3/ h.When trying pore-forming and soil layer grittiness is larger, between circulatory pool 6 and stake holes, be also provided with a slurrying pond (not shown), slurrying pond is communicated with circulatory pool 6.
Embodiment two
Continuing composition graphs 2 below specifically utilizes Pump breath countercirculate construction equipment to carry out the method for bored pile pile foundation construction.Bored pile pile base construction method, comprises the steps:
Step one, provide a Pump breath countercirculate pile foundation construction device, and debugging prepares, and arranges mud circulating system simultaneously.
Pump breath countercirculate pile foundation construction device comprises the convolution rig 1, reacting cycle gravel pump 2, slag absorbing flexible pipe 3, mud purifying device 4, sedimentation basin 5 and the circulatory pool 6 that are communicated with successively, convolution rig 1 comprises drill bit 10, drilling rod 11, drive link 12, rotating disc 13, hydraulic motor 14 and the base 15 be arranged at above pile foundation, base 15 is provided with the through hole passed for drive link 12, hydraulic motor 14 is located on base 15, Flange joint is passed through in the bottom of drill bit 10 and drilling rod 11, the top of drilling rod 11 and the bottom Flange joint of drive link 12, the top of drive link 12 is passed rotating disc 13 and connects and fixes, the top of drive link 12 is flexibly connected with the side of reacting cycle gravel pump 2 by swivelling union 7, reacting cycle gravel pump 2 and slag absorbing flexible pipe 3 junction are provided with water tap 21, slag absorbing flexible pipe 3 respectively with water tap 21, mud purifying device 4 is fixedly connected with, hydraulic motor 14 drives rotating disc 13 to rotate.Mud circulating system method to set up is: first arranged in sedimentation basin 5, circulatory pool 6 and slurrying pond (not shown) point storehouse, the capacity in each storehouse should meet the needs of construction period mud sediment amount, and removes sediment in storehouse in time.Secondly, circulating mud need by the mud purifying device 4 arranged above circulatory pool 6, to reduce sand factor.3rd, flowing through the length of route by increasing circulating mud, reducing the content of Extra-fine sand in mud further.So far, the preparation of drilling construction completes.
Step 2, first drill bit 10 is increased to 30 ~ 50cm place at the bottom of distance stake holes, and in stake holes, injects a certain amount of mud, then start reacting cycle gravel pump 2 and rotating disc 13, and reacting cycle gravel pump 2 is dallied certain hour, until formation reacting cycle.
Step 3: start to creep into after reacting cycle to be formed, until form stake holes.
Specifically, according to different geology characteristic, choose reasonable drilling parameter, for argillic horizon, should use medium-to-high grade, suitably reduce the pressure of the drill, accelerates rate of penetration, such as: 40 ~ 70 revs/min.For sandy soils, should use low and middle-grade, suitably increase the pressure of the drill, slow down drilling speed, such as: be less than 40 revs/min.Meanwhile, the mud flowed to after circulatory pool 6 purifies in stake holes forms mud off.The quality of quality of mud fluid directly has influence on the performance of hole quality and bearing capacity of pile foundation.Owing to intending there is thicker silty sand ground in stratum, construction drill castinplace pile pile foundation place, for reducing the situation of hole wall collapse and necking down, in mud off, the proportion of mud is 1.10 ~ 1.15, and viscosity is 20 ~ 25s, sand factor < 5%.And, when the boring mud amount that reacting cycle gravel pump 2 is discharged reduces or in water outlet, dregginess is more, should rate of penetration be controlled.The rig 1 that circles round during perforate gently presses slow-speed, increases and suitably increases pressure and speed, adopt denseer mud off, and slow down rate of penetration and rotating speed when soil property unconsolidated formation along with the degree of depth, and the slow-motion of light brill is to control collapse hole.After subject-oriented position or drill bit 10 all enter stratum, can accelerate to creep into.
Step 4: after stake holes is formed, carries out hole construction clearly.
The construction of clear hole is carried out at twice, and first time, clear hole was carried out after pore-forming, and the clear hole of second time is carried out after reinforcing cage and catheter installation.For effective cleaning hole bed mud sand, secondary pile hole cleaning all adopts Pump breath countercirculate technique.
Clear hole construction sequence:
The first step: after stake holes is formed, drill bit 10 is mentioned 45cm ~ 55cm, and keep the normal circulation of mud, the mud that proportion is 1.05 ~ 1.15, viscosity is 17 ~ 20s is made to flow in stake holes, keep stake water level in borehole to exceed more than groundwater table 0.5m simultaneously, until fill stake holes, complete first time clear hole construction.That is, carry out first time clear hole behind whole hole immediately, special messenger should be provided with in the process of clear hole and fish for boring mud, to accelerate the speed in clear hole.The clear hole time is as the criterion to have changed magma in hole, and makes mud Indexs measure at any time, and sampling should be carried out from plasma discharge mouth, the same magma of mud index.During clear hole, in boring casing, mud water level should be noted keeping stable, to prevent drill hole caves.The clear hole time determines according to measuring precipitation thickness in mud balance and clear hole process, clear hole time controling formula: h=V/Q, wherein: the h-clear hole time; V-stake holes volume, Q: reacting cycle gravel pump flow.Drill bit is carried to about 0.5m at the bottom of hole by first time clear Kong Shiying, and in the hole when of clear hole, input mud amount should not be less than reacting cycle gravel pump discharge capacity, ensures the mud amount of supplying, answers conservative control pump amount simultaneously, avoids inhaling collapse hole wall.
Second step: until after having laid reinforcing cage and conduit in stake holes, carries out second time clear hole construction according to the method for the described first step.
After completing twice clear hole, in mud off, the proportion of mud is 1.05 ~ 1.10, viscosity is 17 ~ 20s, sand factor < 1%, sediment thickness < 0.2D (D is the diameter of bored pile), vertical degree of the peg hole < 1%.
In sum, Pump breath countercirculate pile foundation construction device of the present invention, is applicable to carry out drilling pouring pile hole construction in deep powder sand soil.Pump breath countercirculate pile foundation construction device comprises the convolution rig, reacting cycle gravel pump, slag absorbing flexible pipe, mud purifying device, sedimentation basin and the circulatory pool that are communicated with successively.By be arranged at convolution rig drive link above reacting cycle gravel pump pump-absorb action convolution rig drilling rod inner chamber formed negative pressure, in stake holes under fluid column and atmospheric effect, at the bottom of the mud flow stake holes of stake holes wall and annulus, the boring mud that gets off of bit cutting of convolution rig is brought into the drilling rod inner chamber of convolution rig, then to drain into after mud purifying device carries out desanding through reacting cycle gravel pump with the mud of boring mud and enter the sedimentation basin being positioned at ground again.Remove the mud after boring mud in sedimentation basin by slush pump pump people circulatory pool, the mud after circulatory pool purification is flowed in stake holes by chute again, thus forms reacting cycle.In deep silty sand ground bored pile construction process, when adopting Pump breath countercirculate pile foundation construction device of the present invention to carry out pore-forming and clear hole, the pore-forming time shortens greatly, and mud balance, sand factor, sediment at the bottom of hole can better be controlled, and make pile quality have abundant guarantee.Bored pile construction method, by arranging reacting cycle gravel pump, greatly shorten whole pumped loop, reduce the power of gravel pump, improve the suction to mud in hole and boring mud, accelerate speed of fulfiling hole, thus solve in traditional normal circulation technology high to the power requirement of gravel pump, whole pumped loop needs airtight, the not high and problem that electric quantity consumption is large of pore-forming efficiency.
