Description

Technical Field

[0001] This invention relates to the field of frozen soil surface solidification treatment, specifically to a mixing device for frozen soil surface solidification treatment. Background Technology

[0002] In permafrost and cold regions, the rate of road damage is generally above 30%. The main reason is the varying ice content in the seasonally active soil layer. Once a freeze-thaw cycle occurs, coupled with the warming and degradation of permafrost, it inevitably leads to foundation deformation. Furthermore, due to the uneven ice content in permafrost, differential thaw settlement deformation of the foundation is highly likely, subsequently causing roadbed and pavement damage. The geological conditions in permafrost regions are extremely complex, encompassing special geological types such as permafrost, soft soil, and fractured rock layers. This makes constructed roads highly susceptible to various types of damage, with uneven foundation settlement being the core contributing factor, severely impacting the road's traffic quality and service life.

[0003] The general process for solidifying frozen soil pavements is as follows: cleaning the subgrade soil in the area to be solidified, backfilling the subgrade soil mixed with solidifying agent, and compacting and leveling the pavement using a road roller. However, the mixing of solidifying agent and subgrade soil is currently carried out by excavators. The excavator bucket is used to mix the subgrade soil and solidifying agent evenly. However, this mixing method is very slow, and due to the large volume of the excavator bucket, the fineness of the mixing of subgrade soil and solidifying agent during the mixing process is not high.

[0026] Example 2: Please refer to Figure 1 and Figure 2 This embodiment is a further description of the first embodiment. A central actuating element is also provided on the side of the limiting sleeve 1 away from the rotating tube 11. The central actuating element is used to move the mixture of the base soil and the curing agent. The central actuating element is located on the side of the limiting sleeve 1 away from the rotating tube 11. There are two rotating tubes 11 and two central actuating elements, and they are distributed in a circumferential staggered manner.

[0027] The central actuating component includes a frame plate 24, which is fixed to the lower end face of the limiting sleeve 1. Several paddles 25 are also fixedly provided on the lower end face of the frame plate 24.

[0028] The central actuating component includes several curved levers 26, and the curved levers 26 are fixed to the limiting sleeve 1.

[0029] Working principle: After leveling the frozen soil remediation area, 6 is installed in the center of the remediation area. Several pins 7 are inserted into the soil to secure 6. At this time, the rotating tube 11 is installed by inserting the fitting block 13 between the mounting block 12 and the docking slot 14. Then, the hexagonal protrusion 19 is rotated by a wrench. When the threaded column 18 rotates, the threaded sleeve block 20 can move downward, so that the connecting plate 21 and the pin 23 can be inserted into the positioning hole 15. Through the cooperation of the pin 23 and the positioning hole 15, the fitting block 13 can be restricted inside the docking slot 14. When the connecting plate 21 is pressed against the upper end face of the fitting block 13, the continuous movement of the threaded sleeve block 20 can compress the spring 22. Under the reaction force generated by the spring 22, the connection between the threaded sleeve block 20 and the threaded column 18 can be more stable. After the rotating tube 11 is installed, the threaded blades 27 should be kept in contact with the ground. The geared motor 3 is started by the rechargeable power supply 2. When the geared motor 3 is running, it can rotate the rotating tube 11. During the rotation, the rotating tube 11 can transport the base soil and hardener towards the limiting sleeve 1 through the threaded blades 27. During the transport, the base soil and hardener can be mixed. The workers can arrange the base soil and hardener within the rotation radius of the rotating tube 11. The base soil and hardener piled around the limiting sleeve 1 can be moved by the paddle 25 or the curved paddle 26, thereby assisting the threaded blades 27 in mixing the base soil and hardener, improving the uniformity of the mixture. Compared with mixing the base soil and hardener by the excavator bucket, the mixing efficiency is higher and the mixing uniformity is better.
