Extraction tube, under the effect of suck-back water and suck-back air adapter, can force to extract out by the waste mud of underground, thus solve tradition
Deficiency present in the gas lift spoil disposal method of Soil-cement pile work method.Although the drilling rod of current comprehensive high-pressure injection engineering method can be by
The waste mud of underground is forced to extract out, it is to avoid foundation pressure increases, and affects the ejection efficiency of high pressure nozzle, but it cannot base area
The actual pressure of basilar part controls the waste mud of underground forces extracted amount, it is difficult to basilar part over the ground during practice of construction
Actual pressure carries out suitable regulation.
Utility model content
The purpose of this utility model is to overcome gram the deficiencies in the prior art, it is provided that one can be executed actual
During work, the actual pressure of base area basilar part controls the waste mud of underground and forces extracted amount, with this adjustably basilar part
Actual pressure, it is to avoid foundation pressure increases, and affects the topping machanism of the comprehensive high-pressure injection engineering method of ejection efficiency.
The technical solution of the utility model is:
The topping machanism of a kind of comprehensive high-pressure injection engineering method includes drilling rod, be arranged in drilling rod spoil disposal pipeline, setting

Being provided with the spoil disposal valve of aperture area for controlling mud discharging mouth, described mud discharging mouth and pressure transducer are near drilling rod lower end.
Ground basilar part monitored in real time by the topping machanism of the comprehensive high-pressure injection engineering method of this programme by pressure transducer
Actual pressure, and the actual pressure data recorded according to pressure transducer adjust the size of spoil disposal valve, control underground
Waste mud forces extracted amount, with the actual pressure of this adjustably basilar part, reduces pressure in ground, is allowed to normal, it is ensured that high pressure spray
Penetrate efficiency.
As preferably, valve plate that spoil disposal valve includes the aperture area for controlling mud discharging mouth and the valve being arranged in drilling rod
Plate drives actuator.
As preferably, the end of valve plate is provided with cylinder, and described cylinder is rotatably provided on valve plate by axostylus axostyle, described axle
Bar and the axis perpendicular of drilling rod.
During underground waste mud is forced to extract out, owing to the end of valve plate is provided with cylinder, underground waste mud is by row
Cylinder can be driven during mud mouth to rotate, and the cylinder rotated can stir the coagula being gathered in mud discharging mouth, is allowed to loose
Open or leave mud discharging mouth, thus effectively reduce the situation that mud discharging mouth is blocked.
As preferably, cylinder surface is provided with some grooves.Owing to cylinder surface is provided with some grooves, this not only contributes to carry
High cylinder stirs dynamics and the efficiency of the coagula being gathered in mud discharging mouth, and is conducive to improving the strength that cylinder rotates, thus
The most effectively reduce the situation that mud discharging mouth is blocked.
As preferably, cylinder is positioned at mud discharging mouth.This programme structure can reduce the impact that drilling rod is worked by cylinder as far as possible.
As preferably, the lateral surface of drilling rod is provided with pressure transducer installing hole, and described pressure transducer is positioned at pressure and passes
In sensor installing hole.
As preferably, mud discharging mouth is rectangular.
As preferably, the axis coaxle of spoil disposal pipeline and drilling rod.
As preferably, pressure transducer is positioned at the lower section of mud discharging mouth.
The beneficial effects of the utility model are: can control by the actual pressure of base area basilar part during practice of construction
The waste mud of underground processed forces extracted amount, with the actual pressure of this adjustably basilar part, it is to avoid foundation pressure increases, and affects spray
Penetrate efficiency.
