Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem that the above-mentioned existing roadbed treatment process is simple and does not adopt a standardized treatment method, which causes problems in the roadbed after a period of use, resulting in subsidence of the road, and even the interruption of the road. The construction method of quickly filling the roadbed in road construction, through reasonable and standardized processing methods, can make the roadbed structure stable, and there will be no quality problems in subsequent use, ensuring the service life of the road and enhancing the ability to resist natural disasters , to solve the problem that the existing roadbed treatment process is simple, and no standardized treatment method is adopted, which makes the roadbed have problems after a period of use, causing road settlement and even road interruption

Embodiment

[0015] Carry out the construction method of fast filling embankment in road construction, comprise the following steps:

[0016] (1) Stakeout: According to the coordinates of the middle pile of the main line given by the design, use the total station to release the middle pile position, set a middle pile at 20 meters for the section with large ups and downs, set a middle pile at 40 meters for the relatively flat section, and then use a level Measure the original ground level elevation pile by pile, measure the cross section with the total station, draw the ground line and subgrade section on the MiG paper, calculate the position of the left and right side piles, and release the side piles on the spot;

[0017] (2) Cleaning up the list: Use manual or mechanical methods to clean up weeds, tree roots, organic impurities and garbage within the construction area. All the cleaned up waste should be transported to the designated place. The bulldozer loosens 15-25cm, and then uses a g...

Abstract

The invention discloses a construction method for quickly filling a subgrade in road construction, which comprises the following steps: lofting, surface cleaning, rolling before filling, layered filling, subgrade forming, and side slope shaping. This method can make the subgrade structure stable through a reasonable and standardized treatment method, and there will be no quality problems in subsequent use, which ensures the service life of the road, enhances the ability to resist natural disasters, and solves the existing problem of simple treatment of the subgrade. , did not adopt a standardized treatment method, resulting in problems with the roadbed after a period of use, resulting in settlement of the road, and even road interruption.

Description

technical field [0001] The invention relates to a method, in particular to a construction method for quickly filling roadbeds in road construction. Background technique [0002] The literal meaning of highway is public road, public transportation road, many vehicles such as automobiles, bicycles, rickshaws, horse-drawn carriages and pedestrians can walk, of course, different roads have different restrictions. It is also called Malu among the people, such as the usage in "Malu Angel", which is not limited to the exclusive use of horses. There are general roads and car-only roads, and there are more and more of the latter, so there are two types of secondary roads. [0003] Generally, roads are divided into several technical grades according to the annual average day and night traffic volume and their usage tasks and properties. The "Technical Standards for Highway Engineering" published by China People's Communications Press in 2004 divides roads into five technical grades....
