Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a drainage trough for water conservancy projects. Background Art

[0002] A water conservancy project is a project built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. It is also called a water project. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging, and regulate and distribute water to meet people's needs for water resources in life and production. Drainage ditches are one of the most commonly used water conservancy project facilities.

[0003] In the related art, most common drainage gutters are made up of several prefabricated trough blocks. During installation, a trench is opened on the ground, and then several prefabricated trough blocks are installed and laid in the trench along the direction of the trench opening, and adjacent prefabricated trough blocks are spliced ​​end to end. After the laying is completed, cement is applied at the splicing position.

[0004] In the process of implementing this application, it was found that there are at least the following problems in this technology: the entire drainage trough is spliced ​​together by multiple prefabricated trough blocks, and cement is only applied at the splicing positions. When the drainage trough is subjected to impact or a large load, the cement is prone to cracks, causing water seepage, making it difficult to maintain a good sealing effect, which may cause the ground where the drainage trough is installed to collapse. Utility Model Content

[0005] In order to improve the sealing strength of the splicing position and avoid the occurrence of water seepage as much as possible, the present application provides a drainage trough for water conservancy projects.

[0006] The present application provides a drainage trough for a water conservancy project using the following technical solution:

[0007] A drainage trough for water conservancy projects, comprising an outer slat and prefabricated trough blocks, wherein the outer slat comprises a bottom plate and side plates, the side plates are inclined and fixedly arranged at both ends of the bottom plate, a plurality of prefabricated trough blocks are evenly laid, and the end walls of adjacent prefabricated trough blocks are abutted against each other, fitting grooves are opened at the outer walls at both ends of the prefabricated trough blocks, the fitting grooves are for the bottom plate and the side plates to be inserted, and the outer slat and the fitting grooves are adapted to each other.

[0008] By adopting the above technical scheme, when installing and laying the drainage trough, the cement used for sealing is applied between the fitting groove and the outer floor plate, which greatly increases the cement bonding area, thereby improving the bonding strength of the cement, improving the bearing capacity and impact resistance of the cement, and making the cement less likely to crack. In addition, the bonding cement is arranged between the fitting groove and the outer floor plate, so that the cement is not directly on the surface of the drainage trough, and the impact cannot directly act on the cement. The impact on the surface of the drainage trough can only be indirectly transmitted to the cement bonding position. During the transmission process, the grooves on the ground will play a shock-absorbing role, and a large amount of impact will be shared and absorbed by the ground, which greatly reduces the damage to the cement layer caused by the impact. The outer floor plate itself also helps to prevent the direct penetration and outflow of liquid. In summary, the sealing strength of the splicing position is improved, which helps to avoid the occurrence of water seepage.

[0009] Preferably, a limiting block is fixedly provided on the inner wall of the bottom plate of the outer floor plate, and a limiting groove is opened on the fitting groove, and the limiting block can be inserted into the limiting groove and fit and abut against the limiting groove.

[0010] By adopting the above technical solution, the drainage trough may be subjected to loads or impacts mostly perpendicular to the direction of the base plate. The limiting block is inserted into the limiting groove and fits and offsets the limiting groove, which limits the bending tendency of the two adjacent prefabricated trough blocks perpendicular to the direction of the base plate, and improves the stability of the connection between the prefabricated trough blocks and the prefabricated troughs. In addition, the limiting block hinders the direct connection of the adhesive cement layers on both sides of the limiting block, and minimizes the spread of cracks to another piece of adhesive cement when cracks appear in one piece of adhesive cement.

[0011] Preferably, the limiting block is wrapped with a rubber layer.

[0012] By adopting the above technical solution, even if cracks appear on the bonding cement, the rubber layer can seal the liquid that penetrates out, further improving the sealing strength of the splicing position and avoiding the occurrence of water seepage.

[0013] Preferably, the limiting block is arranged in a step shape.

[0014] By adopting the above technical solution, during the installation process, the positioning of the limiting block in the operation of inserting the limiting groove is facilitated, which helps to reduce the friction between the rubber layer and the inner wall of the limiting groove.

[0015] Preferably, first pile grooves are provided on both side walls of the fitting groove, and second pile grooves are provided on the side plates, and square piles are inserted into both the first pile groove and the second pile groove.

[0016] By adopting the above technical solution, after installing the outer floor plate and the prefabricated trough body, the square piles are driven into the first pile groove and the second pile groove, which helps to improve the stability and sealing strength of the side walls of the drainage trough, and limit the drainage trough from different directions with the limiting block, which helps to share the load between the first bottom plate limiting block and the limiting groove.

[0017] Preferably, a fixing plate is fixedly provided at the end of the square pile, and the fixing plate is simultaneously attached to the top wall of the prefabricated slot block and the outer floor plate. Reinforcing bolts threadedly connected to the prefabricated slot block or the outer floor plate are penetrated through the fixing plate.

[0018] By adopting the above technical solution, the square piles can be reliably fixed on the top walls of the prefabricated trough blocks and the outer floor panels. Without removing the reinforcing bolts, the square piles, prefabricated trough blocks and the outer floor panels are integrated into a whole, making the drainage trough structure more stable.

[0019] Preferably, the prefabricated slot block is provided with a lifting lug.

[0020] By adopting the above technical solution, it is convenient to lift and apply force to the prefabricated trough blocks during the process of installing and laying the prefabricated trough blocks.

[0021] Preferably, the lifting ear is rotatably arranged on the prefabricated slot block, and the prefabricated slot block is provided with an ear groove, and the lifting ear can be buried in the ear groove.

[0022] By adopting the above technical solution, after the installation and laying of the prefabricated trough blocks are completed, the lifting ears are rotated and buried in the ear grooves, so that the top of the drainage trough remains relatively flat, which helps to avoid the possibility of people tripping due to the ear hanging.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting the outer trench floor, bottom plate, side plate, prefabricated slot block and fitting slot, the damage to the cement layer caused by large load or impact is reduced, the sealing strength of the joint position is improved, and it helps to avoid the occurrence of water seepage;

[0025] 2. By setting the limiting block, limiting groove, rubber layer, first pile groove, second pile groove and square pile, the stability of the connection between the prefabricated slot block and the prefabricated slot is improved, and when a crack appears in one piece of bonding cement, the crack is prevented from spreading to another piece of bonding cement as much as possible;

[0026] 3. By setting fixing plates and reinforcing bolts, the square piles can be securely fixed on the top walls of the prefabricated trough blocks and the outer floor plates. Without removing the reinforcing bolts, the square piles, prefabricated trough blocks and the outer floor plates are integrated as a whole, making the drainage trough structure more stable.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] The present application embodiment discloses a drainage trough for water conservancy projects. Figure 1 and Figure 2 , which includes an outer floor plate 2 and a prefabricated slot block 1. A trench is pre-dug on the ground. Several prefabricated slot blocks 1 are laid in the trench. The end walls of adjacent prefabricated slot blocks 1 are butted against each other. Fitting slots 11 are opened at the outer walls at both ends of the prefabricated slot blocks 1. The outer floor plate 2 is composed of a bottom plate 21 and a side plate 22. The side plates 22 are tilted and fixedly arranged at both ends of the bottom plate 21. The outer floor plate 2 is adapted in shape to a group of adjacent fitting slots 11 and inserted and butted against each other. A limiting block 211 is fixedly arranged on the inner wall of the bottom plate 21 of the outer floor plate 2. A limiting slot 111 is opened on the inner wall of the fitting slot 11. The limiting block 211 can be inserted into the limiting slot 111 and butted against the limiting slot 111. The outer floor plate 2 supports the fitting groove 11 of the adjacent prefabricated slot blocks 1 from the outside, and the limiting block 211 is inserted into the limiting groove 111 and abuts against the limiting groove 111, which limits the bending tendency of the two adjacent prefabricated slot blocks 1 perpendicular to the bottom plate 21. Even without adding any adhesive, the connection between the outer floor plate 2 and the two adjacent prefabricated slot blocks 1 has a certain stability.

[0032] Reference Figure 1 and Figure 2, adhesive cement is applied between the inner surface of the outer floor plate 2 and the fitting groove 11 on both sides of the limiting block 211. Applying the adhesive cement between the fitting groove 11 and the outer floor plate 2 greatly increases the bonding area, thereby improving the bonding strength of the cement and making the cement less likely to crack. At the same time, the adhesive cement is not directly on the surface of the drainage groove, and the impact cannot directly act on the cement, but can only be indirectly transmitted to the cement bonding position. In addition, during the transmission process, the grooves on the ground will play a shock-absorbing role, and a large amount of impact will be shared and absorbed by the ground, greatly reducing the damage of the impact to the cement layer. The limiting block 211 hinders the direct connection of the adhesive cement layers on both sides, and tries to avoid the cracks spreading to the other adhesive cement when a piece of adhesive cement has cracks. The outer surface of the limiting block 211 is covered with a rubber pad, and even if cracks appear on the adhesive cement, the rubber layer seals the liquid that penetrates out. The limiting block 211 is arranged in a terraced shape, which helps the positioning of the limiting block 211 when inserting the limiting groove 111, and tries to avoid the friction between the rubber layer and the inner wall of the limiting groove 111. In summary, the sealing strength of the splicing position is greatly improved, which helps to avoid the occurrence of water seepage.

[0033] In order to further stabilize the gutter structure and improve the stability and sealing strength of the gutter sidewall, refer to Figure 1 and Figure 2 , a first pile groove 112 is provided on both side walls of the fitting groove 11, a second pile groove 221 is provided on the side plate 22, and square piles 3 are inserted into both the first pile groove 112 and the second pile groove 221. After installing the outer floor plate 2 and the prefabricated trough body, the square piles 3 are driven into the first pile groove 112 and the second pile groove 221, which effectively improves the stability and sealing strength of the side wall of the drainage trough. The square piles 3 and the limiting blocks 211 limit the drainage trough from different directions, which helps to share the load between the limiting blocks 211 of the first bottom plate 21 and the limiting groove 111. A fixing plate 31 is fixedly provided at the end of the square pile 3, and the fixing plate 31 is simultaneously attached to the top wall of the prefabricated trough block 1 and the outer floor plate 2, and a reinforcing bolt 32 threadedly connected to the prefabricated trough block 1 or the outer floor plate 2 is provided through the fixing plate 31. The square piles 3 are reliably fixed on the top walls of the prefabricated trough blocks 1 and the outer floor plates 2. Without removing the reinforcing bolts 32, the square piles 3, the prefabricated trough blocks 1 and the outer floor plates 2 are integrated into one, making the drainage trough structure more stable.

[0034] In order to facilitate the lifting and force application of the prefabricated slot block 1, refer to Figure 1 The prefabricated trough block 1 is provided with an ear groove 4, in which a lifting ear 41 is rotatably provided, and the lifting ear 41 can be buried in the ear groove 4. During the installation and laying of the prefabricated trough block 1, the prefabricated trough block 1 can be lifted by the lifting ear 41, so as to facilitate the application of force to the prefabricated trough block 1. After the installation and laying of the prefabricated trough block 1 is completed, the lifting ear 41 is rotated and buried in the ear groove 4, so that the top of the drainage trough remains relatively flat, which helps to avoid the possibility of the ear hanging causing people to trip.

[0035] The implementation principle of a drainage ditch for a water conservancy project in the embodiment of the present application is as follows: the outer floor plate 2 holds the fitting groove 11 of the adjacent prefabricated trough block 1 from the outside, and at the same time, the limiting block 211 is inserted into the limiting groove 111 and abuts against it, effectively preventing the adjacent two prefabricated trough blocks 1 from moving in a direction perpendicular to the bottom plate 21. Even without using an adhesive, the connection between the outer floor plate 2 and the two adjacent prefabricated trough blocks 1 has a certain stability. By applying adhesive cement between the fitting groove 11 and the outer floor plate 2, the bonding area is greatly increased, the bonding strength of the cement is improved, and the risk of cement cracking is reduced. At the same time, the adhesive cement is not directly exposed on the surface of the drainage ditch, so that the impact cannot directly act on the cement, but is indirectly transmitted to the cement bonding position. In this process, the grooves on the ground play a role in eliminating vibration, absorbing most of the impact force, and effectively reducing the damage to the cement layer. The setting of the limiting block 211 hinders the direct connection of the adhesive cement layers on both sides, and minimizes the possibility of the crack propagating to another adhesive cement when a crack appears in one adhesive cement. Thereby improving the sealing strength of the joints and helping to avoid water seepage.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
