Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a propulsion method in which a shield tunneling machine is used to dig a horizontal hole and a propulsion pipe is constructed inside the horizontal hole. This is related to the soil removal equipment that is used in this field.

Conventional technology Conventionally, as shown in FIG. 9, earth and sand generated by excavation by a shield excavator 31 are raised by a belt conveyor 32, and then removed by a trolley 3, as shown in FIG.
A belt conveyor/trolley method is used in which soil is loaded into a tank 3, and after running a trolley 33 in a hump pipe 34, it is discharged by a packet 36 through a vertical shaft 35.As shown in FIG. This was done using a pelt conveyor arrangement system, which sequentially conveys the earth and sand, and a piping system using a piston pump.

Problems to be Solved by the Invention Among the above-mentioned conventional methods, in the belt conveyor/trolley method and the belt conveyor arrangement method, earth and sand during conveyance spills into the fume pipe 34. In the belt conveyor arrangement method, one of the hume pipes 34 to be added is
One power source is required for each book, and many power sources are required. Furthermore, the pipe pressure feeding method cannot be installed in a small-diameter propulsion method, and the soil needs to be improved in order to be pumped.

An object of the present invention is to provide an earth removal device using a propulsion method that can transport even coarse gravel in a sealed state without soil improvement, and that can reduce the number of driving sources.

Means for Solving the Problems In order to solve the above-mentioned problems, the earth removal device of the propulsion method of the present invention is an earth removal device of the propulsion method in which a shield tunneling machine is used to dig a horizontal hole and a propulsion pipe is constructed in the horizontal hole. A soil device,
A non-driving earth removal unit is composed of a casing that is movable within the propulsion pipe and a ribbon screw disposed within the casing, and a casing, a ribbon screw, and a discharging unit provided on the casing side in conjunction with the ribbon screw. The drive device constitutes a drive soil removal unit.

By sequentially arranging these earth removal units of the same type or different types,
It is configured to allow connection between casings and ribbon screws.

According to the configuration of the present invention, as the shield excavator moves forward, one of the two earth removal units is arranged, and the opposing casings and ribbon screws are connected, thereby allowing the shield excavator to move from the shaft to the shaft. The earth and sand can be transported in a sealed casing by operating the drive device of the drive earth removal unit connected only at appropriate locations and rotating the ribbon screw connector. It is possible.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 6.

Reference numeral 1 denotes a shield excavator which moves forward while digging a horizontal hole 3 from a vertical shaft, and a humuum pipe 4 is sequentially constructed inside this horizontal hole 3.

Reference numeral 5 denotes a non-driving earth removal unit, which is composed of a cylindrical casing 7 that is movable within the hump pipe 4 via wheels 6, and a ribbon screw 8 disposed inside the casing 7. A connecting flange 9 is provided in a flange-like manner, and a connecting plate 10 is provided in a continuous manner forward from both sides at one end, for example, the front end of the ribbon screw 8. Reference numeral 11 denotes a drive earth removal unit, which, like the non-drive earth removal unit 5 described above, has wheels 6. It consists of a casing 7, a ribbon screw 8, a flange 9, and a connecting plate 10, and a driving device e112 is provided on the casing 7 side in conjunction with the ribbon screw 8 at the intermediate portion in the longitudinal direction. This drive device 5112 includes a cylindrical case body 13 that connects and integrates the intermediate ends of the divided casing 7, and a rotatable structure that is provided on the inner peripheral surface of the cylindrical case body 13 via a sealing material 14 or the like. A supported annular body 15, an annular passive gear 16 fixed on the outer peripheral surface of the annular body 15, and a case integrated at appropriate positions on the outer circumference of the cylindrical case body 13 and communicated with each other via a communication portion 17. 18, a drive motor (guard motor) 19 attached to the outside of this case 18, and this drive motor 1
9, and a drive gear 21 which is attached to the output shaft 20 of the ribbon screw 8 and meshes with the driven gear 16 through the communication part 17. Concatenated. Note that one of the non-driving earth removal units 5 has an earth removal port 23 of the shield excavator 1.
A hopper 24 that can freely face is provided.

Next, the operation of the above embodiment will be explained.

The earth and sand generated by the excavation of the shield excavator 1 is discharged through the earth discharge port 23.
from there to the hopper 24. At this time, the drive motor 19
is in operation, and the rotation of the output shaft 20 is caused by the drive gear 21
, is transmitted to the ribbon screw 8 via the passive gear 16, the ring body 15, and the connecting member 22, and causes the ribbon screw 8 to rotate within the casing 7. As a result, the earth and sand in the hopper 24 is continuously transported inside the casing 7 toward the shaft side by the ribbon screw 8. At this time, since the ribbon screw 8 does not have any shafts, even coarse gravel can be transported without becoming jammed if it gets caught. As the shield excavator 1 moves forward, the non-driven earth removal unit 5 or the drive earth removal unit 11 is connected. That is, the casings 7 can be connected by bringing the flanges 9 into relative contact with each other and integrating the flanges 9 with a connecting tool 25 such as a bolt, nut, or pin.

Further, the ribbon screws 8 can be connected by fitting the rear ends of the front ribbon screws 8 between the connecting plates 10 and integrating them with the connectors 26.

FIGS. 7 and 8 show another embodiment. That is, a casing 27 with a U-shaped cross section is used, and a lid 28 is provided that can open and close the top opening. This lid body 28 is made of a mesh or an iron plate, and can be attached to and detached from the casing 27 via a connector 29. By removing the lid 28, internal maintenance and connection between the ribbon screws 8 can be easily performed, and when using a net, the conveyance status during operation can be grasped. Note that an inner cylinder guide 30 is provided on the lower surface side of the lid body 28 at the location of the flange 9.

Effects of the Invention According to the present invention having the above configuration, the earth and sand can be continuously conveyed by the ribbon screw within the sealed casing, and will not spill into the propulsion pipe. In addition, since it is transported by a ribbon screw, compared to a normal screw with each shaft, even coarse gravel can be transported without becoming clogged if it gets caught. can be made unnecessary. Furthermore, the driving earth removal unit having a drive device need only be installed at the optimum location, and the power source can be reduced, making it possible to carry out the earth removal work economically.
