Method to push and inject pipe-shaped steel pipes so that the target objects can be purchased without affecting traffic flows or ground water without breaking roads, rivers, railways, etc. This has been commercialized in recent years.

The steel pipe propulsion pressurization method uses a tunnel that is slightly longer than the length of the unit steel pipe in the ground at the beginning of the point where the pipe member is to be buried, and then lays the steel pipe in the tunnel so that the tip of the steel pipe is directed toward the side wall of the tunnel. In the state, the propulsion mechanism (hydraulic jack, etc.) is used to push the rear end of the steel pipe forward to press the steel pipe into the ground, discharge the soil in the steel pipe, and then treat the other steel pipe as a predominant steel pipe (hereinafter referred to as 'leading pipe').

Accordingly, the present invention significantly improves the workability of the press-fitted pipe propulsion work, while providing an excellent effect of preventing the construction delay due to the construction error, that is, the occurrence of the error in the press-fitted propulsion direction, to shorten the air.

Hereinafter, a preferred embodiment of the present invention according to the accompanying drawings.

First, the propulsion direction adjustment device 1 of the press-fitting pipe according to the present invention, as shown in Figures 1 and 2, during the underground press-fitting construction of the pipe member (steel pipe), for example, the first press-fitted pipe When the member is disposed in front of the lead pipe 100 is pushed away from the center instead of being propelled in the originally planned direction when the pipe indentation construction, there is an embodiment feature to make it easy to adjust.

For example, FIGS. 3 to 5 show such a pushing direction adjusting device 1 of the press-fit pipe of the present invention.

That is, as shown in Figure 3, the propulsion direction adjustment device 1 of the press-fit pipe according to the present invention, the drive source 10 and at least one drive source (10) provided in the lead pipe 100 that is largely press-propelled underground, and the drive source ( 10) is configured in one embodiment including a propulsion direction adjustment unit 30 is provided to be linked to the front of the drive source to adjust the direction of the forward pipe propulsion according to the operation of the drive source.

Therefore, the propulsion direction adjustment device 1 of the press-fit pipe of the present invention is the ground pipe (G) 100 and the trailing pipe (100 ') by the propulsion mechanism 110, such as a hydraulic jack, as shown in Figs. When continuously press-propelled), if it is determined that (center) is deviating from the direction originally intended to be pushed, the construction worker stops the operation of the propulsion mechanism 110 for a while, and operates the drive source 10 of the present inventors It is to adjust the propulsion direction through the propulsion direction adjustment unit 30 associated with the drive source (10).

For example, as shown in FIG. 5, in the apparatus of the present invention, the driving source 10 to which the propulsion direction adjusting unit 30 is connected is, for example, 90 ° in all directions inside the lead pipe 100. A total of four or more (for example, six in total at 60 ° intervals) may be provided as actuators, that is, hydraulic cylinders, respectively, before, after, and left and right at intervals.

At this time, it is important that the hydraulic cylinder of each drive source 10 is connected to the hydraulic supply and discharge pipe (or may be a hose) 16a, 16b separately as shown in Figs. 3 and 5, such a hydraulic supply and The discharge lines are individually controlled so that each hydraulic cylinder is operated separately.

That is, as shown in Figure 4, when the drive source 10, which is a total of four hydraulic cylinders at 90 degrees intervals inside the lead pipe 100 is mounted, each hydraulic cylinder is a hydraulic pressure, such as a hydraulic pump outside the tube not shown The actuation (i.e., forward stroke) of the actuation member 12, ie actuation rod, is adjusted via an actuation unit (not shown).

For example, when only the hydraulic cylinder that is the driving source 10 of the upper pipe in FIG. 3 is advanced, the shoe member 34 of the propulsion direction adjusting unit 30 described in detail below is 'P1'-> 'P2'. When the position is adjusted, and thus the press-fitting is pushed, the pushing direction of the shoe member 34 is adjusted to 'T1'-> 'T2'.

As a result, the propulsion direction of the shoe member 34 of the propulsion direction adjusting unit 30 in front of the lead pipe is changed so that the propulsion direction of the lead pipe 100 or the trailing pipe 100 ′ which is subsequently press-fitted is adjusted. As a result, the pipe indentation propulsion work is carried out in the desired direction.

However, in FIG. 3, the pushing direction adjusting unit 30 enlarges the direction adjusting width, and in fact, the shoe member 34 of the pushing direction adjusting unit has a diameter of the lead pipe 100 as shown in FIGS. 3 and 4. In the corresponding tubular shape, its length is about 50 cm to 1 m, and the forward stroke of the hydraulic cylinder, which is the actual drive source 10, that is, the angle at which the shoe member 34 is twisted is very small.

Therefore, in the case of arranging hydraulic cylinders, which are a total of four driving sources 10 in FIG. 4, when one of the upper, lower, left and right hydraulic cylinders is advanced, the shoe member 34 propelled as the hydraulic cylinder operated as shown in FIG. 3. Only the part is advanced and twisted, the propulsion direction of the overall shoe member 34 can be adjusted.

On the other hand, as shown in Figure 5, the hydraulic cylinder which is the drive source 10 is fixed to the inner surface of the lead pipe 100, the connection bracket 14b provided on the front and rear of the body (unsigned) by welding or the like. To the fixed bracket 14a can be assembled with a bolt (B) or the like.

By the way, such a leading pipe 100 is a steel pipe is usually used, but is not necessarily limited to this, a concrete pipe or a tube made of high-strength glass-reinforced plastic (GRP) may be used, in this case, the hydraulic cylinder that is the drive source 10 It is also possible to manufacture the fixing bracket 14a itself in the form of a ring plate to fix the inside of the lead pipe to the lead pipe, and fix the connection bracket 14b provided on both sides or at least the rear side of the cylinder body to the lead pipe. Do.

On the other hand, as shown in Figure 5, the actuator, that is, the hydraulic cylinder, the drive source 10, as described above, in order to propel the shoe member 34 through the operation member 12, that is, the rod advancing as described above 16a and 16b are connected, and such hydraulic pipes are connected to an external hydraulic operation unit (hydraulic pump, etc.).

Such hydraulic pipes (hoses) are preferably connected to a hydraulic operation unit (not shown) such as a hydraulic pump by forming a hole in the fixing bracket 14a and the connecting bracket 14b located at the rear side of the hydraulic cylinder as the actuator. something to do.

Next, looking specifically at the propulsion direction adjustment unit 30 to enable the adjustment of the propulsion direction in the apparatus of the present invention, the propulsion direction adjustment unit 30, the operating member of the actuator which is the drive source (10) 12) the propulsion member 32 pushed by the propulsion member for propulsion block 18 is fixed to the rod and the propulsion member is fixed to the rod, and the propulsion member 32 is fixed in connection with the leading pipe provided in the form corresponding to the lead pipe Including the member 34, the shoe member may be configured to adjust the propulsion direction during the individual operation of the hydraulic cylinder that is the drive source 10.

Accordingly, as shown in FIGS. 3 and 5, when one driving source 10 disposed in the lead pipe, that is, the hydraulic cylinder, moves forward, the propulsion member propulsion block 18 mounted at the tip of the rod, which is the operating member 12, is provided. The pushing member 32 pushes the propulsion member 32 integrally, so that only the part of the tubular shoe member 34 in which the pushing member 32 is mounted on the inner surface is pushed, and the entire shoe is pushed. The pushing direction of the member is adjusted.

That is, the propulsion member propulsion block 18 for propulsion member mounted on the rod which is the hydraulic cylinder operating member is pushed forward in a state separated from the propulsion member 32 mounted on the shoe member 34 of the propulsion direction adjustment unit 30. do.

At this time, as shown in Figures 5 and 6, the pushing member 32 is a block form of a steel plate welded (W in Figure 5) or bolting form (Fig. 5) to the inner surface of the directional shoe member 34 (Fig. 6, B) can be fixed.

On the other hand, when bolting assembly, it is necessary to form a bolt hole (h) and bolt fastening groove (h ') in the pushing member 32 and the shoe member 34, respectively.

However, as described above, since the shoe member 34 is in the form of a tube having substantially the same diameter corresponding to the diameter of the lead pipe 100, it is easy to assemble the lead pipe and the shoe member and replace it if necessary. In order to facilitate, as shown in Figure 6, it will be preferable to assemble the pushing member 32 and the shoe member 34.

At this time, although not separately shown in Figure 6, it will be possible to assemble the bolt (B) is passed through the hole formed by forming the bolt fastening groove (h ') of the shoe member and fastened with a nut.

However, since the shoe member 34 is a hollow tube, the thickness of the shoe member 34 should be in the range of approximately 10 t to 20 t to enable the press-propelled protruding construction, so that the bolt B of the propelling member 32 as shown in FIG. 6 can be assembled. Do.

3 and 5, in the apparatus 1 of the present invention, the direction adjusting shoe member 34 fixed to the pushing member 32 of the pushing direction adjusting unit 30 is in the form of a tube. It is preferable that the tip 34a is tapered to facilitate the underground indentation.

Next, as shown in FIG. 7, in the device 1 of the present invention, the shoe member contact surface 32a of the propulsion member 32 of the propulsion direction adjustment unit 30, that is, the lower surface thereof is a tubular shoe member ( It is preferable to bend corresponding to the curvature of 34).

Of course, in such a press-fitted tube propulsion construction, the diameter of the leading pipe 100 or the shoe member 34 corresponding thereto is so large that the worker can handle the soil and the like introduced into the interior, so that the diameter of the shoe member is increased. Although the curvature is not large, it may be preferable to bend the close contact surface 32a of the propulsion member in order to closely adhere the pushing member and the shoe member.

Next, as shown in Figures 3 and 4, in the propulsion direction adjustment device 1 of the press-fit pipe of the present invention, from the driving source 10 to the actuator block 10 and the propulsion block 18 connected to the operating member 12. It is preferable that the enclosing body 50, that is, the cover body is fixed to the inner surface of the shoe member 34 to the pushing member 32 being pushed and propelled.

That is, a large amount of soil will be introduced through the shoe member during actual construction, and in this case, the soil may be caught between actuator moving parts such as an inflow cylinder, which is the driving source 10, and cause a malfunction thereof, at least the propulsion member 32. And the surrounding member 50 to surround the operating member 12 and a portion of the body of the inlet cylinder is required so that the soil is not caught.

Such a enclosure would have to be welded or bolted to the inner surface of the shoe member 34 in the form of a box.

On the other hand, the shoe member 34 of the present invention is pushed while being propelled while the rear end is in close contact with the front end of the lead pipe 100 when the leading pipe 100, the shoe member in the normal case except for changing the direction The propulsion of the propulsion is driven by the propulsion force of the trailing pipe (100 ') and the leading pipe (100) by the operation of the propulsion mechanism (110) (see Figure 1).

And, as shown in Figures 3 and 5, the pushing member 32 is a block shape having a length fixed in the form of a weld or screw on the inner surface of the directional shoe member 34, but part, that is, a part based on the center It is supported on the inner surface of the lead pipe (100).

Accordingly, a portion of the rear end portion of the propulsion member 32 mounted in all directions to the front, rear and left and right sides of the shoe member 34 which is substantially tubular in correspondence to the lead pipe is at least on all sides of the inside of the lead pipe 100. While being in close contact with each other, the fitted state allows the shoe member 34 to be positioned in front of the lead pipe, and the propulsion of the shoe member proceeds with the driving force of the lead pipe.

Accordingly, the pushing direction adjustment device 1 of the press-fit pipe according to the present invention described above, when buried in the ground by the push-in propulsion method, when the propulsion direction of the lead pipe deviates from the center, promptly sets the pushing direction immediately. It can be adjusted, facilitating overall construction and preventing air delay as the propulsion direction is distorted.

In particular, the structure is simple to provide practicality that can be easily mounted and used in various construction sites.

As mentioned above, although this invention was demonstrated in detail using the preferable embodiment, the scope of the present invention is not limited to a specific embodiment, Comprising: It should be interpreted by the attached Claim. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
