Abstract: The present disclosure relates to a field of construction engineering, and in particular to a reinforcing structure of a concrete overhead layer before a building expires. The reinforcing structure of the concrete overhead layer includes supporting structures, connecting structures, and metal members; wherein the reinforcing structure is configured to reinforce a concrete floor slab and/or a concrete beam; through holes are disposed on the concrete floor slab; each of the supporting structures passes through each of the through holes and the supporting structures are configured to support the concrete floor slab and/or the concrete beam; and each of the connecting structures is configured to fix each of the supporting structures on each of the metal members; each of the metal members is disposed on each of the through holes.

Abstract: The present invention relates to a reinforcing structure of unexpired concrete building floors used for reinforcing a concrete column, a concrete beam and a concrete floor slab. The structure has: at least one external column each of the at least one external column wrapping around the concrete column; at least one framework each wrapping around the concrete beam; a plurality of brackets fixedly mounted to the lower surface of the concrete floor slab, and a base plate disposed at the bottom of the concrete column, wherein the bottom of each of the at least one external column is fixed to the base plate, the top of each of the at least one external column is fixed to a corresponding one of the at least one framework, and the corresponding framework is fixed to the plurality of brackets along a length direction of the concrete beam.

Abstract: A method for river/lake level regulation and a water conservancy system. The method for level regulation employs a non-closure mode; a water reservoir system is built on one side of a river/lake, water from the river/lake enters into the reservoir system when the water level of the river/lake exceeds a warning water level, and the river/lake is replenished with the water stored in the reservoir system when the water level of the river/lake is unduly low; the conservancy system, which employs the non-closure mode, is built on one side of a river/lake waterway and includes the water reservoir system and a first water passage, the water reservoir system communicates with the river/lake waterway through the first water passage. The method for river/lake level regulation and the water conservancy system realize river/lake level regulation during drought and flood periods without any river/lake closure, so that water resources are control effectively.

Abstract: A building fire escape system, comprising an auxiliary descending device, the auxiliary descending device being a sliding pole (6) or a spiral chute (6?), and at least one refuge chamber, the refuge chamber being a fireproof spatial structure integrated with the building. The inside of the refuge chamber is divided into a first space (2) and a second space (3) by fire partitions (1, 4). The first space (2) communicates with the interior space of the building. The second space (3) communicates with the exterior space of the building. The fire partition (4) is provided with a fireproof door (11) connecting the first space with the second space. Any two neighboring refuge chambers are interconnected. The fire partition is provided with an observation window (12). The first space and the second space are provided with an air supply pipe (14) and an air exhaust pipe (15). Disposed at the top of the refuge chamber is a water tank (16) connected to the fire main pipe (17).
