Problems solved by technology

To build roadbeds in desert areas, if ordinary cohesive soil is to be used, it needs to be transported from a long distance. Not only is it difficult to obtain soil, but it will also greatly increase the project cost and prolong the construction period.

Embodiment 1

[0040] The specific construction method is as follows: a roadbed construction method is provided, including the following steps:

[0041] (1) Measurement and setting out: mark the area to be constructed, and the two sides of the roadbed need to exceed the design standard width of the roadbed by 0.5 meters.

[0042] (2) Lay the bottom layer: Remove the debris on the original road surface and level the surface; pave a 20cm gravel soil layer or gravel soil layer on the leveled surface, and roll it as the construction surface after leveling.

[0043] (3) Packing: Calculate the paving area of ​​each vehicle according to the transportation volume of the dump truck and the loose paving thickness of the fine sand, use a ruler to draw the line, draw the network white grid of the paving area, and use the dump truck to press the fine sand according to the grid Reverse unloading, so that the dump truck always walks on the gravel soil layer or gravel soil layer; every time a truck of fine ...

Embodiment 2

[0055] The specific construction method is as follows: a roadbed construction method is provided, including the following steps:

[0056] (1) Measurement and setting out: mark the area to be constructed, and the two sides of the roadbed need to exceed the design standard width of the roadbed by 0.6 meters.

[0057] (2) Lay the bottom layer: Remove the debris on the original road surface and level the surface; pave a 30cm gravel soil layer or gravel soil layer on the leveled surface, and roll it as the construction surface after leveling.

[0058] (3) Packing: Calculate the paving area of ​​each vehicle according to the transportation volume of the dump truck and the loose paving thickness of the fine sand, use a ruler to draw the line, draw the network white grid of the paving area, and use the dump truck to press the fine sand according to the grid Reverse unloading, so that the dump truck always walks on the gravel soil layer or gravel soil layer; every time a truck of fine ...

Embodiment 3

[0070] The specific construction method is as follows: a roadbed construction method is provided, including the following steps:

[0071] (1) Measurement and setting out: mark the area to be constructed, and the two sides of the roadbed need to exceed the design standard width of the roadbed by 0.8 meters.

[0072] (2) Lay the bottom layer: Remove the debris on the original road surface and level the surface; pave a 30cm gravel soil layer or gravel soil layer on the leveled surface, and roll it as the construction surface after leveling.

[0073] (3) Packing: Calculate the paving area of ​​each vehicle according to the transportation volume of the dump truck and the loose paving thickness of the fine sand, use a ruler to draw the line, draw the network white grid of the paving area, and use the dump truck to press the fine sand according to the grid Reverse unloading, so that the dump truck always walks on the gravel soil layer or gravel soil layer; every time a truck of fine ...

Abstract

The invention discloses a method for constructing a roadbed through sand filling, and belongs to the field of traffic construction. In the technical scheme, the method is characterized by including the steps of surveying and setting out, surface clearing, filling, reinforcing, mixing, rolling compaction of a bulldozer, rolling compaction of a road roller and paving. The method solves the technicalproblem that in the prior art, the roadbed is prone to losing stability and deforming, and is applied to road construction to enhance the effect of roadbed stability.

Description

technical field [0001] The invention relates to a roadbed construction method, more specifically to a roadbed construction method. Background technique [0002] Aeolian sand is produced by sand being moved to the alluvial plain area by wind-blown sand flow to form sand dunes. It has the characteristics of loose structure, poor gradation, large porosity, low strength, good water stability, uniform settlement, and less affected by unfavorable seasons. To build roadbeds in desert areas, if ordinary cohesive soil is to be used, it needs to be transported from a distance, which is not only difficult to obtain soil, but also greatly increases the project cost and prolongs the construction period. In line with the principle of obtaining local materials and reducing project cost, it is of course best to use aeolian sand that can be obtained locally as the main filler for filling the roadbed. Because aeolian sand is in a loose state under natural conditions, its cohesion is basical...
