Description
Technical field
The present invention relates to pumping machine field, particularly a kind of pipe-line system and concrete distributing equipment.
Background technique
Along with the high speed development of Urban Construction in China, city is high-rise, skyscraper also increases year by year fast, and highly more and more higher, and pumping construction difficulty is increasing, to high reliability and the high security of Concrete Pumping Construction technology, be guarantee that the duration is not incured loss through delay and the guarantee of high construction quality.Therefore develop super high pump-conveying technology in tall building, become more and more important.
At present, according to the altitudes of built high building, High Pressure Reinforced Concrete conventional both at home and abroad, ultrahigh pressure delivery line technology comprise following several mode:
One, for the building of 100 to 200 meters of height, belong to general pumping engineering on the middle and senior level, adopt single pump machine to join wall scroll delivery line and construct;
Two, for the building of 200 to 300 meters of height, belong to conventional high-rise pumping engineering, adopt two superpressure pump machines to join two bar pipeline, hydraulic stop valve and back-pressure loop are set in pipeline;
Three, for the building of 300 to 700 meters of height, belong to super high-rise pumping engineering, adopt two superpressure pump machines to join two bar pipeline, also need in addition to join a superpressure pump machine for subsequent use and a spare duct, stop valve and multistage back-pressure trimmer valve are set in pipeline.
Above-mentioned several mode has the following disadvantages:
First; above-mentioned three kinds of piping mode are all that single tube separate unit joined by single pump; be not interconnected each other; and path is longer between pumping equipment to cloth point; if after wherein a pipeline breaks down; carry out changing and keeping in repair as shut down when there is plugging, booster fault, consuming timely oversizely even can therefore cause stopping construction problem.If maintenance and replacing construction long, also can affect engineering pouring quality and progress.
Secondly, above-mentioned several piping mode, profit pipe sewage mortar can not directly recycle and utilize, and can cause the increase of construction cost.Meanwhile, during with water detergent line, due to cannot closed loop recovery and rinsing, be difficult to effectively process sewage.
Again, when pumping height is too high, there is the risk of not opening in the tube-inserted type hydrovalve be arranged in pipeline.
