specific Embodiment approach 1

[0015] Specific embodiment 1: The method for borrowing soil in the process of highway construction in this embodiment is specifically prepared according to the following steps:

[0016] Step 1. Site selection of borrow pit;

[0017] Step 2: Strip the topsoil of the borrow site and the designed highway;

[0018] Step 3. Backfill the borrow pit after the topsoil stripped and the designed road after stripped topsoil;

[0019] Step 4. Live planting on the borrow yard after backfilling; that is, a method of borrowing in the road construction process is completed. figure 1 Shown.

[0020] Effects of this implementation:

[0021] This embodiment proposes a soil extraction method in the process of road construction. By using this method, soil extraction can not only protect the environment, improve the soil, but even generate new arable land and increase the yield of crops on rural land. On the premise of respecting regulations and laws and ensuring the maintenance of social stability, this im...

specific Embodiment approach 2

[0025] Specific embodiment two: this embodiment is different from specific embodiment one in that the process of selecting the site of the borrow pit in step one is:

[0026] (1) Choosing the borrow yard Choose the borrow yard according to the principle of the proximity of the borrow yard and the designed road; the borrow yard shall be based on the shape of the borrow pit, the area of ​​the borrow pit, the volume of the borrow pit, and the best depth of the borrow pit. , The slope of the borrow pit, the green area required to establish the borrow pit after borrowing, the drainage facilities of the borrow pit, the high hills of the borrow pit, the contour line of the sand dune of the borrow pit, and the volume of the borrow pit-the volume of the borrow pit Select the effect drawing drawn by volume and the road design plan;

[0027] (2) The selected borrow yard adopts the cost approximation method to calculate the cost of each borrow yard, and adopts the income reduction method and t...

specific Embodiment approach 3

[0029] Specific embodiment three: this embodiment is different from specific embodiment one or two in that the process of stripping the topsoil from the borrow pit and the designed highway in step two is:

[0030] (1) Strip the topsoil of the land in the borrow pit area, and the depth of the borrow should be smoothly transitioned to the surrounding cultivated land; the thickness of the stripped soil layer is not less than 30cm, and the thick topsoil layer needs to be cleared to the bottom of the cultivated soil; bulldozers Bulldoze the pile, and then use the loader and dump truck to pile the surface soil of the borrow yard on the yard around the design road borrow pit to avoid mixing of the surface soil and the deep soil;

[0031] (2) To strip the topsoil of the designed highway, first select a soil storage yard on the designed highway, use a bulldozer to bulldoze the pile, and then use a loader and a dump truck to stack the designed highway topsoil on the yard around the borrow pit...

Abstract

The invention relates to an earth borrowing method in the process of highway construction. The earth borrowing method in the process of highway construction is used for solving the problems that due to the fact that the amount of earth needed by construction is large, in the process of land acquisition and earth utilization, earth utilization is difficult, land wastage is caused, the environment is damaged, and tall hillocks, slope wasteland and dunes are low-yield land. The earth borrowing method in the process of highway construction comprises the steps that (1) the site of a borrow area is selected; (2) topsoil stripping is carried out on the borrow area and a designed highway; (3) backfill is carried out on the borrow area after topsoil is stripped, and the designed highway after topsoil is stripped; (4) direct seeding planting is carried out on the borrow area after backfill is carried out. The earth borrowing method in the process of highway construction is applied to the field of earth borrowing methods in the process of highway construction.

Description

Technical field [0001] The invention relates to a method for borrowing soil during highway construction. Background technique [0002] At present, highways in my country are generally linear land, and the highway front line is long and often crosses the administrative boundary. Therefore, the amount of soil used in the construction of the highway is large. 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 soil use and damage the environment. The production cost is high, the construction period is prolonged, and there are many ownership units involved, and it will often cause issues that affect social stability. At present, there are still many high hills, barren slopes, and sandbags in rural areas. Because of their high terrain, no one has reclaimed them. Some high hills, barren slopes, and sandbags have been reclaimed to plant crops, but due to their high terrain The outstan...
