Field of the Invention The present invention relates to a soil injection press-in propulsion device capable of easily changing the horizontal and vertical propulsion directions of the installed propulsion device in an installation work of the soil injection press-in propulsion device for digging an underground horizontal excavation path. Related to the installation correction tool.

[0002]

2. Description of the Related Art Conventionally, telephone lines, electric cables for power transmission, water pipes, and the like are buried under roads, and during construction, disposal of residual soil (industrial waste) caused by closing or excavation of roads. In order to solve the problem, without excavating the buried place, provide shafts at both ends, press-fit the propulsion pipe in the horizontal direction from one shaft to the other, and perform wiring etc. in this propulsion tube There is a construction method. In order to measure the exact propulsion position of the propulsion pipe, a tip device equipped with a sensor for detecting the position of the propulsion pipe is provided at the head of the propulsion pipe. Until now, the propulsion device installed at the bottom of one of the shafts pushed the tip device and a plurality of propulsion tubes to cut the propulsion path.

[0005] FIG. 5 is an explanatory view showing a state in which the above-mentioned digging press-in propulsion device is carried into a shaft, in which 20 is the shaft, 21 is an opening of the shaft 20, and 22 is an opening of the shaft. Shaft 2
0, an inner bottom portion 23 is installed on the inner bottom portion 22 of the shaft 20, and a propulsion device for pushing a propulsion pipe into the ground, 24
When the propulsion device is installed on the inner bottom portion 22, a wire rope suspended from the propulsion device 25 is connected to the propulsion device 23.
It is a propulsion pipe that is buried in the ground and is used for wiring and the like. In order to bury communication lines such as telephones, the shaft 20 usually has a depth of about 5 m and a vertical length of 5 m on the inner bottom surface.
A shaft with a size of up to 6 m and a width of 1 m to 2 m is opened.

[0004] The opening 21 of the shaft 20 is often cut along a road, and the opening 21 has a small area so as not to inconvenience vehicles and pedestrians who use this road, such as blocking traffic. Is required.

[0005] The propulsion device 23 is provided with the propulsion pipe 2.
5 for injecting into the soil from one of the shafts, and has a length of 4400 mm to 5460 mm and a width of 800 mm to
It has a size of about 1270 mm and a height of about 1440 mm to 1500 mm, and has a weight of about 3 t to 4 t because the propulsion pipe is pushed into the ground with a large pressure.

[0006] Such a propulsion device 23 is provided with the shaft 20.
The wire rope 24 is wound around a propulsion device 23 which is loaded and carried on a carrier such as a truck, and is loaded using a crane truck or the like. , Hanging and installation work.

[0007]

Between the opening 21 and the inner bottom 22, there are often various buried pipes which are already buried, such as water supply, electricity and gas, which are indispensable for city life. In this installation work, it is often necessary to sew the existing buried pipes carefully so as not to damage them. Therefore, as described above, this installation work is performed by suspending the propulsion device 23 vertically or obliquely in the opening 21 of the shaft 20 which is relatively narrow and excavated, while removing the existing pipe. It was an installation work with a gap between them, which involved considerable difficulty. That is, as described above, when a shaft is excavated on a road, the opening cannot be widened, so that the propulsion device suspended by a wire rope must be carried into the shaft at an angle, and for example, a telephone When a shaft is excavated for wiring, other pipes such as water pipes and electric cables may already be exposed between the road and the inner bottom of the shaft. Since the position is below other pipes, the propulsion device suspended by a wire rope must be carried in through the gap between the pipes and installed at the target position so as not to damage these pipes. In addition, these tasks were very difficult. For this reason, as one method, there is a method of dividing the propulsion device, carrying it into the bottom of the shaft, and assembling it at the bottom of the shaft. Therefore, the time required for installing the propulsion device is to be increased. Furthermore, as described above, since the propulsion device has a very heavy weight of 3t to 4t, once it is installed on the bottom 22 of the shaft, even if there is a slight shift in the installation position, it will be It was very difficult to change the installation position. Also,
If the propulsion direction of the propulsion pipe from the shaft to other target shafts is not injected into the target propulsion direction, a drastic increase in the tip equipment provided at the head of the propulsion pipe Direction correction is required, which causes a problem that the buried propulsion pipe meanders in the ground.

[0008] The present invention has been made in view of the above-mentioned conventional circumstances, and even if the propulsion device, which is a heavy equipment, is not accurately installed at a target position, the propulsion device may not move horizontally after provisional installation. It is an object of the present invention to provide an installation correction tool for a soil-intrusion press-in propulsion device that can easily correct the position and vertical position.
