Description

Technical Field

[0001] The invention relates to the technical field of prefabricated box girder casting processing application, in particular to a slurry leakage prevention device used for casting high-speed railway prefabricated box girders. Background Art

[0002] With the rapid advancement of my country's high-speed rail industry, the mileage of newly built high-speed rail lines continues to grow. The high speed, safety and stability of high-speed rail operation rely on high-quality infrastructure construction. Among them, prefabricated box girders, as a key component of high-speed rail bridges, their quality is directly related to the overall performance of high-speed rail. During the casting process of prefabricated box girders, the gaps in the spliced templates are prone to leakage, which will cause defects such as honeycomb surface and holes on the surface of the box girder, seriously affecting the appearance quality and structural strength of the box girder, and thus burying hidden dangers to the durability and safety of high-speed rail bridges. In order to meet the growing demand for high-speed rail construction and ensure that the casting quality of box girders reaches high standards, anti-leakage equipment is usually used to assist the casting of prefabricated box girders.

[0003] However, the existing docking equipment for laying underground pipelines still has great defects when used. The existing anti-leakage slurry equipment for casting high-speed railway prefabricated box girders often adopts traditional sealing materials such as rubber strips and sealants to prevent leakage. These materials are easily displaced or fall off due to the vibration of cement slurry, have low stability, and easily lead to sealing failure. In addition, the existing anti-leakage slurry equipment for casting high-speed railway prefabricated box girders has poor adaptability and flexibility. Not only can it not meet the needs of prefabricated box girders of different sizes and shapes, it can also not seal the template gaps at different positions. In addition, the existing anti-leakage slurry equipment for casting high-speed railway prefabricated box girders has poor accuracy and often requires manual adjustment of the baffle position, which is time-consuming and labor-intensive, and has high labor intensity, resulting in low efficiency in casting prefabricated box girders. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems that the existing anti-leakage slurry equipment used for casting high-speed railway prefabricated box girders often adopts traditional sealing materials such as rubber strips and sealants to prevent leakage.

At the same time, the second hydraulic cylinder drives the flip frame at one end of the second hydraulic rod to move, so that the baffle can prevent leakage of slurry from the template gap at the casting and bending position of the prefabricated box beam, which is conducive to further fine-tuning the inclination angle of the baffle, ensuring that under complex working conditions, the baffle is conducive to accurately forming a seamless seal with the template on the box beam, so that the baffle is conducive to all-round coverage of the gap where leakage may occur, further ensuring that the anti-leakage equipment is more accurate when used.

On the one hand, it is not only conducive to quickly and conveniently completing the position adjustment of the baffle, reducing the adjustment time during the construction process, thereby improving the construction efficiency of the precast box girder, but also reducing the difficulty and workload of manual operation and reducing labor intensity.
