Abstract
The utility model relates to a double-pipe jet grouting drilling machine, which belongs to the field of the piling machinery. The double-pipe jet grouting drilling machine is characterized by comprising a box body, wherein a double-pipe grouting water faucet is arranged inside the box body, the double-pipe grouting water faucet is connected with a slurry conveying pipe and an air conveying pipe, the slurry conveying pipe and the air conveying pipe are arranged inside a drill pole, the tail end of the drill pole is provided with a drill bit, and the upper end of the drill pole is connected with a power device. Through the closely-matched power mechanisms, the drill pole drives the drill bit to rotate rapidly, the slurry conveying pipe and the air conveying pipe rotates at a high speed along the drill pole, and the slurry and the high-pressure air are simultaneously jetted, so that the cutting effect is better, more efficiency for improving the soil quality can be realized, and the reinforcement effect can be greatly improved.
Description
Technical field
The utility model relates to a kind of two-tube rotary jet grouting rig, belongs to the piling machinery field.
Background technology
In foundation reinforcement method, a kind of time-honored static pressure chemistry or cement injection method are arranged, it is with hardener of different nature (chemicals or cement), is injected in the ground with pressure, in order to improve property of soil.This method mainly is applicable to sandy soil, also can be applicable to cohesive soil.But under many circumstances, because the relation of soil layer and soil nature, its consolidation effect Chang Buwei people control, and especially in the layered ground and interlayer ground how of deposition, injectant often flows along aspect; In fine grain soil, injectant is difficult to be penetrated in the hole of particle.Therefore, the unconspicuous situation of consolidation effect often appears.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of two-tube rotary jet grouting rig is provided, by cutting and the mixing of high pressure jet stream, hardener and the soil body is mixed, reach the purpose of improvement soil property.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of two-tube rotary jet grouting rig, it is characterized in that, comprise casing, be provided with two-tube slip casting water halter in the casing, two-tube slip casting water halter connects to send starches pipe and air pipe, send slurry pipe and air pipe to be arranged in the drilling rod, the end of drilling rod arranges drill bit, the upper end connecting power device of drilling rod.
Described power set comprise motor, and motor connects driven wheel by rotary reducer, and driven wheel connects rotary flange, and rotary flange is by six square joint jointed rods.Motor provides enough rotary powers in the power set, and rotary reducer and the driven wheel that is mated, rotary flange, six square joints have been finished the effect of protection rig and effective sealing jointly.
The beneficial effect that the utility model has is: make drilling rod drive the drill bit fast rotational by cooperating close actuating unit, send slurry pipe and air pipe with the drilling rod High Rotation Speed, mud and pressure-air are sprayed simultaneously, cutting effect is better, more effective during the improvement soil property, greatly improve consolidation effect.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1, casing; 2, two-tube slip casting water halter; 3, send the slurry pipe; 4, drilling rod; 5, motor; 6, rotary reducer; 7, driven wheel; 8, rotary flange; 9, six square joints; 10, drill bit; 11, air pipe.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Two-tube rotary jet grouting rig as shown in Figure 1, comprise casing 1, be provided with two-tube slip casting water halter 2 in the casing 1, two-tube slip casting water halter 2 connects to send starches pipe 3 and air pipe 11, send slurry pipe 3 and air pipe 11 to be arranged in the drilling rod 4, the end of drilling rod 4 arranges drill bit 10, the upper end connecting power device of drilling rod 4.Power set comprise motor 5, and motor 5 connects driven wheel 7 by rotary reducer 6, and driven wheel 7 connects rotary flange 8, and rotary flange 8 is by six square joints, 9 jointed rods 4.
Operating principle:
Two-tube slip casting water halter 2 is fixed in the casing 1, and main effect is to prevent that high-pressure slurry from exposing outside the rig, plays sealing function, and high-pressure slurry and pressure-air be transported to send in slurry pipe 3 and the air pipe 11.Motor 5 slows down through rotary reducer 6 and makes driven wheel 7 rotations, driven wheel 7 drives to be installed in and drives the macro-axis rotation, and then drive rotary flange 8 rotations that are installed in the macro-axis bottom, and then driving connected six square joints 9, last six square joints 9 drive drilling rods 4 and drill bit 10 rotations.Through this a series of transmission, drill bit 10 is in rotation, and high-pressure slurry is transported to drill bit through send slurry pipe 3 and the air pipe 11 that connect together of every joint, at last by shower nozzle to around spray, the cutting surrounding soil reaches the purpose of reinforcing boring.
Claims (2)
1. a two-tube rotary jet grouting rig is characterized in that, comprises casing, be provided with two-tube slip casting water halter in the casing, two-tube slip casting water halter connects to send starches pipe and air pipe, send slurry pipe and air pipe to be arranged in the drilling rod, the end of drilling rod arranges drill bit, the upper end connecting power device of drilling rod.
2. two-tube rotary jet grouting rig according to claim 1 is characterized in that, described power set comprise motor, and motor connects driven wheel by rotary reducer, and driven wheel connects rotary flange, and rotary flange is by six square joint jointed rods.
