Description

Technical Field

[0001] The utility model relates to the technical field of underwater cast-in-place pile construction, in particular to an underwater bored cast-in-place pile construction device. Background Technique

[0002] In the current field of underwater bored cast-in-place pile construction, the installation of the casing is a key link, which is directly related to the quality and safety of subsequent drilling and pouring. Traditional construction methods usually rely on large gantry cranes to lift the casing and adjust its position. For example, the technical solution described in the Chinese utility model patent with the application number 202321623367.X. However, this method has several significant drawbacks.

[0003] First of all, the construction process of the gantry crane is complex and time-consuming. Since it needs to be constructed on the water surface, it involves the construction of a water operation platform, the installation of the gantry crane structure and related stability measures. These works not only require a large amount of engineering materials and manpower, but are also affected by natural conditions such as hydrology and meteorology, increasing the construction difficulty and cost.

[0004] Secondly, after the gantry crane lifts the casing, due to factors such as water surface fluctuations and wind force, the position adjustment of the casing often requires multiple repeated operations, which not only increases the construction time, but may also affect the accuracy and stability of the casing. In addition, the use of large gantry cranes is also limited by the spatial conditions of the construction site, and may not be applicable to some narrow or complex construction environments.

[0005] Therefore, there is an urgent need for a more convenient and efficient underwater bored cast-in-place pile construction device to provide an effective solution to the defects of the existing technology. Content of the Utility Model
