Problems solved by technology

[0003] a. Excavating the slope mechanically cannot carry out high slope trimming, long construction period, low efficiency, low economic benefit, and poor quality of slope formation;
[0004] b. Excavation by traditional blasting method will cause great damage to the retained rock mass, resulting in over-excavation and under-excavation, which will damage the stability of the slope;
[0005] c. Manual slope treatment has great flexibility, consumes a lot of manpower, has a long construction period, low efficiency, and low economic benefits

Abstract

The invention discloses a side slope excavation smooth-surface blasting-method construction method. The side slope excavation smooth-surface blasting-method construction method comprises the steps of 1 researching a design drawing and geological information and cleaning a slope crest and the way leading to a mountain, 2 performing surveying and setting out, 3 designing smooth-surface blasting parameters, 4 performing setting out and hole arrangement, 5 establishing a drill machine platform and positioning the drill machine platform, 6 drilling holes, cleaning the holes and checking the holes, 7 performing cartridge processing and charging and blocking the top ends of the holes, 8 connecting a detonation network, 9 performing blasting and 10 performing checking after blasting. The side slope excavation smooth-surface blasting-method construction method is short in construction period, low in cost, high in efficiency, small in working amount, good in forming effect, high in safety and simple in construction.

Description

technical field [0001] The invention relates to a blasting method, in particular to a smooth surface blasting construction method for slope excavation. Background technique [0002] The existing slope blasting method has the following defects: [0003] a. Excavating the slope mechanically cannot carry out high slope trimming, long construction period, low efficiency, low economic benefit, and poor quality of slope formation; [0004] b. Excavation by traditional blasting method will cause great damage to the retained rock mass, resulting in over-excavation and under-excavation, which will damage the stability of the slope; [0005] c. Manual slope treatment has great flexibility, consumes a lot of manpower, has a long construction period, low efficiency, and low economic benefits. Contents of the invention [0006] In order to overcome the above-mentioned disadvantages, the present invention provides a smooth surface blasting construction method for slope excavation with...
