A slope blasting method

Abstract

This application relates to a slope blasting method, comprising the following steps: S1. Construction preparation; S2. Drilling operation; S3. Charge network; S4. Plugging holes; ; S8, cleaning up the crushing table. The application not only improves the firmness of the connection between the crushing table and the mountain body, but also facilitates the staff to make the crushing table.

Description

technical field [0001] The present application relates to the field of highway roadbed side slope construction technology, in particular to a side slope blasting method. Background technique [0002] Slope refers to a slope with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. Classification by cause: It can be divided into artificial slope and natural slope. At present, when roads are constructed in mountainous areas, they are generally built as roads around the mountains, and in order to ensure that the mountains at the edge of the roads are not prone to landslides, slopes are generally built on the mountains to reduce landslides. [0003] During the construction of the slope, blasting is generally used to pretreat the slope to achieve the effect of rapid prototyping of the slope as a whole. [0004] In mountain highway engineering, the excavation of stone cuttings mainly adopts blasting construction technology. Among them, pre-sp...

Problems solved by technology

[0004] In mountainous highway engineering, the excavation of rocky cuttings mainly adopts blasting construction technology. Among them, pre-splitting or smooth blasting is mainly used to control the line shape of subgrade slope. method, the ground at the bottom of the blast hole is uneven and honeycombed, and the rock mass at the ultra-deep part of the blast hole is seriously broken, especially in the blasting construction where the crushing platform is set on the side slope. In the range of ultra-deep blastholes, the rock mass of the falling platform is severely broken or even difficult to form, which reduces the stability of the slope, loses the safety protection function of the falling platform, and increases the construction cost

And on the other hand, in order to make the slope appear in a graded form after forming, it is generally necessary to set up a crushing table before blasting, which will also increase the construction cost to a certain extent.
