The method promotes most of the excavation slag to directly roll to the slag collecting platform, effectively reduces the slag collection of the excavation area, greatly reduces the workload of manual slag removal, and further shortens the construction period.
Description
Technical field
The present invention relates to hydraulic and hydroelectric engineering Dangerous Rock Body Treatment process fields, and in particular to a kind of high efficiency Dangerous Rock Body is artificial
Excavation method.
Background technique
Currently, Dangerous Rock Body adverse geological condition is very common, almost during the development & construction of hydraulic and hydroelectric engineering
Each project more or less can be related to the improvement of Dangerous Rock Body.Currently, the improvement about Dangerous Rock Body, resolution is more,
But macroscopic destruction is still a kind of very common resolution.For excavation, current Mechanization Level is higher, rock excavation
Mechanized construction technique also comparative maturity, but Dangerous Rock Body a kind of so is also encountered in engineering, they have following feature：
High, steep, processing project amount and work surface less, can not build Transportation Highway to excavate region, mechanical equipment is difficult to be transported to construction
Work surface.Such Dangerous Rock Body is although small, but since work surface is little, traffic difficult arrangement, mechanical equipment is difficult to transport
To operation side, and in operation side it is difficult to keep away quick-fried, and do mechanization operation is caused to be difficult to carry out, in such cases, adopted
Manually operation be have to using method, however, traditional artificial construction method general work efficiency is lower, consumption of manually slagging tap
Time-consuming more, the construction period is longer, encounters geographical location locating for Dangerous Rock Body to the influential situation of major project construction, then endangers
The processing duration of rock mass will directly influence the time of completion of engineering.
Summary of the invention
The present invention is intended to provide a kind of high efficiency Dangerous Rock Body hand excavation's method, with solve that work surface is small and mechanical equipment without
Method working efficiency existing when being transported to the small-sized Dangerous Rock Body of operation side using hand excavation's operation is low, consumption of manually slagging tap
The problems such as duration, long construction period.
The present invention is achieved by following technical solution：
A kind of high efficiency Dangerous Rock Body hand excavation's method, this approach includes the following steps：
(1) compare the upstream side of Dangerous Rock Body and the topographic and geologic situation in downstream side, in the side that topographic and geologic condition is excellent
To excavating at the top of work surface, scaffold is built when can not build sidewalk in local sharp regions for sidewalk；
(2) quick-fried and slag-tapping device will be bored using sidewalk be carried to operation side；
(3) slag charge collection slag platform is set in the lower part shoulder of Dangerous Rock Body；
(4) Dangerous Rock Body is divided into several layers subregion, includes several piecemeals in each subregion, according to sequence from top to bottom
The blast working of subregion is carried out, the slag charge generated after explosion falls into slag charge collection slag platform, and collection slag platform discontinuity is slagged tap；
(5) supporting is carried out after excavating one layer of subregion, using riding track as foot after the completion of the work surface for being equipped with riding track is excavated
The supporting of hand cradle set up basis and excavate region；
(6) collection slag is carried out to the slag charge hoarded in Dangerous Rock Body lower part slope surface pocket；
(7) after the completion of excavating, Dangerous Rock Body lower part slope surface is thoroughly cleared up.
The step (4) is divided into following steps：
Dangerous Rock Body is divided into the piecemeal of several quadrangles according to horizontal direction and upper left inclined direction by (4-1), towards bottom right
All piecemeals in the same plane of side are divided into a subregion；
Piecemeal in (4-2) same layer subregion buries explosion filler, with subregion explosion order from the bottom to top；
(4-3) same layer by stages drops down onto region of slagging tap along natural grade every blast working, slag charge, and same layer subregion explosion is complete
At rear collection slag and slag tap；
(4-4) repeats step (4-2)-(4-3) until all subregions are fully completed construction.
Dangerous Rock Body construction period carries out the concussion of blasting safety monitoring and slope stability safety monitoring of construction period.
The height and the width of every layer of piecemeal in the step (4) are 2-8m.
The width for the sidewalk being arranged in the step (1) is 1-2m.
Interval blasting time in the step (4-3) is 1-5s.
The beneficial effects of the invention are as follows：
Compared with prior art, high efficiency Dangerous Rock Body hand excavation's method provided by the invention, for " high, steep, processing work
Journey amount and work surface less, without traffic, mechanical equipment are difficult to be transported to operation side " Dangerous Rock Body, dexterously according to " from outer
It is interior, from outward appearance to inner essence, successively remove " principle, carry out subregion and sequence explosion divided to plan, with batch blast area, and reasonable arrangement is quick-fried
Broken interval time and explosion order, explosion order consider successively explosion from the bottom to top, are conducive to excavated material after explosion
It is tumbled naturally along natural grade to region of slagging tap, it is flat to collection slag that this method promotes most excavation slag charge directly to tumble
Platform is effectively reduced the collection slag for excavating region, greatly reduces workload of manually skimming, and then shorten the duration.
