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...

Embodiment Construction

[0030] Referring to the accompanying drawings, the mechanism of the construction method of the present invention is to design a slenderness ratio λ=2~30 and a hammer tip inclination of 5°~90° according to the characteristics of the foundation soil, the site materials and the design needs of the foundation. The heavy hammer body 5 utilizes the overpressure strong kinetic energy E=3×10 per unit area produced by the hammer body 5 4 ~9.8×10 7 KN·m / m 2 Squeeze and tamp the foundation soil and the soil between piles by using the mechanism of punching, smashing, squeezing, pressing and splitting in three-dimensional space ( figure 1 ). Not only can it "automatically" punch holes from top to bottom (or bottom to top) according to different soil structures, it can create a "elastic body" (with P-S rebound value), high bearing capacity, and infinite stiffness value of 300. ~4000kPa deep foundation or elastic composite foundation, and according to the needs of geological structure and...

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...
