Abstract
The invention discloses a method for rapidly driving a plastic draining plate by electrifying (low-voltage direct current). The method comprises the following steps of: insulating a pipe pile from a vibration hammer by adopting a certain measure; connecting a low-voltage direct-current power supply to the upper end of the pile pipe; switching the direct-current power supply on during driving; and driving the pipe pile in electrified state. In the method, the low-voltage direct-current power supply is provided by adopting a storage battery group and is connected with the upper end of a driven pile pipe of the plastic draining plate, and the direct-current power supply is switched on in the driving process, so that the friction of cohesive soil is reduced, the driving efficiency of the plastic draining plate is increased, and the power consumption is lowered.
Description
Technical field:
The invention belongs to civil engineering groundwork Treatment Design and construction technology, the Soft Ground technical method.Be particularly related to a kind of energising (low-voltage DC) and set the plastic draining board method fast.
Background technology
The reinforced soft soil ground processing method mainly adopts preloading, vacuum method etc. at present, also can adopt combined vacuum and surcharge preloading method, precipitating, pre-pressing method etc.
The vacuum pre-press reinforcing method is proposed by the W.Kjellman of the geological institute professor of Sweden imperial family the earliest nineteen fifty-two.Tianjin harbor Engineering Insitute carried out field trial research in 1980; Nineteen eighty-three is classified country " six or five " key scientific and technological projects as; Through tackling key problem, achieve success, and obtain " vacuum precompression consolidating method of soft soil foundation " and " vacuum combined stack-load method for pre-pressing and reinforcing soft earth foundation " two national inventing patents.Vacuum method has obtained applying in engineerings such as harbour, highway, worker China Democratic National Construction Association, especially gets into 21st century, is used widely in a large amount of reclaiming land around sea engineering that continues to bring out.The area of vacuum prepressing reinforcement soft soil base reaches more than 300 square kilometres up to now.
Because the soft foundation transmission coefficient is less, during reinforcing soft foundation, vertical drainage passage and level need be set to drainage channel, under the effect of prefabricating load, quicken the discharge of soft foundation pore water, reach the reinforcing soft foundation purpose.At present, the vertical drainage passage overwhelming majority all adopts the vibration plastic draining board machine of setting to set.Can be divided into crawler type, rail mounted etc. by walking manner.The vibrating hammer that sets machine provides vibration to set power, and vibrating hammer is connected with the stake pipe.Stake pipe open upper end, the bottom connects changeover portion, and the changeover portion bottom becomes the rectangle outlet bigger slightly than band drain gradually.The draining coiled sheet by stake pipe upper opening through stake tube transitions section outlet at bottom; The band drain end bends and fixes through shoe; Set and propose the stake pipe to the design elevation, shoe and band drain are stayed in the soil body, proposes one section after shoe pass through linkage again with stake pipe proposition ground.
The resistance that sets the stake pipe is mainly the frictional resistance of the soil body to the stake pipe.If can reduce soil body frictional resistance, just can reduce the vibration force of vibrating hammer, can improve the efficient that sets of plastic draining board, also can reduce electric power energy consumption,
Summary of the invention
Order of the present invention provides a kind of energising (low-voltage DC) and sets the plastic draining board method fast.The soil body frictional resistance when reduction plastic draining board sets machine vibration sinking steel pipe, raising sets the efficient that plastic draining board of machine, reduces electric power energy consumption.Be applicable to that the plastic draining board in the stabilization workss such as soft foundation vacuum method, preloading sets, adopt this method, have bigger economic benefit and social benefit.
Particular content of the present invention:
A kind of energising (low-voltage DC) sets the plastic draining board method fast, it is characterized in that: at first take measures to guarantee the insulation of stake pipe and vibrating hammer, connect low-voltage dc power supply in stake pipe upper end then, connect dc source when setting, the charged stake pipe that sets.
(1) adopts the rubber pad insulation between vibrating hammer and the stake pipe;
(2) vibrating hammer adopts rubber pad with stake pipe adpting flange bolt, and flange screw adopts the adhesive rubber insulation processing;

(4) low-voltage dc power supply is connected with stake pipe upper end, and switch is set;
(5) drown oneself before, energized; Cut off the electricity supply behind the tube drawing.
Characteristics of the present invention:
(1) adopts batteries that low-voltage dc power supply is provided, set stake pipe upper end with plastic draining board and be connected, set in the process, connect dc source, reduce the frictional resistance of cohesive soil, improve the efficient that sets of plastic draining board, reduce power consumption.
(2) need do insulation between vibrating hammer and the stake pipe and handle, prevent that direct current from passing through to form the loop between vibrating hammer and the leading truck, cause galvanic loss.
(3) power supply is connected with stake pipe upper end close switch is set, and sets in the process and switches on, and sets to cut off the power supply after accomplishing, and can prevent the consumption of dc source.

The specific embodiment
As shown in Figure 1 is the practical implementation that energising (low-voltage DC) sets the plastic draining board method fast.It is a kind of frictional resistance that plastic draining board sets steel pipe periphery bury that reduces, and forms the plastic draining board method that sets fast.Bury and former ground cohesive soil that the dredging hydraulic reclamation forms have higher viscosity, and plastic draining board sets in the process, set the stake pipe and need overcome bigger cohesive soil frictional resistance.Therefore; At first take measures to guarantee the insulation of stake pipe and vibrating hammer, connect low-voltage dc power supply in stake pipe upper end then, connect dc source when setting; The charged stake pipe that sets; Cohesive soil can significantly reduce the frictional resistance of stake pipe, can set plastic draining board fast, can reduce the power consumption of vibrating hammer motor simultaneously.
