Description

TECHNICAL FIELD

[0001] The application relates to the technical field of bridge building machines, in particular to a large-section cantilever pouring bridge building machine suitable for bridge construction. BACKGROUND

[0002] The large-section cantilever pouring bridge building machine suitable for bridge construction is a large special-purpose device integrating functions of bearing, pouring and tensioning. The device takes a bridge pier column as a support, realizes segmental pouring of a beam body through a movable hanging basket structure, and can meet the stringent requirements on the length and weight of a segment in large-span bridge construction. The modular design of the device not only facilitates installation and disassembly, but also can flexibly adjust operation parameters according to the structural characteristics of a bridge, effectively shortens the construction period, and guarantees the precision and quality of beam body pouring, and is a core equipment in modern bridge cantilever construction.

[0003] In the process of bridge building, the maintenance of newly poured concrete is crucial, and spraying maintenance water by using the bridge building machine is a key means to maintain the strength of the concrete. The maintenance water is usually collected rainwater or other natural water from the municipal government, which is easy to obtain and has a low cost, and can meet the needs of large-scale maintenance operation. During spraying, the maintenance water needs to uniformly cover the surface of the concrete, and through continuous moisturizing, cracks caused by excessive water loss of the concrete can be avoided, and an appropriate environment for cement hydration reaction can be provided, so as to guarantee the stability and durability of the beam structure.

[0004] When the spraying of maintenance water is not needed, the water in the water storage tank for storing the maintenance water is usually in a static state. Since the maintenance water is taken from a natural water source, microorganisms and minerals contained in the water will gradually change when they are in a static state for a long time. The microorganisms reproduce to form flocculation and continuously accumulate, and the minerals precipitate and adhere to the tank wall to form scale. When the spraying of maintenance water is needed, the flocculation and scale will flow into the pipeline with the water flow, and form blockage at positions such as water pipe bends and small-diameter nozzles, which causes water flow obstruction and unstable spraying pressure, and finally causes the maintenance water to be unable to be smoothly sprayed out, affecting the continuity and uniformity of the concrete maintenance operation.

[0049] When the bridge section needs to be maintained, the water pump 33 is started, the water in the water storage tank 31 is pumped out through the water pump 33, and then is sent into the shunt pipe 35 through the flow guide pipe 34, and finally is sprayed out through the adjustable spray head at the end of the spray pipe 36, so that the water is sprayed on the bridge section, and the spray maintenance of the bridge section is realized.
