Description
Technical Field
The invention relates to the field of pier pile top construction, in particular to an assembled pier pile top construction method.
Background
The high pile wharf structure is one of the main types of harbor hydraulic buildings, is quite common in application, has the characteristics of multiple component types, large construction quantity on water, long construction period and the like, and is particularly suitable for adopting an assembled structure. Prefabrication and assembly have become a trend, and not only have the applications gradually started in the bridge construction field, but also the prefabrication and assembly gradually started to replace a cast-in-place construction method in the wharf construction. The bridge is mainly constructed along the longitudinal bridge direction, and the bridge girder erection machine is adopted to construct the bridge span by span along the longitudinal bridge direction, so that the problem of erecting the prefabricated components can be well solved. However, the wharf is different from a bridge, more planar prefabricated parts are provided, and the space for the bridge girder erection machine to stand is small or even not. In order to solve the problem of erection of prefabricated components of a wharf, improve the construction efficiency, reduce the influence on the surrounding environment, reduce the labor investment, reduce the construction risk, ensure the construction quality, and urgently need large-scale integrated construction equipment capable of meeting the requirements.
The construction of the fabricated wharf generally adopts four engineering equipment such as a floating crane ship, a lifting platform, a crawler crane, a construction platform, a crawler crane and a bridge girder erection machine. Floating vessels are most conventional. Overseas projects are also commonly applied by adopting a crawler crane and a refuted organization floating crane due to the lack of a large crane ship, but are greatly influenced by severe sea conditions, so that the method is difficult to adapt to offshore wharf construction of the open sea, such as the floating ship construction considered at the beginning of a bucky Hu Bu wharf, and the construction method is finally abandoned under medium-long period waves. The jacking platform can separate the platform main part from the surface of water, avoids the influence of adverse sea conditions during operation, and the crawler crane on the platform can realize high accuracy hoist and mount, but still need look for the construction window period under its shift operating mode, and pier engineering shoreline is longer, and whole construction shift times is more, and its landing leg length is limited simultaneously, also is difficult to adapt to the pier construction of deep water deep weak stratum.
