Description
Technical field
The present invention relates to the technical fields of blast working, more specifically, it is related to plaster within the scope of a kind of railway protective
Rock stratum high pressure pneumatic component method.
Background technique
When carrying out blast working within the scope of railway protective, in order to guarantee not cause to damage and do not influence on railway
The normal use of railway, all can strict control explosion influence that stratum is generated, needs are to adopting when carrying out blast working
The equivalent of explosive carries out stringent control.
When carrying out blast working in marl stratum within the scope of railway protective, marl is one kind between carbonic acid
The rock of excessive type between rock salt and clay rock, is made of clay particle and carbonate particle, is in particle or pureed structure；
Usually marl all refer to mixed by flour sand and mud grade carbonate with clay mineral form a kind of it is loose, soft, frangible compared with
New sedimentary rock；Because of the characteristic of marl itself, in process that blast working is carried out in the marl stratum, hold very much
The case where vibration generated when easily because of explosive blasting causes stratum large area to be collapsed；This can cause greatly the safety of construction
It influences, and because is to be very easy to impact the normal use of railway and may be to iron within the scope of railway protective
Road damages, and needs a kind of to complete explosion again and will not generate the blasting method of significant shock now.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to providing within the scope of a kind of railway protective marl
Layer high pressure pneumatic component method, under conditions of quickly heating suddenly, sharply rapid expanding, generates larger liquid carbon dioxide
The mode of impact force carries out explosion, and the vibration of generation is faint when carrying out explosion, it is not easy to generate to the stratum of surrounding broken
It is bad, it can greatly guarantee construction safety and be not easy to impact the normal use of railway.
To achieve the above object, the present invention provides the following technical scheme that marl stratum within the scope of a kind of railway protective
High pressure pneumatic component method, comprising the following steps:
A. assemble: by conducting wire from liquid storage pipe carve characters one end protrude into then from the liquid storage pipe other end stretch out；Level pressure is sheared into piece later
It loads onto gasket and links together with the conducting wire of heating device, level pressure shears one end of piece protrusion inwardly, then pulls out and adds
Thermal, so that level pressure shears piece completely into liquid storage pipe；Release pipe is first manually tightened later, then tightens filling valve again；
Then release pipe and filling valve are tightened using changer respectively, resistance is measured later, normal resistance value is the Europe 1-2
Nurse；
B. it inflates: fracturing device being inflated, carbon dioxide is filled into fracturing device, test the leakproofness of fracturing device later,
The filling valve of fracturing device and release pipe are respectively put into water when test, it is ensured that without a large amount of bubbles；
C. drill: drilling is constructed using down-the-hole drill, drilling it is deep-controlled in 1-3m, drilling arrangement uses "-" type
Formula；
D. explosion: more fracturing devices are sequentially inserted into blast hole, are carried out after then connecting the conducting wire of more fracturing devices
Explosion；
E. it recycles: the fracturing device of the recycling after explosion is transported to operation room, be filled with valve and release pipe is backed out, will cause later
The residue inside device is split to clean out；When carrying out filling valve and release pipe disassembly, dismantled using changer.
By using above-mentioned technical proposal, by being heated to liquid carbon dioxide, so that increased pressure causes 20MPa-
60MPa, the carbon dioxide of high pressure can rapidly be converted into gaseous state, and more than 600 times of volume expansion, the gas expansion energy of abrupt release
Make the rock mass fracturing on drill point periphery, a large amount of heat can be absorbed in the process of liquid carbon dioxide volume expansion, it is calm to reduce
The heat of surrounding rock body, and it is pneumatic when using low-pressure pneumatic, carbon dioxide explosion more many safely than conventional blast
It is the process of volume expansion, so the vibration generated in the moment for carrying out explosion is minimum, it is not easy to be generated to the stratum of surrounding broken
It is bad, it can greatly guarantee construction safety and be not easy to impact the normal use of railway.
The present invention is further arranged to: being needed to be prepared work before the step a, is checked inflating machine and changer is
No there are failures, and provide 380V alternating current for inflating machine and changer, and whether check has enough liquid in fluid reservoir
Carbon dioxide checks whether the corresponding consumptive material of fracturing device is sufficient；Then the works such as multimeter, pliers, spanner and interior hexagonal are checked
Whether complete have.
By using above-mentioned technical proposal, check equipment with the presence or absence of failure and check it is complete when consumptive material and tool,
It can guarantee going on smoothly for work progress, prevent from influencing construction because of the equipment fault either shortage of consumptive material and tool
It is normally carried out.
The present invention is further arranged to: in the step a, when conducting wire is passed through liquid storage pipe, first being put fracturing device liquid storage pipe
On display rack, iron wire is inserted into liquid storage pipe, and makes one end of iron wire buckle from one end that liquid storage pipe is carved characters
It stretches out, then catches on the conducting wire of heating device with one end of iron wire buckle and pull iron wire, so that conducting wire is from the another of liquid storage pipe
It is stretched out in one end.
By using above-mentioned technical proposal, conducting wire is pulled to pass through in liquid storage pipe by the iron wire of buckle, it can be to leading
Line guides, and enables conducting wire to pass through liquid storage pipe more convenient.
The present invention is further arranged to: in the step a, when tightening to release pipe and filling valve, first by hand
The fracturing device that work is twisted is placed on changer jaw, and is filled with one, valve and is inserted into dismounting in front；It pins and clamps button to pressure
Power, which rises to unclamp after 10MPa or more, clamps button, when then pinning fastening buttons pressure being made to rise to 10MPa, decontrols tight
Gu button；Then fracturing device is turned around, repeated presses clamp button and fastening buttons, so that pressure is risen to 10MPa respectively.
By using above-mentioned technical proposal, by controlling the range of pressure, release pipe and filling valve can either be tightened, again
It can prevent the helicitic texture for excessively tightening and destroying junction.
The present invention is further arranged to: in the step b, being deflated, will entirely be managed before working for the first time daily
Evacuating pipeline, when exhaust, first open inlet ball valve and vent ball valve in filling station, release button are then pressed, until vent ball valve
After spraying continuously white gas, vent ball valve is closed.
By using above-mentioned technical proposal, deflation processing is all carried out before working for the first time daily, can prevent from having in pipeline
Other remaining gases, so that carbon dioxide gas can be full of in pipeline.
