Problems solved by technology

However, for the respective foundations in different regions, the geological conditions are often different, and the load requirements of the superstructure are also different. In addition, even within the scope of a construction site, the soil conditions of different projects are often different. It is different, which determines that in different regions, for different soil construction projects, different weights or diameters are required for the same pile-forming equipment for ramming, expanding and compacting the filling material of composite foundation piles. However, for the current pile-forming construction equipment, the range of lifting capacity of its lifting mechanism is limited, and

Abstract

Pile-forming construction equipment for ramming and compacting the filler of a composite foundation pile comprises a slewing platform (7), a mast (4) arranged on the slewing platform (7) and a hoisting mechanism, wherein the hoisting mechanism comprises a windlass (8) and a steel wire rope (3); one end of the steel wire rope is wound on the windlass to be driven; the other end of the steel wire rope hangs a heavy hammer for ramming and compacting the filler after passing through pulleys on the mast; and the windlass is a hydraulic type windlass according the mode that different heavy hammers corresponding to the bearing capacities of different composite foundations can be hung according to the construction of different soil textures so as to expand the application range of construction of composite foundation piles.

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...
