Device for utilizing dead load of concrete to eliminate gap of continuous wall

Abstract

The invention relates to the technical field of continuous wall constructions and discloses a device for utilizing dead load of concrete to eliminate a gap of a continuous wall. The device comprises asupporting frame. Evenly mixing plates are movably connected into the supporting frame. The bottoms of the evenly mixing plates are movably connected with rotating shafts. The bottoms of the rotatingshafts are movably connected with fixing pieces. The surfaces of the rotating shafts are movably connected with homogenizing plates. The inner portions of the homogenizing plates are movably connected with gears. The inner portions of the gears are movably connected with scroll springs. The surfaces of the scroll springs are movably connected with winding rollers. Accumulation at the position ofthe evenly mixing plates facilitates homogenization of the concrete in a later period; and concrete flowing out from the surfaces of the evenly mixing plates can flow to the surfaces of the homogenizing plates, so that the rotation speed of the gears on the surfaces of the rotating shafts becomes rapider. Due to the action of the scroll springs and the multiple homogenizing plates, the flowing concrete is accumulated firstly and then flows down from the surfaces of the homogenizing plates, each accumulation gives a certain speed to the concrete, and then the effect of utilizing the weight of the concrete to feed the concrete layer by layer so as to eliminate the gap is achieved.

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.
