Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sewer pipe positioning device used at a site where a sewer pipe is laid.

[0002]

[Prior art]

 The laying of sewer pipes is carried out by successively adding unit pipes in the excavation trench provided at the site.However, since it is required that the entire sewer pipes be formed in a straight line with a constant gradient, It is necessary to accurately determine the position of the tip of each unit pipe to be added. For this reason, the conventional practice has been to place a mache under the pipe in order to adjust the height of the pipe, or to insert a wedge between the pipe and the macula to prevent the pipe from slipping. Precise positioning of the pipes was not easy, and if the macula was left until after the construction, it was pressed by the earth pressure and the macula, and in the case of PVC pipes, the pipes were deformed.

[0003]

[Problems to be solved by the invention]

 An object of the present invention is to provide a device that can accurately and easily position a pipe when laying a sewer pipe.

[0004]

[Means for Solving the Problems]

 The means adopted by this invention is to provide a sewer pipe positioning device consisting of the following members. 1. A support member (6) provided horizontally, horizontally and fixedly in a digging trench in which a sewer pipe is laid. 2. A horizontal member (10) supported by the support member so as to freely move and fix horizontally. 3. A vertical member (14) provided so as to be able to move horizontally following the horizontal member and freely move and fix itself vertically. 4. A sewer pipe holding clamp (17) fixed to the lower end of the vertical member. The method of fixing the support member (6) in the excavation trench and the manner of attaching the horizontal member (10) and the vertical member (14) supported by the support member will be described in the next section, "Embodiments of the invention."

[0005]

[Embodiment of the invention]

 A support tube is used as the support member (6). This support pipe (6) is laterally inserted between the sheet piles (2) and (3) provided in the excavation groove (1) where the sewer pipe is laid through the tension mechanisms (4) and (5). Horizontal and fixed. The tensioning mechanisms (4) and (5) include, for example, bolts (4a) and (5a) inserted through the support tube (6) from each tube end and a nut (4b) screwed into the bolt outside the support tube. (5b). One end of the support pipe (6) is fixed to the sheet pile (3) via the bolt (5a) and the nut (5b), and when the nut (4b) in contact with the other end is turned, the bolt (4a) Moves right in the figure, the head of the bolt presses the sheet pile (2), and the tension fixing of the support pipe (6) is completed.

[0006] A horizontal pipe is used as the horizontal member (10). The horizontal pipe (10) is movably fitted to a horizontal threaded rod (9) connected in parallel to the support pipe (6) via connecting members (7) and (8). Since the horizontal thread rod (9) is parallel to the support pipe (6), if the support pipe (6) is provided horizontally in the digging groove, the movement of the horizontal pipe (10) becomes horizontal. The nuts (11) and (12) for fixing the horizontal pipe are screwed into the horizontal screw rod (9) outside the both ends of the horizontal pipe (10). By abutting these nuts on the respective pipe ends of the horizontal pipe (10), the horizontally movable horizontal pipe can be fixed at an arbitrary position.

[0007] A vertical threaded rod is used as the vertical member (14). The vertical threaded rod (14) is movably provided through a vertical pipe (13) fixed at a right angle to the horizontal pipe (10). This movement is vertical if the support pipe (6) is provided horizontally as described above. Further, the vertical screw rod (14) can move horizontally following the horizontal pipe (10) together with the vertical pipe (13). Threaded rod fixing nuts (15) and (16) are screwed into the vertical threaded rod (14) outside the both ends of the vertical pipe (13). By contacting these nuts with the ends of the vertical pipe (13), the vertically movable vertical screw rod can be fixed at any position.

[0008] A sewer pipe holding clamp (17) is fixed to the lower end of the vertical threaded rod (14). Since a conventional clamp may be applied to this clamp, the description and illustration of the gripping mechanism will be omitted.

When this device is used, the supporting pipe (6) is fixed in the above-mentioned manner in the digging groove, and the horizontal pipe (10) is placed so that the vertical threaded rod (14) is in a proper line of sight of the sewer pipe. ) And fix it by moving the vertical threaded bar (14) vertically so that the clamp (17) can grip the sewer pipe at the appropriate height. Fig. 2 shows the sequence of laying sewer pipes. By using the device (21) of the present invention, the tip of the laid sewer pipe (22) is grasped at an appropriate position, and the pipes are connected to each other. 23) Cover and fix the sewer pipe. The device (21) of the present invention is removed and moved, and the same operation is performed on the sewer pipe (24) to be laid next, and the process proceeds sequentially.

[0010]

[Effect of the invention]

 Since the present invention is configured as described above, the clamp for sewer pipe gripping can be very easily installed simply by mounting the support member in the excavation groove, moving and fixing the horizontal member, and moving and fixing the vertical member. Can be accurately positioned. This has made it possible to lay sewer pipes at appropriate locations easily without using the conventional methods such as macula, which has disadvantages.
