Technical solution of the present invention is described in detail with specifically embodiment below.These specific implementations below
Example can be combined with each other, and the same or similar concept or process may be repeated no more in some embodiments.
Fig. 1 is the flow chart of the construction method that water-stop curtain pile foundation is built using waste mud in the embodiment of the present invention one,
Fig. 3 is the first stake holes and the first pile foundation overlooking structure diagram in the embodiment of the present invention one.
Construction method provided in an embodiment of the present invention using waste mud construction water-stop curtain pile foundation.As shown in Figure 1, this reality
The construction method for applying example includes:
S1, the first stake holes 1 is drilled with using mud.
For example, in step S1, the soil of the predetermined position of the first stake holes 1 is dredged using machinery equipment
Pine, by a part of slurry prime in the predetermined position, carries out in the soil of loose predetermined position to the predeterminated position
When boring stake holes, ordinatedly it is lower can Automatic-seepage water also be understood as waste mud so as to form moist mud, waste mud relative to
Dry soil is easier that the first stake holes 1 is discharged, and is also beneficial to the subsequent borehole cleaning to the first stake holes 1 and operates.
S2, mud in the first stake holes 1 is extracted to dirty mud sump.
For example, in step S2, useless mud will be discharged into after the waste mud extraction in the first stake holes 1 using machinery equipment
In stock tank, keep the first stake holes 1 vacant, to provide space for perfusion liquid concrete, wherein dirty mud sump is arranged in sealing
Curtain areas adjacent, in order to the transport operation in subsequent step.
S3, desanding processing is carried out to the waste mud in dirty mud sump and obtains pure mud.
For example, in step S3, using machinery equipment by waste mud drilling cuttings and sand clear out of waste mud, from
And pure mud is formed, when the amount of drilling cuttings and sand in waste mud, the drilling cuttings and sand that contain in mud is more, it can reduce
The viscosity of concrete is prone to wear machinery equipment when utilizing slurry manufacture concrete using machinery equipment.
S4, pure mud is sent into stirring pool.
For example, in step S4, the pure mud after desanding step is sent into stirring using machinery equipment
In pond, stirring pool is used to a variety of materials mixing stirring liquid concrete is made, and waste mud is fully utilized, is kept away
Exempt from all to transport outward waste mud, can reduce environmental pollution, and has saved manpower and material resources spent by outward transport mud.
S5, cement is injected into stirring pool.
For example, in step S5, when making liquid concrete, can be in the quality of addition cement and the specific gravity of mud
0.2,0.25 or 0.4, the intensity and water-stagnating effect after manufactured liquid concrete solidification are good.
S6, it stirs to obtain the mixed liquor of cement Yu pure mud.
Specifically, in step S6, using machinery equipment to the mixed liquor of cement and pure mud in stirring pool
It is stirred, is sufficiently mixed cement with pure mud, to be ready for subsequent production liquid concrete.
S7, cement slurry is extracted to the first stake holes 1, stirring is to be uniformly mixed, to solidify to form the first pile foundation 11.
Specifically, in step S7, after cement slurry to the first stake holes 1, cement slurry is in the first stake holes 1 with the time
Passage, slurry have gradually lost plasticity, have become not flowable close state, hereafter the intensity of slurry gradually increases, directly
It can become the stone shape solid with suitable intensity to the end, to form the first pile foundation 11.
Through the above it is not difficult to find that the construction party provided by the invention using waste mud construction water-stop curtain pile foundation
First the mud extracted out out of first stake holes 1 progress desanding is largely utilized when making liquid concrete by removing for method
Mud after sand avoids and all transports outward waste mud, so that manpower and material resources are saved, meanwhile, greatly reduce waste mud
Pollution to environment, it is environmentally protective.

Stake holes 1, in the soil of loose predetermined position, the single-shaft-rotation speed of 40r/min~60r/min can prevent soil from splashing
To around the first stake holes 1, due to underground meeting Automatic-seepage water, so as to form waste mud, waste mud is easier to arrange relative to soil
First stake holes 1 out, to form the first stake holes 1, to the subsequent operation for emptying the first stake holes 1.
Optionally, in the present embodiment, in step s 2, specifically includes the following steps:
S2001, mud is injected in the first stake holes 1 by borer drill rod using the first slush pump；
S2002, drilling tool is protruded into the first stake holes 1, and controls drilling tool rotation；
S2003, promotion and sinking drilling tool, clod and sediment for taking out of in the first stake holes 1；
S2004, it proposes drilling tool and transfers conduit；
S2005, mud is evacuated in waste pulp pond by the mud that conduit injects in the first stake holes 1 using the first slush pump.
When repeatedly being promoted with sinking drilling tool, clod and sediment can be made to mix more evenly, be conducive to clear up the first stake holes 1 more thorough
Bottom.
Optionally, in the present embodiment, further comprising the steps of after step S2005:
S2006, mud is injected in the first stake holes 1 by the aperture of the first stake holes 1 using the first slush pump；

S2008, promotion and sinking drilling tool, mud takes first out of by high pressure slurry pump out of drilling rod in the first stake holes 1
Clod and sediment in hole 1；
S2009, after inner hole deposition slag is met the requirements, lift drilling tool；
S2010, mud is injected in the first stake holes 1 using the first slush pump, mud passes through the first mud in the first stake holes 1
Pump takes clod and sediment out of out of first stake holes 1.When repeatedly being promoted with sinking drilling tool, clod and sediment can be made to mix more equal
It is even, be conducive to clear up the first stake holes 1 more thorough.
Optionally, in the present embodiment, in step s 2, specifically includes the following steps:
S221,1 inner surface of the first stake holes being carried out using the first water pump to wash away water filling, water injection pressure is 0.3~0.6Mpa,
And the water filling water surface is lower than the first stake holes 1, to obtain dilution mud；
