Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of twist king block installation, in particular to a twist king block regular placement limiting control device and construction method. BACKGROUND

[0002] The twist king block is a kind of prefabricated concrete component commonly used in embankment protection engineering, wharf construction and other fields. Its unique shape design makes it have significant advantages in resisting ocean power such as waves and tidal currents. In embankment protection, twist king blocks are connected and embedded into a whole by mutual interlocking, which can effectively disperse the energy of waves and reduce the impact of waves on the embankment, thereby protecting the embankment from wave erosion and damage.

[0003] The construction type of twist king block is usually irregular and random placement. According to domestic engineering practice and related research, regular placement can be used above the slope shoulder platform. Related research results show that under the action of waves, the block stability is better when placed regularly, and there is a good landscape effect.

[0004] The polar coordinate method commonly used in traditional construction has significant technical limitations: first, when the block centroid coordinates are calculated for on-site lofting, the centroid mark can only provide a rough positioning reference, and the natural swing during block hoisting can easily cause actual placement deviation; second, when manually adjusting the gap between blocks, the operation is highly subjective, making it difficult to achieve the tight interlocking required by the design, directly affecting installation accuracy and efficiency; third, the cumulative effect of individual installation errors can disrupt the overall arrangement order, making it difficult to meet the design specification density standard and thus weakening the landscape coordination; fourth, repeated adjustment of the placement position can easily cause deformation of the cushion structure, forming a vicious cycle of "deviation-adjustment-re-deviation"; fifth, improper control of hoisting angle and position can easily cause block damage due to collision, and after repair, not only there are color difference defects, but also the project cost is increased; sixth, there is a lack of quantitative planar error calculation mechanism, and construction data cannot be traced, making it difficult to achieve fine management and control.
