Description

Board wall cast-in-place construction technique between a kind of antislide pile stake
Technical field
The invention belongs to Construction of Anti-sliding Pile field, especially relate to board wall cast-in-place construction technique between a kind of antislide pile stake.
Background technology
Between antislide pile stake, board wall refers to the pile plate wall be laid between adjacent two antislide piles, generally in the multiple antislide piles arranged at equal intervals between adjacent two antislide piles.In recent years, between antislide pile stake, the application of board wall in subgrade construction is more and more frequent, particularly in high cutting and high-fill roadbed construction, is widely used.Between traditional antislide pile stake, panel wall construction method is precast assembly method, and between the antislide pile stake of construction molding, board wall is made up of plate between multiple stake of laying from bottom to up, and between stake, plate is prefabricated profiled breast boards.During practice of construction, after antislide pile concrete strength of pile reaches designing requirement, excavate the inter-pile soil body of adjacent two antislide piles, then carry out assembled to plate between prefabricated profiled multiple stake.Thus, adopt traditional precast assembly method to when board wall is constructed between antislide pile stake, work progress comprises following operation from front to back: between antislide pile pore-forming pouring construction, stake, between plate prefabricated, inter-pile soil body excavation, stake, between plate assembled and stake, plate is repaired.
In practice of construction process, adopt traditional precast assembly method to when board wall is constructed between antislide pile stake, there is defect and the deficiency of following two aspects:
