Embodiment 1

[0024] Example 1: A method for borrowing soil during road construction, including the following steps: S1: Route survey, surveying surrounding land along the road; S2: Selecting a borrow site, and selecting the vertical distance from the road according to the survey situation The nearest and barren place is used as a borrow site, and there are several barren slopes in the borrow site; S3: excavate earth, dig hole 1 beside the barren slope, and transport the excavated soil to the road construction site; S4: in Pick No. 1 waste slope next to No. 1 pit, scrape off the surface of No. 1 waste slope and pile it aside, fill half of the remaining soil on No. 1 waste slope into No. 1 pit, and transport the other half to the road construction site; S5: Fill the river silt in the No. 1 pit; S6: Backfill the soil in step S4 to the upper layer of the No. 1 pit; S7: Dig down the No. 2 pit on the ground where the original No. 1 barren slope is located, and the excavated The soil is transporte...

Embodiment 2

[0031] The second embodiment: the difference from the first embodiment is that in step S4, the sand backfilled into the No. 1 pit from the waste slope No. 1 is piled up in a truncated cone shape, and the top surface of the truncated cone is lower than the upper edge of the No. 1 pit. The silt is filled along the side wall of the round table, and the soil is laid on the upper layer. When backfilling the soil from the No. 1 barren slope into the No. 1 pit, because the soil in the middle of the No. 1 barren slope is mostly a mixture of sand and gravel, the particles are larger and harder, so they are rounded in the No. 1 pit. Shaped stacking can improve the stability of the foundation in Pit 1 to a certain extent.

Abstract

The invention discloses a soil taking method in a road construction process, and aims to solve the problem that taken soil is destructed severely in a conventional road repair process. According to the technical scheme adopted by the invention, the key point is that the soil taking method in the road construction process comprises the following steps of: performing line investigation, selecting aravel-soil-taken field, excavating earthwork, scraping off soil skin of a 1# slope surface layer and stacking the soil skin at one side, filling one half of the rest of the soil of the 1# slope into a1# pit, transporting the other half of the soil to a road repair position, filling river-way silt into the 1# pit, and filling soil skin back into the upper layer of the 1# pit. According to the soiltaking method in the road construction process disclosed by the invention, the slope in a barren area is sufficiently utilized, soil-taken ground is not damaged and the soil texture is improved.

Description

Technical field [0001] The invention relates to the technical field of municipal engineering, and more specifically, it relates to a method for borrowing soil during highway construction. Background technique [0002] Municipal engineering generally belongs to the country’s infrastructure, is an indispensable material foundation for the survival and development of cities, and is a basic condition for improving people’s living standards. Road traffic is particularly important. At present, roads in my country are generally linear land, and the road front is relatively Long often cross the administrative boundary, so the construction of the highway in the process of construction uses a large amount of soil. However, the large amount of soil used for construction and the long distance of borrowing will cause waste of land in the process of land acquisition and use of soil, which will damage the environment, high production costs, extended construction period and many ownership units i...
