[0002] Pipeline pre-embedding is the process of burying pipelines in advance for subsequent structural and process construction in construction projects. There are few pipelines in building structures that are open. In general cast-in-place structures, when tying steel bars, the wire pipes are fixed to the formwork and steel bars. After pouring concrete, the pipes are in the structural components. Pre-embedding, as the name suggests, means burying before pouring concrete to facilitate subsequent threading.
[0003] Traditional concrete pre-buried pipe positioning devices usually use wooden boards, extruded boards, etc. as temporary covers for positioning. However, extruded boards cannot be reused as covers, and long-term use will cause a large amount of foam waste. Although wooden boards can be reused as covers for positioning, they are inconvenient to use. The position of the pre-buried pipe is easy to deviate, and the position of the pre-buried pipe may not match the drawing or the pre-buried pipe may be tilted, resulting in the reserved holes between the upper and lower floors not being in the same position, and the subsequent pipelines cannot be arranged reasonably. Utility Model Content

Two groups of handles 6 are provided, and the two groups of handles 6 are symmetrically distributed on the surface of the cover plate 3, which is convenient for loading and unloading the cover plate 3 and the pipeline. The surface of the handle 6 is provided with an anti-slip pattern, which can increase the friction with the hand;
[0023] A balancing device is provided on the surface of the base 4, and the balancing device includes a limit plate 8, a baffle 9, a balancing block 10, a PVC transparent plate 11, a connecting block 13 and a spring 14. Four groups of baffles 9 are welded on the surface of the base 4, and the baffles 9 are of an L-shaped structure, and a cross groove is formed between the four groups of baffles 9. The balancing block 10 is a hollow structure, and a PVC transparent plate 11 is installed on the surface of the balancing block 10. The surface of the PVC transparent plate 11 is bonded with scale lines. Whether the pipeline is tilted can be judged by observing whether the liquid inside the balancing block 10 is balanced with the scale lines. A water inlet is provided on the surface of the balancing block 10, and the water inlet is an external thread structure. The outer wall of the water inlet is threadedly connected with a fixing cover 7, and the fixing cover 7 is an internal thread structure. The threaded connection increases the airtightness inside the balancing block 10 to prevent the liquid inside the balancing block 10 from leaking;
[0024] A connecting groove 15 is provided inside the balancing block 10, and the balancing block 10 is placed inside the cross groove. One end of the spring 14 is welded to the surface of the base 4, and the other end of the spring 14 is welded to the bottom of the connecting block 13. The outer walls of the connecting block 13 and the spring 14 pass through the inside of the connecting groove 15. A limiting plate 8 is welded on the top of the connecting block 13. The limiting plate 8 is a round pancake structure, and a pull ring 12 is welded on the surface of the limiting plate 8 to facilitate the deformation of the spring 14 and adjust the angle of the balancing block 10. The cross section of the connecting groove 15 is circular, and the diameter of the limiting plate 8 is 1 cm to 1.5 cm larger than the diameter of the cross section of the connecting groove 15.

Place the cover plate 3 at the cross section of the pipe to be embedded through the handle 6, so that the guide column 2 is tangent to the inner wall of the pipe, and observe the water level line inside the balance block 10 and the PVC pipe. Check whether the scale lines on the surface of the transparent plate 11 are aligned. When aligned, they are in a horizontal position. At this time, concrete can be poured at the embedded position. The limit plate 8 connecting block 13 is pulled by the pull ring 12, thereby driving the spring 14 to deform and lengthen. The balancing block 10 placed on the surface of the base 4 is picked up, rotated 90 degrees and engaged with the inner wall of the cross groove. The pull ring 12 is released, and the spring 14 is reset, driving the limit plate 8 to fix the balancing block 10 on the surface of the base 4, so that the balancing block 10 is perpendicular to the surface of the cover plate 3. At this time, the horizontal pipe can be embedded.
