Method for realizing automatic over-pressure piling and compaction in holes

Abstract

The invention relates to a method for realizing automatic over-pressure piling and compaction in holes, which comprises the following steps: making an automatic unhooking and hooking device controlled by a crane fall off and pierce a bell mouth on the upper part of an over-pressure counter weight by utilizing self weight; under the action of forces of vertical and transverse counter-force points, making the unhooking and hooking device hook hooking holes of a weight body; hoisting the counter weight to designed elevation in the air by using the crane and then making the unhooking and hooking device unhook the hooking holes of the weight body, so that the freely-falling weight body pierces a foundation hole; making the unhooking and hooking device fall off to drill and hook the weight body; repeatedly performing the steps of the hoisting of the weight body, the unhooking of the weight body, the falling-off of the weight body, the automatic weight body hooking of the unhooking and hooking device and the hoisting of the weight body, and then filling a filler with high design requirements into the foundation hole; and then repeatedly performing the steps and finally obtaining the deep foundation of a composite foundation, specific pile foundations and pre-expanded ecological pile bodies with high bearing capacity so as to fulfill the aims of processing the foundation into piles and the composite foundation and eliminating garbage contaminants.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and relates to a pile foundation suitable for foundation engineering, a composite foundation and a construction technology for eliminating garbage pollution. Background technique [0002] The previous "pile foundation" foundation treatment methods include immersed tube method, 800tm ultra-strong compaction method, and lime-soil compaction method, etc. These methods have the disadvantages of small construction energy, small pile diameter, and small friction resistance, etc. The length is designed to be about 30-60m, which not only causes a lot of waste, but more importantly, the pile foundation is difficult to reach the design standard. Although reinforced concrete piles are currently used in the field of building construction, a little carelessness in design and use will often cause quality accidents such as cracks in the building structure and even major accidents such as the co...

Problems solved by technology

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 just landfilling 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, and these will be infinitely disastrous in the long years to come and people and their descendants
