Description

Technical Field

[0001] This utility model relates to the field of drainage ditch cover installation structure, specifically a linear drainage ditch cover installation structure. Background Technology

[0002] Currently, with the accelerating pace of urbanization and the booming commercial development, various commercial plazas are springing up like mushrooms after rain, becoming important venues for urban residents' leisure, shopping, and entertainment. From an architectural design and decoration perspective, the choice of paving materials for commercial plazas is crucial, and stone is currently the most commonly used material. Stone, with its unique texture, rich colors, and high durability, has become the preferred material for commercial plaza paving. It not only creates a grand and upscale atmosphere for the plaza but also withstands the trampling of large crowds and the test of various complex environments, maintaining its beauty and practicality over the long term.

[0003] However, there are some problems with the installation of traditional linear drainage ditch covers. For example, the construction is relatively complicated by using pre-embedded steel bars and angle iron or expansion bolts on site. Moreover, the load-bearing capacity of ordinary covers is insufficient. When a car passes over them, the stainless steel plates are prone to deformation, resulting in a high maintenance rate. In addition, the addition of a separate bottom square tube can easily cause water to seep in from the gaps in the stone and the edges of the linear holes when there is heavy rainfall. This can wash away the sand and mortar layer at the bottom of the stone, causing the stone to become hollow and warped. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a linear drainage ditch cover installation structure to solve the technical problems of complex installation and construction of traditional linear drainage ditch covers, insufficient load-bearing capacity of ordinary covers leading to easy deformation and high maintenance rate, and rainwater easily seeping through the gaps and dispersing the sand and ash layer at the bottom of the stone when a separate square tube is added at the bottom, causing the stone to become hollow and warped.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a linear drainage ditch cover installation structure, including a ditch structure, angle steel is provided on both sides of the inner wall of the ditch structure, and a square steel pipe is installed on the top of the angle steel. A stainless steel cover plate is provided on the top of the square steel pipe, and a linear groove composed of multiple transverse steel plates and longitudinal steel plates is provided at the central axis of the stainless steel cover plate.

[0006] The stainless steel cover plate has vertical water-blocking steel plates on both sides, the height of which is flush with the bottom surface of the paved stone, and the water-blocking steel plates are sealed to the angle steel by welding or weather-resistant sealant.

[0007] By adopting the above technical solutions, the trench structure provides a stable foundation, angle steel and square steel pipes form a rigid framework, and stainless steel cover plates ensure surface durability. Water-blocking steel plates achieve lateral sealing, preventing water seepage from eroding the base structure and improving overall waterproof reliability.

[0008] Furthermore, the angle steel, square steel pipe, stainless steel cover plate, transverse steel plate, longitudinal steel plate, water-blocking steel plate and three-dimensional composite drainage net constitute a linear trench cover plate, and the linear trench on the linear trench cover plate is provided with a U-shaped groove inside.

[0009] By adopting the above technical solution, components such as angle steel and square steel pipe are solidified into standard units, and U-shaped slots are built into linear grooves, which simplifies the installation process, improves the efficiency of modular construction, and reduces the difficulty of on-site adjustments.

[0010] Furthermore, multiple linear trench covers composed of angle steel, square steel pipe, stainless steel cover plate, transverse steel plate, longitudinal steel plate, water-blocking steel plate and three-dimensional composite drainage net are provided. The multiple linear trench covers adopt a segmented design, and adjacent linear trench covers are connected by U-shaped slots and reinforced by welded fasteners at the joints.

[0011] By adopting the above technical solution, the segmented cover plate achieves rapid interlocking and positioning through U-shaped slots, and the welded fasteners strengthen the joint connection, ensuring that the multi-segment cover plate maintains straightness accuracy, thereby improving installation quality and aesthetics.

[0012] Furthermore, the stainless steel cover plate has two rows of filter holes on its surface, with the holes located in the middle area between adjacent square steel pipes.

[0013] By adopting the above technical solution, the filter holes are precisely set in the middle area of ​​the gap between the square steel pipes, avoiding the load-bearing structure, ensuring the smooth flow of the holes, optimizing the water intake efficiency, and preventing blockage that could lead to drainage failure.

[0014] Furthermore, a three-dimensional composite drainage net is provided between the linear groove formed by the transverse steel plate and the longitudinal steel plate and the water-blocking steel plate, and the three-dimensional composite drainage net is mounted on the stainless steel cover plate. The three-dimensional composite drainage net is used to accelerate the infiltration of surface rainwater.

[0015] By adopting the above technical solution, a three-dimensional composite drainage net is laid between the trench and the baffle. The three-dimensional mesh structure accelerates rainwater infiltration, prevents sand particles from entering the system, and protects the integrity of the base structure.

[0016] Furthermore, the angle steel and square steel pipe are connected by welding or bolts to form a load-bearing frame.

[0017] By adopting the above technical solution, the rigid connection between angle steel and square steel tube forms a gradient force transmission structure, optimizes load distribution, enhances compressive and deformation resistance, and extends service life.

[0018] Furthermore, cement mortar and paving stones are laid sequentially above the three-dimensional composite drainage network to form an integrated anti-seepage and drainage paving layer.

[0019] By adopting the above technical solution, cement mortar and paving stones form a closed paving surface above the drainage network, achieving an organic unity of surface aesthetics and drainage function.

[0020] Furthermore, the bottom layered foundation structure of the trench structure consists of rammed subsoil, a cement-stone powder cushion layer, and a concrete base layer.

[0021] By adopting the above technical solutions, the material stiffness is gradually increased, the bearing capacity of the transition foundation is improved, settlement and deformation are prevented, and the long-term stability of the ditch structure is ensured.

[0022] In summary, the present invention has the following main advantages:

[0023] This utility model features an assembly structure consisting of a first linear trench cover, a second linear trench cover, and a U-shaped groove; a bottom square steel pipe; angle steel; and a water-blocking steel plate; as well as a multi-layered drainage channel of a three-dimensional drainage network. The first and second linear trench covers are assembled using a U-shaped groove, replacing traditional pre-embedded steel bars or expansion bolts for rapid installation, thus solving the problem of complex construction procedures. The grid-like support frame composed of angle steel and hot-dip galvanized square steel pipe directly supports the cover assembly, dispersing pressure loads through a rigid skeleton and significantly improving the cover's resistance to deformation. This solves the problems of easy deformation and high maintenance rates caused by insufficient load-bearing capacity of ordinary covers. Simultaneously, the water-blocking steel plate is continuously laid along the top of the longitudinal steel plate to form a closed water-blocking layer. Combined with the drainage holes in the trench wall and the drainage channel formed by the three-dimensional drainage network, it effectively prevents rainwater from seeping into the paving layer, completely solving the problem of rainwater seeping through stone gaps and scattering the sand and mortar layer, causing the stone to become hollow and warp.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] A linear drainage ditch cover installation structure, such as Figure 1-4 As shown, it includes a trench structure 108, with angle steel 106 provided on both sides of the inner wall of the trench structure 108, and a square steel pipe 105 installed on the top of the angle steel 106. A stainless steel cover plate 107 is provided on the top of the square steel pipe 105, and a linear trench composed of multiple transverse steel plates 101 and longitudinal steel plates 102 is provided at the central axis of the stainless steel cover plate 107.

[0031] The stainless steel cover plate 107 has vertical water-blocking steel plates 104 on both sides, with their height being flush with the square steel pipe 105. The water-blocking steel plates 104 and the angle steel 106 are sealed by welding or weather-resistant sealant. This structure uses the trench structure 108 as the main load-bearing body. The angle steel 106 on both sides of the inner wall and the square steel pipe 105 at the top together form a rigid support frame to ensure effective load transfer. The stainless steel cover plate 107 is covered with a corrosion-resistant material for the frame layer. The linear trench set at its central axis is formed by transverse steel plates 101 and longitudinal steel plates 102 to form a directional drainage channel. The vertical water-blocking steel plates 104 on both sides are flush with the height of the square steel pipe 105 and are sealed to the angle steel 106 by welding or weather-resistant sealant to form a continuous waterproof barrier, effectively blocking the lateral water seepage path and preventing the bottom sand and ash layer from being washed away and causing structural damage.

[0032] See Figure 1 , Figure 2 , Figure 3Angle steel 106, square steel pipe 105, stainless steel cover plate 107, transverse steel plate 101, longitudinal steel plate 102, water-blocking steel plate 104, and three-dimensional composite drainage net 103 constitute a linear trench cover. The linear trench cover has a U-shaped slot 115 inside the linear trench. The linear trench cover integrates angle steel 106, square steel pipe 105, stainless steel cover plate 107, transverse steel plate 101, longitudinal steel plate 102, water-blocking steel plate 104, and three-dimensional composite drainage net 103 as a standardized unit, realizing factory prefabrication and rapid on-site assembly. The U-shaped slot 115 is built into the structural design of the linear trench, forming a precise positioning interface. The mechanical locking replaces the traditional bolt connection, significantly reducing the installation complexity, avoiding the adjustment work caused by on-site dimensional errors, and ensuring the structural continuity when splicing multiple units.

[0033] See Figure 1 , Figure 2 , Figure 3 Multiple linear trench covers, composed of angle steel 106, square steel pipe 105, stainless steel cover plate 107, transverse steel plate 101, longitudinal steel plate 102, water-blocking steel plate 104, and three-dimensional composite drainage net 103, are installed. These linear trench covers adopt a segmented design, and adjacent linear trench covers are connected by U-shaped slots 115. They are reinforced at the joints 119 by welded fasteners 116. The segmented design of multiple linear trench covers achieves initial positioning through the guiding engagement of the U-shaped slots 115, and then secondary reinforcement is carried out at the joints 119 by welded fasteners 116. This dual connection mechanism retains the convenience of snap-fit ​​installation while enhancing the rigidity of the nodes through welding, effectively eliminating the cumulative error when splicing multiple cover sections, ensuring the straightness accuracy of the overall linear trench, avoiding drainage problems caused by misalignment, and improving the flatness and visual aesthetics of the road surface.

[0034] See Figure 1 , Figure 2 , Figure 3 The stainless steel cover plate 107 has two rows of filter holes 114 on its surface. The holes are located in the middle area between adjacent square steel pipes 105. The two rows of filter holes 114 on the surface of the stainless steel cover plate 107 are strictly positioned in the middle area between adjacent square steel pipes 105, making full use of the gap space of the supporting frame. This layout design avoids the filter holes 114 from overlapping with the load-bearing square steel pipes 105, which maintains the overall structural strength of the cover plate and ensures that the holes are not squeezed or deformed, so that surface water can seep into the trench system without obstacles, significantly reducing the risk of particulate matter blockage and maintaining long-term drainage efficiency.

[0035] See Figure 1 , Figure 2 , Figure 3A three-dimensional composite drainage net 103 is installed between the linear trench formed by the transverse steel plate 101 and the longitudinal steel plate 102 and the water-blocking steel plate 104. The three-dimensional composite drainage net 103 is mounted on the stainless steel cover plate 107. The three-dimensional composite drainage net 103 is used to accelerate the infiltration of surface rainwater. The three-dimensional composite drainage net 103 is laid in the area between the linear trench formed by the transverse steel plate 101 and the longitudinal steel plate 102 and the water-blocking steel plate 104. Its three-dimensional mesh structure forms multiple water-guiding channels. This design significantly improves the rainwater infiltration rate. At the same time, it intercepts mud and sand particles through the mesh filtration mechanism to prevent the filter holes 114 from being blocked. The close mounting relationship between the drainage net 103 and the stainless steel cover plate 107 disperses the impact force of water flow and avoids rainwater directly washing the cement mortar 112 bonding layer, fundamentally reducing the risk of hollowing of the stone paving layer 113.

[0036] See Figure 1 , Figure 2 , Figure 3 Angle steel 106 and square steel pipe 105 are connected by welding or bolts to form a load-bearing frame. Angle steel 106 and square steel pipe 105 are rigidly connected by welding or bolts to construct a gradient force transmission path: vertical loads are transmitted to square steel pipe 105 through stainless steel cover plate 107, then distributed to angle steel 106, and finally borne by trench structure 108. This frame design optimizes stress distribution, avoids cover plate deformation caused by local overload, significantly improves resistance to vehicle crushing, and ensures long-term stability by eliminating the risk of loosening between components.

[0037] See Figure 1 , Figure 4 Cement mortar 112 and paving stones 113 are laid sequentially on top of the three-dimensional composite drainage net 103 to form an integrated anti-seepage and drainage paving layer. Cement mortar 112 bonding layer and paving stones 113 are laid sequentially on top of the three-dimensional composite drainage net 103 to form an integrated anti-seepage and drainage paving system. Cement mortar 112 fills the gaps on the surface of the drainage net 103 to form a sealing layer, blocking the path of rainwater infiltration. Paving stones 113 provide a flat and wear-resistant surface, and their gaps and filter holes 114 form a coordinated drainage channel to achieve rapid collection and diversion of surface water, maintaining drainage efficiency while ensuring the aesthetics of the paving.

[0038] See Figure 1 , Figure 4The layered foundation structure at the bottom of the ditch structure 108 consists of rammed subsoil 109, cement-stone powder cushion layer 110, and concrete base layer 111. The layered foundation at the bottom of the ditch structure 108 adopts a composite structure of rammed subsoil 109, cement-stone powder cushion layer 110, and concrete base layer 111. The rammed subsoil 109 provides a uniform bearing layer, the cement-stone powder cushion layer 110 achieves stiffness transition and blocks capillary water rise, and the concrete base layer 111 forms a rigid support surface. This layered design effectively disperses the load and suppresses foundation settlement through the gradient change of material modulus, ensuring the long-term stability of the drainage slope of the ditch structure 108.

[0039] The implementation principle of this embodiment is as follows: First, a trench structure 108 is constructed on the layered foundation structure, including rammed soil 109, cement stone powder cushion layer 110 and concrete base layer 111, to provide a stable support foundation for the overall structure. Angle steel 106 is precisely installed on both sides of the inner wall of the trench structure 108 to form the main load-bearing boundary.

[0040] Next, square steel pipes 105 are fixed to the top of angle steel 106 by welding or bolting to form a grid-like load-bearing frame. The square steel pipes 105 are evenly distributed at a preset interval to ensure effective load transfer.

[0041] Subsequently, a stainless steel cover plate 107 is laid on top of the square steel pipe 105. A linear groove system consisting of a transverse steel plate 101 and a longitudinal steel plate 102 is set at the central axis of the cover plate. Simultaneously, a water-blocking steel plate 104 that is flush with the height of the square steel pipe 105 is installed, and a sealed connection with the angle steel 106 is achieved by welding or weather-resistant sealant to form a continuous waterproof barrier.

[0042] Then, U-shaped slots 115 are precisely assembled inside the linear trench to provide an interface for subsequent modular splicing. Two rows of filter holes 114 are opened on the surface of the stainless steel cover plate 107, with their positions strictly corresponding to the gap area of ​​the square steel pipe 105 to ensure smooth drainage.

[0043] Next, a three-dimensional composite drainage net 103 is laid to cover the entire surface of the stainless steel cover plate 107. Its three-dimensional mesh structure forms an efficient water-guiding layer, which accelerates rainwater infiltration and prevents particulate matter from clogging the system.

[0044] Finally, a segmented installation process is adopted: adjacent cover plates are precisely interlocked through U-shaped slots 115, and welded fasteners 116 are used to reinforce the connection at the joints 119; cement mortar 112 bonding layer and paving stone 113 are laid sequentially on top of drainage net 103 to form a complete surface drainage closed system.
