The construction distribution structure comprises a clean water pipe, a water inlet pipe and a water outlet pipe, wherein the bottom of the clean water pipe extends into a pile foundation hole in rock soil; and the bottom pipe orifice of the clear water pipe is provided with an external expansion shunting adjusting assembly for shunting and external expansion adjustment of clear water injection. Clear water injected into the pile foundation hole by the clear water pipe is distributed and expanded outwards on the water distribution plate with the water distribution holes instead of being concentrated at one position, so that slag stones at the opening of the clear water pipe cannot be pushed to the side edge of the bottom of the pile foundation hole to be accumulated, no slag stones are mixed with concrete during later pouring, and the problem that the slag stones cannot be accumulated during later pouring with the concrete is solved. And a slag rock pile located on the side edge of the bottom of the pile foundation hole cannot be evenly and effectively mixed with concrete.

Description

Technical Field

[0001] The utility model relates to a construction distribution structure for cleaning sediment in a pile foundation hole, belonging to the technical field of pile hole construction. Background Art

[0002] After the pile foundation hole construction is completed, the sediment needs to be injected with clean water to wash out the mud and discharge it. The washed sediment is retained at the bottom of the pile foundation hole for subsequent pouring with concrete (see Chinese Patent Publication No. CN115369877A).

[0003] When clean water is injected through the clean water pipe, the water injected at the pipe mouth of the clean water pipe in the pile foundation hole is concentrated in one place and expanded outward, causing the debris at the pipe mouth of the clean water pipe to be pushed to the bottom side of the pile foundation hole for accumulation, resulting in the debris pile at the bottom side of the pile foundation hole being unable to be evenly and effectively mixed with the concrete during the later pouring of concrete. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a construction distribution structure for cleaning the sediment in the pile foundation hole.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a construction distribution structure for cleaning sediment in pile foundation holes, comprising:

[0007] The bottom of the clean water pipe extends into the pile foundation hole in the rock soil;

[0008] The bottom pipe opening of the clean water pipe is provided with an outward expansion diversion regulating component for adjusting the outward expansion of clean water injection diversion.

[0009] The clean water pipe is a hose; the bottom pipe opening of the clean water pipe is provided with an outward expansion section.

[0010] The outward expansion flow diversion regulating component comprises a lower pressure plate, an upper pressure plate, a screw rod and a water diversion plate.

[0011] The lower pressure plate contacts the outward expansion section from above and presses it downward, and the upper pressure plate contacts the outward expansion section from below and presses it upward. A screw is installed between the lower pressure plate and the upper pressure plate, and nuts A and B are screwed on the screw to press the lower pressure plate and the upper pressure plate tightly. The outward expansion section is pressed between the lower pressure plate and the upper pressure plate.

[0012] The upper pressing plate is provided with a clamping protrusion, and the lower pressing plate is provided with a clamping groove corresponding to the clamping protrusion.

[0013] The water distribution plate is screwed onto the screw rod through nuts C and D. There is a space between the water distribution plate and the upper pressure plate. The water distribution plate is provided with a plurality of water distribution holes distributed at intervals, and the water distribution holes are downwardly conical.

[0014] The top surface of the water dividing plate is a wave-shaped surface.

[0015] The beneficial effect of the utility model is that the clean water injected into the pile foundation hole by the clean water pipe is diverted and expanded outward on the water diversion plate with the water diversion holes instead of being concentrated in one place, ensuring that the slag at the pipe mouth of the clean water pipe will not be pushed to the bottom side of the pile foundation hole for accumulation, and no slag pile will be mixed with the concrete when poured with the concrete in the later stage, thus solving the problem that the slag pile on the side of the bottom of the pile foundation hole cannot be evenly and effectively mixed with the concrete when pouring with the concrete in the later stage.

DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0021] like Figures 1 to 3 shown.

[0022] A construction distribution structure for cleaning sediment in pile foundation holes of the present application includes:

[0023] A pile foundation hole 2 is formed in rock and soil 1 by excavation, and a clean water pipe 3 is provided in the pile foundation hole 2 for injecting clean water, and the clean water pipe 3 is a hose. A sewage pump is also provided in the pile foundation hole 2, and the drainage port of the sewage pump is connected to the drainage pipe through a check valve, and the sewage containing mud in the pile foundation hole 2 is discharged through the drainage pipe. This is a prior art and will not be discussed here.

[0024] The bottom pipe mouth of the clean water pipe 3 in the pile foundation hole 2 has an outward expansion section 31 formed after cutting; the outward expansion section 31 is in contact with a lower pressure plate 4 pressing from top to bottom, and the outward expansion section 31 is in contact with an upper pressure plate 5 pressing from bottom to top. A screw 6 is installed between the lower pressure plate 4 and the upper pressure plate 5. Nuts A61 and B62 are screwed on the screw 6 to press the lower pressure plate 4 and the upper pressure plate 5. The outward expansion section 31 is pressed between the lower pressure plate 4 and the upper pressure plate 5.

[0025] The upper pressing plate 5 is provided with a clamping protrusion 51, and the lower pressing plate 4 is provided with a clamping groove (not shown in the figure) corresponding to the clamping protrusion 51. The upper pressing plate 5 is further clamped by the clamping protrusion 51 pressing the outward expansion section 31 and deforming it into the clamping groove of the lower pressing plate 4.

[0026] It also includes a water diversion plate 7 screwed on the screw rod 6 by nuts C63 and D64. There is a space between the water diversion plate 7 and the upper pressure plate 5. The water diversion plate 7 is provided with a plurality of water diversion holes 71 distributed at intervals. The water diversion holes 71 are downwardly conical. There are multiple water diversion plates 7, and the apertures of the water diversion holes 71 on different water diversion plates 7 are different. When clean water is introduced from the clean water pipe 3 and injected at the expansion section 31, it is diverted and discharged from the space between the water diversion plate 7 and the upper pressure plate 5 and the water diversion holes 71 to avoid concentrated expansion in one place. The water diversion plate 7 adjusts the space between the water diversion plate 7 and the upper pressure plate 5 by nuts C63 and D64 to adjust the diversion flow rate of the outward expansion when the clean water is injected. The top surface of the water diversion plate 7 is a wavy surface 72. The wavy surface 72 disturbs the water flow when the clean water is injected to avoid the water from concentrating and expanding in a single form.

[0027] The water diversion plate 7 with a space between it and the upper pressure plate 5 is provided with a water diversion hole 71 to divert and expand the water injected into the clean water pipe 3, so that the lower pressure plate 4, the upper pressure plate 5, the screw 6 and the water diversion plate 7 form an outward expansion diversion adjustment component at the bottom of the clean water pipe 3 to adjust the clean water injection, so that the clean water injected into the pile foundation hole 2 by the clean water pipe 3 is diverted and expanded on the water diversion plate 7 with the water diversion hole 71 instead of being concentrated in one place for expansion, ensuring that the slag at the mouth of the clean water pipe will not be pushed to the side of the bottom of the pile foundation hole for accumulation, and there will be no slag pile mixed with the concrete in the later pouring, which solves the problem that the slag pile on the side of the bottom of the pile foundation hole cannot be evenly and effectively mixed with the concrete when pouring with the concrete in the later stage.
