Abstract

The invention discloses a construction method for excavating of a stone cutting in a cutting mode and the stone cutting. The method comprises the following steps that S101, measuring and setting out are conducted, specifically, the number of target cutting layers of rock in a roadbed region of a target stone section and the cutting parameters of each corresponding target cutting layer are obtained; and S102, according to the obtained number of the target cutting layers and the corresponding cutting parameters of each target cutting layer, the target cutting layers are cut in sequence from topto bottom, and full-layer construction is conducted till the surface of the rock in the roadbed region of the target stone section sinks inwards to form a target stone cutting, and the slopes on the two sides of the roadbed of the target stone cutting are in an outwards-expanded step shape. According to the construction method for excavating of the stone cutting in a cutting mode, the technical problems that in the blasting excavation process of an existing stone cutting and side slopes, due to vibration damage, the stability of the side slopes is poor, and potential safety hazards of blastingexcavation construction are large are solved.

Description

technical field [0001] The invention relates to the technical field of excavation and construction of stonework cuttings in highways, in particular to a construction method for excavating stonework cuttings by cutting. The invention also relates to a stone road cutting. Background technique [0002] Excavation of existing highway stone cuttings and side slopes is excavated by blasting method. The specific methods are as follows: 1. Preliminary preparation: including blasting safety assessment, handling legal blasting procedures; measuring and setting out, reviewing the piles in the subgrade, and determining the excavation sideline according to the actual ground elevation; layout control and drilling, according to the designed hole location map Carry out deployment and control, control the direction, angle and depth of the drilling hole according to the deployment control position to drill; charge explosives, check the condition of the blast hole, remove water and debris in ...
