A concrete mixer for submarine tunnel engineering

Abstract

The invention discloses a subsea tunnel engineering concrete mixer. A rotating cavity is formed in a machine body, a front driving device is arranged on the right end of the rotating cavity, a stirring device is arranged in the middle of the rotating cavity, a pouring device is arranged on the left side of the rotating cavity, a rear driving device is arranged on the left end of the rotating cavity, the rear driving device and the front driving device provide power, and diving or ascending power is provided for the mixer. Equipment capable of diving to the seabed is adopted, the concrete construction problem of the seabed high-pressure environment is solved, through the piston moving manner, the concrete is poured, through cooperative use of a ball valve, positioned pouring under the seabed high-pressure environment is achieved, seawater backflow can be prevented, through the driving devices, diving and ascending can be carried out, moving to the designated work area is achieved, and the subsea tunnel engineering can be subjected to concrete moving pouring.

Description

technical field [0001] The invention relates to the field of subsea tunnel construction equipment, in particular to a concrete mixer for subsea tunnel engineering. Background technique [0002] With the continuous advancement of science and technology, the number of means of transportation continues to increase. The original transportation hub has been difficult to meet the needs of people. The construction of cross-sea transportation roads includes bridges and tunnels. Traditional bridge construction is difficult and costly. The construction of subsea tunnels can save a lot of cost. However, due to the difficulty of subsea construction, although the existing immersed tube technology can be implemented, a large amount of concrete needs to be poured on the surface of the immersed tube. Due to the high subsea water pressure, the construction of existing equipment is relatively slow , spent a lot of manpower and material resources, in order to improve the rate of pouring concre...

[0002] With the continuous advancement of science and technology, the number of means of transportation continues to increase. The original transportation hub has been difficult to meet the needs of people. The construction of cross-sea transportation roads includes bridges and tunnels. Traditional bridge construction is difficult and costly. The construction of subsea tunnels can save a lot of cost. However, due to the difficulty of subsea construction, although the existing immersed tube technology can be implemented, a large amount of concrete needs to be poured on the surface of the immersed tube. Due to the high subsea water pressure, the construction of existing equipment is relatively slow , spent a lot of manpower and material resources, in order to increase the rate of pouring concrete, save a lot of cost, it is necessary to invent a kind of anti-high pressure subsea tunnel engineering concrete mixer, the invention can complete automatic mixing and automatic pouring, solve the above problems
