Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of attaching a pipe to an embedded object used for connecting a branch pipe to a sewer pipe buried in the ground.

[0002]

2. Description of the Related Art For example, in order to newly connect a branch pipe to a sewage pipe buried in the ground, a method of exposing the connecting portion of the sewage pipe to the outside by excavating the ground can be considered. However, in such a method, it is necessary to open and cut the ground widely, which is troublesome and expensive. In addition, for example, if the buried position of the sewer pipe is directly under the road, this construction will occupy the road widely and will have a large impact on the surroundings.

Therefore, conventionally, various attachment methods by non-cutting have been proposed. (1) In the mounting method shown in FIG. 11, first, the sheath tube 1
Underground UG while rotating 03 with an actuator
It is made to reach the sewer pipe 101 by pushing into. In this state, a mixture of earth and sand, groundwater, and pebbles (hereinafter simply referred to as earth and sand, groundwater, etc.) has entered the sheath pipe 103. Therefore, an auger 3 having a spiral blade
1 is inserted and arranged in the sheath pipe 103, and the auger 31 is rotated and moved forward to discharge the earth and sand, groundwater, etc. in the sheath pipe 103 to the ground.

Next, a sealant S composed of a coagulant, a water blocking agent or the like is injected between the sheath pipe 103 and the sewer pipe 101. By injecting this sealing agent S, the sheath pipe 103 and the sewer pipe 101
The attachment portion of and is sealed, and the surrounding space is prevented from entering the inner space of the sheath pipe 103. The injection of the sealant S is performed through the sealant passage 31α formed at the axial center position of the auger 31.
No. 1 rotates in the reverse direction of soil discharge / drainage, preventing backflow of earth and sand / groundwater.

Although not shown, the auger 31 is a sheath tube 10.
3, the blade of the drilling device is inserted and arranged in the sheath tube 103 instead. Therefore, by rotating the blade, a communication hole is formed in the outer peripheral surface of the sewer pipe 101, and the sheath pipe 103 is communicated with the inner space of the sewer pipe 101.
Then, by inserting and arranging the branch pipe into the sheath pipe 103, the branch pipe and the sewer pipe 101 are connected through the communication hole.

(2) The difference between the mounting method shown in FIG. 12 and the method (1) is that the thin pipe 32 reaches the sewer pipe 101 separately from the sheath pipe 103. The sealing agent S is injected from the peripheral side of the sheath tube 103 through the thin tube 32. Then, while the inner space of the sheath pipe 103 is sealed, the soil discharge / drainage in the sheath pipe 103 is performed by using the soil discharge / drainage device made of vacuum or the like.

[0007]

However, the following problems have occurred in each of the above prior arts. Prior art (1) The auger 3 is provided between the auger 31 and the sheath tube 103.
A slight gap is formed to make the rotation of No. 1 smooth. Therefore, even if the auger 31 is rotated in the reverse direction at the time of injecting the sealant S, the earth and sand, groundwater, etc. have entered into the sheath pipe 103 through the same gap. Therefore, there has been a problem that joining of the branch pipe to the sewer pipe 101 is uncertain and difficult because it is hindered by the earth and sand remaining in the sheath pipe 103.

Prior art (2) The injection of the sealant S is carried out not from the inner space side of the sheath tube 103 but from the embedding peripheral side, and is performed from a position eccentric to the sheath tube 103. For this reason, the flow of the sealing agent S is affected by the soil quality, and the sealing of the inner space of the sheath tube 103 is uncertain and uneven. Therefore, it is necessary to inject the sealing agent S over a wide range, and a large amount of the sealing agent S is required.

The present invention has been made by paying attention to the problems existing in the above-mentioned prior art, and the purpose thereof is to reliably discharge and drain the inside of the pipe body which has been propelled to the buried object and the buried object and the pipe. (EN) It is intended to provide a method for mounting a pipe body to an embedded object, which can surely seal a mounting portion with a body.

[0022]

Embodiments of the present invention will be described below. In addition, as shown in FIG.
In G, a cylindrical concrete sewer pipe 101 is embedded as a conduit. Then, the branch pipe 102 is newly connected to the sewer pipe 101 by the construction using the mounting method of the present embodiment. Further, in the second embodiment, only the differences from the first embodiment will be described, and similar members are denoted by the same reference numerals.

(First Embodiment) (Pipe Propulsion Step) As shown in FIG. 1, a cylindrical sheath pipe 103 as a pipe body is made of a steel pipe and is connected to a sewer pipe 101. (Shown in FIG. 7). The sheath tube 103 is set to the propulsion actuator 11 installed on the ground GS, and the actuator 11
It is driven into the underground UG by the air drive.

Then, as shown in FIG. 2A, the sheath pipe 103 propels the underground UG and reaches the sewer pipe 101,
A part thereof is in contact with the outer peripheral surface of the sewer pipe 101. Here, although not shown, a water pipe, a telephone line burying pipe, an electric wire burying pipe, etc. are buried around the sewage pipe 101, and in order to avoid them, the sheath pipe 103 is tilted with respect to the ground. Be promoted. Moreover, since the sewer pipe 101 is directly under the road and the road is not occupied by this construction,
The sheath tube 103 may be propelled obliquely from the side of the road. In the present specification, “reaching” includes, for example, not only the state that the sheath pipe 103 is brought into contact with the sewer pipe 101 (embedded object) but also the state that the sheath pipe 103 is close to the sewer pipe 101.

(Ejection / drainage process) FIGS. 2 (a) and 2
As shown in (b), sediment, groundwater, etc. have entered the sheath pipe 103 that has reached the sewer pipe 101 by propulsion. Therefore, in this embodiment, the partition wall 12 is the sheath tube 1.
03, and the soil and drainage in the sheath tube 103 is performed through the partition wall 12.

The partition wall body 12 is composed of a cylindrical body 12α having an outer diameter slightly smaller than the inner diameter of the sheath tube 103,
A seal member 1 made of synthetic rubber is provided on the outer peripheral surface of the cylindrical body 12α.
2β is fixed by a bolt or the like not shown. Therefore, when the partition wall 12 is inserted and arranged in the sheath tube 103, the front and rear of the partition wall 12 are sealed by the seal member 12β.

The partition wall actuator 13 is composed of a fluid pressure cylinder such as a hydraulic cylinder and is installed on the ground GS. The rod 13α of the actuator 13 is connected to the axial center position of the cylindrical body 12α. Therefore, the partition 12 is formed by the rod 13 driven by the actuator 13.
The expansion and contraction of α enables reciprocal movement along the inside of the sheath tube 103.

Injection hole 12 as injection hole for fluidity improving agent
γ and the discharge hole 12δ are respectively provided at positions slightly eccentric from the axial center position of the cylindrical body 12α, and the sheath tube 103
The inside and outside of the partition 12 are communicated with each other. One end side of the injection pipe 14 formed of a hose or the like is inserted and fixed in the injection hole 12γ of the partition wall body 12. The other end of the injection pipe 14 is connected to a water injection device 15 installed on the ground GS. Therefore, as shown by the arrow in the figure, the water injection device 15
By the action of the
Is supplied to the front side of the partition wall body 12 via.

Similarly, the discharge pipe 16 formed of a hose or the like has one end thereof inserted and fixed in the discharge hole 12δ of the partition wall body 12. Further, the other end of the discharge pipe 16 is connected to a soil discharge / drainage device 17 installed on the ground GS. The soil / drainage device 17 is provided with a vacuum or the like, and as shown by an arrow in the figure, earth / sand / groundwater existing on the front side of the partition wall 12 can be sucked out of the sheath tube 103 by its suction force.

Now, in this step, the partition wall 12
Is inserted and arranged in the sheath tube 103 from the opening on the GS side on the ground.
When the partition wall actuator 13 extends the rod 13α, the partition wall 12 is given a moving force in the sheath pipe 103 toward the sewer pipe 101. Water injection to the front side of the partition wall 12 is started by the water injection device 15 at approximately the same time as or immediately before the application of this moving force. Therefore, water (fresh water) is mixed with the earth and sand, groundwater, etc. located in front of the partition wall 12 in the sheath tube 103, and the flow characteristics thereof are improved.

Sediment in the sheath pipe 103 with enhanced fluidity
Groundwater and the like are discharged to the outside of the sheath pipe 103 through the discharge pipe 16 by the suction action of the soil discharge / drainage device 17. Further, the earth and sand, groundwater, and the like in the sheath pipe 103 are pressurized by the partition wall 12 to which the moving force is applied, and the discharging action is also exerted by this pressure. In this way, the partition 1
2 is a drainage pipe 101 inside the sheath pipe 103 while discharging and draining soil.

(Sealant Injection Step) As shown in FIGS. 4, 5A and 5B, the sheath pipe 103 and the sewer pipe 101
A sealing agent S made of a coagulant, a water blocking agent or the like is injected between the two, and the inner space of the sheath pipe 103 is sealed from the earth and sand, groundwater, etc. around the buried portion. Here, in the present embodiment, the sealing agent S is injected through the partition wall (12), as in the soil discharging / draining step. Further, as the partition wall body (12), the partition wall body 12 which has reached the sewer pipe 101 by the completion of the soil discharge / drainage process is used as it is. Therefore, in this step, the injection hole 12γ functions as a sealant injection hole.

Now, as shown in FIG. 4, the partition wall 12
The water injection device 15 is removed from the injection pipe 14, and an injection device 18 is connected instead of the water injection device 15. Also,
The valve 19 arranged in the middle of the discharge pipe 16 is closed, and the discharge pipe 16 is closed. And FIG.
As shown in (a), the sealant injection device 18 injects the sealant S through the injection pipe 14. The sealing agent S is supplied to the front side of the partition wall 12 through the injection pipe 14 and the injection hole 12γ, and is filled between the partition wall 12 and the outer peripheral surface of the sewer pipe 101. As shown in FIG. 5 (b), a part of the sealant S is flown to the outside through the gap between the sewer pipe 101 and the sheath pipe 103, and the sealant S causes the inner space of the sheath pipe 103 to be soil. -It will be sealed from groundwater.

(Communication Step) As shown in FIG. 6, the partition wall 12 is taken out of the sheath tube 103 to the ground GS. The drilling device 20 is arranged on the ground GS, and the cylindrical blade 20α thereof replaces the partition wall 12 and the sheath tube 1
It is inserted in 03. Then, the blade 20α is rotated while being in contact with the outer peripheral surface of the sewer pipe 101, so that a communication hole 101α is formed in the peripheral wall of the sewer pipe 101. Therefore, the sheath pipe 103 and the sewer pipe 101 are connected via the communication hole 101α. The communication hole 101α
Is formed to have a diameter substantially the same as the outer diameter of the branch pipe 102.

As described above, the attachment of the sheath pipe 103 to the sewer pipe 101 buried in the underground UG is completed. Next, a process of connecting the branch pipe 102 to the sewer pipe 101 will be described.

(Branch pipe inserting / fixing step) As shown in FIGS. 7 and 8, a branch pipe 102 made of a synthetic resin (for example, vinyl chloride) is inserted into a sheath pipe 103, and the communicating hole 101 is formed.
It is arranged so as to project into the sewer pipe 101 via α. The filler C such as mortar or concrete is filled by the pump device 21 into the space formed between the sheath pipe 103 and the branch pipe 102. Then, the branch pipe 102 is fixed in the sheath pipe 103 by solidifying the filler C. In this way, the branch pipe 102 is connected to the sewer pipe 101, and the branch pipe 102 is connected to, for example, a sewer pipe of a house (not shown).

Therefore, the work of drilling the communication hole 101α is performed by an operator from the inside of the sewer pipe 101 using a drilling device (not shown). The diameter of the communication hole 101α is the sheath tube 103.
It has been expanded to about the inner diameter of.
