Problems solved by technology

However, since the cement content in the cement-stabilized crushed stone mixture is generally below 5%, the mixing time in the continuous mixing device is generally within 10s, and it is difficult to mix evenly in such a short time. The amount of cement used in crushed stones generally takes a high limit, which will cause cracks to occur in cement-stabilized crushed stones in practice; if the amount of cement used is too small, the cement content of the local mixture will be too small, and the load-resistant capacity and stability will be reduced, which is prone to cracks. local subsidence phenomenon

Abstract

The invention belongs to the technical field of stirring machines. The invention particularly relates to a vibration stirring durable type cement stabilized macadam device and a construction method thereof, comprising a vertical shaft stirring mechanism and a horizontal shaft stirring mechanism, wherein the first stirring motor and the second stirring motor drive the first and second stirring shafts to rotate respectively, and the vibration motor drives the second stirring shaft to vibrate and stir the materials; The invention also provides a construction method of the device, comprising the following steps: 1, measuring a line of defense, 2, excavating a foundation pit of a mixer, 3, excavating a through track, 4, padding a cushion foundation wall, 5, and pouring concrete. The device of the invention has the advantages of sufficient stirring, high compressive strength of the obtained cement stabilized macadam and good fineness.

Description

technical field [0001] The invention relates to the technical field of mixer research, in particular to a vibration-stirring durable cement-stabilized gravel device and a construction method thereof. Background technique [0002] The vibrating mixer places the vibrating motor at one end of the stirring shaft, drives the shaft to vibrate, and places the vibration source inside the material. With such a structural arrangement, the material can absorb vibration energy more directly, which is conducive to reducing energy waste. In addition, the material is also It can balance the mechanical incongruity caused by some vibrations and improve the durability of the equipment. This exquisite design seeks advantages and avoids disadvantages, and vigorously promotes the industrial process of vibration and stirring. In the vibration mixing technology, the vibrator is designed using the dynamic method, and the concrete buried in the center of the mixing drum is collected so that the sti...
