Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, specifically to an automatic jacking guide pipe device for underwater concrete pouring. Background Technology

[0002] Underwater tremie casting is a common method for concrete pouring. During the pouring process, the tremie pipe should remain embedded in the concrete at all times, with a depth of 3–6 meters. The lifting process should be smooth to ensure a uniform rise in the concrete surface. However, in current engineering projects, concrete pouring is often performed first, with the concrete surface elevation manually determined before the tremie pipe is lifted in sections. After pouring a section of concrete, a measuring rope and hammer are used to judge the concrete surface height by manual judgment or a single ultrasonic detector. After lifting one section of the tremie pipe, it is removed, and then concrete pouring continues. Once this process is complete, the tremie pipe is lifted again, and the second section is removed.

[0003] During construction, this method requires constant monitoring of the relative height between the concrete surface and the bottom of the tremie pipe. The bottom of the tremie pipe must remain 3-6 meters below the concrete surface to prevent quality issues such as broken piles or mud inclusions caused by the bottom of the tremie pipe detaching from the concrete. Since the concrete surface and the bottom of the tremie pipe are not visible, on-site personnel must calculate the height difference between the concrete surface and the bottom of the tremie pipe based on the volume of concrete already poured. The tremie pipe must then be slowly raised while ensuring its bottom remains below the concrete surface.

[0004] However, during actual construction, when controlling the construction quality, it is inevitable that factors such as the lack of proficiency or negligence of on-site personnel may cause the guide pipe to be lifted too quickly, resulting in pile breakage, or the guide pipe to be lifted too slowly, resulting in pipe jamming, which will seriously affect the quality of pile foundation construction and result in high remedial costs.
