Embodiment Construction

[0043] The following is attached Figure 1-6 The application is described in further detail.

[0044] The embodiment of the application discloses a lime soil filling construction method. refer to figure 1 , the construction method of lime soil filling includes the following steps:

[0045] S1: Spread the plain soil layer, lay the plain soil on the lower bearing layer, and use a light roller to compact and level the plain soil layer. Since a light roller is used for rolling, the compaction degree of the plain soil layer is small, so that The plain soil layer becomes smooth and at the same time facilitates the mixing of the subsequent road mixer;

[0046] S2: Spread the lime layer, spread the lime on the plain soil layer, and level the lime layer. The thickness of each part of the leveled lime layer is uniform, so that the subsequent road mixer can mix the lime layer and the upper part of the plain soil layer. mix together;

[0047] S3: Mixing, using a road mixer to mix the...

Abstract

The invention relates to a lime soil filling construction method, which relates to the technical field of road construction, and comprises the following steps: paving a plain soil layer, paving plain soil on a lower bearing layer, and compacting and leveling the plain soil layer; paving a lime layer, paving lime on the plain soil layer, and leveling the lime layer; mixing: mixing the upper parts of the lime layer and the plain soil layer together by using a road mixer; in the mixing process, the road mixer measures the upper surface of the compacted plain soil layer and measures the upper surface of the invaded plain soil layer at the same time, the obtained height difference is the invasion depth, and servo control is conducted on the mixing depth of the road mixer according to the invasion depth. In the whole construction process, the depth of the road mixer invading into the plain soil layer is continuously measured and adjusted. The uniformity of the depth of the road mixer invading into the plain soil layer during mixing is improved.

Description

technical field [0001] The present application relates to the field of road construction, in particular to a construction method of lime soil filling. Background technique [0002] Lime soil refers to the combination of lime and plain soil on the lower bearing layer in road construction to strengthen the middle layer of the road surface and roadbed. The difference between lime soil and plain soil filling lies in the control of water content, the uniformity of the mixture, the control of the depth of mixing, and the guarantee of compaction. These factors are the key points of technical operation that directly affect the construction of lime soil. [0003] At present, the public date is October 20, 2020, and the Chinese invention patent application with the publication number CN111794029A proposes a lime soil filling construction method, which includes paving the plain soil layer, rolling the plain soil layer, paving the lime layer and For steps such as mixing, in the mixing ...
