Description
Technical field
The present invention relates to a kind of job practices and concrete-spouting plant of concrete-filled steel tubes arch bridge, relate in particular to concrete into steel pipe of steel pipe concrete arch ring method for filling and device for casting.
Background technology
Concrete filled steel tube is the combined material that fill concrete forms in steel pipe.Stability, corrosion stability and durability when steel pipe improves the steel pipe walls pressurized by concrete filled.Concrete then by the cuff effect of steel pipe walls, has improved concrete compressive strength and ductility, and steel and concrete are organically combined; Aspect construction, concrete filled steel tube can utilize hollow steel pipe as stiff skeleton and template, and construction hoisting is in light weight, and progress is fast, and the construction steel using amount is economized.Because the superiority on material and job practices is very rational with this structure applications in the arch bridge based on pressurized.Because concrete filled steel tube has above-mentioned advantage, the concrete-filled steel tubes arch bridge development in recent years is very fast, is widely used in the highway bridge, and present maximum span has reached 492m.
In the construction of concrete-filled steel tubes arch bridge, concrete perfusion in the main chord tube that constitutes steel pipe concrete arch rib, past employing following two kinds of methods are arranged:

Less when the main chord tube caliber, when main chord tube pipe inner concrete quantity is little, adopt this method more.This method is at arch springing the grouting mouth to be set, and emits the slurry mouth in the vault setting, finishes the concrete spouting construction of a main chord tube from the arch springing to the vault incessantly.Through the pipe inner concrete good integrity of this method perfusion, construction speed is fast, but the only suitable less occasion of main chord tube caliber of this method, when the main chord tube caliber is big, pipe inner concrete quantity is big, when arch camber is higher, just can't be used.
Two, divide repeatedly perfusion of storehouse
Big or perfusion equipment ability too hour adopts this method perfusion usually when the main chord tube caliber.This method is that main chord tube is separated into some sections (storehouse) with diaphragm, according to loading procedure, by storehouse (not necessarily adjacent storehouse) intrusion pipe inner concrete.This method to have an equipment needed thereby simple and can satisfy the characteristics of various execution conditions needs.But there is following defective shortcoming in this method: after a storehouse inner concrete intensity will arrive 70%, just can carry out next storehouse concrete spouting, can not construct continuously, thereby the construction period be longer; At the diaphragm place, the pipe inner concrete is separated, concrete in addition contraction, and slight gap may appear in the diaphragm both sides.Therefore, adopt pipe inner concrete continuity, the globality of this method perfusion all relatively poor.
Summary of the invention
One of technical problem to be solved by this invention provides a kind of concrete into steel pipe of steel pipe concrete arch ring method for filling, this method for filling can satisfy the requirement of construction continuously of major diameter main chord tube concrete spouting well, and shortens the construction period of concrete filled steel tube arch ring effectively.
For solving this technical problem, the technical solution adopted in the present invention is: concrete into steel pipe of steel pipe concrete arch ring method for filling of the present invention, comprise the steps: that a. divides the perfusion section, partly stride steel pipe on a main chord tube left side that constitutes steel pipe concrete arch rib, right partly striding respectively marks off the perfusion section that two-stage at least has certain height difference each other on the steel pipe; B. lay device for casting, device for casting is set respectively in starting points of pouring into section at different levels; C. concrete perfusion is partly striden steel pipe, the right side by device for casting step by step left from arch springing to the vault at main chord tube two ends and is partly striden continous pouring concrete in the steel pipe.
After taking technique scheme, because the main chord tube classification is regardless of the storehouse, the continous pouring step by step from arch springing to vault, a gas is finished the pipe inner concrete perfusion work of a main chord tube, main chord tube pipe inner concrete continuity, good integrity, thus guarantee the quality of concrete-filled steel tube arch.In addition, owing to adopt classification relay reperfusion mode, the pressure altitude of concrete pumping and difficulty, and overcritical to concrete performance, all the perfusion in existing whole storehouse has significantly and reduces.Therefore, method for filling of the present invention can satisfy the requirement of construction continuously of major diameter main chord tube concrete spouting well, and shortens the construction period of concrete filled steel tube arch ring effectively.
Another technical problem to be solved by this invention provides a kind of device for casting that is applied to above-mentioned concrete into steel pipe of steel pipe concrete arch ring method for filling.
For solving this technical problem, the technical solution adopted in the present invention is: device for casting of the present invention, comprise delivery pump, carrier pipe and intrusion pipe, the port of export of intrusion pipe is connected with main chord tube, it is characterized in that: described intrusion pipe place is provided with the slurry that emits that matches with it and manages, and the control sluice valve system that intrusion pipe is changed between plasma discharge, two kinds of duties of perfusion.It is simple and can satisfy the characteristics of various execution conditions needs that device for casting of the present invention has an equipment needed thereby.
