Description
Technical field
The utility model relates to a kind of water king-pile construction equipment, particularly a kind of pump circulation construction equipment.
Background technology
In the water during pile driving construction, because a variety of causes, occur the growth of long casing bottom leaky or bedrock fracture sometimes and stratum seepage (formal name used at school is called leakage) occurs.When leakage occurring, the improper decline of mud face in the well, well head can't return slurry, and the direct circulation construction can't continue.
Seepage treatment in the pile foundation pore forming process is got up very complicated, and cost is high.At first to carry out leak stopping, need a large amount of mud materialses; Next is that leak stopping will spend the long engineering time; The 3rd is because the viscosity of loss circulation material is big, has increased the difficulty of follow-up construction greatly.
Because during pile driving construction, platform is higher in the water, the inside and outside head difference of casing is big, handles difficulty more when leakage rain occurring.
Summary of the invention
The purpose of the utility model is the defective that overcomes prior art, and water king-pile leakage problems provides a kind of pump circulation construction equipment.
Technical scheme of the present invention comprises:
A kind of pump circulation construction equipment comprises:

Wherein, this mud replenishes pipeline and extends to drill bit.Mud ditch provides from this mud and extracts the mud path of pipeline to this mud pit, and vibrosieve is arranged on this mud path.This gravel pump is located at balance liquid level below, and preferably, this gravel pump is located at one meter, balance liquid level below.
Technical scheme of the present invention also comprises:
A kind of water king-pile construction system comprises wellhole and mud pit, in this wellhole, is provided with the construction drill bit, and this system also comprises:
The mud supplemental component comprises that the slush pump that is located in this mud pit replenishes pipeline with the mud that is connected with this slush pump and extend to this wellhole from this slush pump;
Mud extracts assembly, comprises the gravel pump that is located in this wellhole and is connected with this gravel pump, the mud extraction pipeline of slurry conveyed.
Wherein, this mud replenishes pipeline and extends to drill bit.Mud ditch provides from this mud and extracts the mud path of pipeline to this mud pit, and vibrosieve is arranged on this mud path.This gravel pump is located at balance liquid level below, and preferably, this gravel pump is located at one meter, balance liquid level below.
Positive progressive effect of the present invention is: utilize simple mechanism to solve the leakage problem; Follow-up construction can be by normal direct circulation job practices operation; Can not carry out leak stopping for the leakage in the scope of application and handle, directly construct, practice thrift engineering time and cost by former construction technology.
Description of drawings
Fig. 1 is the utility model schematic representation of apparatus.
The specific embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is elaborated.
The pile foundation direct circulation is constructed must guarantee following condition: pile foundation breast wall is stable during the balance liquid level, the retaining wall when quality of mud fluid can guarantee construction is stable and return the slurry requirement and well head returns slurry.
Shown in preceding, when leakage occurring in the construction, the improper decline of mud face in the well, well head can't return slurry, and the direct circulation construction can't continue.After leakage appearred in the water king-pile, because outside head effect, liquid level dropped to and just no longer descends after the external water plane is consistent in the well.
The principle of the utility model is to adopt the direct circulation of double pump mud, mainly is to utilize slush pump that the mud for preparing is passed the leakage section through conduit, is injected into the position of Hot work in progress, thereby satisfies the condition of direct circulation construction.
As shown in Figure 1, the device of the utility model comprises that mud supplemental component 100 and mud extract assembly 200.
This mud supplemental component 100 comprises the slush pump 110 that is located in the mud pit 20 and replenishes pipeline 120 from the mud that this slush pump 110 extends to drill bit 30 wellhole 10; The slurry transportation that the additional pipeline 120 of this mud is got these slush pump 110 pumps arrives this drill bit 30, misses the mud that goes with additional well.
This mud extracts that assembly 200 comprises the gravel pump 210 that is located in the wellhole 10 and is connected with this gravel pump 210, the mud extraction pipeline 220 of slurry conveyed.This mud extracts pipeline 220 sandstone is drawn on the mud ditch 40, utilizes vibrosieve 50 to filter out rock ballast, and the slurry transportation after mud ditch 40 will filter is in this mud pit 30.
Wherein, this gravel pump 210 is located near balance liquid level (below), returns slurry so that form well head.
As spillage takes place, the binary cycle system that adopts slush pump 110 and gravel pump 210 to form carries out anti-slag construction.By slush pump 110 mud in the mud pit 20 is evacuated in the wellhole 10, the mouth of pipe that mud replenishes pipeline 120 is fixed on the drill bit 30, bring to the hole by drill bit 30 at the bottom of.
By little hoist engine gravel pump 210 is transferred following 1 meter of water level (balance liquid level) to the wellhole.Opening gravel pump 210 is evacuated to mud in the hole in the mud pit; Dsah-pot can be installed at gravel pump mouth of pipe place; After buffering, filter on slurry flows to vibrosieve 50, the mud after the filtration flow in the mud pit 20 through mud ditch 40, so forms the circulating system of mud.
The utility model is applicable to that leakage is not more than 30m
3The geology feelings portion condition of/h, pile foundation is good, the situation of no soft layer,
Although the utility model is described according to its preferred implementation, there are the change, displacement and the various substitute equivalents that fall in the utility model scope.Here the example that provides only is illustrative, rather than to the restriction of the utility model.
For the sake of simplicity, this manual has omitted the description to known technology.
