Description
Technical field
The present invention relates to the construction method that sand content in mud is controlled in a kind of filling pile construction.
Background technology
With the development of infrastructure, bored pile construction is widely used, wherein influenceing cast-in-situ bored pile matter
The mud property index request more and more higher of amount.Sand content in mud refers to that the sand grains in mud more than 74um accounts for mud cumulative volume
Percentage composition, the main function of mud is retaining wall, takes slag and cooling and lubricating effect, when under the high speed conditions of drilling rod, mud contains sand
It is serious to slush pump, drilling rod and bit wear when rate is high, therefore provide that sand content in mud can not be more than 4%, and in drilling process
Desanding purification work need to be carried out.For complicated geological soil layer, during as carried out cast-in-situ bored pile construction in peat soil layer, mud
Proportion, viscosity and sand factor control it is difficult, cause the filling pile construction time greatly to extend, complete one within average 10 days or so
The construction of stake, efficiency of construction is seriously reduced, improve construction cost.
For filling pile construction, traditional construction technology be measure of pile position unwrapping wire, the interim casing of installation, drilling rod perforate, into
Hole, judge that drill bit enters rock scar, whole hole, then first time slush pump reacting cycle borehole cleaning 24~48 hours and detect mud index,
Screwing steel bars cage is simultaneously transferred in hole, and second slush pump borehole cleaning 5~6 hours simultaneously detects mud index, is adopted after casting concrete
With ultrasound examination, filling pile construction is completed.By traditional construction technique, filling pile construction pore-creating is smooth, but mud contains behind whole hole
Sand coarse aggregate ratio difficulty up to standard, first time borehole cleaning overlong time is caused to reach 48 hours or so so that the single filling pile construction duration
Long, filling pile construction speed is slow, has a strong impact on filling pile construction progress.According to bored concrete pile circular bit mud endless form
Difference, circular bit is divided into direct circulation drilling and reverse circulation drilling.Direct circulation is that flushing liquor is sent by slush pump by drilling rod
Enter bottom hole, then by bottom hole out of hole on return to ground；Reverse circulating flushing liquor is just opposite with the route of direct circulation.Bored concrete pile rushes
Hit pore-forming drill and mud borehole cleaning is mainly carried out using direct circulation, the direct circulation impact holing technological operation is simple, is adapted to various soil
Layer filling pile construction, enters rock and cuts that rock speed of application is fast, and filling pile construction quality is good, and construction input cost is low；Reverse circulation drilling is only
Suitable for circular bit, circular bit construction input cost is very high, and the very slow rock sample sometimes of rock drilling layer can not take out, no
It is adapted to construct at layer of sand, is only suitable for argillic horizon and friction-type filling pile construction.
The content of the invention
The technical problems to be solved by the invention are to provide the construction party that sand content in mud is controlled in a kind of filling pile construction
Method, sand content in mud meets construction requirement when this method ensure that bored concrete pile borehole cleaning, shortens the bored concrete pile borehole cleaning time, accelerates perfusion
Pile driving construction speed, filling pile construction quality is improved, reduce construction cost.
In order to solve the above technical problems, the construction method of sand content in mud is controlled in filling pile construction of the present invention including as follows
Step：
Step 1: being irrigated a measure of pile position unwrapping wire according to design drawing, interim casing is installed, its position is checked simultaneously
Increase fender pile；
Step 2: stake machine starts to construct, percussion drilling pore-forming technique is taken to be constructed, mud off；
Step 3: carrying out drive sampling according to speed of fulfiling hole, with reference to geological prospecting borehole data, judge to creep into soil layer type, sentence
Determine drill bit and enter rock scar, it is determined that entering rock depth, whole hole is crept into according to rock depth is entered；
Step 4: carrying out first time borehole cleaning using direct circulation using mud separator and slush pump behind whole hole, while process steel
Muscle cage, and sand content in mud, viscosity and proportion index are detected, 5~7 hour sand factors of borehole cleaning reach 3%, use mud again afterwards
Stock pump direct circulation borehole cleaning 2~3 hours to mud balance reaches 1.15~1.2g/ml, 30~40s of viscosity, sand factor 2%, completes the
Borehole cleaning；
Step 5: installing steel reinforcement cage using loop wheel machine merogenesis, steel reinforcement cage is carried out clear for the second time using slush pump direct circulation after installing
Hole 1~2 hour, detection mud balance reach 1.10~1.15g/ml, 30~40s of viscosity, sand factor 2%, complete clear for the second time
Hole；
Step 6: using tremie placing concrete, ultrasonic wave integrity test detection, the qualified completion of testing inspection are carried out after 7 days
Filling pile construction.
Further, the direct circulation borehole cleaning irrigates mud into drilling using slush pump, by the midge of mud separator
Mud in mouth suction drilling, sand grains flows out from sand export after separation, and slurries flow to sedimentation basin from overfall mouth, and slurries are after precipitation
Into mud pit.
Due to controlling the construction method of sand content in mud to employ above-mentioned technical proposal, i.e. this method in filling pile construction of the present invention
Measure of pile position unwrapping wire is carried out first, interim casing is installed, and drill perforate, pore-forming, judges that drill bit enters rock scar, whole hole, Ran Hou
First use mud separator and slush pump borehole cleaning be after 5~7 hours, then using 2~3 hours of slush pump direct circulation borehole cleaning simultaneously
Detect mud index, screwing steel bars cage transfers steel reinforcement cage, and second using slush pump borehole cleaning 1~2 hour and detects mud and refer to
Mark, using tremie placing concrete, ultrasound examination is carried out after 7 days, completes filling pile construction.This method ensure that bored concrete pile is clear
Sand content in mud meets construction requirement during hole, shortens the bored concrete pile borehole cleaning time, accelerates filling pile construction speed, improves bored concrete pile and applies
Working medium amount, reduce construction cost.
