Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing apparatus for lining repair of underground structures,

The present invention relates to a reinforcing apparatus for repairing a lining of an underground structure, and more particularly, to a reinforcing apparatus for repairing lining of an underground structure, And more particularly, to a reinforcing device for repairing and repairing a lining of an underground structure capable of repairing and reinforcing pipes, which are aged due to excavation, in a robust, safe and efficient manner.

Generally, non-excavation repair method is a method of repairing an abnormal part when underground structures such as pipelines buried in the underground are deteriorated or partially damaged, seams are broken, steps are created, .

Such a repair method includes a full repair method in which a synthetic pipe is totally inserted in an abnormal region, an adhesive resin solution is applied to the glass fiber only by using an adhesive resin solution and glass fiber, and then hardened A reinforcing ring method in which a non-excavating repairing member made of stainless steel configured to be wound in a cylindrical shape is installed in close contact with a pipeline, and the like.

Among the above methods, the lining method can relatively easily break the cracks and cracks of pipelines which cause leakage compared with other construction methods, and has a merit that the inside of the piping is smooth and minimizes the obstacle to the flow of sewage, Has come.

However, in the case of such a lining method, since the lining material coated on the inner wall of the pipeline is liquid or soft and has to be rigid so as not to fall off until it is hardened, it is structurally very weak and various problems have arisen due to this, The process of covering the inner wall of the pipeline is complicated and complicated. Therefore, expensive equipment is used, the construction time is long, and even when the lining material is coated, the structural rigidity is still weak, The coated lining material was always exposed to the risk of being easily separated from the inner wall of the pipe even after the lining material was cured.

Therefore, in order to solve the problems caused by the lining method, recently, there has been proposed an improved lining for repairing an abnormal part by using a stainless steel plate, which is constructed by winding a cylinder in the inside of the repairing material, A repair method is being used.

In the case of the improved lining partial repair method, it is possible to cover the lining material thinly compared to the existing lining method, the work process is comparatively simple, and the structural rigidity can be ensured. Thus, the problems caused by the lining method It was able to solve a considerable part of it.

However, the stainless steel sheet used in the above-described improved lining partial repair method had to be provided with a high strength because it was required to support all the loads without receiving the help of the lining material having no self-supporting force.

In particular, when repairing medium- and large-sized pipelines such as an auxiliary pipeline, it is necessary to provide a stainless steel plate having a higher strength.

Therefore, due to the stainless steel sheet having a high strength, there is another problem that the work can not be performed in a part where the part of the channel is bent, the section of the stepped connection and the shape of the inner wall are irregular or the work performance of good quality can not be expected .

In order to solve these problems, there is also a Korean Patent Registration No. 10-1031904, but it is difficult to install continuously in the longitudinal direction, and it takes a long time to install, which not only increases the cost but also can not control the inner diameter, There was a difficult problem.

The main object of the present invention is to provide a method and apparatus for quickly repairing and reinforcing damaged parts such as deterioration, cracks, breakage, joints and connection steps of an underground structure such as a pipeline, And a reinforcing device for repairing and lining the underground structure.

It is another object of the present invention to provide an underground structure for preventing a hanging phenomenon in a longitudinal direction of an underground structure to prevent a hanging due to a flow and visually identifying the inside of the underground structure, And a reinforcement device for lining repair.

In order to achieve the above object, a reinforcing apparatus for lining maintenance of an underground structure according to the present invention includes a plurality of longitudinally extending reinforcing devices on the inner surface of an underground structure, and a plurality of connecting press- And a finishing plate which is provided between the supporting frames to form an engaging piece which is inserted in the longitudinal direction and inserted into the engaging groove and blocks the underground structure, The coupling protrusions corresponding to each other are formed in the lengthwise direction, respectively, so that the coupling protrusions can maintain a rigid coupling state while accepting the error.

Therefore, the reinforcing device for repairing the lining of the underground structure of the present invention is constructed such that the anchor is press-fitted into the perforation hole and then the support frame is installed in the longitudinal direction, And a finishing plate is provided between the supporting frame and the supporting frame to block the surface of the underground structure. The engaging piece of the finishing plate is inserted into the engaging groove of the supporting frame to engage with the engaging groove of the supporting frame, The support frame can be firmly coupled by the coupling protrusion formed in the coupling groove of the support frame and the coupling protrusion formed in the longitudinal direction of the coupling groove of the support frame. Even if an error occurs in the gap between the support frame and the support frame, To be able to do, the structure of the aging, cracks, breakage, joints spread It can repair and reinforce the damaged part such as the connection part step as well as it can repair and reinforce the deteriorated and ducted pipeline firmly, safely and efficiently. It is possible to identify and cure the concrete, the cement mortar or the lining material accurately by injecting it.
