Description

Technical Field

[0001] The invention relates to the field of protective equipment, and in particular to a vertical shaft combined casing structure and method. Background Art

[0002] A shaft project refers to a project for deep underground excavation along a vertical axis. The construction of a shaft project aims to achieve underground resource exploitation, underground facility construction, etc. Due to the large excavation depth of the shaft project, the high confining pressure of groundwater and rock, and a series of other complex underground engineering environmental problems, the construction and safety support engineering of the shaft project is very important.

[0003] The casing of the shaft project is to protect the equipment and personnel inside the shaft. Common materials for casing are reinforced concrete, steel plate and plastic. When selecting the casing material, it is necessary to comprehensively consider the weight, pressure resistance and corrosion resistance of the casing.

[0004] After the shaft is excavated to a certain depth, permanent support work should be carried out in time. In order to ensure construction safety, temporary support is often used during the excavation process to maintain the rock wall and ensure the safety of the working face. Common temporary support forms include temporary support of the shaft ring back plate, temporary support of anchor spraying, metal shield tube support, etc. Common permanent support forms include cast-in-place concrete support and shotcrete support.

[0005] Prior art, for example, an invention patent for a double casing structure for a vertical shaft, application number: 202310633184.4. After the locating pin is inserted into the interior of the limit groove, the first joint tube and the second joint tube are welded and spliced ​​by using the position of the welding hole inside the first joint tube, so as to facilitate the forming of the inner casing and the subsequent hammering construction. After the outer casing sinks, the verticality of the inner casing can be effectively guaranteed by the guiding action of the inner lining ribs and guide grooves in conjunction with the guide rollers, so that the friction resistance when the inner casing is lowered is smaller, and it is easier to sink the inner casing, thereby ensuring the verticality of the pile body after pouring, and effectively ensuring the quality of the pile.
