Technical Field
The utility model belongs to simple and easy platform truck die carrier field, in particular to two lining knots in subway station encircle simple and easy platform truck die carrier.
Background
The simple lining trolley is generally designed into a steel arch frame type, uses a standard combined steel template, can be dragged by external power without automatically walking, and is manually operated to remove the vertical template, so that the labor intensity is high. The lining trolley is generally used for short tunnel construction, and particularly has more obvious advantages for tunnel concrete lining construction with complex plane and space geometric shapes, frequent procedure conversion and strict process requirements. Some simple lining trolleys also adopt an integral steel template, but the demoulding vertical mould still adopts a screw rod jack and does not automatically walk, and the trolleys are generally filled by adopting a concrete conveying pump truck. The simple lining trolley generally adopts a combined steel template which is generally made of a thin plate, and the rigidity of the steel template is considered in the design process, so the truss spacing of the steel arch frame is not suitable to be too large. And the longitudinal joint of the steel template is arranged between the trusses so as to be convenient for installing the template fastener and the template hook. If a delivery pump is used for pouring, the pouring speed is not suitable to be too high, otherwise the combined steel template is deformed, and especially when the lining thickness is more than 500 mm, the pouring speed is slowed down. The care should be doubled during the top sealing pouring, the pouring condition of the concrete should be noticed at any time, the concrete is prevented from being poured forcibly after being filled, otherwise, the mold is exploded or the trolley is deformed and damaged.
Although the simple and easy platform truck of tradition, application scope is wide, the complexity in current construction tunnel, the whole size in tunnel often all is random, this has just led to when the tunnel wall need pour cement will need not unidimensional platform truck, and the outline of traditional platform truck all is that a monoblock steel sheet die-casting forms basically, can not recycle moreover, so the cost is high, extravagant very big.
