Description

A settlement structure for gap of a concrete box}

The present invention relates to a structure for filling the connection of the concrete box, in particular, by filling the space between the connection and the side wall of the concrete box with a simple construction to improve the workability and productivity, as well as to ensure the gap filling more concrete box It relates to the pore treatment structure of a concrete box to minimize the defects.

In general, in the case of a passage through which people can pass or a passage through which an electric vehicle passes, a concrete box is constructed by using reinforcing bars and concrete, and the concrete box is assembled between sidewalls formed at both sides. It is constructed in the form of a tunnel.

That is, the concrete box, as shown in Figure 1, is provided with a box body 101 is formed a predetermined space in the longitudinal direction therein, the pillar 102 in the vertical direction in the center of the box body 101 Is formed, is formed on the outer wall 103 to the left and right around the pillar 102, respectively, the construction joint 104 is formed in the upper and lower portions of the outer wall 103, respectively.

However, when the concrete box 105 is installed in a subway attachment part, groundwater penetrates into the construction joint 104 and leaks occur, thereby lowering the structural strength of the concrete box 105. There is a problem, such as a poor space between the concrete box 105 and the side wall at the time of backfilling after completing the construction of the subway opening, there was a problem such as poor compaction.

Therefore, the present invention was devised to solve the above-mentioned problems, and the concrete box is made by filling the space with the connection part and the side wall of the concrete box by simple construction to improve the workability and productivity, and to make the void filling more certain. The purpose is to provide a pore treatment structure of a concrete box to minimize the defects.

The present invention for achieving the object of the bar is provided with a concrete box, each of which is provided with construction joints on the upper and lower sides of the left and right outer walls, the side walls are formed at regular intervals on the left and right sides of the concrete box, the side wall and the concrete box The grouting tube is fixed to the space between the outer walls of the vertical direction, and a plurality of ejection holes are formed in the grouting tube so that the grout can be injected through the ejection holes.

That is, the voids of the concrete box can be filled through the grouting pipe as described above, and the grouting pipe is fixedly installed in the vertical direction in the space between the outer wall and the side wall of the concrete box, resulting in the construction joint or sidewall of the concrete box. It will be able to fill the gap.

Therefore, the voids can be more effectively treated to the structures forming the subway openings, thereby improving the strength of the structures and supplying grout to the underground structures more effectively from the ground, thereby improving the maintenance and construction of the structures, and the work of the workers. This can improve productivity and productivity.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a state diagram showing a pore treatment structure of a concrete box according to the present invention, Figure 3 is a perspective view showing a grouting tube used for the pore treatment of a concrete box according to the present invention.

Referring to the structure of the present invention by the above drawings, the structure for processing the voids of the concrete box (1) or the side wall (2) installed in the subway attachment portion, the construction joints respectively on the upper and lower parts of the left and right outer walls (3) A concrete box 1 having a portion 4 formed thereon is provided, and side walls 2 are formed at predetermined intervals on the left and right sides of the concrete box 1, respectively, and an outer wall of the side wall 2 and the concrete box 1 is provided. (3) the grouting pipes 5 are fixed to the spaces in the vertical direction, and a plurality of ejection holes 6 are formed in the grouting pipes 5 to inject grout through the ejection holes 6. It's a structure.

Here, the characteristic of the structure for processing the voids of the concrete box 1 is the grouting pipes 5 are respectively installed in the vertical direction between the outer wall 3 of the concrete box 1 and the side wall 2 of the subway attachment portion, By supplying the grout through the grouting tube (5) as needed, it is possible to return the construction joints (4) of the concrete box (1) or to fill the space between the outer wall (3) and the side wall (2) will be.

In other words, the grouting pipe (5) can fill the voids of the concrete box (1), the grouting pipe (5) in the space between the outer wall (3) and the side wall (2) of the concrete box (1) ) Is fixed in the vertical direction to fill the voids generated in the construction joints (4) or side walls (2) of the concrete box (1).

That is, as shown in FIG. 3, the grouting pipe 5 is installed outside the concrete box 1 of the subway attachment portion, and the grouting pipe 5 has a plurality of ejection holes 6 formed at regular intervals. Through the blowout hole 6 is to be able to supply the grout to the structure.

In addition, the grouting pipe 5 is embedded in the outer side of the concrete box 1, when the construction of the concrete box 1 is completed, the left and right on the space between the outer wall (3) and the side wall (2) of the concrete box (1) Each grouting pipe 5 is fixedly installed in the vertical direction, and the grout is injected into the grouting pipe 5 to backfill the side wall 2 and the upper part of the concrete box 1, and grouting when repairing the road surface. After installing the cap on the upper part of the pipe (5) and permanently embedded, reinforcement grouting can be performed at the injection position of the ground during leakage and ground subsidence.

Therefore, when backfilling the side wall (2) to improve ground subsidence and to prevent leakage of the structure, the grouting pipe (5) having a diameter of about 20-50 mm is buried to the ground and then reinforced in the place of severe leakage during the use of the structure. It is possible to facilitate the control of leakage of groundwater by performing grouting, and to control the ground subsidence due to the air gap in the deep depth by injecting reinforcement grout when the pile is removed after completion of the attachment structure.

As described above, according to the pore treatment structure of the concrete box according to the present invention, the pore treatment can be more effectively performed on the structure forming the subway opening part, thereby improving the strength of the structure and supplying grout to the underground structure more effectively from the ground. As a result, maintenance and construction of the structure are improved, and the workability and productivity of the worker can be improved.
