Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a splicing and locking structure for anti-scour lining plates of water conservancy channels. Background Technology

[0002] In water conservancy projects, lining plates are typically laid at the bottom and slopes of channels to improve their erosion resistance, reduce soil erosion, and extend their service life. The main function of the lining plates is to protect the channel surface and prevent long-term water erosion from causing damage to the foundation or localized collapse.

[0003] Common erosion lining structures primarily employ precast panels for assembly. These lining panels are typically spliced ​​together in blocks, with adjacent panels connected by simple overlaps, mortar grouting, or localized bolt fixing. While this structure is relatively convenient to construct, it still has some significant technical shortcomings in practical applications, resulting in poor splicing and locking effects, for example: First, the splicing method is loose, and there is no good locking structure between the lining plates, which makes it easy for the plates to misalign and open when laid over a long distance. The overall connection strength is insufficient, and deformation is more likely to occur, especially when the channel experiences slight settlement or is impacted by water flow. Secondly, the lining in the slope area is not firm. The lining pieces on the slope often become loose due to thermal expansion and contraction or shear impact. The splicing joints are easily torn by water flow, resulting in poor continuity of the lining structure and easy to be lifted. Third, uneven stress distribution, with mortar filling or manual pressing between panels, often leads to quality problems such as bulging, warping, and cracking, increasing later maintenance costs.

[0004] Therefore, there is an urgent need for a locking structure for splicing anti-scour lining plates in water conservancy channels to solve the above-mentioned technical defects. Utility Model Content

[0005] The purpose of this utility model is to provide a splicing and locking structure for anti-scour lining plates in water conservancy channels, so as to solve the problem of poor splicing and locking effect of lining plates mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a scour-resistant lining plate splicing and locking structure for a water conservancy channel, comprising: a channel body, which is the main body of the water conservancy channel; a main lining plate, which is a trapezoidal plate matching the shape of the bottom and slope of the channel body, the main lining plate is split, the main lining plate is assembled on the inner wall of the channel, the two sides of the main lining plate extend to the slope of the channel body, and slope wing plates are laid on the slope surface; a connecting plate, which is a strip steel plate with grooves on both sides, installed between two adjacent main lining plates for splicing the plates; an anchoring pad, which is bonded to the bottom of the main lining plate for filling the contact surface between the main lining plate and the channel body; and an elastic buffer pad, which is bonded to the bottom of the slope wing plate for absorbing thermal expansion and contraction of the contact surface between the slope wing plate and the channel body.

[0007] As a further technical solution of this utility model, the main lining plate and the slope wing plate abut against each other at their edges, and a locking steel plate is fixedly connected between the main lining plate and the slope wing plate.

[0008] As a further technical solution of this utility model, the slope wing and the elastic buffer pad are fixedly connected by fixing bolts.

[0009] As a further technical solution of this utility model, one set of connecting side edges of the slope wing is machined with plate grooves, and the other connecting side edge is machined with plate protrusions. Adjacent sets of slope wing pieces are joined together by plate grooves and plate protrusions.

[0010] As a further technical solution of this utility model, the connection point of the elastic buffer pad and the anchoring pad is processed into a wedge-shaped groove structure that fits into each other, and the locking steel sheet is used to connect and fix the main lining plate, the slope wing plate and the elastic buffer pad by bolts.

[0011] As a further technical solution of this utility model, the opening of the locking steel plate is 120°, and the opening side of the locking steel plate is attached to the side wall of the channel and the surface of the slope.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the structure forms a guide splicing between the main lining plates through the connecting plate, and ensures the connection tightness of long-distance lateral splicing through the slot structure of the slope wing plate. With the help of locking steel plates, fixing bolts and elastic buffer pads, longitudinal, lateral and oblique locking is achieved, so that the overall lining structure has excellent integrity, density and erosion resistance, and has a better splicing and locking effect for complex water conservancy channels.

[0015] 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.

[0016] Please see Figure 1-4 The present invention provides an embodiment of the following: a channel structure 1, which is the main body of the water conservancy channel; a main lining plate 4, which is a trapezoidal plate that matches the shape of the bottom and slope of the channel structure 1; the main lining plate 4 is a split type and is assembled on the inner wall of the channel; the two sides of the main lining plate 4 extend to the slope of the channel structure 1; slope wing plates 7 are laid on the surface of the slope; and a connecting plate 2, which is a strip steel plate with grooves on both sides, is installed between two adjacent main lining plates 4 for splicing the plates. Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the main lining plate 4 is a split structure. The main body is installed on the inner wall of the channel structure 1. A connecting plate 2 is set between two adjacent main lining plates 4, and an I-shaped interlocking structure is adopted to splice them along the water flow direction to form a stable connection. The two sides of the main lining plate 4 extend upward to the channel slope area, and slope wing plates 7 are laid at the slope. The slope wing plates 7 are connected and fixed to the main lining plate 4 by locking steel plates 5, so that the entire lining structure can still maintain the integrity of the plate under the action of fluid scouring and is not easy to move or fall off.

[0017] Anchor plate 3 is bonded to the bottom of the main lining plate 4 and is used to fill the contact surface between the main lining plate 4 and the channel structure 1. Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the anchoring plate 3 is placed at the bottom of the main lining plate 4 to fill the gap between the main lining plate 4 and the channel structure 1. After the bottom surface or slope of the channel structure 1 is poured, there is no need to carry out fine leveling or grinding operations. The main lining plate 4 can be laid directly, which improves the installation efficiency and reduces the requirements of the foundation treatment process for construction accuracy.

[0018] The slope wing 7 has a plate groove 6 on one connecting side edge and a plate protrusion 10 on the other connecting side edge. The two adjacent sets of slope wing 7 are spliced ​​together by the plate groove 6 and the plate protrusion 10. Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one set of connecting side edges of the slope wing 7 is machined with plate grooves 6, and the other set of connecting side edges is machined with plate protrusions 10. During installation, the two adjacent sets of slope wing 7 are spliced ​​by the interlocking cooperation between the plate grooves 6 and the plate protrusions 10. The interlocking direction is consistent with the direction of channel water flow, which enhances the structure's resistance to falling off and has a self-reinforcing locking effect when subjected to water flow impact, which is conducive to maintaining the continuity of long-distance laying.

[0019] The elastic buffer pad 9 is bonded to the bottom of the slope wing 7 and is used to absorb the thermal expansion and contraction of the contact surface between the slope wing 7 and the channel structure 1. Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connection point between the elastic buffer pad 9 and the anchor plate 3 is processed into a wedge-shaped groove 11 structure, which is mutually concave and convex, and can provide a certain pre-tightening force and shear resistance to prevent relative sliding between the elastic buffer pad 9 and the anchor plate 3; at the same time, the slope wing 7, the main lining plate 4 and the elastic buffer pad 9 are locked together by setting the locking steel plate 5, and are pressed one by one by the fixing bolts 8, which has high resistance to deformation.

[0020] The main lining plate 4 and the slope wing 7 abut against each other at their edges. A locking steel plate 5 is fixedly connected between the main lining plate 4 and the slope wing 7. A fixing bolt 8 is fixedly connected between the slope wing 7 and the elastic buffer pad 9. Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the locking steel plate 5 adopts a 120° opening design, with the opening facing the slope direction of the channel structure 1. Its outline fits the side wall of the main lining plate 4 and the outer surface of the slope wing 7. After installation, the three can be pressed tightly onto the surface of the channel structure 1 through the wedge action. Even when the slope section is subjected to oblique impact of water flow and slight deformation of the foundation, it can still maintain a high-strength connection state and extend the service life of the structure.

[0021] Working principle: During construction, firstly, according to the outline of the channel structure 1 after pouring, the main lining slabs 4 are laid sequentially at the bottom and slope of the channel. The main lining slabs 4 are split trapezoidal structures, and anchoring plates 3 are set between the bottom of the main lining slabs and the channel structure 1. The anchoring plates 3 are used to fill any unevenness or gaps that may exist between the channel structure 1 and the main lining slabs 4, so that the main lining slabs 4 can be quickly and stably positioned without extensive grinding and leveling, reducing the workload of foundation treatment. Subsequently, adjacent main lining slabs 4 are connected by... Connecting plate 2 enables splicing. Connecting plate 2 is a strip structure with grooves on both sides to form an I-shaped fit with the side of the main lining plate 4, allowing the splicing direction to extend along the water flow direction, forming a linear locking connection and improving the anti-slip performance at the splice. The upper end of the main lining plate 4 extends to the slope area, and slope wing plates 7 are laid on the slope surface of the channel structure 1. An elastic buffer pad 9 is provided between the bottom of the slope wing plate 7 and the slope of the channel structure 1. The elastic buffer pad 9 is used to absorb the thermal expansion caused by temperature changes between the slope wing plate 7 and the channel structure 1. Cold shrinkage deformation enhances the structure's adaptability to deformation and reduces the risk of bulging or cracking caused by rigid bonding of panels. To achieve linear splicing of the slope wing 7, plate grooves 6 and plate protrusions 10 are respectively provided between two adjacent sets of slope wing 7. Assembly is completed through the interlocking of the two, with the interlocking direction consistent with the water flow direction. During long-term water scouring, it can automatically enhance the splicing tightness and prevent the structure from loosening due to shear force. The splicing interface between the slope wing 7 and the main lining plate 4 is fixed as a whole by locking steel plates 5. The design adopts a 120° opening, with the opening surface conforming to the curved surface of the channel structure 1 slope. After installation, the main lining plate 4, the slope wing 7, and the elastic buffer pad 9 are pressed together by the wedge action of the locking steel plate 5, forming a highly stable clamping connection. Each structure is locked by the sequential insertion of fixing bolts 8, which improves the tensile strength and scour resistance of the connection. The elastic buffer pad 9 and the anchoring plate 3 are interlocked by a wedge-shaped groove 11 structure to form a highly pre-tight fit structure, preventing loosening or wear between the contact surfaces due to micro-vibration or micro-displacement.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
