Abstract
The invention discloses the blasting construction methods that rock slope related in civil engineering excavates a kind of control rock slope regularity and stability in field.Its work progress are as follows: firstly, the geologic information of exploration construction area, carries out drainage works before construction；Then, first the topsoil excavation of side slope is cleared in work progress, then the rock on pre -arranged layer top is carried out by Blasting Excavation using the method for explosion；Finally, carrying out pre -arranged layer explosion, a pipe pack is filled in blasthole bottom and carries out secondary blasting.It can control the regularity and stability of rock slope using such construction method, reduce to construct as onepull and be destroyed caused by Slope Stability, so that it is guaranteed that the safety of side slope.Unnecessary earthwork evacuation can be reduced to reduce operating expenses simultaneously, and guarantee is provided to the safe handling of road.
Description
Technical field
The present invention relates to a kind of blasting construction methods for controlling rock slope regularity and stability, especially for deep-cutting road
The construction method that moat rock slope is excavated.
Background technique
Rock slope is common side slope type in road construction.Currently, greatly developing with China's road engineering,
The road construction of especially mountainous region in middle and western China is quickly grown, and rock slope is one of most important side slope type of mountain road.Cause
This, the Rational Excavation of rock slope has vital effect for road safety, and the digging mode of rock slope determines stone
The safe handling of matter side slope.
Common rock slope construction technology is to be excavated using onepull side slope, then carries out construction protection.
Defect that there are three the excavation methods: (1) the side slope surface irregularity after excavating；(2) side slope and side slope lower part can be destroyed
The stability of rock, the safety of side slope bring certain hidden danger；(3) work progress is complex, it is difficult to a wide range of to promote
It uses.
Summary of the invention
In order to overcome the defects of above-mentioned rock slope construction technology, the present invention provides a kind of control rock slope ride comfort
With the blasting technique of stability, it is characterized in that pre -arranged layer, carries out secondary blasting later.Construction the following steps are included:
A, geologic information, including native stone boundary, rock stratum weathering thickness and degree of crushing, the construction feature etc. of rock stratum are reconnoitred in detail；
B, intercepting ditch is carried out in top of the slope, intercepts the surface water；
C, the soil layer on side slope surface is excavated and is cleared.
D, detailed design is carried out, explosion bulge test is then carried out, further corrects blasting parameter by testing；
E, Loose Control Blasting is carried out to periphery rock mass position, reaches the requirement of pre -arranged layer position；
F, firstly, the blasting parameter according to determined by explosion bulge test, determines reserved light explosion layer blasting boreholes position and calculate fried
Survival dose, and then configure pack；Then, a pipe pack is filled in blasthole bottom, top connects primacord；It is checked finally, doing check.
G, explosion is attached to primacord.
Beneficial effects of the present invention are mainly: it is quick-fried that light is reserved on the basis of deep hole blasting, photoface exploision and short hole blasting
Layer carries out excavation construction to rock slope using secondary blasting technology.It is easy for construction, it can effectively control safety caused by explosion
Harm；It most has the advantages that the in-place blasting out reduced to cut slope and cutting bedding lower part rock, reduces due to construction pair
In the destruction of rock slope stability, to guarantee the stability of rock slope；The ride comfort of excavation slope is improved, is reduced super deficient
It digs.Therefore, the program can reduce construction volume while guaranteeing rock slope stability.
Detailed description of the invention
Fig. 1 is the distribution of rock slope rock mass and pre -arranged layer position charge constitution schematic diagram；
1. top of the slope intercepting ditch in Fig. 1,2. side slope surface soil layers, 3. peripheral part lithosomes, 4. pre -arranged layer rock mass, 5. explosions
Drilling, 6. packs.
Specific embodiment
With reference to the accompanying drawing 1 and embodiment the present invention is further described.
[embodiment]
Referring to attached drawing 1, in order to overcome in the prior art during rock slope Excavation blasting caused by side slope ride comfort and steady
Qualitative undesirable deficiency, the present invention provides a kind of blasting technique for controlling rock slope regularity and stability, it is characterized in that in advance
The quick-fried layer of light is stayed, secondary blasting is carried out.Construction the following steps are included:
A, geologic information, including native stone boundary, rock stratum weathering thickness and degree of crushing, the construction feature etc. of rock stratum are reconnoitred in detail.
B, top of the slope intercepting ditch 1 is carried out in top of the slope, intercepts the surface water.
C, side slope surface soil layer 2 is excavated and is cleared.
D, it carries out detailed design and carries out explosion bulge test, further correct blasting parameter by testing.
E, Loose Control Blasting is carried out to peripheral part lithosome 3, until meeting wanting for 4 position of pre -arranged layer rock mass
It asks.
F, firstly, the blasting parameter according to determined by explosion bulge test, determines reserved 4 blasting boreholes of light explosion layer, 5 position, meter
Explosive consumption is calculated, and then configures pack 6；Then, a pipe pack 6 is filled in blasthole bottom, top connects primacord；Finally, doing school
Nuclear inspection.
G, explosion is attached to primacord.
Claims (2)
1. controlling the blasting construction method of rock slope regularity and stability, which is characterized in that firstly, carrying out detailed geology
It reconnoitres, carries out top of the slope intercepting ditch (1), and excavate cleaning side slope surface soil layer (2)；Then, at using Loose Control Blasting means
It manages peripheral part lithosome (3), the requirement until meeting pre -arranged layer rock mass (4) position；Finally, using secondary blasting technology
