Description
Technical field
The present invention relates to foundation drainages to consolidate field, more particularly, to a kind of continuous forced-ventilated pipe device.
Background technology
For at present, one of most common method is the strong discharging consolidation of rigid forced-ventilated water pipe in Soft Ground field
Method, the method need first to vacuumize, and are sucked the water in surrounding soil in forced-ventilated water pipe by pull of vacuum and groundwater pressure,
Again from air inlet pipe to draining bottom of the tube gas injection, the water in forced-ventilated water pipe is got by injecting high pressure gas；Pumping note repeatedly
Gas, so that foundation drainage consolidates.
However, the patent of the existing mistake of forced-ventilated water pipe of rigid cast, all fails thoroughly to solve problems with：
（1）With regard to the gas injection after pumping, but also in entire forced-ventilated water pipe no longer while the water in forced-ventilated water pipe is got
Possess vacuum（Its interior air pressure is more than an atmospheric pressure）, when vacuumizing again, need first to extract the high pressure gas in drainpipe out；
High pressure gas when gas injection simultaneously can be squeezed out along the filter eye of forced-ventilated water pipe, squeeze the moisture in the soil body near enhancement drainpipe；
And the positive pressure that generates to water in soil of gas injection pumping repeatedly and negative pressure are repeatedly so that water discharge is discontinuous in soil, and is turning
A part of construction time is wasted between alternatively, efficiency reduces.
（2）During forced-ventilated water pipe is constantly filled by the water ejected in soil, the prefabricating load of Groundwater pressure difference is made
With fading away, until it is zero that it, which is pressure difference, when the complete water of forced-ventilated water pipe is full, this process makes the Groundwater pressure difference utilized
It gradually decreases, has lost the prefabricating load pressure difference of draining.The deficiency of this point is a serious defect.
It can be seen that there are energy wastes is larger, the construction period is long, draining for the strong draining concretion method of existing rigidity forced-ventilated water pipe
There are gap and it is inefficient the deficiencies of place.
Invention content
The present invention is to solve the technology of the existing technology for draining discontinuous, loss draining prefabricating load pressure difference to lack
