Earth rock excavation construction method

Abstract

The invention provides an earth rock excavation construction method. The method comprises the steps that survey and setting out is performed, specifically, an earth rock excavated section is measuredpractically before construction, and paying off is performed before earth rock excavation; ditch building is performed, specifically, ditch building is performed before earth rock excavation, and a temporary drainage system is built; exploding and excavation are performed, specifically, earth rock excavation is performed from top to bottom layer by layer and section by section, a slope is controlled according to the designed slope ratio, during earth rock excavation, construction is performed by adopting a hydraulic cannon machine and an excavator, a deep hole smooth surface blasting technology is adopted for exploding, and in terms of a roadbed top surface of a stone through cut, construction is performed by adopting small dense volley guns; and soil and stone transportation is performed,specifically, whether excavated soil and stone meet fill material requirements or not is detected, and if yes, the soil and stone are transported to a fill road section. The earth rock excavation construction method is suitable for complex terrain environments and has the advantage that influences on the surrounding environment are small.

Description

technical field [0001] The invention relates to the technical field of earth-rock excavation, in particular to an earth-rock excavation construction method. Background technique [0002] Earthwork excavation is a key process in the initial stage of the project and even in the construction process. It is mainly a project that loosens, breaks, excavates and transports soil and rocks. According to the nature of rock and soil, earthwork excavation can be divided into earthwork excavation. and stone excavation. Among them, in stonework excavation, in addition to loose rocks that can be excavated by chisel rippers, general stonework excavations need to loosen and break rocks by blasting, and excavate with manual and semi-mechanized equipment, such as , You can use simple tools such as spade picks, pneumatic picks, and pneumatic drills to cooperate with lifting or this simple and small transportation tool for operations. However, the environmental factors of earthwork excavation ...

AI Technical Summary

Problems solved by technology

However, the environmental factors of earthwork excavation vary from place to place, resulting in some complex terrain environments accompanied by lines such as natural gas pipelines and electric towers, making it impossible to use conventional blasting techniques for stonework excavation, and large-scale blasting is strictly prohibited
