Problems solved by technology

[0003] In view of the related technologies mentioned above, the inventor believes that when the high liquid limit soil is compacted with a sheep foot roller, when the bump is pulled out from the soil from the rear of the travel, the newly compacted high liquid limit soil will be loosened, so that Soils with high liquid limit cannot be practically compacted

Embodiment Construction

[0041] Attached to the following Figure 1-6 This application will be described in further detail.

[0042] Since the bumps 200 of the sheep's foot roller are the main rolling parts for the high liquid limit soil, when the bumps 200 are rolled on the high liquid limit soil, "sheep foot pits" will appear on the high liquid limit soil. During the process of the sheep's foot grinding, the bump 200 will be pulled out from the "sheep's foot pit" at the back of the travel, and the process of pulling the bump 200 out of the "sheep's foot pit" will loosen the rear of the "sheep's foot pit" high liquid limit soil, so that the high liquid limit soil cannot be actually compacted.

[0043] To this end, the embodiments of the present application disclose a compaction method for soil filling with high liquid limit. refer to figure 1 , the high liquid limit soil filling compaction method includes the following steps:

[0044]S1: Lay high liquid limit soil, spread the high liquid limit so...

Abstract

The present application relates to a high-liquid-limited soil filling and compaction method, and relates to the technical field of road construction. The high liquid limit soil is rolled; the sheep foot roller includes bumps. In the rolling step, the bumps are extended when the high liquid limit soil is rolled, and the bumps are retracted after the rolling is completed. In the rolling step of the present application, the bumps are extended when the high liquid limit soil is rolled, and the bumps are retracted after the rolling is completed, so that the high liquid limit soil that has just been compacted is not easily loosened by the bumps. Improved compaction of high liquid limit soils.

Description

technical field [0001] The present application relates to the field of road construction, in particular to a compaction method for soil filling with high liquid limit. Background technique [0002] The sheep foot roller is a road roller with many bumps on the drum. Because the bumps are shaped like sheep feet, they are called sheep foot rollers, also known as sheep foot rollers. The shape of the bump includes sheep foot, cylindrical and square column. Due to the high unit pressure of the sheep foot mill, the compaction degree is large, and the sheep foot mill has a tamping effect, so the sheep foot mill is suitable for compacting cohesive soil and gravel layers. Especially for hard clays, the bumps have the function of stirring, kneading and tamping to make the filling uniform. A large number of sheep's foot pits are formed on the soil surface compacted by sheep's feet, which is conducive to the combination of the upper and lower soil layers and avoids the layering of the ...
