Description

Technical Field

[0001] This utility model relates to the field of lining plate technology, specifically to a prefabricated modular underwater slope lining plate. Background Technology

[0002] After prolonged use, underwater slope lining slabs often experience damage in certain areas, requiring repair. However, due to the continuous water supply from the main water conveyance canal, it is not feasible to carry out the repair work while the water is cut off. Furthermore, under the conditions of water conveyance in the canal, the water depth of the underwater lining slab repair section is several meters, and the bottom of the canal usually does not have the conditions to anchor and erect a fully enclosed cofferdam. Therefore, underwater repair construction needs to be considered.

[0003] Existing underwater lining repair methods often require installing steel formwork, pouring concrete, and then removing the formwork, making the entire construction process extremely cumbersome and inefficient. Another approach is to prefabricate lining slabs and install them directly underwater. However, during the lowering process, the adjacent planes of existing prefabricated lining slabs are usually perpendicular to each other. This causes the water flow to continuously impact the end faces of the lining slabs during lowering and installation, affecting their stability and making it difficult to position and fix the prefabricated lining slabs throughout the entire construction process.

[0004] Based on the above background, the inventors designed a prefabricated modular underwater slope lining slab to solve at least one of the above problems, and thus, this application is hereby filed. Summary of the Invention

[0005] The purpose of this application is to provide a prefabricated modular underwater slope lining panel to solve the problem in the prior art where the water flow has a large impact on the lining panel when disassembling and assembling it in the water flow environment of an underwater slope, which makes it inconvenient for construction personnel to install.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0007] This application provides a prefabricated modular underwater slope lining slab, including a slab body, the slab body including a main body and a first connecting part and a second connecting part disposed on two opposite end faces of the main body;

[0008] The cross-sectional shape of the first connecting part and / or the second connecting part away from the main body is an acute angle.

[0009] Adjacent plates along the water flow direction are connected and fixed by a first connecting part and a second connecting part;

[0010] When two adjacent plates along the water flow direction are spliced ​​together, the cross-sectional shape of the first and second connecting parts after splicing is rectangular.

[0011] Optionally, the cross-sectional shape of both the first connecting part and the second connecting part is a right-angled triangle;

[0017] Optionally, it also includes a plug-in connecting rod for insertion into the first connecting through hole and the second connecting through hole.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 3 As shown, this embodiment provides a prefabricated modular underwater slope lining slab, including a slab body 1. The slab body 1 includes a main body 11 and a first connecting part 12 and a second connecting part 13 disposed on two opposite end faces of the main body 11.

[0033] The cross-sectional shape of the first connecting portion 12 and / or the second connecting portion 13 at the end away from the main body portion 11 is an acute angle.

[0034] Adjacent plates 1 along the water flow direction are connected and fixed by a first connecting part 12 and a second connecting part 13;

[0035] When two adjacent plates 1 are spliced ​​together along the direction of water flow, the cross-sectional shape of the first connecting part 12 and the second connecting part 13 after splicing is rectangular, ensuring that the adjacent plates 1 have sufficient structural strength after being connected.

[0036] In this embodiment, a first connecting portion 12 and a second connecting portion 13 are provided on both sides of the main body 11 of the plate 1. The longitudinal cross-sectional shape of the ends of the first connecting portion 12 and the second connecting portion 13 away from the main body 11 is an acute angle. This allows the plate 1, after being lowered into the water, to avoid the water flow directly impacting the end face of the plate 1, thus preventing excessive water impact and inconvenience for installation personnel.

[0037] In this embodiment, the cross-sectional shape of the first connecting part 12 and the second connecting part 13 is a right triangle;

[0038] The cross-sectional shape of the plate 1 is either a parallelogram or a rectangular shape, so that after two adjacent plates 1 have a first connecting part 12, they can be directly rotated horizontally by 180° underwater to make the first connecting part 12 and the second connecting part 13 adjacent again, which is convenient for construction personnel. In some embodiments, the shape of the plate 1 can also be an isosceles trapezoid or the like.

[0039] In this embodiment, the included angle between the cross sections of the first connecting part 12 and the second connecting part 13 at the end away from the main body part 11 is in the range of 30° to 60°, so as to avoid problems such as the concrete being difficult to form and easily damaged due to the included angle being too small.

[0040] Specifically, the included angle of the cross sections of the first connecting part 12 and the second connecting part 13 at the ends away from the main body 11 is 40°, to ensure that the first connecting part 12 and the second connecting part 13 have sufficient strength. At the same time, it is ensured that the included angle of the cross sections of the first connecting part 12 and the second connecting part 13 at the ends away from the main body 11 is small, so as to avoid excessive impact force of water flow on the first connecting part 12 or the second connecting part 13.

[0041] In this embodiment, the first connecting part 12 and the second connecting part 13 are respectively provided with a plurality of first connecting through holes 121 and second connecting through holes 131 that are matched in number and position. By providing the first connecting through holes 121 and second connecting through holes 131 on the first connecting part 12 and the second connecting part 13, it is convenient for construction personnel to connect the two adjacent plates 1.

[0042] In this embodiment, a plug-in connecting rod 2 is also included for insertion into the first connecting through hole 121 and the second connecting through hole 131. The plug-in connecting rod 2 in this embodiment can be made of stainless steel or the same material as the plate 1, and is connected to the first connecting through hole 121 and the second connecting through hole by interference fit.

[0043] In this embodiment, the first connecting part 12 and the second connecting part 13 are respectively provided with a first positioning structure and a second positioning structure that match each other, so as to facilitate the alignment operation of adjacent plates 1 during underwater installation and connection, so that adjacent plates 1 can be quickly aligned and the axes of adjacent first connecting through holes 121 and second connecting through holes 131 can be aligned, thereby facilitating the construction personnel to insert the plug-in connecting rod 2 and complete the installation and fixing of adjacent plates 1.

[0044] In this embodiment, the first positioning structure is a positioning protrusion 122, and the second positioning structure is a positioning groove 132. The shapes and positions of the positioning protrusion 122 and the positioning groove 132 are adapted to each other.

[0045] In this embodiment, the positioning protrusion 122 and the positioning groove 132 have curved cross-sectional shapes. This facilitates water flow to bypass the positioning protrusion 122 or the positioning groove 132, avoiding increasing the impact force of the water flow on the plate 1.

[0046] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
