Embodiment 1

[0024] Embodiment 1: a kind of automatic packing compaction equipment, see Figure 1-3 , including a structural platform 1, a compacting component 2, a feeding mechanism 4, and an electric control device.

[0025] see Figure 1-3 , A stand 11 is provided on the structural platform 1 . In this embodiment, the vertical frame 11 adopts a folding structure, and a support seat 111 is provided on the upper surface of the structural platform 1, and an independent frame 112 is hinged on the support seat 111. In this embodiment, the support seat 111 is a gantry frame, Independent frame 112 can be bar-shaped, well-tac-toe frame, inverted L-shaped frame, T-shaped frame, and the telescopic rod 12 that is used to receive independent frame 112 and is used to support the independent frame 112 after folding is also installed on structure platform 1. Support 13, the height of support seat 111 and support 13 is set to: when stand 11 is folded and when supported by support seat 111 and support...

Embodiment 2

[0039] Embodiment 2: A construction method for foundation treatment of compacted piles, comprising the following steps: setting the automatic packing and compacting equipment in Embodiment 1 next to the compacted pile foundation hole, and coordinating the winch 31 and the power unit 42 through the controller, so as to Make the quantity of filling in the hole of the compacted pile foundation by the feeding mechanism 4 linked with the hammering frequency of the compacting hammer 21 . The optimal value of the linkage is determined by those skilled in the art on the basis of common knowledge in the art and combined with limited experiments. In this way, the problem of low tamping efficiency caused by the tamping hammer being unable to effectively tamp the filler or too little filler can be avoided.

[0040] After using the controller to link the feeding mechanism and the hoist 31, the hammering frequency and the amount of filler are linked together. The automatic filler compaction...

Abstract

The invention discloses automatic filling and compacting equipment. The automatic filling and compacting equipment comprises a structure platform, a compacting assembly, a feeding mechanism and an electric control device, a vertical frame is arranged on the structure platform, the compacting assembly comprises a compacting hammer and a protection casing outside the compacting hammer; and the automatic filling and compacting equipment is characterized in that the feeding mechanism comprises a power unit with a speed change function, the feeding mechanism is arranged at a corresponding positionon the structure platform so as to enable materials discharged from a discharge port of the feeding mechanism to enter a compaction pile hole, and the electric control device is provided with a controller used for coordinating a first winch and the power unit so as to enable the quantity of the materials filled into the compaction pile hole by the feeding mechanism to be linked with the hammeringfrequency of the compacting hammer. The construction method for the compaction pile foundation treatment adopts the automatic filling and compacting equipment so as to carry out compaction pile construction. According to the automatic filling and compacting equipment, filling and compacting can be sufficient and uniform, and the produced compaction pile is stable and excellent in quality.

Description

technical field [0001] The invention relates to the technical field of foundation treatment in civil engineering, in particular to an automatic packing tamping equipment and a construction method for foundation treatment of compaction piles. Background technique [0002] Compaction piles are generally used to deal with poor foundations such as collapsible loess, backfill and liquefied soil layers. First, make compaction pile holes, which can be directly rammed and compacted by the underground soil layer with a rammer The hole formed can also be a long spiral lead hole, and the piles after fillers such as throwing plain soil, lime soil, sandstone, steel slag, dry hard concrete or other hard materials into the hole are compacted. The compaction pile belongs to a kind of lateral compaction, which can achieve the required density index after densification treatment, and improve the bearing capacity, reduce the compressibility, and the treated foundation is uniform, the bearing c...
