Description
Technical field
The invention belongs to urban engineering project fields, are related to a kind of underground pile foundation constructing structure, in particular to a kind of subway
The progressive steel pile casting of deep layer more piece of shield protection zone.
Background technique
With China's expanding economy, urban population density is constantly promoted, and Vehicle's quantity is continuously improved per capita, city
The case where pressure of face traffic is increasing, especially morning and evening peak period, bottom surface traffic congestion is increasingly severe.For above-mentioned feelings
Condition, side builds overhead, grade separation to builders on the ground, builds the rail traffics such as subway below ground, forms three-dimensional traffic
Network alleviates the case where going on a journey congestion.
Subway construction needs to need along subway in underground progress shield in order to guarantee the stabilization of hypogee structure
Metro shield protection zone delimited, to ensure construction safety.When the bridge facility of the overhead of ground, grade separation etc., Bridge Pile design
Positioning it is excessively close from metro shield sideline when, according to subway peace comment requirement, it is necessary to constructed using perturbation flowing mode.Using biography
System technique: such as abrasion drill, churning driven, long spire take soil that can be unsatisfactory for requiring.Therefore embedded deep layer steel pile casting is selected to go again
Piling work.Since metro shield depth is deeper, embedded steel pile casting depth is commonly designed generally at 30 meters or more, depth is big, applies
Work difficulty is big, and conventional static pressure can not construct to designed elevation, it is therefore desirable to which merogenesis construction is applied using rotary static pressure method
Work.How merogenesis construction in by each segment rapid abutting joint, and guarantee accurate alignment, guarantee docking high reliability, be ensure apply
Working medium amount and the emphasis for improving construction efficiency.
Summary of the invention
Big it is an object of the invention to require for buried depth of the metro shield protection zone to steel pile casting, traditional steel pile casting buries
