Technical Field

The utility model relates to the technical field of building construction, in particular to a recyclable lock catch steel casing for deep mucky soil.

Background

A large amount of soft plastic powdery clay is distributed on the shallow part of the lake and marsh facies plain area, and the thickness of the layer is about 2-3 m; most of the silt or silty clay is accumulated by sea, the layer thickness change is large, generally about 4-13m, and the local area can reach 43 m; particularly in the sections with water accumulated all the year round such as rivers, fish and shrimp ponds and the like, the geological conditions are worse. Meet this stratum and can lengthen whole steel in the construction of bridge pile foundation usually and protect a section of thick bamboo or at steel and protect a section of thick bamboo and add the circular steel form of cover, but the effect is all not good, often can appear collapsing hole, reaming and scurrying the hole even, and a large amount of concrete runs off, and pile head concrete placement can not come up, is forced to beat after the stake is formed and establishes the cofferdam and connect the stake, and the cost of connecting the stake is great and the quality is difficult to guarantee. The integral steel casing for traditional pile foundation construction has the following problems: the soil layer is driven too shallow to be effective; when the pile is driven too deep, a vibration hammer is used for driving and lifting, but when the pile is lifted, the concrete still flows outwards or the sludge is squeezed away to cause hole expansion, and the concrete on the pile top sinks; the concrete is initially set too late after the lifting, and the pile foundation initial set concrete is vibrated and cracked to cause pile breakage if the steel casing is not pulled.
