Problems solved by technology
[0003] After the UHPC is paved, it will be leveled by a leveling machine. The surface of the UHPC after the leveling treatment needs to be closed. At this stage, most of the surface closing operations are done manually. Not only is the workload heavy, but the quality of the closing Low, for example, there may be unfinished surfaces at the handover position between workers, and there will be problems such as uneven surface after final setting of UHPC in some places, and substandard flatness.

The invention discloses construction equipment for UHPC paving, and relates to the technical field of UHPCs, the construction equipment comprises a surface finishing system, the surface finishing system comprises a supporting transverse frame located between two supporting bases, each supporting base is provided with a lifting stand column and a lifting motor for driving the lifting stand column to ascend and descend, and the supporting transverse frame is connected with the lifting stand column; the lifting motor drives the lifting stand column to rotate so as to drive the supporting transverse frame to ascend and descend. The noodle collecting system further comprises a plurality of noodle collecting turntables, and the acting surfaces of the adjacent noodle collecting turntables are overlapped; and each dough collecting turntable is fixed with the supporting transverse frame through a transmission shaft, and each transmission shaft rotates through a transmission mechanism. According to the surface finishing system disclosed by the invention, the surface finishing turntable is controlled to rotate to finish the UHPC surface through the surface finishing distance and the accumulated water thickness which are obtained through measurement and calculation, so that the UHPC surface is automatically, accurately and continuously subjected to wiping, pressing and surface finishing; compared with manual surface finishing, the working efficiency is improved, and the surface finishing quality is further remarkably improved.
Description
technical field [0001] The invention relates to the technical field of UHPC (Ultra-High Performance Concrete, ultra-high performance concrete), in particular to a construction equipment for UHPC pavement. Background technique [0002] In recent years, many long-span orthotropic steel bridges in China have experienced fatigue cracking of steel bridge decks, cracking of pavement layers, wrapping, and delamination, which seriously affect the safety of bridge traffic. In order to solve the two world-wide technical problems of steel bridge deck fatigue cracking and pavement damage in long-span steel bridge deck pavement, ultra-high-performance concrete composite bridge deck systems have been gradually popularized and applied, which has great impact on large-area ultra-high-performance bridge decks. Concrete pavement construction puts forward higher requirements. [0003] After the UHPC is paved, it will be leveled by a leveling machine. The surface of the UHPC after the leveling...
