The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.
The invention will be described in detail below with reference to the drawings and embodiments.
A reinforced concrete pipeline repairing device is shown in figures 1 to 6 and comprises an inner connecting plate 1 and an outer connecting plate 2, wherein the inner connecting plate and the outer connecting plate are fixed through a connecting assembly 3, and a pouring cavity 4 is formed between the inner connecting plate and the outer connecting plate; the outer connecting plate is provided with a plurality of grouting holes 16 and a plurality of exhaust holes 17, wherein the grouting holes and the exhaust holes are generally respectively provided with 2-5. The grouting holes are arranged at intervals, the exhaust holes are also arranged at intervals, and proper distances are reserved between the exhaust holes and the grouting holes, so that excessive grout is prevented from flowing out while exhaust is guaranteed in the process of pouring the concrete 10.
The connecting assembly comprises a plurality of connecting pieces 5 which are arranged on the inner connecting plate (extend outwards), one end of each connecting piece, penetrating out of the outer connecting plate, is locked by the fixing piece 6, the specific number of the connecting pieces is not limited, and the connecting assembly can be used for forming connection between the inner connecting plate and the outer connecting plate and facilitating subsequent concrete pouring. The inner connecting plate comprises a plurality of split bodies, the split bodies are connected through a butt joint structure, after the split bodies are spliced, part of connecting pieces are pulled, the outer connecting plate is buckled at a damaged position, the connecting pieces correspondingly penetrate through connecting holes of the outer connecting plate, then a fixing piece is screwed at one end of the connecting pieces penetrating out of the outer connecting plate, the outer connecting plate and the inner connecting plate are clamped and fixed on the side wall 15 of the pipeline and are kept stable, then concrete is poured into a pouring cavity through a pouring opening, and after the concrete is solidified, the repairing work is finished.
By way of example, the connecting element is a screw or a steel strand, and the fixing element is a lock nut. One end of the connecting piece is fixed on the inner connecting plate, and the other end of the connecting piece extends outwards (namely extends towards one side of the outer connecting plate). It should be noted that when the connecting piece adopts a screw rod, the screw rod with a proper length can be selected according to the side wall thickness of the pipeline, and when the connecting piece adopts a steel strand, in order to pass through a via hole on the outer connecting plate, the steel strand can be reserved with a sufficient length, and after the outer connecting plate is installed and locked by a fixing piece, the steel strand of the exposed part can be cut off.
In an alternative embodiment, as shown in fig. 5, the internal connection plate includes an upper part 7 and a lower part 8, the docking structure includes a slot formed on the upper part (toward one end of the lower part), and an insertion part 9 matched with the slot is formed on the lower part (toward one end of the upper part). The specific structure of the clamping groove is not limited, and the technical personnel in the field can adopt the conventional technical design, as long as the upper and lower split bodies can be conveniently inserted. The split inner connecting plate can be more conveniently arranged in the pipeline 14, particularly, under the condition that the inner connecting plate is not convenient to be axially arranged in the pipeline, the split inner connecting plate can be directly arranged in the pipeline from the damaged part, the split butt joint of the split inner connecting plate can be realized on the outer side of the pipeline, and the operation is very convenient and efficient.
In an alternative embodiment, as shown in fig. 6, the inner connecting plate is provided with a plurality of auxiliary inner connecting pieces 11 on one side surface facing the outer connecting plate and on one side surface facing the inner connecting plate. The auxiliary inner connecting piece can be in a rod shape or a plate shape, for example, the auxiliary inner connecting piece can be made of steel bars or steel strands, when a cavity is poured between the inner connecting plate and the outer connecting plate, concrete can be more sufficiently combined with the outer connecting plate (and the auxiliary inner connecting piece on the outer connecting plate) and the inner connecting plate (and the auxiliary inner connecting piece on the inner connecting plate), stability is higher, reliability is better, and the same service life as a pipeline main body part can be achieved. In addition, can also correspond the grout hole position at outer fishplate bar inner wall and set up sleeve 13, carry out the part to the grout hole position and strengthen, avoid the grout hole part damaged, when being equipped with sleeve, owing to need not to consider to bear great concrete dead weight and pressure, outer fishplate bar thickness can be littleer, reduces the consumptive material, and after repairing, can not lead to the pipeline external diameter to have too big change, do not influence normal use or lay, the limitation is little.
In an alternative embodiment, the inner connecting plate is provided with a sealing gasket 12 near the periphery of a side surface of the outer connecting plate, that is, the sealing gasket is arranged around the outer edge part of the inner connecting plate, so that the sealing between the inner connecting plate and the side wall of the pipeline is effectively ensured, and concrete is prevented from falling into the pipeline when pouring. Because the sealing performance requirements of the poured concrete and the liquid are different, when the inner connecting plate is designed to be of a split structure, the sealing gaskets can be mutually butted only after the split bodies are spliced and fixed, and a good sealing structure can be formed. After the outer connecting plate is locked and fixed with the inner connecting plate, the sealing gasket can be better sealed, so that no concrete enters the pipeline in the pouring process, the cleaning is not needed after the pouring is finished, the working procedures are saved, and the operation is simplified. It should be noted that, even if the pipeline buried underground is repaired, the operation can be performed only by digging out local soil of the damaged part, so that time and labor are saved, and the construction cost is remarkably reduced. Moreover, when the pipeline is damaged and is inspected, a damaged point is found, the preparation work in the early stage of repair is actually finished, and the pipeline repair device is only required to be installed and fixed in the follow-up process and then poured, so that the operation efficiency is improved, and the construction period is saved.
The invention has simple structure, low cost and convenient construction and operation, when the pipeline repairing operation is carried out, the inner connecting plate is only needed to be placed in the pipeline and spliced, and then the outer connecting plate and the inner connecting plate are fixed, the casting cavity between the inner connecting plate and the outer connecting plate can be subjected to the casting of the retarded soil, and the cast retarded soil can not fall into the pipeline, and the cleaning of the interior of the pipeline is not needed after the casting is finished. Therefore, the pipeline repairing device provided by the invention can be used for repairing the pipeline, so that the construction efficiency can be effectively improved, the construction period can be shortened, and the construction cost can be reduced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
