Air suction dredger for road and bridge construction

Abstract

The invention relates to the technical field of air suction dredgers, and discloses an air suction dredger for road and bridge construction. The air suction dredger for road and bridge construction comprises a sludge suction pipe and a high-pressure exhaust fan, the middle of an inner cavity of the sludge suction pipe is fixedly connected with a sludge conveying pipe, and the bottom of the sludge conveying pipe extends to the outer side of the sludge suction pipe. The top of the sludge conveying pipe penetrates through the top of the sludge suction pipe and extends to the outer side of the sludge suction pipe. According to the air suction dredger for road and bridge construction, through the arrangement of a rotating ring and a spiral crushing rod, rotation of a rotating rod can drive a fixing frame fixedly connected with the rotating rod to rotate, rotation of the fixing frame drives the spiral crushing rod connected with the fixing frame to rotate, rotation of the spiral crushing rod can stir silt around the spiral crushing rod, and water and the silt can be evenly mixed; the fluidity of sludge is kept, the suction of the silt is facilitated, and the spiral crushing rod crushes surrounding large-particle gravels and the like in the rotating process, so that the large-particle gravels are prevented from entering the inside of the sludge conveying pipe, the blockage of the sludge conveying pipe is avoided, and the working efficiency of the suction dredger is not influenced.

Description

technical field [0001] The invention relates to the technical field of air dredges, in particular to an air dredge for road and bridge construction. Background technique [0002] With the continuous development of the national economy, bridge construction continues to develop. Bridge engineering refers to the work process of bridge survey, design, construction, maintenance and verification, as well as the science and engineering technology for studying this process. It is a branch of civil engineering. The development of bridge engineering depends mainly on the needs of transportation for it. [0003] In the process of bridge construction, it is necessary to suck out the muddy water at the bottom of the bridge, so as to facilitate the foundation construction at the bottom. The muddy water at the bottom of the bridge is sucked by suction dredgers. The existing air suction dredgers for bridge construction are used in some There are also some shortcomings in the aspect, and fu...
