7 borehole wall causes wide-angle tilt in sinking watching.
It is 14.4m to diameter below in conjunction with attached drawing, depth is the rotation of 20m to make technical characterstic be easier to be understood
The arrangement and method for construction of stream well is described in detail:
In the present embodiment, it is 14.4m that open caisson ontology 7, which is diameter, and depth is the whirling well of 20m;Clear water storage facilities 4
As clear water reserviors;Settling apparatus 8 is mud-settling pit;Hydraulic giant 2 selects flushing cinder giant;Slush pump 6 selects high-power mud
Stock pump.
One, the preparation before constructing:
1, the operating platform in whirling well is set up, operating platform can utilize scaffold building, and operating platform is fixed on eddy flow
On the pre-buried I-steel of the well borehole wall or C-type steel.As shown in Figure 2.
2, flushing cinder giant is installed, is put into water pump under clear water reserviors, and prepare sufficient pipeline, connection clear water reserviors to eddy flow
Well, makes dewatering well near whirling well, and dewatering well facilitates whirling well to settle for the water near the whirling well that shuts off.
On 2.1 installation 22KW high powered water pumps 1 to floating drum, it need to ensure the depth in water pump insertion mud, prevent water level
The accidents such as unloaded, the stifled pump occurred when too low or excessively high and click water inlet.As shown in Figure 3.
2.2 are entered in whirling well with crane lifting slush pump, and riding position ensures mud in whirling well in centre in well
Medial Convergence, uniform drainage subsidence.
The control electronic box for installing flushing cinder giant and slush pump above the 2.3 whirling well boreholes wall at extension, is responsible for by special messenger
It commands and observes inclination of open caisson angle.
3, the Earthwork Calculation that sedimentation basin can be unearthed every time according to whirling well, volume are preferably 1.5-2 times of the amount of being unearthed, example
Such as: the earth volume that whirling well is unearthed every time is about 900m3, then the volume of sedimentation basin is about 1400m3.The shape of sedimentation basin is preferably to grow
It is rectangular, it can ensure that mud sufficiently precipitates and transport outward native condition.Clear water reserviors volume is 40m3, need to ensure flushing cinder giant water
Amount is sufficient.
4, precipitation well construction, according to live level of ground water and seasonal rainwater, using tube well dewatering, well depth 30m amounts to
It 20, is uniformly distributed in the border 5m outside the whirling well borehole wall.
Two, the unearthed work progress of flushing cinder
The present embodiment mainly in the main structure for the coordinate control point production whirling well having good positioning, is set to superstructure satisfaction
After counting intensity and code requirement, sinking construction is carried out.The following steps are included:
1, levelling of the land.
2, basement process.
3, well bore measurement and positioning.
4, blade foot makes.
5, wellbore section pours.
6, flushing cinder is unearthed:
6.1, the assembling slush pump in advance before flushing cinder is unearthed, is secured to two floating drum centers, and with 25T crane handling
The low-lying place of centre in whirling well well.
6.2, operating platform is set up using the steel pipe of Φ 48*3.5mm, be fixed in whirling well well in I-steel or C-type steel
Side, steel tube lapping length >=600mm are reinforced using double fasteners.Operating platform steel pipe spacing is 1.0m, in a crisscross manner and with brace
It reinforces, the springboard of paviour's walking is several to facilitate construction personnel's operation above operating platform.
6.3, flushing cinder giant is hoisted to inside eddy flow well shaft, 4 construction personnel's subregions is arranged to carry out flushing cinder work
Industry, control cabinet are placed in surrounding in whirling well well, convenient working personnel operation.
6.4, operating personnel washes away the soil body in whirling well well by flushing cinder giant, makes the soil body with slurry form by mud
Stock pump out well is outer to sedimentation basin, and during flushing cinder, upper layer soil body water content is less slowly uniformly to be washed away, and must not generate big
Block soil prevents obstruction slush pump.And when washing away to lower layer's soil body, since moisture content increases in soil, washes away rear soil property and be easier to
Lax, construction speed is accelerated.In flushing cinder giant scour process, preferably washed away outward by center at sector construction, mud
Slurry can be more uniform, and slush pump is blocked in the unsuitable monolith slump of full water and soil body.
6.5, during whirling well well-sinking, the borehole wall four need to be ensured by survey crew's time sight borehole wall inclination conditions
All difference of height≤10cm should increase erosion quantity to rectify a deviation to borehole wall higher position in time if run-off the straight is excessive.Due to flushing cinder
Method is continuously constructed, and is sunk very fast, and night can equally carry out, and is not present the relevant security risk of upper air installing, therefore daily eddy flow
Well theory settling amount is 1-1.3m.This method can not have to consider the adverse effects such as shaft bottom infiltration, but still need to control underground bearing water,
Artesian water water level is set to be advisable lower than borehole wall 0.5m.
6.6, mud is evacuated to outside sedimentation basin, and after from reprecipitation, impurity less clear water in top is back to clear water reserviors,
The reusable carry out flushing cinder of clear water, has greatly saved water resource.Dregs in sedimentation basin, made to whirling well wellbore section,
Sinking gap carries out simple preliminary sunning and is transported to outside construction site before Yu Xuanliu well shaft next stage, flushing cinder sink.
6.7, when whirling well well-sinking is to close to bottom absolute altitude, 100mm is reserved, stops sedimentation, and build below bottom beam
Piled bricks can carry out direct back cover when continuous sedimentation is no more than 100mm in 8h.
7, back cover.
Three, pay attention to late maintaining and Lost circulation problems
The utility model has the advantages and positive effects of:
1, the utility model structure is simple, easy to operate, during open caisson is unearthed, eliminates traditional dry type and goes out the earthwork
Formula in the construction process, is not used large excavator tool, construction cost and energy consumption is greatly saved using wet work,
And fugitive dust and noise pollution are effectively prevented, capital investment is few.The simple mode for relying on hand digging, time saving province are improved simultaneously
Power, short construction period, construction efficiency are high.
2, the utility model is in borehole wall manufacturing process, pre-buried I-steel or C-type steel, convenient to be unearthed in subsequent open caisson
Operating platform is set up in journey, to guarantee the safety of subsequent unearthed operating platform.
3, the utility model uses High-power Mud Pump, and mud is evacuated to the settling apparatus outside well, reduces security risk,
And water after precipitation is reusable, energy conservation and environmental protection.
4, the utility model can use hydraulic giant quantity according to open caisson diameter and on-site actual situations, reasonable distribution, right
Title washes away sinking.Flushing cinder process is to work continuously, the shaft bottom mud lubrication after flushing cinder, and open caisson is more efficient.In the construction process,
There are professional and professional equipment emphasis to carry out the detection of absolute altitude and verticality, inclination of open caisson can be effectively prevent.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
