Description

Technical Field

[0001] The present invention belongs to the technical field of building drainage, and more specifically, relates to a split water stop joint and method based on an adjustable duckbill base. Background Art

[0002] A water stop joint is a waterproof device used in building construction, especially in the fields of building construction, mechanical and electrical engineering, and water conservancy. It is installed in the reserved holes in the floor slab or wall. Its main function is to prevent water from leaking through the gap between the pipe and the floor slab or wall, ensuring the waterproof performance of the building structure.

[0003] The traditional method of pre-buried holes in civil engineering has been gradually phased out, and the on-site installation of water stop joints has been increasingly widely used. The traditional method often leads to leakage problems due to reasons such as non-compact reserved holes and shrinkage, while the water stop joint process can effectively solve these problems. The water stop joint is directly fixed on the building formwork and cast in one go with the cast-in-place floor slab surface, avoiding the complex process of secondary hole hanging. At the same time, its overall design effectively prevents dripping and seepage problems, and has the advantages of simple structure, convenient operation, and remarkable effect. However, during the actual construction process, due to inadequate protection measures during floor concreting and formwork removal, the problem of water stop joint damage occurs from time to time. This requires that the water stop joint not only be firmly fixed during installation, but also be closely combined with the floor slab reinforcement to form a whole, while being easy to disassemble and replace, avoiding replacing the entire set of devices due to local damage. In addition, when installing the drainage riser, the verticality and tightness of the riser also need to be considered, avoiding subsequent rectification due to the deviation of the water stop joint and solving possible leakage and water accumulation problems.

[0004] Some of the existing water stop joints ensure that the upper and lower water stop joints are on a vertical line by setting an annular adjustment groove, but the structure is too complex, easy to be damaged during installation and fixation, and has poor economic benefits; some of the through-rib holes are set too high, and there is no way to deal with different diameters of steel bars, unable to ensure the overall verticality of the pipeline; there are also some water stop joints without a water collecting tray, with a high risk of leakage, a single fixing method, unable to guarantee the verticality of the embedded parts, and being easily damaged after fixation, and unable to be widely applied.

[0005] Therefore, there is an urgent need to design a new type of water stop joint that not only meets the construction requirements but also solves the above problems. Summary of the Invention

[0006] In view of the above defects or improvement requirements of the prior art, the present invention provides a split water stop joint based on an adjustable duckbill base and its construction method. Through innovative split design and multi-layer water collection structure, it effectively solves the problems of complex installation, easy leakage and inconvenient maintenance of water stop joints in the prior art. The system adopts detachable water stop rings of different lengths, which can adapt to floors with different slab thicknesses. The double-layer water collection ring design significantly reduces the leakage risk at the interface. The detachable duckbill steel bar protecting feet at the lower part can be adjusted according to the steel bar size to ensure tight combination with the floor slab steel bars, avoiding the side wall damage caused by the difference in steel bar size of traditional water stop joints and enhancing the stability and sealing performance of the system. The eccentric reducer device at the upper part not only effectively controls the embedding deviation and ensures the verticality of the riser pipe, but also simplifies the installation and maintenance process through detachable design, reducing the situation of floor slab chiseling. In addition, the drain mesh holes at the upper interface allow the cleaning of the building seat water accumulation and upper seepage water without disassembling the pipeline, extending the service life of the pipeline. These innovative designs make the present application have significant advantages in pipeline waterproof construction in the fields of building construction, mechanical and electrical engineering, water conservancy, etc., improving the construction efficiency and the reliability of the system.

[0028] S4: Correct the verticality of the upper and lower water pipe interfaces of the upper and lower water stop joints; push the drainage riser into the lower water pipe interface, rotate the outer arc plate and the inner eccentric plate, and correct the verticality of the pipe by eccentric compensation.

10. A construction method of a split water stop joint based on an adjustable duckbill base, characterized in that, The adjustable duckbill base according to any one of claims 1 to 9 is implemented by using a split water stop joint, comprising the following steps: S1: According to the design drawings, determine the floor thickness, water stop specifications, and steel bar diameter; select the length of the split detachable water stop ring (23) according to the floor thickness; select a detachable duckbill pierced steel foot guard (6) of appropriate duckbill size according to the steel bar diameter of the reserved position; use strong PVC glue to fix the first water collecting tray (21) to the water stop base (1), and bond the detachable duckbill pierced steel foot guard (6) to the water stop base (1); fix the second water collecting tray (22) to the outer arc plate (31); S2: Place a horizontal center cross line in the construction area, confirm the installation position of the water stop base (1) and the reinforcing bar insertion position of the detachable duckbill reinforcing bar foot (6) according to the steel bar arrangement diagram; clamp the detachable duckbill reinforcing bar foot (6) on the steel bar; use bolts to fix the water stop base (1) on the top plate template through the bottom corner fixing bolt holes (63), and ensure that the connection hole on the top is aligned with the downpipe interface (5); fill the outer arc plate (31) and the inner eccentric plate (32) with flexible materials for protection, and install a water stop cap on the upper downpipe interface (4) to prevent concrete from entering; S3: pouring concrete, removing the formwork after reaching the design requirements, removing the flexible material filled on the outer arc plate (31) and the inner eccentric plate (32), and installing the rubber guard (35) at the corresponding position, ensuring that the rubber guard (35) fits tightly with the outer arc plate (31) and the inner eccentric plate (32) without any gap; using glue or snap fasteners to ensure that the rubber guard (35) does not move during the installation process; opening the water stop cap, checking whether the inner eccentric plate (32) and the outer arc plate (31) are damaged or contaminated; if there is any problem, clean or replace them in time; S4: correcting the verticality of the upper downpipe interface (4) and the lower downpipe interface (5) of the upper and lower water stop joints; pushing the drainage riser into the lower downpipe interface (5), rotating the outer arc plate (31) and the inner eccentric plate (32), correcting the verticality of the pipe by eccentric compensation, ensuring that the entire drainage riser meets the requirements of national standards, and then using glue or fixing agent to bond all interfaces; S5: Perform a water filling test through the upper and lower water pipe interfaces (4) to observe the leakage of the drainage pipe. If leakage occurs, the rubber mouth guard (35) can be opened through the inspection port to quickly locate and deal with the leakage point; S6: During use, if water accumulates on the floor, the accumulated water and the upper leaking water can be effectively cleaned through the drainage mesh holes (34) on the outer arc plate (31) and the inner eccentric plate (32) without removing the pipeline.
