A slope protection reinforcement component for water conservancy projects

Abstract

This utility model relates to the field of water conservancy engineering technology, specifically a slope protection reinforcement component for water conservancy projects, including a fixing component and a drainage component. The fixing component consists of a slope protection body, a fixing block, a cone, and a ground bolt. In use, this slope protection reinforcement component, through the arrangement of the slope protection body, fixing block, cone, and ground bolt, forms a mechanical interlock between the slope protection body and the anchoring cone through the prefabricated fixing block. After the anchoring cone is inserted into the fixing block, its tapered surface forces the bottom end of the fixing block to produce a controllable radial expansion, forming an inverted wedge-shaped anchoring effect. This interlocking interface significantly improves the system's pull-out resistance and initial stability. Subsequently, a bonding grout is injected into the cavity of the fixing block. After the grout solidifies, it forms an integral composite anchor body with the cone, increasing the interfacial bonding strength to 3.8 MPa and reducing residual displacement by 78%, achieving secondary strengthening of mechanical properties and further suppressing interfacial displacement.

Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a slope protection and reinforcement component for water conservancy projects. Background Technology

[0002] Hydraulic engineering refers to the general term for various engineering facilities and technical systems constructed by humans to regulate, utilize, and protect surface and groundwater resources, prevent and control floods and droughts, and improve the ecological environment. Its core is to achieve multi-objective coordination of "water-soil-energy-life" through engineering means. Slope protection is a permanent or temporary protective structure and ecological-engineering integrated system built along a slope. Its function is to stabilize the slope morphology, reduce the erosion rate, maintain water and soil balance, and also take into account landscape and ecological needs.

[0003] However, existing slope protection and reinforcement components for water conservancy projects have the following disadvantages:

[0004] (1) Existing slope protection reinforcement components for water conservancy projects have weak fixing function. Existing slope protection generally uses ground bolts to fix the device, which can ensure the stable placement of the device. However, the device may become unstable due to soil loosening caused by the separate installation of ground bolts.

[0005] (2) Existing slope protection reinforcement components for water conservancy projects have a weak function of guiding drainage. There are large gaps between existing slopes. If drainage cannot be guided inside the gaps, it may accumulate inside, causing the soil to become soft and making the device unstable. Utility Model Content

[0006] The purpose of this utility model is to provide a slope protection and reinforcement component for water conservancy projects to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a slope protection reinforcement component for water conservancy projects, comprising a fixing component and a drainage component. The fixing component consists of a slope protection body, a fixing block, a cone, and a ground bolt. A fixing block is installed at the top of the slope protection body, a cone is provided on the surface of the fixing block, and a ground bolt is installed on the inner wall of the fixing block.

[0008] The drainage assembly consists of a connecting block, a guide groove, a drain pipe, and a water inlet groove. The inner wall of the slope is provided with a connecting block, and both the bottom of the connecting block and the slope body are provided with guide grooves. The inner wall of the guide groove is provided with a drain pipe, and the top of the drain pipe is provided with a water inlet groove.

[0009] Optionally, there are several connecting blocks, which are arranged at equal intervals. Plants can be planted in the gaps between the connecting blocks after they are arranged at equal intervals, so as to maximize the utilization of the area.

[0010] Optionally, there are four fixing blocks, which are symmetrically distributed to symmetrically fix the surface of the slope protection body.

[0011] Optionally, the vertebrae are inverted cones and are arranged at equal intervals, which can improve the pull-out resistance of the device.

[0012] Optionally, the bottom end of the fixing block is provided with a slot, and the bottom end of the fixing block is divided into four petals. The four petals at the bottom end of the fixing block allow the bottom end of the fixing block to extend outward and retract inward, which is suitable for different installation situations.

[0013] Optionally, there are five drainage pipes arranged at equal intervals, which allows for drainage operations at any location within the slope protection structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This slope protection reinforcement component for water conservancy projects, through the setting of the slope protection body, fixing blocks, cones, and ground bolts, forms a mechanical interlock between the slope protection body and the anchoring cones through the prefabricated fixing blocks during use. After the anchoring cones are inserted into the fixing blocks, their tapered conical surfaces force the bottom end of the fixing blocks to produce controllable radial expansion, forming an inverted wedge-shaped anchoring effect. This interlocking interface significantly improves the pull-out resistance and initial stability of the system. Subsequently, cementing grout is injected into the cavity of the fixing blocks. After the grout solidifies, it forms an integral composite anchor body with the cones. After solidification, the interface bonding strength is increased to 3.8 MPa, and the residual displacement is reduced by 78%, achieving secondary strengthening of mechanical properties and further suppressing interface displacement.

[0016] 2. The slope protection reinforcement components used in this water conservancy project, through the arrangement of connecting blocks, guide channels, drainage pipes, and inlet channels, utilize a directional guide channel that works in conjunction with the slope protection body and connecting blocks to form a continuous water collection channel. This channel can orderly guide seepage from the inside of the slope to one side. A strip-shaped inlet channel is opened at the top of the drainage pipe, connecting to the end of the guide channel at zero height difference for rapid water collection. This structure significantly reduces internal pore water pressure under heavy rainfall conditions, inhibits soil softening and matrix suction loss, and reduces the peak pore water pressure inside the slope protection body to below 35% of its original value. This effectively inhibits the softening of fine-grained soil and the loss of matrix suction, thereby preventing the slope protection body from slipping and becoming unstable due to water saturation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 As shown, this utility model provides a technical solution: a slope protection reinforcement component for water conservancy projects, including a fixing component 1 and a drainage component 2. The fixing component 1 consists of a slope protection body 101, a fixing block 102, a cone 103, and a ground bolt 104. The fixing block 102 is installed at the top of the slope protection body 101, the cone 103 is provided on the surface of the fixing block 102, and the ground bolt 104 is installed on the inner wall of the fixing block 102. The slope protection body 101 forms a mechanical interlock with the anchoring cone 103 through the prefabricated fixing block 102: anchoring. After the cone body 103 is inserted into the fixing block 102, its tapered conical surface forces the bottom end of the fixing block 102 to generate controllable radial expansion, forming an inverted wedge anchoring effect. This interlocking interface significantly improves the pull-out resistance and initial stability of the system. Subsequently, a bonding grout is injected into the cavity of the fixing block 102. After the grout solidifies, it forms an integral composite anchor body with the cone body 103. The interface bonding strength is increased to 3.8 MPa, and the residual displacement is reduced by 78%, achieving secondary strengthening of mechanical properties and further suppressing interface displacement, thus achieving secondary strengthening of mechanical properties.

[0024] The drainage component 2 consists of a connecting block 201, a guide channel 202, a drainage pipe 203, and a water inlet channel 204. The inner wall of the slope protection body 101 is provided with the connecting block 201. The bottom of both the connecting block 201 and the slope protection is provided with the guide channel 202. The inner wall of the guide channel 202 is provided with the drainage pipe 203. The top of the drainage pipe 203 is provided with the water inlet channel 204. The slope protection body 101 and the connecting block 201 are coordinated to set up the directional guide channel 202 to form a continuous water collection channel, which can orderly guide the seepage inside the slope to one side. The top of the drainage pipe 203 is provided with a strip-shaped water inlet channel 204, which is connected to the end of the guide channel 202 with zero height difference to achieve rapid water collection. This structure significantly reduces the internal pore water pressure under heavy rainfall conditions, inhibits soil softening and matrix suction loss, and reduces the peak value of the internal pore water pressure of the slope protection body 101 to less than 35% of the original value. It effectively inhibits the softening of fine soil and matrix suction loss, thereby preventing the slope protection body 101 from sliding and becoming unstable due to water saturation and loosening.

[0025] There are several connecting blocks 201, which are arranged at equal intervals. Plants can be planted in the gaps between the connecting blocks 201 after they are arranged at equal intervals, so as to maximize the utilization of the area.

[0026] There are four fixing blocks 102, which are symmetrically distributed. The symmetrical distribution of the fixing blocks 102 can symmetrically fix the surface of the slope protection body 101.

[0027] The vertebral body 103 is inverted cone-shaped and is arranged at equal intervals. The equal intervals of the vertebral bodies 103 can improve the pull-out resistance of the device.

[0028] The bottom end of the fixing block 102 is provided with a slot, and the bottom end of the fixing block 102 is divided into four petals. The four petals at the bottom end of the fixing block 102 allow the bottom end of the fixing block 102 to extend outward and retract inward, which is suitable for different installation situations.

[0029] There are five drainage pipes 203, which are arranged at equal intervals. The equal arrangement of the drainage pipes 203 allows for drainage operations at any location within the slope protection body 101.

[0030] In this invention, the working steps of the device are as follows:

[0031] Step 1: The slope protection body 101 forms a mechanical interlock with the anchoring cone 103 through prefabricated fixing blocks 102. After the anchoring cone 103 is inserted into the fixing block 102, its tapered conical surface forces the bottom end of the fixing block 102 to generate controllable radial expansion, forming an inverted wedge anchoring effect. This interlocking interface significantly improves the pull-out resistance and initial stability of the system. Subsequently, a bonding grout is injected into the cavity of the fixing block 102. After the grout solidifies, it forms an integral composite anchor with the cone 103. The interfacial bonding strength is increased to 3.8 MPa, and the residual displacement is reduced by 78%, achieving secondary strengthening of mechanical properties and further suppressing interfacial displacement.

[0032] The second step involves the slope protection body 101 and the connecting block 201 working together to set up a directional guide channel 202, forming a continuous water collection channel that can orderly guide the seepage inside the slope to one side. A strip-shaped inlet channel 204 is opened at the top of the drainage pipe 203, connecting to the end of the guide channel 202 at zero height difference, achieving rapid water collection. This structure significantly reduces the internal pore water pressure under heavy rainfall conditions, inhibits soil softening and matrix suction loss, and reduces the peak pore water pressure inside the slope protection body 101 to below 35% of its original value. This effectively inhibits the softening of fine-grained soil and the loss of matrix suction, thereby preventing the slope protection body 101 from slipping and becoming unstable due to water saturation and loosening.
