Description

Automatic grouting soil-pressure mud-water balance push bench

Technical Field

The utility model relates to a push bench, concretely relates to but automatic slip casting soil presses balanced push bench of muddy water.

Background

With the development of society and the rapid increase of population density, the development of urban underground spaces is accelerated by people, and the main forms of development and utilization of urban underground spaces, such as rail traffic, urban pipe corridors, underground electric power pipe networks and the like, need to pass through buildings (structures) dense areas, so that the trend and the necessity of adopting a subsurface excavation construction method which has relatively small influence on the ground and the surrounding environment are called, and the pipe jacking method has the advantages of no traffic obstruction, no environment damage, low noise and low pollution, has small influence on the surrounding environment, and can be used when the pipe jacking is used.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a can let the mud carry out the slip casting and let the mud easily transmit out the balanced pipe push bench of mud pressure soil of can automatic slip casting of pipe push bench simultaneously.

The utility model discloses a following technical scheme realizes: but automatic slip casting soil pressure muddy water balance push bench is provided with frame and auger delivery part the frame on be provided with the motor, be provided with the blade disc on the motor, the blade disc rotate the action under the drive of motor the blade disc on be provided with the multiunit tool bit, the frame on be provided with the slip casting hole, the slip casting hole rely on the conveyer pipe to carry slip casting liquid to push bench.

The grouting hole on be provided with electric ball valve, electric ball valve rely on the conveyer pipe of carrying mud and the reserve tank of reserve mud to switch on each other, rely on mutually supporting the slip casting action in control grouting hole of conveyer pipe and electric ball valve.

The electric ball valves are distributed on the rack, and the electric ball valves are communicated with the grouting holes to realize grouting operation through the grouting holes.

The electric ball valve is connected with the PLC through a communication pipeline, the electric ball valve is controlled by the PLC, and the electric ball valve is controlled to be opened and closed intermittently under the control of the PLC.

Compared with the prior art, the utility model discloses when using, be provided with the slip casting hole on the push bench, the slip casting hole relies on the conveyer pipe to push bench transport slip casting liquid, relies on slip casting liquid to reduce the friction between push bench and the soil body, reduces the resistance between push bench and the soil body, lets the push bench operation convenience more of push bench for the push bench is at the operation in-process side friction reduction.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic view of the cutter head of the present invention.

Fig. 3 is a partial enlarged view of the present invention.

In the figure: the device comprises a frame 1, a motor 2, a cutter head 3, an electric ball valve 4, a spiral conveying pipe 11, a grouting hole 12, a conveying trolley 13, a movable roller 14 and a movable guide rail 15.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

But automatic slip casting soil pressure muddy water balance push bench is provided with frame 1 and auger delivery part the frame on be provided with motor 2, be provided with blade disc 3 on the motor, blade disc 3 carry out the rotation action under the drive of motor 2 blade disc 3 on be provided with the multiunit tool bit, the frame on be provided with grouting hole 12, grouting hole 12 rely on the conveyer pipe to carry the slip casting liquid to push bench.

The spiral conveying part adopts the spiral to send conveyer pipe 11, be provided with helical blade in the spiral sends conveyer pipe 11, make helical blade move under the drive of motor, can carry the pipe push bench outside with the rubble and the mud mixture that cut off under the operation that the conveyer pipe was sent to the spiral, the further operation of the pipe push bench of being convenient for, send conveyer pipe 11's lower part at the spiral and be provided with defeated material dolly 13, be provided with travelling wheel 14 and movable guide 15 under defeated material dolly 13, the grit is carried to defeated material dolly 13 of being convenient for.

When carrying out the slip casting operation, put into the reserve tank with mud according to the proportion and carry out the operation, mud generally adopts bentonite thixotropic mud, then be provided with the mud pump in the reserve tank, when needs carry out the slip casting, PLC control starts electric ball valve, electric ball valve 4 is opened, the mud pump carries out the operation simultaneously, carry mud from the conveyer pipe to grouting hole 12, grouting hole 12 overflows mud, the mud that overflows makes to form moist effect between pipe jacking machine and the soil body, can reduce the side friction resistance between pipe jacking machine and the soil body, be provided with electric ball valve 4 on grouting hole 12, electric ball valve 4 relies on the conveyer pipe of carrying mud and the reserve tank of reserve mud to switch on each other, rely on the slip casting action of conveyer pipe and electric ball valve 4 mutually supporting control grouting hole.

Electric ball valve 4 distributes in the frame, and electric ball valve 4 and slip casting hole 12 switch on each other and realize carrying out the slip casting operation by the slip casting hole, and electric ball valve 4 connects through communication pipeline and PLC, relies on PLC to control electric ball valve, controls electric ball valve intermittent type under PLC's control and opens and close, PLC be programmable logic controller, can adopt the programmable logic controller that can control electric ball valve among the prior art, can let electric ball valve 4 intermittent type open and close under programmable logic controller control, realized the automatic supply that carries out mud, the effectual reduction of frictional resistance when letting the operation of push bench, push bench efficiency promotes in the push bench.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
