Elastic inner wall anti-clogging concrete high-pressure delivery pump pipe and its application method

Abstract

The invention discloses an elastic-inner-wall anti-plugging concrete high-pressure delivery pump pipe and an application method thereof. The pump pipe comprises an outer sleeve, an inner sleeve arranged in the outer sleeve, a plurality of elastic supports and an oil injecting nozzle. The inner sleeve is made from closely-winding spiral pipes, a gap is formed between the inner sleeve and the outer sleeve so that an annular cavity can be formed between the inner sleeve and the outer sleeve, and the two ends of the inner sleeve are connected with the two ends of the outer sleeve in a sealed mode; the multiple elastic supports are arranged between the inner sleeve and the outer sleeve in the axial direction so that the annular cavity is divided into a plurality of arc cavities, and an elastic-support oil hole for being communicated with the adjacent two arc cavities is formed in each elastic support; an outlet of the oil injecting nozzle is communicated with the annular cavity. By means of the elastic-inner-wall anti-plugging concrete high-pressure delivery pump pipe and the application method thereof, the occurrence probability of concrete pipe plugging is effectively reduced through self-adaption deformation of the inner sleeve and injection of lubrication media.

Description

technical field [0001] The invention belongs to the technical field of concrete pumping construction, and in particular relates to an elastic inner wall anti-clogging concrete high-pressure delivery pump pipe and a use method thereof, which can be applied to concrete super-high-rise pumping or super-long-distance pumping. Background technique [0002] Super-high and long-distance pumping of concrete has become an indispensable process for concrete construction of super high-rise buildings, subway tunnels and other projects. However, with the continuous increase of pumping height and distance, the difficulty of construction management also increases. When the construction organization is improper or the quality of concrete fluctuates, it is easy to cause concrete pipe plugging. Once the pipe is blocked, it will take a lot of manpower and material resources to clean the pipe, which will bring safety hazards to the construction quality of the concrete structure, and will also c...

However, with the continuous increase of pumping height and distance, the difficulty of construction management also increases. When the construction organization is improper or the quality of concrete fluctuates, it is easy to cause concrete pipe plugging

Once the pipe is blocked, it will take a lot of manpower and material resources to clean the pipe, which will bring safety hazards to the construction quality of the concrete structure, and will also cause delays in the construction period.

Pumping equipment manufacturers and concrete suppliers have devoted a lot of energy to improving equipment and researching and developing concrete, but the problem of concrete pipe plugging has not been well resolved
