AI Technical Summary
Existing prefabricated channel water-stop connection structures are inadequate in terms of stability, sealing, and compressive strength, and are prone to misalignment, leakage, and breakage, especially under external forces or water flow impact.
The design employs a combination of concrete limiting blocks, limiting pins, sealing strips, and pre-embedded steel bars. Precise alignment and rigid connection are achieved through bolted connections between the limiting pins and limiting holes. Sealing strips are installed at the joints to improve sealing. Combined with the integrally cast cement drainage channel and the steel reinforcement skeleton of the limiting blocks and pressure blocks, the structural stability and compressive strength are enhanced.
It effectively prevents the cement drainage channel from being misaligned or shifted, reduces the risk of leakage, improves the water-stopping effect of the channel, and enhances the compressive strength of the connection parts and the overall structural bearing capacity.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated channel technology, specifically a prefabricated channel water-stop connection structure. Background Technology
[0002] In existing prefabricated channel water-stop connection structures, the assembly between cement drainage channels usually adopts a simple edge pressing treatment method.
[0003] This connection method has the following significant drawbacks:
[0004] 1. Poor stability: The edge pressing process lacks an effective limiting structure, which makes the connection parts prone to misalignment or displacement. Especially when subjected to external forces or water flow impact, the assembled channel structure is difficult to maintain stability.
[0005] 2. Insufficient sealing: Traditional edge-sealing connections rely on direct contact between concrete sections and lack dedicated sealing components, making them prone to leakage due to loose joints, which affects the water-stopping effect of the channel.
[0006] 3. Low compressive strength: The concrete at the edge is thin and lacks reinforcement, making it prone to fracture under load, which reduces the overall durability and reliability of the structure.
[0007] Therefore, we propose a prefabricated channel waterstop connection structure. Utility Model Content
[0008] (a) Technical problems to be solved
[0009] To address the shortcomings of existing technologies, this utility model provides a prefabricated channel water-stop connection structure, which facilitates the increase of stability and sealing between cement drainage channels after assembly, and also has a certain anti-displacement function, effectively solving the problems in the background technology.
[0010] (II) Technical Solution

The receiving component includes a concrete limiting block, a sealing strip, a limiting pin, a threaded hole, and a first pre-embedded steel bar. The overlapping component includes a concrete pressing block, a second pre-embedded steel bar, a limiting hole, and a bolt head limiting hole. The cement drainage channel, the concrete pressing block, and the concrete limiting block are integrally cast.
[0012] Preferably, the first embedded steel bar is embedded between the front end of the concrete limiting block and the cement drainage channel, and the second embedded steel bar is embedded between the rear end of the concrete pressing block and the cement drainage channel.
[0013] Preferably, the limiting pin is fixedly installed on the left and right ends of the upper outer surface of the concrete limiting block, and the lower end of the limiting pin extends into the interior of the concrete limiting block. The threaded hole is opened on the upper outer surface of the limiting pin, the limiting hole is opened on the left and right sides of the upper outer surface of the concrete pressing block, and the limiting hole extends to the lower outer surface of the concrete pressing block. The bolt head limiting hole is opened at the upper part of the limiting hole.
[0014] Preferably, a bolt is provided between the limiting pin and the limiting hole, the bolt is threaded between the threaded hole and the limiting hole, and the head of the bolt is limited in the bolt head limiting hole.
[0015] Preferably, the upper surface of the concrete limiting block matches the lower surface of the concrete pressing block, so that during splicing, the concrete pressing block can be tightly pressed onto the concrete limiting block and sealed by the sealing strip.
[0016] Preferably, the cement drainage channel, the concrete limiting block and the concrete pressing block have the same concrete grade and are all pre-embedded with a steel reinforcement skeleton.
[0017] Preferably, the depth of the bolt head limiting hole is greater than the thickness of the bolt head.

[0019] (III) Beneficial Effects
[0020] Compared with the prior art, this utility model provides a prefabricated channel water-stop connection structure, which has the following beneficial effects:
[0021] 1. This prefabricated channel water-stop connection structure achieves precise alignment and rigid connection through the cooperation of the receiving components (concrete limiting blocks and limiting pins) and the overlapping components (concrete pressing blocks and limiting holes), effectively preventing the cement drainage channel from misaligning or shifting after assembly. The bolt fastening design further strengthens the connection strength and ensures that the structure remains stable under load or water flow impact.
[0022] 2. This prefabricated channel water-stop connection structure sets a sealing strip between the concrete limiting block and the pressure block, forming a tight waterproof barrier through compression, which significantly reduces the risk of leakage at the joint and improves the water-stopping effect of the channel.
[0023] 3. This prefabricated channel water-stop connection structure, with an integrally cast cement drainage channel, limiting block and pressure block, combined with the internally embedded steel reinforcement skeleton (first and second embedded steel bars), greatly improves the compressive strength of the connection part and the overall structural bearing capacity. The concrete grade is uniform, avoiding stress concentration or cracking problems caused by material differences. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0030] This embodiment is a prefabricated channel waterstop connection structure.
[0031] like Figure 1-4 As shown, the system includes a cement drainage channel 1. An overlapping component 3 is fixedly installed on the outer surface of the rear end of the cement drainage channel 1, and a receiving component 2 is fixedly installed on the outer surface of the front end of the cement drainage channel 1. The receiving component 2 includes a concrete limiting block 4, a sealing strip 5, a limiting pin 6, a threaded hole 7, and a first pre-embedded steel bar 8. The overlapping component 3 includes a concrete pressing block 9, a second pre-embedded steel bar 10, a limiting hole 11, and a bolt head limiting hole 12. The cement drainage channel 1, the concrete pressing block 9, and the concrete limiting block 4 are integrally cast.
[0032] The first embedded steel bar 8 is embedded between the front end of the concrete limiting block 4 and the cement drainage channel 1, and the second embedded steel bar 10 is embedded between the rear end of the concrete pressing block 9 and the cement drainage channel 1; the limiting pin 6 is fixedly installed on the left and right ends of the upper outer surface of the concrete limiting block 4, and the lower end of the limiting pin 6 extends into the interior of the concrete limiting block 4; the threaded hole 7 is opened on the upper outer surface of the limiting pin 6; the limiting hole 11 is opened on the left and right sides of the upper outer surface of the concrete pressing block 9, and the limiting hole 11 penetrates to the lower outer surface of the concrete pressing block 9; the bolt head limiting hole 12 is opened on the upper part of the limiting hole 11; the limiting pin 6 and the limiting hole 11 A bolt is installed between the threaded hole 7 and the limiting hole 11, and the bolt head is limited in the bolt head limiting hole 12. The upper surface of the concrete limiting block 4 matches the lower surface of the concrete pressing block 9, so that the concrete pressing block 9 can be tightly pressed onto the concrete limiting block 4 during splicing, and sealed by the sealing strip 5. The concrete grade of the cement drainage groove 1, the concrete limiting block 4 and the concrete pressing block 9 are the same, and all of them have a steel reinforcement skeleton embedded inside. The depth of the bolt head limiting hole 12 is greater than the thickness of the bolt head. The fitting accuracy of the limiting pin 6 and the limiting hole 11 is an interference fit or a clearance fit.
[0033] It should be noted that this utility model is a prefabricated channel water-stop connection structure. The cement drainage channel 1 described in this article belongs to the prior art. When assembling two sets of cement drainage channels 1 (as shown in the appendix of the instruction manual) Figure 4 As shown, the concrete pressing block 9 of the overlapping component 3 in one set of cement drainage channels 1 overlaps on the concrete limiting block 4 of the receiving component 2 in another set of cement drainage channels 1. The sealing strip 5 is squeezed by the gravity of the cement drainage channels 1, and the sealing strip 5 plays a sealing role. When the two sets of cement drainage channels 1 are assembled, the limiting pin 6 of the cement drainage channel 1 is inserted into the limiting hole 11. Then, the bolt is connected between the limiting hole 11 and the limiting pin 6, and the head of the bolt is limited in the bolt head limiting hole 12, thus completing the assembly. The assembly is stable, and the limiting pin 6 prevents misalignment. The lower end of the limiting pin 6 is pre-embedded in the concrete limiting block 4 before pouring the concrete limiting block 4. The limiting pin 6 and one end of the second pre-embedded steel bar 10 are both pre-embedded in the cement drainage channel 1 before pouring to improve the load resistance.
