Embodiment Construction

[0062] Specific implementation examples

[0063] Plain soil compaction pile equipment mainly includes: hole-forming equipment, tamping equipment and supporting equipment. Hole-forming equipment consists of immersed tubes, movable pile tips, bladders, and fixed barrels; ramming equipment consists of rammers, rammers, rammer corner plates, and control rods; supporting equipment consists of support frames, support rods, and mobile vehicles. composition. The main steps of the construction method are: on-site installation of hole-forming equipment, supporting equipment, and compacting equipment; sinking with a hammer sinking tube compaction pile machine according to the designed pile length; water injection and humidification during the hole-forming process; pulling out the pipe after hole-forming , Pull out the pipe for the second punching, use tamping equipment to tamp down the fallen soil, and then the filler is tamped layer by layer to complete the construction.

Abstract

The invention relates to a plain soil compaction pile device. The device mainly comprises a hole forming device, a ramming and expanding device and a supporting device, wherein the hole forming deviceis composed of an immersed tube, a movable type pile tip, a bag and a fixed cylinder; the ramming-expanding device is composed of a rammer, a ramming machine, a rammer corner plate and a regulating rod; and the supporting device is composed of a supporting frame, a supporting rod and a moving vehicle. The construction method of the plain soil compaction pile device comprises the following steps that the hole forming device, the ramming-expanding device and the supporting device are installed on site, a rammer immersed tube compaction pile machine is adopted for hole immersing according to a designed pile length, water injection and humidifying are carried out in the hole forming process, the immersed tube is drawn out after the hole forming process is completed, secondary punching is carried out after the immersed tube is drawn out, falling-back soil is rammed by using the ramming-expanding device, and then filing materials are rammed layer by layer so as to complete the construction.The construction method is used so that soil between piles can be extruded and compacted to form a composite foundation. The plain soil compaction pile device and the construction method have the advantages that the construction machinery is saved, the construction cost is reduced, the working efficiency is improved, the noise and the muddy water pollution are reduced, muck is consumed and the environment is maintained.

Description

technical field [0001] The invention relates to a ground treatment method in a loess area, in particular to plain soil compaction pile equipment, a construction method and a pile forming method. It belongs to the field of foundation treatment and is suitable for deep soft foundation treatment of roads, dams, housing construction and other projects. Background technique [0002] my country has a vast territory, complex geological conditions and large differences between regions, and there are many types of loess foundations with wide distribution; especially in Northwest Gansu, there are deep loess foundations. With the further development of my country's economy, the requirements for the loess area in Northwest China will inevitably increase, which will also make the number and scale of loess projects in Northwest China continue to expand. It is an urgent problem to be solved in the field of geotechnical engineering to seek ultra-deep loess foundation treatment methods with...
