Problems solved by technology
[0005] According to the above-mentioned scheme, the heavy hammers required in the construction existing in the past pile-forming construction equipment for ramming, expanding and compacting the filling materials of composite foundation piles, for example, heavy hammers in the range of 2 to 40 tons can be solved. , but the actual pile-forming construction equipment has insufficient lifting capacity, and the power consumption of the hoist of this construction equipment is large and the structure is unreasonable, so that the construction of large-diameter piles cannot be carried out. The contradiction between the construction of large-diameter piles can be used without replacing the hoist Under the circumstances, it is suitable to use large pile spacing and large-diameter composite foundation piles to meet the requirements of the foundation construction of the bearing capacity, and at the same time reduce the construction cost of composite foundation piles

Embodiment Construction
[0021] As an embodiment of the present invention, the pile-forming construction equipment for ramming, expanding and compacting the filling material of composite foundation piles includes a platform 7 on which a mast 4 is arranged; a traveling device 10 is arranged under the above-mentioned platform 7 There is running gear 10; hoisting mechanism, and this hoisting mechanism comprises hoisting machine 8 and traction rope 3, and one end of this traction rope 3 is wound on the hoisting machine 8 and drives, and the other end of this traction rope 3 is arranged on above-mentioned mast 4 tops through The pulley 2 and the traction rope 3 are suspended downward through the pulley 2. A heavy hammer 1 is used for impacting, expanding and compacting the filling material of the composite foundation pile. The heavy hammer 1 consists of a roughly columnar hammer body and a roughly hammer-tip hammer. Bottom structure, the hoist 8 mentioned above can improve the lifting capacity of the weight...

A pile forming construction device for rammering, expanding and compacting fillers of composite foundation piles comprises a platform (7) and a winch mechanism. A mast (4) is arranged on the platform (7), and the winch mechanism comprises a winch (8) and a dragging rope (3). One end of the rope is wound on the winch to drive the winch, and the other end of the rope passes through a pulley on the mast to be perpendicular to a heavy hammer for rammering, expanding and compacting the fillers. The winch is a hydraulic winch which is formed by using a composite foundation pile construction method capable of improving hoisting capacity of the heavy hammer and suitable for achieving bearing force requirements by enlarging pile gaps and the diameter of the composite foundation piles without replacing the winch.
Description
technical field [0001] The present invention relates to the field of civil engineering. Background technique [0002] At present, in the construction of composite foundation treatment, in order to improve the bearing capacity, the construction method of composite foundation piles is often used. For the above-mentioned construction, people often use the following pile-forming equipment for composite foundation piles for construction. The construction equipment uses a heavy hammer to impact, ram, expand and compact the filling material filled in the pile hole. In this piling construction equipment, the heavy hammer used to impact, ram, expand and compact the filling material filled in the pile hole is lifted to a certain height by means of a sliding winch, and then the steel wire rope is loosened to allow the heavy hammer to fall freely. Realize the impact ramming, expansion and compaction of the filling material filled in the pile hole. In this case, for some foundation and...
