609 steel support is a kind of subway steel support, in the field of construction, especially in the subway construction, plays a vital role.About 609 steel support construction technology points are as follows：
(1) pre-loading Jack must be graded loading.
(2) steel cross brace set time must be strictly in accordance with the design of the master, earth excavation should be layered, according to the depth of excavation and excavation time set up steel support.
(3) all support connections, should be close to the pad close to prevent the steel pipe support eccentric pressure.
(4) the end of the ramp in strict accordance with the design size and angle processing welding, installation, to ensure that the support for the axis of force and welding firm.
609 steel support fixed end features: fixed end can flexibly adjust the splicing length of steel support, but also enhance the overall compressive strength of steel support.Mainly applicable to Subway, bridge, large pool, cover digging tunnel and other projects, responsible for on-site construction and installation.The main models: 609 * 200mm, 609 * 300mm, 609 * 500m.
609 steel support active end product features: active end also become active head is one of the steel support components, specifications have Φ800 * 1450, Φ609 * 1450 two.Adjust the length of 0-30cm, tension adjustment for the overall steel support.Active end is a steel support telescopic end, widely used in the construction process of the cover beam bracket, is characterized by a good adjustment of the telescopic distance, the Living End with steel support fixed, no longer have room for activities can be adjusted by soil pressure compaction firm, after the end of the construction structure, removal of steel, the use ofThe active end is also known as the active head is one of the steel support part of the specifications have 800×1450, 1450×two kinds, adjust the length of 0 ~ 30cm, for the whole steel support tension adjustment.
