Description
Technical Field
The utility model relates to an engineering construction technical field, concretely relates to high-efficient shaped steel of retrieving for excavation supporting construction.
Background
Taking a reinforced cement soil supporting structure as an example, the section steel used in the structure should be recycled under certain conditions. The high-efficient recovery of shaped steel can reduce engineering cost. According to measurement and calculation, the cost of the section steel accounts for about 30% of the construction cost of the enclosure project. If the section steel can be efficiently and completely recycled, remarkable economic benefits can be brought. Therefore, it is needed to develop a new scheme for solving the problem that the structural steel used for supporting the foundation pit in the engineering construction is not easy to be recycled by the technicians in the field.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the deficiencies that exist among the above-mentioned prior art, provide a high-efficient shaped steel of retrieving for excavation supporting construction.
In order to achieve the purpose of the utility model, the utility model provides a technical scheme as follows: the utility model provides a high-efficient shaped steel of retrieving for excavation supporting structure, this shaped steel includes pterygoid lamina and web, the pterygoid lamina edge of a wing is provided with the steel pipe with web handing-over department, steel pipe one end sets up to the connection interface, and this connection interface is used for linking to each other with outside high-pressure water pipe, the steel pipe other end is provided with the sealing, and the sealing bottom sets up with the laminating of shaped steel side, the wash port has been seted up on the steel pipe lateral wall.
Furthermore, the steel pipe is welded at the joint of the flange of the wing plate and the web plate according to the vertical direction of the steel pipe, and a fillet weld is formed between the steel pipe and the wing plate.
Further, the connection interface is a threaded interface.
Further, the diameter range of the steel pipe is 1-10 cm.
Based on the technical scheme, compared with the prior art, the utility model have following technical advantage:
the utility model adopts the high-efficiency recovery section steel for the foundation pit supporting structure, solves the problem that the section steel used for foundation pit supporting in the engineering construction is not easy to recover, and a steel pipe is welded at the joint of a flange of a wing plate and a web plate, a drain hole is arranged on the side wall of the steel pipe, and in the section steel recovery stage, the end part of a steel pipe connecting interface is matched and connected with a high-pressure water pipe, and high-pressure water is sprayed out from the drain hole to wet the soil body on the surface of the section steel, so that the section steel is easy to separate from the surrounding soil body, and further the section steel is recovered efficiently; the other end of the steel pipe is provided with a sealing part to prevent water from flowing out of the bottom of the steel pipe, and the bottom end of the sealing part is attached to the side surface of the section steel, so that the resistance of the bottom end of the steel pipe is reduced when the section steel enters the soil, and the steel pipe is more convenient to use; and a fillet weld is formed between the steel pipe and the wing plate, so that the firmness is strong.
