A device for eliminating gaps in continuous walls by using concrete self-weight

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of diaphragm wall construction, in particular to a device for eliminating gaps in a diaphragm wall by using the self-weight of concrete. Background technique [0002] Diaphragm wall, also known as underground diaphragm wall, is a kind of grooving machine used in foundation engineering on the ground. The manufacturing process is to excavate a long and narrow deep groove along the peripheral axis of deep excavation project under the condition of mud retaining wall. Afterwards, the reinforcement cage is hoisted, and the concrete flow material is passed into it, and cooled and solidified to form an independent unit groove end. [0003] In order to increase the strength of the continuous wall, the structure of the reinforcement cage is relatively complicated. The traditional placement of the reinforcement cage is only to put it into the deep groove, and it cannot be fixed to the deep groove, resulting in the proc...

[0003] In order to increase the strength of the continuous wall, the structure of the steel cage is relatively complicated. The traditional placement of the steel cage is only to put it into the deep groove, and it cannot be fixed to the deep groove, resulting in the process of passing the concrete material. , the impact force of the concrete will move the reinforcement cage, which will lead to the reduction of the strength of the formed continuous wall; in addition, the concrete feeding method in the prior art only uses a number of conduits to pass the concrete into the reinforcement cage, because the concrete has a certain It is viscous and has poor fluidity, which leads to uneven injection of concrete, resulting in voids that affect the quality of the wall. Therefore, a device that uses the weight of concrete to eliminate the voids in the continuous wall came into being.
