the soil and prevent the middle and upper soil layers from collapsing due to weather factors such as rain. Adjacent vertical support rods are connected by connecting grooves and connecting protrusions on the anti-tilting baffles, thus ensuring that each vertical support rod forms a wall on the vertical plane to protect the soil.

[0017] 3. This invention comprehensively reinforces the most basic base plate support. Ground-fixed anchors are installed on the base plate support, improving the stability of the connection between the base plate support and the ground from the bottom, ensuring a stable connection. Simultaneously, a functional chamber is provided within the base plate support, containing a locking mechanism. This locking mechanism simultaneously drives the movement of the ground-fixed anchors and the lateral telescopic support rods. Specifically, the ground-fixed anchors are in vertical contact with the soil, while the lateral telescopic support rods are in horizontal contact with the soil. Both are connected by abutting against the locking mechanism. The locking mechanism rotates via a motorized shaft, causing the locking protrusions above it to rotate as well. Due to the structure of the locking protrusions… Its unique feature is its egg-shaped structure, narrow at one end and wide at the other. This design ensures that as the motorized shaft rotates, the engagement between the locking protrusion and the lateral telescopic support rod and the ground-fixed anchor transitions from the narrow end to the wide end. This provides a thrust to both the lateral telescopic support rod and the ground-fixed anchor, allowing for a tighter fit with the soil. To ensure the stability of this thrust, the invention includes a force-applying locking end at the end of the motorized shaft. After the shaft rotates, the force-applying part on the locking end contacts and engages with the ground. Specifically, the free extension end of the force-applying part extends out and engages with the ground, and its triangular structure provides stability to the engagement.

[0018] 4. The deformation monitoring device proposed in this invention is used in conjunction with the embankment slope structure. Specifically, the monitoring rod in the deformation monitoring device is directly connected to the vertical support rod. One end of the rod is fixed to the top of the main body of the embankment slope, and the middle section is fixed by the vertical support rod. At the same time, a traction force monitoring component is set at the connection between the two to monitor the traction force at various points on the monitoring rod. When the embankment slips, the soil pushes the anti-tilt baffle, which in turn causes the vertical support rod to tilt. After the vertical support rod tilts, it will pull the monitoring rod through the buckle, causing the tension sensor to receive the signal and the tension value to change. By setting an alarm, an alarm will be triggered when the preset value is reached, thus completing the monitoring of the slope structure stability. Attached Figure Description
