Waterpower self-excited oscillation jet flow vibratory pile sinking device and pile sinking technology

Abstract

The invention relates to a waterpower self-excited oscillation jet flow vibratory pile sinking device and a pile sinking technology. A reinforced concrete pile body is a sheet pile, a square pile head and a hanging ring are arranged in the middle of the top of the reinforced concrete pile body, the reinforced concrete pile body is connected with a vibratory hammer part through a vibratory hammer connecting device, a jet flow pipe with a self-excited oscillation jet flow nozzle is arranged on the bottom of the sheet pile, the jet flow pipe is connected with a high pressure water pump group through a water pipe and rapid docking movable elbows, and the vibratory hammer part is connected with lifting equipment through an integrated lifting appliance. The waterpower self-excited oscillation jet flow vibratory pile sinking device and the pile sinking technology have the advantages that construction technologies of different strata can be resolved, construction efficiency can be improved greatly at the same time, construction quality is guaranteed, drawbacks and defects exist in the prior art are overcome or avoided, the problems of hard clay strata pile sinking speed and breakdown of underground obstacles are resolved, the purpose that undisturbed soil on two 2-meter-long sides of the bottom of the pile body in a pile sinking process is not damaged is achieved, the two sides of the pile body are filled with sand to enable disturbed soil on the two sides of the pile body to be replaced by silver sand, and fast consolidation is achieved.

Description

technical field [0001] The invention relates to a pile sinking device and a pile sinking process, in particular to a hydraulic self-excited oscillation jet vibration pile sinking device and a pile sinking process. Background technique [0002] At present, the traditional pile sinking technology of existing reinforced concrete prefabricated piles includes: hammering type pile sinking, static pressure type pile sinking, vibration type pile sinking, flushing assisted pile sinking, vibration method assisted pile sinking and other processes. Among them, the hammering type pile sinking process and the static pressure type pile sinking process are not related to the present invention, so no statement is made; the water jet pile sinking process cannot be consolidated in a short period of time due to the disturbance of the undisturbed soil on the side of the pile body during the pile sinking process by water; the above The pile sinking process is difficult to increase the pile entry ...

AI Technical Summary

Problems solved by technology

A hydraulic inserting plate and its use method, comprising: (A) lifting a reinforced concrete pile plate with a lifting device, lowering it into the ground through a waterway and a water distribution pipe in the form of hydraulic jetting, and moving the slide plate of another reinforced concrete pile plate from the existing Insert the notched hollow square steel slideway of the pile slab that is lowered into the stratum, and go down into the stratum, including (B) the overall connection between the slabs. Fill with cement slurry to form an inner chamber completely isolated from the outside of the board; (C) Put a grouting pipe into the hollow square steel in the inner chamber, fill the cement slurry from bottom to top, and the entire board The joint between them will form a reinforced concrete overall structure with sandwich steel plates; (D) the top bea
