TH430A - Horizontal tunnel boring equipment - Google Patents

Abstract

Tunnel boring equipment with a cylindrical shield is suitable for weak or unstable land areas to be assured that It can resist the pressure of the tunnel surface even in the presence of high water content. And it is also possible to transport the mud to the outside thanks to the fixed head of the mixing chamber. Partition wall of the septum The criss-cross shaped wing rotates around an axis at the front end at The way the room opened It is like embedded in a partition wall and on the outside surface with blades attached. The back surface has several blades. Stuck to mash The paddle extends further to the rear, in addition, it consists of a ring that will hold the forearm of the criss-cross flap. Even the area The edge of the mixing room To be able to mash all the mud in the room Knead as best By adding mud To get Cole Viscosity suitable for conveying And will transfer the bag-shaped screw conveyor Tell me where to go from the way out of the 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 outermost 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 method Two cylindrical conveying 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 device 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 sixth, where the screw conveyor both rotate in the same direction. 8.Equipment, according to any one referred to in Articles 4 to 6, states that both screw conveyor are rotated against each other (8 clauses, drawing-picture).
