Forcible entry process is more safe and reliable.
It should be noted that the execution sequence between step S10, step S20 and step S30 is intended only as a kind of example,
It is not specific.Specifically, those skilled in the art can replace the execution between these three steps according to actual conditions
Sequentially, or at the same time these three steps are performed.It should also be noted that, when the area that airfield runway needs dismantle is larger,
Pillar hydraulic pressure in more sets of holes can be used to split stone implement equipment, constructed at the same time on the coating above matrix to be repaired.
Specifically, step S30 further comprises：
The dbjective state of coating spalling peeling is determined according to several the first operation holes；
The number and orientation in basic hole are determined according to dbjective state.
By the setting in basic hole, the scope of freedom for being used for realization first spalling is formed.After the completion of first spalling, shown on runway
The scope of freedom can be so produced, therefore no longer needs basic hole to assist spalling.

Step S50, the second hole group is formed on region to be dismantled, the second hole group includes matched with second group of expansion gear
Several the second operation holes；
Step S60, second group of expansion gear is inserted into pillar hydraulic pressure in corresponding second operation hole Zhong Bingshi holes and splits stone implement
Action, so as at least one the second crackle of formation on region dismantle；
Repeat step S50 to S60, until the coating in region to be dismantled can be removed.As can be seen that pass through each expansion
The area that spalling crushes, is gradually completing forcible entry task, and entirely dismantle process is easy to operate, and spalling process is shockproof, noise,
Dust and slungshot, construction safety, forcible entry operation do not influence the Aerodrome Operations activity of surrounding, improve forcible entry efficiency and airfield runway
Operation ability.Furthermore, it is possible to splitting stone implement only with pillar hydraulic pressure in a hole completes above-mentioned forcible entry, can also be according to reality
Demand introduces pillar hydraulic pressure in Duo Tai holes and splits stone implement, while constructs in multiple regions to be dismantled.Pillar hydraulic pressure splits stone implement and applies in hole
Work is flexible, has good adaptability.
It should be noted that need to predict this in the case of in region to be dismantled with non-maintenance area being connected, before spalling

As a preferred embodiment, aperture of the aperture in the second operation hole equal to or different from that the first operation hole.First crackle will
Coating above matrix to be repaired be divided into it is multiple after region is dismantled, using the second operation hole aperture be equal to first make
During the aperture in industry hole, the expansion gear and drill bit for replacing different-diameter in the construction process are avoided, improves the efficiency of forcible entry.
The area in region to be dismantled is less than the area of the coating above initial matrix to be repaired, so in the region of forcible entry small area
When, it can also use the expansion gear smaller than the diameter of first group of expansion gear.On the one hand it is convenient in small area region to be dismantled
Upper precise manipulation, on the other hand saves the energy.Obviously, the aperture in the second operation hole can also be more than the hole in the first operation hole
Footpath.
As a preferred embodiment, the aperture in basic hole is equal to the aperture in the first operation hole.Avoid and replace in the construction process
The drill bit of different-diameter, improves forcible entry efficiency.Obviously, the aperture in basic hole may also be distinct from that the aperture in the first operation hole,
Those skilled in the art can make rational matching and selection according to practice of construction situation to the aperture in various holes.
As a preferred embodiment, the first operation hole, the second operation hole, basic hole and limiting holes can be formed using drilling machine,
Such as drilling machine can be hydraulic drill rig, down-the-hole drill or air drill.Since drilling machine can produce solid in boring procedure
Particle and dust, therefore, drilling machine preferably selection and deployment have the drilling machine of dust collecting, for example, dust collecting can be with
It is bag filter.
As a preferred embodiment, first group of expansion gear includes first group of expansion housing and is arranged in first group of expanding shell body
First group of expansion tube, first group of expansion housing is two-flap type structure；Second group of expansion gear include second group of expansion housing and
Second group of expansion tube being arranged in second group of expanding shell body, second group of expansion housing are multi-clove type structure.Need to illustrate
Although second group of expansion housing is multi-clove type structure, but it is clear that two-flap type expanding shell body can be such that the bulbs of pressure more collect
In, spalling degree bigger.Therefore in order to improve forcible entry efficiency, a kind of scheme being more highly preferred to is the institute in the forcible entry of airfield runway
The expansion housing used is two-flap type expansion housing.Obviously, first group of expansion housing and second group of expansion housing can also be equal
For the multi-clove type structure more than two valves.For example, enclose the peripheral layout arranged on one or a set of operation hole in several basic holes
Under mode, expansion housing can be the multi-clove type structure more than two valves.But when the forcible entry operation of airfield runway is larger, use
Multi-clove type more than two valves expands housing, and forcible entry efficiency is low and is unable to the swollen direction of check of accurate judgement.The housing pair of different flap-type
The direction for the bulbs of pressure that operation hole wall produces is different.It is understood that those skilled in the art can be according to forcible entry object
