Description
SPECIFICATION
Improved apparatus for piercing tunnel through soft stratum Background of the invention This invention relates to an improved apparatuses- pecial Iy adapted for use i n piercing tunnel through soft stratum.
Conventionally, when required to pierce a tunnel through soft stratum, it is necessaryto use a lot of bracing membersforsupporting thetunnel. In addition, the conventional method cannot provide suf ficient securityforthe workers therein. Moreover, the advancing speed is undesirable, thereby increasing the manufacturing cost of the tunnel. Accordingly, an improved propelling device has been developed to eliminate the above-mentioned drawbacks. The propelling device is advanced forward by a number of jacks so as to pierce through the soft stratum to form a holewhich is then madefirm by coating a layer of material such as grout to the inside thereof.Hence, it is no long necessary to use a lot of bracing members to supportthetunnel. Furthermore,there is no disturbance between performing piercing and coating, thus expediting the progress oftunnel construction work. However, when such a propelling device is blocked by rocks, it is very difficult to remove them, resulting in delaying the progression of the construction work. Besides, the propelling device is not provided with means for preventing water from entering therein.
Therefore, it is an object ofthe present invention to provide an improved apparatus which may obviate and mitigate the above-mentioned drawbacks.
Summary ofthe invention
It is the primary object of the present invention to provide an improved apparatus which is especially adaptedforusein piercing tunnel through soft stratum.
It is another object of the present invention to provide an improved apparatus which may expedite the tunnel construction work.
It is still another object of the present invention to provide an improved apparatus which may reduce the manufacturing cost of tunnel construction work.
It is a further object of the present invention to provide an improved apparatus which is easy to operate.
It is still a further object of the present invention to provide an improved apparatus which is economicto produce.
Other objects and merits and a fuller understanding of the present invention will be obtained by those having ordinary skill in the artwhen the following detailed description of the best mode contemplated for practicing the invention has been read in conjunction with the accompanying drawings wherein like num eralsrefertolikeorsimilarpartsand inwhich: Briefdescription of the drawings::

Figure2 is an end elevational view of the prior art device;
Figure 3 is a sectional view of an apparatus according to a preferred embodiment of the present invention; Figure4is an end elevational view of Figure3; Figure5is a sectional view showing the head portion ofthe apparatus;
Figure 6is an end elevational view of Figure 5;
Figure 7shows the water-proof gate ofthe apparatus according to the present invention; and
Figure 8 is a fragmentary view showing the structure ofthe main body ofthe apparatus according to the present invention.
Before explaining the present invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also it isto be understood that the phraseology orterminology employed herein is for the purpose of description and not of limitation.
Referring nowtothedrawingsand in particularto
Figure 3 thereof, the apparatus 30 according to the present invention comprises a head portion 40 and a body portion 60. The head portion 40 is fixedly connected with the body portion 60 by suitable means such as screw fasteners, rivets and soon. The head portion 40 is provided at the rear witch a water-proof gate 50 on which may be mounted necessary devices such as excavators, drills, etc. The body portion 60 is composed of a plurality of cylindrical members 61, pneumatic cylinders 62, and grouting pipes 70 spaced apart along the circumference of the rearmost one of cylindrical members 61. Within the body portion 60 are mounted racks 80 adapted for use with rail trucks 81 (see Figure 4).
With reference to Figures Sand 6, there are shown a sectional view and a side view of the head portion 40 respectively. The head portion 40 is rigidly attached to the front of the body portion 60. The head portion 40 is provided in the front with a frame 41 having a plurality of lattices 42. As the head portion 40 is impeded by large rocks during advancing forward, it is only necessary to cut off a piece of the frame 41 by welding orthe like so asto removethe rock and then join back the piece to the frame 41.
Since the frame 41 has a plurality of lattices 42, the soil will not fall downwards in large quantity. (as shown in Figure 10). Hence, no collapse of soil will happen.
As shown in Figure 7, there is shown a perspective view of the water-proof gate 50. The water-proof gate 50 is disposed in the rear part of the head portion 40.
The water-proof gate 50 is a frame constituted by horizontal bars 52 and vertical bars 51, forming a plurality of lattices. Two sides of the gate 50 are provided with a door 53 through which the operator may go outto manage anything required. Further, there is a window 54 enabling the operatorto watch the circumstance in the front atthe time of advancing.
Turning to Figure 8, the body portion 60 ofthe apparatus 30 is pushed by pneumatic cylinders 62.
Each joint is constituted by a cylindrical member 61 and a number of pneumatic cylinders 62. Consequently, the cylindrical members 61 will be pushed for wards by by the pneumatic cylinders 62. The rearmost cylindrical member 61 is pushed by the rearmost pneumatic cylinders 62 which is supported on the lining. Each cylindrical member 61 is provided with two annular flanges 64 for enhancing the structurethereof so asto be able to bearagainstthe pressure exerted by the soil located on the circumference.
Cement grout is applied through the grouting pipe 70 by pressurized air so as to fill the clearance between the outer surface of the cylindrical members 61 and the tunnel. Furthermore, the reaction produced at the time of grouting will forcethe apparatus 30to advance.
Although this invention has been described with a certain degree of particularity, it is understood that the present disclosure has been made by way of example only and that numerous changes in the detail of construction and the arrangement and combination of parts may be resorted to without departing from the spirit and scope of the invention as hereinaf
