A kind of structure design and novel construction process of spiral push-bench are proposed in patent, pass through the work of sludge pipe and helix tube
With mud is discharged backward during push pipe, reduces push pipe resistance, and the special artificial row of setting in received well before saving
Clay figurine person saves cost.
But this construction technology cuts soil layer, jack-in process resistance using fixed cutter tip by static pressure top power
Power is big, encounters the more difficult jacking of hard soil layer, influences construction speed and quality.
Invention content
In view of this, the present invention is directed to propose a kind of push-bench with rotary cutting head, passes through the cutter of rotation
Head chopping soil layer can be suitable for the construction of various complex random systems, reduce labor intensity, improve construction to reduce push pipe resistance
The advantages that efficiency, move speed is fast.
In order to achieve the above objectives, the technical proposal of the invention is realized in this way：
A kind of push-bench with rotary cutting head, including push pipe nose assembly, push pipe head front end are equipped with rotary cutting
Head is cut, rear end is equipped with sludge pipe.
The rotary cutting head is fixed on the rotary base ring of push pipe nose assembly front end, and the rotary base ring contains internal tooth
Circle, is connected by two carrier gears with the driving gear of push-bench nose assembly main shaft.
The sludge pipe is internally provided with helix tube, and the helix tube front end connects with the driving gear inside push pipe nose assembly
It connects.
The rotary cutting head is equipped with cutting tip.
Preferably, spoil disposal channel is equipped in the push pipe nose assembly.
Preferably, the helix tube is made of shaft and helical blade set, and the both ends of the shaft are respectively equipped with connection and use
The first pin hole, the helical blade set is arranged on shaft, including diameter is consistent and several spirals equidistantly to arrange
Blade.
Preferably, the both ends of the helix tube are equipped with the jointing that is oriented to and can transmit torque.
Further, the jointing is respectively equipped with the second pin hole corresponding with the first pin hole, and section is respectively
External contact zone and inscribed polygon, two end connector of shaft run through the first pin hole and the second pin hole with front and back helix tube by pin
It is fixedly connected.
Further, the port cross-sectional of the jointing is external contact zone, and the port cross-sectional of shaft is inscribed polygon
Shape.
Compared with the existing technology, the present invention has the advantage that：
1, by the cutting machine head of rotational structure, soil layer is shredded, the resistance of push pipe is reduced, various complex random systems can be suitable for
The advantages that construction reduces labor intensity, improves construction efficiency, and move speed is fast.
2, the setting of helix tube and sludge pipe, while mud is discharged from rear well, the process for having saved one of sludge pipe makes engineering
Save time and cost of labor.
