Brief discussion of construction controlling essentials for propping box-beams on passenger-carrying special line

Combined with the engineering for propping box-beams from traffic projects in Jing-Jin urban marginal orbits,the paper makes a consideration respectively from bracket's installment,lifting and carrying beams and gravity sand-grout injecting and so on,and then through these consideration,it introduces the essentials of box-beams propping in construction controlling.Meanwhile,it also points out that bracket box-beams have a advantage with a simple design and construction work-period controlled easily and so on.Which will provide a important reference for other similar construction for box-beams propping.
