High-voltage tube 22 is put into main working hole 991 again after fixation, sealing mainboard is finally fixed on bored concrete pile.
By high pressure slurries device 2 to main working hole 991 carry out inject high pressure slurries rejected region is removed when, inject
Slurries and wash away out sediment mixing after rise along main working hole 991, discharged from the slurry outlet 12 of main working hole 991.
When rejected region position is in it is deeper when, the mud that is sprayed to the nozzle 25 of high pressure slurries device 2 of mud in drilling 99
Slurry effect generation reduces effect so that the souring of high-pressure slurry weakens, it is therefore desirable to uses up the mud water level in drilling 99
It may reduce.Solution be select with main working hole 991 similar in a drilling 99 as back work holes 992, to ensure
High pressure slurries device 2 effectively washes away scope, avoids removing interlayer and sediment is omitted, using gaslift decompressor 3 to backman
That makees the operation of hole 992 realization raising cement mortar washes away stress problems.
Specifically, the structure of gaslift decompressor 3 is only by high pressure mud using identical with the structure of high pressure slurries device 2
Stock pump 21 replaces with air compressor machine 31, i.e. gaslift decompressor 3 includes air compressor machine 31, high-voltage tube 22, fixing device 23, injection nozzle carrier 24
And nozzle 25, the structure and annexation between part are consistent with high pressure slurries device 2, and this is no longer going to repeat them.
During work, by entering for the output end of gaslift decompressor 3 and the sealing mainboard 1 that is fixed on back work hole 992
Slurry hole 11 connects so that and air compressor machine 31 is interior to back work hole 992 to input compressed air, compressed air and slurries gas-liquid mixed,
Mixed gas-liquid unit weight is less than volume weight of slurry, can quickly float along back work hole 992 and be discharged from slurry outlet 12, make
Slime water potential drop is low in drilling.
In site construction, because the mud spent by removing stage is very more, in order to avoid contaminated site, be advantageous to ring
Protect, it is possible to recycled the mud that removing stage is discharged.
Specifically, also including overflow circulating apparatus 4, overflow circulating apparatus 4 is mud cleaner, and overflow circulating apparatus 4 is defeated
Entering end can connect with slurry outlet 12, and output end connects with the input of high pressure slurry pump 21.During work, overflow circulating apparatus 4
Input can be respectively with main working hole 991 and back work hole 992 slurry outlet 12 connect, so, main working hole 991 or
The mud that person's back work hole 992 is discharged can be flowed into overflow circulating apparatus 4, be input to again in high pressure slurry pump 21 after purification
Recycle.
After the completion of interlayer and pile bottom sediment in pile body are removed, the mud of the removing of high pressure slurry pump 21 is changed into height
In the cement mortar of one label of pile concrete, continue to inject to pile body inside, now by the input of overflow circulating apparatus and
Output end distinguishes slurry outlet 12 and high pressure slurry pump 21 disconnects, and all hole positions of pile body is fully open, observes from main work
Whether the cement mortar for making hole 991 and the slurry outlet 12 in back work hole 992 and other spillings of drilling 99 is dense with the cement mortar of input
Degree is consistent, such as it is basically identical, simultaneously close off high pressure slurries device 2 and gaslift decompressor 3 and will both from pile body dismounting.Will
The output end of high pressure slurry pump 21 directly directly connects with slurry-feeding hole 11 or with slurry outlet 12, and remaining aperture of pile body is whole
Block, start high pressure slurry pump 21 and pile body inside is continued to inject cement mortar, high pressure slurry pump 21 is closed after maintaining a period of time,
After cement mortar consolidation, it is standby that all sealing mainboards 1 and device are removed into storage.
It should be noted that when high pressure slurry pump 21 connects with slurry-feeding hole 11, the base of fixing device 23 can be used
The output end of high pressure slurry pump 21 is carried out closed connect by 231 with 22 identical connected mode of high-voltage tube with slurry-feeding hole；When high pressure mud
When the output end of stock pump 21 connects with slurry outlet 12, it can be connected and sealed by jointing, overflow circulating apparatus is with going out
Starching the connection in hole 12 can also use jointing transition seal to connect, and can also use other modes, not limit herein.
The utility model additionally provides cast-in-situ bored pile interlayer and sediment is removed and reinforcing construction method, including following step
Suddenly：
S1：To check and accept underproof pile body drilling 99 or by the use of drilled drawing-core detect when drilling 99 be used as work
Hole, the quantity of working hole is determined according to pile body diameter size；
S2：If the more similar drilling 99 of two distances is selected between dry hole 99 as main working hole 991 and auxiliary
Working hole 992, sealing mainboard 1 is sealingly fastened in the top in main working hole 991 and back work hole 992 respectively, remaining drilling
99 carry out sealing closing；
S3：Start high pressure slurries device 2 to sink to pile body inside interlayer or stake bottom to main working hole 991 input high pressure slurries
Slag is washed away, while it is abundant with mud to input compressed air, sediment in back work hole 992 to start gaslift decompressor 3
The slurry outlet 12 for sealing mainboard 1 after mixing along main working hole 991 or the top of back work hole 992 is net into overflow circulating apparatus 4
Enter high pressure slurry pump 21 after change, so circulation can pass through up to the sediment of interlayer or bottom is cleaned out and analyze what is returned
In mud silt content come differentiate sediment and clamping cleaning degree；
S4：S2-S3 steps are repeated according to two other the replaceable drilling 99 of the size in stake footpath, until by the interlayer of pile body and
Pile bottom sediment cleaning is completed；
S5：After interlayer and pile bottom sediment are cleaned out, change the mud that the scarfing cinder of high pressure slurry pump 21 uses into label and be higher than
The cement mortar of one grade of pile body concrete grade, the mud that cement mortar is carried out in pile body is injected into main working hole 991 and is replaced,
The connection of overflow circulating apparatus 4 and drilling 99 is disconnected and opens all apertures simultaneously, until the cement that aperture gushes out
Slurry concentration approaches with the cement mortar injected；
S6：Slip casting is replaced, and takes out the equipment of high pressure slurries device 2 and gaslift decompressor 3 in drilling 99,
The output end of high pressure slurry pump 21 is directly connected with slurry-feeding hole 11 or slurry outlet 12, remaining aperture seals closing, high pressure
Slush pump 21 continues to inject cement mortar into working hole, the cement mortar pressure in working hole is maintained under setting pressure, maintains
After certain time, high pressure slurry pump 21 is closed, after cement mortar final set in working hole, removes sealing mainboard 1.
Wherein, in step s3, passed through after sediment and mud are sufficiently mixed and mud is entered by the slurry outlet 12 of main working hole 991
Slurry clarifier 41 is output in high pressure slurry pump 21 after purifying；Make winner's working hole 991 and auxiliary when interlayer or sediment are washed
When helping the bottom of working hole 992 identical logical, the compressed air gas-liquid mixed that is sprayed in slurries and gaslift decompressor 3 so that mixing
Gas-liquid afterwards enters mud cleaner 41 from the slurry outlet 12 in back work hole 992.
The above is only some embodiments of the present utility model.For the person of ordinary skill of the art, not
On the premise of departing from the utility model creation design, various modifications and improvements can be made, these belong to the utility model
Protection domain.
