Abstract
The invention relates to geo-material for soft foundation treatment, in particular to a self-suction drain pipe. The self-suction drain pipe is characterized by comprising a pipe body, capillary filler and a filter; the wall of the pipe body is made of a plastic water-pervious pipe provided with water holes; the capillary filler is capillary material filling the pipe body; the filter is made of filter material covering the pipe body. The self-suction drain pipe has the function of active drainage, can replace a plastic drain plate as a vertical drain channel for soft foundation treatment, helps enhance the effect of soft foundation treatment and especially has the effect of supporting the treatment of a deep and thick soft foundation, less than 20m in depth.
Description
Technical field
The present invention relates to the working earth working material of a kind of soft foundation processing, especially a kind of self suction row water pipe.
Background technology
In soft foundation processing engineering construction, plastic draining board is widely used earth working material, and its effect is the drainage channel setting up Vertical dimension in Soft Soil Layer.Plastic draining board comprises plastic plate core and is wrapped in the filter cloth outside plastic plate core, and plate core is harmonica or wavy, is drainage channel; Filter cloth is non-woven fabrics, for isolating the solid particulate matter in Soft Soil Layer.Plastic draining board, as the vertical drain in Soft Soil Layer, is a kind of structure of passive draining, and the water in Soft Soil Layer needs just to discharge by plastic draining board under the effect of the external force such as vacuum preloading or piling prepressing.Because plastic draining board can only the limitation of passive draining and vacuum preloading construction engineering method self, when utilizing prior art to carry out the construction of vacuum preloading soft foundation processing, the optimization process degree of depth is only within 10m, maximum treating depth is also only 20m, does not have effect to the deep layer subgrade more than 20m.
Self suction row water pipe disclosed by the invention be in order to overcome plastic draining board can only passive draining can not the deficiency of Active Drainage, utilize the principle of capillary suction, adopt the structure of Active Drainage, there is the function of Absorb Water, plastic draining board can not only be replaced to use as the vertical drain of soft foundation processing, and just can play the effect of discharging consolidation without the need to External Force Acting.When being performed for more than the vacuum preloading construction of deep layer subgrade of 20m, self suction row water pipe especially can play the effect coordinating vacuum preloading the subgrade of below 20m to be carried out to discharging consolidation.
Summary of the invention
Technical scheme of the present invention is as follows.
1. the working earth working material of soft foundation processing, especially a kind of self suction row water pipe, is characterized in that: it comprises body, capillary obturator and filtering bodies; Described body is the plastics water-permeable pipe that tube wall is provided with permeable hole; Described capillary obturator is the capillary materials be filled in body; Described filtering bodies is the filtering material be wrapped in outside body.
2, the self suction row water pipe as described in technical scheme 1, a preferred technical scheme is: the internal diameter of described plastics water-permeable pipe is 1-10cm, and wall thickness is 0.2-3mm.
3, the self suction row water pipe as described in technical scheme 1, a preferred technical scheme is: the material of described plastics water-permeable pipe is PP or PE.
4, the self suction row water pipe as described in technical scheme 1, a preferred technical scheme is: described plastics water-permeable pipe is bellows.
5, the self suction row water pipe as described in technical scheme 1, a preferred technical scheme is: the aperture of the permeable hole on described plastics water-permeable pipe is 0.5-10mm.
6, the self suction row water pipe as described in technical scheme 1, a preferred technical scheme is: described capillary materials comprises capillary tube or hydrophilic fibre or sponge.
7, the self suction row water pipe as described in technical scheme 1, a preferred technical scheme is: described filtering material comprises filter cloth or filter screen or filter membrane.
8, the self suction row water pipe as described in technical scheme 1, a preferred technical scheme is: the end part seal of described self suction row water pipe its one end down when constructing.
According to technical scheme disclosed by the invention, the tube wall of the body of self suction row water pipe is provided with permeable hole, body is wrapped with filtering bodies, when self suction row water pipe vertically plugs in Soft Soil Layer, water in Soft Soil Layer can enter self suction row water pipe, solid particulate matter in Soft Soil Layer is filtered body and filters and the unlikely self suction row water-pipe blockage drainage channel that enters, and therefore, self suction row water pipe can use as the vertical drain of soft foundation processing.
Moreover, capillary materials is filled with in body due to self suction row water pipe, capillary materials can produce wicking ability in Soft Soil Layer, when the moisture content on self suction row water pipe top is because of natural evaporation or when being pumped because of External Force Acting, the moisture content of self suction row water pipe bottom can be delivered to capillary upper under the effect of capillary water absorption, therefore self suction row water pipe has the function of automatic ink-suction, just can play the effect of discharging consolidation when not having External Force Acting.
Use self suction row water pipe to replace plastic draining board as the Vertical dimension drainage channel of soft foundation processing, can significantly strengthen soft foundation processing effect.Especially when utilizing vacuum preloading to carry out the soft foundation processing of deep layer, self suction row water pipe more can make up the deficiency that vacuum preloading can not process below 20m Soft Soil Layer, in the Soft Soil Layer of below 20m, upwards can transmit moisture content, effectively coordinate vacuum preloading to carry out the construction of deep layer soft foundation processing.
