Description

Crack filling repair-apparatus of structure and the watertight method}

The present invention relates to a crack filling repairing device and a waterproof construction method of the structure, and more particularly, in the case of voids such as cracks in and out of the structure due to the internal and external deformation of the structure, the washing water and crack prevention and waterproofing on the crack part The present invention relates to a crack filling repair device for a structure and a waterproof construction method thereof, which allow the sealing material to be sequentially inserted to fill a microgap.

In general, the structure consists mainly of concrete structures, such concrete When a structure is over a long time, cracks such as cracks occur inside and outside the building when torsion by external force or when water evaporates from the structure after construction of a new building.

As the crack occurs, water leakage occurs, and when the life of the structure is prolonged, the structure collapses in severe cases.

In addition, in the case of new buildings, if the leakage is confirmed during the check after the waterproof construction, there is a problem in that the economic cost greatly increases due to the overall reconstruction.

Therefore, conventionally, various methods of repairing and waterproofing devices have been proposed in order to prevent cracks and leaks of such buildings, and as an example, there is a waterproofing method of a building structure proposed in Patent No. 180959.

This drills a hole 1 in the leak location of the structure as shown in FIG. 1, and inserts a pipe 3 in which the insertion end is divided into a crown and a packing 2 is fitted into the hole 1. , By connecting the hose (5) of the pump (4) for pumping the filler (6) mixed with a water-soluble waterproofing material, water, cement, water to the pipe (3) to the filler (6) by the pump (4) By leak coagulation to the leaking part to prevent leakage of the building.

The waterproofing method as described above is constructed as a sequence of inserting a pipe into the structure and then supplementing the insertion portion and then inserting the mixed filler, which can seal the cracked portion of the part which is not visible to the naked eye and also the structure of the leaking place. It has the advantage of not having to remove it. However, in this method, the filling material is injected into the construction process The problem of continuous injection effect and the delay index when the injection material is suddenly lost to a gap other than the required gap cannot be combined at the same time, and there is also a problem. It can be easily penetrated and solidified, but when micro voids are generated, the filler that is penetrated often does not penetrate into the gap and solidifies frequently. Also, the path that is transferred as it is transported through the pipe from the filler reservoir to the cracked portion. Due to the difference in pot life and specific gravity of the material in the bed and the change in physical properties, a serious problem of blocking the supply path occurs.

In addition, there is a problem that the solidification time and the water tightness after the solidification during the solidification of the filler decreases as the same filler is added regardless of the pore size of the crack.

Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to first inject the washing water into the micro-gap of the crack generated according to the internal and external deformation of the building structure, and then check the pressure according to the washing water injection and correspondingly By injecting the fillers, the fillers hydrate and react with the washing water so that they can quickly penetrate into the microgap and solidify, and at the same time, by selectively mixing and filling the corresponding fillers according to the gap characteristics of the construction site, The gap is stably sealed to improve the watertightness.

In addition, when material loss occurs in a gap other than the filling part, the delayed index material is injected through a valve member separately provided to the multi branch pipe, thereby preventing the loss of the filling material, thereby reducing work efficiency and economic cost. I can make it happen It is.

DESCRIPTION OF SYMBOLS 10 Metal pipe 20 Mixing pipe 21 Mixing element 30 Multiple branch pipe 40 Valve member

The present invention for achieving the above object is a metal pipe forcibly poured into the insertion portion formed on the concrete construction wall surface; A mixing tube assembled to an exposed end of the metal pipe and having a mixing element embedded therein; A multiple branch pipe installed at an exposed end of the mixing pipe, each of which presents a plurality of suction pipes; And valve members fitted to each of the connection parts of the multi-branch.

Hereinafter, a crack filling repair apparatus for a structure according to the present invention will be described in detail with reference to the accompanying drawings.

According to the present invention, the metal pipe 10, the mixing pipe 20 incorporating the mixing element 21, the multi branch pipe 30, and the valve members 40 are connected to each other.

One end of the metal pipe 10 is poured into the insertion hole 50 which is drilled in the concrete construction wall by a drill, and a threaded portion 11 is formed at the exposed end thereof.

And, the screw portion 11 of the metal pipe 10 is provided with a joint pipe 12 to be screwed with one end of the mixing pipe 20, the outer side of the joint pipe 12 when the metal pipe ( 10) and the lever 13 to open and close the mixing tube 20 is provided.

In addition, the mixing tube 20 is provided with a mixing element 21 therein to mix the incoming material. In addition, the multi-distribution pipe 30 is screwed to the other end screw portion 22 of the mixing pipe 20, the multi-distribution pipe 30 is a plurality of suction pipes (31) (31a) (31b) on the outside in one piece Is provided in communication with each of the suction pipes (31) The valve members 40 are respectively coupled to the exposed end screw portion.

And, the coupling end of the valve member 40 is provided with a lever 42, respectively, to open and close the passage to the multi branch pipe (30).

Here, the valve members 40 are for injecting the washing water and the filler which is a mixed material, and are divided into first, second, and third valve members 41, 41a, 41b, and the first valve member ( 41 is screwed with the suction pipe 31 to supply the washing water to the hole 50 through the mixing pipe 20 and the metal pipe 10, the second and third valve member (41a) (41b) Each of the suction pipes 31a and 31b is screwed into the mixing pipe 20 to selectively supply the mixed material according to the characteristics of the void gap, that is, a filler and an index material having viscous force and fluidity.

In addition, when the washing water is supplied to the crack gap through the metal pipe 10, the foreign matter is removed to secure the passage, and when the pressure penetrates into the gap extending from the crack gap, the worker checks the crack gap. Make sure to check.

With reference to the accompanying drawings, the installation and working state of the crack filling repair device of the structure as described above will be described in detail.

First, the worker detects whether the main reinforcement, electricity, gas pipes, etc. are buried in the concrete cracking area using a metal detector, and then drills the holes 50 with the drill to avoid the position where they pass, and then the holes 50 Pour one end of the metal pipe (10). Subsequently, the exposed end of the metal pipe 10 is screwed into the mixing pipe 20 via the joint pipe 12, the exposed end of the mixing pipe 20 The multiple branch pipes 30 are screwed together, and the suction pipes 31, 31 a and 31 b of the multi branch pipe 30 are successively provided with first, second and third valve members 41 and 41 a ( The assembly is completed by inserting and fixing each 41b).

Here, the inner diameter Ø1 of the hole 50 formed in the concrete cracking portion is formed smaller than the outer diameter Ø2 of the metal pipe 10 as shown in FIG. 3 so that the metal pipe 10 has a hole 50. ) To be fixed by pouring.

When the assembly is completed in this way, the operator first rotates the lever 42 of the first valve member 41. Then, the first valve member 41 is opened, and the washing water is introduced into the hole 50 at the concrete construction site through the mixing pipe 20 and the metal pipe 10. Continuously, the washing water is introduced into the void gap extending from the hole 50 of the concrete construction site. At the same time, when the washing water is completely filled with the crack gap, the washing water is excessively supplied and the supply is stopped. The pressure acts in the 30.

At this time, the operator can determine whether the gap between the cracks is large or small by the washing water supply pressure in the multi-distribution pipe 30.

That is, when the washing water is gradually supplied by applying a constant pressure to the cracks while the washing water is sufficiently filled, high pressure is applied when there is a minute gap in the crack, and low pressure when there is a gap extending from the crack. In this case, the operator can check whether there is a minute gap in the crack.

In other words, when the measured pressure is low, when the washing water supplied through the first valve member 41 Since it is judged that the supplied washing water is gradually progressing to a gap extending from the cracked part, the operator interrupts the washing water supply by blocking the lever 42 of the first valve member 41 while the washing water is sufficiently supplied. At the same time, the lever 42 of the second valve member 41a which supplies the material having a relatively high viscosity and fluidity is opened to transfer the materials to the mixing pipe 20. The material having high viscosity and fluidity transferred to the mixing tube 20 is rapidly mixed into the crack gap by affinity with the washing water while being passed through the metal pipe 10 while being mixed by the mixing element 21 and relatively voids. It fills up this large gap and gradually solidifies to fill the crack.

On the other hand, if the measured pressure is high, it is determined that there is a fine gap in the crack gap portion, and at this time, by supplying a material having a relatively low viscosity to the mixing pipe 20 through the third valve member 41b, The low-viscosity material is transferred to the fine gap of the crack gap in the state of being mixed by the mixing element 21 of the mixing tube 20, and is made to be filled.

In the present invention provided as described above, in order to obtain a waterproof effect on the structure, after supplying the washing water to the first metal pipe 10, as in the above-described process, the valve members 40 here When the waterproofing liquid is supplied through one of the valve members, the waterproofing liquid is quickly affinity with the washing water filled in the void gap, and the waterproofing liquid is filled in the crack gap in the same order as described above.

In addition, if the waterproofing solution supplied as a crack becomes too thin and flows out through a hole or gap, it is easy to supply the waterproofing solution if it is added with an index material. It solidifies and fills up.

Thereafter, when the construction is completed, the metal pipe 10 fixed to the construction wall surface is cut, and when it is sealed with a sealing mortar, the work is completed.

Therefore, the crack filling repair apparatus and waterproof construction method of the structure according to the present invention, the washing water is first injected into the micro-gap of the crack generated according to the internal deformation of the structure and the pressure corresponding to the washing water injection to check the corresponding filling material By injecting, the filler can be quickly penetrated into the micro-gap, and the filler can be selectively mixed according to the characteristics of the gap of the construction site, so that the gap of the crack can be stably sealed. Therefore, it is effective for waterproofing and repairing rooftop slabs of natural caves or buildings.
