Description
Technical field the present invention relates to a kind of in engineerings such as civil construction drilling stratum, the multiple-drill press of constructing the uniform thickness diaphragm wall and job practices thereof.
Background technology is present, be one of known technology of people, be a kind of technology of using multiple-drill press to construct colonnade formula diaphragm wall: it is the multiple-drill press by special use, drive one group of drilling rod, the segmentation formation drilling promotes go back to ground to certain depth, in the process of one group of rod boring or lifting, can inject cement paste to soil from the drill bit end, with stirred by the loose mixing with soil of bit drills, be built into one section cement-soil body of wall; And then carry out the construction of next section cement-soil body of wall, and make the two neighboring sections body of wall that certain coincidence overlap joint be arranged each other; Repeat above-mentioned construction, can be built into a underground water earth body of wall; Before the cement-soil body of wall solidifies, can insert shaped steel and wait the intensity that improves body of wall, after the cement-soil body of wall solidifies, just caused the diaphragm wall of a colonnade formula.
The major defect that the technology of using above-mentioned multiple-drill press to construct colonnade formula diaphragm wall exists is: the body of wall that causes is non-uniform thickness, is cucurbit string shape (referring to Fig. 6), variable thickness, and intensity is inhomogeneous; When particularly using as impervious wall, percolating water phenomenon takes place in the sharp corner of body of wall easily; And arrangement and the quantity of inserting shaped steel also are restricted.
For overcoming the shortcoming of above-mentioned technology, Japan Patent (spy opens flat 6-235219) discloses a kind of multiple-drill press, be characterized in drilling rod and with the axis of rotation of its axis normal on be provided with a pair of intermeshing helical gear, on axis of rotation, also be provided with a cutting cutterhead; When drilling rod rotated, the power by helical gear transmission drilling rod drove the bite disc spins by axis of rotation, and the wedge angle part that can scabble the continuous body of wall of colonnade formula makes the thickness of wall body unanimity.But this technology still exists following deficiency and shortcoming:
1, adopts helical gear drive, with roller bearings, also need to need lubricated and sealing etc., complex structure, processing and manufacturing cost height.
2, when drilling rod during in underground drilling, seal is easy to wear, and the sand contamination of muddy water soil causes transmission device to damage after going into the gear drive position easily, influences normal construction, and the maintenance and repair workload is big.
3, since the helical gear drive complex structure to occupy the space big, when drilling rod during in underground drilling, it is moving that this position hinders native sand flow, the resistance when increasing drilling reduces operating efficiency.
Summary of the invention the object of the present invention is to provide a kind of multiple-drill press and the job practices thereof that can construct the uniform thickness diaphragm wall; This multiple-drill press such as constructs at simple in structure, the low cost of manufacture, easy to maintenance of topping machanism of thick wall body; Its construction technology is simple, construction quality good, efficient is high.
The objective of the invention is to realize by following technical proposals:
A kind of multiple-drill press mainly comprises: support machine, drill power head and drilling tool.
Above-mentioned support machine is mainly by the base of traveling on the ground, and the column, elevator unit, operating room and the haulage cable that are arranged on the base constitute.
Above-mentioned drill power head is mainly by frame movably, is arranged on the frame and the drive unit that contains prime mover, reductor and plural force-output shaft constitutes; Drill power head hangs on the column of support machine by haulage cable, and can move up and down.
Above-mentioned drilling tool mainly is made of one group of drilling rod, shaft coupling, shaft coupling seat and guiding device; Described drilling rod is made up of hollow extension bar, hollow helical stir bar and the drill bit that has a jet, and drilling rod links by the force-output shaft of shaft coupling and drill power head.
It is characterized in that: also be provided with the rolling topping machanism of plural number on one group of drilling rod of described drilling tool, the rolling topping machanism is by the axle that is fixed on bearing on the shaft coupling seat, is supported by bearing and places the cutting roller on the axle to constitute rotationally; The cutting roller is provided with most cutter tips.
Use above-mentioned multiple-drill press to construct uniform thickness construction of continuous concrete wall method, have following steps:
The multiple-drill press traveling is to construction location, drill power head drives the drilling rod rotation of drilling tool, and downward drilling stratum, the rolling topping machanism also moves down thereupon, the wedge angle of the body of wall remnants of cutting roller after with the drill bit drilling partly scabbles, after reaching desired depth, drill power head and drilling tool lifting go back to ground; Above-mentioned creep into lifting process in, to soil, inject cement paste by hollow drill from the drill bit end, after being stirred, be built into one section cement-soil body of wall by the loose mixing with soil of bit drills; The construction of next section cement-soil body of wall is carried out in the multiple-drill press shift position, and makes the two neighboring sections body of wall that certain coincidence overlap joint be arranged each other; Repeat above step, can be built into the underground water earth body of wall of a uniform thickness, before the cement-soil body of wall solidifies, can insert shaped steel and wait the intensity that improves body of wall, after the cement-soil body of wall solidifies, just caused the diaphragm wall (referring to Fig. 7) of a uniform thickness.
The rolling cutting of rolling topping machanism is to realize with process as follows: when the rolling topping machanism moves down with drilling rod, the remaining wedge angle part of body of wall produces a counter-force F to it, owing between cutting roller center O and the counter-force F eccentric distance e is arranged, thereby the cutting roller has been constituted a rotating torque T=F * e, the rolling topping machanism move down and the effect of rotating torque T under the rotation of cutting roller, realize cutting to the remaining wedge angle part of body of wall.
Multiple-drill press of the present invention and job practices thereof have following good effect and advantage:
1, according to the present invention, construct that uniform thickness construction of continuous concrete wall technology is simple, thickness of wall body equates, intensity is even, reliable in quality, barrier performance is good, inserts the quantity of shaped steel and arrange not restricted.
2, according to the present invention, the rolling cutting principle of rolling topping machanism of thick wall body such as constructing is reasonable, simple in structure, the processing and manufacturing cost is low, easy to maintenance.
3, according to the present invention, rolling topping machanism volume simple in structure is little, it is few to occupy the space, and when drilling rod during in underground drilling, the resistance that this position produces is little, and native sand flow is moving smooth and easy, the efficiency of construction height.
