TH2583B - Horizontal tunnel boring equipment - Google Patents

Abstract

Cylindrical shielded tunneling equipment is suitable for use on soft or unstable soils to ensure that Will be able to withstand the pressure of the soil surface of the tunnel, even in the presence of high water content. and can also transport mud to the outside as well. The mixing chamber head can also be determined. Partition wall of the septum The wings have a criss-cross shape that rotates around an axis at the front end. The opening side of the room As if embedded in a septum and through the surface, the outer face had a blade attached to it. There are many paddles on the back surface. stuck to mix The paddle is extended at the stern. In addition, it consists of a ring to hold the forearm of the criss-crossed wing, on which the pavement surface is attached to the paddle to cover the mud. even the area The rim of the kneading chamber to be able to mix all the mud in the room mix best by adding a mud-forming substance to get Cole Viscosity suitable for conveying and will transfer the kraft-shaped screw conveyor Tell me where from the exit of the muddy mud at the bottom of the partition wall by open conveying

Claims (8)

1.Device for horizontal tunneling The tunneling system was used for the septum, where the land was drilled while the septum rotated itself. The septum matches the soil on the surface of the tunnel. To drill a tunnel The penetrating tunnel wall will be supported by reinforcing equipment that Said this contains a mixing room Whose edge is defined by the partition wall at In the front of the septum and the part that opens to the surface Wings that turn It rotates on the front of the mixing chamber and the front surface has a blade attached to the surface of the soil. To feed the sludge, there will be an open end to the mixing chamber to deliver the substance into the mixing chamber. Several paddle blades are also attached to the wing surface and on the peripheral ring on the outermost tip of the wing portion for mashing of the muddy agent with the cut soil. Enter the mixing room To get mud with just pressure To resist erosion of the surface of the tunnel as well as from the pressure of the groundwater. The part that will drive the blade will be attached to the part that is The wing rotates at the rear of the mixing chamber partition and the transport cylinder is connected to the mixing chamber with a mud transfer channel. Out back Inside the housing of the conveyor is a screw conveyor, which is the conveying method. 2. The equipment referred to in item 1 at the place where the paddle blade is attached, which is The anterior surface of the rotating ring in the area of the internal surface of the septum. 3. Equipment mentioned in item 1 or 2 with multiple pipes. At least one of the pipes must Was brought open at the end of the septum 4. Equipment as claimed in point 1, where it says it is a means The conveying is of two cylinders next to each other. Both of which This will work in harmony with each other. That is, it has to contain A pair of screw conveyor Which each were placed on top of each other 5. The equipment claimed in Article 4, where it is called the conveying method, is connected to the lower part of the partition designated as a mixing chamber. It is tilted diagonally to the back and upward of the septum. 6. Equipment as claimed in Article 4, where it is called the Method. Conveyor - along the axis of the septum from the center of the wall. To the back of the septum 7.A device according to any one of the four to 6, where the screw conveyor both rotate in the same direction. 8. Any equipment referred to in Articles 4 to 6 that states that both screw conveyors are rotated against each other (8 claims, drawing-picture).
