DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for constructing a guide wall in a method of burying a pipe.

[0002]

2. Description of the Related Art In recent years, when a pipe such as a sewer pipe is sunk in a slot and buried therein, a plurality of pipes are replaced by a so-called open-cutting method in which a pipe is sunk into a slot and connected one by one. A method of submerging a group of pipes in a submerged trench filled with a stabilizing liquid and connecting them to each other or to a human hole (manhole) is widely used to minimize traffic stoppage, particularly in a city.

[0003] The outline of the submerging method by the stable liquid excavation will be described. First, as shown in Fig. 1, guide walls 1, 1 are constructed at the submerged position of a pipe P and on both sides of a human hole M, M. . The guide wall serves as a support surface for a digging device such as a power shovel, a hoisting / lowering device such as a crane, and a hanging support member such as a erection member. Then, although not shown, a predetermined distance from the starting end side manhole portion M between the guide walls 1 and 1, for example, to the next manhole portion M, is buried by a power shovel or the like while filling with a stable liquid B such as bentonite muddy water. While excavating ditch D,
At least the starting end of the submerged groove D is inserted into
To sink.

On the ground, on the ground, as shown in FIGS. 2 and 3, a plurality of pipes P, P,... A lower support member 4 such as a shaped steel is applied, and the lower support member 4 is wound around a pipe P with a wire 5 or the like to be integrated. A plurality of couplers 6 are fixed to the upper surface of the upper support member 3 of the integrated connection pipe PU at intervals in the longitudinal direction.
Gevin bar (screw steel bar) for position monitoring and hanging support
7 is screwed.

After the completion of the setup, for example, the connecting pipe PU is connected to the connecting pipe PU via the wire 5 wound around the connecting pipe PU by the chain block 9A using the portal crane scaffold 8 assembled as a structure as a support. Is suspended, and the support by the chain 9B is sequentially dropped, and is suspended and lowered to a position where the human hole 2 is to be connected. FIG. 3 shows this subsidence completion state. Thereafter, as shown in FIG. 4, the erection member 20 erected between the guide walls 1 and 1 is connected to the suspension support Gevin bar 7 by a nut 21 to suspend and support the connection pipe PU.

Next, whether or not the connecting pipe PU is suspended and supported at the design position (depth direction position and groove width direction position) is determined by the Gevin rod 7 projecting from the stable liquid level and the predetermined portion of the pipe body. Is confirmed by the position of the uki F connected via the connecting yarn. When the sunk position of the pipe is shifted, an H-section steel is erected on the side of the sunk pipe, and the H-section steel is pressed against the side of the pipe and moved in the groove width direction to adjust the sunk position. .

Thereafter, a solidifying material such as cement milk is poured into the stabilizing liquid B in the submerged groove D, and air is stirred to solidify the stabilizing liquid B. After the completion of the solidification and a curing period of about one week, a worker infiltrates the human hole 2 and digs a solidified muddy portion as shown in FIG. The short pipe P 'for connection is inserted from the inside of the human hole 2 into this through-passage, and the space around the short pipe P' is filled with mortar to stop water.

Conventionally, in such a pipe burying method, in order to construct a guide wall, prior to excavation of a buried trench, a guide wall construction portion on both sides thereof is excavated, and a desired sectional shape is shown in FIG. 19 (A), for example. The grooves 100, 100 having a hook-shaped cross section are formed as described above, and then the concrete 1 is placed in the grooves 100, 100 as shown in FIG.
01 and 101 were installed to construct a guide wall.

[0009]

However, such a conventional method is basically based on the casting of concrete on site, and is suitable for work such as the work of spreading concrete at the time of casting and the leveling of the surface of the poured concrete. However, there is a problem that it takes much time and effort.

[0010] Accordingly, a main object of the present invention is to reduce the time and effort required to construct a guide wall and to speed up and simplify the construction work.

<Advantages> As can be easily understood from these embodiments, the present invention has the following advantages as compared with the conventional concrete casting in place. (A) In the present invention, it is not necessary to level the surface because the consolidated material is only injected into the guide wall construction target site such as the roadbed layer. Therefore, compared with the conventional example, the present invention can be performed quickly and easily without requiring any labor.

(B) Comparing the construction work of the casting groove and the casting work by laying out the concrete with the construction work and the casting work of the pouring groove of the present invention, the present invention requires less labor and is quicker and easier. Can be done.

(C) In particular, when the apparatus of the present invention is used as in the above-described example, the construction work of the injection groove (the work of cutting the pavement surface along the edge of the buried position) and the injection work can be performed simultaneously, so that labor Can be remarkably reduced, and the work can be significantly speeded up and facilitated.

<Others> (A) The method and apparatus of the present invention can be applied to any type of pavement. Although not shown, for example, a subbase layer composed of a lower subbase and an upper subbase is laminated on a subgrade including a barrier layer as an upper surface layer (embankment or ground), and a prime coat layer as an upper layer is arranged in order from the bottom, In addition to asphalt concrete pavement having a structure in which a base layer, a tack coat layer, and a surface layer are laminated, in place of an upper layer in this asphalt concrete pavement, asphalt emulsion or basement paper and cement concrete pavement having a cement concrete surface layer, asphalt concrete pavement, And it can be applied to a simple pavement in which the tack coat layer is omitted.

The present invention can also be applied to a case where a guide wall is constructed on an unpaved road.

(B) The method of the present invention can be performed without using the construction apparatus of the present invention. For example, as shown in FIG. 18, excavation of the buried trench D is performed by a digging device BH such as a backhoe, and a wall construction target portion 40 on both sides of the buried trench D at a position behind the backhoe BH in the excavation traveling direction.
For example, as shown in the figure, while moving the injection pipe 12 along the side surface 43 of the site, a solidification material is injected and solidified (B indicates a solidified body) to form a guide wall,
Although not shown, before the excavation of the submerged groove, the injection pipe penetrates without forming a cutting groove or the like in the guide wall construction target portion on both sides of the submerged groove, and the consolidated material is inserted into the construction target portion through the injection pipe. Injection and solidification are also included in the present invention.

(C) The guide wall construction apparatus of the first embodiment is based on an asphalt cutter having a disk-shaped cutter blade, but may be based on another type of pavement cutter. Although not shown, the cutter device and the injection pipe may be separated from each other. For example, the injection pipe may be mounted on a dedicated carriage, and the injection operation may be performed while moving the injection pipe carriage following the cutter apparatus. .

(D) As the solidifying material, a known hardening material such as a cement hardening material or a water glass hardening material can be used.
