Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel tube concrete arch bridge construction, in particular to a device for collecting pressurized concrete in an arch of a steel tube concrete arch bridge. Background Art
[0002] After the arch ribs of a top-decker steel tube concrete arch bridge are installed, they need to be grouted with self-compacting concrete. Because all the pipe openings of the arch ribs are welded and sealed, grouting holes must be opened at the top of the arch ribs to ensure compaction. Conventionally, overflowing concrete after grouted concrete injection does not need to be collected and treated. However, when the lower part of the arch bridge is located in a water source protection area, it poses a pollution risk. Therefore, the collection of overflowing concrete after grouted concrete injection needs to be further improved to ensure that the water resources and environment are not polluted.
[0003] To this end, the utility model proposes a device for collecting pressurized concrete in a steel tube concrete arch bridge, which is used to solve the problem of pollution caused by overflow from the top of the concrete pouring in the arch rib. Utility Model Content
