Multi-angle barrel type pile-driving method and equipment

Abstract

The invention relates to a multi-angle barrel type pile-driving method and equipment. The method is characterized in that under the working principle of an artillery, and the huge applied force instantly produced by solid gunpowder in burning in a hydraulic toggle rod mechanism is applied to drive a pile body into a foundation in a very short time. The invention also comprises relative equipment.The invention has wide application range and high efficiency, and a pile pipe can not be damaged; the pile body can be driven into the foundation from different angles. The equipment has the advantages of small volume, low energy consumption, easy manufacture and processing, convenient carrying, stable and reliable operation and long service life.

Description

technical field [0001] The invention relates to a multi-angle barrel type piling method and equipment, in particular to a multi-angle barrel type piling method and equipment for civil engineering foundation construction. Background technique [0002] At present, in pile foundation construction, two kinds of piling methods are mainly used, one is percussion piling method, such as steam impact hammer, winch hammer, etc. The disadvantages of this piling method are: large vibration and serious noise pollution. The other is the static pressure piling method, which mainly includes the static pressure hugging piling method and the static pressure top pressure piling method. This piling method has the advantages of stable work, low noise, no vibration, and no damage to the construction foundation, and is favored by people. Special attention, and widely used in construction engineering fields such as buildings, dams, highways and bridges. But above-mentioned two kinds of methods all...

Problems solved by technology

[0002] At present, in pile foundation construction, there are mainly two kinds of piling methods, one is impact piling method, such as steam impact hammer, winch hammer, etc. The disadvantages of this piling method are: large vibration and serious noise pollution

But above-mentioned two kinds of methods all have some self-unsolvable defectives: at first, when running into hard soil layer, just may damage pile or damage pile driver; Secondly, existing pile driver can not drive inclined pile; The maximum pile pressing force is equal to the weight of the pile driver itself. In order to ensure sufficient pile driving force, the weight of the pile driver itself must be increased, which will cause the pile driver to be bulky, heavy, and inconvenient to carry.

There will be the following defects in this way: (1) cylinder and piston rod are too long, and at the same time the piston rod and cylinder will be matched precisely, resulting in difficulties in manufacturing (in terms of current processing level, it is actually difficult to realize) (2) Liquid fuel requires that the fuel chamber formed between the piston and the tail of the cylinder must be well sealed, otherwise the liquid fuel may leak, but because this equipment is not for one-time use, it is impossible to obtain the tightness after multiple explosion pilings Guarantee; (3) Liquid fuel may damage the fuel automatic control system (one-way valve damage) when it burns and explodes; (4) The piling angle cannot be adjusted; (5) Liquid fuel is easy to explode, transportation is inconvenient, and construction is unsafe
