Description

Technical Field

[0001] The utility model relates to the technical field of slipform construction, in particular to a guide trough for pouring concrete in cylinder slipform construction. Background Art

[0002] The construction of the cylinder structure of the silo adopts the slipform construction technology, which not only speeds up the progress but also makes the appearance of the silo more beautiful. However, the concrete must be poured continuously in the slipform construction, and the pouring speed cannot be too slow, so as to avoid the concrete and the formwork being firmly attached over time and causing the formwork to be unable to slide up. At present, in the slipform construction, the concrete is mainly lifted to the slipform platform by a delivery pump or a concrete hopper, and then poured into the formwork one shovel at a time by a manual trolley. The efficiency is low, and the working surface of the slipform platform is narrow, and the operation is not smooth if more manpower and trolleys are invested. Another method is to unload the concrete directly from the delivery pump or concrete hopper into the formwork. Although it can improve efficiency and reduce labor input, the net distance between the formwork and the steel bar is only about 3cm. Due to the obstruction of the steel bar and the slipform gantry, the pump pipe mouth and the hopper mouth cannot be fully aligned with the formwork for pouring, which causes a lot of concrete to fall outside the formwork, resulting in a large waste. At the same time, some leaked cement slurry drips on the lower wall of the silo that has been constructed, which also affects the beauty of the silo.

[0003] After the existing guide trough for pouring concrete in the cylinder slipform construction is used, a lot of concrete will remain on the inner wall of the guide trough. These concretes need to be cleaned manually later, which is not only time-consuming and labor-intensive, but also causes unnecessary loss of concrete. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a guide trough for pouring concrete in a cylinder slipform construction which is simple to operate, saves manpower and has high construction efficiency.
