Saw grooving machine

Abstract

The invention discloses an under ground continuous saw notching machine which includes the horizontal frame, the leader with vertical two sides, the diving electric engine in the frame center, the diving sandstone pump. The special part is: the blower of the diving electric machine is set with the brace which is set with the cutter arbor A and B on two sides, the brace is connected with the connecting rod A which is connected with rocker A which the end is connected with the cutter arbor A; the upper of the rocker A is connected to the connecting B which is connected with the rocker B which the end is hinged with cutter arbor B. it can be used in building the dyke cut-seep wall in river, reservoir and the lake and the underground continuous wall of building, port, dock, subway and the underground station.

Description

(1) Technical field [0001] The invention relates to a slotting machine, in particular to an underground continuous wall saw type slotting machine. (2) Background technology [0002] At present, the trough forming machines used in the construction of underground diaphragm walls can be roughly divided into three types according to their trough digging mechanism: bucket type, impact type and rotary type. The bucket type slotting machine cuts the soil with its bucket teeth, stores the cut soil residue in the bucket body, transports it out of the ground from the trench, opens the bucket to pour out the soil residue, and then returns to the excavation position, so reciprocating work, power consumption Large size and high cost; the impact slotting machine uses the drill bit to impact and break the foundation soil, and the soil residue is carried out of the slot by means of mud circulation. The slotting speed of this slotting method is very slow; the rotary slotting machine is drive...

AI Technical Summary

Problems solved by technology

The bucket type slotting machine cuts the soil with its bucket teeth, stores the cut soil residue in the bucket body, transports it out of the ground from the trench, opens the bucket to pour out the soil residue, and then returns to the digging position, so reciprocating work, power consumption Large and expensive; the impact slotting machine uses the drill bit to impact and break the foundation soil, and the soil slag is carried out of the slot by means of mud circulation. The slotting speed of this slotting method is very slow; the rotary slotting machine is driven by a submersible motor Multi-head drill, rotary drilling into the slot, the soil residue is discharged out of the slot with the circulating mud, this way the equipment maintenance cost is high

From the above analysis, it can be seen that the efficiency of the slotting machine for the existing underground diaphragm wall is low, and the cost of construction equipment is high

Common slot joints are complex in form and poor in effect
