Abstract

The invention discloses a cutting-type excavation stone cutting construction method and stone cutting, including the following steps: S101, measuring and setting out, obtaining the number of target cutting layers of the rock in the subgrade area of ​​the target stone section and the corresponding each The cutting parameters of the layer target cutting layer, S102, according to the obtained number of layers of the target cutting layer and the corresponding cutting parameters of each layer of the target cutting layer, each layer of the target cutting layer is sequentially cut from top to bottom, and the entire layer Construction is carried out until the surface of the rock in the subgrade area of ​​the target masonry section is sunken to form the target masonry cutting, and the side slopes on both sides of the subgrade of the target masonry cutting are in the shape of an outwardly expanded ladder. The cutting-type excavation stone cutting construction method of the present invention solves the problem of poor stability of the slope due to vibration damage in the existing stone cutting and side slope during the blasting excavation process and large safety hazards in blasting excavation construction. technical problem.

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 ...
