Description

Technical Field

[0001] This utility model relates to a leak-proof device for drainage ditches in water conservancy projects. Background Technology

[0002] Precast prefabricated drainage ditches are commonly used in water conservancy projects, road drainage, and farmland irrigation. Traditional construction methods typically involve directly hoisting precast ditch components into the excavated pit, and then filling the joints between the precast components and the gaps between the precast components and the pit walls.

[0003] This traditional method has many drawbacks: First, the precast components of the trench (especially precast concrete components) are quite heavy. When placed directly at the bottom of the pit, uneven bottom support may cause the precast components to crack due to stress concentration. Second, the treatment of the joints between precast components is crucial for preventing leakage. Traditional methods often involve external grouting, resulting in poor sealing. Furthermore, the construction quality is highly dependent on the skill level of the workers, which can easily create leakage paths.

[0004] Therefore, there is an urgent need in this field for a leak-proof device for drainage ditches in water conservancy projects that can provide stable support, effective guidance, and integrate efficient leak-proof treatment functions. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a leak-proof device for drainage ditches in water conservancy projects that can provide stable support, effective guidance, and integrate efficient leak-proof treatment functions.

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

[0007] A leak-proof device for drainage ditches in water conservancy projects, comprising:

[0008] The connector is provided in multiple ways, and the multiple connectors are installed at intervals in the trench foundation pit. Two adjacent trench prefabricated parts are joined together on the inner side of the connector.

[0009] An adjustable support is installed at the bottom of the connector. When the adjustable support is lowered, it acts on the bottom of the trench pit to improve the load-bearing capacity of the connector.

[0010] The fasteners are installed on both sides of the top of the connector and are used to fix the precast ditch components.

[0011] Preferably, the two ends of the connector are bent to form a support portion, which is supported on the ground, so that the bottom of the connector is suspended in the air.

[0012] Preferably, a grouting groove is machined on the inner wall of the connector, and both ends of the grouting groove penetrate the support portion.

[0013] Preferably, the adjustable support includes a base plate and a vertical plate, the vertical plates are symmetrically arranged on both sides of the base plate, a mounting plate is provided at the bottom of the connector, the surface of the mounting plate is machined with a groove, and a fastener is installed between the vertical plate and the mounting plate, the fastener passing through the groove.

[0014] Preferably, the fastener is a bolt.

[0015] Preferably, a hollow groove is machined at the center of the base plate.

[0016] Preferably, the fixing member is a screw, and screw holes are machined on the top of the support part at both sides of the grouting groove. The fixing member is screwed into the screw holes so that the end of the screw acts on the top of the ditch precast part.

[0017] The beneficial effects of this utility model are:

[0018] Stable support to prevent damage: Adjustable supports provide a solid and reliable bottom support for the connectors and upper precast trench components, with strong load-bearing capacity. This effectively avoids problems such as subsidence and cracking of precast components caused by uneven foundations or insufficient load-bearing capacity, extending the service life of the trench. Superior leak-proof performance: The innovative grouting groove design transforms traditional "external filling" into "internal pressure grouting." The grout fills all voids within the joint and solidifies under pressure, forming a continuous, complete, and high-strength internal seal, fundamentally eliminating the risk of leakage at the joint. The leak-proof effect far surpasses traditional methods.

[0019] Integration and Guiding Positioning: The connector simultaneously serves as a supporting frame, joint template, and grouting channel. During installation, the connector itself provides accurate guidance and positioning for the precast ditch components, ensuring straightness and uniformity of the joints, thus improving construction precision.

[0020] Convenient construction and significantly improved efficiency: This device integrates multiple steps such as leveling, supporting, positioning, fixing, and sealing. Adjustable supports can quickly adapt to different pit depths, simplifying the leveling process. Pre-set grouting channels make subsequent grouting operations simple and efficient, eliminating the need for complex formwork, significantly shortening the construction period, reducing reliance on skilled workers, and saving labor costs.

[0021] Simple structure and strong applicability: The device has a simple structure, low manufacturing cost, and is sturdy and durable. Attached Figure Description

[0031] See Figure 1 and Figure 2 The leak-proof device for drainage ditches in water conservancy projects shown includes:

[0032] Connector 1, multiple connectors 1 are provided, and multiple connectors 1 are installed at intervals in the trench foundation pit 4, and two adjacent trench prefabricated parts 5 are joined together on the inner side of connector 1;

[0033] Adjustable support 2 is installed at the bottom of connector 1. When adjusted downward, the adjustable support 2 acts on the bottom of the trench pit 4 to improve the bearing capacity of connector 1.

[0034] Fixing member 3 is installed on both sides of the top of the connector 1 and is used to fix the prefabricated ditch component 5.

[0035] In the above technical solution, the connector 1 is custom-made according to the pre-installed ditch prefabricated component 5. Common shapes include U-shape and trapezoidal shape. The connector 1 is made of galvanized steel plate and is formed into a predetermined shape by bending. In this embodiment, see [reference needed]. Figure 3 As shown, the connector is trapezoidal.

[0036] The adjustable support 2 provides bottom support for the connector 1. This is especially important for precast concrete trench components, which are relatively heavy. The use of the adjustable support 2 can prevent deformation of the connector 1.

[0037] See Figure 3 As shown, the two ends of the connector 1 are bent to form a support part 101, which is supported on the ground. Under the support of the support part 101, the bottom of the connector 1 is suspended in the air.

[0038] In the above technical solution, the support part 101 formed by bending the two ends of the connector 1 can be supported on the ground on both sides of the top of the ditch when the connector 1 is buried, thus completing the pre-support.

[0039] After the above installation is completed, adjust the adjustable support 2 until it contacts the bottom of the pit.

[0040] See Figure 3 As shown, a grouting groove 102 is machined on the inner wall of the connector 1, and both ends of the grouting groove 102 penetrate the support part 101.

[0041] Grouting groove 102 can be grouted after the precast ditch component 5 is installed, forming a grouting seal at the connection position of adjacent precast ditch components 5.

[0042] The two ends of the grouting groove 102 pass through the support part 101, so that after the precast ditch part 5 is installed, there is a grouting port to facilitate the injection of concrete grout.

[0043] See Figure 3 As shown, the adjustable support 2 includes a base plate 21 and a vertical plate 22. The vertical plate 22 is symmetrically arranged on both sides of the base plate 21. An mounting plate 103 is provided at the bottom of the connector 1. A groove 104 is machined on the surface of the mounting plate 103. A fastener 23 is installed between the vertical plate 22 and the mounting plate 103. The fastener 23 passes through the groove 104.

[0044] In the above technical solution, the bottom plate 21 is supported by the bottom of the trench pit, and the vertical plate 22 is used for assembly with the mounting plate 103.

[0045] Fastener 23 can slide along the groove 104 to accommodate the installation needs of trenches and pits of different depths.

[0046] The fastener 23 is a bolt.

[0047] See Figure 3 As shown, a hollow groove 24 is machined at the middle position of the base plate 21.

[0048] If there is a need to fix the base plate 21 by pouring concrete, the base plate 21 can be pre-poured at the bottom of the trench pit 4. The concrete used for pouring can fill the hollow groove 24 to achieve effective pouring and fixing of the base plate 21.

[0049] See Figure 3 As shown, the fixing member 3 is a screw. Screw holes 105 are machined on the top of the support part 101 and on both sides of the grouting groove 102. The fixing member 3 is screwed into the screw holes 105 so that the end of the screw acts on the top of the ditch precast part 5.

[0050] The precast ditch component 5 can be fixed by simply screwing down the fastener 3. This fixing method is mainly for subsequent grouting construction.

[0051] The installation method for the prefabricated ditch component 5 using this device is as follows:

[0052] The first step is to compact the trench foundation pit to ensure the stability of the inner wall of the pit.

[0053] The second step is to loosen the fasteners 23 to allow the height of the base plate 21 to be adjusted up and down, determine the installation position of the connector 1, and install the connector 1 in the pit. The connector 1 is supported by the support part 101 on both sides of the top of the trench pit 4. The base plate 21 falls naturally under gravity and contacts the bottom of the trench pit 4. The height of the vertical plate 22 is locked using the fasteners 23. If the bottom of the pit is uneven, it is leveled using a level instrument, or the height of the connector 1 is adjusted individually until adjacent connectors are at the same height.

[0054] The third step is to simply pour concrete to fix the base plate 21, so that the position of the base plate 21 remains stable, thereby completing the stable support for the connector 1.

[0055] The fourth step is to hoist the precast ditch component 5. Both ends of each precast ditch component 5 are supported by the connector 1. It is necessary to apply sealant to the inner wall of the connector 1 on both sides of the grouting groove 102 before lowering the precast ditch component 5. The joints of adjacent precast ditch components 5 correspond to the grouting groove 102.

[0056] The fifth step is to seal the joints of the adjacent precast ditch components 5 with sealant and wait for the sealant to harden.

[0057] The sixth step is to inject grout through the grouting groove 102 until the grout overflows from the upper end of the grouting groove 102, and then wait for the grout to harden.

[0058] Step 7: After the above operations are completed, since the precast ditch component 5 is supported by the connector 1, a gap remains between the precast ditch component 5 and the inner wall of the ditch pit. If concrete precast ditch components are used, this gap is filled by methods such as sand filling. If plastic precast components are used, grouting is required at the gaps to ensure durability.
