Description
Technical field
The present invention relates to Hydraulic and Hydro-Power Engineering Dangerous Rock Body Treatment process field, be specifically related to a kind of high efficiency Dangerous Rock Body artificial
Excavation method.
Background technology
At present, during the development & construction of Hydraulic and Hydro-Power Engineering, Dangerous Rock Body adverse geological condition is the most common, almost
Each project can more or less relate to the improvement of Dangerous Rock Body.Currently, with respect to the improvement of Dangerous Rock Body, resolution is more,
But macroscopic destruction is still very conventional a kind of resolution.For excavation, current Mechanization Level is higher, rock excavation
Mechanized construction technique also comparative maturity, but engineering also encounters such class Dangerous Rock Body, and they have the feature that
High, steep, process quantities and the scope of operation is little, cannot build Transportation Highway to excavating region, plant equipment is difficult to be transported to construction
The scope of operation.Although this type of Dangerous Rock Body is small, but owing to the scope of operation is little, traffic difficult arrangement, plant equipment is difficult to transport
To operation side, and it is difficult to keep away at operation side quick-fried, and causes do mechanization operation to be difficult to carry out, in such cases, adopt
It is the method having to use by manual work, but, Traditional Man construction method general work is inefficient, consumption of manually slagging tap
Time-consuming more, the construction period is longer, run into geographical position residing for Dangerous Rock Body on major project construct influential situation, then endanger
The duration that processes of rock mass will directly influence the time of completion of engineering.
Summary of the invention
It is desirable to provide a kind of high efficiency Dangerous Rock Body hand excavation's method, with solve that the scope of operation is little and plant equipment without
Method is transported to existing inefficiency when the small-sized Dangerous Rock Body of operation side uses hand excavation's operation, manually slags tap consumption
The problems such as duration, construction period length.
The present invention is achieved by following technical solution:
A kind of high efficiency Dangerous Rock Body hand excavation's method, the method comprises the following steps:
(1) upstream side of Dangerous Rock Body and the topographic and geologic situation in downstream are compared, in the side that topographic and geologic condition is excellent
Sidewalk is to excavation scope of operation top, and locally scaffold is built when cannot build sidewalk in sharp regions；
(2) utilize sidewalk that quick-fried for brill and slag-tapping device are carried to operation side；
(3) shoulder, bottom at Dangerous Rock Body arranges slag charge collection slag platform；
(4) if Dangerous Rock Body to be divided into dried layer subregion, some piecemeals are included in each subregion, according to order from top to bottom
Carrying out the blast working of subregion, the slag charge produced after explosion falls into slag charge collection slag platform, and collection slag platform discontinuity is slagged tap；
(5) carry out supporting after one layer of subregion of excavation, utilize packway as foot after the scope of operation being provided with packway has been excavated
The basis of setting up of hand cradle carries out excavating the supporting in region；
(6) carry out collecting slag at the slag charge of the domatic pocket in Dangerous Rock Body bottom to hoarding；
(7), after having excavated, clear up thoroughly Dangerous Rock Body bottom is domatic.
Described step (4) is divided into following steps:
(4-1) according to horizontal direction and upper left incline direction, Dangerous Rock Body is divided into the piecemeal of some tetragons, towards bottom right
All piecemeals in the same plane of side are divided into a subregion；
(4-2) bury explosion filler underground with the piecemeal in layer subregion, with subregion explosion order from the bottom to top；
(4-3) drop down onto, along natural grade, region of slagging tap every blast working, slag charge with layer by stages, complete with layer subregion explosion
Collect slag after one-tenth and slag tap；
(4-4) step (4-2)-(4-3) is repeated until all subregions are fully completed construction.
Dangerous Rock Body construction period carries out concussion of blasting safety monitoring and the slope stability safety monitoring of construction period.
The height and the width of every layer of piecemeal in described step (4) are 2-8m.
The width of the sidewalk arranged in described step (1) is 1-2m.
Interval blasting time in described step (4-3) is 1-5s.
The invention has the beneficial effects as follows:
Compared with prior art, high efficiency Dangerous Rock Body hand excavation's method that the present invention provides, for " high, steep, place's science and engineering
Journey amount and the scope of operation are little, be difficult to be transported to operation side without traffic, plant equipment " Dangerous Rock Body, dexterously according to " from outward
In, from outward appearance to inner essence, successively peel off " principle, carry out subregion point sequence explosion planning, with batch blast area, reasonable arrangement is quick-fried again
Broken interval time and explosion order, explosion order considers that explosion the most successively, beneficially excavated material are the most permissible after explosion
Naturally tumbling to region of slagging tap along natural grade, it is flat that this method promotes most excavation slag charge directly to tumble to collection slag
Platform, is effectively reduced the collection slag in excavation region, greatly reduces workload of manually skimming, and then shorten the duration.
