High-pressure flushing device used in cooperation with pile pressing machine

Abstract

The invention discloses a high-pressure flushing device used in cooperation with a pile pressing machine. The high-pressure flushing device comprises a transverse pressing beam; an extension plate is fixedly connected to the side edge of the transverse pressing beam; a drilling machine is fixedly connected to the upper portion of the extension plate; a pressing sleeve and a middle drill rod which are driven by the output end of the drilling machine are connected to the lower portion of the extension plate; a water injection hole is formed in the side edge of the pressing sleeve; a water spraying probe is connected into the water injection hole in a sliding manner; a screwing-in mechanism used for moving of the water spraying probe is arranged in the pressing sleeve; a water conveying pipe is arranged in the pressing sleeve; the lower end of the water conveying pipe is fixedly connected with the end of the water spraying probe; a high-pressure water pump is fixedly connected to the upper portion of the extension plate; and the upper end of the water conveying pipe communicates with the high-pressure water pump. According to the high-pressure flushing device, the water spraying probe sprays water flow and divides the water flow, an underground soil layer to be subjected to pile pressing treatment is softened, and therefore obstruction in the pile foundation downward pressing process is reduced, the pile foundation downward moving speed in the pile pressing treatment process is increased, the small-tonnage pile pressing machine can complete pile pressing treatment of high-specification pile foundations, the construction cost is reduced, and the construction time is shortened.

Description

technical field [0001] The invention relates to the technical field of building engineering construction equipment, in particular to a high-pressure water flushing device used in conjunction with a pile driver. Background technique [0002] Pile driver refers to the pile machine that uses static pressure to press piles into the ground. It is used for pile construction in soft soil, such as underground railways, seaports, bridges, reservoir power stations, offshore oil production platforms, and national defense projects. Pile drivers can be divided into two types: mechanical pile drivers and hydraulic pile drivers, among which hydraulic pile drivers have significant advantages such as no vibration, no noise, low cost, and high efficiency, so they are widely used in construction projects , the principle is to use the strong static pressure generated by hydraulic oil to press the prefabricated piles into the foundation smoothly and quietly. As an important component of the hyd...

Problems solved by technology

[0004] In the above-mentioned technical solution, the process of pressing the pile foundation into the ground can be realized by using a pile driver, but some pile foundations that need to be pile-pressed are relatively large, and the use of a conventional pile driver cannot meet the requirements of pile pressing due to its small tonnage. needs, and the cost of switching to a large-tonnage pile driver is high, and it affects the normal construction efficiency of the construction project
