Embodiment 1

[0043] In order to achieve the above object, the present embodiment proposes a method, comprising the following steps:

[0044] (1) Level the site for the excavation section of the cutting, carry out measurement and setting out, measure and release the middle pile of the route, and excavate the upper edge pile of the cutting;

[0045] (2) Manually cooperate with excavators, bulldozers and loaders to clear the surface of the subgrade within the project scope, and transport the cleared topsoil to the designated place for centralized stacking, and use it as the later site recultivation or backfill planting soil;

[0046] (3) According to the re-measured original ground elevation, stake out according to the pile number spacing of the cross section on the design drawing, determine the excavation positions of the middle pile, side pile, broken down platform and cutting top, keep track and measure, and ensure that the slope One-time molding and meet design and specification requireme...

Abstract

The invention provides a cutting earthwork construction method. According to the cutting earthwork construction method, the blasting design is reasonable, a slope rockfall prevention device can be arranged on the outer layer in the blasting stage and the excavation stage, after a cutting is constructed, the slope rockfall prevention device is arranged for rockfall prevention and control, and the technical problem that in the prior art, in the cutting earthwork construction process, rockfall protection is poor can be solved.

Description

technical field [0001] The invention relates to the technical field of road cutting blasting excavation, in particular to an earthwork construction method for road cuttings. Background technique [0002] Excavation of existing road cuttings is likely to cause rockfall, which will cause danger to the traffic lane below. The existing excavation construction method and protection structure are not good for protection against falling rocks. The main problems of its poor rockfall protection are concentrated in the cutting earthwork blasting stage and excavation stage. Among them, cutting earthwork blasting refers to the use of explosives, detonators and other blasting materials to blast earthwork during road construction to achieve the purpose of excavation. And how to do a good job in implementing the protection work in the cutting earthwork construction process is a problem that those skilled in the art need to solve urgently. Contents of the invention [0003] In view of ...
