Description

Technical Field

[0001] This utility model belongs to the field of civil engineering technology, specifically, it relates to a civil grid structure. Background Technology

[0002] In the field of civil engineering, geogrid structures are often used as core components for roadbed reinforcement, slope protection, and temporary access road construction. Their load-bearing stability, drainage efficiency, and anti-slip performance directly affect the quality of the project. However, existing geogrid structures generally suffer from the problem of not being able to balance load-bearing and anti-slip performance: traditional geogrids often use a single material and simple rib design, which are prone to bending and deformation when subjected to heavy equipment loads or long-term external forces. In addition, to ensure drainage, the surface of the geogrid is often designed with a smooth through-hole structure, which makes it easy for people or equipment to slip when moving in wet environments. This not only fails to meet the load-bearing requirements of high-load projects, but also poses significant safety hazards and is difficult to adapt to the comprehensive use requirements of complex civil engineering scenarios. Utility Model Content

[0003] The purpose of this invention is to provide a civil grid structure to solve the problems mentioned in the background art.

[0004] A civil engineering grid structure includes a grid plate, a grid frame, and longitudinal reinforcing ribs. The grid frame is rotatably connected to the inside of the grid plate. The grid plate is provided with reinforcing plates, through holes, metal protrusions, through holes, slots, and transverse reinforcing ribs. The longitudinal reinforcing ribs are engaged with the grid frame through the slots.

[0005] In a preferred embodiment of this utility model, the reinforcing plate is fixedly connected to the grating plate, and the reinforcing plate is made of high-strength alloy to improve the overall load-bearing capacity of the grating plate.

[0006] In a preferred embodiment of this utility model, the through holes one and two are arranged in an array on the grating plate, and the diameter of the through hole one is larger than that of the through hole two. The metal protrusions are evenly distributed on the upper surface of the grating plate, and the height of the metal protrusions is 3-5mm, so as to enhance the anti-slip performance of the grating plate surface.

[0007] In a preferred embodiment of the present invention, a base plate is fixedly connected to the bottom of the grid frame, a water collection trough is connected to the top of the base plate, and a water leakage hole penetrating the water collection trough and the base plate is provided at the bottom of the inner wall of the water collection trough.

[0008] In a preferred embodiment of this utility model, the bottom surface of the grid frame is provided with raised particles, and the lower surface of the base plate is provided with an anti-slip pad. The anti-slip pad is made of nitrile rubber and has a diamond-shaped anti-slip pattern.

[0009] In a preferred embodiment of this utility model, the transverse reinforcing ribs and the longitudinal reinforcing ribs are arranged perpendicularly to each other, and the cross-sections of the transverse reinforcing ribs and the longitudinal reinforcing ribs are both trapezoidal.

[0010] In a preferred embodiment of this utility model, the bottom of the water collection tank is inclined at an angle of 5-8°, and the lowest end of the water collection tank is connected to the drain hole to accelerate the drainage of water accumulated in the water collection tank.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. This civil engineering grating structure features an array of through holes of different diameters on the grating plate, which enables graded filtration of accumulated water, intercepts impurities of different particle sizes, prevents blockage of the through holes, and guides the accumulated water to flow quickly to the drainage holes for discharge, avoiding water accumulation inside the structure, reducing water corrosion of the grating structure, and extending the service life of the structure.

[0013] 2. In this civil engineering grating structure, the metal protrusions on the upper surface of the grating plate increase the friction of the contact surface, preventing personnel or equipment from slipping when moving on the surface. The nitrile rubber anti-slip pads on the lower surface of the base plate and the protruding particles on the bottom surface of the grating frame respectively enhance the adhesion between the grating structure and the mounting surface, and between the grating frame and the base plate, preventing overall structural displacement.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0024] Example 1:

[0025] like Figures 1 to 6 As shown, a civil engineering grid structure includes a grid plate 1, a grid frame 2, and longitudinal reinforcing ribs 3. The grid frame 2 is rotatably connected to the inside of the grid plate 1. The grid plate 1 is provided with a reinforcing plate 101, a first through hole 102, a metal protrusion 103, a second through hole 104, a slot 105, and a transverse reinforcing rib 106. The longitudinal reinforcing ribs 3 are engaged with the grid frame 2 through the slot 105.

[0026] The reinforcing plate 101 is fixedly connected to the grating plate 1, and the reinforcing plate 101 is made of high-strength alloy to improve the overall load-bearing capacity of the grating plate 1. Through holes 102 and 104 are arranged in an array on the grating plate 1, and the diameter of through hole 102 is larger than that of through hole 104. Metal protrusions 103 are evenly distributed on the upper surface of the grating plate 1, and the height of the metal protrusions 103 is 3-5mm to enhance the anti-slip performance of the surface of the grating plate 1. The transverse reinforcing ribs 106 and the longitudinal reinforcing ribs 3 are arranged perpendicularly to each other, and the cross-sections of the transverse reinforcing ribs 106 and the longitudinal reinforcing ribs 3 are trapezoidal.

[0027] Basic structure assembly:

[0028] The grating plate 1 is prefabricated with reinforcing plate 101, through hole 102, metal protrusion 103, through hole 2 104, slot 105, and transverse reinforcing rib 106. The reinforcing plate 101 is made of high-strength alloy material and is fixed to the grating plate 1 by welding. The welded joints need to be ground to ensure a smooth surface and improve the overall load-bearing capacity of the grating plate 1.

[0029] The grid frame 2 is rotatably connected to the reserved mounting groove inside the grid plate 1 via a rotating shaft structure. Lubricating oil is applied to the rotating connection to ensure that the grid frame 2 can rotate flexibly, which facilitates subsequent structural adjustment and maintenance.

[0030] Align the longitudinal reinforcing rib 3 with the slot 105 on the grating plate 1, and apply appropriate pressure to secure the longitudinal reinforcing rib 3 to the grating frame 2. The grating plate 1 is made of high-strength polyethylene with a thickness of 8-12mm and a width of 1000-1500mm.

[0031] The reinforcing plate 101 has a thickness of 5-8mm and a width of 100-150mm, and is evenly distributed along the length of the grating plate 1 with a spacing of 300-500mm. Through holes 102 have a diameter of 15-20mm, and through holes 104 have a diameter of 5-8mm. Both types of through holes are arranged in a matrix along the surface of the grating plate 1. The row and column spacing of the through hole 102 matrix is ​​50-80mm, and the row and column spacing of the through hole 104 matrix is ​​30-50mm. The transverse reinforcing rib 106 and the longitudinal reinforcing rib 3 have trapezoidal cross-sections with an upper base width of 10-15mm, a lower base width of 20-25mm, and a height of 15-20mm.

[0032] The rotating connection between the grating frame 2 and the grating plate 1 is made of stainless steel shaft with a diameter of 8-12mm and a length consistent with the width of the grating plate 1. Both ends of the shaft are connected to the reserved mounting slots of the grating plate 1 through bearings. The bearing model is deep groove ball bearing 6203.

[0033] The longitudinal reinforcing rib 3 is fixed to the grid frame 2 by snap-fitting. The depth of the snap-fit ​​groove 105 is 15-20mm, and the width is 1-2mm larger than the width of the longitudinal reinforcing rib 3. After snap-fitting, elastic rubber strips are filled in the gap between the snap-fit ​​groove 105 and the longitudinal reinforcing rib 3 to enhance the connection sealing and stability. The base plate 5 is welded to the grid frame 2, and the reinforcing plate 101 is welded to the grid plate 1, both using carbon dioxide gas shielded welding.

[0034] Example 2:

[0035] Based on Embodiment 1, a base plate 5 is fixedly connected to the bottom of the grid frame 2, and a water collection tank 4 is connected to the top of the base plate 5. A water leakage hole is opened at the bottom of the inner wall of the water collection tank 4, which passes through the water collection tank 4 and the base plate 5. The bottom surface of the grid frame 2 is provided with raised particles, and the lower surface of the base plate 5 is provided with an anti-slip pad. The anti-slip pad is made of nitrile rubber and has diamond-shaped anti-slip patterns.

[0036] Take the base plate 5 and fix the water collection tank 4 to its top with bolts. The bottom of the inner wall of the water collection tank 4 needs to be pre-drilled with a water leakage hole 6 that penetrates the water collection tank 4 and the base plate 5 to ensure that the water leakage hole 6 is unobstructed.

[0037] The bottom plate 5 of the assembled water collection tank 4 is fixedly connected to the bottom of the grating frame 2 by welding. After welding, the weld is treated with anti-corrosion to prevent rust and damage during long-term use. At the same time, raised particles made of rubber are pasted on the bottom surface of the grating frame 2 and fixed with strong adhesive to enhance the friction between the grating frame 2 and the bottom plate 5.

[0038] An anti-slip mat is laid on the lower surface of the base plate 5. The anti-slip mat is made of nitrile rubber and has a diamond-shaped anti-slip pattern pressed on its surface. The anti-slip mat is fixed to the base plate 5 with bolts to ensure that the anti-slip mat will not shift during use and to improve the anti-slip performance of the entire grid structure.

[0039] The water collection tank 4 is fixed to the base plate 5 with M8-M10 stainless steel bolts. The bolt spacing is 150-200mm and the bolt tightening torque is 25-30N·m to ensure a firm connection.

[0040] For the bonding of raised particles on the bottom surface of the grid frame 2, the raised particles are 3-5mm in diameter and 2-3mm in height, distributed in a matrix pattern with a spacing of 20-30mm. Epoxy resin is used as the strong adhesive, with a coating thickness of 0.5-1mm and a curing time of 24 hours. Clearly define the particle parameters and bonding process to ensure the friction enhancement effect.

[0041] Working principle:

[0042] The reinforcing plate 101 on the grating 1 is made of high-strength alloy material, which can effectively disperse the external force borne by the grating 1, improve the overall load-bearing capacity, and prevent the grating 1 from deforming under heavy pressure. The transverse reinforcing ribs 106 intersect perpendicularly with the longitudinal reinforcing ribs 3 and have a trapezoidal cross-section. This structural design can further enhance the bending resistance of the grating structure, evenly transfer the external load to the entire grating frame, and ensure the stability and reliability of the structure in civil engineering applications.

[0043] When rainwater or other accumulated water falls onto the grating plate 1, some of the water quickly seeps down through the larger aperture 102, filtering out larger particles of impurities. The remaining water is further filtered through the smaller aperture 104, intercepting smaller particles of impurities, achieving a staged filtration effect. The filtered water falls into the collection tank 4 below. Because the bottom of the collection tank 4 is inclined at 5-8°, the water flows towards the lowest end of the collection tank 4 under the action of gravity and is finally discharged through the drain hole 6, preventing water from accumulating inside the grating structure and preventing damage to the structure due to long-term immersion.

[0044] The uniformly distributed metal protrusions 103 on the upper surface of the grating plate 1, with a height of 3-5mm, increase the friction of the contact surface, effectively preventing slippage when personnel or equipment move on the grating plate 1. The nitrile rubber anti-slip pad and the diamond-shaped anti-slip texture on the lower surface of the base plate 5 enhance the adhesion between the base plate 5 and the mounting surface, preventing displacement of the grating structure during use. At the same time, the raised particles on the bottom surface of the grating frame 2 increase the contact friction between the grating frame 2 and the base plate 5, further improving the stability of the overall structure.
