Five in one pre-expansion ecological pile body processing foundation method

Abstract

The invention relates to a five-in-one pre-expanding ecological pile treating foundation method suitable for foundation, foundation collapse, gold ore dressing and construction application of environment-friendly field. The method comprises: after the foundation is drilled with holes, filling the holes, injecting hammer blocks into the holes, carrying out five-in-one power consolidation of vertically and transversely pre-expanding, extruding, transmitting and propelling by super-pressure kinetic energy through impacting, smashing, extruding, pressing and chopping; then filling the holes repeatedly and carrying out forced ramming and piling consolidation of vertically and transversely pre-expanding, extruding, transmitting and propelling for the super-pressure kinetic energy hammer blocks through impacting, smashing, extruding, pressing and chopping; and finally manufacturing a deep foundation of a composite foundation of a pre-expanding ecological pile with high bearing capacity, a specific pile foundation and the pre-expanding ecological pile. The method is advanced, has low construction cost, effectively solves problems of various thick difficult foundations, can eliminate pollution of pollutant to environment, and make human live on the foundation of firmness, safety and free pollution.

Description

technical field [0001] The content of the invention belongs to the technical field of construction engineering, and relates to a five-in-one pre-expansion ecological pile body treatment method for foundation, which is suitable for foundation foundation, foundation collapse and construction application in the field of environmental protection. Background technique [0002] At present, the commonly used foundation treatment methods in the field of foundation treatment engineering mainly include "rotary excavation pile method", "reinforced concrete prefabricated pile method", "dynamic compaction method", "CFG pile method", and "lime-soil compaction pile method". etc., in specific implementation, their usefulness is different, and effect also has nothing in common with each other, all has respective strengths and weaknesses each other. "Rotary-dug cast-in-place pile method" is a method of foundation treatment widely used at home and abroad, but this method is too heavy for mecha...

Problems solved by technology

The treatment method of this method is to use "kinetic energy" to compact the foundation "from top to bottom", improve its original soil performance, strengthen high density, and increase bearing capacity. Elevation" increases the weight of the hammer, so that the technology develops from 1000KN to 10000KN, but the effective depth of foundation treatment is less than 10 meters, and the bearing capacity is generally 200-300kpa. Since modern building design requires "high" bearing capacity, the treatment of foundation Depth is "deep", so this method is necessarily limited

Nowadays, whether at home or abroad, people usually use huge sums of money to build "garbage landfills" or "mountain landscaping". "Pits" and other methods of dealing with garbage are often only land-based burial of garbage, without any re-creation value of comprehensive utilization, especially without any consolidation treatment of harmful substances contained in it, which will still affect water sources and the atmosphere. Re-pollution, and with the development of urban construction, these garbage pollutants will be relocated again, which can only pollute the society many times without any contribution to re-creating value. These will cause unlimited harm in the long years to come. future generations
