Description

A shaftless pump-pushed multi-stage booster relay pumping system for super high-rise concrete pumping

Technical Field

The utility model relates to the technical field of super high-rise pumped concrete pipeline transportation, in particular to a super high-rise pumped concrete shaftless pump-pushing multi-stage booster relay pumping system.

Background Art

With the development of urban construction, the number of super-high-rise buildings is increasing, and the challenge of super-high-rise construction in vertical transportation of building materials is becoming more and more severe. In addition to the concrete mix ratio problem, the technical difficulty of super-high-rise pumping mainly comes from the conveying capacity of concrete pumping equipment and pumping pipelines. When the building height reaches 300 m or even 500 m, the pumping of concrete becomes more and more difficult. In addition, high-strength and high-performance concrete is usually used in the construction of super-high-rise buildings. The increase in the strength of concrete materials also increases the test of the pumping system. If the pumping system is not set up reasonably during the construction process, the pump pipe is very likely to be blocked; or when the pumping pressure does not meet the height requirements, it will cause the project construction to stop and bring high costs. Therefore, the performance of the selected pumping equipment, the layout of the pumping system and the related operating process are particularly important for whether ultra-high-pressure pumping can be achieved.

At present, there are few domestic ultra-high pressure pumping related methods, the pumping system is lacking, the conventional pumping process is imperfect, the concrete pumping is uncontrollable, and it is very easy to have insufficient pumping pressure and pipe blockage during the pumping process during high-rise pumping. In conventional ultra-high-rise construction projects, ultra-high pressure pumps and relay pumping methods are usually used. For example, patent number CN 115680285 A "A Ultra-High Concrete Pumping System and Construction Method" uses ultra-high pressure pump groups to provide huge pressure to pump concrete. In terms of relay pumping methods and devices, patent number CN 111622779 A "A pulse pressure-compensated long-distance concrete delivery device and its use method" arranges a number of pneumatic booster pumps at intervals on the delivery pipeline, and the air outlet pipe of the pneumatic booster pump is connected to the delivery pipeline to compensate for the push pressure lost during the delivery of concrete, so that the concrete pressure in the entire delivery pipeline remains stable, and long-distance concrete delivery is achieved. Patent number CN 103541550 A "A construction pumping system for steel tube concrete in super-high-rise buildings" connects the high-pressure pump through the discharge port and the low-pressure pump through the pouring hose. The two concrete pumps work in relay mode to achieve the purpose of super-high-rise pumping. Although the existing technology has solved some problems of insufficient pressure and relay pumping in high-rise concrete pumping, the following problems still exist: (1) For long-distance and ultra-high-rise pumping, the high-pressure pump has high pressure, high performance and cost, and high performance requirements for adjacent pressure pump pipelines, which increases equipment costs and reduces construction safety; (2) Traditional pressure pumps provide intermittent pumping pressure, which can easily cause blockage of the delivery pipeline; (3) Traditional pressure pumps have large vibrations and noise, which is not conducive to environmental protection; (4) Traditional pressure pumps cannot achieve multi-stage pressurization.
