BACKGROUND OF THE INVENTION [0001] The present invention relates to a pipe fixing device used for accurately positioning and fixing a pipe in a sewer work for burying a sewer hype. It can be widely used for laying sewer pipes. 2. Description of the Related Art Conventionally, when a sewer pipe is buried, a pipe placed at the bottom of an excavated moat is measured and positioned by measuring the position and slope, and a ring, a holding pile, and the like are provided at the top and side of the pipe. The position was maintained by laying, pushing in, or bundling the inclusion. [0003] Since the burial of a sewer pipe is caused to flow naturally, which is different from the burial of a water pipe to which water pressure is applied, the sewer pipe to be laid in a sewer is required to have a construction accuracy of millimeters in position and slope. On the other hand, pipes have a bend before construction, and when they are placed in an excavated moat, they are bent by their own weight, so that the position and gradient are often out of order. For such bending or warping of the pipe, a ring is applied between the side of the pipe and the side wall of the moat, or the holding pile is driven into the ground and bound to the pipe with an iron wire or the like to forcibly bend. And took measures to prevent the deviation of the specified position. [0004] [Problems to be Solved by the Invention] Conventionally, there was no tool for positioning and fixing a sewer pipe arranged in a dug excavation, so that the position and slope of the pipe were accurately determined in accordance with the survey. However, the operation for maintaining the state was extremely inefficient. For example, after laying a pipe, a method of stacking a ring above or on the side of the pipe, driving a pile, and binding the pipe to the pipe has been used. Because the ring is stepped on with the foot, the position of the pipe that is correctly installed is incorrect, and when binding the pipe to the pile with an iron wire, the pipe is often deformed depending on how it is tightened. We often depended on construction. Therefore, at the time of the water inspection after the completion of the burial work, the normal line is disturbed or the pipe is distorted, and the repair work may be performed. [0005] [Means for solving the problem] In the present invention, the tube holding plate at one end is formed to have a cross section <shape to provide a non-slip on the inner surface side, and a rotating portion is provided at the top on the outer surface side. Connect the connection bolt part whose tip is screwed to the nut part of the length adjustment part having,
One end of a reverse-wound bolt portion, the other end of which is connected to a hinge, is screwed to a nut portion on the other end side of the length adjusting portion, and a support plate having a support bar protruding is connected via the hinge. It is a pipe fixing tool for constructing a sewer. [0006] [Operation] The present invention is used when only one side is fixed in a state where the pipe to be buried is fixed on one side, or when two pipes are used to fix the pipe from both sides. FIG. 5 shows a case where two of the present invention are used and the side circumference of the pipe is fixed from both sides. Hereinafter, the operation will be described with reference to FIG. The inner surfaces of the two pipe holding plates 1 are abutted against the side circumference of the pipe 11 placed on the foundation 13 in the excavated moat, and the length adjusting portions 3 are respectively attached to the Ip 11 and the moat. Fit between side walls 12. In this case, the non-slip 2 on the inner surface of the pipe holding plate 1 fixes the pipe 11 accurately. Further, since the reversely wound bolt portion 8 and the support plate 5 are connected via the hinge 9, the moat side wall 12 can be easily fitted even if it is not a smooth surface, and the protruding support rod 10 is inserted into the ground. This stabilizes the fixture body and facilitates the work. [0007] Thereafter, the length adjusting portion 3 is appropriately rotated by the rotating portions 6 of the length adjusting portions 3 on both sides, and the screwing positions of the reverse winding bolt portion 8 and the connecting bolt portion 4 are moved, so that both sides are moved. By extending or shortening the pipe, the pipe can be fixed accurately and firmly at a predetermined position where the position and the gradient are determined. [Embodiment] An embodiment will be described with reference to FIGS. 1, 2, 3 and 4. The pipe holding plate 1 having a cross section <shape has a plurality of slip stoppers 2 on the inner surface side, and connects one end of a connecting bolt 4 to the top on the outer surface side, and adjusts the other end of the connecting bolt portion 4 to a length. The nut 3 at one end of the part 3 is screwed. One end of a reverse-wound bolt portion 8, the other end of which is connected to a hinge 9, is screwed into a nut portion 7 ′ on the other end side of both length adjusting portions 3, and a support rod 10 is connected via the hinge 9. The projecting support plates 5 are connected to each other. At the center of the length adjusting portion 3, a connecting bolt portion 4 which is screwed into the nut portions 7 and 7 'at both ends by rotating.
In order to move the screwing position of the reverse winding bolt portion 8 to appropriately extend or shorten the entire length, a rotation having a recess or a hole (not shown) having a quadrangular cross section as shown in FIG. Constituting part 6. [0009] [Effects of the Invention] The present invention is intended to securely fix a position and a gradient by firmly fixing a pipe to be laid in a culvert work for burying a sewer pipe, and It is very effective in the construction of sewerage because it can deal with the correction of bending and warping.
In addition, in the present invention, the pipe is fixed, buried with the backfill material to the top of the pipe, and then removed, so that there is no foreign matter other than the backfill material around the pipe. Therefore, a uniform earth pressure is applied, and even after the backfilling is completed, the accurate position and slope at the time of burying can be maintained for the force applied from the ground surface by a vehicle or the like.
