Abstract

The invention discloses a ramming device and a ramming method. The device comprises a rammer, a rammer board, a supporting mechanism and a ramming force generating mechanism, wherein the supporting mechanism is used for providing support for the rammer and the rammer board so as to enable the rammer and the rammer board to freely move on the supporting mechanism; the ramming force generating mechanism comprises a metal channel and / or a liquid channel used for utilizing a first impact force generated by electrified explosion of metal inside the metal channel, a second impact force generated bythe power supply to the liquid, or the gasification explosion generated by electrified the metal in the metal channel, and third impact force generated by reaction of the metal and the liquid are usedas the driving force of the ramming to drive the rammer board to ram the ground; and meanwhile, the rammer moves towards the air under the action of the driving force, and after a certain height is reached, the rammer falls freely, so that the rammer board is driven by the rammer to rammed the ground the second time. According to the device and the method, the ramming device with simple structure, economy, feasibility, convenient construction, remarkable effect, high efficiency, low energy consumption, safe, reliability, free of pollution and wide application range is provided for foundationcompaction.

Description

technical field [0001] The invention belongs to the field of construction machinery, and more specifically relates to a ramming device and a ramming method. Background technique [0002] The rammer is a kind of mechanical equipment commonly used in the field of construction engineering. In on-site construction, a tamping machine is usually used to tamp and level the ground first, and then perform other engineering operations. Commonly used rammers mainly include fire rammers, frog rammers and vibratory rammers. The fire rammer drives the rammer to ram the soil through the combustion and explosion force of the combustible mixture. It is difficult to accurately control the ramming force, and the exhaust gas is likely to cause serious environmental pollution, and the working conditions of the operators are poor. The frog ram has a simple structure and is easy to control, but its work efficiency is low and its safety is poor. It is generally only suitable for the initial compa...
