A high -efficiency rammed earth device

Abstract

The invention provides a high-efficiency rammed earth device, which belongs to the technical field of civil construction equipment. It includes a geared motor, a soil pressing plate, a self-tapping soil pressing screw and several backfilling screws. A connecting shaft is fixedly arranged between the output shaft of the geared motor and the self-tapping soil pressing screw, and the soil pressing plate is connected to the connecting shaft by a spline. The backfilling screw is evenly arranged on the lower side of the soil pressing plate in the circumferential direction, the backfilling screw is rotatably connected to a mounting plate, and the mounting plate is rotatably connected to the outer edge of the soil pressing plate. There is a transmission gear ring meshing with each gear; the inner end of the backfilling screw is located outside the upper end of the self-tapping soil pressing screw. The present invention has the advantages of high efficiency.

Description

technical field [0001] The invention belongs to the technical field of civil construction equipment, and relates to a high-efficiency rammed earth device. Background technique [0002] Ramming is an indispensable construction in the construction process. Ramming is the process of making the rammer vibrate up and down continuously and hitting the ground to compact the soil on the ground. Generally, large-scale rammers, namely excavators, are used on construction sites. A rammed earth device with a vibrating structure is installed on the boom of the excavator, and the rammed earth area is adjusted by the walking of the excavator. This vibration type rammed earth device has the following disadvantages: [0003] 1. It is necessary to provide a large downforce (downforce perpendicular to the soil plane), that is, the boom of the excavator needs to exert a large impact force on the ramming device when it goes down, so as to cooperate with the vibration to compact the soil, and the...

Problems solved by technology

[0003] 1. It is necessary to provide a large downforce (downforce vertical to the soil plane), that is, the boom of the excavator needs to exert a large impact force on the rammed earth device when it goes down, so as to tamp the soil with vibration, and energy consumption loud, loud;

[0004] 2. When tamping the soil on the slope surface, the excavator should not exert too much external force on the vertical slope, otherwise it will easily cause the excavator to roll over or back, such as Figure 4 As shown, the effect of soil compaction is poor. In some cases, it is necessary to compact the slope in sections, that is, to make the retaining wall of the slope, and then carry out longitudinal ramming, and gradually complete the compaction of the entire slope. The slope after construction It is in the shape of a ladder and needs to be backfilled and restored. This method has a long construction period and high cost, and the effect of soil compaction due to multiple constructions is not ideal;

[0005] 3. The thickness of the soil layer that can be rammed by the existing rammed earth device is small, and in some cases it needs to be filled and rammed multiple times, and the efficiency is low;

[0006] 4. It is very difficult to construct corners such as wall corners and the outside of the column. Due to the need for excavators and other equipment to exert external force, the operation accuracy cannot be too high, and the effect of manual hand-held operations is not good.
