The invention relates to the technical field of continuous wall construction, and discloses a device for eliminating gaps in the continuous wall by using the self-weight of concrete, including a support frame, a mixing plate is movably connected inside the support frame, and a rotating shaft is movably connected to the bottom of the mixing plate. The bottom of the rotating shaft is movably connected with a fixed part, the surface of the rotating shaft is movably connected with a homogenizing plate, the inside of the homogenizing plate is movably connected with a gear, the inside of the gear is movably connected with a scroll spring, and the surface of the scroll spring is movably connected with a wired roller . Accumulation here is beneficial to the homogenization of concrete in the later stage; the concrete flowing out from the surface of the mixing plate will flow to the surface of the homogenizing plate, so the rotation speed of the gear on the surface of the rotating shaft becomes faster, due to the action of the vortex spring, and the homogenizing plate The number of concrete is multiple, so the flowing concrete will accumulate first and then flow down the surface of the homogenizing plate, and each accumulation will give the concrete a certain speed, so as to achieve the effect of using the concrete weight to pass into the concrete layer by layer to eliminate the void.
