Technical field
The present invention relates to bored pile construction field, the place of burying in especially a kind of drill-pouring work progress mesopore
Reason method.
Background technology
Using percussive drill coating in carry out bored pile construction when, due to around hole wall soil layer it is uneven
Property, collapse hole accident often occurs.In generation hole during collapse hole accident, if drill bit can not take out in time in hole, often occur
Underground drilling accident.Traditional treatment method is to use the timely borehole cleaning of air compressor machine, then acts method of pulling out using strength, explosion rises and pulled out at method
Reason, but for collapsed in hole collapse that thing is more and dilapidation based on block stone, rubble and sandy gravel, drill bit buried depth it is larger when, take
The method of stating is difficult to success.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of processing side of burying in drill-pouring work progress mesopore
Method, can solve the problems, such as that coating occurs burying and can not taken out, operation is simple, without the use of large scale equipment, drops significantly
Low cost.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of drill-pouring work progress mesopore
The processing method of interior burying, this method comprise the following steps：
Step 1：During bored pile construction, after underground drilling accident in hole occurs for drilling, first according to suspension drill bit
Mark on steel wire rope, determine that drill bit is embedded in the depth H in hole；
Step 2：The hole depth after collapse hole occurs is measured with lining rope in aperture, determines the depth h that drill bit is buried by dilapidation；
Step 3：The steel wire rope of suspension drill bit is cut off in aperture, steel wire rope is divided into the first steel wire rope and the second steel wire rope, and will
First steel wire rope of suspension drill bit is suspended on drilling machine mast with guide chain cucurbit, and drill bit is in upward stress；
Step 4：Small drill bit is hung on the second steel wire rope, and guider is set up with the lumps of wood in aperture, changes the second steel wire rope
Direction, small drill bit is down crept into along hole wall side, drilling depth exceed institute's burying head bottom；
Step 5：Small drill bit is proposed, is positioned over outside drilling, small draw tube will be hung on draw tube hoisting rope, to the small drill bit of step 4
Slagged tap in the hole drilled out；
Step 6：Repeat the above steps 4 and 5, then the drill two holes around hole wall, and above-mentioned two hole is together with the hole that step 5 obtains
Arranged in equilateral triangle；
Step 7：The small drill bit hung on second steel wire rope is replaced by flat chisel, removing small drill bit around hole wall using flat chisel does not have
The sediment in place is got into, and the small draw tube 10 on draw tube hoisting rope is put to cleaning eye bottom sediment in hole；
Step 8：Flat chisel is unloaded, the guider in aperture is removed, fixes percussive drill, by the first steel wire rope and the second steel wire rope
Connection forms steel wire rope, is lifted up drill bit, drill bit is in maximum weighted state；
Step 9：Small draw tube on draw tube hoisting rope is unloaded, changes small drill bit, transfers to bottom hole, then lifting is small up and down
Drill bit, pound to the drill bit being embedded in hole, make to shake caused by it, loosen the soil layer around bottom hole drill bit；
Step 10：Pounding into hole during drill bit, observing the mark situation of change on steel wire rope, up moved when marking,
Then continue up to lift drill bit, be at maximum weighted state, then continue down to pound repeatedly to drill bit using small drill bit, directly
It can be taken out completely to drill bit；
Complete the processing of burying.
Small drill bit is the drill bit of 30 centimetres of diameter.
Small draw tube is the draw tube of 25 centimetres of diameter.
The processing method of burying in a kind of drill-pouring work progress mesopore provided by the invention, using small drill bit, flat chisel
And small draw tube removes the dilapidation around drill bit, condition is created for processing burying；Up lifting hole subdrilling head, is at most
Big upward stress, drill bit in hole is down pounded by small drill bit repeatedly, is made to shake caused by drill bit, is loosened bottom hole drill bit week
The soil layer enclosed, reach the purpose for taking out drill bit；Can solve the problems, such as that coating occurs burying and can not taken out, it is simple to operate easy
OK, without the use of large scale equipment, cost is greatly reduced.
