Problems solved by technology
[0003] In the existing technology, the traditional large-scale gantry crane lifting and rail pushing technology are generally used for the in-field transfer of prefabricated piers. Using this technology requires investment in large-scale equipment, which increases related costs and affects the settlement of the moving track foundation and The requirements for construction accuracy are relatively high (the uneven settlement of the transfer track foundation and construction errors cause the transfer track to be uneven, generally 3-5cm in height difference), which will lead to uneven stress on the prefabricated component concrete), therefore, it is necessary to Improvement on existing technology

Embodiment Construction
[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.
[0031] As shown in the figure, a prefabricated concrete component transfer system includes an on-site transfer reserved passage 130 arranged on a prefabricated pedestal 120. There is a push-slide beam 140 between them, and the push-slide beam 140 is slidingly connected with the prefabricated concrete member 110 (refer to Figure 5 : the push sliding beam 140 is provided with a slide plate 200, the slide plate 200 is slidingly connected with the push slide beam 140, and the precast concrete member 110 is connected with the slide plate 200 through the support beam 230), the slide plate 200 in the present embodiment is an MGE slide plate, The upper end surface section of the support beam 230 is relatively large, and is used to carry ...

The invention discloses a precast concrete construction element transporting system and method. Precast concrete construction elements are moved forward at a pushing slippage beam through a horizontal pushing system; the precast concrete construction elements and the pushing slippage beam are separated through a slippage converting and supporting system; then the pushing slippage beam is moved forward through the horizontal pushing system; at the time, the precast concrete construction elements are positioned at the rear end of the pushing slippage beam; and the concrete construction elements are transported to the required position through repeating the actions above, wherein the pushing slippage beam can be leveled through a cushion block. According to the invention, the problem that the horizontal pushing system is difficult to run because the transporting rail is uneven due to foundation settlement and construction error can be solved; and the transportation of the precast concrete construction elements can be finished by utilizing a pushing slippage beam, the material expense and space are saved, and the precast concrete construction element transporting system and method are convenient to use.
Description
technical field [0001] The invention relates to the technical field of bridge foundation construction, in particular to a prefabricated concrete member transfer system and transfer method. Background technique [0002] In some bridge construction projects in the Lingdingyang sea area, the foundation construction is greatly affected by factors such as monsoons, currents, and waves, and the offshore operation time is limited. The construction technology of "factory prefabrication standardization, on-site installation and assembly" is adopted. The cross section of the prefabricated piers is small (only 12×16m) and heavy (the maximum weight is about 3000t). In the case of using a large crane, how to safely and quickly complete the transfer of the prefabricated piers and abutments in the site is the key to the success of the construction. [0003] In the existing technology, the traditional large-scale gantry crane lifting and rail pushing technology are generally used for the ...
