Problems solved by technology

The mixing depth is generally carried out manually. After the road mixer has mixed the mixture, use an iron mill to check the mixing depth. There are also mixers with automatic depth control for mixing depth control, but the price is relatively high. expensive
The automatic control device for mixing depth is an electronic structure, and the sensor will often fail due to the size of the soil clods during mixing, and the maintenance cost is expensive. At the same time, it is difficult for the automatic control device to compensate for the inconsistency of the depth between the old and new tools.

Embodiment 1

[0037] like figure 1 As shown, a lime-soil filling construction method is characterized in that, comprises the following steps:

[0038] A1. Pave colored lime with a thickness of 1cm at the starting point of the route construction on the lower bearing layer, and the length is 10-15m;

[0039] A2. Pave the plain soil layer, turn the soil to the required water content, and the soil blocks are all less than 15mm, and the plough can be used for the construction;

[0040] A3. Light-duty road roller for rolling;

[0041] A4. The cross slope is re-measured and leveled, and wavy surfaces are not allowed;

[0042] A5. Draw lime grids and spread lime, and use scraper 1 to level the upper surface of lime. After the surface is flat, the lime blocks should not exceed 5mm;

[0043] A6. The road mixer is in place, and firstly, the trial mixing is carried out at 10-15m from the starting route;

[0044] A7. According to the drawing, set the thickness of the lime soil layer plus the thickne...

Embodiment 2

[0053] like figure 2 and image 3 As shown, a further improved solution on the basis of Embodiment 1, the front side of the scraper 1 is integrally connected with a breaking part 11, and the bottom of the breaking part 11 and the bottom of the scraper 1 are integrally connected with the same horizontal part 12, Both sides of the breaking part 11 are inwardly concave arc structures. The horizontal part 12 can be used to smooth the path of the demolition part 11 first, and the demolition part 11 will be raised higher than the design height to remove the arc structure and move to both sides and evenly spread, effectively improving the efficiency and construction quality of tiling.

[0054] In a further improved solution in this embodiment, the scraper 1 is rotatably connected with two sets of connecting rods 13 at the front and rear, and both sets of connecting rods 13 are connected with rolling rollers 14 , and one set of rolling rollers 14 is located behind the scraper 1 . T...

Abstract

The invention discloses a lime soil filling construction method, which belongs to the field of filling construction. The present invention adopts secondary mixing and paving lime in grids, so that the construction depth of lime soil on site is effectively guaranteed, and the existence of plain soil interlayer is avoided. This method also avoids the depth error caused by the expensive road mixer with automatic depth adjustment, and solves the difficulty that the mixing efficiency cannot be guaranteed due to the size and water content of the concrete material that cannot be guaranteed by humans or machinery. . The use of grid scrapers to pave lime also makes lime paving smoother, liberates the hands of operators, and improves the production efficiency of operations.

Description

technical field [0001] The invention relates to a filling construction method, which is especially suitable for the technical scope of di-lime soil construction in road construction. Background technique [0002] Lime soil refers to the combination of lime and plain soil on the lower bearing layer in road construction, so as to strengthen the middle layer of the good process of the road surface and the roadbed. The difference between lime soil and plain soil filling lies in the control of water content, the uniformity of the mixture, the depth control of mixing, and the assurance of compaction. These factors are the technical operation points that directly affect the lime soil construction. [0003] During regular construction: [0004] 1. The construction process of lime soil is: quality acceptance of the lower bearing layer - plain soil paving - sunning according to the moisture content of plain soil - virtual pressure leveling - cross-cutting - upper digested quicklime -...
