Description

Inducing waterproof structure of underground diaphragm wall

The present invention relates to an induction waterproof structure of the underground continuous wall for preventing the leakage phenomenon of the concrete joint formed by the joint in the construction of the underground continuous wall.

Top construction is one of the construction methods that can be constructed without adversely affecting the adjacent ground in urban construction.

The top-down method is one of the underground structure construction methods that simultaneously perform the super structure and sub-structure construction in the downtown area, and it is a high rigid wall such as diaphragm wall or caisson wall when constructing the underground wall. ), And the excavation for the construction of the underground structure after construction is excavated from the ground floor to the bottom, and at the same time, the construction of ground frame construction is expected to reduce the overall air.

In addition, the method supports underground diaphragm walls in place of wales or struts, thereby preventing settlement of nearby ground and buildings, and at the same time preventing damage to underground works. It is possible to carry out underground construction structurally safely.

On the other hand, when the construction of the underground continuous wall, there is a case that concrete is not treated tightly in the concrete joint, there is a fear that the ground water and the like flow into the interior through the back of the underground continuous wall (Fig. 2).

That is, since it is always exposed to the water pressure, earth pressure and chemical components of the underground continuous wall, leakage may be accompanied through structurally fragile parts such as construction joints or expansion joints.

Therefore, in order to prevent such a leakage phenomenon and to secure the water quality of the joint portion, the method of reinforcing the coating film waterproof after filling the mortar, the method of injecting the urethane-based index material, the method of extracting a certain portion of the cross section and then waterproofing the permeable liquid. Alternatively, the interlocking pipe can be installed to increase the construction precision of the joint and minimize the leakage, or by over cutting one side of the continuous wall without installing the end end pipe. The method was used.

However, these methods are inefficient because they lead to an increase in air and construction costs, or there is a possibility that additional waterproof measures should be taken by changing the underground water channel to a new part rather than being a fundamental waterproofing method.

The present invention created to solve the above problems is to provide an induction waterproof structure of the underground continuous wall that can fundamentally block the leakage phenomenon through the concrete joint in the underground continuous wall.

In order to solve the above problems, the present invention is a hose which is inserted along the longitudinal direction of the joint to the joint portion formed by digging a groove along the length or width direction of the underground continuous wall; And a waterproof layer formed by filling a mortar on an upper part of the joint into which the hose is inserted. Consisting of, the hose provides a guided waterproof structure of the continuous underground wall, characterized in that a plurality of stainless steel is arranged in a mesh along the circumference of the hose.

That is, in the present invention, since the hose is drained by inserting a hose arranged in a mesh along the circumference of the joint portion, it is possible to prevent an additional leak phenomenon by not changing the existing water flow path.

In the case of constructing the continuous continuous wall using the present invention as described above, since the waterproof construction can be performed without changing the existing water flow path, additional leakage can be prevented.

In addition, since corrosion-resistant stainless steel is used as a material, economical construction is possible by adopting a semi-permanent system that requires no maintenance and repair.

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

2a to 2c is a cross-sectional view showing a step-by-step process for the construction of the induction waterproof structure of the continuous underground wall 10 in accordance with the present invention.

Induction waterproof structure of the underground continuous wall 10 of the present invention is a hose inserted along the longitudinal direction of the joint 20 in the joint 20 formed by digging a groove along the length or width direction of the underground continuous wall (10) 30; And a waterproof layer 40 formed by filling a mortar on the joint 20 into which the hose 30 is inserted. It is made, but the hose 30 is characterized in that a plurality of stainless steel mesh is arranged along the circumference of the hose (30).

For the construction of the induction waterproof structure of the underground continuous wall 10 as described above, first, as shown in FIG. 2A, a groove 20 is formed by digging a groove along the length or width direction of the underground continuous wall 10.

At this time, considering that the leakage occurs mainly along the construction joint (construction joint) portion caused by pouring new concrete to the hardened concrete, the joint 20 of the present invention is preferably formed along the construction joint portion Do.

In addition, the joint 20 is formed by cutting into a V-shaped cross-sectional shape using a diamond cutter or a breaker, etc., the depth of the joint 20 is greater than the diameter of the hose 30 so that the hose 30 can be sufficiently inserted, To ensure workability and durability, the thickness of concrete should be less than.

Next, as shown in FIG. 2B, the hose 30 is inserted into the joint 20 along the longitudinal direction of the joint 20.

In this process, before inserting the hose 30, it is preferable to remove impurities, latencies, and the like deposited on the surface of the underground continuous wall 10, and to wash them.

In the present invention, the hose 30 is characterized in that a plurality of stainless steel is arranged in a mesh along the circumference of the hose (30). That is, since a plurality of stainless steels having excellent strength and corrosion resistance are arranged in a mesh form, they are not corroded by externally introduced chemicals and thus have durability.

In addition, the hose 30 has to be flexible to be able to be inserted irrespective of the smoothness of the underground continuous wall 10, and select the diameter of the hose 30 by predicting the quantity of induction water.

On the other hand, the hose 30 is guided to the inside of the hose 30, the guided water drawn through the underground continuous wall 10 to the joint 20 portion to drain along the longitudinal direction of the hose 30 In this case, in order to prevent the groundwater from flowing into the room, part of the surface of the hose 30 facing the indoor side may be coated with PVC or the like.

In addition, the hose 30 may be coupled to the upper portion of the underground continuous wall 10 by fastening a coupling pin through a space formed between stainless steel arranged in a mesh. In this case, the coupling pin inserts the coupling pin in parallel with the cutting surface cut in V-shape to form the joint 20 so that one end does not penetrate the joint 12.

In addition, the hose 30 is inserted into the joint 20, and the band is made of stainless steel to cover the outer circumferential surface of the hose 30, and then the coupling pins are fastened to both ends of the band to fix the hose 30. Method is also possible.

The lower end of the hose 30 that is fixed in this way is connected to the drainage line of the structure, to drain the induction water to the outside.

Finally, the mortar is filled on the joint 20 into which the hose 30 is inserted to form a waterproof layer 40 (FIG. 2C).

Here, mortar uses a waterproof mortar, and the distance from the surface of the underground continuous wall 10 to the outer circumferential surface of the hose 30 is maintained at 18-20 mm or more.

While the invention has been described in connection with the preferred embodiments as mentioned above, various modifications and variations are possible without departing from the spirit of the invention. Therefore, the claims of the present invention include modifications and variations that fall within the true scope of the invention.
