Description

Technical Field

[0001] The utility model patent relates to the technical field of reverse construction method steel pipe column positioning construction equipment, specifically, to a bracket hopper for self-unloading filler. Background Art

[0002] In the reverse first insertion method, the bottom bored pile is generally combined with the upper steel pipe column. When the steel pipe column is positioned, the steel pipe column is first inserted into the 4m position of the top steel cage of the bored pile and positioned, and then the bottom pile body concrete is poured to the designed elevation position; before pouring the concrete in the steel pipe column, in order to avoid the disturbance of the steel pipe column during the pouring of the concrete in the column and affect the verticality of the steel pipe column, it is necessary to evenly backfill the gap between the steel pipe column and the wall of the drilled hole to ensure the stability of the steel pipe column during the subsequent construction process.

[0003] Usually, during the reverse construction, a universal platform is used to position the steel pipe column, and a double-tube backfill bucket is set up on the side of the tool column to symmetrically guide the material into the gap between the steel pipe column and the borehole wall for uniform backfill. Generally, crushed stone, sand or construction waste is used as backfill. However, when the reverse construction uses a full-casing full-rotation drilling rig to position the steel pipe column, it is not suitable for backfilling with a double-tube backfill bucket due to factors such as the size and height of the full-casing full-rotation drilling rig. Direct backfilling with an excavator is difficult, and manual backfilling is inefficient. Utility Model Content

[0024] Reference Figure 1-3 As shown, it is a preferred embodiment provided by the utility model.

[0025] The bracket 7 hopper of the self-unloading filler comprises a universal platform 1, a borehole 6, a steel pipe column 4, a full-casing full-rotation drilling rig 2 and a material discharge guide trough 5. The universal platform 1 is arranged directly above the borehole 6. The full-casing full-rotation drilling rig 2 is arranged directly above the universal platform 1. The steel pipe column 4 is inserted into the borehole 6. The top of the steel pipe column 4 extends upward through the universal platform 1 and the full-casing full-rotation drilling rig 2. Four hydraulic columns 3 are distributed in a matrix along the full-casing full-rotation drilling rig 2. A hopper body is arranged on both sides of the full-casing full-rotation drilling rig 2. The hopper body is composed of a material discharge guide trough 5 welded to the bracket 7. The material discharge guide trough 5 extends to the gap between two adjacent hydraulic columns 3.

[0026] By arranging two hoppers symmetrically in the gap between the hydraulic columns 3 of the full-casing full-rotation drilling rig 2, and extending the feeding guide trough 5 to the position of the full-casing full-rotation drilling rig 2 close to the steel pipe column 4, crushed stone is poured into the two feeding guide troughs 5 in turn by an excavator, so that the weight of the crushed stone can be fully utilized, and the crushed stone is introduced into the gap between the hole wall of the borehole 6 and the steel pipe column 4 along the inclined surface of the feeding guide trough 5 for backfilling, thereby achieving the purpose of increasing the backfilling speed and improving the backfilling efficiency.

[0027] Specifically, in this embodiment, the material discharge guide 5 is composed of a side plate 9, a bottom plate and a supporting steel bar 8 welded together. The side plate 9 and the bottom plate are both 15 mm thick steel plates. The side plate 9 is two right-angled trapezoidal plates with an upper bottom of 1710 mm, a lower bottom of 2100 mm, and a height of 400 mm. The bottom plate is a square plate of 2240 mm × 2380 mm.

[0028] Since the length of the bottom plate is greater than that of the side plate 9, the bottom plate of the feed guide trough 5 can be extended to a position close to the steel pipe column 4 in the full casing and full rotation drilling rig 2, so that the backfill material can be directly introduced into the gap between the steel pipe column 4 and the wall of the borehole 6 along the bottom plate of the feed guide trough 5.

[0029] Specifically, in this embodiment, the support steel bar 8 is a threaded steel bar with a diameter of 36 mm, and both ends of the support steel bar 8 are welded to the middle of the two side plates 9.

[0030] The two side plates 9 can be supported by the provided supporting steel bars 8 to prevent the side plates 9 from being deformed due to stress, thereby ensuring the service life and structural strength of the device.

[0031] Specifically, in this embodiment, the distance between the two hydraulic columns 3 on the side of the full-casing full-rotation drilling rig 2 is greater than the width of the material discharge guide groove 5 .

[0032] Since the width of the feed guide groove 5 is smaller than the spacing between the two hydraulic columns 3, the feed guide groove 5 can be conveniently extended through the two hydraulic columns 3 into the position close to the steel pipe column 4 in the full casing and full rotation drilling rig 2, so that the backfill material can be directly introduced into the gap between the steel pipe column 4 and the wall of the borehole 6 along the bottom plate of the feed guide groove 5.

[0033] Specifically, in this embodiment, the vertical angle of the material discharge guide groove 5 is 60°.

[0034] Since the vertical angle of the material discharge guide groove 5 is 60°, the deadweight of the crushed stone can be fully utilized, so that the crushed stone is introduced into the gap between the hole wall of the borehole 6 and the steel pipe column 4 along the inclined surface of the material discharge guide groove 5 for backfilling.

[0035] Specifically, in this embodiment, the bracket 7 is composed of legs 10, a crossbeam 12 and a diagonal brace 11 that are welded together.

[0036] The legs 10 can provide a certain support to the material discharge guide 5, and the cross beam 12 and the diagonal brace 11 cooperate with each other, thereby improving the overall support capacity and structural strength of the bracket 7 and ensuring the stability of the device.

[0037] Specifically, in this embodiment, the leg 10 is 10# channel steel, and the specification of the leg 10 is 100×48×5.3 mm.

[0038] Specifically, in this embodiment, the cross beam 12 and the diagonal brace 11 are both threaded steel bars with a diameter of 36 mm, which can ensure the structural strength and supporting capacity of the hopper body.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
