[0002] During the construction of the base slab and subgrade support layer of bridge decks on high-speed railway lines, on-site concrete finishing is difficult, resulting in surface flatness that does not meet regulatory requirements and inaccurate elevation control. The top surface structural dimensions are very stringent, which is crucial for fine-tuning the track slab and is one of the most critical aspects of elevation control in high-speed railway projects. If the elevation differs significantly from the design after pouring, appropriate measures must be taken. This is not only time-consuming and labor-intensive, but also significantly increases construction costs and slows down the progress. Similar problems can also occur during the pouring of concrete for other structures, so it is essential to control the concrete elevation and flatness at the source.

The ends of the finishing rod group are respectively hinged to the bottom of the two support seats, and the support seats are provided with movable wheels that can move along the track; the support seats include a boom and a support frame, the movable wheels are provided at the bottom of the support frame, the boom is lifted and slidably mounted on the support frame, and the support frame is provided with a locking member for locking the boom, and the bottom end of the boom is hinged to the corresponding finishing rod. This high-speed rail adjustable ballastless track base plate top surface concrete finishing device has the following deficiencies:

[0004] 1) The method of adjusting the height by twisting the locking piece and then lifting the boom manually or with external force is neither convenient nor safe;

[0005] 2) When used for finishing construction of concrete roadbed, it is easy to move left and right, with poor stability, affecting the construction quality;

[0006] 3) Only sliding is used to collect the dough, and no vibration mechanism is set, so the collecting effect is poor. Utility Model Content
