Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction and relates to a supporting tool for buried drainage pipes. Background Art
[0002] The construction methods of buried drainage pipes mainly include open cut method, pipe jacking method and shield method. Among them, the open cut method is mostly used in the field of building construction, also known as the trenching and pipe laying method, which is suitable for drainage pipes with medium and small diameters. During construction, the trench is excavated according to the alignment. After the bottom of the trench reaches the predetermined depth, the pipes are laid at the bottom of the trench. After the pipes are laid, the soil is backfilled. The backfill soil should be compacted to make the pipe body evenly stressed and reduce the settlement amount of the ground after backfilling. The problem is that the bottom of the buried drainage pipe is unevenly stressed and lacks support. After backfilling the soil, the local part of the drainage pipe may sink and deform. Especially when the length of the drainage pipe is short and the elevation difference at both ends is small, the deformed pipe will cause poor drainage, and in severe cases, the pipe may break or be damaged. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a supporting tool for buried drainage pipes. The purpose is to set a supporting component at the bottom of the pipe for the buried construction of drainage pipes with medium and small diameters, so as to prevent the drainage pipe from sinking, deforming or being damaged after backfilling the soil and improve the construction quality.
[0004] To achieve the above purpose, the utility model provides the following technical scheme: a supporting tool for buried drainage pipes, including an anchor rod and a hook. The lower end of the anchor rod is set as a spike part for inserting into the soil. The hook includes an arc part and a vertical part fixedly connected to one end of the arc part. The arc part corresponds to the cross-sectional contour of the drainage pipe and is used for lifting the bottom arc surface of the drainage pipe. The vertical part can be fixedly connected to the anchor rod.
[0005] As a further optimization, the anchor rod is a hollow steel pipe.
[0006] As a further optimization, the vertical part is welded to the anchor rod.
[0007] As a further optimization, the vertical part is detachably connected to the anchor rod.
[0008] As a further optimization, a threaded section is provided on the side wall of the top end of the anchor rod, and a limiting round table is fixedly arranged at the lower end of the threaded section. A sleeve is fixedly connected to the side wall of the top end of the vertical part for sleeving on the threaded section of the anchor rod. The lower end of the sleeve abuts against the limiting round table, and its upper end abuts against a nut screwed on the threaded section for the detachable connection of the vertical part and the anchor rod.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0015] For Embodiment 1, please refer to Figure 1-2 , the present utility model provides a technical solution: A buried drain pipe support tool, including an anchor rod 1 and a hook 2. The lower end of the anchor rod 1 is provided with a spike part 11 for inserting into the soil. The hook 2 includes an arc part 21 and a vertical part 22 fixedly connected to one end of the arc part 21. The arc part 21 corresponds to the cross-sectional contour of the drain pipe 3 for lifting the bottom arc surface of the drain pipe 3. The vertical part 22 can be fixedly connected to the anchor rod 1.
[0016] During use, first dig a groove. The initial state is that the anchor rod 1 and the hook 2 are welded together to form this tool. Multiple such tools are arranged at intervals along the pipeline laying position, and the interval distance is 1.5 meters to 3 meters. First, insert the anchor rod 1 into the soil, with the burial depth being about 1.2 to 1.5 meters and the upper end emerging length being 10 to 20 centimeters. Then lay the pipeline so that the bottom surface of the pipeline abuts against the upper end of the arc part 21. Then, tap the top of the anchor rod 1 one by one, and the hook 2 moves downward accordingly to adjust the depth of each pipeline support point until the slope and straightness of the pipeline are qualified. Then fill the groove 31 with soil, first fill the soil on both sides of the pipeline, and then compact layer by layer so that the pipeline and this tool are buried in the soil together.
[0017] Preferably, the anchor rod 1 is a hollow steel pipe, which has a large contact area with the soil and is firmly anchored.
[0018] The advantages of this embodiment are that the structure of this embodiment is simple, easy to manufacture, and low in cost. It is suitable for use during pipe laying at the construction site, and can lift and support the drain pipe 3, reducing deformation or damage after backfilling and improving the construction quality.
[0019] Embodiment 2, please refer to Figure 1-2 , based on Embodiment 1, the difference lies in the different usage methods.
[0020] During use, in the initial state, the anchor rod 1 is separated from the hook 2. First, arrange multiple anchor rods 1 at intervals on the side of the pipeline laying position and insert them into the soil; then hook the hook 2 on the bottom of the pipeline, adjust the slope of the pipeline according to the stiffness of the pipeline itself, and then weld the vertical part 22 of the hook 2 to the upper end of the anchor rod 1 one by one to complete the support and fixation. Finally, backfill the soil.
[0021] It can be seen that in this embodiment, adjustment is carried out first and then welding, and the amount of adjustment work is less than that in Embodiment 1. Another advantage is that the hook 2 can be equipped according to the thickness of the pipeline. Especially when the thickness of the pipeline changes, the matching hook 2 can be flexibly selected.
[0022] Embodiment 3, please refer to Figure 1-3 ; based on Embodiment 2, the difference lies in that the vertical part 22 is detachably connected to the anchor rod 1. An exemplary detachable connection method is that a threaded section 12 is provided on the side wall of the top end of the anchor rod 1, and a limiting frustum 13 is fixedly provided at the lower end of the threaded section 12; a sleeve 23 is fixedly connected to the side wall of the top end of the vertical part 22 for sleeving on the threaded section 12 of the anchor rod 1; the lower end of the sleeve 23 abuts against the limiting frustum 13, and its upper end abuts against a nut 24 screwed on the threaded section 12 for detachably connecting the vertical part 22 to the anchor rod 1.
[0023] During use, first insert multiple anchor rods 1 into the soil; then hook multiple hooks 2 on the bottom of the pipeline until the sleeve 23 is sleeved on the top of the anchor rod 1 and is supported by the limiting frustum 13, and the position of the hook 2 is fixed; then, adjust the insertion depth of each anchor rod 1 one by one until the slope and straightness of the pipeline are qualified, and then screw the nut 24 onto the threaded section 12 one by one. Then, a spirit level can be used for inspection. If an error is found, the nut 24 can be loosened for adjustment and then tightened until the inspection is qualified and the nut 24 is tightened to complete the connection and fixation of the hook 2 and the anchor rod 1. Finally, backfill the soil.
[0024] It can be understood that compared with Embodiment 2, this embodiment replaces welding with threaded connection, the connection operation is more convenient, and adjustment can be carried out after fixed connection, with higher adjustment accuracy and better construction quality.
[0025] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
